[Stereology of the interstitial cells of the renal medulla in shock].

The authors carried out quantative stereologic studies on the electronograms of intersticial cells of the medulla of the kidney during shock. There was a considerable lowering of the number and volume of lipid granules in comparison with the control nontreated animals. The results were interpreted as a manifestation of the increased release of prostaglandins from the renomedullar intersticial cells as mediators of some local processes in the kidney, enduring shock.
