This study aimed to evaluate the efficacy and the response of cows with ovarian cysts to three different treatments regardless of the cyst type. At 50 days postpartum, were considered to have an ovarian cyst when possessing a follicle with a diameter ≥ 17 mm in the absence of a corpus luteum in two ultrasonographic examinations performed at 7 days intervals. In the second examination considered (Day 0), 51 cystic Holstein cows were assigned randomly into one of 3 treatment groups.; GnRH group ( n =12) treated with 100 μg gonadorelin as a single dose, GP group ( n =12) received (100 μg gonadorelin on day 0 followed by 500 μg of cloprostenol sodium on day 7, CIDR group ( n =12) treated with intravaginal progesterone-releasing insert CIDR on the day 0: and 100 μg gonadorelin then an injection of 500 µg cloprostenol sodium IM on day 7. The CIDR was removed on day 8, and a second GnRH injection was given on day 9. From day 9, animals were observed for estrus and inseminated with proven frozen-thawed semen. Control Group ( n =15) represents cows that did not receive any treatment. Pregnancy was confirmed by ultrasound on day 28 post-insemination. Results showed that the GP group achieved the highest estrus induction rate (EIR). Thus, 44.4% of treated cows come in estrus less than 10 days and 100 % by day 20. While GnRH group showed EIR with 25% in less than 10 days and 62.5 % at the day 20. The CIDR group showed EIR (0%) in less than 10 days and 100 % at the day 20. Total conception rate (3 cycles after treatment) GP recorded (88.9%) GnRH group (87.5%) and CIDR (85.7%), while pregnancy rates (PR) was highest (66.7%) in GP protocol compared to GnRH (58.3%), and CIDR (49.9%).

Seven dogs of both sexes were assigned to this experiment with a mean weight of 20 ± 4.8 kg. Fifteen minutes after administering the acepromazine as preanesthetic medication, ketamine (3 mg/kg) was administered to 7 dogs in the group: Acepromazine -ketamine (AK). Systolic blood pressure (SBP) was measured, and echocardiography was performed immediately before application of the sedative protocol (M0), 15 minutes after the sedation (M1), and immediately after anesthesia induction (M2). The second anesthetic protocol was performed one month later with the same seven dogs; group: xylazine-ketamine (XK). Non-significant differences were observed in SBP and hemodynamic variables such as cardiac index, shortening fraction, and ejection fraction, between groups at all time points evaluated (M0, M1, and M2). The SBP was significantly reduced after anesthetic induction in dogs in the AK group. It can be concluded that; both AK and XK protocols similarly reduce the SBP in dogs subjected to anesthetic induction. All anesthetic induction protocols maintained a stable CI in all pre-medicated dogs. None of the two anesthetic protocols which were evaluated promoted significant echocardiographic changes. Furthermore, ketamine and xylazine combination hurt myocardial function. On the other hand, due to their cardiac depressant effects, acepromazine and xylazine anesthetic integration should be applied with attention in ill cases.","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132910851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its cytotoxic effect on cancer cells, it causes harm to hepatic and renal tissues, ranging from mild infiltration to necrosis and finally cytolysis, depending on the dosage and duration of treatment. It also suppresses bone marrow, resulting in leukopenia, anemia, and thrombocytopenia. This study aimed to evaluate the protective effects of concanavalin A (con-A) and IL-27 conditioned immune therapeutics on Ehrlich ascites carcinoma (EAC) tumor-bearing mice treated with CTX. To achieve this, naive splenocyte cells were activated in vitro for 3 days with the T cell mitogen concanavalin A (Con-A; 5 µg/mL) and/or IL-27 (10; ng/mL). After a single i/p injection of CTX (4 mg/mouse), they were adoptively transferred into (EAC) tumor-bearing mice. After tumor implantation, hematological analysis, liver function, and kidney function were evaluated. According to the findings, the CTX-treated group had significantly lower total leucocyte count, lymphocytes, neutrophils, hematocrit, and RBCs than the control group. Interestingly, Con-A + IL-27 normalized the total leucocytes' count, especially lymphocytes and neutrophils. When Con-A + IL-27 was compared to CTX, there was a significant increase in hematocrit and platelet count. AST, ALT, bilirubin, creatinine, and urea levels were not significantly different between normal and Con-A + IL-27, but CTX significantly increased AST compared to normal. According to the findings, adoptive transfer of Con-A + IL-27 conditioned splenocyte cells into lymphopenic hosts restored hematological and biochemical parameters and recovery from chemotherapy-induced lymphopenia.","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128818745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All used treatments, either natural or hormonal, induced significant positive effects on receptivity and fertility compared with control treatment, with the superiority of the natural methods to hormonal one. Although DLS group significantly decreased average fryer weaning weight, OP300 group increased it significantly compared with the control group. All experimental treatments achieved significantly higher weaning numbers than the control. It’s better to apply these methods on days 2 and 7 postpartum than on day 14 postpartum. It concluded that the CC and DG methods are effective in improving multiparous rabbit production. However, these treatments must only be applied to healthy herds as animal contact may serve as a source of contamination. Moreover, estrogen and progesterone can be used as good hormonal methods for improvement of rabbit production although further studies are necessary to determine how it affects the other blood hormones and whether prolonged usage of these hormones can impair ovarian function and trigger an immunological response.","PeriodicalId":166243,"journal":{"name":"Damanhour Journal of Veterinary Sciences","volume":"40 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120906819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
