Antidiabetic sulfonylureas: localization of binding sites in the brain and effects on the hyperpolarization induced by anoxia in hippocampal slices.

abstract：:Unanesthetized adult male rats with indwelling right atrial cannulae were used in the majority of experiments. Morphine (MOR, 3.0 mg/kg) caused a large but transient increase in both GH and PRL levels, which could be prevented with naloxone. Disruption of central noradrenergic function with diethyldithiocarbamate (400...
