Exacerbation of antigen-induced arthritis in inducible nitric oxide synthase-deficient mice. (1/146)

OBJECTIVE: Inhibition of nitric oxide (NO) produced by inducible NO synthase (iNOS) is suggested to be beneficial in experimental arthritis. Although NO is important for the integrity of the microcirculation, the effects of inhibition of iNOS on the synovial microcirculation are not currently known. This study investigated the synovial microcirculation and leukocyte-endothelial cell interactions in iNOS-deficient mice with antigen-induced arthritis (AIA) and compared these findings with disease severity. METHODS: Fourteen homozygous iNOS-/- and 14 iNOS+/+ mice were used. The severity of AIA was assessed by measuring knee joint swelling and by histologic scoring. The number of rolling and adherent leukocytes was quantitatively analyzed in synovial microvessels using intravital microscopy of intraarticular synovial tissue. Nitrite/nitrate concentrations were measured, and the expression of iNOS, E- and P-selectin, intercellular adhesion molecule 1, and vascular cell adhesion molecule 1 (VCAM-1) was assessed by immunohistochemistry. RESULTS: In iNOS+/+ animals with AIA, the plasma concentration of nitrite/nitrate was increased 3-fold and iNOS expression was detected in cells of the joint. Swelling of the knee joint as well as leukocyte infiltration were enhanced in the iNOS-/- arthritic animals compared with iNOS+/+ mice with AIA. AIA-associated leukocyte-endothelial cell interaction in synovial postcapillary venules was more pronounced in iNOS-/-, compared with iNOS+/+, arthritic mice. A strong expression of P-selectin and VCAM-1 was observed in the iNOS-/- arthritic mice only. CONCLUSION: These data suggest that NO production by iNOS in vivo has antiinflammatory effects in experimental arthritis, by mediating a reduction in leukocyte adhesion and infiltration.  (+info)

Matrix metalloproteinases and aggrecanases cleave aggrecan in different zones of normal cartilage but colocalize in the development of osteoarthritic lesions in STR/ort mice. (2/146)

OBJECTIVE: To map aggrecan cleavage by matrix metalloproteinases (MMPs) and aggrecanases in normal murine tibial articular cartilage (CBA strain) and in the development of spontaneous osteoarthritis (OA) in the STR/ort mouse and to assess the influence of sex hormone status on these conditions in gonadectomized STR/ort mice. METHODS: The distributions of neoepitopes of aggrecan generated by MMP (VDIPEN) and aggrecanase (NITEGE) cleavage were investigated by immunohistochemistry. RESULTS: VDIPEN neoepitope was detected mainly in the pericellular matrix of deep-zone chondrocytes in normal tibial cartilage from STR/ort and CBA mice. In early OA, VDIPEN immunostaining also localized to the pericellular matrix of chondrocytes at the site of the lesion. With increasing severity of OA lesions, VDIPEN immunostaining was also detected in the interterritorial matrix, close to the site of the lesion. In contrast, NITEGE mapped most strongly to the pericellular matrix of upper-zone chondrocytes in normal tibial cartilage. As with VDIPEN, NITEGE was strongly expressed in the pericellular matrix at the site of early OA lesions. With advancing OA, NITEGE colocalized with VDIPEN in both the pericellular and interterritorial matrices of chondrocytes adjacent to OA lesions and in those of the deep zones. Hormone status did not appear to influence the development of OA or the distribution of aggrecan neoepitopes in STR/ort mice. CONCLUSION: MMP- and aggrecanase-generated neoepitopes map predominantly to different regions in normal murine tibial cartilage. However, both groups of enzymes generate increased amounts of neoepitopes in pericellular and interterritorial matrix adjacent to histopathologic lesions of OA. Aggrecan degradation and the development of OA appear to be independent of sex hormone status in this model.  (+info)

Processing of nociceptive mechanical and thermal information in central amygdala neurons with knee-joint input. (3/146)

