Abstract
The experiments show that hypoxia training leads to an increase of the immunoreactivity to corticotropin and beta-endorphin and to an increase of the content of these neuropeptides. In this case, the ratio of the area of the immunoreactive material to the corticotropin/beta-endorphin, and the coefficient of their content in the PVN did not change significantly compared with the control. Thus, the selected hypoxia mode leads to adaptation, which is reflected in the balanced activity of stress-realizing and stress-limiting systems of rats' hypothalamus.
Keywords:
