[Effect of antenatal hypoxia on homocarnosine levels in the brain and blood of rats of various ages].

Content of homocarnosine was studied in brain and blood of 14, 30 and 70 days old rats, mothers of which were subjected to hypoxia, corresponding to the height 9,000 m within 1 hr, during 2 week pregnancy. In 14 days old animals content of homocarnosine was increased by 43% in brain and 2-fold in blood, in 30 days old animals it was decreased by 13% in brain and increased 5-fold in blood after the antenatal hypoxia as compared with controls. Content of homocarnosine was similar to control values in brain and blood of 70 days old rats with antenatal hypoxia.
