In this study, 32 male Wistar albino rats were divided into four groups: control, melatonin, nicotine and nicotine+melatonin.

The administration of melatonin was determined to partially alleviate histopathological changes in the liver tissue induced by nicotine, such as hepatocyte degeneration, vascular dilatation and congestion, and leukocyte infiltration. It was observed that there was a significant decrease in Bax expression levels and a significant increase in Bcl-2 expression levels in the nicotine+melatonin group when compared to the injury group. On the other hand, it was determined that melatonin administration reduced the Bax/Bcl-2 ratio, which was significantly higher in the nicotine group compared to the other groups, to a level close to the control group. Additionally, as a result of immunohistochemical evaluation, it was observed that decreased Bax expression and increased Bcl-2 expression in hepatocytes in the nicotine+melatonin group were at a level close to the control group.

Kombucha had the highest radical scavenging activity (85.61), total phenolic content (5.04 mg GAE/ mL), and total solids (0.70%), but the lowest pH (3.1) values.

Ultrasound examination and transrectal palpation or the pregnancy-associated glycoprotein (PAG) test are currently the most commonly used methods for pregnancy diagnosis. However, alternative methods to those mentioned above are constantly being sought in order to minimise stress during the examination, the cost of veterinary services and to reduce the rate of errors in pregnancy diagnosis. Non-invasive methods of pregnancy diagnosis in cows are being improved, which include the barium chloride test, sulphuric acid, seed germination test, measurement of progesterone, interferon-tau or interferon-stimulated genes (ISGs), PAG, early pregnancy factor (EPF), estrone sulphate, thermography and electrocardiography. Over the past few decades, these methods have been extensively described. Some of these tests require blood, milk or urine for the diagnosis of pregnancy, while others require prolonged contact with the animal in order to take the appropriate measurements. Despite their advantages in terms of simplicity and lower cost compared with traditional methods of pregnancy diagnosis, they are sometimes problematic because of the difficulty of collecting material for testing. They allow the determination of a pregnancy without determining its age or pathology on the part of the development of the fetus and the reproductive system. They are also generally characterised by lower accuracy, sensitivity and specificity, which can have a negative impact on reproductive management and translate into the economics of dairy production. In the context of the above information, it appears that non-invasive methods of pregnancy diagnosis need to be further improved to minimise or eliminate the disadvantages cited.</p>","PeriodicalId":94175,"journal":{"name":"Polish journal of veterinary sciences","volume":"27 4","pages":"655-665"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142904664","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}
