Activated macrophages and microglia induce dopaminergic sprouting in the injured striatum and express brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor. (1/7861)

Nigrostriatal dopaminergic neurons undergo sprouting around the margins of a striatal wound. The mechanism of this periwound sprouting has been unclear. In this study, we have examined the role played by the macrophage and microglial response that follows striatal injury. Macrophages and activated microglia quickly accumulate after injury and reach their greatest numbers in the first week. Subsequently, the number of both cell types declines rapidly in the first month and thereafter more slowly. Macrophage numbers eventually cease to decline, and a sizable group of these cells remains at the wound site and forms a long-term, highly activated resident population. This population of macrophages expresses increasing amounts of glial cell line-derived neurotrophic factor mRNA with time. Brain-derived neurotrophic factor mRNA is also expressed in and around the wound site. Production of this factor is by both activated microglia and, to a lesser extent, macrophages. The production of these potent dopaminergic neurotrophic factors occurs in a similar spatial distribution to sprouting dopaminergic fibers. Moreover, dopamine transporter-positive dopaminergic neurites can be seen growing toward and embracing hemosiderin-filled wound macrophages. The dopaminergic sprouting that accompanies striatal injury thus appears to result from neurotrophic factor secretion by activated macrophages and microglia at the wound site.  (+info)

Is early post-operative treatment with 5-fluorouracil possible without affecting anastomotic strength in the intestine? (2/7861)

Early post-operative local or systemic administration of 5-fluorouracil (5-FU) is under investigation as a means to improve outcome after resection of intestinal malignancies. It is therefore quite important to delineate accurately its potentially negative effects on anastomotic repair. Five groups (n = 24) of rats underwent resection and anastomosis of both ileum and colon: a control group and four experimental groups receiving daily 5-FU, starting immediately after operation or after 1, 2 or 3 days. Within each group, the drug (or saline) was delivered either intraperitoneally (n = 12) or intravenously (n = 12). Animals were killed 7 days after operation and healing was assessed by measurement of anastomotic bursting pressure, breaking strength and hydroxyproline content. In all cases, 5-FU treatment from the day of operation or from day 1 significantly (P<0.025) and severely suppressed wound strength; concomitantly, the anastomotic hydroxyproline content was reduced. Depending on the location of the anastomosis and the route of 5-FU administration, even a period of 3 days between operation and first dosage seemed insufficient to prevent weakening of the anastomosis. The effects of intravenous administration, though qualitatively similar, were quantitatively less dramatic than those observed after intraperitoneal delivery. Post-operative treatment with 5-FU, if started within the first 3 days after operation, is detrimental to anastomotic strength and may compromise anastomotic integrity.  (+info)

Matrix valency regulates integrin-mediated lymphoid adhesion via Syk kinase. (3/7861)

Lymphocytes accumulate within the extracellular matrix (ECM) of tumor, wound, or inflammatory tissues. These tissues are largely comprised of polymerized adhesion proteins such as fibrin and fibronectin or their fragments. Nonactivated lymphoid cells attach preferentially to polymerized ECM proteins yet are unable to attach to monomeric forms or fragments of these proteins without previous activation. This adhesion event depends on the appropriate spacing of integrin adhesion sites. Adhesion of nonactivated lymphoid cells to polymeric ECM components results in activation of the antigen receptor-associated Syk kinase that accumulates in adhesion-promoting podosomes. In fact, activation of Syk by antigen or agonists, as well as expression of an activated Syk mutant in lymphoid cells, facilitates their adhesion to monomeric ECM proteins or their fragments. These results reveal a cooperative interaction between signals emanating from integrins and antigen receptors that can serve to regulate stable lymphoid cell adhesion and retention within a remodeling ECM.  (+info)

The effects of low-copper diets with or without supplemental molybdenum on specific immune responses of stressed cattle. (4/7861)

Angus bull calves (n = 42; 7 mo of age; 254 kg initial BW) were used to investigate the effects of dietary Cu and Mo on immune function of stressed cattle. Randomly selected calves (n = 22) were injected with 90 mg of Cu as Cu glycinate 28 d before weaning and castrated at weaning. These calves received 7.5 and 5 mg of supplemental Cu/kg of DM during a 41-d receiving phase and a 196-d growing phase, respectively. The remainder of the steers received no supplemental Cu during the experiment. Copper-supplemented steers had adequate Cu status at weaning, whereas unsupplemented calves were marginally Cu-deficient. Cell-mediated response to intradermal injection of phytohemagglutinin was not affected by dietary treatment during the receiving phase. During the growing phase, half of the steers in each Cu treatment were given 5 mg of supplemental Mo/kg of DM. Copper supplementation increased (P<.05) humoral response to ovalbumin injected on d 133 of the growing phase. On d 168 of the growing phase, calves receiving only supplemental Mo were severely Cu-deficient based on plasma and liver Cu concentrations. The other treatment groups had adequate Cu status. Before feeding on d 168 of the growing phase, half of the steers were loaded onto trailers and transported 2.5 h, and they remained on the trailers an additional 9.5 h. Humoral response to porcine erythrocytes (PRBC) and delayed-type hypersensitivity (DTH) to dinitrochlorobenzene was tested at the end of the stress period. There was a Cu x stress interaction for humoral response to PRBC, with Cu decreasing antibody titers in unstressed calves and increasing titers in stressed steers. Stressed steers had lower (P = .03) ADG during the 28 d following stress. The results of this study indicate that Cu deficiency and 5 mg of supplemental Mo/kg of DM do not dramatically alter the specific immunity of stressed cattle.  (+info)

