RESUMEN

Aim To study the effect of Taurochenodeoxycholic Acid (TCDCA) on immunologic cell in vitro and in vivo in mice. Methods Five doses were used , including 0.043, 0.065, 0.1, 0.153, 0.189 g?kg-1 in vivo and 0.01, 0.05, 0.1, 1, 10 mg?L-1 in vitro. Effects of TCDCA on peritoneal macrophage in mouse in vitro,splenic lymphocyte, normal organism, immunologic functional inhibiting model and nerve-endocrine-immunoregulation system were investigated. Results TCDCA had the obvious immunoregulation effect on normal organisms in mouse. 0.1 g?kg-1 TCDCA had the obvious anastated effects on the immunological inhibiting model made up by the cyclosporine A and cyclophosphamide. TCDCA may affect the peritoneal macrophage and splenic lymphocyte in vitro directly, meanwhile two kinds of immunological cells showed the obvious immunoregulation effects on the whole. 0.1 g?kg-1 TCDCA can increase the hydrocortisone contents of the nerve-endocrine-immunoregulation system in mouse most remarkably. Conclusion TCDCA had the adjustment effect on the immunoregulation function in mouse.
