In this study, it was aimed to evaluate the levels of interleukins such as IL-1β, IL-6, IL-10 and IL-12β in sheep with Jaagsiekte by immunohistochemical methods. In this way, it will be revealed whether interleukins are effective in the progression of Jaagsiekte and how useful they are in the diagnosis of the disease. The material of the current study consisted of lung tissues of 26 sheep (Control, n=6 and Jaagsiekte, n=20) brought to the Department of Pathology for routine histopathological diagnosis. Tissue samples taken were fixed in 10% buffered formaldehyde solution. 5 µm-thick sections were taken from the paraffin blocks prepared after routine tissue follow-up procedures. Hematoxylin & Eosin staining was applied to the sections in order to detect histopathological changes. Sections were examined and photographed under a light microscope. The routine streptavidin–biotin peroxidase complex method was used.In sheep with Jaagsiekte, tumoral foci with large and small acinar or papillary growths were observed in the alveolar and bronchiole lumens. The control group was negative for IL-1β, IL-6, IL-10 and IL-12β immunoreactivity. IL 1β-6-10 and 12β levels were dramatically increased in the Jaagsiekte group compared to the control group.It was determined that interleukins were produced from tumoral cells and tumor microenvironment elements, and these interleukins showed pro-inflammatory effects, except for IL-10.

This study aimed to monitor oxidative stress parameters including total antioxidant status (TAS) and total oxidant status (TOS), and tumor necrosis factor-alpha (TNF-α) level during the healing process in hair goats with metritis. This study was carried out on a total of 25 hair goats with metritis (n=10; Group 1) and healthy (n=15; Group 2). The beginning of the study was accepted as day 0. In both Group 1 and Group 2, blood samples were collected on days 0 (first measurement day), 14 (second measurement day) and 28 (third measurement day) of the study for TAS, TOS and TNF-α analyzes. In addition, oxidative stress index (OSI) was calculated using TAS and TOS values.It was found that TAS level decreased in Group 1 compared to Group 2 at the first measurement day (p<0.05). However, TOS, OSI and TNF-α levels increased in Group 1 compared to Group 2 (p<0.01). At the second measurement day, TOS and OSI values were higher in Group 1 than Group 2 (p<0.05).In conclusion, the antioxidant system weakened, oxidative stress and TNF-α levels increased in animals with metritis compared to healthy animals. However, at the third measurement time, all parameters became similar between groups.

Kara, Hulya | Ozudogru, Zekeriya
Objective: This study aimed to reveal the coronary veins and the branches that join it to provide venous drainage of the heart in Southern Karaman sheep. Material-Method: Eight Southern Karaman sheep’s heart tissues were used in the study. Latex injection techniques were used to determine the coronary veins and the branches that join it for providing venous drainage of the heart.Result: In the study, vena cordis magna, vena cordis media, and vv. cordis dextra was observed as venous drainage providing vessels. The vena cordis magna began in the lower third of the sulcus interventricularis paraconalis, called vena interventricularis paraconalis. This vein reached the sulcus coronarius and continued as vena circumflexus sinister. Vena cordis media was named as vena interventricularis subsinosus in sulcus interventricularis subsinosus. The vv. cordis dextra was responsible for the venous drainage of the facies atrialis of the heart.Conclusion: In the evaluation of the study findings, it was determined that the coronary veins and the branches joined it of Southern Karaman sheep were mainly similar to other sheep breeds in the literature. Still, there were some anatomical differences, for example; vena distalis ventriculi sinistri was opening into vena circumflexus sinister, vena apicis cordis was absent, vena semicircumflexa dextri was present.

To investigate the possible effect of N-acetylcysteine (NAC) treatment on rat diabetes-induced liver damage and immune reactivity of asprosin hormone in the liver. Twenty-eight Wistar albino male rats were used in the study. They were separated into 4 groups as Control (n=7), Diabetes (n=7), Diabetes+NAC (n=7), and NAC (n=7). The rats in all groups were dissected after the treatment, and liver tissues were taken for pathological examination. Tissue sections were stained with immunohistochemistry for detecting asprosin immunoreactivity, hematoxylin-eosin and picrosirius red staining were performed to determine the changes in the tissues.In the microscopical examination of hematoxylin-eosin-stained sections normal histological hepatic tissues were seen in the Control and NAC groups. Pathological examination of liver tissue from diabetic rats showed marked dissociation, fibrosis, degeneration, inflammation, necrosis, Kupffer cells activation, bile duct proliferation, and congestion. A significant decrease in these lesions was observed in the DM+NAC group. Immunohistochemical studies showed that asprosin immunoreactivity was increased in the DM group in a significant manner. Asprosin expression was observed to be significantly reduced in the DM+NAC group in comparison to the DM group.Our findings show that NAC administration reduces liver damage in diabetic rats and can be used to reduce/eliminate the negative effects of diabetes in rat liver tissue..

