Oxidative Stress as a Mechanisms of Reduced Glucose Absorption under Conditions of Immobilization Stress

Bull Exp Biol Med. 2017 Dec;164(2):132-135. doi: 10.1007/s10517-017-3941-5. Epub 2017 Nov 27.

Abstract

Experimental studies demonstrated inhibition of glucose absorption in the jejunum in acute and chronic 1-h daily immobilization stress, with the maximum inhibition on day 7 of immobilization. These changes correlate with the development of oxidative stress in animals over the entire duration of the experiment, which manifested by an increase in the content of the primary and end LPO products and decrease of the total antioxidant activity of the blood. Correction of these shifts with the antioxidant drug inhibits accumulation of LPO products and increases antioxidant defense and glucose absorption rate. These data prove the important role of peroxidation in regulation of glucose absorption.

Keywords: antioxidants; glucose absorption; immobilization stress; oxidative stress.
