The purpose of work is improving the efficiency of fertilization dog breed French Bulldog. The results of cytological examination of vaginal mucus in dogs at different periods of the sexual cycle. This will determine the optimal time for insemination. As a result of vaginal smear cytology of dogs among the signs of days favorable for breeding are the days when cytological smears appear more than 60% of the surface of pycnotic cells, a small amount of red blood cells and white blood cells, superficial cells are arranged in groups of 4-6 cells or clusters in the form of tiles. Proestrus phase corresponds to the presence of only of basal cells in a smear at the beginning. Then trend towards a decrease of intermediate and superficial cell growth. In the smears are found red blood cells and white blood cells. The duration of the stage of 6-8 days. Estrus phase is characterized by the appearance in the smear of more than 60% of the surface of pycnotic cells, a minor amount of red blood cells and white blood cells. The duration of the stage of 10-11 days. It was found that in dogs the most optimal days for mating are 3-4 day estrus. A smear diestrus phase accompanied by the presence of abrupt changes in the cellular structure. The picture a smear vaginal mucus in diestrus are signs are reducing the number of superficial cells, and increasing the number of intermediate cells; changes in the nature and appearance leukocyte, smear of mucus becomes turbid, dusky background. The duration of stage about 60 days. In anestrus cytological picture of the mucous membrane is stable. There are small cell in smears, revealed basal epithelial cells, can occur intermediate unit cells and leukocytes. The duration of the stage about 123 days.

Many works of domestic and foreign scientists are devoted to the study of etiological factors, pathogenesis, as well as the development of effective methods of diagnosis and therapy for symptomatic infertility of cows, however, insufficient attention is paid to cytological examination of the genital organs.So the goal of our work was to study the cytology of vaginal mucus at the symptomatic form of infertility of cows. The article presents the cytological composition of vaginal mucus from the mucous membrane of the caudal section of the cervix, the lateral surface of the vagina and the dorsal wall of the vaginal vestibule. Research was carried out with 5 groups of cows 4–5 years old cows 6 animals in each, weighing 500–600 kg, with an average productivity of 7500 kg of milk per lactation. The tests were cows were on the 18–24 day after insemination and during the sexual cycle braking, research of the joint course of uterus and hypotension of the ovarian, the presence of persistent corpus luteum and subclinical chronic endometritis, cysts and persistent corpus luteum of the ovarian body. For sub-clinical chronic endometritis, basal cells (32–41 %) are found in wet prep with vaginal mucosa, which are arranged in layers, parabasal (22–6 %) and superficial (5–21 %), but more interstitial (37–66 %), and bare neutrophil nuclei. According to hypofunction of ovaries in vaginal smears, neutrophils, vacuoles in interstitial cell nuclei (44–56 %), basophilic cells (30–43 %), superficial cells (20–21 %), parabasal cells (3–6 %). Basal cell hypofusions were (3–43%), parabasal (3–6 %), interstitial (44–56 %), superficial (20–21 %), and bilateral (12–26 %) (4–5 %) (36–55 %) and (30–33 %). It should be noted that for the functional state of the body, the cells from the cervix are flat. In addition, the drug contains single white blood cells with light cytoplasm without signs of phagocytosis. They are structurally similar to cells of vaginal smear. During the esrtus, the smear is dominated by interstitial and surface cells and white cells, and in the follicular proliferative phase, the number of surface cells increases, while the ovulator phase is characterized by the pronounced maturation of the cells, they are flat and spaced apart.

