The main purpose of the study was to determine the effect of egg mass and egg weight groups (group I eggs under 160 g, group II egg mass 160 g to 180 g and group III eggs over 180 g) on incubation results, loss of egg weight (moist) during incubation, gosling hatchability and the relative share of the gosling in the egg mass. Eggs with mass between 160 g and 180 g (group II) demonstrated the highest fertilisation rate (91.28 %) and the highest hatchability out of the number of incubated eggs (83.14 %), while the eggs from the group I (lighter than 160 g) showed the highest number of gosling hatchability out of the number of fertilised eggs (91.08 %). The lowest embryo mortality was that of the group I (5.17 % and 6.06 %), while the highest is reported for the group III (14.29 % and 16.67 %). The lowest relative loss of egg mass (moist) by day 25 of the incubation period was established for the group I eggs (10.98 %), and the highest for the group III (11.71 %), with a statistically significant (P Lass Than 0.01) difference of -0.73 %. Other differences were not statistically significant (P>0.05). Gosling percentage in the egg mass was significantly higher (P Lass Than 0.001) in the group III of incubated eggs (67.81 %) than in the group II (66.61 %) and the group I (65.24 %).

The objective of this project was to find to what extent loss of weight in the digestive tract might affect tumor size and age in albino rats bearing Walker carcinosarcoma 256. Wet weight, dry weight, and water content were measured upon tongue, esophagus, cardiac stomach, pyloric stomach, jejunum, ileum, cecum, colon, and residual carcass (minus tumor). The animals bore tumors weighing 12 ± 6 (mean ± S.D.) % of host (minus tumor) weight after 18 ± 6 days of tumor growth (group I), 38 ± 12% after 24 ± 6 days (group II), and 93 ± 26% after 29 ± 5 days (group III) and controls were twins of the same sex. There were few significant changes in the animals of group I. In group II, there was loss of dry weight in all organs except pyloric stomach, losses being percentagewise the same as in residual carcass. Loss of dry weight of jejunum and ileum was less in rats of group III than in those of group II. In group III, loss of weight in other organs tended to be less than in residual carcass. Loss of dry weight in residual carcass was not significantly greater in the animals of group III than in those of group II. Water levels were increased in all organs of rats in groups II and III. This evidence indicates that rats of group III may have lived longer after tumor implantation, lost no more carcass weight, and bore larger tumors because they had lost weight in the small bowel at a lesser rate than had the rats of group II.Further studies revealed that lipid shifts were in general less marked in organs which had lost the least weight. In animals bearing large tumors, percentage loss of neutral fat was less in most organs of the digestive tract than in the residual carcass. Increases in the levels of cholesterol and phospholipid were less in pyloric stomach and small bowel than in other organs of the digestive tract. Shifts in the amount of nonlipid dry weight and in levels of lipids and water were in general less in pyloric stomach and small bowel than in other organs of the body. In these respects, pyloric stomach and small bowel resembled brain, heart, and lung. It is suggested that resistance of pyloric stomach and small bowel to the cachectic influence of the tumor may be a factor determining tumor size and length of survival of the host.

The effects of two doses of cloprostenol and two doses of flurogestone acetate sponge on the onset of oestrus, and embryo recovery and quality were evaluated. Thirty-two indigenous ewes (Wera breed) were allocated into four groups of eight. All ewes were synchronised with 100 µg (Group I) or 175 µg (Group II) cloprostenol injection, 9 days apart, or insertion of intravaginal sponges containing 30 mg (Group III) or 45 mg (Group IV) flurogestone acetate (FGA) for 12 days. The ewes were superovulated with 600 IU PMSG intramuscularly 10 days after the second cloprostenol injection or immediately after sponge removal on Day 12. After the detection of oestrus, the ewes were mated naturally at 6 and 12 h, and some ewes were inseminated laparoscopically. Embryos were recovered surgically 5 or 6 days after service. All ewes exhibited oestrus. The onset of oestrus occurred significantly (P < 0.05) earlier in FGA-treated (50.0 ± 1.5 and 48.0 ± 0.00 h) than in cloprostenol-treated groups. There were no significant differences (P > 0.05) in the mean time of onset of oestrus (50.0 ± 1.5 and 48.0 ± 0.00 h) between the two doses of cloprostenol. The mean number of corpora lutea (8.1 ± 1.26) and embryos recovered (6.1 ± 1.00) was significantly (P < 0.05) higher in ewes treated with 45 mg FGA than in ewes treated with cloprostenol. Embryo recovery rate was significantly (P < 0.05) higher in ewes treated with 45 mg FGA (75.4%) than in other groups (41.7% and 51.6% in 100 μg and 175 μg cloprostenol- and 52.7% in 30 mg FGA-treated groups, respectively). Fertilisation rate was 93.3% in ewes given 100 µg cloprostenol, whereas other groups showed 100% fertilisation rate. The highest percentage (100%) of Grade 1 embryos was in FGA groups. In conclusion, despite FGA protocol presenting superior results, cloprostenol protocol was equally efficient in synchronising oestrus. The embryo recovery rate was better after 45 mg FGA than 30 mg FGA or after either dose of cloprostenol.

