Mechanical, bioadhesive strength and biological evaluations of chitosan films for wound dressing. (1/45)

PURPOSE: To investigate the suitability of chitosan films prepared using two different solvents, acetic acid (Chitosan-AA) and lactic acid (Chitosan-LA), for wound dressing, in comparison with a commercial preparation, Omiderm. METHODS: The mechanical and in-vitro bioadhesive strength properties of Chitosan-AA, Chitosan-LA, and Omiderm were investigated using texture analyzer equipment. The vapour permeability of chitosan films was determined using a method for evaluation of moisture permeability of containers and packaging material described in USP XXII. In addition, the biological evaluations were performed via primary skin irritation, intracutaneous, and systemic injection tests. RESULTS: The three preparations differed significantly in terms of the mechanical and bioadhesive strength properties. Chitosan-LA exhibited a lower tensile strength, but more flexible and bioadhesive than Chitosan-AA. Chitosan film was found to be permeable to water vapour. Chitosan-LA and Omiderm were non-irritant and did not cause any skin allergic reaction. In contrast, Chitosan-AA films inflicted adverse skin reactions. Nevertheless, no gross sign of toxicity was encountered from the systemic injection of the extracts of the three preparations. CONCLUSION: Chitosan films demonstrated significantly different mechanical and bioadhesive strength properties from Omiderm. Chitosan-LA was more soft, flexible, pliable and bioadhesive when compared to Chitosan-AA films. Furthermore, Chitosan-LA did not cause erythema, edema and systemic toxicity. Hence, Chitosan-LA film is suitable to be used in the management of wound healing and skin burn.  (+info)

Peptide-binding assessment using mass spectrometry as a new screening method for skin sensitization. (2/45)

Skin sensitization potential of low molecular weight chemicals was assessed by analyzing peptide-conjugate formation. Chemicals were incubated with a peptide, glutathione, and resultant mixtures were analyzed by mass spectrometry. Eighteen chemicals were assessed, and new peaks corresponding to chemical-peptide conjugates were detected for 13 of 14 known sensitizers. Conjugates were not detected for 4 negative chemicals. The method has advantages as a simple screening assay for assessing the sensitization potential of chemicals.  (+info)

Preliminary pharmacological study of purified snake enzymatic cream isolated from Agkistrodon Halys venom. (3/45)

To investigate the pharmacological and toxicological actions of purified snake enzymatic cream (PSE) isolated from Agkistrodon Halys Venom, erythematous dermatitis was induced by applying dinitrofluorobenezene (DNFB) on the back skin of guinea pigs. Consequent local alterations at different doses of PSE were observed and compared using negative control methods. In skin irritation and acute toxicological experiments, 500 times the effective doses were used in artificially lesioned skin. The marking criteria in the former were based on local manifestations, and in the latter, on changes of some indicators including body weight, breath, and heart rate before and after the experiments. PSE significantly alleviated erythematous dermatitis (p < 0.01, t test) without systemic or local adverse drug reactions within 7 days. PSE as a new drug candidate poses a bright prospect in the prevention and treatment of dermatitis.  (+info)

Comparison of poultice-type and tape-type patches containing ketoprofen on human skin irritation. (4/45)

Although the patch test for visual skin observation is widely used clinically, it does not allow the mechanisms of side effects to be assessed. In this study, we examined poultice-type KP801 and tape-type KP-T patches containing ketoprofen. The parameters to measure side effects on skin were peeling intensity, amount of stripped stratum corneum, skin moisture and redness of skin color under various mechanical conditions. Since the amount of stripped stratum corneum with the tape-type KP-T patch was higher than with the poultice-type KP801 patch, the bio-adhesive strength of the latter was concluded to be lower. A clear relationship exists between the amount of stripped stratum corneum and skin moisture after tape-type patch removal, but this was not found with the poultice-type patch because of its hydration effects. Peeling intensity, one parameter to predict pain at the time of patch removal, was higher with the KP-T. As for mechanical conditions, when the patch is removed, it is important to remove it as slowly as possible and horizontally, and to avoid any rise in skin temperature. Finally, when a patch is applied to a region with little skin moisture, the amount of stripped stratum corneum may increase accordingly.  (+info)

