[Morphological changes in the vestibular analyzer in the dynamics of an experimental disorder of the cerebral circulation].

The alterations of microcirculatory structures and of neurons as a result of chronic cerebrovascular disturbances induced by ligation of the left common carotid artery were studied on 56 noninbred white male rats. The objects of investigation were central links of vestibular analyser such as anterior vestibular nucleus, posterior ventro-lateral part of hypothalamus, sensomotor brain cortex. It was established that one-sided ligation of common carotid artery resulted in alterations in vessels of microcirculatory bed, in neurons' bodies, in synapses.

[The pathomorphological changes in the epiphysis in chronic alcoholism].

Routine, histochemical and morphometric methods were used in examination of epiphyses in 45 autopsy cases of persons that suffered of alcoholism. Characteristic morphofunctional features of the epiphysis were found in those suffering from alcoholism with a stable and hard drinking character, alcohol epilepsy showing involvement of the epiphysis in the complex pathogenesis of the disease.

[Endocrine function of the epiphysis in disorders of cerebral circulation (morphological study)].

In a quantitative morphological study of the epiphyses from 56 patients whose death was related to various types of cerebral circulation disorders the authors have specified the characteristics of the endocrine function of this organ in each of the pathological types studied, with the status of the merocrine and "emergency" holocrine secretion of the epiphysis being assessed separately. The authors consider the possible significance of the identified epiphysis dysfunction in the development and course of cerebrovascular diseases and outline possible types of involvement of the epiphysis in their pathogenesis.
