Brain stem opioidergic and GABAergic neurons mediate the antinociceptive effect of nitrous oxide in Fischer rats.

abstract：BACKGROUND:The effects of triiodothyronine (T3) on systemic hemodynamics, myocardial contractility (preload recruitable stroke work slope; Mw), and left ventricular (LV) isovolumic relaxation (time constant; tau) were examined before and after the development of pacing-induced cardiomyopathy in conscious dogs.
