Ouabain has recently been reported to be an endogenous mammalian substance released by the adrenal cortex and present in normal plasma. We have attempted to confirm and extend this observation. Using a ouabain radioimmunoassay developed in this laboratory, we fractionated by high-performance liquid chromatography (HPLC) normal human plasma from healthy volunteers to determine the presence of ou...

The present studies show that human platelets can incorporate uniformly labeled W-L-leucine into trichloracetic acid-precipitable material. This material is digested by Pronase but not by deoxyribonuclease or ribonuclease. Acid hydrolysis of the material liberates a compound with chromatographic properties identical with those of authentic r,-leucine. The incorporation of uniformly labeled 14C-...

ZONDEK [1934] reported the preparation of crude alcoholic eXtracts of horse testes which possessed a marked oestrogenic potency. Extracts obtained in this way were three hundred times as active oestrogenically as those prepared from a similar weight of mares' ovaries. The high oestrogenic potency of horse testes extracts has been confirmed by later workers. The present investigation was underta...