Endothelial implants inhibit intimal hyperplasia after porcine angioplasty. (5/7861)

The perivascular implantation of tissue-engineered endothelial cells around injured arteries offers an opportunity to study fundamental vascular physiology as well as restore and improve tissue function. Cell source is an important issue because the ability to implant either xenogeneic or allogeneic cells would greatly enhance the clinical applications of tissue-engineered grafts. We investigated the biological and immunological responses to endothelial cell xenografts and allografts in pigs 4 weeks after angioplasty of the carotid arteries. Porcine or bovine aortic endothelial cells were cultured within Gelfoam matrices and implanted in the perivascular space of 42 injured arteries. Both porcine and bovine endothelial cell grafts reduced the restenosis index compared with control by 54% and 46%, respectively. Perivascular heparin release devices, formulated to release heparin at twice the rate of release of heparan sulfate proteoglycan from endothelial cell implants, produced no significant reduction in the restenosis index. Endothelial cell implants also reduced occlusive thrombosis compared with control and heparin release devices. Host immune responses to endothelial implants were investigated by immunohistochemical examination of explanted devices and by immunocytochemistry of serum samples. The bovine cell grafts displayed infiltration of leukocytes, consisting primarily of lymphocytes, and caused an increase in antibodies detected in serum samples. Reduced cellular infiltration and no humoral response were detected in animals that received allografts. Despite the difference in immune response, the biological effects of xenografts or allografts did not differ significantly.  (+info)

Effect of leukocytes on corneal cellular proliferation and wound healing. (6/7861)

PURPOSE: To establish whether fucoidin, by blocking the adhesion of leukocytes on the limbal vascular endothelium, prevents extravasation of the cells from the blood stream into the limbal stroma and the wounded area after corneal injury. Successful leukocyte blocking enabled investigation of the influence of leukocytes on corneal cellular proliferation after corneal wounding. METHODS: Thirty-two New Zealand White rabbits were used. Photorefractive keratectomy (PRK) and a standardized alkali corneal wound were used as models in two sets of experiments. In half of the injured rabbits fucoidin was used to prevent leukocytes from leaving the local vessels. The efficiency of the blocking technique was evaluated by counting the number of leukocytes in the limbal and wounded corneal areas. Proliferating cell nuclear antigen (PCNA) was used as a marker for proliferative activity. RESULTS: The infiltration of leukocytes into the limbus and the cornea after PRK and alkali injuries can be blocked by fucoidin. The healing rate of corneal epithelium after alkali burn was retarded in the absence of leukocytes. PCNA expression was enhanced in the presence of leukocytes. Fucoidin per se had no influence on corneal cell proliferation and wound healing. CONCLUSIONS: Polymorphonuclear leukocytes (PMNs) can be prevented from entering the cornea in vivo by fucoidin after PRK and after alkali burn. The corneal epithelial healing rate is delayed in the absence of PMNs in vivo, and PCNA expression increases in the presence of leukocytes.  (+info)

Patterns of healing of scaphoid fractures. The importance of vascularity. (7/7861)

We studied 45 patients with 46 fractures of the scaphoid who presented sequentially over a period of 21 months. MRI enabled us to relate the pattern of the fracture to the blood supply of the scaphoid. Serial MRI studies of the four main patterns showed that each followed a constant sequence during healing and failure to progress normally predicted nonunion.  (+info)

Mid-term results of endoscopic perforator vein interruption for chronic venous insufficiency: lessons learned from the North American subfascial endoscopic perforator surgery registry. The North American Study Group. (8/7861)

PURPOSE: The safety, feasibility, and early efficacy of subfascial endoscopic perforator surgery (SEPS) for the treatment of chronic venous insufficiency were established in a preliminary report. The long-term clinical outcome and the late complications after SEPS are as yet undetermined. METHODS: The North American Subfascial Endoscopic Perforator Surgery registry collected information on 148 SEPS procedures that were performed in 17 centers in the United States and Canada between August 1, 1993, and February 15, 1996. The data analysis in this study focused on mid-term outcome in 146 patients. RESULTS: One hundred forty-six patients (79 men and 67 women; mean age, 56 years; range, 27 to 87 years) underwent SEPS. One hundred and one patients (69%) had active ulcers (class 6), and 21 (14%) had healed ulcers (class 5). One hundred and three patients (71%) underwent concomitant venous procedures (stripping, 70; high ligation, 17; varicosity avulsion alone, 16). There were no deaths or pulmonary embolisms. One deep venous thrombosis occurred at 2 months. The follow-up periods averaged 24 months (range, 1 to 53 months). Cumulative ulcer healing at 1 year was 88% (median time to healing, 54 days). Concomitant ablation of superficial reflux and lack of deep venous obstruction predicted ulcer healing (P <.05). Clinical score improved from 8.93 to 3.98 at the last follow-up (P <. 0001). Cumulative ulcer recurrence at 1 year was 16% and at 2 years was 28% (standard error, < 10%). Post-thrombotic limbs had a higher 2-year cumulative recurrence rate (46%) than did those limbs with primary valvular incompetence (20%; P <.05). Twenty-eight of the 122 patients (23%) who had class 5 or class 6 ulcers before surgery had an active ulcer at the last follow-up examination. CONCLUSIONS: The interruption of perforators with ablation of superficial reflux is effective in decreasing the symptoms of chronic venous insufficiency and rapidly healing ulcers. Recurrence or new ulcer development, however, is still significant, particularly in post-thrombotic limbs. The reevaluation of the indications for SEPS is warranted because operations in patients without previous deep vein thrombosis are successful but operations in those patients with deep vein thrombosis are less successful. Operations on patients with deep vein occlusion have poor outcomes.  (+info)

