Previous in vivo microdialysis studies have shown increased spontaneous release of 5-HT in the hippocampus of adult behaving rats exposed to prenatal protein malnutrition. Furthermore, behavioral studies have shown that adolescent rats (PD30) that have been prenatally protein malnourished demonstrate an increased sensitivity to the benzodiazepine chlordiazepoxide (CDP). Given this altered sensi...

Rats were trained to discriminate between saline and either 0.3, 1.0, 3.0 or 6.0 mg/kg of diazepam in a two-choice, discrete-trial avoidance procedure. Diazepam, chlordiazepoxide, flurazepam and pentobarbital occasioned dose-related increases in diazepam-appropriate responding in all four training dose groups. Increasing the training dose of diazepam from 0.3 to 1.0 mg/kg resulted in approximat...

Skin potential levels and EEG changes were recorded in eight psychiatric patients during three nights of sleep. In a balanced design each patient took amylobarbitone sodium 200 mg, chlordiazepoxide 30 mg and placebo in turn. Skin potential did not distinguish between wakefulness and sleep as measured by the EEG nor did it clearly identify individual sleep stages. However, significant difference...

We examined the effect on some clinical chemical assays of adding chlordiazepoxide or its two metabolites, the lactam and the N-desmethylchlordiazepoxide, to serum or urine. We also examined the effect on urinary steroid values of administering the drug for as long as 20 days. The drug, in 10-fold the expected concentrations in blood, or its metabohites, in 200-fold the expected Concentration i...

The extent to which a non-sedative dose of chlordiazepoxide (CDP) is able to modify the behavioral responses toward a predator odor was assessed in juvenile rats. Play behavior was suppressed and defensive behaviors were enhanced in the presence of a collar previously worn by a cat, when tested 24 h later in the same context as that where the exposure occurred, and when tested in a context diff...
