[Effect of prenatal stress on the hypothalamo-hypophyseal-adrenal system activity and fat metabolism in the male water vole Arvicola terrestris].

The HPA axis function and the fat metabolism were studied in adult male water voles born to intact mothers and mothers deprived of food on the 15th and 18th days of their pregnancy. The HPA response to emotional stress was relatively low in experimental males in winter. The hormonal response to a 24-hrs food deprivation diminished in experimental group only in February. The blood level of free fatty acids was increased in experimental group as compared to the control one. The short maternal food deprivation modified adaptive abilities of their male progeny.