Optimisation of the EpiDerm test protocol for the upcoming ECVAM validation study on in vitro skin irritation tests. (5/45)

An ECVAM-funded prevalidation study (PV) was conducted during 1999 and 2000 to identify in vitro tests capable of reliably distinguishing between skin irritants (I) and non-irritants (NI) according to European Union risk phrases ("R38" or no classification). The tests evaluated were EpiDerm, EPISKIN, PREDISKIN, the non-perfused pig ear method, and the mouse skin integrity function test (SIFT). Whereas reproducibility of the two human skin model tests and SIFT was acceptable, none of the methods was deemed ready to enter a formal validation study due to their low predictivity. The ECVAM Skin Irritation Task Force therefore suggested improvements of protocols and prediction models for these tests. Furthermore, it was agreed that experience gained with the two human-skin models be shared, and a common protocol should be developed for EpiDerm and EPISKIN (Zuang et al., 2002). When we applied an improved EPISKIN protocol (Portes et al., 2002) to the EpiDerm model, an acceptable specificity (80%) was achieved, whereas the sensitivity (60%) was far too low. In 2003, the EPISKIN protocol was further refined by extension of the post-incubation period following chemical exposure. In the current study, we evaluated this EPISKIN refinement by applying it to EpiDerm. In addition, we developed technical improvements for the application of the test chemicals and rinsing procedure, which reduced the variability of results and increased the percentage of correct predictions. A set of twenty non-coded reference substances from the ECVAM prevalidation study phase III (Fentem et al., 2001) was tested with the final protocol in three independent runs. Both high sensitivity (80%) and high specificity (78%) were achieved, and the statistical probability of correct classifications was high, so that the test is now regarded ready for formal validation.  (+info)

Essential oils from sweet basil (Ocimum basilicum) as novel enhancers to accelerate transdermal drug delivery. (6/45)

The purpose of this study was to evaluate the essential oils from sweet basil (Ocimum basilicum, OB) as skin permeation enhancers to promote the percutaneous absorption of drugs. The in vitro and in vivo irritancy of the essential oils was also examined. Terpenes with various carbon numbers (mono-, sesqui-, di-, and tri-) were identified in both the lower-polarity fraction (OB-1) and higher-polarity fraction (OB-2). In vitro skin permeation and deposition of indomethacin were significantly enhanced after treatment with OB essential oils. The enhancing effect of OB-1 was greater than that of OB-2 in the in vitro permeation and in vivo cutaneous microdialysis analyses as well as in the plasma concentration of indomethacin. On the other hand, the in vivo study showed that OB-2 had a greater ability to retain the drug within the skin than did OB-1. Enhancement of the skin permeation of drugs by OB essential oils might be mainly due to improvement in the partitioning of the drugs to the stratum corneum. Both in vitro cell cultures (keratinocytes and skin fibroblasts) and in vivo transepidermal water loss showed no or only negligible irritation to skin by OB essential oils.  (+info)

T cell-specific inactivation of the interleukin 10 gene in mice results in enhanced T cell responses but normal innate responses to lipopolysaccharide or skin irritation. (7/45)

Interleukin (IL)-10 is a regulator of inflammatory responses and is secreted by a variety of different cell types including T cells. T regulatory cells have been shown to suppress immune responses by IL-10-dependent, but also IL-10-independent, mechanisms. Herein, we address the role of T cell-derived IL-10 in mice with an inactivation of the IL-10 gene restricted to T cells generated by Cre/loxP-mediated targeting of the IL-10 gene. Splenocytes from this T cell-specific mutant secrete increased amounts of proinflammatory cytokines after activation in vitro compared with show enhanced contact hypersensitivity reactions, and succumb to severe immunopathology upon infection with Toxoplasma gondii. Despite intact IL-10 genes in other cell types, the dysregulation of T cell responses observed in the T cell-specific IL-10 mutant closely resembles the phenotype in complete IL-10 deficiency. However, in contrast to complete IL-10 deficiency, sensitivity to endotoxic shock and irritant responses of the skin are not enhanced in the T cell-specific IL-10 mutant. Our data highlight the importance of T cell-derived IL-10 in the regulation of T cell responses and demonstrate that endotoxic shock and the irritant response of the skin are controlled by IL-10 from other cell types.  (+info)

