The enzymatic activities of alkaline phosphatase (AP) and acid phosphatase (AcP) in the small intestine of Japanese quail chicks hatched on the orbital station "MIR" after their return to the Earth at the age of 4-5 days (experimental group) were compared with those of the chicks of the same age hatched on the Earth (laboratory control). A short term in space including the last days of embryonic development and the first days after hatching led to a decrease in normal food intake and to a significant increase in the AP and AcP activities in the duodenal and jejunal enterocytes in the experimental animals (P 0.001). Results indicate an increasing in the activity of both enzymes observed on days 4-5 after hatching - when their decrease occurs naturally in normally nourished animals - due to the delayed functional development of the digestive tract in these animals
