Histo-anatomical studies on the accessory reproductive glands of the Anatolian souslik (Spermophilus xanthoprymnus) (Mammalia: Sciuridae)     

Cakir M  Karataş A 《Anatomia, histologia, embryologia》2004,33(3):146-150

In this study, the histo-anatomy of the accessory reproductive glands of the Anatolian souslik (Spermophilus xanthoprymnus) is investigated, using 102 males of the vouchers which were captured from central Anatolia and eastern Mediterranean regions. Averages of measurements taken from each part of the accessory reproductive glands were as follows: length of vesicular gland [right: 3.96 (+/-0.48) mm; left: 3.70 (+/-0.55) mm]; prostate gland [length: 2.55 (+/-0.38) mm; width: 2.63 (+/-0.45) mm]; length of bulbourethral gland [right: 2.32 (+/-0.33) mm; left: 2.37 (+/-0.39) mm], and the length of the pars pelvina of the urethra was 12.31 (+/-0.76) mm. Histological sections showed that vesicular gland was composed of typically branched tubulo-alveolar glands. As the fibrous connective tissue that was found among alveoles in the prostate was dense and relatively common, only few tubulo-alveolar glands occurred. The bulbourethral gland (Cowper's gland) was a tubulo-alveolar gland with a large and serrated lumen and septa between the alveoles consisted of dense fibro-muscular fibres.  相似文献   

Field evaluation of a PCR for the diagnosis of chlamydial abortion in sheep     

Güler L  Hadimli HH  Erganiş O  Ateş M  Ok U  Gündüz K 《The Veterinary record》2006,159(22):742-745

A total of 94 vaginal swab samples and 195 serum samples collected from aborted ewes in 15 flocks were examined by pcr and a complement fixation test, respectively. In addition, 172 samples of stomach contents from fetuses from different flocks submitted for the diagnosis of abortion during the four lambing periods between 2000 and 2004 were tested by pcr. Chlamydial dna was detected in seven vaginal swabs obtained from five of the 15 flocks and in six samples of fetal stomach contents. The results of pcr and flock serology for Chlamydia were positive in five of the 15 flocks and negative in eight.  相似文献   

First genetic characterization of equine adenovirus type 1 (EAdV-1) in Turkey     

Ataseven VS  Oğuzoğlu TÇ  Başaran-Karapınar Z  Bilge-Dağalp S 《Research in veterinary science》2012,92(2):324-326

Equine adenovirus type 1 (EAdV-1) is a cause of repiratory tract infection in equids. In present study for the first time in Turkey, the prevalence of EAdV-1 in nasal swab samples obtained from horses showing respiratory symptoms was investigated by polymerase chain reaction (PCR), and molecular characterization of the hexon gene detected in the Turkish (TR) strain was performed. Overall, the prevalence of EAdV-1 was found low (1.4%) as indicated by a positive PCR reaction from the nasal swab extracts tested. Phylogenetic analysis based on the partial sequences of the hexon gene of a TR-EAdV-1 strain with those of previously isolated AdVs from different mammals and an EAdV-1 M1 strain showed that the EAdV-1 strains were placed into a unique cluster. Although the TR-EAdV-1 strain was closely related to CAV-1, CAV-2 and bat adenovirus reference strains, larger-scale studies are necessary to better understand the molecular epidemiology and population structure of EAdV-1 in Turkey.  相似文献   

Effects of α-lipoic acid, vitamins E and C upon the heat stress in Japanese quails     

Halıcı M  Imik H  Koç M  Gümüş R 《Journal of animal physiology and animal nutrition》2012,96(3):408-415

Antioxidant vitamins are commonly used as colorant, preventive, sweetener, nutritive and antioxidant materials in food industry. Thus, many studies have been conducted in recent years. We have performed the present study to understand the effects of α-lipoic acid (ALA), vitamin C and E, added into rations of Japanese quails, on chronic heat stress. This study was carried out in five groups as: control, stress, ALA, vitamin E and vitamin C groups. Heat stress is applied to all groups except the control group. Superficial pectoral muscles tissues were used for biochemical determinations. During the research, it is found that heat stress exerted undesired effects such as increasing lipid peroxidation (LPO) level indicating oxidative stress in Japanese quails. In addition, superoxide dismutase (SOD) and catalase (CAT) enzyme activities and glutathione (GSH) amounts were studied to understand the behaviour of defence mechanism. While stress increased LPO ratio, it was determined that all antioxidant added into the ration decreases LPO significantly (p < 0.05). In addition, it was determined that all of antioxidants added into ration effectively restored SOD activity and LPO ratio which heat stress affected negatively. Interestingly, vitamin C did not adjust GSH ratio in contrast to vitamin E and ALA, where vitamin E and C did not perform any positive effect on heat stress decreased CAT activity. Finally, it can be thought that antioxidant vitamins relatively ameliorated these undesired affects caused by stress factors given.  相似文献   

Alpha basic crystallin expression in canine mammary tumors     

Tolga Guvenc  Mustafa Yavuz Gulbahar  Murat Yarim  Yonca Betil Kabak  Onder Karayigit  Mahmut Sozmen 《Journal of veterinary science (Suw?n-si, Korea)》2012,13(1):39-42