Pain has a strong emotional dimension, and the amygdala plays a key role in emotionality. The processing of nociceptive mechanical and thermal information was studied in individual neurons of the central nucleus of the amygdala, the target of the spino-parabrachio-amygdaloid pain pathway and a major output nucleus of the amygdala. This study is the first to characterize nociceptive amygdala neurons with input from deep tissue, particularly the knee joint. In 46 anesthetized rats, extracellular single-unit recordings were made from 119 central amygdala neurons that were activated orthodromically by electrical stimulation in the lateral pontine parabrachial area and were tested for receptive fields in the knee joints. Responses to brief mechanical stimulation of joints, muscles, and skin and to cutaneous thermal stimuli were recorded. Receptive-field sizes and thresholds were mapped and stimulus-response functions constructed. Neurons in the central nucleus of the amygdala with excitatory input from the knee joint (n = 62) typically had large symmetrical receptive fields in both hindlimbs or in all four extremities and responded exclusively or preferentially to noxious mechanical stimulation of deep tissue (n = 58). Noxious mechanical stimulation of the skin excited 30 of these neurons; noxious heat activated 21 neurons. Stimulus-response data were best fitted by a sigmoid nonlinear regression model rather than by a monotonically increasing linear function. Another 15 neurons were inhibited by noxious mechanical stimulation of the knee joint and other deep tissue. Fifteen neurons had no receptive field in the knee but responded to noxious stimulation of other body areas; 27 nonresponsive neurons were not activated by natural somesthetic stimulation. Our data suggest that excitation is the predominant effect of brief painful stimulation of somatic tissue on the population of central amygdala neurons with knee joint input. Their large symmetrical receptive fields and sigmoid rather than monotonically increasing linear stimulus-response functions suggest a role of nociceptive central amygdala neurons in other than sensory-discriminative aspects of pain.  (+info)

Complex polysaccharide inclusions in skeletal muscle adjacent to sarcomas in two dogs. (4/146)

Inclusions of periodic acid-Schiff-positive, amylase resistant material were found within skeletal muscle fibers adjacent to an osteosarcoma in the proximal femur of an 8-year-old intact female Cocker Spaniel dog (dog No. 1) and adjacent to a synovial cell sarcoma of the stifle joint in a 7-year-old spayed female Bouvier des Flandres dog (dog No. 2). Inclusions were pale blue-gray with hematoxylin and eosin stain and formed irregular inclusions, replacing up to approximately 80% of the fiber diameter. Inclusions from dog No. 2 were of non-membrane-bound granular to filamentous material that occasionally formed discrete, elongate electron-dense masses. The features of these inclusions were similar to those of materials previously described as complex polysaccharide, polyglucosan bodies, amylopectin, and Lafora bodies. Evidence for a generalized metabolic disorder was not found in these two dogs, suggesting that storage of complex polysaccharide can occur as a relatively nonspecific response to metabolic alterations in skeletal muscle in a variety of conditions.  (+info)

Differential function of nitric oxide in murine antigen-induced arthritis. (5/146)

BACKGROUND: The aim of our study was to investigate the role of inducible nitric oxide synthase (iNOS)-derived nitric oxide (NO) production in different stages of murine antigen-induced arthritis (AiA). METHODS: Clinical, histological and microcirculatory parameters (measured by intravital fluorescence microscopy) were assessed in the knee joint during acute and chronic AiA after inhibition of iNOS with L-N(6)-(1-iminoethyl)lysine (L-NIL). Plasma concentrations of and were evaluated by the Griess reaction and the expression of iNOS, P- and E-selectin, intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1) by immunohistochemistry. RESULTS: In both stages of the disease, plasma concentrations of and were increased and iNOS was expressed. In the acute phase, swelling, leucocyte adhesion, leucocyte infiltration and expression of adhesion molecules were increased in arthritic animals treated with L-NIL in comparison with untreated arthritic animals. In the chronic phase, no change in the disease parameters could be detected after L-NIL treatment. CONCLUSION: Increased NO production induced by iNOS during the acute phase of AiA can be regarded as a protective response in the prevention of further leucocytic infiltration and joint destruction, whereas it seems to play a subordinate role in chronic AiA.  (+info)

