Abstract
In order to verify the assumption that changes in the content of osmiophilic bodies (OB) in pinealocytes in rats are a morphological marker not only of shifts in secretory activity and cal-cification of the pineal gland responding to round-the-clock lighting, but also reflect violations of pineal biorhythm, by methods of light and transmission electron microscopy, microrentgenospec-tral analysis in an experiment on rats, exposed to 48- hour exposure to bright light, the numerical density of single and grouped OB, their chemical composition was estimated. It is concluded that the grouped OB with the material of disposed mitochondria and calcifications are a residual manifestation of desynchronosis. Their content increases at an earlier time after exposure than the total content of various types of OB.
