On lipid droplets in renal interstitial cells

Summary By examining Epon-sections of the renal papilla, it is demonstrated that acute hydration in dehydrated rats induces a considerable increase in the number of lipid droplets in the renal interstitial cells. It is supposed that the increase in number of lipid droplets represents a state of limited release. The attention is drawn to the correlation between the increased number of lipid droplets and the state of diuresis. The possibility of a correlation between the effect of ADH and prostaglandin and the release of lipid droplets is mentioned.This work was supported by a grant from the Danish State Research Foundation. — The author wishes to acknowledge the support and inspiration given by E.
