Abstract

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.

Main findings

In 50 animals examined 1, 10, 20, and 30 days after a single exposure to non-ionizing microwave radiation (12.6 cm wavelength; 400–500 mW/cm2), the authors report severe disturbance of glial neurons and cells with dystrophic processes throughout the spinal cord. The abstract states that the condition progresses and is associated with abnormalities of motor and other physiological functions.

Outcomes measured

Spinal cord morphology/structure (cervical, thoracic, lumbar, sacral, coccygeal)
Glial and neuronal cell changes (dystrophic processes)
Motor and other physiological function abnormalities

Limitations

No sham/control group described in the abstract
Species-specific exposure durations (cats vs dogs) without further detail
No quantitative outcome measures or statistical results reported in the abstract
Exposure metric reported as intensity (mW/cm2) without SAR or dosimetry details
