[Clinico-functional status of the small intestine in patients with chronic opisthorchiasis]. / Kliniko-funktsional'noe sostoianie tonkoi kishki u bol'nykh khronicheskim opistorkhozom.

Examination of 110 patients with chronic opisthorchiasis lasting for over 5 years has revealed the syndrome of malabsorption by means of the d-xylose test, Kamer's method and radioindication. Dysbacteriosis, hypokinesia of the small intestine, reduction of the cholate-cholesterol ratio of the bile, structural alterations in the small intestine mucosa were found to be implicated in the genesis of malabsorption. The helminthologic recovery of the patients with protracted opisthorchiasis did not entail complete normalization of the function of the small intestine and thus required therapeutic correction.

[Morphological reactions of neural elements in the limbic region of the cerebral cortex to whole body roentgen irradiation]. / Morfologicheskie reaktsii nervnykh élementov limbicheskoi oblasti kory mozga na obshchee rentgenovskoe obluchenie.

After whole-body X-irradiation with a dose of 5 Gy, the content of limbic neocortex cells of altered neurocytes markedly increases: many of the disorders in their structure are reversible. In the inner cell complex the neurocytes with "dark type" changes are frequent and, in most cases, irreversible. Different types of gliocytes respond in a different manner to the effect of ionizing radiation.

[Characteristics of the cerebral cortex neuronal reaction to exposure to an alternating magnetic field during the administration of glutamic acid]. / Osobennosti reaktsii neironov kory golovnogo mozga na vozdeistvie peremennogo magnitnogo polia pri vvedenii glutaminovoi kisloty.

The irreversible changes accompanied by the impairment of the structure and architectonics of the neurons have been established to appear in the cerebrum parietal cortex of the white rats under the total fivefold 6,5 hr force of alternating magnetic field (20 mT, f = 50 hz). The preliminary hypodermic administration of sodium glutamate (1 mg/g mass of the body) to the animals decreases considerably the damage of the cerebral cortex neural elements.

[Sequence of pathomorphological reactions to the action of alternating magnetic fields]. / Posledovatel'nost' patomorfologicheskikh reaktsii na deistvie peremennykh magnitnykn polei.

The state of the parietal cortex neural elements in the white rat brains exposed to a total 5-fold effect lasting for 6.5 hours and to a single continuous 24-hour's effect of the magnetic field (strength 20, 40, 70 mT, frequency 50 Hz) have been studied light optically and electron microscopically. The most manifested pathomorphological changes are observed after the 5-fold effect lasting for 6.5 hours. The cortical vessel walls, filamentous astrocytes connected with them, as well as dendrites and spiculae are evidently the most injured formations and perhaps are the first to participate in the response reaction mechanism to the effect of the magnetic field. Hydropic changes appearing everywhere speak in favour of the water-electrolytic balance disturbance, evidently this phenomenon is specific for the magnetic field effects.

[Pathomorphological reactions of the cerebral cortex nerve elements during treatment with an alternating magnetic field]. / Patomorfologicheskie reaktsii nervnykh élementov kory bol'shogo mozga v usloviiakh primeneniia peremennogo magnitnogo polia.

The results of investigations of certain aspects of the effect of magnetic fields on the nervous tissue are presented. The time course of pathomorphological reactions of the nerve cells and neuropile of the parietal cerebral cortex of rats receiving a single 61/2-hour treatment with alternating magnetic field (induction 20 mT, frequency 50 Hz) was studied. Changes in the microcirculatory bed of the cortex were observed manifested mainly by hydropic disorders in the cellular and fibrous components of the vessel wall. The effect of magnetic fields may be probably characterized by various hydropic changes in the cells, glial elements, and dendritic apparatus realized through disorders in the water-salt balance in cells.
