Introduction. One of the target organs of xenobiotics is the liver, wherein severe impairments of tissue structure developed under the influence of toxic substances, which manifest as dystrophy, bloodstream widening, and hepatocyte regeneration disorder. Liver as the biggest gland in the organism, receives double blood irrigation enriched with oxygen by its own hepatic artery and nutrient - rich from the portal vein being the first organ that receives metabolic substrates and nutrients from food. Therefore, the liver is constantly exposed to toxic substances that are absorbed, degrade, and conjugate.
Goal of research is to study the influence of tetraborate sodium on liver structure.
Methods. Chronic impact of sodium tetraborate on structure of a liver of white, not purebred rats - males was studied. Research was conducted on 30 puberal rats (10 intact, 10 control, 10 experimental). Sodium tetraborate was administered to the experimental animals within 2 months intraventricularly in a dose of 150mg/kg (1/30 LD50). After histologic diagnosis paraffin sections of a liver were stained with hematoxylin and eosine and according to Van Gieson.
Results. At chronic poisoning with sodium tetraborate the blood stasis - filling with blood of the central vein of a hepatic segment, expansion of sine capillaries, overfilling with blood of interlobular veins were observed. The degenerated cells (12,3±1,24%) were observed, generally round the central vein.They did not occur in intact and control animals. The number of two-nuclear cells was increased to 12,7±1,75% (in control 5,8±0,41, %). There was an increase in the polyploid cells, if in the control they made 2,2±0,12%, then in experiment their quantity reached 4,3±0,27%.
Conclusion. The toxic effect of borax induces degeneration of hepatocytes. The toxic substance effect produces an inflammatory process, accompanied by intensified exudation and formation of a large amount of tissue fluid, which induces circulatory dynamics imbalance. The morphofunctional deficiency, induced by cell death, causes proliferative processes in the form of an increasing number of double nucleated and polyploid hepatocytes.
Key words: sodium tetraborate, liver, degenerated hepatocytes, double nucleated cells, polyploid hepatocytes.
more than 1.0 mg of boron per day has a negative impact on health. Increasing boron intake by consuming a diet rich in fruits, vegetables, nuts enhances health and wellbeing [2]. M. Kabu and co-authors [1, p:255] determined that borax in lower doses didn't cause any histological changes in kidneys, large intestine, liver and stomach. Marked edema, inflammatory migration of cells and formation of new vessels were observed during administration of high dose of borax.
One of the target organs of xenobiotics is the liver where under the influence of toxic substances marked disturbances of tissue structures are developing manifesting by dystrophy, bloodstream widening, hepatocytes regeneration disorder[3].
Liver being the largest gland of the organism and the first organ receiving metabolic substratum and nutritious substances from food receives double blood irrigation enriched by oxygen due to its hepatic artery and enriched by nutritious substances received from portal vein. For this reason liver is undergone to constant influence of toxic substances that are observed, degraded or conjugated [4]. Toxic reactions are realized through direct damaging action on liver cells and characterized distinctly by observed dependence on dose of substances entered into organism and also on the duration of its influence. Therefore it is highly actual to establish the level of damaging action of toxic substances on liver from its dose and duration of action.
Materials and methods of research. Study was carried on 10 intact, 10 control, 10 experimental white outbred male rats. The investigation materials were the pieces of the largest left side lobe of the liver. Sodium tetraborate

1-2 ml in a dose150 mg/kg (1/30 LD50) was intragastrically in aphysiological solution administered to experimental animals daily during two months, except the days off. Control animals received introventricularly 1-2 ml of physiological solution in the same period. Removing the animals from the experiment was realized by decapitation method. All manipulation on animals were done on the basis of ethnic committee permission of West Kazakhstan Marat Ospanov State Medical University (protocol No. 1 dated December 25, 2009). Paraffin sections of 7-8 mkm thickness were stained with hematoxylin and eosin and according to van Gieson after histological diagnosis. In increasing 400 times in the histological sections, using the morphometrical grid overlay method (grids 256 points), then the quantity of double nuclear, polyploid and degenerating cells were counted. Statistic processing of investigation findings was carried out according to the Statistica 10 software. Analysis of results was done using arithmetical mean, moderate error, Student's criterion. Differences between average indices in P<0.05 were considered as significant.
Goal of research is to study the influence of tetraborate sodium on liver structure.
Research objective is to study the structure of liver when sodium tetraborate action on rat's organism.
Research results and discussion. The normal liver mass index of rat was 41.7±2.14, which equals to more than 4% of the animal's weight. Light and dark hepatocytes were clearly visible in hepatic lobules. The center of the classic lobule usually contains light hepatic cells, while the periportal area contains dark hepatocytes (Figure 1). In singular cases, the periportal third of the hepatic lobule contains light hepatocytes.
The mean diameter of light hepatocytes, located in the center of the lobule, exceeds the diameter of peripheral cells and is 25-27 |im (Figure 1b).

intoxication, blood stasis was observed - the blood filling of the central vein where parietal fibroblasts are located and sinusoidal dilatation (Figures 2a, b). However, stasis was not observed in certain central veins of hepatic lobules (Figure 3). Light hepatocytes, located around the central vein, are mostly degenerated (Figure 2e, Figure 3c, Figure 4d), while their percentage is 12.3±1.24%. They did not occur to intact and control animals. In addition, an increase in the number of double nucleated cells up to 12.7±1.75% is observed after chronic intoxication (Figure 2b, Figure 3b, Figure 4c). There is an increase in the number of polyploid cells, if their number in the control group was 2.2±0.12%, then in the experimental group their number reached 4.3±0.27% (Figure 2d).
An accumulation of fibroblasts is observed around triads, located in the periportal area (Figure 5a). If the central veins were filled with blood, then extended peritubular spaces were observed around bile ducts (Figure 5).
After 2-months borax intoxication, the relative weight of rat liver was reduced, with a mass index reduction to 36.3±2.53, which equaled to 3.6% of the animal's weight. In the control group, the index was 42.5±2.37, which equaled to 4.2% of the animal's weight.
While generalizing the research results, it should be noted that the presence of dark and light hepatocytes observed under the physiological conditions of animal life, could be explained morphologically by the difference in the content and distribution of the main cell organelles. According to M.V. Khodakova [5], the difference between dark and light hepatocytes is explained by a more developed granular endoplasmic reticulum and a greater number of mitochondria. Their cytoplasm has more glycogen, which indicates the prevalence of the synthetic process. Morphological differences between dark and light hepatocytes match their heterogeneity with regard to lipid, carbohydrate and xenobiotic metabolism. Structural and functional
