Changes in the Tigroid Substance of Neurons under the Effect of Radio Waves

摘要

Exposure to single radiation of a high-intensity 3-cm-band SHF field (0.4-0.5 w/sq cm) for 1 hour results in injury beginning in the cerebral and spinal-cord nerve cells of cats, taking the form of volume and shape changes, changes in the position and tinctorial properties of the nucleus and nucleolus, and regrouping of the basophilic granularity of the chromatophil substance up to pulverization. These injuries are more pronounced in some functional groups of neurons than in others. The sensory neurons are more labile, those belonging in the vegetative nerve system are less resistant, and the motor somatic neurons are the most resistant. The degree of morphological change in neurons in the case of an entire organism being exposed to an SHF field can serve as a reliable indicator of the injurious effect of radio waves. In determining the functional condition of the neuron from the histologic point of view, it is obviously necessary to take into account the condition of the nucleolus, its tinctorial properties, and its position, as well as changes in the condition of the tigroid substance and nucleus.
