Differential sensitivity to ethanol,pentobarbital, and barbital in spontaneously hypertensive and normotensive Wistar-Kyoto rats

Ethanol, pentobarbital, and barbital sleep times and blood levels on awakening were determined in female spontaneously hypertensive (SH) and normotensive Wistar-Kyoto (WK) rats. Ethanol-induced sleep times were significantly longer for SH than for WK and blood ethanol concentrations on awakening were significantly lower in SH than in WK rats. By contrast, pentobarbital and barbital sleep times for SH rats were significantly less than for WK rats and barbiturate blood levels at awakening were significantly higher in SH than in WK rats. No differences were observed between SH and WK rats with respect to the disappearance of ethanol, pentobarbital, and barbital from blood and in the apparent volume of distribution of these drugs. These observations suggest differential CNS sensitivity of the SH and WK rats to ethanol and barbiturates and provide additional support for the notion that there exist differences in the modes of acute action of these drugs.

Feeding behavior in sheep as related to the hypnotic activities of barbiturates injected into the third ventricle

The central effect of barbiturates on feeding behavior was studied in sheep. Control or test solutions (0.5 ml) were injected at a rate of 0.19 ml/min into the third cerebral ventricle. Barbital, phenobarbital, amobarbital and pentobarbital elicited marked feeding (p<0.01) while secobarbital and thiamylal did not. The dose of barbital required to elicit maximum feeding was 240 μmoles/animal while for pentobarbital it was 30 μmoles. At these doses, barbital elicited a larger feeding response than pentobarbital (753±184 g vs. 394±178 g.. 2 hr postinjection, (p<0.01). No differences were observed between barbiturates that elicited feeding with respect to the latency of the response, within 2 min postinjection. Pentobarbital, but not barbital, increased intraperitoneal temperature (p<0.01), suggesting that pentobarbital had penetrated into brain structures involved in temperature regulation. The feeding responses observed may be related to the differences between barbiturates with respect to their lipid solubility and rate of penetration of biological membranes. Since barbiturates are neurodepressants, we suggest that they act by partially removing the influence of inhibitory neurons impinging on feeding centers of the lateral hypothalamus.     

GABAergic influences on barbital withdrawal induced convulsions

Animals which had been long-term treated with increasing concentrations of sodium barbital in the drinking water were killed 30 min or 72 hr after the last day of treatment, to determine striatal GABA levels and turnover rate. The effects of pentobarbital administration on GABA metabolism of rats withdrawn or not withdrawn from barbital were also studied. Barbital withdrawal induced a significant decrease in striatal GABA levels and also in the turnover rate after pentobarbital treatment. The latter effect was greater in rats killed 72 hr after drug removal. In control animals, pentobarbital treatment increased striatal GABA levels but did not affect the turnover rate. Barbital removal also made the rats less responsive to the effects of pentobarbital on striatal GABA levels. These results suggest the participation of a central GABAergic system in barbital withdrawal convulsions.

The effect of ofloxacin on pentobarbital-induced sleep in mice.

There have been several reports that insomnia occurs in some patients who receive ofloxacin. Since almost no experimental data on ofloxacin-induced insomnia were available, this study was conducted for the evaluation of ofloxacin effects on sleep parameters in mice. In Experiment 1, mice were pretreated with ofloxacin (20 or 40 mg/kg IP) or saline 15 minutes before sodium pentobarbital (35 mg/kg IP). Experiment 2 was carried out in two days. On the first day mice were treated twice, in the morning and in the evening, with ofloxacin (20 or 80 mg/kg IP) or saline. On the second morning, mice were pretreated with the same doses of ofloxacin or saline 15 minutes before sodium pentobarbital (35 mg/kg IP). Sleep latency and sleeping time were recorded in each experiment. Results showed that ofloxacin had no apparent effect on sleep latency, but caused a shortening in sleeping time. However, this effect was significant only in the 40 and 80 mg/kg ofloxacin-treated groups.
