[Effect of sodium on the content and distribution of nicotinic acid in animal organs].

Tests conducted on rats kept for 2 months on a food ration deficient of sodium demonstrated a reduced concentration of nicotinic acid in the liver, kidneys, heart, lungs, brain and the muscles. In these conditions of the experiment intraperitoneal administration of 14C-nicotinic acid resulted in a greater incorporation of the tag in the organs of test animals as compared with controls. A particularly clearcut increase of such incorporation occurs with a 12-hour exposure.