The aim of this study was to evaluate prognostic and/or diagnostic factors of canine mammary tumors by immunohistochemically analyzing the expression of alpha basic crystallin (αB-c). For this, formalin-fixed, paraffin-embedded blocks of 51 naturally-occurring canine mammary tumors (11 benign and 40 malignant) were used. Tissue from eight normal canine mammary glands were served as a control. Immunohistochemically, in the control mammary tissues, a few luminal epithelial cells were αB-c positive but myoepithelial cells were negative. In benign or simple type malignant tumors, αB-c expression was observed in luminal epithelial cells while the myoepithelial basal cells were negative. In benign or complex type malign tumors, positive staining was predominantly found in the cytoplasm of epithelial cells. Immunoreactivity of αB-c was also observed in neoplastic myoepithelial cells. Statistically, the number of cells immunolabeled with αB-c was found to be significantly different among tissues from normal canine mammary glands, benign lesions, and malignant tumors (p < 0.05). αB-c immunoreactivity was higher in malignant tumors than the control mammary tissues (p < 0.001). Data obtained in the current study revealed a strong association between high expression levels of αB-c and primary mammary gland tumors in canines.  相似文献   

Armillaria ostoyae associated with dying 60‐year‐old Scots pines in northern Turkey     

A. Lehtijärvi  H. T. Doğmuş ‐Lehtijärvi  A. G. Aday 《Forest Pathology》2012,42(3):267-269

We investigated an Armillaria root disease centre in a 60‐year‐old, naturally regenerated Pinus sylvestris stand located at 1250 m altitude in Sinop province in northern Turkey. Based on sequence analysis of the internal transcribed spacer region of the rDNA, the mycelial fans sampled from the infected trees were Armillaria ostoyae. Multilocus genotyping indicated that the fans belonged to a single genet, at least 0.2 ha in size. Drought as a predisposing factor is discussed. The study area received 50–70 and 25–50% of the normal precipitation in May, June and August in 2009 and in August and September in 2010, respectively. Moreover, earlier excavation work to prepare a forest road had probably disrupted the water table in the affected stand.  相似文献   

Effects of Extraction Rates of Wheat Flour on Phyllo (Yufka) Properties at Different Storage Temperatures     

Mustafa Erbas  Mustafa K. Uslu  Muammer Demir  Muharrem Certel 《Cereal Chemistry》2010,87(5):398-402

Phyllo sheets were produced with flour obtained at different extraction rates (53, 58, or 67%), and stored at 4 and 25°C. Physical, chemical, and sensory properties of fresh and stored phyllo were researched. Fresh phyllo samples from wheat flour at 53% extraction rate were thinner (0.4 mm) and had whiter color (L* = 87.6). Textural properties and overall sensory acceptability of phyllo samples significantly decreased (P ≤ 0.01) with increased extraction rates and storage times. At the end of four days, toughness and extensibility decreased from 0.88 N and 10.9 mm to 0.65 N and 6.7 mm at 4°C and to 0.45 N and 5.6 mm at 25°C. The 53% extraction rate was more suitable for producing phyllo. The shelf life of phyllo samples for preparing borek was determined four days at 4°C and two days at 25°C according to acid contents and sensory properties.  相似文献   

Effects of afforestation on microbial biomass C and respiration in eroded soils of Turkey     

Omer Kara  Emre Babur  Lokman Altun  Mustafa Seyis 《Journal of Sustainable Forestry》2013,32(6):385-396

ABSTRACT

Soil erosion is a major socioeconomic and environmental problem in Turkey. Almost 86% of the land in Turkey has suffered various degrees of soil erosion. The objective of this study was to determine whether differences in tree species affect soil characteristics and microbial activity in degraded soils. Results from this study showed that organic C (C_org) was highest in the black locust soil at 0–20 cm depth and lowest in the bare land. Microbial biomass C (C_mic) increased in the order black locust > Scotch pine > bare land at two soil depths. One-way ANOVA demonstrated that afforested soils contain significantly higher microbial biomass C than those in the bare land soils. Microbial quotient (C_mic/C_org) of soils are positively influenced by afforestation as the bare land soils exhibited lower microbial quotient than the associated Scotch pine and black locust soils. Microbial communities in black locust soils were energetically more efficient—had a lower metabolic quotient (qCO₂)—with a higher C_mic/C_org compared to those in Scotch pine soils. However, the microbial quotient in our study was still below range and cannot reach equilibrium again 15 yr after afforestation. Restoration of degraded lands could be a long-term process from microbial activity in the observed regions.  相似文献   

The Determination of Soil Boron Fractions,Their Relationships to Soil Properties and the Availability to Olive (Olea europea L.) Trees     

Serhat Gürel  Haluk Başar  Ece Keskin  Mehmet Sabri Dirim 《Communications in Soil Science and Plant Analysis》2019,50(8):1044-1062

This study was conducted to investigate the various boron fractions in olive tree grown soils. The correlations between boron fractions in leaves, fruits and soil properties were examined. For this purpose cv “Gemlik” olive (Olea europaea L.) orchards were visited. Soil samples from 0–30 cm and 30–60 cm deep, the leaf and fruit samples were collected. The greatest proportion of total soil boron is present in residual form (85–88%). It is followed by organically bound B (2.84–4.50%), specifically adsorbed on soil colloid surfaces (0.93–1.31%), oxides (manganese oxyhydroxides, amorphous Fe and Al oxides, crystalline Fe and Al oxides) bound B (7.27–8.31%). The smallest one readily soluble (extracting plant available) boron values were composed of only 0.40–0.50% of total boron ranging. To determine readily soluble boron five different extraction solutions were in the order Hot water ? 0.01 M CaCl₂ ? 1 M NH₄OAc ? 0.1 M KCl ? 0.005 M DTPA. Fruit boron concentration and soil boron fractions showed close correlations than leaf boron concentration.  相似文献
