ХАРАКТЕР ЦИТОЛОГИЧЕСКИХ ИЗМЕНЕНИИ В КЛЕТКАХ СПЕРМАТОГЕННОГО ЕПИТЕЛИЯ И ЭЯКУЛЯТА В УСЛОВИЯХ ЭТАНОЛОВОЙ ИНТОКСИКАЦИИ Грицуляк Б.В., Грицуляк В.Б., Глодан О.Я., Долинко Н.П., Спасская А.М.
Гистологическим, елекронномикроскопичним и лабораторным методом исследовано влияние этанола на сперматогенез в условиях эксперимента. Установлено, что в отдаленные сроки исследования этанол вызывает гистоструктурные изменения в извитых семенных канальцах с достоверным уменьшением количества первичных и вторичных сперматоцитов и сперматид. В эякуляте достоверно снижается концентрация сперматозоидов, количество нормальных и живых сперматозоидов, сперматозоидов с прогрессивным движением. Параллельно увеличивается количество мертвых и патологических форм сперматозоидов. По данным электронной микроскопии в этих условиях нарушается ультраструктура элементов собственной оболочки извитых семенных канальцев, поддерживающих эпителиоцитов, их соединительного аппарата, головки и жгутика сперматозоидов.
Ключевые слова: клетки сперматогенного эпителия, этанол

THE CHARACTERISTICS OF CYTOLOGICAL CHANGES IN CELLS OF SPERMATOGENIC
EPITHELIUM AND EJACULATE UNDER CONDITIONS OF ETHANOL INTOXICATION Grytsuliak B.V., Grytsuliak V.B., Glodan O.J., Dolynko N.P., Spaska AM. The influence of ethanol on spermatogenesis in the experimental conditions was investigated by histological, electron microscopic and laboratory methods. It has revealed that in the long term of the experiment ethanol causes histostructural changes in the convoluted seminiferous tubules with a certain decrease in the number of primary and secondary spermatocytes and spermatides. In ejaculate, the concentration of sperm, the number of normal and live sperm, sperm with progressive movement is likely to decrease. In parallel, the number of dead and pathological forms of spermatozoa increased. According to the electron microscopy data under these conditions, the ultrastructure of the elements of the tunica propria of the convoluted seminiferous tubules, Sertoli cells, their junctions, heads and tails of the sperm were damaged.
Key words: spermatogenic epithelium cells, ethanol.

THE METHACRYLATE EFFECT
E-mail: [email protected]
The present study is devoted to the structural components changes in the rat tongue dorsum mucous membrane after the action of 1% methacrylic acid ether, manifesting itself in the epithelial plate's differentiation processes disorder in the form of hyperkeratosis. The plate's thickness is increasing during the observation period due to hyperhydration of the amorphous substance, which is accompanied by the height reduction of the connective tissue papillae. Changes in the hemomicrocirculatory bed's links are manifested by the resistance and capacity links narrowing on the 14th day of the experiment with a certain restoration of indices on the 30th day. During the observation, the expansion of the capillaries lumen by 20% was determined.
Keywords: mucous membrane, tongue dorsum, rat, 1% methacrylic acid ether.

