A study was conducted to test the hypothesis that injecting Gonadotropin-releasing hormone (GnRH) concurrently with Prostaglandin F2 alpha () followed by an injection of human Chorionic Gonadotropin (hCG), would advance follicular growth to ovulation in Holstein heifers bearing a corpus luteum (CL). After manual examination of the CL, group 1 (PGF; ) received an injection of (25 mg, im). Group 2 (PGF + GnRH; ) received an injection of GnRH (100 μg, im) immediately after an injection of . Group 3 (PGF + GnRH + hCG; ) received concurrent injections of and GnRH followed with hCG (1500 IU, im) two days later. Follicular size and day of ovulation were monitored by daily ultrasonographic examination from days 1 to 10. Blood was collected on days-7, 0 ( administration), 2, and 7. Progesterone was not different () on days-7, 0, and 2 between the experimental groups. However, it was higher () in the PGF + GnRH + hCG group on day 7 compared to PGF + GnRH heifers, but not significantly higher than the PGF. Additionally, heifers in the PGF + GnRH + hCG group ovulated earlier () than heifers in the PGF + GnRH and the PGF group. This data indicates that hCG advances follicular growth to ovulation in spite of high levels of progesterone when injected 48 h after concurrent treatments of GnRH and on heifers bearing a CL.

The present study describes a clinical trial aimed at understanding the causes of ovarian inactivity among female dromedary racing camels in the United Arab Emirates. A total of 1406 female racing camels were presented to the Aljazeera Veterinary Center during a 19-month period from September 2014 to April 2016 because of repeat breeding (as identified by camel owners). Females underwent ultrasonographic examination of the reproductive tract, as well as a manual vaginal examination. Any observed reproductive tract abnormalities were record. A percentage of 23.8 of females possessed no detectable reproductive tract abnormalities (and thus were diagnosed as typical repeat breeders). Of the remaining 76.2% of females, 59% had utero-tubal abnormalities and 41% had ovarian afflictions. The incidences of ovarian and utero-tubal affections in nulliparous and parous infertile females were 66.7 % versus 33.3 % (P<0.05) and 32.2% versus 67.8% (P<0.05), respectively. Most of the ovarian affections were due to ovarian inactivity or ovario-hydrobursitis. The incidence of ovarian inactivity and ovarian hydro-bursitis in nulliparous and parous females were 57.6% versus 13.2% (P<0.05) and 5.8% versus 18.1% (P<0.05), respectively. A subset of animals lacking ovarian activity (n=81) and cyclic control females (n=24) underwent blood sample collection. Samples were analyzed for concentrations of red blood cells, hemoglobin, total protein, copper, glucose, calcium, iron, and phosphorus. Blood concentrations of glucose were higher and blood concentrations of copper were lower in females with inactive ovaries compared with cyclic females. After exclusion of animals with poor general health, the remaining females that did not have ovarian activity (n=234) were divided into one of three treatment groups: Group 1 (n=71) received a single treatment of subcutaneous copper and intramuscular multivitamins, plus daily intravenous infusion of phosphorous for 5 days and oral minerals and vitamins daily for 7 days; Group 2 (n=104) received a single intramuscular injection of 1500 IU of equine chorionic gonadotropin; Group 3 (n=64) were treated identically to group 1 females with the exception of receiving a single intramuscular injection of 1500 IU of equine chorionic gonadotropin at the end of the 7-day treatment period; A number of 20 females was a subset of Group 3 females who failed to respond to treatment – they were treated for 10 days with an intravaginal device containing progesterone followed by a single intramuscular injection of 1500 IU of equine chorionic gonadotropin given at intravaginal device removal. Group 3 females exhibited a higher ovarian response to treatment than either Group 2 or Group 1 females which were different from one another. Conception rate was lower in Group 2 females than in Group 1 and group 3 females which were not different. Embryonic mortality was higher in Group 2 than in Group 1 and 3 females which were not different.

