Action of hypophyseal growth and thyrotrophic hormones in thyroidectomized rats.
It has been shown (Selye, 195 lb) that in unilaterally nephrectomized rats drinking 1 per cent. NaCi, electrophoretically homogeneous preparations of growth hormone (STH) caused nephrosclerosis, polyuria, myocarditis, and hypertension. This syndrome very closely resembles that produced by desoxycorticosterone acetate (DCA). However, one striking difference between the effects of STH and DCA is ...
متن کاملSynthesis of Sulfomucopolysaccharides in Thyroidectomized Rats
The thyroid glands of rats were made non-functional by a single dose of iodine-131 on the 1st day after birth or by surgical removal on the 28th day. The incorporation of sulfate-sulfur into the sulfomucopolysaccharides of skeletons and pelts was found to be significantly depressed by thyroidectomy. Daily supplements of 5 or 10 gamma of L-thyroxine, started on the 28th day, increased the uptake...
متن کاملUltracentrifugation of hypophyseal growth hormone.
Sedimentation velocity was measured in a Spinco ultracentrifuge’ operating at 165,000 X g. The hormone solutions (0.5 per cent) were prepared with borate buffer of pH 9.7 or saline at pH 9.1. Table I presents a typical run in a borate buffer; the sedimentation velocity constant was calculated by the procedure described by Svedberg and Pedersen (3). It may be noted that the individual values of ...

متن کاملThe Hypophyseal Growth Hormone, Nature and Actions
many formulae and figures. Its many chapter subheadings give the book its rather terse, outline form. A discussion of methods of isolation, characterization, and determination of purity is followed by successive chapters dealing with reaction rates as a function of substrate concentration, inhibitor action, temperature, and pH. Thermodynamic concepts are well developed in chapters on energetics...
