title: [Age- and sex-related differences of neuroendocrine center reactions in the hypothalamus on preparation thymalin and alpha-tocopherol acetate].
abstract: In experiment the action of Thymalin, alpha-tocopherol and stress on the centers of hypothalamus related to the regulation of the gonadotropic function has been investigated and the age-specific features of such influence as well. The results of experiments indicate the presence of neuron's reaction of the rostra preoptical area and arcuate nucleus for experimental influences. As a stress exposure and alpha-tocopherol injection to the young animals a reduction of neuron's kernels of the arcuate nucleus was observed, a sexual distinction wasn't revealed in the process. The response age-specific feature for alpha-tocopherol injection of the nucleus neuron's rostra preoptical and arcuate area of the hypothalamus of white rats is a reduction in a degree of response. Thymalin reduces a threshold of sensitivity of the neuron's arcuate center to action of stress.
