本文报告我们采用金氏改良法,测定了15例60岁以上老年原发性高血压者及13例以性别、年龄匹配的正常血压者PNE、PE的资料。结果老年高血压组及正常血压对照组PNE分别为0.253±0.131对0.261±0.128ng/ml,PE分别为0.088±0.049对0.116±0.071ng/ml,两组间差别均无显著性。但高血压组中I～Ⅱ期者8例PNE均高于7例Ⅱ期者(P<0.05、0.001)。表明老年高血压与正常血压之间PNE、PE含量均无差异,而老年轻型高血压I～Ⅱ期者高于Ⅱ期。提示老年轻型高血压者,有交感神经活性增强。
This article reports that we used the King’s improved method to determine the data of 15 cases of PNH and PE in elderly patients over 60 years of age and 13 cases of gender, age-matched normotensive. Results The PNEs in elderly hypertensive group and normotensive group were 0.253 ± 0.131 vs 0.261 ± 0.128 ng / ml, PE were 0.088 ± 0.049 vs 0.116 ± 0.071 ng / ml, respectively. There was no significant difference between the two groups. However, the PNE in 8 patients with stage I-II in hypertension group were higher than those in 7 cases with stage II (P <0.05, 0.001). Show that there is no difference between PNE and PE between senile hypertension and normotensive, while those with senile mild hypertension are higher than those in nodal stage Ⅱ. Tip elderly hypertensive patients, sympathetic activity increased.
