Bu çalışma, gebeliğin farklı dönemlerindeki fare desidua bazalis dokusunda periyodik-asit Schiff (PAS)-pozitif granüllere sahip uterus doğal katil (uNK) hücrelerinin dağılımının belirlenmesi amacıyla yapıldı. Bu amaçla, 12-14 haftalık fareler, gebe olmayan-kontrol grubu ile gebeliğin birinci, ikinci ve üçüncü haftalarının ortasına karşılık gelecek şekilde erken, orta ve geç gebelik dönemi (sırasıyla gebeliğin 3, 10. ve 17. günleri) olmak üzere 4 gruba ayrıldılar (n= 6). Plasentasyonun ilerlemesiyle birlikte metriyal bölge (MLAp; mesometrial lymphoid aggregate of pregnancy), desidua bazalis, bağlantı bölgesi ve labirint bölgesi olmak . . . üzere dört farklı bölge ayırt edildi. Desidua bazalis ve bağlantı bölgesi arasında trofoblast dev hücreleri dikkati çekti. Endometriyum dokusunda kontrol grubunda 5 adet/10.000 μm2 olarak tespit edilen PAS-pozitif uNK hücre sayısının, gebeliğin erken döneminde desidua bazalis bölgesinde arttığı dikkati çekti (26,5 adet/10.000 μm2). En yüksek uNK hücre sayısı (56 adet/10.000 μm2) gebeliğin ikinci haftasında tespit edildi. uNK hücrelerine maternal kan damarlarının içinde de rastlanırken, mesometriyal bölgedeki maternal kan damarlarının genişlediği ve tunika mediya katmanlarının belirgin bir biçimde inceldiği dikkati çekti. Gebeliğin PAS-pozitif uNK hücrelerinin sayı ve dağılımlarını etkilediği sonucuna varıldı. - Anahtar sözcükler: Fare, Gebelik, PAS, uNK = This study was carried out to determine the distribution of uterine natural killer (uNK) cells having periodic-acid Schiff (PAS) positive granules in the decidua basalis in pregnant mice. For this purpose, mice at 12-14 weeks of age were divided into four groups as non-pregnant control, and at the middle of the first, second, and the third week of the pregnancy, corresponding to early, middle, and late (3rd, 10th, and 17th days of pregnancy) gestational stages respectively (n= 6 for each group). After placentation, it was identified four different regions as metrial region (MLAp; mesometrial lymphoid aggregate of pregnancy), decidua basalis, junctional zone and labyrinth zone in mice. It was observed trophoblast giant cells between decidua basalis and junctional zone. The number of PAS-positive uNK cells was found as 5 in 10.000 μm2 in endometrium of control animals while it was determined as 26.5 number/10.000 μm2 in decidua basalis at early gestational period. The highest PAS-positive uNK cell numbers (56 number/10.000 μm2) were detected at the mid-gestational period in decidua basalis. uNK cells were also observed in the lumen of the maternal blood vessels. In mesometrial region, the dilatation of maternal blood vessels and thinning of the media layer was distinct. It was concluded that the number and the distribution of the uNK cells having periodic-acid Schiff (PAS) positive granules was affected by pregnancy. - Keywords: Mice, PAS, Pregnancy, uN More less

Bu çalışma, Merinos ırkı koyunlarda gebeliğin perifer kan lenfositlerinin alfa naftil asetat esteraz (ANAE) ve asit fosfataz (ACP-az) aktiviteleri ile perifer kan lenfosit oranları üzerindeki etkilerinin belirlenmesi amacıyla yapıldı. Hayvanlardan her grupta 20’şer adet olacak şekilde gebe olmayan-kontrol, bir aylık, iki aylık, üç aylık, dört aylık ve beş aylık gebeler olmak üzere toplam 6 dönemde perifer kanlar alındı. Histolojik incelemeler sonucunda en düşük ANAE pozitif-lenfosit oranı (%63.5) bir aylık gebe koyunlarda tespit edilirken aynı dönemde null lenfosit sayısı da en yüksek seviyede (%12.75) belirlendi. Gebeliğin son döne . . .mindeki koyunların perifer kan lenfosit (%42.9) ve ACP-az pozitif lenfosit (%43.35) oranlarında da istatistiksel olarak önemli düşüşler gözlendi. Tüm gebelik dönemlerinde perifer kan lenfosit oranlarında hormonal değişimlerin neden olduğu düşünülen dalgalanmalar olsa da en belirgin değişimler gebeliğin ilk ve son dönemlerinde gözlendi. Bu çalışmadan elde edilen bulguların maternal toleransın olası mekanizmalarının anlaşılmasına katkı sağlayabileceği sonucuna varıldı. - Anahtar sözcükler: ANAE, ACP-az, Null lenfosit, Gebelik, Koyun = This study was performed to determine the effects of pregnancy on the activities of alpha naphthyl acetate esterase (ANAE) and acid phosphatase (ACP-ase) of the peripheral blood lymphocytes in pregnant Merino sheep. Peripheral blood lymphocyte percentages were also estimated. Periferal blood samples were taken from animals in six different gestational stages as non-pregnant control, in the first, the second, the third, the fourth and the fifth month of pregnancy. Each group was contained 20 animals. The lowest ANAE (+) lymphocytes percentage (63.5%) was determined in the first month of pregnancy whereas the highest null lymphocytes proportion (12.75%) was detected in the same gestational period. There were statistically decreases in the proportions of peripheral blood lymphocyte (42.9%) and the ACP-ase (+) lymphocytes (43.35%) in the last gestational stages. Although the posibble hormonal changes may cause the fluctuation of peripheral blood lymphocyte proportions in all gestational periods, the most distinctive changes were observed at the begining and at the end of the pregnancy. It was concluded that the data was obtained from this study was useful for understanding of the possible mechanisms of maternal tolerance. - Keywords: ANAE, ACP-ase, Null lymphocyte, Pregnancy, Shee More less

