Enzyme histochemical studies on rat amygdala in fetal alcohol syndrome.
Histochemical studies were made of the activity of oxidative and hydrolytic enzymes in rat amygdala in FAS (Foetal Alcohol Syndrome). Ethanol in a dose of 9 g/kg/day was administered to rats during pregnancy and lactation in 6% aqueous solution as the only available liquid. The control rats received an equivalent diet in which ethanol was substituted by an equicaloric amount of sucrose. The offsprings were examined at the end of the 6th postnatal week. The activity of the lysosome and membrane enzymes, as well of some enzymes participating in the neurotransmission, was changed. A different decrease of the activity of oxidoreductases of Krebs cycle, glycolysis and pentose cycle was observed. The changes in the enzyme activity in the amygdala in FAS suggest alterations in the metabolism of the nervous tissue, rather than structural damages of cell organelles.
