Fig. 4

The effects of tetramethylpyrazine (TMP) on the levels of creatine kinase (CK), lactate dehydrogenase (LDH), superoxide dismutase (SOD) and malondialdehyde (MDA) in the serum. a The effects of TMP on the levels of LDH in the serum were analyzed using ELISA. b The effects of TMP on the levels of CK in the serum were analyzed using ELISA. c The effects of TMP on the levels of SOD in the serum were analyzed using ELISA. d The effects of TMP on the levels of MDA in the serum were analyzed using ELISA. Control: rats pretreated with saline solution. ISO: rats pretreated with saline solution and treated with isoproterenol (ISO). ISO+Pro: rats pretreated with propranolol (Pro) and treated with ISO. ISO+TMP: rats pretreated with indicated dosage of TMP and treated with ISO.Values are expressed as means ± SD. ##p < 0.01 compared to control group; *p < 0.05, **p < 0.01 compared to ISO group
