Researchers have sought to extend semen preservation effectiveness for more than 24 hours. Due to the particular physiological characteristics of small ruminant spermatozoa, the cooling procedure decreases its reproductive ability. Objectives: This study aimed to determine the effect of adding L-carnitine (LC) to the cooling extender on the quality of the ram’s sperm following cooling preservation at 4°C. Methods: The collected sperm samples were diluted and divided into 4 groups with varying doses of LC supplementation (0, 1, 5, and 10 mM). The samples were kept at 4°C for up to 48 hours. At 0, 24, and 48 hours of cooling, the sperms’ total motility, progressive motility, viability, lipid peroxidation, membrane integrity, and mitochondrial activity were assessed. Results: The results showed that different treatments did not affect the quality of semen samples at time 0 of cooling storage (P>0.05). Cooling medium supplemented with 5 mM LC demonstrated improved total motility, progressive motility, viability, membrane integrity, and mitochondrial activity compared to the other groups after 24 and 48 hours of cooling (P≤0.05). Furthermore, after 24 and 48 hours of storage, 5 mM LC produced less lipid peroxidation (P≤0.05) than the other treatments. Conclusion: In conclusion, reinforcing ram’s cooling storage medium with 5 mM LC protects ram semen samples against cold-induced structural and functional impairment throughout 24- and 48-h storage.","PeriodicalId":14566,"journal":{"name":"Iranian Journal of Veterinary Medicine","volume":" 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139392400","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}

Objectives: This study aimed to evaluate the diagnostic efficacy of ultrasonography in identifying the causes of ascites in hybrid dog breeds. Methods: The current retrospective cross-sectional study involved 21 dogs of hybrid breeds (12 males and 9 females) with an Mean±SD age of 6.70±0.49 years and a Mean±SD weight of 24.37±3.65 kg. In a radiology ward, a radiologist examined the dogs by conducting an abdominal cavity ultrasound to diagnose and report the cause of ascites. Notably, the radiologist knew nothing about the history, clinical symptoms, and laboratory findings regarding the dogs. After the definitive cause of ascites was determined, the result was compared with the ultrasonographic diagnosis, calculating its sensitivity, specificity, and accuracy. Results: Liver diseases, renal conditions, and malignancies were identified as the most common causes of ascites. Based on the results, ultrasonographic diagnosis revealed the following specifications: 97.8% specificity, 91.1% sensitivity, 94.4% accuracy, 97.8% positive predictive value, and 91.1% negative predictive value. Conclusion: In general, the research results indicate that ultrasonography can serve as a primary tool for diagnosing the early stages of ascites. In a few cases where diagnosis of the underlying cause proves challenging, this method helps reach a subsequent diagnosis, except in cases involving liver and renal complications. Also, ultrasonographic diagnosis gets around invasive techniques such as sampling and laparoscopy, reducing the hospitalization period, hospital costs, and patient stress and also facilitating the medical process.","PeriodicalId":14566,"journal":{"name":"Iranian Journal of Veterinary Medicine","volume":" 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139393604","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}

Xerostomia is among the adverse effects that can dictate treatment cessation or the use of some agents that decrease its cytotoxic effects. Objectives: This study aims to identify the histological effects of cytarabine on the rabbits’ parotid gland and to assess the ameliorating α–tocopherol impact on these effects. Methods: The study rabbits were separated into 4 groups. Group A (control) was given 1 mL of intraperitoneal (IP) injection of normal saline/day for 10 days. Group B received α-tocopherol (800 IU) by gavage for 10 days. Group C received cytarabine (60 mg/kg/d) IP for 10 days. Group D received α-tocopherol (800 IU) by gavage before injection of cytarabine (60 mg/kg) at the same time for 10 days. The rabbits were euthanized, and tissue preparation for analyzing microscopically and immunohistochemically for B-cell lymphoma 2 (Bcl-2) and tumor-necrosis-factor (TNF)-α was achieved. Results: Microscopically, group B’s parotid salivary gland sections revealed increased thickness of connective tissue of the trabeculae, degeneration, and necrosis of serous acini cells with aggregation of inflammatory cells. In contrast to the histopathological alteration of the glands in group C, which is characterized by intact serous acini, intercalated duct, and normal thickness of trabeculae, in the cytarabine group, TNF-α immunohistochemical expression was of grade 3 and in the cytarabine with α-tocopherol group was of grade 1. The Bcl-2 immunohistochemical expression in the cytarabine group was of grade 0, and in the cytarabine with α-tocopherol group was of grade 1.

Objectives: This study aimed to investigate the clinical and pathological changes in arthritic bovine calves. Methods: The study was conducted on 12 calves with swollen knees or carpal joints. All calves were evaluated through clinical, radiographic, and ultrasonographic examination. Peripheral blood was aspirated from each to assess hematobiochemical changes. Synovial fluid and infected swab samples were subjected to bacteriological analysis, and a synovial biopsy was taken for histological examination. Results: Ultrasound revealed inflammatory effusions with various echogenicity in the afflicted joint capsule, while radiography showed remarkable swelling of joints and surrounding structures and the development of new bone. Regarding hematological variables, the value of total erythrocyte count, total leukocyte count, and erythrocyte sedimentation rate significantly (P<0.05) increased in septic arthritic calves compared to healthy calves. In the arthritis group, the serum concentration of alanine transaminase, alkaline phosphatase, and aspartate aminotransferase was considerably (P<0.05) higher than in healthy calves. The total protein and urea values were significantly (P<0.05) decreased in calves with infected arthritis. From the synovial fluid and purulent discharge of the joints, Staphylococcus aureus and Escherichia coli were isolated. Histopathology of synovial tissue revealed chronic suppurative inflammation with intense hyperplasia of joint synovium.

Objectives: This study aimed to evaluate the association between the detection of Mycoplasma sp., bovine herpesvirus 1 (BHV-1), and bovine viral diarrhea virus (BVDV) in the conjunctival sac of the eye and IBK. Methods: Polymerase chain reaction (PCR) was employed to detect Mycoplasma sp., BHV-1, and BVDV in samples collected from IBK-affected and healthy eyes. Results: Based on the PCR results, Mycoplasma sp. was detected in 63.6% and 47.2% of IBK-affected and healthy eyes, respectively. BHV-1 was detected in 59.1% and 36.1% of affected and healthy eyes, respectively. BVDV was detected in 65.9% and 58.3% of affected and healthy eyes, respectively. BHV-1 was the only agent significantly (P<0.05) associated with IBK lesions (isolated from 59.1% of affected vs 36.1% of healthy eyes).

Researchers in morphology and immunology have long sought to delve into the structure and function of the dromedary’s immune system to gain a deeper understanding of its mechanisms and potential applications in human and animal health. Objectives: This study aims to elucidate the histological architecture and cellular composition of the lymph nodes in the indigenous dromedary breed of the El Oued region in Algeria and to compare the results with those of prior investigations of lymph node structures in other mammalian species. Methods: Hematoxylin, eosin stain, and Masson’s trichrome stain techniques were used for histological analysis. In contrast, methylene blue, eosin, and May-Grünwald Giemsa staining techniques were used for cytological analysis. The study data were collected and analyzed using qualitative and quantitative methods to identify the histological and cellular features of the lymph nodes. Results: Our study revealed that the lymphatic follicles in the dromedary’s lymph nodes have a higher concentration of lymphocytes within the follicles’ germinal center than other species. The lymph nodes were observed to be divided into conglomerates. The cytological study showed that the major cellular population consisted of lymphocytes, followed by macrophages and reticulocytes according to the localization and the functional zone.