We set the aim to study the effect of the blood influx of large gray geese and legart geese breeds on the productive qualities of the obroshyno breed group of geese in the third generation) and the legarts that have been highlighted in our previous publications. With the descendants of these crosses breeding and breeding work was conducted in the direction of breeding and productive qualities improvement. For our research, four groups of 50 birds each were compiled from the livestock of geese, which were kept separately for the breeding and egg laying periods (from January to May) to ensure proper feeding and retention. The average geese live weight at the beginning of oviposition were: females OS – 6.25 kg, OB – 6.35, OS ♀ (OS ♀ x BC ♂) – 6.45, OB ♀ (OB ♀ x legart) – 6.5; males OS – 7.15 kg, OB – 7.35, OS ♂ (OS ♀ x BC ♂) – 7.45, OB ♂ (OB ♀ x legart ♂) – 7.50 kg. The duration of oviposition was higher in purebred geese (groups I and III) compared to domestic geese (groups II and IV). The average oviposition of the group I geese was highest – 41.0 pcs/head and was dominated by the group II geese by 1.2%. The weight of OS of geese of group III amounted to 40.6 pcs/head and was dominated by local geese of group IV by 2.9%. However, domestic geese (groups II and IV), by weight of eggs, outperformed purebred geese (groups I and III) by 2.1 and 4.5%, respectively. The study of incubation qualities of eggs shows that the fertilization in purebred AB and OS geese (groups I and III) was 83.9% and 83.0%, and the analogues from II and IV groups prevailed by 0.4 and 0.5%, respectively. The higher hatchability of the geese was in hybrid geese (groups II and IV) than in purebred OBS and geese OS (groups I and III). On the basis of the conducted researches the following conclusions were made: 1. The productivity of geese AB of the breed group (group I) is characterized by the following performance indicators: oviposition – 40.6 pcs. per head; egg weight – 153.2 g; fertilization – 83.5%; deductibility – 71.8%; live weight of geese at 9 weeks of age – males 4.05 kg, females – 3.67 kg; conservation – 87.0%. 2. Local geese of OB x legart (group II) had lower productivity rates: by 2.9%, they had a low fertility rate of 0.5%; fertility – 1.5%; live weight of geese at 9 weeks of age: males – 6.7%, females – 4.6%; conservation – 2.0%; at higher egg mass by 2.1%. 3. Geese of the OS of the breed group (group III) are characterized by the following performance indicators: oviposition – 40.6 pcs. per head; egg weight – 153.2 g; fertilization – 83.0%; excretion rate – 71.0%; live weight of geese at 9 weeks of age – males 4.05 kg, females – 3.67 kg; conservation – 87.0%. 4. Local geese OS x ВS (group IV) are characterized by lower indicators, respectively: with a yield of 2.9%, higher fertilization – 0.5%; with a yield of 1.5%; live weight of geese at 9 weeks of age: males – 6.7%, females – 4.6%; conservation – by 2.0%; at higher egg mass by 4.5%.

SummaryMost anticardiolipin antibodies (ACA) associated with antiphospholipid syndrome (APS) are directed against epitopes expressed on β2-glycoprotein I (β2GPI). Despite a good correlation between standard ACA assays and those using purified human β2GPI as the sole antigen, some sera from APS patients only react in the latter. This is indicative of heterogeneity in anti-β2GPI antibodies. To characterize their reactivity profiles, human and bovine β2GPI were immobilized on γ-irradiated plates (β2GPI-ELISA), plain polystyrene precoated with increasing cardiolipin concentrations (CL/β2GPI-ELISA), and affinity columns. Fluid-phase inhibition experiments were also carried out with both proteins. Of 56 selected sera, restricted recognition of bovine or human β2GPI occurred respectively in 10/29 IgA-positive and 9/22 IgM-positive samples, and most of the latter (8/9) were missed by the standard ACA assay, as expected from a previous study. Based on species specificity and ACA results, IgG-positive samples (53/56) were categorized into three groups: antibodies reactive to bovine β2GPI only (group I) or to bovine and human β2GPI, group II being ACA-negative, and group III being ACA-positive. The most important group, group III (n = 33) was characterized by (i) binding when β2GPI was immobilized on γ-irradiated polystyrene or cardiolipin at sufficient concentration (regardless of β2GPI density, as assessed using 125I-β2GPI); (ii) and low avidity binding to fluid-phase β2GPI (Kd in the range 10–5 M). In contrast, all six group II samples showed (i) ability to bind human and bovine β2GPI immobilized on non-irradiated plates; (ii) concentration-dependent blockade of binding by cardiolipin, suggesting epitope location in the vicinity of the phospholipid binding site on native β2GPI; (iii) and relative avidities approximately 100-fold higher than in group III. Group I patients were heterogeneous with respect to CL/β2GPI-ELISA and ACA results (6/14 scored negative), possibly reflecting antibody differences in terms of avidity and epitope specificity. Affinity fractionation of 23 sera showed the existence, in individual patients, of various combinations of antibody subsets solely reactive to human or bovine β2GPI, together with cross-species reactive subsets present in all samples with dual reactivity namely groups III and II, although the latter antibodies were poorly purified on either column. Therefore, the mode of presentation of β2GPI greatly influences its recognition by anti-β2GPI antibodies with marked inter-individual heterogeneity, in relation to ACA quantitation and, possibly, disease presentation and pathogenesis.

