Remodeling of Wall Mechanics and the Myogenic Mechanism of Rat Intramural Coronary Arterioles in Response to a Short-Term Daily Exercise Program: Role of Endothelial Factors.

abstract：:This study was designed to establish the in vitro pharmacological responses of rat middle cerebral arteries (MCA), and also their susceptibility to overnight cold storage at 4 degrees C. MCAs were harvested from rats and pharmacological responses were studied using a Mulvany myograph. Responses to prostaglandin F2 alp...
