Objective: The present study was designed to investigate the antiarthritic activity of methanolic stem extract of Tecoma stans in wistar albino rats using in vitro albumin denaturation method and in vivo models like complete freunds adjuvant (CFA) induced arthritis and egg albumin induced arthritic models. Acute toxicity studies were carried out and the extract was found to be safe upto 2000 mg...

The role of cytokines in health and disease has received increasing attention and numerous investigations have explored the regulation of cytokine gene expression. Tumor necrosis factor-alpha (TNF) has received particular attention because of its central role in septic shock and more recent work has shown its participation in transplant immunology. We explored the mechanism of cyclosporine A (C...

introduction: immune system is involved in the etiology and pathophysiology of inflammation and vitamins are important sources of substances inducing nonspecific immunomodulatory effects. given the proinflammatory role of cytokines in the inflammation and pain induction, this study aimed to assess the effects of long-term administration of vitamin b1 on the proinflammatory cytokines, edema, and...

Experimental autoimmune vitiligo was induced by the intradermal injection of the purified mushroom tyrosinase emulsified in Complete Freunds Adjuvant (CFA) in female C57BL/6 mice. The onset of vitiligo was characterized by hair hypopigmentation and total melanocyte depletion in the basal layer of the epidermis. Oral administration of semipurified mushroom tyrosinase prevented experimental autoi...

BACKGROUND Safe and effective treatment for chronic inflammatory and neuropathic pain remains a key unmet medical need for many patients. The recent discovery and description of the transient receptor potential family of receptors including TRPV1 and TRPA1 has provided a number of potential new therapeutic targets for treating chronic pain. Recent reports have suggested that TRPA1 may play an i...

BACKGROUND: Immunity against the T cell receptor (TCR) is considered to play a central role in the regulation of experimental allergic encephalomyelitis (EAE), a model system of autoimmune disease characterized by a restricted usage of TCR genes. Methods of specific vaccination against the TCR of pathogenetic T cells have included attenuated T cells and synthetic peptides from the sequence of t...

Central neuropathic pain (CNP) is considered as a complicated sensory disturbance which many multiple sclerosis (MS) patients suffer from. Although monophasic experimental autoimmune encephalomyelitis (EAE) mouse model is a gold standard model in preclinical research of MS, severe movement deficit could confound pain behaviors evaluation over the disease course. In this study, complete Freund&r...

Daily treatment with cyclosporin at a dose of 25 mg/kg for 14 d gave complete suppression of the development of collagen arthritis and adjuvant arthritis in Sprague-Dawley rats during an observation period of 45 d. To study whether the immunologic unresponsiveness produced by cyclosporin is antigen specific, we rechallenged the cyclosporin-protected rats with either type II collagen or complete...

background : pain is one of the main protests of inflammatory diseases, hence, understanding the mechanisms which involved in the induction and persistence of pain is essential. microglia is a contributing factor in the onset and maintenance of inflammation. increased microglial   activation increases the level of central pro-inflammatory cytokines and the development of central sensitization f...
