Action potential duration (APD) lengthening is believed to underlie the cardiac arrhythmogenicity of ketanserin, a serotonin (5-HT)2A/2C receptor antagonist. We wished to determine (a) whether this activity involves blockade of 5-HT2A/2C receptors and (b) the precise mechanism of ketanserin-induced APD
The kappa opioid, U50,488, was examined alone and in combination with the 5HT2 antagonists, ketanserin, pirenperone and LY 53857. Squirrel monkeys responded under a shock titration procedure in which shock intensity increased every 15 s from 0.01 to 2.0 mA

Stimulus control was established in a group of nine rats using a dose of EGb 761 of 10 mg/kg, administered i.p., 15 min before training. A two-lever operant task using a fixed-ratio 10 schedule of sweetened milk reinforcement was used.

The experiments examined the effects of acute administration of three different serotonergic receptor antagonists (ketanserin, pirenperone and mianserin) on one-trial passive avoidance retention in mice. Administration of each antagonist 30 min before training produced a dose-dependent impairment in retention. In

The mouse defense test battery (MDTB) has been designed to investigate defensive reactions in Swiss-Webster mice to situations associated with a natural predator, the rat, such as flight, avoidance, defensive threat, defensive attack, and risk assessment activities. The present study