One of two chondrocyte-expressed isoforms of cartilage intermediate-layer protein functions as an insulin-like growth factor 1 antagonist. (6/146)

OBJECTIVE: Aging and osteoarthritic (OA) cartilage commonly demonstrate enhanced expression of the large, transforming growth factor beta (TGFbeta)-inducible glycoprotein cartilage intermediate-layer protein (CILP) as well as enhanced extracellular inorganic pyrophosphate (PPi) that promotes the deposition of calcium pyrophosphate dihydrate crystals. In normal chondrocytes, TGFbeta induces elevated chondrocyte extracellular PPi. Insulin-like growth factor 1 (IGF-1) normally blocks this response and reduces extracellular PPi. However, chondrocyte resistance to IGF-1 is observed in OA and aging. Because CILP was reported to chromatographically fractionate with PPi-generating nucleotide pyrophosphatase phosphodiesterase (NPP) activity, it has been broadly assumed that CILP itself has NPP activity. Our objective was to directly define CILP functions and their relationship to IGF-1 in chondrocytes. METHODS: Using primary cultures of articular chondrocytes from the knee, we defined the function of the previously described CILP (CILP-1) and of a recently described 50.6% identical protein that we designated the CILP-2 isoform. RESULTS: Both CILP isoforms were constitutively expressed by primary cultured articular chondrocytes, but only CILP-1 expression was detectable in cultured knee meniscal cartilage cells. Neither CILP isoform had intrinsic NPP activity. But CILP-1 blocked the ability of IGF-1 to decrease extracellular PPi, an activity specific for the CILP-1 N-terminal domain. The CILP-1 N-terminal domain also suppressed IGF-1-induced (but not TGFbeta-induced) proliferation and sulfated proteoglycan synthesis, and it inhibited ligand-induced IGF-1 receptor autophosphorylation. CONCLUSION: Two CILP isoforms are differentially expressed by chondrocytes. Neither CILP isoform exhibits PPi-generating NPP activity. But, increased expression of CILP-1, via N-terminal domain-mediated inhibitory effects of CILP-1 on chondrocyte IGF-1 responsiveness, could impair chondrocyte growth and matrix repair and indirectly promote PPi supersaturation in aging and OA cartilage.  (+info)

Hamstring graft technique for stabilization of canine cranial cruciate ligament deficient stifles. (7/146)

OBJECTIVE: To investigate the harvest and application of hamstring grafts for canine cranial cruciate ligament (CrCL) reconstruction. STUDY DESIGN: Experimental study. ANIMALS: Four adult female hounds, weighing 26.3 +/- 1.6 kg (mean +/- SEM). METHODS-One stifle in each dog was randomly chosen for hamstring graft CrCL reconstruction after native CrCL transection. Arthroscopy was performed to evaluate graft integrity at 12 weeks. Gait analysis and stifle radiographs were performed preoperatively and up to 52 weeks after graft placement. Dogs were killed 12 (n = 2) or 52 weeks (n = 2) after CrCL reconstruction. Tissues were evaluated grossly and with light and confocal laser microscopy. RESULTS: Hamstring grafts were intact in all stifles at 12 weeks (n = 4) and 52 weeks (n = 2). Grossly, there was no osteoarthritis in stifles at 12 weeks and only chondrophytes along the trochlear ridges at 52 weeks. Minimal radiographic evidence of osteoarthritis developed in stifles with grafts during the study. Lameness in limbs with grafts resolved by 52 weeks. Graft tissue was highly vascular, ligamentized, and undergoing active remodeling at 12 weeks. Fifty-two weeks after graft placement, intraarticular graft tissue was well vascularized, mature, and encapsulated by synovium, and graft-bone interfaces were characterized by Sharpey's fiber insertions. There was no evidence of graft necrosis using confocal laser microscopy at either time point. CONCLUSIONS: The hamstring graft technique may be a viable method of canine CrCL reconstruction. CLINICAL RELEVANCE: Hamstring grafts may be an alternative technique for canine CrCL reconstruction. Further study is needed before clinical application.  (+info)

