Mean plasma prolactin levels obtained from male rats following anesthesia with ketamine, decapitation or via indwelling venous catheters were not significantly different although a larger variance was found in the samples obtained via catheters. Ketamine, at anesthetic doses, did not affect the increases in prolactin produced by reserpine or α-methylparatyrosine. Ketamine, at various doses, did not potentiate the effect of subthreshold doses of 5-hydroxytryptophan on prolactin secretion. Thus, ketamine would appear to be a suitable anesthetic for use in studies of prolactin secretion in male rats. Further studies in female rats are required. Supported in part by grant nos.