<p class="p1"><span class="s1"><strong>Background:</strong> The inspiratory oxygen fraction (FiO<sub>2</sub>) is usually set between 60% and 100% during conventional extracorporeal circulation (ECC). However, this strategy causes partial oxygen pressure (PaO<sub>2</sub>) to reach hyperoxemic levels (&gt;180 mmHg). During anesthetic management of cardiothoracic surgery it is important to keep PaO<sub>2</sub> levels between 80-180 mmHg. The aim of this study was to assess whether adjusting FiO<sub>2</sub> levels in accordance with body temperature and body surface area (BSA) during ECC is an effective method for maintaining normoxemic PaO<sub>2</sub> during cardiac surgery.</span></p><p class="p1"><span class="s1"><strong>Methods:</strong> After approval from the Ethics Committee of the University of Acıbadem, informed consent was given from 60 patients. FiO<sub>2</sub> adjustment strategies applied to the patients in the groups were as follows: FiO<sub>2</sub> levels were set as 0.21 × BSA during hypothermia and 0.21 × BSA + 10 during rewarming in Group I; 0.18 × BSA during hypothermia and 0.18 × BSA + 15 during rewarming in Group II; and 0.18 × BSA during hypothermia and variable with body temperature during rewarming in Group III. Arterial blood gas values and hemodynamic parameters were recorded before ECC (T1); at the 10th minute of cross clamp (T2); when the esophageal temperature (OT) reached 34°C (T3); when OT reached 36°C (T4); and just before the cessation of ECC (T5).</span></p><p class="p1"><span class="s1"><strong>Results:</strong> Mean PaO<sub>2</sub> was significantly higher in Group I than in Group II at T2 and T3 (<em>P</em> = .0001 and <em>P</em> = .0001, respectively); in Group I than in Group III at T1 (<em>P</em> = .02); and in Group II than in Group III at T2, T3, and T4 <br /> (<em>P</em> = .0001 for all). </span></p><p class="p1"><span class="s1"><strong>Conclusion: </strong>Adjustment of FiO<sub>2</sub> according to BSA rather than keeping it at a constant level is more appropriate for keeping PaO<sub>2</sub> between safe level limits.

The article presents the comparative analysis of the state of the cervix in women with endometrial polyps and micropolyps. Patients and methods. The study involved 130 patients aged 18-35 years: 70 patients with endometrial polyps (group I), 30 patients with micropolyps (group II) and 30 patients of the control group (group III). Results. According to the anamnesis of women in the I group were significantly more frequent diseases of the cervix, which corrected physical surgery methods, in particular cryodestruction. In group II, the representatives of these indicators were similar to healthy. Normal colposcopic picture met significantly less frequently in patients and I, and II group. The differences in the incidence of HPV high oncogenic risk in all groups were not statistically significant. Conclusion. Destructive methods used in the detection of any changes in the cervix are often overly aggressive, form scars and contributing to inflamaciones process. In the chain of events leading to the formation of PE, cervical pathology and its correction can take the basic place. Key words: endometrial polyp, micropolyps, chronic endometritis, uterine cervix, colposcopy.

