[Early ultrastructural reactions in various parts of the visual analyzer in guinea pigs after thermogenic microwave irradiation].

[Article in Russian]


A single total radiation of guinea pigs by means of microwaves of thermogenic intensity (energy density stream 60 mVt/sm2) and exposition for 10 min produces ultrastructural reactions in various parts of the visual analyser, differing in their manifestation degree. The most essential alterative changes have been revealed in the retina, appearing in 6 h after radiation, as degeneration of the membrane disks of the photoreceptors and as enhancement of phagocytic activity of pigmentocytes, and immediately after the radiation--as destructive disturbances of mitochondria in radial glyocytes and as reaction of the synaptic apparatus. In the cerebral visual centers a higher reactivity of neurons of the external geniculate bodies than in the visual cortex is noted, but ultrastructural disturbances of the hematoencephalic barrier and synapses of the visual cortex are more manifested. Early ultrastructural changes in the optic nerve are least manifested.