Toxicity of some phenolic derivatives--in vitro studies. (8/45)

Cytotoxicity of 5 phenol derivatives (phenol, catechol, resorcinol, hydroquinone and phloroglucinol) was tested using a mouse 3T3 fibroblast cell line. Its relationships with structural and physicochemical properties were investigated. Linear regression analysis and Pearson's correlation coefficient were used to characterise the relationship between cytotoxicity (expressed by IC(50) values) and physicochemical parameters of compounds or their toxicity in vivo expressed by LD(50) values. The studies showed that physicochemical properties of compounds seemed to have less influence on their cytotoxic potency than structural properties. Cytotoxicity of the compounds probably depends on the number of -OH groups and their location in the aromatic ring more than on physicochemical properties of compounds. The best correlation was obtained for IC(50) values and LD(50) values determined following rabbit skin administration and experimental skin irritation score.  (+info)

The European Centre for the Validation of Alternative Methods (ECVAM) is currently supporting formal validation studies of in vitro tests for predicting skin irritancy and corrosivity, including tests employing two human skin models, EPISKINTM and EpiDermTM. When skin models are used to evaluate skin irritancy, it is important that suitable chemical application procedures are used. We evaluated the skin irritancy of 44 chemicals using the postincubation method (10-minutes treatment and 18-hours post-treatment incubation) that we originally developed to predict skin irritancy which is similar to a refined protocol for EPISKINTM proposed in an ECVAM validation study. The sensitivity, specificity, and accuracy obtained with the MTT reduction assay-based prediction model were 77.8%, 76.9%, and 77.3%, respectively while the corresponding values obtained with the interleukin-1α secretion assay-based prediction model were 61.1%, 92.3%, and 79.5%, respectively. Combining these endpoints indicated a ...

Alternatives to animal testing are the development and implementation of test methods that avoid the use of live animals. There is widespread agreement that a reduction in the number of animals used and the refinement of testing to reduce suffering should be important goals for the industries involved. Two major alternatives to in vivo animal testing are in vitro cell culture techniques and in silico computer simulation. However, some claim they are not true alternatives because simulations use data from prior animal experiments and cell cultures often require animal derived products, such as serum or cells. Others say that they cannot replace animals completely as they are unlikely to ever provide enough information about the complex interactions of living systems. Other alternatives include the use of humans for skin irritancy tests and donated human blood for pyrogenicity studies. Another alternative is so-called microdosing, in which the basic behaviour of drugs is assessed using human ...

Dermal irritation testing is conducted using the ET-50 method (time of exposure needed for a test article to reduce the viability to 50% of control tissues) and the EpiDerm tissue model. This model consists of normal (non-cancerous), human cell-derived epidermal keratinocytes cultured to form a multilayered model of the human epidermidis. The dermal irritation evaluation used at BioScience Laboratories involves applying neat test articles to the EpiDerm tissue model. This test method closely approximates the responses to product exposure exhibited by its in-vivo counterpart, the Human Repeat-Insult Patch Testing. Based on the ET-50 and comparison to benchmark materials, the degree of dermal irritancy can be estimated. An additional benefit of dermal irritation testing is that, in many instances, results obtained using animal-based testing do not correlate well with the actual response seen in human tissue.. ...
Dermatotoxicologists have to protect workers and consumers from chemicals and consumer products that have the potential to i) irritate the skin or the eyes (irritation), ii) elicit toxic responses in combination with UV-light (phototoxicity), iii) corrode the skin (irreversible damage) or iv) sensitise the skin (caused by immunological mechanisms).. Traditionally these tests have been carried out in animals. Critics point out that the results have a limited predictive value for humans, and oppose the suffering involved in these in vivo tests (e.g. the Draize test for skin irritation). Recent advances in our understanding of skin biology have resulted in the development of in vitro tests using cell cultures, skin excised from rat, pig or humans, and reconstructed human skin models. International acceptance of animal-free approaches is high for the detection of severe acute irritants, of phototoxic compounds and of corrosives using a sequential testing strategy with a weight-of-the-evidence ...