This study has two arms: 1) the biopsy arm and 2) the debridement arm. The purpose of the biopsy arm is to determine whether there are similar patterns of genes being turned on and/or turned off among people with healing and non-healing wounds. The purpose of the debridement arm is to (i) identify the nature of bacterial infection and the genes driving the tissue response to it; and (ii) determine how the biofilm components arrest/paralyze the immune function.. For the biopsy arm, a single subject (current OSU Comprehensive Wound Center patient) will provide 2 tissue samples (3 mm punch biopsy samples collected by a wound care physician) from a single wound over a 4-week time period. The wound and the samples will be categorized as healing versus non-healing responses on the basis of decreased (healing) or increased (non-healing) wound area measurements over the 4-week time period. A chronic wound generally is a wound which shows no signs of significant healing in four weeks or has not healed in ...
The Wound Healing Center offers a comprehensive wound management approach to healing through our clinics interdisciplinary team approach. As an outpatient, appointment-based program, the Wound Care Centers staff is committed to providing each patient with an advanced, individualized treatment plan for their chronic, non-healing wounds. These wounds are defined as sores or wounds that have not significantly improved from conventional treatments. Typically, a wound that does not respond to normal medical care within 30 days is considered a problem wound. Associated with inadequate circulation, poorly functioning veins, and immobility, non-healing wounds tend to lead to lower quality of life, as well as potential amputation. When wounds persist, a specialized approach is required for healing. This is where the Wound Care Center can help.. About Healogics ...
Background and Objectives: We have previously demonstrated the efficacy of a non-invasive, non-contact, fast and simple but robust fluorescence imaging (u-FEI) method to monitor the healing of skin wounds in vitro. This system can image highly-proliferating cellular processes (295/340 nm excitation/emission wavelengths) to study epithelialization in a cultured wound model. The objective of the current work is to evaluate the suitability of u-FEI for monitoring wound re-epithelialization in vivo. Study Design: Full-thickness wounds were created in the tail of rats and imaged weekly using u-FEI at 295/340nm excitation/emission wavelengths. Histology was used to investigate the correlation between the spatial distribution and intensity of fluorescence and the extent of wound epithelialization. In addition, the expression of the nuclear protein Ki67 was used to confirm the association between the proliferation of keratinocyte cells and the intensity of fluorescence. Results: Keratinocytes forming ...
A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time the way most wounds do; wounds that do not heal within three months are often considered chronic. Chronic wounds seem to be detained in one or more of the phases of wound healing. For example, chronic wounds often remain in the inflammatory stage for too long. To overcome that stage and jump-start the healing process a number of factors need to be addressed such as bacterial burden, necrotic tissue, and moisture balance of the whole wound. In acute wounds, there is a precise balance between production and degradation of molecules such as collagen; in chronic wounds this balance is lost and degradation plays too large a role. Chronic wounds may never heal or may take years to do so. These wounds cause patients severe emotional and physical stress and create a significant financial burden on patients and the whole healthcare system. Acute and chronic wounds are at opposite ends of a ...
Purpose. The reepithelialization of the corneal surface is an important process for restoring the imaging properties of this tissue. The purpose of the present study was to characterize and validate a new human in vitro three-dimensional corneal wound healing model by studying the expression of basement membrane components and integrin subunits that play important roles during epithelial cell migration and to verify whether the presence of exogenous factors could accelerate the reepithelialization. Methods. Tissue-engineered human cornea was wounded with a 6-mm biopsy punch, and the reepithelialization from the surrounding margins was studied. Biopsy samples of the reepithelialized surface were harvested 3 days after wounding and were processed for histologic, electron microscopic, and immunofluorescence analyses. The effects of fibrin and epithelial growth factor (EGF) on wound reepithelialization were also studied. Results. Results demonstrated that this in vitro model allowed the migration of ...
The development of wound management protocols and guidelines such as the T.I.M.E. acronym are useful tools to aid wound care practitioners deliver effective wound care. The T.I.M.E. framework provides a systematic approach for the assessment and management of the majority of acute and chronic wounds. The debridement of devitalised tissue from the wound bed, the reduction in wound bioburden and effective management of wound exudate - i.e., wound bed preparation - are barriers to wound healing progression that are targeted by T.I.M.E. There are a large number of wound dressings available to experienced wound care practitioners to aid in their goal of healing wounds. Despite the systematic approach of T.I.M.E., the large number of wound dressings available can introduce a level of confusion when dressing choices need to be made. Any simplification in dressing choice, for example by choosing a dressing system comprising of a limited number of dressings that are able to address all aspects of ...

