[Predetermined phylo- and ontogenic characteristics of the distribution of lysosomal acid phosphatase in the digestive tract].
The pattern of the distribution of acid phosphatase activity in the alimentary tract was studied from the standpoint of phylo- and ontogenesis. Experiments made on beluga, crucian, frogs, grass snakes, pigeons, rats, 3-4-day-old cubs, 20- and 28-day-old rabbit embryos and 40-day-old rat embryos have shown that acid phosphatase displays its activity in all the parts of the alimentary tract. The lowest activity was recorded in the esophagus, rising progressively in the stomach and duodenum and reaching the maximal level in the distal part of the small intestine, and then dropping in the inferior parts of the intestine. It is assumed that such a mechanism of the distribution of lysosomal activity in the alimentary tract is formed at the early stages of the phylogenetic and ontogenetic development of the animals and is linked with the performance of the physiological functions.
