alternation (SA) in a-maze which Ss were permitted to freely explore for 8-min sessions. …

Tolerance development to d-amphetamine induced motor motor activity was studied under
various experimental conditions. Following seven daily habituation sessions, female, albino …

Butorphanol (0.025, 0.05, 0.1, 0.2, 0.4, and 0.8 mg/kg of body weight, and placebo) was given
sc to 8 healthy unmedicated dogs to determine its efficacy for visceral analgesia, using a …

This study was designed to determine the effective analgesic dose of butorphanol administered
intravenously to obtund visceral nociception, as well as to determine duration of this …

α-Methyltyrosine (α-MT) has been proposed to cause central nervous depression by blocking
synthesis of brain catecholamines. However, interpretation of these reports is complicated …

This study was conducted to determine whether blood pressures and pulse rate could be
determined accurately by indirect measurements from the front and hind legs of 15- to 40-kg …

A modified flinch-jump procedure was used to detect changes in sensitivity to electric
