Abstract

Effects of carbacyclin, a synthetic analogue of prostacyclin on Na, K-ATPase, Ca, Mg- and Ca-ATPase activity of plasmatic membrane (PM) and sarcoplasmic reticulum (SR) of the heart normotensive (WKY) and stroke-prone spontaneously hypertensive (SHR-SP) rats were examined. In SR carbacyclin was found to increase Ca, Mg- and Ca-ATPase activity in SHR-SP and decrease the activity of this enzymes in WKY. Carbacyclin caused identical effect on ATPase activity in PM in WKY and SHR-SP, but the greatest effects were in WKY.

摘要

研究了前列环素的合成类似物卡巴前列素对正常血压(WKY)大鼠和易中风自发性高血压(SHR-SP)大鼠心脏质膜(PM)和肌浆网(SR)的钠钾ATP酶、钙镁ATP酶和钙ATP酶活性的影响。在SR中,发现卡巴前列素可增加SHR-SP中的钙镁ATP酶和钙ATP酶活性,并降低WKY中这些酶的活性。卡巴前列素对WKY和SHR-SP的PM中的ATP酶活性产生相同的影响,但对WKY的影响最大。
