Effects of starvation on the parathyroid glands in golden hamsters of different ages, with special reference to the frequency of lipid droplets.
The frequency of lipid droplets in the parathyroid glands of young, adult and senile golden hamsters after starvation was investigated. In the parathyroid glands of the young and senile golden hamsters, the number of lipid droplets increased to reach a peak by 2 days, then decreased slowly by 5 days after starvation, and decreased rapidly after refeeding. In the glands of adult animals it increased to reach a peak by 5 days after starvation and decreased rapidly after refeeding. These findings suggest that in the fasting condition there is a relationship between the number of lipid droplets and aging.
