[Carbohydrates and enzymes of their conversion in rat brain tissues in adaptation to overcooling].
The content of glucose and glycogen in the brain as well as the enzymes of their conversion: phosphorylase, hexokinase, amylase were studied in single and repeated coolings of animals to the rectal temperature of the 19-20 degrees. Differences are established in the ways of conversion and utilization of glucose and different forms of glycogen in the brain tissue during cooling of the experimental animals and those adapted to cold. This results in appearance of a new type of carbohydrates metabolism in the brain tissue at formation of phosphorylated forms of glucose.