Изучено влияние кормовой добавки в форме индивидуальных болюсов Метраболь на возможность снижения негативного влияния субклинического кетоза (СКК) и результативность искусственного осеменения высокопродуктивных молочных коров в посттранзитный период. Животные были подобраны по принципу условных аналогов и разделены на 3 группы в зависимости от концентрации β-оксимасляной кислоты в их крови. В I группе (n=18) у коров не было СКК, концентрация кислоты составляла <1,0 ммоль/л, во II группе (n=21) у животных зарегистрирован СКК, концентрация кислоты — 1,0…1,4 ммоль/л. С целью поиска решения по снижению негативного влияния СКК на репродуктивные показатели была сформирована III группа коров, переболевших СКК (n=24) с концентрацией β-оксимасляной кислоты в крови 1,0…1,4 ммоль/л, но с использованием болюсов, применяемых для ускоренного восстановления репродуктивной функции коров после отела. Важной составляющей опыта явилось то, что к моменту гормональной синхронизации у коров всех 3 групп фиксировалось отсутствие СКК (снижение β-оксимасляной кислоты до уровня <1,0 ммоль/л). Для синхронизации полового цикла выбрана схема Пресинх-овсинх. Установлено, что гормональная синхронизация животных, перенесших СКК, в сравнении со здоровыми, не позволяет снизить негативное влияние данного нарушения обмена веществ. Во II группе у животных зафиксированы самые низкие репродуктивные показатели (количество использованных доз; индекс осеменения, сервис-период; время от первого до успешного осеменения; результат первичного осеменения; количество животных, осемененных 3 и более раз). В III группе применение болюсов позволило, в сравнении с животными II группы, не только избежать отрицательного воздействия СКК, но и превзойти по изучаемым параметрам животных из I группы. The effect of the feed additive in the form of individual boluses Metrabol on the possibility of reducing the negative effect of subclinical ketosis (CCK) and the effectiveness of artificial insemination of highly productive dairy cows in the post-transit period was studied. The animals were selected according to the principle of conditional analogs and divided into 3 groups depending on the concentration of β-hydroxybutyric acid in their blood. In group I (n=18), the cows did not have SSC, the acid concentration was <1.0 mmol/L, in group II (n=21), SSC was registered in animals — 1.0...1.4 mmol / L. In order to find a solution to reduce the negative effect of CCB on reproductive indices, a group III of cows was formed who had CCB (n = 24) with a concentration of β-hydroxybutyric acid in their blood of 1.0...1.4 mmol/L, but using boluses, used to accelerate the restoration of the reproductive function of cows after calving. An important component of the experiment was that by the time of hormonal synchronization, cows of all 3 groups had no SSC (decrease in β-hydroxybutyric acid to a level of <1.0 mmol/L). To synchronize the sexual cycle, the Pressinh-ovsinh scheme was chosen. It was found that hormonal synchronization of animals that underwent SSC, in comparison with healthy ones, does not allow reducing the negative effect of this metabolic disorder. In group II, animals had the lowest reproductive indices (number of doses used; insemination index, service period; time from first to successful insemination; result of primary insemination; number of animals inseminated 3 or more times). In group III, the use of boluses made it possible, in comparison with animals of group II, not only to avoid the negative effect of SSC, but also to surpass the animals from group I in terms of the studied parameters.

The serum progesterone and estradiol profiles during synchronization of estrus by buck effect and PGF2α treatments were monitored in Surti does. Total eighteen non-pregnant does selected were evenly divided into 3 groups, 6 does in each group. The does of Group I were teased with a sexuallyactive- apronized buck; and those of Group II were treated with PGF2α, i.e., Inj. Lutalyse® @ 7.5 mg/doe IM twice 11 days apart, while the Group III served as untreated control. Blood samples were collected from all the animals on day 0 (before 1st PGF2α injection), 3rd day (during treatment), 11th day (before 2nd PGF2α injection), 14th day (after treatment) and 40th day (post-service) by jugular vein puncture. The serum separated was stored at -20°C till further analysis. In all the three groups, 83.33% does, conceived at first service in the sampling cycle. The overall mean serum progesterone concentration of Group I does (5.82±0.72 ng/ml) was significantly higher (p less than 0.01) as compared to Group II (2.93±0.38 ng/ml) and III (2.88±0.30 ng/ml). Similarly, the overall mean serum progesterone concentration of Surti does on day 0 (2.65±0.46 ng/ml), 3rd (2.56±0.80 ng/ml), 11th (4.45±0.84 ng/ml) and 14th (3.40±0.63 ng/ml) did not differ significantly, but the overall mean level at day 40 (6.31±0.45 ng/ml) was significantly (p less than 0.01) higher, because most of animals became pregnant at that time. The overall mean serum oestradiol-17β levels of Group I (24.40±2.98 pg/ ml) was significantly higher (p less than 0.01) than in Group II (15.77±1.77 pg/ml) and III (12.21±1.45 pg/ ml). On the other hand, the overall mean serum oestradiol-17β levels of Surti does on day 0 (12.89±1.21 pg/ml), 3rd (15.84±1.74 pg/ml), 11th (14.81±1.96 pg/ml), 14th (22.15±2.97 pg/ml) and 40th (21.64±5.16 pg/ml) did not differ significantly (p>0.05) and the slightly higher overall mean level found at 40th day might be the influence of the non-pregnant does at first service in the cumulative animals. The hormonal profile reflected the initiation of cyclicity and establishment of pregnancy in treated and control animals.
