中药茶对高盐饮食大鼠的降压作用

目的本实验自拟中药茶方，通过测量大鼠血压、心率，观察该中药茶对高盐饮食大鼠的降压作用。方法设空白对照组（蒸馏水＋灌蒸馏水）、模型组（高盐饮食＋灌蒸馏水）和中药茶组（高盐饮食＋灌中药茶），每日一次按时灌胃，持续6周。结果与空白对照组比较．模型组大鼠血压较高（P〈0.05）；中药茶组与模型组比较明显降低（P〈0.05）；中药茶组与空白对照组比较，差异无统计学意义（P〉0．05）。试验期间各组间实验动物的体重和心率变化差异均无统计学意义（P〉0.05）。结论该中药茶对高盐饮食大鼠有一定的降压作用。

Objective To investigate the antihypertensive effect of Chinese materia medica tea on rats with high salt intake according to the blood pressure and heart rate. Methods The blank control group （ distilled water ＋ distilled water ） , the model group （ high salt intake ＋ distilled water ） and Chinese materia medica tea group （ high salt intake ＋ Chinese materia medica tea ） were set up. The experimental material was given to rats by gavage every day on time for six weeks. Results In comparison with the blank control group, the blood pressure of the model group was higher. However, blood pressure was decreased significantly in Chinese materia medica tea group compared with the model group. The difference between the blank control group and Chinese materia medica tea group wasn＇t significant. The changes of body weight and heart rate among all test groups weren＇t significant too. Conclusion Our Chinese materia medica tea has antihypertensive effect to rats with high salt intake.