Basic fibroblast growth factor mediates transduction of mechanical signals when articular cartilage is loaded. (8/146)

OBJECTIVE: To determine whether the basic fibroblast growth factor (bFGF) mediates signal transduction in articular cartilage in response to mechanical loading. METHODS: Articular cartilage from porcine metacarpophalangeal or knee joints was cyclically loaded (62.5-250N) for 2 minutes in the absence or presence of a bFGF receptor inhibitor, SB 402451 (250 nM). Activation of the extracellularly regulated kinase MAP kinase ERK was measured by Western blot analysis. Changes in protein synthesis were assessed by measuring the incorporation of (35)S-Met/Cys into proteins secreted by cartilage explants or by isolated chondrocytes. RESULTS: Rapid activation of the ERK MAP kinase occurred when articular cartilage was loaded. This was dependent upon release of the bFGF because it was restricted by the FGF receptor inhibitor. Loaded explants were shown to release bFGF. Loading or bFGF stimulation of explants induced synthesis and secretion of tissue inhibitor of metalloproteinases 1 (TIMP-1), which was inhibited by SB 402451. CONCLUSION: Cyclical loading of articular cartilage causes bFGF-dependent activation of ERK and synthesis of TIMP-1.  (+info)

The term "stifle" is commonly used in veterinary medicine to refer to the joint in the leg of animals, specifically the knee joint in quadrupeds such as dogs and horses. In human anatomy, this joint is called the patellofemoral joint or knee joint. The stifle is a complex joint made up of several bones, including the femur, tibia, and patella (kneecap), as well as various ligaments, tendons, and cartilage that provide stability and support. Injuries or diseases affecting the stifle can cause lameness, pain, and decreased mobility in animals.

Lameness in animals refers to an alteration in the animal's normal gait or movement, which is often caused by pain, injury, or disease affecting the locomotor system. This can include structures such as bones, joints, muscles, tendons, and ligaments. The severity of lameness can vary from subtle to non-weight bearing, and it can affect one or more limbs.

Lameness can have various causes, including trauma, infection, degenerative diseases, congenital defects, and neurological disorders. In order to diagnose and treat lameness in animals, a veterinarian will typically perform a physical examination, observe the animal's gait and movement, and may use diagnostic imaging techniques such as X-rays or ultrasound to identify the underlying cause. Treatment for lameness can include medication, rest, physical therapy, surgery, or a combination of these approaches.

The Anterior Cruciate Ligament (ACL) is a major stabilizing ligament in the knee. It is one of the four strong bands of tissue that connect the bones of the knee joint together. The ACL runs diagonally through the middle of the knee and helps to control the back and forth motion of the knee, as well as provide stability to the knee joint. Injuries to the ACL often occur during sports or physical activities that involve sudden stops, changes in direction, or awkward landings.

Osteochondritis is a joint condition where a piece of cartilage or bone in the joint separates from its attachment due to a lack of blood supply. This can cause pain, stiffness, and potentially restricted movement in the affected joint. It often occurs in weight-bearing joints like the knee or ankle, and is more common in children and adolescents. The separated piece may sometimes float around in the joint space, causing further damage to the cartilage and bone. If left untreated, it can lead to long-term joint problems. Also known as osteochondrosis or osteochondritis dissecans.

