The study aimed to determine the characteristic changes in alimentary lymphoma in cats during ultrasonography, pathoanatomic and cytological examination of biopsy material. The survey objects are cats with gastroenterological disorders with suspected alimentary lymphoma of different ages and genders. The diagnosis was made based on a clinical examination according to generally accepted methods, laboratory blood examination, ultrasound examination, pathomorphological examination of the intestinal walls and lymph nodes, and cytological examination of the lymph node material obtained by the TIAB method. The authors carried out the material sampling for cytological examination using percutaneous fine needle aspiration (FNA) biopsy under ultrasound control on the Mindray Z6 Vet apparatus. In addition, the authors conducted pathological and cytological studies in the Vet Union laboratory. When analyzing ultrasound examination in cats diagnosed with alimentary lymphoma, hepatomegaly, 1% ascites, 3% hydrothorax, 3 % increase in mediastinal lymph nodes, 7% splenomegaly, 16% violation of differentiation of intestinal layers, 16% violation of differentiation of intestinal layers, 29% increase in mesenteric lymph nodes, 29 % thickening of intestinal walls were observed in 12% of cases. Cytological examination revealed rounded, large, separately located cells. The population is monomorphic. During a histological study in the intestinal wall, adjacent fatty tissue of the omentum, and lymph node tissue, there is a highly cellular invasive formation constructed from diffuse layers of rounded lymphoid neoplastic cells with a scanty fibrous stroma. The most characteristic ultrasound findings are the thickening of the intestinal walls and an increase in mesenteric lymph nodes.
This article examines the effectiveness of the treatment of rickets in young camels bred in the Republic of Kalmykia with tricalcium phosphate and tricalcium phosphate with granuvite E. To determine the biogeochemical features of the Justinsky and Yashkulsky districts of the Republic of Kalmykia, we carried out an analysis of diets for nutritional value and balance, and a study of the soil, water, feed, and macronutrient content of camels’ blood. The article presents data from the clinical examination, and the clinical, hematological and biochemical blood tests carried out before, during and after therapy. To enrich the body of experimental camels with missing macrocells (calcium, phosphorus) and vitamins (tocopherol), an experiment was carried out using tricalcium phosphate and tricalcium phosphate with granuvite E. From an economic point of view, it is more appropriate to use tricalcium phosphate (17.82 rubles) than tricalcium phosphate with granuvite E (15.54 rubles). However, as confirmed by laboratory studies (hematological and biochemical parameters), from a therapeutic point of view, the use of tricalcium phosphate for one month does not completely restore calcium-phosphorus imbalance, unlike when tricalcium phosphate is used with granuvite E. The use of tricalcium phosphate and granuvite E for therapeutic purposes once a month for young camels of 120 g and 2 g, respectively, has high therapeutic efficacy in treating osteodystrophy and normalizes the calcium-phosphorus ratio. Keywords: young camels, therapy, mineral metabolism, tricalcium phosphate
One of the most common diseases of pigs in large pig enterprises is enzootic pneumonia. The main etiological agent causing enzootic pneumonia is Mycoplasma hyopneumoniae. Mycoplasmas have minimal virulence, but they increase the susceptibility of pigs to secondary infections. In association with other microorganisms, Mycoplasma hyopneumoniae enhances its pathogenic effect, which makes the course of the disease more severe, often leading to the death of animals. Blood tests were performed to study the changes in morphological and biochemical parameters during the development of infection caused by Mycoplasma hyopneumoniae. Experimental groups of animals were formed, consisting of healthy as well as infected and ill pigs of different ages (2, 3, and 4 months), in which the pathogen M. hyopneumoniae was detected by polymerase chain reaction. The following hematological changes were revealed in the piglets suffering from respiratory mycoplasmosis: erythropenia, leukopenia, increased blood sedimentation rate (BSR), hypoproteinemia, hypoalbuminemia, increased activity of alanine aminotransferase and alkaline phosphatase, increased urea, and hyperglycemia. Keywords: pigs breeding; pneumonia; biochemical parameters; morphological parameters
