BIOCHEMICAL STUDIES ON THE MALE HORMONE AS OBTAINED FROM URINE

摘要: The testicular hormone obtained from human male urine has been the subject of investigation by many workers, notably Funk, Harrow, and Lejwa (1, 2, 3), McCullagh, Hicken (4), Dodds, Greenwood, Gallimore (5, 6) Butenandt (7). With exception last mentioned author, extracts described these workers have rather crude compared to relatively high purity bull testis present authors. purpose this communication is a method for extraction purification comb-growth-stimulating substance found in compare chemical physiological properties with testis. acidified sulfuric acid within two hours after collection approximately 1 per cent volume. After filtering through cloth remove foreign particles, extracted benzene continuous extractor as shown Figure 1. When sufficient quantity has...
