Angiotensin II-induced calcium signaling in the afferent arteriole from rats with two-kidney, one-clip hypertension.
The aim of this study was to investigate ANG II-induced Ca2+ signaling in freshly isolated afferent arterioles (AA) from two-kidney, one-clip hypertensive (2K1C) rats, which have an elevated plasma and renal ANG II level, and different perfusion pressure and vascular tone in the clipped and nonclipped kidney. The Ca2+ responses in vessels from 2K1C and control rats were similar in all groups (P...
متن کاملCrocin prevents acute angiotensin II-induced hypertension in anesthetized rats
Objective: Angiotensin II (Ang II), the main product of renin-angiotensin system (RAS) has a well-known role in cardiovascular regulation. Over-production of Ang II is one of the important underlying mechanisms of hypertension. In this study, the effect of crocin on cardiovascular responses in rats with acute hypertension induced by Ang II was evaluated. Materials and methods: Rats were divided...
متن کاملIncreased angiotensin-converting enzyme activity of aorta in two-kidney, one-clip Goldblatt hypertension in rats.
There is increasing evidence that conversion of angiotensin I into angiotensin I1 can occur in the renal vasculature of humans [l l , and in the vascular beds of the hind limb of the dog 121. In previous experiments the specific angiotensionconverting enzyme in rat aorta [31 has been demonstrated. More recently, Mizuno et al. [41 have studied the subcellular localization of the enzyme activity ...
متن کاملBody fluid volume and angiotensin II in maintenance of one-kidney, one clip hypertension.
To investigate the possible role of body fluid volume or the renin-angiotensin system in the maintenance of high blood pressure in chronic one-kidney, one clip (1K1C) hypertension, we studied whether blood pressure remained high after removal of the clip while the body fluid volume was kept constant or when angiotensin II (Ang II) was infused in conscious 1K1C rats. Blood pressure fell 58 +/- 1...
متن کاملIncreased vascular formation of angiotensin II in one-kidney, one clip hypertension.
To assess the role of the vascular angiotensin II-generating system in one-kidney, one clip hypertension, we determined the angiotensin converting enzyme activity in plasma and vascular tissues and examined the pressor response to angiotensin II, angiotensin I, and tetradecapeptide renin substrate in isolated mesenteric arteries from one-kidney, one clip hypertensive rats 7 and 30 days after cl...
