[Postnatal development of the cerebellar Purkinje cell shape in guinea pig ontogenesis].

In sagittal cerebellum sections, morphometrical study of cerebellum of mature-born animals - guinea pigs - was performed using Nissl's procedure. A change of shape and volume of Purkinje cells and their nuclei in the course of the guinea pig postnatal ontogenesis was studied. It has been shown that both the growth process itself and the rate of formation of the definite form of Purkinje cells and of their nuclei in the course of ontogenesis proceeds non-uniformly.

Effect of epithalon on age-specific changes in the retina in rats with hereditary pigmentary dystrophy.

The effect of peptide bioregulator Epithalon on the course of hereditary pigmentary retinal degeneration was studied in Campbell rats. Administration of epithalon starting from birth protected morphological structure, increased its bioelectrical activity, and improved its function.
