[Absorption of glucose and glycine in the small intestine of pigs in the presence of sodium nitrate].

Daily perfusion of the pig small intestine with the sodium nitrate solution entailed a 2-3-fold drop in absorption of glucose and 1.5-2.0-fold drop in absorption of glycine. The sodium nitrate solution being substituted with saline, the absorption of both substances recovered by approximately 80%. The toxic effect of sodium nitrate seems to be due to both the local effect upon the small intestine mucosa and the general effect upon the organism.
