Abstract:
Objective:To investigate the effects of Chinese medicine prescriptions Gancaofuzi-tang and Tongbi-fang on adjusting the dynamic expression of related cytokines and further ameliorating the histopathology of synovitis in rats with Ⅱ collagen induced arthritis(CIA).Methods:The experimental Wistar rat model of CIA was set up successfully.The rats divided into five groups in random: normal(N),Gancaofuzi-tang treatment(GF),Tongbi-fang treatment(TB),Puwei western medicine treatment(PW) and model control(C).The different medicine was affused into stomach 1.5 ml/rat,once daily.The rats were sacrificed after 6 weeks of medicine administration.Foot swelling degrees of the rats were measured every other day,and then calculate swelling rates.Getting blood after 3 weeks of treatment from rat's innercanthus to detect the level of serum Sialic Acid(SA) and the level of serum IL-2 and TNF-? by ELISA.The synovial histopathology was observed with HE staining under optical microscope.Results:Gancaofuzi-tang and Tongbi-fang significantly decreased swelling rate of joints in CIA rats.The pathology of synovisl tissues was markedly ameliorated.After administration for 3 weeks,the levels of serum SA,IL-2 and TNF-? of the rats in GF and TB groups were significantly decreased compared with the control.Continuous administration for 6 weeks,the levels of the targets in GF and TB rats reached to near the normal level.Conclusion:All the results demonstrate that Gancaofuzi-tang and Tongbi-fang play anti-inflammatory and immunoregulatory roles in CIA rats through inhibiting activation of some inflammatory mediators,adjusting related cytokines expression,then eliminating the joint swelling and improving synovitis pathology,which might be looked as immune suppression effects similar to NSAID medicine.
