老年高血压病患者血清血管紧张素转换酶活性观察

Observation of the Activity of Serum Angiotensin Converting Enzyme in the Aged Hypertensive Patients

应用分光光度法测定１５例并内皮损伤、２８例无内皮损伤老年高血压病患者血清血管紧张素转换酶（ＳＡＣＥ）水平，并以１３１例正常人作对照。结果内皮损伤组、内皮无损伤组的ＳＡＣＥ各为１３７±３８．５ｕ、２９４±５７．８ｕ；分别低于和高于正常对照组（２４４±８２．５ｕ）。说明老年高血压病患者的ＳＡＣＥ活性随着并发血管内皮细胞损伤的有无而表现下降或升高。

The levels of serum aginotensin converting enzyme(SACE)were measured with spectophotometry in 43 cases of the aged hypertensive patients There were 15 cases of patients with and 28 cases of patients without complicating endothelial cells(EC)injured and 131 cases of normal persons as controls The results showed that the levels of SACE with and without EC injured were 137±38 5u and 294±57 8u respectively The former were lower and the latter higher than normal contrels (244±82 5u)It demonstrated that the activity of SACE in the aged hypertensive patients decreased or increased depended on the patients with or without EC injured