the greater the absorption. Metabolism and distribution studies showed expected pathways and distribution. Consistent with these data, acute oral studies showed oxalate-induced renal calculi, an increase in renal oxalate, and nephrotoxic effects. No systemic effects were seen with dermal application, but irritation at the site of application was produced. While many studies were performed to evaluate AHA-induced skin irritation, it was common for either the AHA concentration or the pH of the formulation to be omitted, limiting the usefulness of the data. Clinical testing using AHA formulations of known concentration and pH was done to address the issue of skin irritation as a function of concentration and pH. Skin irritation increased with AHA concentration at a given pH. Skin irritation increased when the pH of a given AHA concentration was lowered. Repeat insult patch tests using lotions and creams containing up to 10% Glycolic Acid or Lactic Acid were negative. Glycolic Acid at concentrations ...

To be able to talk about stem cells and genes on its Novagen range, Henkel has been quite smart, avoiding potential problems of ethics or sincerity : the link between Novagen products efficiency and genes and stem cells is quite indirect.. - the only place where it is talked about genes is in the name of the range, Novagen.. - on the pack, there is a statement on the role of stem cells in the epiderm : Stem cells - youth source of the skin : it is known that stem cells are the youth source of the epiderm. Indeed, in a young skin, the good activity of stem cells promotes new cells production and allows the skin to regenerates permanently. With time, stem cells activity is reduced and the skin renewal is slowed down. Result ...
Gastroesophageal reflux disease (GERD) is a disease with multifactorial etiopathogenesis, in which the genetic predisposition of an individual also plays a role.

CIR Safety Review: The CIR Expert Panel noted that the Octoxynols are chemically similar to Nonoxynols, the safety of which were previously reviewed. Long-chain Nonoxynols (9 and above) were considered safe as used, whereas short-chain Nonoxynols (8 and below) were considered safe as used in rinse-off products and safe at concentrations less than 5% in leave-on formulations. Acute exposure to Octoxynol-9 by bronchopulmonary lavage produced pneumonia, pulmonary edema, and intra-alveolar hemorrhage. No significant effects were noted in short-term oral studies of Octoxynol-9, in subchronic oral studies of Octoxynol-40, or in chronic oral studies of Octoxynol-40.. In skin irritation studies, Octoxynols ranged from nonirritating to moderately irritating. Octoxynols were not eye irritants in one study, but in others some eye irritation was observed. The Octoxynols were not mutagenic. Dermal exposure at three dose levels to Octoxynol-9 failed to induce any developmenta effects. No reproductive toxicity ...

Assessment of eye irritation hazard has long been a core requirement in any chemical legislation. Nevertheless, publications focussing on the eye damaging potential of nanomaterials are scarce. Traditionally, eye irritation testing was performed using rabbits. The OECD Test Guideline 437 Bovine Corneal Opacity and Permeability (BCOP) test method allows determining severely irritating substances without animals, and the recently adopted OECD Test Guideline 492 Reconstructed human cornea-like epithelium test method allows identifying chemicals that neither induce eye irritation nor serious eye damage. For substances applicable to these tests, huge progress has been made in replacing animal testing. The in vitro eye irritation potential of 20 nanosized and 3 non-nanosized materials was investigated in a 2-tier EpiOcular™ Eye Irritation Test (EpiOcular™-EIT) and BCOP testing strategy including histopathology of the bovine corneas. Furthermore, applicability of the testing strategy for nanomaterials was

