reserpine/vomiting

Reserpine (0.5 mg/kg i.m.) produced emesis in pigeons with 60% of the animals responding. Metoclopramide HCl at 10, 20 and 40 mg/kg p.o. administered 30 min before or after reserpine injection was effective in blocking reserpine emesis. Metoclopramide was unable to antagonize reserpine-induced

1. Various antidepressant drugs and procedures have been studied against reserpine-induced emesis in pigeons.2. Electroconvulsions, pentylenetetrazol and a non-hydrazide monoamine oxidase inhibitor (pargyline) block reserpine emesis.3. It is suggested that reserpine-induced emesis in pigeons

The involvement of 5-hydroxytryptamine (5-HT) with cisplatin-induced emesis in the ferret was investigated using reserpine, para-chlorophenylalanine and fenfluramine. Pretreatment with reserpine (5 mg/kg, 24 hr), fenfluramine (5 mg/kg, 4 days) or para-chlorophenylalanine (100 or 400 mg/kg, 4 days)

In the present study, an attempt has been made to elucidate the role of alpha 2-adrenoceptors in reserpine-induced emesis in pigeons. Reserpine was found to induce dose-dependent emesis and a 500 micrograms kg-1 dose was found to be the 100% emetic dose. alpha 2-adrenoceptor agonists clonidine and

A 38-year-old man was admitted to Iwakuni National Hospital on July 6, 1978, with the complaints of difficulty seeing and walking. Two weeks before admission, he first experienced dizziness and it slowly progressed to uncontrollable tremor-like movements of the whole body. On admission, he was

The effect of injection of reserpine into the cerebral ventricles on the acetylcholine contents of the sino-atrial node, ileum and hypothalamus of the dog was studied in ten dogs. Another group of five dogs served as a control. The effect of intravenous administration of reserpine, in the same dose

Methyldopa potentiated hypnosis due to hexobarbitone in mice, as did reserpine, chlorpromazine and 5-hydroxytryptamine. Methyldopa antagonized the increase by reserpine of sleep due to hexobarbitone, but enhanced the potentiation by chlorpromazine and 5-hydroxytryptamine of hypnosis due to

1. Intravenously injected cisplatin at a dose of 4 mg kg(-1) induced early and delayed emesis in all pigeons without occurrence of lethality during a 72 h observation period. The early emetic response occurred with a latency of 81.3+/-8.0 min (n=15) and reached a peak at 2 - 3 h, and decreased

In unanesthetized cats the emetic action of dimethylphenylpiperazinium (DMPP) was investigated, after it was injected into the cerebral ventricles through chronically implanted cannulae. DMPP injected in 0.2-2.0 mg doses into the cerebral ventricle produced dose-dependent vomiting, which was

Intracerebroventricular injection of dopamine (0.5-4.0 mg) produced dose-dependent and short-lasting emesis (1-8 min) in cats, which was abolished after ablation of the area postrema. Relatively selective alpha 2-adrenoceptor antagonists (yohimbine and idazoxan) and a mixed alpha 1- and alpha