Aim: This study is aimed to evaluate and validate the qualitative human chorionic gonadotropin β subunit (β-hCG) test of the vaginal uid washings of pregnant women with premature rupture of fetal membranes (PROM). Materials & Methodology: A total of 60 pregnant women between 26- and 36-weeks' gestation had participated in this study. The patients with leaking from the vagina were designated Group A, the patients with no leaking from the vagina were Group B. After administering 5 cc of normal saline to posterior fornix by sterile injector, a total of 5 cc washing uid was collected. human chorionic gonadotropin were examined on the same day on collected uid and both groups were compared statistically. Result: In the current study 53.4% patients in group 1 and 60.0% patients from control group were between 19-25 years of age group. Majority of patients were unbooked in both groups. 46.6% patients in PROM group and 56.6% patients in control group presents before 34 weeks of gestation. There is no statistical signicance between two groups in terms of demographic data. Beta -HCG values in vaginal uid of Group 1 was signicantly higher than values in Group 2 with cut off value of Beta -HCG as 50mIU/dL. 83.4% patients from Group 1 (PROM Group) shows Beta -HCG value more than 50Miu/dL.

At parturition in the tammar wallaby, Macropus eugenii, the process of luteolysis involves both prostaglandin and prolactin. Prolactin alone is luteolytic, but it has been unclear whether prostaglandin F2 alpha (PGF2 alpha) is also directly luteolytic. To examine this, three groups non-pregnant animals were studied on Day 26 after removal of pouch young (the day equivalent to parturition). Group 1 (controls) received saline injections on Days 25 and 26, Group 2 received saline on Day 25 and PGF2 alpha on Day 26, and Group 3 was pre-treated with bromocriptine (Parlodel LA, Sandoz) on Day 25 and received PGF2 alpha on Day 26. For 12 h after treatment on Day 26, plasma progesterone and prolactin concentrations were determined and behaviour was recorded. Plasma progesterone concentrations remained elevated and plasma prolactin was basal throughout the sampling period in the control animals (Group 1). After treatment with PGF2 alpha (Group 2), plasma prolactin was elevated within 15 min and plasma progesterone decreased significantly (P less than 0.001) from 600 pg mL-1 (1.91 nmol L-1) to less than 200 pg mL-1 (0.64 nmol L-1) by 8 h. However, luteolysis did not occur in females pre-treated with bromocriptine on Day 25 and injected with PGF2 alpha on Day 26 (Group 3), and prolactin concentrations remained basal. All females treated with PGF2 alpha showed parturient behavior. The results clearly show that PGF2 alpha is not directly luteolytic on Day 26 of the non-pregnant cycle, but they confirm that PGF2 alpha induces the release of prolactin, which is directly luteolytic.

Repeated breeder dairy cows (96) were used in this study. They were diagnosed clinically as cases of delayed ovulation and divided into five groups according to type of treatment used post insemination. Group one which includes 28 cow (1=28) treated with 1 vial of fertagyl, (2=22) treated with 2 vials of fertagyl, (3=19) treated with 5 ml of chorionic gonadotropin, (4=17) treated with 1 vial of Nymfalom and (5=10) treated with 1 vial of chorulon. Results showed that the number of cows which did not return to estrus (responded) were 16(57.14%), 12(54.54%), 9(47.47%), 12(70.6%) and 4(40%) respectively. Treatment and insemination were repeated to a number of unresponded cows and their results revealed response of 3 cows (27.27%) from group (1=11), response of 4 cows (50%) from group (2=8), response of 3 cows (42.85%) from group (3=7), response of 1 cow (20%) from group (4=5) and response of 2 (50%) from group (5=4). Data concerning the number, type, sex and viability of the offspring born from the treated cows were included in this study. Finally we may conclude that Nymfalon showed better result in treating cases of delayed ovulation and in improving their conception and pregnancy rate. The remaining treatments were also advisable in the absence of Nymfalon. The use of the same treatment again was also beneficial in some unresponded cases.

