Cholesterol-3-3H,4-14C was injected intravenously in man and its transformation to cholestanol was studied. From the 3H:14C ratios in cholestanol isolated from blood, evidence for the participation of a ketonic intermediate in the conversion was obta

Mixtures of cholesterol-1,2-3H and sitosterol-4-14C have been incubated with suspensions of feces in order to compare the behavior of the phytosterol with transformations known to take place with cholesterol under these conditions. Within the limitat

That a necessary requirement for in vivo esterification of 3-hydroxy sterols is the equatorial conformation of the hydroxyl group has been substantiated by the administration of epicoprostanol-3β-3H (3-OH equatorial) to a man with a complete biliary

Seven patients were studied with 24Na to determine the relative disappearance time of the isotope from the postmastectomy lymphedematous arm as compared to the normal side. The results tend to confirm previously held convictions that the edema is usu
