Immunohistochemical study on roe deer haemal nodes

Background: The aim of this study was to investigate the immunohistochemical characteristics of the haemal nodes located in the abdominal and thoracic cavities in roe deer (Capreolus capreolus). Materials and methods: In this study, 2 adult male and 2 adult female roe deers in addition to 2 roe deer foetuses at the late foetal stages were used. The avidin-biotin-peroxidase technique was applied to anti-CD3, anti-CD79acy, anti­-macrophage, anti-S100 primary antibodies. Results: Positive results were gained for all the antibodies used. Many CD3 positive T-lymphocytes were seen in the lymphoid tissue areas of the foetal haemal nodes, in the germinal centre of the lymph follicles of the adult haemal nodes and in their lymphatic cords. CD79acy positive cells were less in number while S-100 protein was positive in both lymph follicles and in sinuses of the adult haemal nodes. In foetal haemal nodes, cells positive for S-100 protein were more prevalent in the sinuses. For the MAC387 primary antibody, there were positive macrophages seen in the capsule and trabeculae of the haemal nodes, located denser in males. Macrophage cells in the lymphoid structures and granulocytes in the sinuses of the haemal nodes of both adults and foetuses were positive for MAC387. Conclusions: This study is the first one to define the detailed structural features immunohistochemically in the haemal nodes of the roe deer. Even it’s concluded that the results were similar with the other ruminants, it’s also pointed out that there are certain differences among the foetal, adult male and female haemal nodes of the roe deer.

Anatomical and histological analysis of the salpinx and ovary in Anatolian wild goat (Capra aegagrus aegagrus)

Background: This study determined the anatomical and histological structure of the salpinx and ovary of the Anatolian wild goat (C. aegagrus aegagrus). Materials and methods: The salpinges and ovaries from four wild goats of similar ages were used. These goats were brought to the Kafkas University Wildlife Rescue and Rehabilitation Centre (Kars, Turkey) for various reasons such as traffic accidents or firearm injury, but either could not be saved or were euthanased. Results: The mean length of the ovary was 13.22 ± 1.27 mm, width was 8.46 ± 0.88 mm, thickness was 5.67 ± 0.79 mm, and weight was 0.59 ± 0.17 g. The mean length of the salpinx was 58.11 ± 14.02 mm, width was 0.80 ± 0.22 mm, thickness was 0.41 ± 0.01 mm, and weight was 0.30 ± 0.08 g. The salpinx consisted of three different regions (infundibulum, ampulla, and isthmus). These regions consisted of tunica mucosa, tunica muscularis, and tunica serosa. Prismatic epithelial cells were observed in the lamina epithelialis of the tunica mucosa in every region. Conclusions: The data resulting from this study regarding anatomical and histological structures of the salpinx and ovary in the genital system organs of Anatolian wild goat will support other studies seeking to improve reproductive efficiency and eliminate the danger of extinction of this species

The morphological investigations on the heart and some vessels of bovine foetus between the 15th and 25th weeks of gestation

Background: The aim of this study was to define the morphological and morphometric development of the foetus heart obtained from the domestic cattle in the gestation period of 15–25 weeks. Materials and methods: For this purpose, a total of 30 hearts belonging to cattle foetuses (15 males, 15 females) were used. The ages of foetuses were calculated according to the forehead-to-tail length and examined in three different groups. After dissection; biometric, macroanatomic, morphometric and histological findings were obtained from the foetal hearts according to the groups. In addition, mean values of the morphometric findings were determined. Results: As a result of the study, it was found that with the advancing age the convexity of margo ventricularis dexter increased and margo ventricularis sinister transformed from a convex-concave shape to a flat shape. The heart-to-body weight ratio was determined as 0.08% for Group II female foetuses and 0.09% for all other groups. The heart heights for Groups I, II, and III females were identified as 26.21, 41.00, and 46.27 mm, respectively, and for the males 26.45, 34.89, and 47.15 mm, respectively. In the statistical analysis, it was determined that all the morphometric values measured from the heart correlated significantly with the forehead-to-tail length. Conclusions: The data obtained as a result of the study is thought to help understand the morphological and morphometrical development of the heart, pioneer the attempts to create a foetal cattle heart model, and thus help in the diagnosis of the foetal heart pathologies.acieleck

Immunohistochemical examination of effects of kefir, koumiss and commercial probiotic capsules on platelet derived growth factor-c and platelet derived growth factor receptor-alpha expression in mouse liver and kidney