Sensitive skin is a common skin condition that has a low tolerance to various stimuli, most commonly to applications of anything topically such as creams and moisturisers to the skins surface. If you have a sensitive skin you will usually be quoted saying I can only use Cetaphil on my skin. Sensitive skin is commonly a reactive skin condition that produces inflammation, redness and has an impaired barrier.. Skin that is sensitive may also be allergy prone and usally appears if you are prone to eczema, asthma and or rosacea. If your skin is sensitive it will most likely be dehydrated, this is because it doesnt have a well functioning protective barrier to retain and hold moisture. The dehydration (lack of water) can then contribute to and assasabate your sensitive skin even more. Often a sensitive skin is asscociated with low immunity, caused from lifestyle choices, stress, and a general low well being. It can also be genetic and you may have a predisposition if your Mother or Father suffer ...

The researchers then used simulated human skin to perform several more experiments. This simulated skin - a three-dimensional model made of living skin cells - includes all the major layers and structures of skin tissue, with the exception of hair follicles and sweat glands. The model skin could also be used in skin irritation tests required by the Food and Drug Administration for the approval of new cosmetic products, Cao said.. This system allowed us to test a range of aging symptoms that we cant replicate in cultured cells alone, Cao said. Most surprisingly, we saw that model skin treated with methylene blue retained more water and increased in thickness-both of which are features typical of younger skin.. Formulating cosmetics. The researchers also used the model skin to test the safety of cosmetic creams with methylene blue added. The results suggest that methylene blue causes little to no irritation, even at high concentrations. Encouraged by these results, Cao and colleagues hope to ...
The reconstructed human epidermis ET50 method is a powerful tool for assessing the mildness of cosmetic ingredients or formulations in contact with the skin. Using an adaptation of a regulatory skin irritation test, subtle differences between mild and ultra-mild formulations can be measured, allowing a series of products to be placed into rank order of irritation potential (and therefore mildness). It provides a quick and cost-effective pre-screen, prior to human volunteer studies, driving key decisions in formulation development and providing valuable comparisons with industry benchmark products.. The test is commonly used to assess new baby formulations such as shampoos, foam baths and body washes, providing critical insights into the mildness of the product and comparisons with leading brands. It is highly relevant for a wide variety of other formulation types including facial soaps, cleansers and other skincare items.. The ET50 test also applies to cosmetic ingredients, such as assessment of ...

This Test Guideline describes a method to estimate the developmental toxicity of a test chemical to the dung dwelling life stages of dung-dependent dipteran species. Two test species can be used. The test chemical is mixed with bovine faeces, to which either 10 eggs of Scathophaga stercoraria or 10 larvae of Musca autumnalis are added. The test will be terminated 5 days after emergence of the last adult in the control (> 18 days for S. stercoraria, >13 days for M. autumnalis). Then the possible impacts of the test chemical on the following measurement endpoints are assessed under controlled conditions: sex and total number of emerged adult flies, retardation of emergence indicated by the developmental rate and morphological change. Depending on the experimental design, the No Observed Effect Concentration (NOEC) or the Effect concentration for x percent effect (ECx) can be determined. This Guideline can be used for water soluble or insoluble substances, but is not
Skin irritation Reference Heppenheimer (2010) is considered as the key study for skin irritation and will be used for classification. The mean relative absorbance (% of the negative control, correlating with mean tissue viability) after 15 minutes incubation in the in vitro human skin model test (EpiSkin, according to OECD TG 439) was 95.1%. The classification criteria according to regulation (EC) 1272/2008 as skin irritant are not met, since the mean tissue viability was above the threshold for skin irritants of 50.0%. No classification required. Eye irritation The references Heppenheimer (2011) and Mallaun (2011) are considered as the key studies for severe eye irritation and will be used for classification. According to Heppenheimer (2011) the mean in vitro score after 240 minutes incubation results of the in vitro bovine corneal opacity and permeability assay (BCOP, according to OECD TG 437) was 1.79. The value was below the threshold for severe eye irritants of 55.1. The classification ...