Healthcare Developments Paving the Way. Technological advancements in wound tissue analysis solutions such as the development of fluorescence tagging solutions providing visual validation of wound infection, growing sensitivity and selectivity of wound tissue analysis solutions, robustness of detection unaffected by impurities such as concurrent antibiotic use, faster detection than conventional tissue analysis, lower healthcare costs, identification of antibiotic resistance are increasing the adoption of wound tissue analysis solutions. However, lack of awareness and difficulties in accurately ...
Non-healing wound is a delay in the natural healing process from either an outside or inside source. Inside sources could be and infection, bleeding, drainage, clots, fatty necrosis, unexpected debris, tracks, and underlying health issues such as diabetes and poor circulation. Outside sources could be pressure, friction, moisture, trauma, burn, radiation and insects (roaches or maggots). All of these sources make each patient and circumstance unique and different and should be treated with individual care.. As a wound practitioner my responsibility is to find the delay or non- healing source quickly for every patient. Early detection will reduce pain, suffering and return patients to their lifestyle.. Our wound care clinic is unique because our staff is physical therapist and assistances that specialize in wound care and debridement.

Methods: Four groups of eight Sprague dawley female rats in each group were used for the study. Under anesthesia, excision wound of 300 mm2 size was created using scissors. Group 1 served as control with no drugs applied. Group 2, 3 and 4 were applied with mupirocin, KV and KT respectively daily until wound was completely healed. Parameters observed were % wound contraction rate and epithelialization period. Biopsy of wound for histology was taken on day 12 as well as the healed wound was taken after the wound was healed. Results were analyzed by one-way analysis of variance (ANOVA) followed by Tukeys test by keeping p,0.05 as statistically significant. ...
In the current study, diabetic mice exhibited delayed mucosal wound healing compared with normoglycemic mice when small mucosal wounds were created on the dorsal tongue surface. One day after wounding, diabetic wound gaps were 71% larger than corresponding wounds in normoglycemic mice. All the wounds in normoglycemic mice had a high degree of healing after 2 days, whereas only 17% of the diabetic mice exhibited this degree of healing. Mechanistically, the impaired healing in diabetic animals can be explained by a large decrease in epithelial migration (83%) and a moderate decrease in proliferation (54%). The in vivo results were supported by in vitro experiments, which demonstrated that high glucose significantly reduced migration of oral epithelial cells by 54% and proliferation by 33%. Thus, diabetes affects healing of mucosal wounds by negatively affecting migration and proliferation. The result contrasts with cutaneous wound healing in which hyperglycemia has a profound effect on migration ...

Both MMP-9 and MMP-13 were expressed by the ...
Open wound management in small animals is a common event in veterinary practice. It is economically significant and can cause considerable distress and pain to the animal. The aim of wound management is to provide conditions that allow for optimal wound healing or to prepare the wound for definitive closure by reconstructive techniques. However, every wound is unique and this problem is reflected in the paucity of published studies analysing the effectiveness of wound dressing products in the management of small animal wounds. Wounds must be properly evaluated at the first presentation in order to plan a treatment protocol and to give the owner an indication of the expected duration of treatment and ultimately the prognosis. This chapter considers how to manage open wounds and how to use dressings and bandages to optimize the healing process.

Many wounds are compromised by a local wound environment which is fundamentally detrimental to healing. Often this arises due to an imbalance between the stimulation and inhibition of proteases within the wound.(11) As a result, a chronic inflammatory state often exists with high levels of proteases within the wound bed, which serve to damage the growth factors and cells required for wound repair.(11) Indeed, Yager and colleagues(11) demonstrated that, compared with surgical wounds, there was an imbalance between proteases and their inhibitors in pressure ulcer wound fluid. The concern is that, in the presence of elevated protease activity, there is a 90% chance that the wound will not heal.(12) Conversely, not all non-healing wounds have excess levels of proteases; indeed, the study demonstrated that just 28% of wounds had elevated protease activity, suggesting that there must be other contributing factors which are delaying healing ...

