摘要

测量自发性高血压大鼠(SHR)的血压、心率和体力活动,并与Wistar Kyoto大鼠(WKY)的血压、心率和体力活动进行比较,观察这些参数随年龄的变化情况,并在这些变量中是否可以找到原发性高血压的标志。采用自动遥测系统测量这些变量。在SHR中,血压和体力活动随着年龄的增长而增加,但心率下降。在WKY中,血压和体力活动都没有明显变化,但心率随着年龄的增长而下降。SHR组24小时血压、心率和体力活动平均值明显高于WKY组。SHR和WKY的血压、心率和体力活动平均值在夜间均高于白天。SHR患者的昼夜MESOR和血压波幅同时升高。这些结果与血压升高幅度可能预测原发性高血压后续发展的概念相一致。

Comparison of blood pressure, heart rate and activity between normotensive and spontaneously-hypertensive rats.

Blood pressure, heart rate and physical activity in spontaneously hypertensive rats (SHR) were measured and compared with those of Wistar Kyoto rats (WKY) to see how these parameters vary with age and whether we can find a marker of essential hypertension among these variables. An automatic telemetric system was employed to measure these variables. In SHR, blood pressure and physical activity increased with age, but heart rate decreased. In WKY, neither blood pressure nor physical activity showed significant changes, but heart rate decreased with age. The 24h mean values of blood pressure, heart rate and physical activity were significantly higher in SHR than in WKY. The mean values of blood pressure, heart rate and physical activity were higher during nighttime than during daytime in both SHR and WKY. Circadian MESOR and amplitude of blood pressure increased simultaneously in SHR. These results are compatible with the concept that an increased amplitude of blood pressure may predict subsequent development of essential hypertension.