the use of removable dentures is exposed to the influence of various negative factors [6]. Among the polymeric materials used by dental technicians and other specialists in the field of orthopedic prosthetics, the most adverse effects on human health are described under the influence of methylmethacrylate monomers and polymers [2].
The acrylic plastic over-denture, besides the traumatic, has a toxic and allergic effect on the denture-supporting area tissues in almost 40% of the patients using it [3]. Morphological study of oral mucosal changes in Wistar line rats under the effect of methyl methacrylate, a monomer of acrylic plastics, showed that with prolonged exposure to methyl methacrylate on the oral mucosa, at a concentration of 1% for 30 days, there were structural changes in all layers of the mucus that caused the development of toxic inflammatory process. Also, degenerative changes in epithelial cells are taking place, with signs of epithelium reparation, which is manifested by its hyperplasia, acanthosis, and focal hyperkeratosis [7]. In the works of many authors, changes in the action of methyl methacrylate on the gums status and the effects of the prosthesis on the teeth condition and the denture-supporting area were studied, but little attention was paid to the tongue status.
The morphometric method permits to objectify the results obtained in the organs' structural elements after the action of various endogenous and exogenous factors [1].
The purpose of the work was to determine the structural features of the mucous membrane of the tongue back dorsal surface in rats after the methacrylate administration.
Material and methods. The total of 25 white outbred male rats: control (5 animals) and experimental (20 animals) which oral cavity mucous membranes were treated with a 1% solution of methacrylic acid methyl ether had been involved in the study for 30 days [8].
After the euthanasia of animals on the 14th and 30th day, the fragments of the gum mucosa were sealed in epon-812 [4]. Semifine sections were stained with a polychrome stain. Morphometric study and microphotography were performed using Biorex-3 VM-500T microscope with digital DCM 900 photomicrographic attachment with adapted software for the given studies.
Quantitative assay of the morphometric study results and statistical processing of morphometric data were performed in accordance with generally accepted statistical methods using the Exel software[5]. The average thickness of the epithelial and proper mucous plates, the diameters of the arterioles, capillaries and venules lumen were determined. Management and manipulations with animals were carried out in accordance with the "Common Ethical Principles of Animal Experiments" adopted by the First National Congress on Bioethics (Kyiv, 2001), and also with the guidelines of the "European Convention for the Protection of Vertebrate Animals Used for Experimental and Other Scientific Purposes" [ 9].
Results of the study and their discussion. When performing morphometric studies on the tip of the tongue mucous membrane, it was found that the mean values of the epithelial plate's thickness were 73.82 ± 0.62 ^m, the thickness of the plate itself was 15.87 ± 0.43 ^m, and the height of the papillae's connective tissue was 37.56 ± 1, 39 ^m (table 1).

MORPHOMETRIC CHARACTERISTICS OF RAT SALIVARY GLANDS HEMOMICROVASCULATURE CAPACITY COMPONENT UNDER NORMAL CONDITIONS
AND IN ETHANOL CHRONIC INTOXICATION
E-mail: [email protected]
Data of the morphometric study on chronic ethanol intoxication are presented in the paper. It has been established that chronic ethanol intoxication affects the capacitive link of the hemomicrovasculature of the submandibular salivary glands. At the early stages of observation, venules dilation is determined, which is confirmed by a significant increase in the outer diameter and the lumen diameter with the vascular wall thickness reduction. From the twelfth day the tendency is observed towards the metric indices restoration. Normalization of the indices is not determined by the thirtieth day.
Keywords: chronic ethanol intoxication, rats, salivary glands, venules.

The problem of alcoholism is considered to be topical all over the world and ranks third after cardiovascular and oncological diseases by the mortality rate. According to the WHO statistics, there are about 140 million people in the world suffering from chronic alcoholism, but the fact should be assessed that more than half of them refuse to seek assistance of health professionals. In Ukraine, there is a high level of alcohol consumption by adolescents and student youth, which is directly a socio-demographic issue concerning the entire population. To fight against alcohol, medical and social diagnostic techniques are used in many countries to find the best solutions for treatment and recovery of alcohol dependent people [1].
Scientists are increasingly focusing on the study of salivary glands. The interest of researchers in studying the patterns of the salivary glands response to various stimuli has recently increased significantly, which is due to the diagnostic value of saliva as a highly informative object for the clinical assessment of the whole body's state. Large salivary glands undergo special changes in this case, being highly sensitive to the action of physiological, pathogenic factors [2].
In human and animal saliva, substances affecting hemomicrocirculatory hemostasis, blood clotting ability and fibrinolysis have been detected. Interaction of the hemostasis system with lipid peroxidation reactions and antioxidant system is well-known. It can also be traced at estimating the salivary glands functions [3].
The state of the hemomicrovasculature parts has significant impact on the organs functioning, particularly its capacity component, which provides a fully functional outflow of blood from tissues,