SummaryThe effect of red blood cells, rbc, and shear rate on the ADPinduced aggregation of platelets in whole blood, WB, flowing through polyethylene tubing was studied using a previously described technique (1). Effluent WB was collected into 0.5% glutaraldehyde and the red blood cells removed by centrifugation through Percoll. At 23°C the rate of single platelet aggregtion was upt to 9× greater in WB than previously found in platelet-rich plasma (2) at mean tube shear rates Ḡ = 41.9,335, and 1,920 s−1, and at both 0.2 and 1.0 µM ADP. At 0.2 pM ADP, the rate of aggregation was greatest at Ḡ = 41.9 s−1 over the first 1.7 s mean transit time through the flow tube, t, but decreased steadily with time. At Ḡ ≥335 s−1 the rate of aggregation increased between t = 1.7 and 8.6 s; however, aggregate size decreased with increasing shear rate. At 1.0 µM ADP, the initial rate of single platelet aggregation was still highest at Ḡ = 41.9 s1 where large aggregates up to several millimeters in diameter containing rbc formed by t = 43 s. At this ADP concentration, aggregate size was still limited at Ḡ ≥335 s−1 but the rate of single platelet aggregation was markedly greater than at 0.2 pM ADP. By t = 43 s, no single platelets remained and rbc were not incorporated into aggregates. Although aggregate size increased slowly, large aggregates eventually formed. White blood cells were not significantly incorporated into aggregates at any shear rate or ADP concentration. Since the present technique did not induce platelet thromboxane A2 formation or cause cell lysis, these experiments provide evidence for a purely mechanical effect of rbc in augmenting platelet aggregation in WB.

Purpose: to study hematological parameters of blood in bulls-producers of dairy breeds on the day of semen collection in the Udmurt Republic after a long winter period of operation, depending on the breeds, age and place of selection.Materials and methods. The work was performed at the Federal Research Center for Animal Husbandry named after Academy Member L. K. Ernst on the basis of AO "Udmurtplem" of the Udmurt Republic in the period from 2020 to 2021 on dairy bulls (n=20) aged 15-69 months, including a purebred Holstein breed of domestic selection (n=6), a Holstein black-and-white breed of European selection (the Netherlands, n=6), a black-and-white breed with blood transfusion on Holsteins on at the level of 94-98% (n=8). The content of white blood cells, red blood cells, hemoglobin and hematocrit, depending on age and breed, was studied on the ABC VET hematological analyzer on the day of taking the seed.Results. It was found that on average, in 20 bulls aged 15-69 months, the level of white blood cells was at the level of reference values of 8.8±0.25 x 109/l, red blood cells 10.3 x 1012/l, which is 50% more than the reference values. The concentration of hemoglobin is 128.0±2.92 g/l, hematocrit is on average 54.3%, with a norm of 24-46%. Breeding bulls at a reliable level, differing in age, showed that some animals had high indicators for red blood cells of 10.3±0.26 x 102, for hematocrit of 54.3% against 24-46% of reference values. Also, according to hematological indicators, there was a tendency to increase the concentration of hemoglobin and hematocrit in European-bred bulls.Conclusion. The study of the variability in hematological parameters depending on the selection showed that there is no significant difference in leukocytes and all indicators are at the level of reference values, and in erythrocytes more than 50% than the highest indicators. The highest hemoglobin values were at the level of 141-156 g/l instead of 128 g/l according to the highest reference values. Hematocrit also showed high max values in all groups in comparison with the reference values of 59-66% versus 46% in the norm. It is necessary when analyzing hematological blood parameters in addition to the average statistical indicators (M+m) also, monitor the variability (min-max) in order to obtain more objective information.

