Stimulatory effects of gamma-hydroxybutyric acid on growth hormone and prolactin release in humans.

A dose of 2.5 g of gamma-hydroxybutyric acid (GHB) was administered intravenously to 6 healthy male volunteers. A significant increase in plasma GH was observed at 30, 45, 60 and 90 min after injection. The plasma prolactin level increased significantly at 45 and 60 min after GHB injection. These responses were not found after the saline vehicle injection in the same subjects. It is conceivable that GHB could modify the release of serotonin from the nerve terminals and then stimulate the release of GH and prolactin.

Mechanism of suppressive effect of basic cupric acetate on rat liver carcinogenesis by ethionine.

The rate of ethylation of t-RNA in vivo by L-ethionine[ethyl-1-14C] markedly lowered in the liver of rats fed a diet containing copper than that of control. In corporation of the labeled compound into the t-RNA of liver by a single injection. of L-ethionine[ethyl-1-14C] was inhibited as much as 50% by the preceding concurrent administration of copper and ethionine added in the diet to rats. Direct interaction of copper ion with ethylation by ethione in the specific t-RNA of the rat liver was examined as an important biochemical explanation in molecular level for the inhibitory mechanism of copper on rat liver carcinogenesis by ethionine. Profiles of normal t-RNA on methylated albumin-kieselguhr column chromatography revealed three components for leucine, two of which were found at the tube number 40 to 50 and disappeared in the leucyl t-RNA treated with ethionine. The components for leucine that disappeared were normalized in the liver of rats by the concurrent administration of copper.
