The paraventricular hypothalamic nucleus (PVN) is a complex structure with both neuroendocrine and autonomic functions including cardiovascular control. The PVN contains angiotensin II (AngII) immunoreactive cells, fibers, as well as AT1 and AT2 receptors of AngII. We microinjected AngII into the PVN of normotensive anesthetized rats and simultaneously(More)
The hypothalamic paraventricular nucleus (PVN) controls cardiovascular regulation through vasopressin and sympathetic system. The PVN contains angiotensin II (AngII) and AngII receptors. We have already shown that microinjection of AngII into PVN produced a pressor response concomitant with an increase in firing rate of some PVN neurons. This study was(More)
The hypothalamic paraventricular nucleus (PVN) plays essential roles in neuroendocrine and autonomic functions, including cardiovascular regulation. It was shown that microinjection of angiotensin II (AngII) into the PVN produced a pressor response. In this study, we explored the probable mechanisms of this pressor response. AngII was microinjected into the(More)
BACKGROUND Iron dextran is in common use to maintain iron stores. However, it is potentially toxic and may lead to iron deposition (ID) and impair functions of organs. Iron overload can regulate the expression of inducible nitric oxide synthase (iNOS) in some cells that has an important role in tissue destruction. S-methylisothiourea hemisulfate (SMT) is a(More)
OBJECTIVES Bradykinin is a part of the kinin-kallikrein system which is involved in ischemia-reperfusion injury via B1 and B2 receptors. Noscapine is a non-competitive antagonist of bradykinin receptors. Noscapine has been reported to to be able to protect some organs against ischemia-reperfusion injury but its effect on renal ischemia-reperfusion injury(More)