This study aimed to investigate the effects of Chia (Salvia hispanica L.) oil and Dandelion (Taraxacum Officinale) extract on Tumor Necrosis Factor-α (TNF-α) and Interleukin 6 (IL-6) release in liver tissue of diabetic rats. Experimental groups were created as control, sham, chia, dandelion, diabetes (DM), diabetes+chia (DC), and diabetes+dandelion (DD). Body weight and blood glucose measurements were taken on the 1st, 3rd, and 17th days of the study and evaluated statistically. A one-way ANOVA test was performed to determine the differences between the groups. The Duncan test was used to compare significant differences between groups. At the end of the study, Masson's trichrome staining and Hematoxylin-Eosin staining were employed for histological examinations of liver tissues, and the distribution of TNF-α and IL-6 was examined by applying the Streptavidin-biotin peroxidase method.It was determined that body weight and blood glucose measurements were significantly decrease for the DC group compared to other groups. Immunoreactivity of TNF-α and IL-6 was found to decrease in DC and DD groups at close to the control levels.Based on our results, it was thought that the use of chia and dandelion in diabetes may contribute to the alleviation of disease-related complications by having a positive effect on proinflammatory cytokine levels.

This study was to examine the opinions of first-year veterinary faculty students about the use of plastinated anatomic prosections in addition to wet cadavers in anatomy practical lessons. The students were shown plastinated organs and organs fixed in formaldehyde. Then a questionnaire comprising 7 questions was administered to the 100 student participants. The questionnaire responses were analyzed statistically using SPSS vn. 22.0 Frequencies software.In response to question 1, 58.4% of the students thought that there was no anatomic difference between the plastinated organs and the organs fixed in formaldehyde. In contrast to the strong smell of formaldehyde, 88% of the students stated that the plastinates were odourless. The use of plastinated organs was thought to improve the quality of education by 89.1% of the students, compared to the negative aspects of formaldehyde. It was stated by 84.2% of the students that plastinated organs should be included in anatomy lessons due to the thoughts of the majority of the students that plastinated tissues could make a greater contribution to anatomy lessons. In response to the final question, 92.1% of the students stated that they felt no abhorrence of the plastinated organs.Plastination may be especially useful for educational institutions without access, space, or the financial resources for dissection, and can emphasize unique or pathological samples. The results of this study demonstrated that plastinated samples were perceived as a useful addition to traditional resources in the teaching of anatomy.

2022
Eli̇foglu, Taha Burak | Biskin, Merve | Macun, Hasan Ceyhun | Kul, Oguz
Squamous cell carcinoma (SCC) is a malignant epithelial tumor of skin. All species of animals are vulnerable to SCC and, sheep are very rarely developing this type of skin carcinoma. The purpose of this report was to describe unusual mammary lobe localization of SCC showing a great resemblance to the mammary tumor according to its gross and clinical examinations. The sheep was brought to department of obstetrics and gynecology and, tumoral tissue was totally extirpated with a suspicion of mammary tumor. The diagnosis made as differentiated squamous cell carcinoma originated from the skin surface and invading through the dermis and subcutis but mammary gland parenchyma was remained intact. There are only few reports of SCC cases belonging to the skin of the mammary area in sheep. Therefore, it is thought that this case will make a scientific contribution with its originality and rarity.

2022
Aissanou, Sofiane | Besseboua, Omar | Ayad, Abdelhanine
In contrary to most domestic livestock species, the common donkey (Equus asinus) is widely known as an animal with marked seasonality in reproductive activity. The annual cycle of daily photoperiod has been identified as the determining factor in sexual activity. A synthesis of the particularities of donkey reproduction is important and constitutes a basis of scientific reflection for managing asine livestock farms and establishing a well conservation plan for the different breeds around the world. It is necessary to have a perfect knowledge of the seasonal physiological changes in order to optimize the reproductive characteristics of donkeys. The objective of this paper is to review the current state of knowledge on the reproduction seasonality of common donkeys. We start with a remainder of some anatomical of the genital apparatus and sexual behavior aspects. Moreover, the investigations undertaken by many authors reveal the influence of the season on testicular biometry, histology, seminal and hormonal parameters in male donkeys populations. In conclusion, despite scientific controversy on the reproductive seasonal character in donkeys, it could likely be influenced by several factors mainly the photoperiod.

It was aimed to investigate the effects of ketamine combination administered with xylazine used for general anesthesia in dogs on arterial blood pressure, heart rate, and body temperature. Materials and Methods: In the study, a total of 20 dogs, 14 females and 6 males, from various breeds and ages 1 to 5, which undergone elective ovariohysterectomy or castration according to body weights. 1 mg/kg xylazine (xylazine hydrochloride, 23.3mg/ml, Xylazinbio 2% Bioveta®, Czechia) and 10 mg/kg ketamine (ketamine hydrochloride, 100 mg/ml, Ketasol 10% Richter® Pharma Ag, Austria) combination within a single injection with 21G needle were applied intramuscularly. The food and water access were ceased 12 hours before drug administration. Systolic and diastolic blood pressures, pulse measurements, and body temperatures were measured 3 times before and 5 times during anesthesia (at the 15th, 30th, 45th, 60th and 120th minutes of anesthesia) by using the AM6100 veterinary bedside monitor. Muff was placed to cover 1/3 of the proximal leg and for the artery to be recognizable by the microprocessor. Pulse rates were measured with electrodes connected to the device. Body temperature was measured by a rectal thermometer which was a part of the device. Measurements were taken before anesthesia was considered as control measurements.In systolic blood pressure, the recordings at 0, 15th, 30th mins have been found as statistically significant in relation to 45th, 60th, and 120th (p<0.05). In diastolic blood pressure, there were no significant differences recorded. The change between the preintervention and post-application has been found significant (p<0.001). Body temperature has shown a meaningful change in comparison to the starting point after the readings (p<0.001).Eventually, decreases in blood pressure, heartbeat, and body temperature were observed for the dogs that have been anesthetized with the combination of xylazine-ketamine.
