Abstract

A histochemical investigation was made of aminopeptidase activities using L-leucine-beta-naphthylamide and D, L-alanine-beta-naphthylamine as respective substrates in the rat's sensomotor cortex neurons during the period of ethanol withdrawal after a prolonged alcohol intoxication. Alcohol intoxication of the rat continued for 8 months. Different dynamics of aminopeptidase activities was shown depending on the substrate used during ethanol withdrawal. The results are discussed from the point of view of the existence of multiple forms of aminopeptidase in the brain and of their involvement in protein metabolism in pathological states.
