[Comparison of the diuretic and natriuretic effects of dopamine in control and diabetes insipidus dogs. Effect of propranolol].

The diuretic effect of dopamine is unchanged in the dog with diabetes insipidus but the natriuretic effect of dopamine is shorter. With the normal dog propanolol delays the dopamine-induced diuresis and natriuresis but the magnitude of this double effect is unchanged. In the dog with diabetes insipidus, propanolol suppresses the dopaminergic diuresis and reduces the natriuresis.

Bright light during nighttime: effects on the circadian regulation of alertness and performance.

The present studies evaluated to what extent duration (all-night or 4-hour exposures) and timing of nocturnal bright light (BL) (beginning or end of the night) modulate effects on vigilance. The results showed that all-night BL exposure is able to alleviate the nocturnal decrements in alertness and performance. However, under certain circumstances, this continuous BL exposure may induce adverse effects on mood and finally reveal to be counterproductive. Shorter BL exposure (4 h) during nighttime helps improve mood and performance, although the effects of short BL pulses were less efficacious than all-night BL exposure. The latter part of the night appears the best time for using the alerting effect of BL. The immediate alerting effect of BL seems to be mediated by a global activation of the central nervous system.