Abstract. The aim of the present study was to examine the induction of ovulation during pregnancy, pseudopregnancy, and suckling-delayed pregnancy in mice using exogenous gonadotropins. The present results demonstrate that there are mature follicles in the ovary which can be induced to ovulate with administration of either exogenous human chorionic gonadotropin (hCG) or luteinizing hormone (LH) during pregnancy (Days 1–12) and pseudopregnancy (Days 4–8) in the mouse. hCG was relatively ineffective in initiating ovulation during suckling-delayed pregnancy, and hCG could not induce ovulation on Days 3–6 in any animals, suggesting that follicular growth is not continuous during suckling-delayed pregnancy in the mouse. Ovulation occurred in pregnant and pseudopregnant mice following injection of gonadotropin releasing hormone (GnRH) in a gelatin delay vehicle. Injection of GnRH in saline did not initiate ovulation in pregnant or pseudopregnant mice. A large release of LH was shown to occur following injection of GnRH in gelatin, but no release occurred after the same dose of GnRH in saline. In conclusion, the experiments demonstrate the existence of mature follicles during murine pregnancy and pseudopregnancy, and the lack of inductable follicles during suckling-delayed pregnancy.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

SummaryWe have previously shown abnormalities of haemostasis suggestive of intravascular coagulation in patients with malignant hypertension, a condition associated with retinopathy and renal fibrin deposition. To determine whether such abnormalities are specific to malignant hypertension, we have measured several haemostatic and haemorheological variables in 18 patients with malignant hypertension (Group 1), 18 matched healthy controls (Group 2), and 18 patients with non-malignant hypertension (Group 3) matched for renal pathology, blood pressure and serum creatinine with Group 1. Both Groups 1 and 3 had increased mean levels of fibrinogen, factor VIIIc, beta-thrombo- globulin, plasma viscosity and blood viscosity (corrected for haematocrit); and decreased mean levels of haematocrit, antithrombin III and platelet count. Mean levels of fast antiplasmin and alpha2-macroglobulin were elevated in Group 1 but not in Group 3. We conclude that most blood abnormalities are not specific to malignant hypertension; are also present in patients with non-malignant hypertension who have similar levels of blood pressure and renal damage; and might result from renal damage as well as promoting further renal damage by enhancing fibrin deposition. However increased levels of fibrinolytic inhibitors in malignant hypertension merit further investigation in relation to removal of renal fibrin.

The purpose of the study was to conduct a comparative assessment of the course of the postoperative period after phlebectomy and thermal ablation in patients with varicose veins of the lower extremities in the system of the great saphenous vein (GSV) with class C2 of chronic venous insufficiency (CVI) — CEAP class C2. Materials and methods: 455 patients (455 limbs) with CEAP class C2. Group 1 (n = 154) received stripping + minimally invasive phlebectomy; Group 2 — endovenous laser ablation (EVLA) of GSV trunk + sclerotherapy of varicose veins; 3 group (n = 150) — radiofrequency ablation (RFA) of the GSV + sclerotherapy. All patients were united by a single tactical solution — the elimination of pathological vertical reflux in GSV. In each group, patients were with similar hemodynamic profile were selected (Group 1 = 63; Group 2 = 61; Group 3 = 61). The course of the postoperative period (from 2 days to 2 months) was compared for pain (visual analog scale — VAS), clinical symptoms of chronic venous insufficiency, degree of satisfaction (Darvall questionnaire), and duration of disability. Statistical processing was carried out using Excel programs for Windows XP, MedCalc® (version 11.4.2.0., Mariakerke, Belgium). Results: Postoperative pain is more pronounced (during day 1 for Group 1–4.0, Group 2–3.0, Group 3–2.0) and more prolonged (up to 4 days) after open surgeries (p < 0.05). The dynamics of the clinical symptoms of CVI (including varicose syndrome and use of compression therapy) could not be fully evaluated in connection with the ongoing sclerotherapy procedures for patients of Groups 2 and 3. Satisfaction of patients with aesthetic aspects was higher than expected in all groups. Reliable statistical differences proved decrease in days of disability (Group 1–14; Group 2–4; Group 3–3) and earlier return to physical activities and work in patients after thermal ablation in comparison with phlebectomy. Conclusion: The study shows that all three methods for eliminating vertical reflux in the GSV can be proposed for a large category of patients with CEAP of class C3 and C2. Medical and social rehabilitation of patients using endovascular thermal ablation technologies proceeds faster, which is beneficial both for the patients and for society.
