[Microcirculatory bed of the rat ovary in health and under laser irradiation]. / Mikrotsirkuliatornoe ruslo iaichnika krys v norme i pri lazernom obluchenii.

Ovarian microcirculatory bed was studied using the method of scanning electron microscopy in albino rats during the helium-neon laser irradiation (632.7 nm wave length 0.76) 1 and 60 minutes long. Laser irradiation causes significant reorganization in the intraovarian vascular bed: capillaries become tortuous, relative section area, occupied by microvessels, grows significantly. Irradiation, elongated up to 60 min leads to stable increase of capillary diameter and appearance of pulsions along the capillary course.

[Functional morphology of capillary bed of the uterus after administration of synestrol]. / Funktsional'naia morfologiia kapilliarnogo rusla matki posle vvedeniia sinestrola.

The capillary vessels of rats uterus were examined. The animals who received 0.2% solution were examined 1, 3, 5, 10, 20, 30, 60 days after the last injection. As a marker for capillary vessels the histochemical method for finding the Mg++ adenosine triphosphatase was used. The studies have found prominent qualitative and quantitative changes (activity of enzyme, length and diameter of capillaries) not less than for two months after the last injection of the solution. Particularly prominent changes were found in endometrium between 10-20 days of the restorative period.

[The functional morphology of the uterine capillary bed after synestrol administration]. / Funktsional'naia morfologiia kapilliarnogo rusla matki posle vvedeniia sinestrola.

The capillary vessels of rats uterus was examined which were receiving for 7 days 0.2% solution of synoestrol i/m (2.0 mg per 1 kg of body weight). The animals were examined 1, 3, 5, 10, 20, 30, 60 days after the last injection of the solution. As the marker for the capillary vessels the histochemical method for finding the Mg2(+)-adenosintriphosphatase was used. The investigations have found prominent qualitative and quantitative changes (activity of enzyme, length and diameter of capillaries) not less than for two months after the last injection of the solution. Particularly prominent changes were found in endometrium between 10-20 days of the restorative period.

[Chemical nature of lachrymal products in the dolphin Tursiops truncatus]. / Izuchenie khimicheskoi prirody glaznykh vydeleniu del'fina Tursiops truncatus

Studies have been made on carbohydrate-protein complex (the ratio of carbohydrate to protein is equal to 1 : 2) in lachrymal products of the dolphin. It was shown that protein component includes 14 amino acids, in which diamino monocarboxylic acids amount to 58%. The ratio of the latter to monoamino dicarboxylic acids is equal to 4.3. Therefore the proteins of lachrymal products are basic ones. This peculiarity of the proteins and the absence of cystein and tryptophan in them indicate that these proteins are represented by histon-like ones, which exhibit high capacity to complex formation. It was demonstrated histochemically, that carbohydrate component of lachrymal reproduct is represented by chondroitin-sulfate B. By thin layer chromatography, neutral monosaccharides (galactose and fucose) were detected, which presumably constitute terminal links of the prosthetic groups.
