title: [The effect of a lyophilized extract of the mucosa of the proximal small intestine on kidney water- and salt-excretory functions in rats].
abstract: Experiments on Wistar rats injected intragastrically deionized water (1 % of the body weight) and intra-abdominally 0.1 mg/kg of the lyophilized water extract (LWE) from the thin intestine have shown that under these conditions diuresis and excretion of K+ with the urine increase and retention of Na+ excretion decreases. After intragastric injection of isotonic NaCl solution, the LWE has exerted only the K-excretion effect. An increase in the LWE doses from 1 to 10 mg/kg has weakened all these reactions. It has been found in experiments in vitro that the LWE has exerted an activatory dose-dependent effect on Na, K-ATPase from the kidney cortex cells.
