The light/dark (L/D) rhythms of food and water intake, urine output and Na+, Cl- and K+ excretion were studied in male Wistar albino rats subjected either to constant light (LL) or darkness (DD). The LL regimen had a suppressive effect on the daily food and water intake, urine output and sodium excretion, combined with an elimination of L/D variations in all parameters studied. The DD regimen caused a decrease of the daily food and water intake, and sodium and chloride excretion. The L/D… CONTINUE READING
