Acute impairment of contractile responses by 17beta-estradiol is cAMP and protein kinase G dependent in vascular smooth muscle cells of the porcine coronary arteries.

abstract：BACKGROUND AND PURPOSE:Emesis is a multi-system reflex, which is usually investigated using in vivo models. The aim of the study is to compare the response induced by emetic compounds across species and investigate whether dogs, ferrets and rats are all similarly predictive of humans.