There is no medical definition for "dog diseases" as it is too broad a term. However, dogs can suffer from various health conditions and illnesses that are specific to their species or similar to those found in humans. Some common categories of dog diseases include:

1. Infectious Diseases: These are caused by viruses, bacteria, fungi, or parasites. Examples include distemper, parvovirus, kennel cough, Lyme disease, and heartworms.
2. Hereditary/Genetic Disorders: Some dogs may inherit certain genetic disorders from their parents. Examples include hip dysplasia, elbow dysplasia, progressive retinal atrophy (PRA), and degenerative myelopathy.
3. Age-Related Diseases: As dogs age, they become more susceptible to various health issues. Common age-related diseases in dogs include arthritis, dental disease, cancer, and cognitive dysfunction syndrome (CDS).
4. Nutritional Disorders: Malnutrition or improper feeding can lead to various health problems in dogs. Examples include obesity, malnutrition, and vitamin deficiencies.
5. Environmental Diseases: These are caused by exposure to environmental factors such as toxins, allergens, or extreme temperatures. Examples include heatstroke, frostbite, and toxicities from ingesting harmful substances.
6. Neurological Disorders: Dogs can suffer from various neurological conditions that affect their nervous system. Examples include epilepsy, intervertebral disc disease (IVDD), and vestibular disease.
7. Behavioral Disorders: Some dogs may develop behavioral issues due to various factors such as anxiety, fear, or aggression. Examples include separation anxiety, noise phobias, and resource guarding.

It's important to note that regular veterinary care, proper nutrition, exercise, and preventative measures can help reduce the risk of many dog diseases.

I believe there might be a misunderstanding in your question. "Dogs" is not a medical term or condition. It is the common name for a domesticated carnivore of the family Canidae, specifically the genus Canis, which includes wolves, foxes, and other extant and extinct species of mammals. Dogs are often kept as pets and companions, and they have been bred in a wide variety of forms and sizes for different purposes, such as hunting, herding, guarding, assisting police and military forces, and providing companionship and emotional support.

If you meant to ask about a specific medical condition or term related to dogs, please provide more context so I can give you an accurate answer.

Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. It provides a cushion between bones and allows for smooth movement by reducing friction. Articular cartilage also absorbs shock and distributes loads evenly across the joint, protecting the bones from damage. It is avascular, meaning it does not have its own blood supply, and relies on the surrounding synovial fluid for nutrients. Over time, articular cartilage can wear down or become damaged due to injury or disease, leading to conditions such as osteoarthritis.

A hindlimb, also known as a posterior limb, is one of the pair of extremities that are located distally to the trunk in tetrapods (four-legged vertebrates) and include mammals, birds, reptiles, and amphibians. In humans and other primates, hindlimbs are equivalent to the lower limbs, which consist of the thigh, leg, foot, and toes.

The primary function of hindlimbs is locomotion, allowing animals to move from one place to another. However, they also play a role in other activities such as balance, support, and communication. In humans, the hindlimbs are responsible for weight-bearing, standing, walking, running, and jumping.

In medical terminology, the term "hindlimb" is not commonly used to describe human anatomy. Instead, healthcare professionals use terms like lower limbs or lower extremities to refer to the same region of the body. However, in comparative anatomy and veterinary medicine, the term hindlimb is still widely used to describe the corresponding structures in non-human animals.

Osteoarthritis (OA) is a type of joint disease that is characterized by the breakdown and eventual loss of cartilage - the tissue that cushions the ends of bones where they meet in the joints. This breakdown can cause the bones to rub against each other, causing pain, stiffness, and loss of mobility. OA can occur in any joint, but it most commonly affects the hands, knees, hips, and spine. It is often associated with aging and can be caused or worsened by obesity, injury, or overuse.

The medical definition of osteoarthritis is: "a degenerative, non-inflammatory joint disease characterized by the loss of articular cartilage, bone remodeling, and the formation of osteophytes (bone spurs). It is often associated with pain, stiffness, and decreased range of motion in the affected joint."

