ABSTRACT
Objective To evaluate the prevention of glucocorticoid -induced avascular necrosis of the femoral head(ANFH)with Tongluo Shenggu Capsule(TSC).Methods One hundred and twenty adult SD rats were randomized into six groups:normal control group,model group,clofibratum group and three -dose TSC groups(high -,moderate -and low -dose respectively).ANFH rat models were established by injection of glucocorticoid once per week and the med-ication groups were given drugs by ga stric infusion one time a day.The rats were killed in the fourth,eighth and twelfth week respectively.Then the macrosc opic and microscopic feature of the f emoral head were observed,and ink -p erfused specimens of the femoral head were detected and analyzed by auto -photograph software of Metamoph to evaluate the pre-ventive effect of TSC.Results In TSC groups,bone trabecula grew we ll,similar to the normal group;lacu nar bone per-centage was lower than that in the mod el group;fatty degeneration in marrow cavity of the femoral head was redu ced,andthe number of subcartilaginous bloo d vessels and their diameter were increased as compared with those in the model group(P
ABSTRACT
Objective To determinate the content of Danshensu in Xingkenin g Capsules by HPLC.Methods HPLC with Hypersil ODS2 column was used, MeOH- 1 % acetic acid( 12:88) as a mobile phase and detection wavelength at 280nm.Re sults The linear range of Danshensu was in the range of 0.256～ 1.278 ? g. Th e average recovery of Danshensu was 102.73 % with a RSD of 1.34 % .Conclusio n The method is simple with a good reproducibility and can be used for the qu ality control of Xingkening Capsules.
