Fig. 2From: Tetramethylpyrazine exerts a protective effect against injury from acute myocardial ischemia by regulating the PI3K/Akt/GSK-3β signaling pathwayStatistical analysis of tetramethylpyrazine (TMP) on ST segment elevation. Values are expressed as means ± SD. ##p < 0.01 compared to control, **p < 0.01 compared to ISO group. 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 ISOBack to article page