Chronic wounds affect approximately 2% of the U.S. population at any given time. Animal models can not simulate the complex set of pre-existing conditions in each individual that results in failed wound healing. Therefore, human subjects must be used to obtain valid data. Adequate wound vascularization that permits blood vessels to deliver oxygen to the wound is a requirement for wound healing to occur. This protocol will attempt to gain greater understanding of the mechanisms of chronic wounds through 3 specific aims: 1) identify the angiogenic mechanisms in wound site macrophages, which are required for healing, 2) determine the impact of stress and glucocorticoid resistance on endothelial cell and macrophage biology and ultimately wound healing outcomes, 3) identify patterns of gene expression in wound endothelial cells that are found in healing versus non-healing wounds. This data will be correlated with the wound oxygenation status to determine the impact of wound vascularization on the ...
TY - GEN. T1 - Wound closure rates in human organotypic skin models are increased by connexin mimetic peptides. AU - Wright, Catherine. AU - Hodgins, Malcolm B.. AU - Martin, Patricia. PY - 2008. Y1 - 2008. N2 - Recent studies suggest significant increases in skin wound healing rates occur by altering gap junction intercellular communication. Connexin mimetic peptides, which directly target specific connexins (Cx), have great therapeutic potential. Thus we analysed their effect on cell migration responses during wound closure in an organotypic human skin model. Primary skin fibroblasts and keratinocytes were derived from child foreskins obtained with ethical approval and patient consent. Keratinocytes were seeded onto Transwell inserts following culture of dermal fibroblasts on their undersides. Cells were cultured to confluence, and then exposed to the air-liquid interface forming organotypic living skin equivalents. Immunocytochemistry determined connexin and differentiation marker expression ...
For most people, simple injuries and wounds heal quickly without the need for advanced medical treatments. For these people, over the counter antibiotic ointments and bandages are more than sufficient. Unfortunately, however, a large portion of the population is afflicted by chronic wounds on their feet, ankles or legs. While diabetes and a condition called venous stasis are the most commonly seen reasons for chronic wounds, those with other conditions or health restrictions may develop them as well. No matter what the cause of a persons chronic wound, it is crucial to get treatment from a certified podiatrist or other medical specialist as soon as possible for Chronic Wound Treatments in Joliet IL. Failure to do so can lead to serious health complications.. Chronic wounds are ones that do not heal properly on their own in a normal length of time. While there is some disagreement as to what constitutes a chronic wound, it generally refers to those that do not heal within two months or longer. ...
For hundreds of years poor and chronic nonhealing wounds have constituted a serious problem to medicine. What is more, treating such wounds is an expensive let alone a long-lasting process. The following paper describes Professor Schellers achievements in using propolis for poor and chronic non-healing wounds. The authors intention was to present the results connected with the use of the ethanolic extract propolis, in the treatment of patients suffering from burns, venous crural ulceration, local sacral bone pressure ulcers, suppurative osteitis and arthritis, suppurative postoperative local wound complications, and infected traumatic wounds.
The Wound Center is a resource that is available to help anyone suffering from chronic or non-healing wounds. We work with an interdisciplinary team of surgeons, podiatrists, and specially trained nursing staff to develop a treatment plan that is patient-specific. Chronic or non-healing wounds can be malodorous, painful, and can inhibit people from living the active lifestyle that they desire.. Our goal is to treat not only the wound, but the patient as a whole. We teach patients, family members, and caregivers how to care for wounds at home to further facilitate healing. Patients have access to physical therapy, nutritionists, home health services and diabetic educators to ensure faster, specialized healing.. Our clinic treats a variety of wound types including:. ...
All wounds are contaminated with bacteria; the decision to perform a wound swab is based on the presence of clinical signs and symptoms of infection. In acute wounds these include: pain, erythema, localised oedema, heat and purulence. Patients with chronic wounds may display covert signs of infection such as: an increase in serous exudate, delayed healing, friable granulation tissue, pocketing at the wound base and malodour. A wound swab should only be performed when the wound has been clinical diagnosed as infected. The problem that arises for the clinician is which method of collecting the wound swab should be employed.The aim of this research was to compare two semi-quantitative wound-swabbing techniques (Levine versus Z technique) to establish which method was more effective in determining the presence of bacteria in cutaneous wounds. The Levine technique involves rotating the wound swab over a 1 cm[superscript]2 area of the wound with sufficient pressure to express fluid from within the ...
Can one tell if a wound is healing? As basic as this question is, it is not easily answered using current practice for the treatment of diabetes-related foot ulcers (DFU). It is well known that DFU surface area changes at 4 weeks are highly predictive of subsequent wound closure.(Sheehan, Jones et al. 2003, Robson, Cooper et al. 2006, Steed, Attinger et al. 2006, Snyder, Cardinal et al. 2010) Simply providing this information to wound care providers improves wound healing outcomes.(Kurd, Hoffstad et al. 2009) Additionally, the quality and quantity of the tissue in the wound bed also offers important prognostic information.(Sherman 2003, Valenzuela-Silva, Tuero- Iglesias et al. 2013) Unfortunately outside of the research setting, accurate measurement of wound surface area changes and quantification of the wound base are out of reach in the busy wound practice setting. Currently, clinicians estimate wound size by estimating wound width and length using a scalpel after wound treatment. There is a ...
Human monocyte-seeded hydrogels significantly improved healing compared to un-seeded control hydrogels with an average time to complete healing of 17.8 days in the monocyte group versus 21 days in the control group (*p,0.005). Histologic analysis revealed that transplanted human monocytes differentiated primarily into M2 wound phenotype macrophages by day 2 following transplantation. Endogenous mouse macrophages within the wound site displayed a similar phenotype. Transplanted monocytes persisted in the wound site until day 8 of wound healing. Although the rate of wound healing was increased, endpoint scar size and quality was not affected in wounds receiving human monocytes as compared to control-treated wounds ...

