[Level of microelements-metals in animal blood as an informative indicator of response to low-intensity short duration electromagnetic irradiation].

The comparison (juxtaposition) of the rats and the rabbits organism reactions on the electromagnetic irradiation (1.5 GHz, 300 microW/cm2, non-stop mode, 30 min) by the index of the physiological status indicators and of the blood microelements (ME)--metals concentration is presented. This physiological status indicators display that the mentioned irradiation is an underthreshold effect for central nerve system, which doesn't cause the essential changes on the organism level.

[The role of leukocytic infiltration in the development of neurogenic processes in the denervated rat cornea].

In early and late stages after different types of deafferentation of rat cornea extents of leukocyte infiltration and pathological changes are variable. Change of thickness of anterior epithelium and substantia propria, stratification of substantia propria fibres as well as epitheliocyte death and erosion occur only at late time intervals of deafferentation (after 1 d) when a large number of leukocytes appear in cornea. One day after the deafferentation performed following preliminary leukopoiesis suppression by irradiation, single leukocytes are encountered only in substantia propria of cornea while anterior epithelium thickness does not differ from that of intact animals, and the extent of pathological changes in substantia propria is reduced.

[The effect of electrostimulation of the hypothalamic mamillary nuclei on the vascular permeability of the skin in intact and capsaicin-pretreated rats].

Electrical stimulation of the hypothalamic mamillary nuclei increased the permeability of the skin blood vessels in rats. Pretreatment of the animals with capsaicin prevented the effect. The mamillary nuclei seem to take part in the central mechanisms of efferent function of the capsaicin-sensitive neurons.

[Primary heart neoplasms].

The work analyses the anatomomorphological characteristics of primary tumors of the heart in 106 patients; in 101 patients the tumor was benign (myxoma, neurinoma, rhabdomyoma) and in 5 malignant (angiosarcoma, liposarcoma). Surgical treatment was conducted in 99 patients; hospital lethality was 7.1%.

[Clinico-morphological basis of selection of the methods of treatment of echinococcosis of the abdominal organs and retro- peritoneal space].

The work is based on the analysis of surgical treatment of 2,985 patients with hydatid diseases of the organs of the abdominal cavity and retroperitoneal space. The character of the operative intervention is determined by the period of hydatid vital activity, its size, and the features of its localization within the organ. The authors identified the following periods of hydatid vital activity: living parasite, dead parasite; complicated echinococcosis.

[The microcirculatory disorders in deafferentation of the eye].

Microcirculatory disorders occurring in the eye of rats in the early period after deafferentation were studied. The blood flow in the iridic vessels became slower and permeability of the eye vessels was disturbed in the first hours and minutes after retrobulbar injection of the anesthetic trimecaine. Similar changes were encountered in division of the trigeminal nerve branches and in electrocoagulation of the sensory nucleus of the trigeminal nerve as well as in venous congestion induced by applying a ligature to the veins of the eyeball.

[Mechanism of the development of neuroparalytic keratitis].

There is a hypothesis that for appearance of the neuroparalytic keratitis a decisive role has cessation of discharge of trophic factors, demonstrating a polypeptide nature. from sensitive nervous endings. In order to check the hypothesis, deafferentation of the eye has been performed by means of electrocoagulation of the trigeminal sensitive nucleus in the medulla oblongata.

[Development of neuroparalytic keratitis after retrobulbar administration of trimecaine].

The blood flow in the iris vessels slowed down and the vessel permeability increased early after a retrobulbar injection of trimecaine, a local anesthetic, this resulting in the development of tissue edema. Two days later neuroparalytic keratitis developed. The authors suppose that early vascular disorders resultant from blocking of the sensitive nerves are among the causes responsible for later changes in the corneal trophics.

[Effect of deafferentation of the liver on hepatocytes located in various parts of the hepatic lobule].

Taking into account the data on functional heterogeneity of hepatocytes, situating in various parts of the hepatic lobule, influence of deafferentation of the cat liver on changes in the size of hepatocytes and their nuclei, as well as contents of glycogen and nucleic acids in their cytoplasm have been investigated. The greatest decrease of the glycogen contents and the greatest increase of the nucleic acids and the nuclei volume take place in hepatocytes, situating around the central vein.

[Role of smooth muscle cells in reparative processes in a vascular suture of the rat aorta performed using a microsurgical technic].

The abdominal aorta in 56 white rats has been sutured by means of a microsurgical technique in order to study changes that the smooth muscle cells (SMC) of the vascular wall undergo during the restorative process of its integrity and intima formation. The material for histological investigation is fixed in 10% formalin or in Karnoy fluid and embedded in paraffin. For the electron microscopic investigation the specimens of the aorta are treated in 2% and 5% glutaraldehyde solution and in 1% tetraoxic osmium solution and embedded in epon and araldit mixture.
