Deuteron field-cycling relaxation spectroscopy and translational water diffusion in protein hydration shells.

The deuterated hydration shells of bovine serum (BSA) albumin, and purple membrane sheets have been studied by the aid of deuteron field-cycling relaxation spectroscopy. The deuteron Larmor frequency range was 10(3) to 10(8) Hz. The temperature and the water content has been varied.

[Mnemic disturbances following experimental alcohol-tranquilizer application (author's transl)].

Mnemic disturbances occurred in 8 of 14 subjects during a pharmcopsychological investigation of possible interactions between alcohol and dipotassium chlorazepate (Tranxilium). The blood alcohol concentrations were between 0.87% and 1.

Pharmacopsychological investigations concerning the combined effects of dipotassium clorazepate and ethanol.

The effect of a single dosage of 20 mg dipotassium clorazepate (DPC) on reaction times, with and without administration of ethanol (1 g/kg body weight), was studied in 14 male subjects. When administered in the evening, the sort-term effect of DPC consisted of slightly increased optic reaction times and decreased endurance and concentration. With simultaneous administration of ethanol, all types of performance studied were significantly impaired; impairment was more pronounced than with the ethanol tests.
