Hypoxic pulmonary vasoconstriction (HPV) of rat pulmonary arteries in vitro occurs in four phases. Initial vasodilation (phase 1), is followed by transient contraction (phase 2), further vasodilation (phase 3) and finally a second sustained contraction (phase 4). We have investigated the role of
Cholinergic system is important for respiratory control from the first days of life. Disturbances in cholinergic pathway due to early life stress like hypoxic shock can adversely affect the ventilatory response. The present study evaluates neonatal hypoxic insult mediated cholinergic disturbances
Interest in the endothelium has been growing in recent decades and the traditional belief that it provides an inert interface between blood and the vessel wall is no longer the case. It is now clear that the endothelium produces a large number of substances that influence blood flow, and it is in
