Abstract

The changes of activities of myosin light chain kinase(MLCK)and Ca2+/CaM-PP in different arterial vessels from hypertensive and normotensive rats were studied.The results were as follows.The MLCK activity of different arteries of spontanous hypertensive rats(SHR)was different with the order of aorta(A)＞＞caudal artery (CA)＞＞mesenteric artery (MA),while in WKY rats the order of activity among different arteries is A＜＜CA and MA and MA Ca2+/CaM-PP is obviously higher than in SHR.In renal hpertensive ras the activities of Ca2+/CaM-PP in different arteries are no quite different from those of the Wistar rats.The above results suggest that higher activities of MLCK or/and lower activity might be related to vasocontraction and hypertension.
