Differential chronotropic and inotropic effects of 2-nicotinamidoethyl nitrate (SG-75) in the dog isolated atrium.

abstract：:1. Stimulation of the mesolimbic dopamine system, by micro-injection of the substance P analogue [pGlu5,MePhe8,Sar9] substance P (DiMe-C7) into the ventral tegmental area induced a prolonged increase in blood pressure and circulating levels of vasopressin. 2. In the present study, this treatment produced a significant...
