EFFECTS OF PRE‐WEANING AND POST‐WEANING UNDERNUTRITION ON ACETYLCHOLINE LEVELS IN RAT BRAIN

Abstract— Studies were made of the effects of undernutrition during the neonatal period and also protein deficiency and undernutrition during the post‐weaning period on brain acetylcholine. Rats undernourished from birth to 4 weeks so as to result in a body wt deficit of 43 per cent had an associated deficit in brain wt of 14 per cent, but the concentration of acetylcholine in the brain was not affected. In the case of post‐weaning undernutrition, acetylcholine concn was found to be affected in protein deficiency as well as in severe calorie restriction.
