摘要
目的 :研究高血压病 (EH)及并发脑梗死 (HCI)患者红细胞变形性 (RCD)及细胞膜 ATP酶活性的改变。方法 :采用粘度法、化学比色法测定了 2 0例正常人、 30例 EH及 30例 HCI患者的红细胞变形指数 (DI)、红细胞膜Na+ ,K+ - ATP酶和 Ca2 + - ATP酶的活性。结果 :(1) EH组与正常对照组相比 ,DI值显著升高 ,ATP酶活性降低 ,EH患者 DI与 ATP酶活性呈负相关 ,与 DBP呈正相关 ;(2 ) HCI组与 EH组相比 ,DI显著升高 ,ATP酶活性显著降低 ;HCI患者 DI与 ATP酶活性呈负相关。结论 :(1) EH患者 RCD降低 ,并与细胞膜 ATP酶活性降低及血压升高相关 ;(2 ) RCD降低可能与 EH患者脑梗死的发生有关。
Objective:To investigate the alteration of red cell deformability(RCD) and adenosine triphosphatase(ATPase) activity of cell membrane in essential hypertensive(EH) patients and essential hypertension patients complicated with cerebral infarction(HCI).Methods:Twenty healthy individuals,30 EH patients and 30 HCI patients were selected as subjects.The erythrocyte deformability indexes(DI)、Na +,K +\|ATPase and Ca 2+ ATPase activities were examined.Results:(1)EH patients had significantly higher DI,lower ATPase activity as compared to healthy individuals.There were significantly negative correlation between DI and ATPase activity,and a significantly positive correalation between DI and diastolic blood pressure in EH patients;(2)There was significantly higher DI,lower ATPase activity in HCI patients than those in EH patients.There was significantly negative correlation between DI and ATPase activity in HCI patients.Conclusion:(1)RCD decreases in EH patients,and RCD is correlated to the decreased ATPase of cell membrane and elevated blood pressure;(2)The decreased RCD level may be related to the occurrence of HCI.
