Ten male beagle dogs were used, divided into two groups with five repetitions per group. The control (CO) animals received a diet with 0.5 mL/day of placebo for 30 consecutive days in a preventive manner, and we later added ethoxyquin at 0.4 mg/day. The treated group (TRA) received a ration with 0.5 mL/day of homeopathic for 30 consecutive days as a preventive, and we later added ethoxyquin at 0.4 mg/day. Blood samples were collected on days 1, 30, and 40 to analyze antioxidant and oxidant status. In an ethogram, the presence of a crusted lesion, alopecic lesion, or hair loss were evaluated at three timepoints: pre-challenge, 5, and 10 days post-challenge. No lesions were observed in the pre-challenge period. Dogs fed the homeopathic on day 5 after challenge presented 40% less crusted lesion and 60% less hair loss than the control. Nitric oxide (NOx) and reactive oxygen species (ROS) levels increased over time in both groups (P < 0.001). On day 40 of the experiment, lower levels of NOx (P < 0.001) and ROS (P < 0.025) were observed in the TRA group than in the CO group. In contrast, glutathione S-transferase activity increased over time in both groups (P < 0.001); however, this increase on day 40 was more significant in the dogs in the treated group than in the control (P < 0.010). We conclude that the preventive addition of homeopathic reduced the incidence of skin lesions and prevented oxidative stress caused by canine atopic dermatitis.","PeriodicalId":8351,"journal":{"name":"Archives of Veterinary Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43486799","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}

The aim of this study was to identify extrinsic (year, season), intrinsic (age and breed) and AI procedure related (number of AIs, synchronization protocols, semen preservation method) factors that influence fertility after laparoscopic AI in sheep. Data from 159 laparoscopic AI procedures were categorized according to year (from 2013 to 2017), season (Winter, Spring, Summer and Autumn), breed (Dorper, White Dorper, Texel, Cross-breed), age in months (≤12, 13-24, 25-36, 37-48, ≥49), estrus synchronization protocol (short-term or long-term), cumulative number of AIs (1 to 4) and semen preservation method (frozen or fresh). Frequency analysis using chi-square test was used. Year, age, number of AIs and synchronization protocols did not influence fertility after laparoscopic AI in sheep. Fertility was higher (P<0.05) in sheep inseminated in spring (64.28%) and summer (54.16%) when compared to winter (36.92%) and autumn (32.14%). Dorper breed fertility (58.02%) was higher (P<0.05) than White dorper (25%) and Cross-breed (30.23%). There was a lower (P<0.05) pregnancy rate in sheep inseminated with frozen semen (38.27%) than sheep inseminated with fresh semen (53.84%). In conclusion, season, breed and semen preservation method can influence fertility in sheep after laparoscopic AI.","PeriodicalId":8351,"journal":{"name":"Archives of Veterinary Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45019180","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}

Each liter of saline (NaCl 0.9%) was ozonated at 50 µg of ozone per mL for 7 min using a medical ozone generator. Then, uterine lavage was performed during estrus or 4h post-breeding and each liter of saline remained inside the uterus for 10 min before being recovered. In experiment 1, two cycles of six mares were used in a crossover design. Lavage was performed with ozonated (Treated) or non-ozonated (Control) saline 4h after the infusion of dead sperm, and cytology samples and biopsies were collected 6 and 24h later. Experiment 2, endometrial biopsies were collected before lavage (T0) and at 15 (T15), 30 (T30), and 60 (T60) days post-treatment with ozonated (n=11) or non-ozonated (n=3) saline. In experiment 3 (n=10), the pregnancy outcome was evaluated subsequent to lavage with ozonated saline 4h after insemination. In Experiment 1, there were no difference at 6h post-breeding in PMNs count on endometrial cytology between treatment and control groups (P>0.05). However, PMNs tended (P=0.09) to be superior in the experimental treatment compared to the control at 24h post-breeding. In addition, the number of PMNs tended to be lower in the control cycle at 6 h (P=0.06) and 24 h (P=0.08) in endometrial biopsies. In Experiment 2, the endometrial architecture, the numbers of lymphocytes and PMN were not affected by the treatment (P>0.05). In Experiment 3, nine out of 10 mares were confirmed to be pregnant after treatment, and there was not pregnancy loss up to 60 days. In conclusion, uterine lavage with ozonante saline solution may cause a mild endometrial inflammation, however, doesn’t harm the endometrium or impact pregnancy outcomes in healthy mares.  ","PeriodicalId":8351,"journal":{"name":"Archives of Veterinary Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48659798","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}

The incorporation of modern radiotherapy techniques, along with studies that contribute to the development of radiotherapy protocols in veterinary medicine, may contribute to improve the quality of treatments and survival of animals affected by cancer. A TPS applied in a human radiotherapy clinic was used and the radiometric, clinical and anatomical parameters were adequate for the feasibility of use in veterinary radiotherapy. Tomographic images of the pelvic region of wild animals assisted by the School of Veterinary Medicine and Animal Science (FMVZ/UNESP) were used to perform them. Protocols for the implementation of computational planning in veterinary medicine were verified by analyzing the homogeneity of the radiation dose distribution in the planned treatment volume (PTV) and ensuring the protection of the organs surrounding the PTV.
