Comparison of LDH, CK, and NEFA activity in serum of ISO-induced MI rats administrated different combinations. TGS: total ginsenosides, RPG: the remainder of PG (mainly containing panaxan, TGS removed), TSA: total salvianolic acids, RSM: the remainder of SM (mainly containing diterpenoid quinones, TSA removed). *P < 0.05, **P < 0.01 vs model group. Positive control drug: compound danshen pills. Details of the experimental procedures are given in Materials and Methods.
