【摘要】 研究了肺心营养合剂（PX）对应激性高血压大鼠血流动力学的影响。结果PX灌胃28d后固定悬吊复制应激性高血压的大鼠（PH组）与生理盐水灌胃28d后固定悬吊复制应激性高血压的大鼠（NH组）比较，PH组的舒张压（DP）和平均动脉压（MAP）均明显低于NH组（P＜0．05），脉压（PP）则明显大于NH组（P＜0．05）。其收缩压（SP）较低，心输出量略高，但差异无显著性意义（分别为P＞0．1，P＞0．25）。PH组的SP略高于正常血压大鼠（NC组）（P＜0．05），而PP明显大于NC组（P＜0．01）。结果表明PX有抗高血压的作用，尤其是对舒张压的影响更为明显。更多还原

【Abstract】 The effect of a mixture of nutrients (PX) on hemodynamics in hypertensive rats was studied.High blood pressure was induced by fixing and hanging. The rats were divided into 4 groups: group hypertension (H), group hypertension pretreated with PX for 28d by gastrogavage (PH), group hypertension pretreated with normal saline for 28 d by gastrogavage (NH), and normal control group (NC). The resultsshowed that the diastolic blood pressure (DP) and mean arterial blood pressure (MAP) of group PH were significantly lower and the pulse pressure(PP) higher than those of group NH (P<0. 05). Although the systolic blood pressure seemed lower and the cardiac output higher in group PX than in group NH, there was nostatistical significance. The PP of group PH was also higher than group NC (P<0. 01 ). The results revealthat this mixture of nutrients has an inhibitory effect on high blood pressure especially on the diastolic bloodpressure.更多还原