A wound is a type of injury which happens relatively quickly in which skin is torn, cut, or punctured (an open wound), or where blunt force trauma causes a contusion (a closed wound). In pathology, it specifically refers to a sharp injury which damages the dermis of the skin. According to level of contamination, a wound can be classified as: Clean wound - made under sterile conditions where there are no organisms present, and the skin is likely to heal without complications. Contaminated wound - usually resulting from accidental injury; there are pathogenic organisms and foreign bodies in the wound. Infected wound - the wound has pathogenic organisms present and multiplying, exhibiting clinical signs of infection (yellow appearance, soreness, redness, oozing pus). Colonized wound - a chronic situation, containing pathogenic organisms, difficult to heal (i.e. bedsore). Open wounds can be classified according to the object that caused the wound: Incisions or incised wounds - caused by a clean, ...
A non-healing wound is essentially stuck in a highly oxidative, inflammatory loop. Essentially, this is a state of oximation, a combination of oxidative stress and inflammation that has been described in detail in previous issues of Holistic Primary Care. (Read Dr. Roby Mitchells Oximation in Practice series).. It should be obvious that we want to do whatever we can to reduce inflammation. Bear in mind that its not just the wound thats inflamed; in most of these cases the patients entire body is in a hyper-inflammatory state.. Much of the so-called, the normal aging process (atherosclerosis, decreased kidney function, arthritis, heart failure, cognitive decline) is directly linked to a process called glycation, in which glucose molecules are combined with dietary fat and proteins to form advanced glycation end products, otherwise known as glycotoxins. These, in turn, crosslink with different proteins in body tissues, compromising their function.. This process is greatly accelerated ...

Cutaneous wounds are a largely unrecognized, spiraling epidemic that affects millions of people worldwide. Healing and regeneration of wounds is a complex process that has at its core a functional inflammatory response that initiates the repair process and fights against infective pathogens. Wound inflammation is a tightly regulated process involving neutrophils, macrophages, mast cells, and various leukocytes and tissue restoration mechanisms working in concert to allow healing and tissue restoration following injury. However, in many conditions, dysregulated and/or prolonged inflammation leads to the development of chronic wounds and contributes to excessive scar formation.Over the past few decades, scientific advances have greatly contributed to our current understanding of the complex molecular and cellular pathways that govern the natural progression of wound inflammation. The use of different in-vitro systems and experimental animal models has significantly improved our understanding of

Diabetic, non-healing wounds are a major clinical problem with considerable morbidity and associated financial costs. However, mechanisms by which diabetes impedes tissue repair mechanisms remain unclear. Previous studies have suggested decreased tissue levels of growth factors, including keratinocyte growth factor, VEGF, PDGF, excess protease activity, decreased angiogenesis, altered inflammation, or an increased microbial load as possible contributing factors for the impaired wound healing observed in diabetes mellitus (Galkowska et al, 2006; Brem & Tomic-Canic, 2007; Grice et al, 2010; Gardner et al, 2013; Eming et al, 2014; Pastar et al, 2014; Lindley et al, 2016; Quinn et al, 2016; Ramirez et al, 2018). In this study, we discovered that the Notch pathway activity is elevated in fibroblasts of human diabetic ulcers and diabetic murine wounds, but not in normal murine acute wounds and non-diabetic ischemic wounds. Furthermore, we uncovered the Notch1 pathway as an important molecular ...

Chronic wound is an important national healthcare problem, compounded by the fact that patients with chronic diseases such as diabetes are always vulnerable to develop chronic wounds. Wound care research has two strands: clinical and computational. On the clinical side, research has been focusing on how to effectively treat wounds. This includes measuring wounds, tracking their progression with time, and assessing their health. On the computational side, little has been done to treat a wound as an engineering system that needs to be modeled and analyzed with the ultimate goal of predicting the progress of wound healing and determining the factors that influence wound healing.. ...

Diabetic non-healing wounds are a major clinical problem. The mechanisms leading to poor wound healing in diabetes are multifactorial but unresolved inflammation may be a major contributing factor. The complement system (CS) is the most potent inflammatory cascade in humans and contributes to poor wound healing in animal models. Signal transducer and activator of transcription 4 (STAT4) is a transcription factor expressed in immune and adipose cells and contributes to upregulation of some inflammatory chemokines and cytokines. Persistent CS and STAT4 expression in diabetic wounds may thus contribute to chronic inflammation and delayed healing. The purpose of this study was to characterize CS and STAT4 in early diabetic wounds using db/db mice as a diabetic skin wound model. The CS was found to be activated early in the diabetic wounds as demonstrated by increased anaphylatoxin C5a in wound fluid and C3-fragment deposition by immunostaining. These changes were associated with a 76% increase in ...

Diabetic wounds are the most severe type of chronic wounds that largely impair the quality of life in patients and inflict an enormous burden on the healthcare system. World-wide, there are more than 350 million diabetic patients and about 20% of them develop diabetic foot ulcers that often do not heal, which eventually lead to amputation. Chronic eardrum perforations are another type of chronic wounds. Today the only existing treatment of chronic eardrum perforations is through surgery.. In his thesis, Yue Shen demonstrates that plasminogen, a well-known plasma protein, acts as a key regulatory molecule of inflammation that can be used to treat different types of chronic wounds including diabetic wounds and chronic eardrum perforations. Yue Shen demonstrates that the level of plasminogen dramatically increases in and around wounds, which leads to an enhanced inflammation that is required for healing. In diabetic wounds that do not heal, the level of plasminogen does not increase and the ...

