The effects of Compound Salvia Injection (CSI) on plasma lipid peroxidation (LPO)

RBC superoxide dismutase (SOD)

glutathione peroxidase (GSH-Px) and catalase (CAT) activity in patients with chronic cor pulmonale were studied. Thirty patients were randomly divided into two groups: the group treated with routine therapy (routine group) and the group treated with routine therapy plus CSI (CSI group). The 4 parameters mentioned above have been measured in patients of the two groups and in 22 healthy subjects for control. The results showed: (1) Before treatment

both the treatment groups had significantly higher LPO and SOD and markedly lower GSH-Px and CAT level than those of the healthy control (P<0.001). (2) After treatment the 4 parameters have been normalized in CSI group. (3) In the routine group

the parameters were still abnormal

that is

the increased levels of GSH-Px and CAT and the decreased LPO were singificantly greater in CSI group than that in routine group. These results indicated that CSI could obviously lower the enhanced lipid peroxidation and adjust the imbalance of antioxidant enzymes.
