The effects of prolonged treatment of rats with zimelidine, 5, 12.5, and 25 ~tmol/kg PO twice daily for 2 weeks, on the accumulation of 14C-5-hydroxytryptamine (I#C-5-HT) and 3H-noradrenaline (3H-NA) in hypothalamic slices were studied. The concentrations of 5-HT and 5-hydroxyindoleacetic acid (5-HI

β¦ Synopsis
Seven-hour sleep EEG recordings were obtained from rats (N = 15) given a single acute dose, and rats (N = 15) given 14 daily doses of zimelidine, 20 mg/kg IP. REM latency, REM sleep, number of REM episodes, and total sleep time were significantly affected by zimelidine administration when compared to controls, as well as to each animal's baseline sleep parameters. Sleep latency and slow-wave sleep were not significantly affected by zimelidine. The results are discussed in terms of the implications of the use of zimelidine as a clinical treatment for depression, as well as the implications for the use of REM changes as a diagnostic indicator of the efficacy of treatment with zimelidine.

Sleep EEG (7 h) were obtained from 11 rats given 5, 10, and 20 mg/kg zimelidine, and a control dose of saline. Zimelidine significantly suppressed REM sleep, lengthened REM latency, and reduced total sleep time (TST) in a dosedependent manner. Sleep latency was not affected except at the highest dos
Cocaine in 6 mg/kg doses was administered orally and intraperitoneally to rats and sleep EEG's recorded. Cocaine significantly reduced total sleep time, slow-wave sleep, and sleep latency. Rapid eye movement sleep (REM) was significantly suppressed during the first half of the sleep recording. These
Rats were maintained on a regimen of restricted access to water. Desipramine (DMI) IP I h prior to the access period dose-dependently reduced water intake. Following completion of the dose-response determination for the effect of desipramine or water intake, rats were divided into three groups for r
