Effect of Saussurea involucrata Injection on Counteracting Adjuvant-induced Arthritis and Its Immunoregulation Function / 中药新药与临床药理

ABSTRACT

Objective To investigate the effect of Saussurea involucrata Injection(SII)on counteracting adjuvant-induced arthritis and its immunoregulation function,thus to supply the pharmacological evidences for the clinical treatment of arthritis.Methods Adjuvant arthritis was induced by plantar injection of Freundi' s complete adjuvant.MTT method was used to detect T and B lymphocytes proliferation,and sheep red blood cell immunization was used for hemolysin determination.Results(1)Rats right posterior metatarsus which was injected adjuvant was swollen from the second day to the 22nd day(the primary injury),and left posterior metatarsus not receiving adjuvant injection was swollen from the sixth day to the 20 th day(the secondary lesion).The differences of swelling degree were significant between SII group and NS group.(2)Consecutive intramuscular injection of SII 0.2,0.4,0.8 mL? kg-1? d-1 for 22 days suppressed the primary injury and the secondary lesion of adjuvant arthritis in rats,relieved swelling significantly from the sixth day(P