Objective To observe the national elite male rowers blood, red blood cell activity and serum copper, zinc, calcium, magnesium and iron content of the five elements, and compared with the ordinary people. Aimed to investigate the between athletes, athletes and ordinary differences between the two sets of indicators and to explore the impact of element contents in red blood cell activity and five factors. Trying to bring two sets of indicators and specific combining ability, used in training on the monitoring function, and for the future to provide some references for further study. Methods It was included 22 athletes and 22 ordinary men, as the research object, in the collection of blood, measuring red blood cell activity in the blood content of the five elements, simultaneous measurement of physical indicators , will be doing all the data at the differences between the two groups compared to the group to do correlation analysis. The recent record of 2000m, 6000m rowing Dynamometer test results, and red blood cell activity associated with the five elements of content analysis. Results 1. Athletes indicators related to aerobic exercise were significantly higher than ordinary people. The white blood cells of athletes group were average.It shows that athletes have high aerobic capacity, while white blood cells are more stable than normal people. The members of the national rowing men's iron, magnesium content was significantly higher than ordinary group, the iron content is higher than the normal reference value; blood calcium levels were significantly lower than ordinary people, and lower than the normal reference value. The total number of red blood cells and the number of living cells was very significant positive correlation in two groups subjects; Red blood cell activity and red blood cell diameter is proportional, and red blood cell roundness in inverse proportion to the relationship; from this experiment a special ability to see red blood cell activity and there is no correlation. In both groups, hemoglobin was positively correlated with iron content, while iron was positively correlated with copper content. Conclusions 1. Increasing the number and volume of red blood cells can effectively increase the activity of red blood cells; red blood cell activity has no correlation with specific ability, and can not be used as an indicator to determine specific ability. The content of iron and magnesium in rowers is higher than that in ordinary people, which indicates that the adjustment of aerobic capacity and nerve control is very effective. The lower calcium content indicates that the injury caused by calcium loss should be prevented and the urgency of calcium supplementation should be emphasized. In training, we should pay attention to increasing hemoglobin content and aerobic capacity by supplementing iron. We can further consider the effect of supplementing copper to promote iron supplementation.

Aspartame (ASP) is one of the most widely used nonnutritive sweeteners. This study investigates the chronic effects of ASP on hematological and biochemical parameters, and its effects on the oxidative/antioxidative status in the red blood cells of Wistar albino rats. Rats were provided with ASP (40 mg/kg/daily for six weeks) in drinking water. Increased food and fluid intake was observed in the ASP-treated rats. Total body mass was significantly decreased in the ASP-treated rats. Treatment with ASP caused an increase in the concentrations of glucose, cholesterol, LDL-cholesterol, and in the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH), as well as a decrease in the levels of HDL-cholesterol in the serum. A significant decline in the number of white blood cells (WBC) was observed after ASP uptake. Based on the results we conclude that ASP induces oxidative stress, observed as an alteration of the glutathione redox status, which leads to increased concentrations of nitric oxide (NO) and lipid peroxides (LPO) in the red blood cells. Changes in biochemical parameters, lipid metabolism, as well as changes in the levels of oxidative stress markers and the appearance of signs of liver damage indicate that chronic use of ASP can lead to the development of hyperglycemia, hypercholesterolemia and associated diseases.

A study has been made of the variation in number of the blood platelets, and the red and white blood cells of white mice injected with pneumococcus extract. The blood platelets were greatly diminished after the injection, the greatest decrease usually occurring after 24 hours. Purpuric lesions usually developed when the number of blood platelets became less than 500,000 per c.mm. Regeneration of the platelets was accomplished by the 4th to the 9th day but there was an overregeneration and the return to normal did not take place until 2 weeks had elapsed. The red cells were also greatly reduced in number, but the rate of their destruction and regeneration was somewhat slower than that of the platelets. The leucocytes were slightly if at all influenced by the pneumococcus extract. Pneumococcus extracts were shown to be thrombolytic and hemolytic. Heat destroyed the activity of both the lysins in vitro. Heated extract produced purpura in mice but did not cause a severe anemia. Extracts adsorbed with either blood platelets or red blood cells showed a marked diminution in their thrombolytic and hemolytic activity in vitro. Such extracts, however, produced purpura as well as severe anemia and thrombopenia in mice.

Definite and characteristic changes occurred in the proportions of basophiles, neutrophiles and lymphocyte cells in the blood of foxes which had received Ascaris eggs. The numbers of red blood cells and the amounts of haemoglobin remained within normal limits but the proportion of basophiles rose as high as 69.5% of the total leucocyte count. This increase is apparently associated with the number of eggs given; the largest dose producing the highest proportions. The proportions of neutrophiles and leucocytes tended to fluctuate in opposite directions. An increase in the total numbers of white blood cells appears to be influenced by an increase in the proportion of basophiles.