The aim of this study was to evaluate a simple and rapid DNA extraction method combined with a multiplex polymerase chain reaction (mPCR) for the identification of the major mastitis pathogens (Staphylococcus aureus, Streptococcus agalactiae, Escherichia coli and Mycoplasma bovis) from milk samples. Of the 200 California Mastitis Test (CMT) positive milk samples, 45 (22.5%), 21 (10.5%) and 11 (5.5%) were detected as positive for the presence of S. aureus, S. agalactiae and E. coli by culture, respectively. In mPCR by DNA isolation method optimised here, S. aureus, S. agalactiae and E. coli were detected in 26.5% (53/200), 12% (24/20 . . .0) and 6% (12/200) of the milk samples, respectively. The abovementioned agents were observed in similar proportions when the samples were analysed by a commercial DNA isolation kit. On the other hand, M. bovis was not detected in any of the milk samples by either culture or mPCR methods. A significant difference was determined between the results of culture and mPCRs (P< 0.001). Diagnostic sensitivity and specificity of the optimised mPCR were calculated as 100% and 89.2% respectively, when culture results were considered as reference. The results suggest that the mPCR assay employed in this study could be used as an alternative routine diagnostic method for rapid, sensitive, and specific simultaneous detection of major mastitis agents in bovine milk sample More less

Canine hepatozoonosis is a tick-borne protozoan disease and widespread in Europe, Africa, Asia and America. There is not any available data about the presence of Hepatozoon infections in dogs in Kyrgyzstan. In the study we aimed that investigate the presence of Hepatozoon canis and the prevalance of Hepatozoon infections in dogs from Kyrgyzstan using polymerase chain reaction (PCR) and sequence analysis. To determine the prevelance of hepatozoonosis in dogs, a total of 170 blood samples were applied to PCR to amplify a fragment of 666 bp found in 185 SSU rRNA gene of Hepatozoon spp. The PCR results shown that Hepatozoon infection ra . . .te was 28.8% (49/170) in dogs. Eleven representative positive samples were sequenced to classification of the species. The nucleotide sequences were compared to the H. canis sequences which registered in GenBank using the basic local alignment search tool. Results of sequence analyse of 11 amplicons indicated that 8 were 100% identical and the other 3 sequences shared 99% similarity with H. canis. The sequences were deposited in Genbank with accession numbers from MG917709 to MG917719. It was the first record of H. canis in dogs in Kyrgyzstan More less

In this study, it was aimed to investigate polymorphisms in seven genes (GH, PRL, STAT5A, OPN, PIT-1, LEP and FGF2) related to reproductive traits in dairy heifers. Frequency distributions of the genotypes between fertile and repeat breeder heifers groups were investigated. Allele effects on fertility were also analyzed. Blood samples were taken from a total of 160 Holstein-Friesian heifers and they were divided into two groups according to their artificial insemination numbers (AI). The heifers becoming pregnant after the first AI were used as the fertile heifers (FH, n= 80) and the heifers with 3 or more equal AIs were accepted as . . . the repeat breeder heifers (RBH, n= 80). All the animals were genotyped by the PCR-RFLP method for seven genes and the association works were performed for 145 animals (RBH, n= 79; FH n= 66). For all loci investigated, two alleles and three genotypes were found for overall population with the exception that PRL locus had two alleles and two genotypes. The chi-square test (.2) revealed that the whole population and the two groups separately were at Hardy-Weinberg equilibrium. The genotype distributions of PIT-1 and STAT5A conspicuously differed between the FH and the RBH groups; however, these differences were not found significant. Association of GH-AB genotype was found significant on AI number for the first pregnancy. Mixed effect logistic regression model was used to investigate the allele effects on fertility. No linkage disequilibrium was detected between the investigated loci More less
