The study of the role of visual analyzers at physical loading is very important for deep understanding of mechanism of the change of carbohydrate exchange at stimulation of interoceptors. Taking into account the urgency of this problem, the purpose of the present paper is the study of interoceptive glycemic reactions of enucleated and epiphysectomated animals in postnatal ontogenesis.

The experiments have been carried out with 1,3 and 6-month animals. The change of cerebral cortex tonus has been made by enucleation method (V. S. Galkin, 1933) and epiphysectomation (a. S. Aulova, 1963) of visual analyzers.

After irradiation of rectum receptors under the pressure of 10-12 kPa during 1,5,10,15,30,45,60 min and taking the blood from the edge of the ear vein of animal, the amount of blood sugar has been determined by the Hagedorn-Yensen Method.

To determine a sugar exchange, the experiments have been repeated in 7,15,30 and 60 days after operation.

It has been found that the blood sugar amount in enucleated animals is lowered as compared to intact animals, while the epiphysectomated animals has a high percent of sugar in blood.

In all the age groups the blood sugar amount considerably increases under the effect of 5 min physical loading as compared to 30 min physical loading. After irritation of rectum receptors at 10-12 kPa the change of glycemic reaction level of 6-12 month animals is more prominent as compared to 1-3 month animls. After a physical loading the interoceptive glycemic reaction level of enucleated and epiphysectomated animals is lowered as compared to intact animals.

The obtained data indicate that the connection between interoceptive and extraceptive informations at physical loading and after operation plays an important role in reduction of lost functions of organism. These changes confirm an essential role of epiphysis in regulation of interoceptive glycemic reactions of enucleated and epiphysectomated animals.
