[Dynamics of morphological changes in the spinal cord following exposure to non-ionizing microwave radiation].

The structure of different portions (cervical, thoracic, lumbar, sacral and coccygeal) of the spinal cord were studied in the experiments on 50 animals with the use of the Nissl, Zimmermann, Cajal and other methods on days 1, 10, 20 and 30 after exposure to non-ionizing microwave radiation (NMI). Single exposure to NMI (wave length 12.6 cm, intensity 400-500 mW/cm2) for one hour (cats) or four hours (dogs) produces a severe distress of glial neurones and cells, which is marked by the appearance of dystrophic processes along the entire spinal cord. The disease progresses, leading to abnormalities of motor and other physiological functions of the body.

[Ultracytochemical changes in the brain and liver in exposure to low-intensity nonionizing microwave radiation].

The morphological (including electron microscopy, histochemistry, morphometry) and biochemical methods were used in experiments on 478 white rats to determine the content of glycogen, tigroid substance, RNA, DNA and activity of the enzymes (SDH, MDH, LDH, G-6-PDH, phosphorylase) in intact animals after and during exposure to nonionizing microwave radiation (NMR), 30 and 60 days after the rehabilitation period, as well as after physiological exposures (hypoxia and NMR of higher intensity). It was disclosed that repeated exposure to little doses of NMR alters the structural and functional bases of the mechanisms that regulate cell metabolism, produces conformational changes in the chemical substances and thus exerts a damaging action on the delicate cell structures; redistributes the action on the pathways of energy formation at the expense of compensatory protein synthesis and the increase enzymatic systems; increases the resistance to hypoxia and action of NMR of higher intensities.
