Effects of oral administration of type Ⅱ collagen on adjuvant arthritis in rat sand its mechanisms

Objective To investigate the effects of oral administration of type Ⅱ collagen (CⅡ) on a djuvant arthritis (AA) in rats and its mechanisms, and to compare the effects of CⅡ with those of the Chinese traditional medicine Tripterygium Polyglycoside a dministered similarly.Methods Arthritis was induced in rats by immunization using Freund's complete adjuvant (FCA). After feeding rats either soluble CⅡ or Tripterygium Polyglycoside, chan ges in degree of articular swelling and articular histological findings were observed in AA rats. Some correlative immunological indexes were measured, includi ng delayed type hypersensitivity (DTH) reaction, anti-collagen and anti-Mycoba cterium tuberculosis (MT) antibody in serum, and levels of IFN-γ and TNF-α i n articular steep in rats.Results Oral administration of CⅡ was able to alleviate both distinctly articular and general symptoms in AA rats, suppress synovium hyperplasia and inflammatory cells infiltration in arthrosis capsule. The effects brought about by CⅡ were stronger than those by Tripterygium Polyglycoside. Oral administration of CⅡ inhibi ted antigen-specific immune response, such as DTH and antibody reaction to CⅡ . In addition, the expression of IFN-γ and TNF-α in joints were locally dow nregulated. Conclusions The therapeutic effect of oral administration of CⅡ is obvious on adjuvant art hritis in rats. Its remedial mechanisms are likely related to the downregulation of both IFN-γ and TNF-α, and the suppression of cell immunity.     

Effect of electro-acupuncture on rat joint pathomorphology of chronic adjuvant arthritis model

Objective:To study the effect of electro-acupuncture (EA) on pathomorphological changes of joints in rat model of chronic adjuvant arthritis.Methods: The rat chronic adjuvant arthritis model was established by subcutaneous injection of 0.1 ml of complete Freund’s adjuvant to the left hind sole. Forty Wistar rats were randomly divided into the model group, the low frequency (2 Hz) EA group, the high frequency EA (100 Hz) group and the body acupuncture group. After being modeled except the model group, the other three groups were treated with EA or body acupuncture in Yanglingquan points (bilateral) for 3 weeks, the left ankle joints and metatarsal joints of rats were taken for pathological examination by fixing with 10% formalin and embedding in paraffin, sectioning and staining with HE.Results: Obvious inflammatory cell infiltration, loosened synovial tissue, damage of articular cartilage and proliferation of synovial cells and granulation tissue were observed in the sections of joints in model rats. These pathological changes were significantly improved after treatment, and the effect in the high frequency EA group were significantly superior to that in the low frequency EA and body acupuncture group.Conclusion: High frequency EA could significantly improve the pathomorphological changes of joints in chronic adjuvant arthritis rat models.

Effects and mechanisms of Cryptotanshinone on rats with adjuvant arthritis

Background  Cryptotanshinone (CT) is the major active constituent of Salvia miltiorrhiza Bunge. The present study was carried out to investigate the effects of CT on rats with adjuvant arthritis (AA).

Methods  AA was induced by the metatarsal footpad injection with complete Freund’s adjuvant in male Sprague-Dawley rats. The secondary inflammatory reaction was evaluated by hind paw swelling and the polyarthritis index. Activity of interleukin-1 (IL-1) was detected by the concanavalin A-induced thymocytes proliferation assay. The lymphocytes proliferation and IL-2 production were assayed by 3-(4,5-2dimethylthiazal-2yl)2,5-diphenyltetrazoliumbromide (MTT) and activated mouse splenocytes proliferation, respectively.

Results  Intragastric administration of CT (50 and 100 mg/kg) significantly decreased secondary inflammatory reactions and increased the spleen and thymus index. There was a marked immunologic and inflammatory response in the AA model, which was accompanied by the decrease of thymocyte proliferation and IL-2 production as well as the increase of IL-1 production. CT apparently enhanced thymocyte proliferation and decreased IL-1 production in AA rats.

Conclusion  These results indicate that CT may exert its anti-inflammatory and immunoregulatory effects through inhibiting lymphocyte proliferation and production of pro-inflammatory mediators.