We investigated using immunohistochemistry the effects of kefir, koumiss and commercial probiotic capsules on the expression of platelet derived growth factor-c (PDGF-C) and platelet derived growth factor receptor-alpha (PDGFR-alpha) in mouse liver and kidney. Mice were assigned to four groups: group 1 was given commercial probiotic capsules, group 2 was given kefir, group 3 was given koumiss and group 4 was untreated. After oral administration for 15 days, body weights were recorded and liver and kidney tissue samples were obtained. Hematoxylin and eosin staining was used to examine histology. PDGF-C and PDGFR-alpha in liver and kidney were localized using the streptavidin-biotin peroxidase complex method (ABC). We found that the weights of the mice in the kefir, koumiss and commercial probiotic capsules groups increased compared to the control group. No differences in liver and kidney histology were observed in any of the experimental groups. Kefir, koumiss and the commercial probiotic preparation increased PDGF-C and PDGFR-alpha expression.Commission for the Scientific Research Projects of Kafkas UniversityKafkas University [2012-VF-5]This Project was supported by the Commission for the Scientific Research Projects of Kafkas University, project number 2012-VF-5

Which Definition Should be used to Determine Colchicine Resistance Among Patients with Familial Mediterranean Fever?

Objectives: Colchicine is the main therapy for familial Mediterranean fever (FMF); however, 5-10% of patients are colchicine-resistant. There is no standard and validated definition for colchicine resistance. We aimed to compare the existing definitions for colchicine resistance in both adult and paediatric FMF patients to find out the best definition to determine colchicine-resistant patients. Methods: 385 FMF patients were evaluated and patients receiving anti-interleukin-1 treatment were included. The anti-IL-1 therapy had been initiated by the experts in the past based on their experience. Eleven different definitions (found out after PubMed search for colchicine resistance in FMF) were applied to all patients. Results were re-analysed after excluding the patients who had no clinical attacks but persistently high acute phase reactants (APRs) and/or amyloidosis. Results: Sixty patients (40 adults/20 children) who had been using anti-IL-1 therapy were included into this study as colchicine-resistant patients. The highest percentage of patients fulfilled definition 5 (93.3%). Definition 9 had the poorest performance (26%). Significantly, a higher percentage of adult patients met definitions 4 and 6 than paediatric patients (87.5% vs. 50%, p=0.002; 75% vs. 40%, p=0.008, respectively). After excluding patients without clinical attacks, the highest percentage of patients fulfilled definition 2 (94.4%). We combined the attack frequency (>1 typical episode/3 months) in definition 2 and presence of amyloidosis/APR increase (increase in ≥2/3 APRs) in definition 5 to create a new definition which was met by 59 (98.3%) colchicine-resistant FMF patients. Conclusions: Definition of colchicine resistance is still controversial. Definitions with both clinical and laboratory criteria were met by a higher percentage of resistant patients than those without laboratory criteria. However, the proper definitions for the attack-free period and persistence of APRs are still lacking.PubMe

A snapshot of geriatric infections in Turkey: ratio of geriatric inpatients in hospitals and evaluation of their infectious diseases: A multicenter point prevalence study

Introduction: The human population is aging at an astonishing rate. The aim of this study is to capture a situation snapshot revealing the proportion of individuals aged 65 years and over among inpatients in healthcare institutions in Turkey and the prevalence and type of infections in this patient group in order to draw a road map. Materials and Methods: Hospitalized patients over 65 years at any of the 62 hospitals in 29 cities across Turkey on February 9, 2017 were included in the study. Web-based SurveyMonkey was used for data recording and evaluation system. Results: Of 17,351 patients 5871 (33.8%) were ≥65 years old. The mean age was 75.1 ± 7.2 years; 3075 (52.4%) patients were male. Infection was reason for admission for 1556 (26.5%) patients. Pneumonia was the most common infection. The median length of hospital stay was 5 days (IQR: 2–11 days). The Antibiotic therapy was initiated for 2917 (49.7%) patients at the time of admission, and 23% of the antibiotics prescribed were inappropriate. Healthcare-associated infections developed in 1059 (18%) patients. Urinary catheters were placed in 2388 (40.7%) patients with 7.5% invalid indication. Conclusion: This study used real data to reveal the proportion of elderly patients in hospital admissions. The interventions done, infections developed during hospitalization, length of hospital stay, and excessive drug load emphasize the significant impact on health costs and illustrate the importance of preventive medicine in this group of patients. © 2020 The Author
