Background and Aim: The present study investigated the influence of liver tumor structure on life expectancy in dogs. Diseases of the liver comprise 5-25% of all non-communicable diseases in dogs, and primary hepatic tumors account for 0.6-1.3% of tumors. This research aimed to study the post-operative life span of animals with primary or metastatic tumors of the liver. Materials and Methods: During the study period, 7124 oncological operations were performed in our clinic. In total, 128 liver tumors were detected in live animals, while 323 were detected posthumously. Forty animals underwent surgery for various liver tumors. In dogs with primary liver tumors, the average age was 11.9 years and the average body weight was 15.5 kg, while in dogs with liver metastases, the mean age was 11.4 years and the average body weight was 24 kg. Results: The ratio of males to females among dogs with primary liver tumors was about 1:1 (ten females and nine males), while that among dogs with metastatic liver damage was clearly predominantly female (14 females and two males) because females often undergo surgery for cancerous mammary glands or ovaries. Conclusion: The size of tumors and the number of affected lobes had a significant effect on the post-operative life span. With a tumor size of

Aim: The purpose of this work was to study the dynamics of structural manifestations of acute cases of postpartum endometritis in cows. Materials and Methods: The light and electron microscopy methods were used when studying structural changes in the endometrium in case of postpartum endometritis in seven cows. Sections of endometrial specimens for light microscopy, 5-7 μm thick, were stained with hematoxylin and eosin and also by Van Gieson's. For electron microscopy, semi-thin sections were stained with Azur-2 in combination with basic fuchsin, as well as contrasting by lead citrate and uranyl acetate. Results: As a result of the study, we have established the following: Necrobiosis of the epithelial layer of the mucosa, cellular infiltration with shaped elements of blood in the functional layer, swelling of the cells of the uterine gland, and single microbial cells on the surface of the mucosa. We have noted edema of the stroma of the functional layer of the endometrium, swelling of the epithelial layer of the endometrial mucosa, and swelling of fibroblastic and lymphoid cells. Ultrastructural changes in endometrial cells in case of acute postpartum endometritis in cows are accompanied by the destruction of microvilli on the apical surface of the epithelium, an abundance of coccal microflora on the surface of the epithelium, necrobiosis of epithelial cells, and partial edema of the nucleus, and cytoplasm of the histiocyte. Conclusion: We had established that acute purulent-catarrhal dystrophic processes were observed in the structural organization of the endometrium. In the depth of catarrhal mucus on the surface of the endometrium, there was an abundance of bacterial flora, with diplococci being prevalent. In ultrastructural organization of the endometrium, we observed deep dystrophic and necrobiotic processes in the parenchyma and endometrial stroma, as well as exudative processes with a change in the integrity of the microcirculatory bed. Thus, to prevent an inflammatory process from turning into a latent form, it is necessary to detect acute postpartum endometritis promptly using diagnostic methods taking into account the obtained parameters of the dynamics of structural changes in the uterine tissues.

In order to reduce the time of wound healing of the operated animals and the prevention of complications, we have developed the device of the wound notched hook form by increasing its non-invasive and handling, as well as the retractor for moving apart organs in the abdominal cavity to facilitate the surgical approach, sufficient visibility and control designated and recorded organs by it during surgery. Wound notched hook consists of framing handle with a longitudinal through hole connected to the retaining ring, while on the other side of the fixation ring is formed with the rod with operating element consisting of bent tines. Unlike the commonly used wound notched hook its free ends of the tines are made with drop-shaped thickening for their non-invasive reliance on soft tissue. Application of the developed wound hook notched allows you to: achieve fast and safe placing of the free end tines into the operating cavity as well as the smooth and safe removal of wound hooks notched outside the operating cavity or wound; avoid undue injury tissue of the operated animal. Upgraded retractor comprises a carcass handle connected to the retaining ring, while on the other side of the fixation ring formed conically widening plate bent at right angles and forming the operating element in the form of restrictive platforms. Unlike the conventional retractor restrictive site are made through identical longitudinal rectangular openings arranged parallel to each other and to the longitudinal axis of the retractor for moving apart organs. Developed retractor allows you to: reduce the overlapping area of the continuous operating member retractor in the side aperture of the abdomen; eliminate long clamping organs between the retractor and lateral aperture of the abdomen; reduce the time for the operation; facilitate ligation; reduce the weight of the retractor for moving apart organs; improve the usability of the tool. Together, these tools significantly improve performance with auxiliary surgical instruments and improves the safety of working with them.

In this work the study of the structure and features of development in the ontogeny of the bone marrow of Guinea fowls of the Volga white breed. Bone marrow is located in the cells of the spongy substance, and with age, its absolute mass increases, and the relative mass is reduced. In the period from 1 to 60 days age was observed the highest content of bone marrow in the skeleton of a Guinea fowl. In males the number of bone marrow more than females, in average by 1.5-2%. The bulk of the marrow from the Guinea fowls at the age from 1 to 90 days are in the peripheral skeleton, more than 55% in the pelvic limbs. The axial skeleton of the Guinea fowl at this age contains about one third of all bone marrow and much of it is concentrated in the spinal column. With age, the saturation of the axial skeleton bone marrow sharply increases and reaches to 48.1% of the total content in the skeleton of a Guinea fowl. The peak saturation of the skeleton by bone marrow observed in the first two months of life Guinea fowls. Then this figure was relatively stable until the age of 90 days varies slightly. With 180 day age, there is a sharp drop of saturation of the skeleton of a Guinea fowl bone marrow. At one year of age, the figure is only 57-59% of the saturation of the skeleton by bone marrow at the age of 90 days. With age, red marrow is replaced by yellow bone marrow. Microscopy of smears of bone marrow of individual fat cells found in red bone marrow in the daily age. At the age of 60 days there is a replacement of red bone marrow yellow 20-28%, and in 90 days in 40%. At the age of 365 days, almost the entire bone marrow is represented by yellow.

The sharp form of ornithosis at parrots is followed by a hypothermia (38,0-39,9 °C), organism exhaustion and intoxications. Prior to treatment by antibiotics and prevention of a lethal outcome at treatment of birds applied the preparation “Temperin” which led to normalization of body temperature (40-42 °C) within 1-3 days. When using of the complex scheme of treatment of ornithosis developed by us efficiency (convalescence of a bird) reaches 60%, which depends on time of the request for the help and weight of a condition of a bird, the best result is revealed at the beginning of therapy within three days from emergence of the first symptoms of a disease.