Of those, weak digestion is the most interesting. Every acne clearing enthusiast needs an optimally functioning digestive system to 1) absorb vital acne vitamins and minerals from food, 2) prevent leaky gut syndrome, and 3) prevent an overly sensitive gut which reacts to innocent foods with random allergies that cause inflammation.. One scripture claims that guggul gum kindles agni, the digestive fire. There are few studies available on digestion, but one on mice above found that guggul gum reduced inflammation in the colon.. As for other areas of acne-related health, theres also evidence that guggul gum resin in its many forms is a decent source of antioxidants. The 1994 study on cholesterol above, the one which observed a 12.5% decrease in LDL, also observed a 33.3% decrease in overall oxidative stress. 33.3% is a pretty huge reduction in the overall quantity of free radicals floating around your bloodstream.. Guggul gum contains a wide variety of compounds as well as guggulsterone, ...
On One Hand: Historically SuccessfulAyurveda, the classical Indian healing system, has endorsed Guggul's benefits for thousands of years. Ayurvedic physicians frequently prescribe the gum resin to patients suffering from atherosclerosis, a progressive hardening of the arteries.

The present report is a part of our continuing efforts to explore the utility of the rat epidermal keratinocyte organotypic culture (ROC) as an alternative model to human skin in transdermal drug delivery and skin irritation studies of new chemical entities and formulations. The aim of the present study was to compare the stratum corneum lipid content of ROC with the corresponding material from human skin. The lipid composition was determined by thin-layer chromatography (TLC) and mass-spectrometry, and the thermal phase transitions of stratum corneum were studied by differential scanning calorimetry (DSC). All major lipid classes of the stratum corneum were present in ROC in a similar ratio as found in human stratum corneum. Compared to human skin, the level of non-hydroxyacid-sphingosine ceramide (NS) was increased in ROC, while alpha-hydroxyacid-phytosphingosine ceramide (AP) and non-hydroxyacid-phytosphingosine ceramides (NP) were absent. Also some alterations in fatty acid profiles of ROC ...
The effect of a single time exposure of SLS to the buccal mucosa of mice was compared to one application of the hapten OXA (oxazolone), evaluated by routine histology, immunohistochemistry and ELISA quantifications of cytokines. The SLS concentrations (2%, 4% and 8%) resulted in epithelial surface necrosis at 1-6 h, after 2-6 h accumulation of intra-epithelial neutrophils and at 24 h the main inflammatory cells were mononuclear. Increased concentrations of SLS gave more severe damage. CD4(+) T cells were found at 6 h and increased slightly up to 24 h and were most frequently seen at the lowest SLS dose. The CD8(+) T cells were kept at a low number during the whole 24 h observation period, but increased proportionally to the CD4(+) T cells. One application of 1% OXA did not raise the number of cells of either phenotype (2-24 h). Neither IL-2 nor IFN-γ demonstrated increased levels during the week of observation at any concentration of SLS, contrary to one application of OXA which caused ...

Aww…thats an awkward question! But the sad reality is I know quite a few people who are suffering from this problem. So, if you have that extra sensitive skin you must be careful in choosing the toilet paper brand.. If your preferred tissue is colorful that means it is not chemical free. Besides, you may be a fan of the scented toilet paper which is not chemical free either. These chemicals have the potential to cause allergy to your skin. It is advisable to avoid such tissue brands if you have sensitive skin.. Manufacturing process of toilet tissue is a complex one where involvement of various chemical substances is almost inevitable. These chemicals are used to make toilet papers soft, strong and fluffy. Expensive brands use more chemicals-so, you know what I mean; it is probably a better choice to avoid those expensive brands if you are allergic to toilet papers.. What if you are already affected by allergy? Simple, stop using the toilet paper right now. Dont just rely on different ...
