Abstract

RECENT reports from these laboratories1,2 show that, during the winter months, normal male hamsters exposed to short daily periods of light [light:darkness (LD, in hours) = 1:23] or eyeless hamsters exposed to long periods of light (LD = 16:8) exhibit marked gonadal atrophy within 4 weeks. This effect is prevented if the animals are first pinealectomized. No significant effects are observed on weights of the adrenal gland. These studies were expanded to measure the responses of female hamsters to the two daily light cycles and to ascertain the relative influence of the pineal gland on these organs.
