COMPLEX HEAVY METAL SALTS EFFECT ON MORPHOLOGICAL FUNCTIONING CONDITION OF THE NUCLEI OF GANGLION NEURONS OF WHITE MALE RATS’ CEREBELLAR CORTEX

Abstract:

In order to analyze the dynamics of morphological and morphometric nuclear rearrangements of cortical cerebellar Purkinje cells under prolonged exposure (for 90 days) on the body of copper sulfate, zinc and iron experiment was conducted on 48 white adult male rats weighing 200-250g, aged 5 -8 months. We used an electron microscope method. It was found that the combined effect of copper sulfate, zinc and iron on the body has nuclear device ganglion neurons in the cerebellar cortex sufficiently expressive toxicity. The degree of morphological mutations in the nuclear unit is in direct proportion to the duration of the experiment. In the nuclei of ganglion neurons develop nonspecific changes of polymorphic nature, which is reversible in the early stages of experience and irreversible, mainly necrobiotic character (chromatolysis, pycnosis and reksis) in most of the neurons within a timeline.