Biofilms in human wounds are considered responsible for the non-healing nature of some chronic wounds. Recent advancements in chronic wound healing have resulted from an increased understanding and awareness of biofilms. These findings led to the hypothesis that bacterial biofilms were also present within the wound bed of non- healing equine wounds and could be responsible for the unexplained retardation of some chronic equine wounds. This study aimed to collect and present information regarding the microbiological composition of equine wounds and to present evidence supporting the presence of bacterial biofilms within these wounds. The objectives were firstly to gain an understanding of the common bacterial microflora in horse wounds and on horse skin. To achieve this, the study utilised culture and molecular techniques, where molecular techniques included denaturing gradient gel electrophoresis (DGGE) and gene sequencing. Secondly, the study examined chronic wounds for in-vivo evidence of ...
TY - JOUR. T1 - Stress-induced susceptibility to bacterial infection during cutaneous wound healing. AU - Rojas, Isolde Gina. AU - Padgett, David A.. AU - Sheridan, John F.. AU - Marucha, Phillip T.. PY - 2002/1/1. Y1 - 2002/1/1. N2 - Psychological stress delays wound healing and decreases immune/inflammatory responses required for bacterial clearance. To determine if stress increases the susceptibility to wound infection, female SKH-1 mice were subjected to restraint stress (RST) beginning 3 days prior to the placement of cutaneous wounds. Viable bacteria were quantified from harvested wounds. RST delayed healing by 30% and caused a 2- to 5-log increase in opportunistic bacteria (e.g., Staphylococcus aureus) when compared to wounds from control animals (p , .05). By day 7, 85.4% of the wounds from RST mice had bacterial counts predictive of infection compared to 27.4% from control mice (p , .001). To assess the role of RST-induced glucocorticoids in bacterial clearance, mice were treated with ...

Non-healing wounds of the diabetic foot are considered one of the most significant complications of diabetes, representing a major worldwide medical, social, and economic burden that greatly affects patient quality of life. Almost 24 million Americans-one in every twelve-are diabetic and the disease is causing widespread disability and death at an epidemic pace, according to the Centers for Disease Control and Prevention. Of those with diabetes, 6.5 million are estimated to suffer with chronic or non-healing wounds. Associated with inadequate circulation, poorly functioning veins, and immobility, non-healing wounds occur most frequently in the elderly and in people with diabetes-populations that are sharply rising as the nation ages and chronic diseases increase. Although diabetes can ravage the body in many ways, non-healing ulcers on the feet and lower legs are common outward manifestations of the disease. Also, diabetics often suffer from nerve damage in their feet and legs, allowing small ...
A significant feature of all wounds is the likelihood of pathological infection occurring. Surgical wounds are no exception, and average levels of infection of surgical wounds are 7%-10% dependent on the procedure. These infections can be prevented by appropriate cleanliness, surgical discipline and skill, wound care therapy, and antibiotic prophylaxis. Infections usually lead to more extensive wound care time, the use of more expensive products and drugs, significantly increased therapist time, and increased morbidity and rehabilitation time. A large number of wounds will also be sutured to accelerate closure, and a proportion of these will undergo dehiscence and require aftercare for healing to occur.. Traumatic Wounds. There are estimated to be 1.5 million cases of traumatic wounding every year. These wounds require cleansing and treatment with low adherent dressings to cover them, prevent infection, and allow healing by primary intention. Lacerations are a specific type of trauma wound that ...
Around 6.5 million patients in the U.S. suffer from chronic wounds, such as pressure injuries or ulcers. Treatment costs $25 billion each year, representing a sizable and growing problem. Despite the wide impact of chronic wounds, its rare to see specialized, effective wound care delivered across the care continuum.. A chronic non-healing wound is a surrogate marker for illness. These patients require holistic management of their co-morbidities and continuity across care settings.. Despite this, a great deal of emphasis has been placed on treating wounds as singular events, managed topically with expensive dressings and support surfaces. This is only a small part of wound healing.. As a physician focused solely on wound care, I have learned that we must shift the focus from simply treating the wound to treating the wounded patient. The impact in the post-acute care setting in particular is worthy of evaluation and discussion, as up to 29% of patients in long-term care facilities will experience ...