Joint diseases is a broad term that refers to various conditions affecting the joints, including but not limited to:

1. Osteoarthritis (OA): A degenerative joint disease characterized by the breakdown of cartilage and underlying bone, leading to pain, stiffness, and potential loss of function.
2. Rheumatoid Arthritis (RA): An autoimmune disorder causing inflammation in the synovial membrane lining the joints, resulting in swelling, pain, and joint damage if left untreated.
3. Infectious Arthritis: Joint inflammation caused by bacterial, viral, or fungal infections that spread through the bloodstream or directly enter the joint space.
4. Gout: A type of arthritis resulting from the buildup of uric acid crystals in the joints, typically affecting the big toe and characterized by sudden attacks of severe pain, redness, and swelling.
5. Psoriatic Arthritis (PsA): An inflammatory joint disease associated with psoriasis, causing symptoms such as pain, stiffness, and swelling in the joints and surrounding tissues.
6. Juvenile Idiopathic Arthritis (JIA): A group of chronic arthritis conditions affecting children, characterized by joint inflammation, pain, and stiffness.
7. Ankylosing Spondylitis: A form of arthritis primarily affecting the spine, causing inflammation, pain, and potential fusion of spinal vertebrae.
8. Bursitis: Inflammation of the fluid-filled sacs (bursae) that cushion joints, leading to pain and swelling.
9. Tendinitis: Inflammation or degeneration of tendons, which connect muscles to bones, often resulting in pain and stiffness near joints.

These conditions can impact the function and mobility of affected joints, causing discomfort and limiting daily activities. Proper diagnosis and treatment are essential for managing joint diseases and preserving joint health.

Osteochondrosis is a group of orthopedic disorders that primarily affect the epiphyseal growth plates (the areas of growing tissue at the ends of long bones) and adjacent articular (joint) cartilage in children and adolescents. These disorders are characterized by abnormal development, degeneration, or fragmentation of the affected bone and/or cartilage, which can lead to pain, stiffness, and, in some cases, restricted mobility.

The term "osteochondrosis" is often used interchangeably with "osteochondritis dissecans," but they are not identical conditions. Osteochondrosis refers to the general category of disorders, while osteochondritis dissecans is a specific type of osteochondrosis that primarily affects the subchondral bone (the layer of bone directly beneath the articular cartilage) and results in the formation of loose fragments or "joint mice."

Examples of osteochondrosis include:

1. Legg-Calvé-Perthes disease, which affects the hip joint
2. Köhler's disease, which affects the navicular bone in the foot
3. Panner's disease, which affects the elbow joint
4. Scheuermann's disease, which affects the vertebral bodies in the spine
5. Freiberg's infarction, which affects the metatarsal heads in the foot

The exact cause of osteochondrosis remains unclear, but it is believed to involve a combination of genetic, biomechanical, and environmental factors that contribute to the abnormal growth and development of the affected bone and cartilage. Treatment typically involves rest, physical therapy, bracing or casting, and, in some cases, surgery to remove loose fragments or promote healing.

The knee joint, also known as the tibiofemoral joint, is the largest and one of the most complex joints in the human body. It is a synovial joint that connects the thighbone (femur) to the shinbone (tibia). The patella (kneecap), which is a sesamoid bone, is located in front of the knee joint and helps in the extension of the leg.

The knee joint is made up of three articulations: the femorotibial joint between the femur and tibia, the femoropatellar joint between the femur and patella, and the tibiofibular joint between the tibia and fibula. These articulations are surrounded by a fibrous capsule that encloses the synovial membrane, which secretes synovial fluid to lubricate the joint.

The knee joint is stabilized by several ligaments, including the medial and lateral collateral ligaments, which provide stability to the sides of the joint, and the anterior and posterior cruciate ligaments, which prevent excessive forward and backward movement of the tibia relative to the femur. The menisci, which are C-shaped fibrocartilaginous structures located between the femoral condyles and tibial plateaus, also help to stabilize the joint by absorbing shock and distributing weight evenly across the articular surfaces.

The knee joint allows for flexion, extension, and a small amount of rotation, making it essential for activities such as walking, running, jumping, and sitting.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

The tibia, also known as the shin bone, is the larger of the two bones in the lower leg and part of the knee joint. It supports most of the body's weight and is a major insertion point for muscles that flex the foot and bend the leg. The tibia articulates with the femur at the knee joint and with the fibula and talus bone at the ankle joint. Injuries to the tibia, such as fractures, are common in sports and other activities that put stress on the lower leg.
