Further studies of the cerebral chemoreceptor buffers as influenced by vasoconstrictor and vasodilator drugs and veratrum viride.

Effects of lipopolysaccharide-induced septic shock on rat isolated kidney, possible role of nitric oxide and protein kinase C pathways

Objective(s): Pathophysiology of sepsis-associated renal failure (one of the most common cause of death in intensive care units) had not been fully determined. The effect of nitric oxide and protein kinase C (PKC) pathways in isolated kidney of Lipopolysaccharide-treated (LPS) rats were investigated in this study. Materials and Methods: Vascular responsiveness to phenylephrine and acetylcholine...

Comparative Study of the Effects of Tetraethyl-

Persistence of elevated blood pressure in toxemia of pregnancy following autonomic blockade with tetraethylammonium chloride (TEAC) has been reported previously by the authors ( 1 ). Subsequently many of the patients studied were treated with subcutaneous veratrum viride with consistent depressor effects. The apparent opposing actions of these two drugs in toxemia, together with a suggestion th...

Comparative Effects of Metformin and Glibenclamide on Aortic Reactivity to Vasodilator and Vasoconstrictor Agents in STZ-Induced Diabetic Rats

Background: Diabetes is an important risk factor for cardiovascular events. Endothelial dysfunction is the main reason cause of disability and death in diabetic patients and death. The present study investigates the effects of metformin and glibenclamide on vasoconstrictive and vasodilative responses in the diabetic rat aorta. Methods: Rats were divided into four experimental groups (con...