  • In instances where there is a lack of macrophages present, the application of 'synthetic' electric fields using clinical devices would assist the repair process, not only by attracting macrophages to damaged sites to support healing but also by changing their properties to facilitate wound repair and importantly to reduce infection," said Heather M. Wilson from the University of Aberdeen, Aberdeen, U.K. (
  • Phagocytosis is an important process in wound healing whereby macrophages clean the wound site, limit infection and allow the repair process to proceed. (
  • The phases of wound healing normally progress in a predictable, timely manner, and if they do not, healing may progress inappropriately to either a chronic wound such as a venous ulcer or pathological scarring such as a keloid scar [ 3 ]. (
  • Collagen is also deposited at the site of the wound, granulation tissues is formed and the new extracellular matrix is grown. (
  • In addition, this book shows that lactoferrin is a potent regulator of dermal fibroblasts and epidermal keratinocytes, and promotes skin or corneal epithelial wound healing by increasing their proliferation, migration or deposition of extracellular matrix (ECM) components such as collagen and hyaluronan. (
  • The idea behind these collagen grafts is to create a sort of scaffolding into the wound, upon which a patient's cells can attach and grow. (
  • Proliferation (growth of new tissue): In this phase, angiogenesis , collagen deposition, granulation tissue formation, epithelialization, and wound contraction occur. (
  • Also called maturation phase of wound healing, the phase is when collagen is remodeled from type III to type I and the wound fully closes. (
  • Fibroblasts are cells that synthesize the extracellular matrix and collagen that play a critical role in wound healing while keratinocytes are the predominant cells found in the epidermis, the outermost layer of the skin. (

(
  • However, several days of moist dressings will produce a clean wound base, better able to respond to further treatment. (
  • Dressings deliver significant amounts of oxygen to the wound site. (
  •, called Oxygenesys TDO (topical dissolved oxygen), work by delivering dissolved oxygen directly into the wound through dressings. (
  • These lab findings were extended by wound-healing experiments in which [the company's lead scientist] showed that wounds in animals healed faster with oxygenated dressings than with plain dressings. (
  • A considerable body of literature is devoted to methods for improving wound-healing, both in terms of increasing rates of healing and avoiding undesirable effects associated with natural wound-healing processes, such as scarring and contraction of healed tissue. (
  • During contraction, myofibroblasts pull the wound edges closer together to decrease the size of the wound. (
  • It involves continuous cell-cell interaction and cell-matrix interactions that allow the process to proceed in different overlapping phases and processes including inflammation, wound contraction, reepithelialization, tissue remodelling, and formation of granulation tissue with angiogenesis. (
  • [9] In wound contraction, myofibroblasts decrease the size of the wound by gripping the wound edges and contracting using a mechanism that resembles that in smooth muscle cells. (
  • Whilst adult wound front epidermal cells crawl forwards over the exposed substratum to close a defect, a gap in the embryonic epidermis is closed by contraction of a rapidly assembled actin purse-string. (
  • In the adult wound situation connective tissue contraction is brought about by specialist contractile myofibroblasts, but in the embryo standard embryonic fibroblast exert similar tractional forces to bring the wound margins together. (
  • Our research shows that the likely cause of secondary PTH is epithelial separation and wound contraction occurring concurrently with neovascularization. (
  • Our lab developed a growth factor intervention that altered the timing of the wound healing events so that wound contraction and epithelial separation occurred prior to maximal neovascularization. (
  • Wound healing in diabetes is a complex process, characterised by a chronic inflammation phase. (
  • The exact mechanism by which this occurs is not fully understood, and whilst several treatments for healing diabetic wounds exist, very little research has been conducted towards the causes of the extended inflammation phase. (
  • Wound repair consists of three separate but overlapping phases, i.e., inflammation, formation of new tissue, and remodeling. (
  • Wound healing progresses via 3 overlapping phases: inflammation, granulation, and tissue remodeling. (
  • After cutaneous injury, a blood clot forms, and inflammatory cells infiltrate the wound, secreting cytokines and growth factors to initiate the inflammation phase. (
  • Our results provide direct visual evidence of a physical link between wound-associated inflammation and the development of skin cancer," says EMBO Member Paul Martin , professor at Bristol University and the University of Cardiff. (
  • Histology of wounds from IL6 deficient mice displayed no epithelial bridge formation, minimal granulation tissue formation and little inflammation. (
  • Electric fields enhanced the uptake and clearance of a variety of targets known to promote inflammation and impair healing. (
  • Diabetes leads to a decrease in angiogenesis, delaying wound closure which can lead to a common occurrence, namely, non-healing wounds. (
  • Diabetes also alters the ability of macrophages to switch from a pro-inflammatory phenotype to a pro-reparative phenotype, which increases the inflammatory profile in diabetic wounds. (
  • Diabetes disrupts wound healing in many ways but the effect it has on angiogenesis is a major contributor to the delayed wound healing seen in diabetic patients. (
  • Philadelphia, PA, November 27, 2012 - Delayed wound healing is a major complication of diabetes because the physiological changes in tissues and cells impair the wound healing process. (

  • Histological evaluation of skin biopsies showed that wounds treated with GHRH and JI-38 were both characterized by increased abundance of fibroblasts during the early stages of wound healing and accelerated reformation of the covering epithelium at later stages. (
  • Given the responsiveness of fibroblasts to GHRH and recent evidence suggesting a role for GHRH in cell migration ( 23 ), we tested the hypothesis ( 24 ) that GHRH plays a role in promoting skin wound healing and repair, a complex process in which concerted proliferation, migration, and reorganization of fibroblasts play an essential role ( 25 ). (
  • Earlier reports suggested that infiltrating macrophages contribute to lymphangiogenesis as the major producer of vascular endothelial growth factor C (VEGF-C) in cutaneous wound healing. (
