Pehidine interaction with clorgyline, pargyline, or 5-hydroxytryptophan: lack of enhanced pethidine lethality or hyperpyrexia in mice

Effects of tetrabenazine and phenylpiperidine analgesics during daily clorgyline treatment

Pigeons responded under a multiple fixed-ratio 30-response, fixed-interval 5-min schedule of food presentation. Daily administration of clorgyline (10 mg/kg, IM) tended to decrease rates of responding in both schedule components. Before daily clorgyline, tetrabenazine had no effect or decreased responding in the FI component at doses that markedly increased responding during chronic clorgyline. The clorgyline treatment resulted in a slight increase in sensitivity to the rate-decreasing effects of morphine, but no increased sensitivity to the rate-decreasing effects of meperidine, anileridine, alphaprodine, or fentanyl.

Changes in body temperature after administration of acetylcholine, histamine, morphine, prostaglandins and related agents

This survey, the second in a series, presents extensive tabulations of literature, primarily since 1965, on thermoregulatory effects of cholinergic agonists and antagonists, histamine and H1- and H2-receptor antagonists, narcotic analgesics and antagonists in both non-tolerant and tolerant subjects and of prostaglandins and related agents. The information listed includes the species used, route of administration and dose of drug, the environmental temperature at which the experiments were performed, the number of tests, the direction and magnitude of body temperature change and remarks on the presence of special conditions, such as age or lesions, or on the influence of other drugs, such as antagonists, on the response to the primary drug.
