Comparison of the effects of vasopressin and norepinephrine on organ perfusion during septic shock in streptozotocin-induced diabetic rats
Purpose ::: The purpose of this study was to compare the effects of norepinephrine (NE) and vasopressin on systemic hemodynamics, renal and mesenteric artery blood flow, inflammatory response and inducible nitric oxide synthase (iNOS) activity during endotoxin shock in streptozotocin-induced diabetic rats.
Abstract Preeclampsia is a multisystem disorder unique to human pregnancy, characterized by abnormal placentation. Although its causes remain unclear, it is known that the expression of several transporters is altered. Transient receptor potential vanilloid 1 (TRPV-1) is a nonselective cation channel, present in human placenta. Here, we evaluated the expression of TRPV-1 in preeclamptic placentas. We observed a deregulation in TRPV-1 expression in these placentas which may explain the impaired Ca 2+ homeostasis found in preeclampsia.
