BACKGROUND: Lanceolata and astragalus can improve myocardial ischemia, which are widely used in clinics.OBJECTIVE: To compare the effects of extract of lanceolata and astragalus on electrocardiogram (ECG) of rats with experimental myocardial ischernia.DESIGN: Completely randomized and controlled study.SETTING: Pharmacological College of Harbin Commerce University.MATERIALS: The experiment was carried out at the Laboratory of Pharmacological College of Harbin Commerce University from September to December 2002. Totally 30 healthy adult Wistar rats were divided randomly into 3 groups: control group, lanceolata group and astragalus group with 10 in each group.METHODS: ① After anesthesia, lead ECG Ⅱ of rats was recorded.30 g/kg saline, 30 g/kg lanceolata extract and 30 g/kg astragalus extract [extract of lanceolata and astragalus (raw drug: 1 g/mL)] were injected into rats in the control group, lanceolata group and astragalus group respectively. After 1-3 minutes, 0.5 U/kg pituitrin was injected intravenously (for model of myocardial ischemia), and then saline was used to dilute from 0.1to 0.2 mL for 10-second injection. Changes of ECG after injection of pituitrin were recorded with LMA-2B Ⅱ physiological recorder (migration of T wave and ST section and change of heart rate). ② Differences of data were compared with t test.MAIN OUTCOME MEASURES: Height of T wave and Migrations of ST section and changes of heart rate of ECG of rats before and after medication.RESULTS: Data of totally 30 rats was entered the final analysis. ①Height of T wave: The height was higher after medication than that before medication in three groups (P ＜ 0.01), but that in astragalus group was obviously lower than that in lanceolata group [(1.63±3.81), (2.18±2.93) mm,P ＜ 0.01]. ② Heart rate: The rate was lower after medication than that of before medication in three groups (P ＜ 0.01), and that in astragalus group was obviously lower than that in lanceolata group [(212.21 ±5.01),(221.18±5.66) time/minute, P ＜ 0.01]. ③ Height of ST section: There were not significantly different in three groups (P ＞ 0.05), and the difference was not obvious before and after medication (P ＞ 0.05).CONCLUSION: ① Both astragalus and lanceolata can protect experimental myocardial ischemia induced by pituitrin. ② Effect of lanceolata on reduction of T-wave height is stronger than that of astragalus, but the effect of lanceolata on reduction of heart rate is weaker than that of astragalus.
