[Morphofunctional characteristics of malignant thyroid gland tumors in children from various regions of the Ukraine, who have been victims of of the Chernobyl nuclear power plant accident].

Thyroid cancers in children from the affected areas of Ukraine were investigated by means of light (33 cases) and electron (20 cases) microscopy. Statistical data from 25 regions of Ukraine have been analyzed concerning thyroid cancer in patients aged up to 18 years for the period 1981-1990.

[Morphologo-histochemical characteristics of ischemic cerebral infarcts in the acute stage of the stroke in patients with atherosclerosis].

Morphological and histochemical investigations of the activity of succinate, malate, lactate, isocitrate, and glucoso-6-phosphate dehydrogenases, and NAD-diaphorase in the central, marginal, borderline and perifocal zones of ischemic brain infarctions were carried out. Deep changes in the activity of the enzymes listed, and peculiarities of this activity in various brain structures and tissues were revealed. A connection between the activity of the enzymes, the duration of the infarction, and the structural and biochemical peculiarities of the affected brain part is demonstrated.
