Tekelioglu, O.; Cimen, M.; Bayril, T.
This research was aimed to investigate the effect of machine milking on milk biochemical components having economic importance. In the experiment, 10 Machine Milked (MM) and 10 suckled + Hand Milked (HM) cows were used. The milk fat rates were lower for MM animals in 1st, 2nd and 4th weeks (p<0.05). Protein and total solid rates of milks were similar for both groups during study. There was found positive correlation between milk fat and total solids (r = 0.53; p<0.05), but there were no significant correlations among other milk parameters. Suckling treatment (in BM group) to increase production of milk with maximum levels of milk fat is essential for achieving the economic benefits. Producers, who utilize the MM system during lactation should expect commercial milk to be low in fat content, which may affect cheese processing characteristics.

Yildirim, Numan; Yildirim, Nuran Cikcikoglu; Yildiz, Abdunnasir
In this study, the ability to decolorize two chemically different synthetic dyes (methylene blue and crystal violet) by Pleurotus eryngii strains collected from geographically different regions of Turkey was evaluated on agar plates in static liquid cultures. For all strains, growth and decolorization halos were determined on malt extract agar plates containing 0.4 and 0.6 g/L of crystal violet (CV) or methylene blue (MB). Each P. eryngii strain showed certain decolorization capacities and was able to decolorize both MB and CV under static liquid culture conditions, but not to the same extent. The presence of the dyes in static liquid culture reduced the biomass production of all strains in comparison with control culture growing in the medium without dyes. In solid medium, a positive correlation was found between growth halo and decolorization halo.

Yildirim, Nuran Cikcikoglu; Yurekli, Muhittin
The aim of our study was to investigate the effects of methylated adrenomedullin (met-AdM) on some antioxidant enzymes, such as catalase (CAT), glutathione peroxidase (GSH-P-X) and superoxide dismutase (SOD) in rat kidney and heart tissues after cold stress treatment. Male Wistar rats were divided into 4 groups (control, met-AdM, cold stress and cold stress + met-AdM treatments). The rats were kept at room temperature, exposed to a 16/8-hours light/dark cycle. The rats were maintained at ad libitum (free) feeding habit. In met-AdM treated group, animals received intraperitoneal injection of met-AdM (2 mg/g body weight) once a day during a week. For the cold stress exposure, the rats were kept in separate cages at 10 degrees C for a week. Control group rats were kept at laboratory conditions. CAT, GSH-P-X and SOD enzyme activities were investigated in kidney and heart tissues. In kidney tissue compared to control, CAT and GSH-P-X enzyme activity was decreased but SOD was increased in met-AdM-treated group. In met-AdM+cold stress group, only the SOD enzyme activity was significantly increased but CAT and GSH-P-X decreased. SOD and GSH-P-X enzyme activities were increased by cold stress but CAT was decreased in kidney. In heart tissue, CAT and GSH-P-X activities were decreased but SOD was increased in met-AdM-treated group compared to control. All enzyme activities were decreased in met-AdM+cold stress group as well as by cold stress in heart, with regard to control. Cold stress can disrupt the balance in an oxidant/antioxidant system and cause oxidative damage to kidney and heart tissues by altering the enzymatic and non-enzymatic antioxidant status. We can suggest that met-AdM has possible roles in regulation of stress but we need further studies revealing responses of met-AdM in different tissues.

Can, Erkan; Saka, Sahin; Firat, Kuersat
The aim of this study is to determine suitable conditions for egg disinfection of gilthead sea bream (Sparus aurata), red porgy (Pagrus pagrus), and common dentex (Dentex dentex) with glutaraldehyde, hydrogen peroxide and iodine. The eggs were disinfected with 200 ppm glutaraldehyde (T= 2, 4, 8, 16 min), 300 ppm hydrogen peroxide and iodine (T= 5, 10, 15, 20 min) at four different contact times. The hatching rate was determined in triplicates for each treatment. Also, bacteria colonies were counted on tryptic soy agar (TSA) and thiosulphate citrate bile salt sucrose agar (TCBS). At the end of the experiment, bacterial load and hatching rate were assessed together. For glutaraldehyde treatment, optimal hatching rates and bacterial colonies were estimated as CT (Disinfectant concentration in mg.l(-1)* exposure time in minute) 800 for sea bream eggs, CT 1600 for red porgy eggs and CT 800-1600 for common dentex eggs. Also, for hydrogen peroxide treatments, they were determined as CT 3000 for sea bream and red porgy and CT 4500 for common dentex. Finally, in iodine treatments, these parameters were measured as CT 4500-6000 for all species' eggs. However, in our study, it is clear that the glutaraldehyde showed the optimum disinfection effect against the microorganisms because the bacteria could be eliminated completely.

Four hundred shabbout fries (Tor grypus L. 1758), with average initial weight of 0.95+/-0.02 g and total average length of 4.10+/-0.05 cm, were fed for a period of 90 days commercial feed with addition of mannanoligosaccharide (MOS) and vitamin B-12. The shabbouts were divided into four different groups and fed by different feeds (Control, Group A with MOS, Group B with vitamin B-12, Group C with the combination of MOS + vitamin B-12). The effects of feeding through MOS and vitamin B-12 in different proportions on growth in view of live weight and total length, survival rate, feed conversion, condition factor and protein efficacy were studied. The best growth in view of live weight of 4.51+/-0.16 g and length of 7.71+/-0.08 cm was maintained through vitamin B-12 in Group B. As a consequence, the growth parameters of the shabbout fries fed through commercial feeds with the addition of MOS and vitamin B-12 in different doses under empirical conditions showed affirmative effects on the survival rate, feed assessment, condition factor and protein efficacy.

Kayim, M.; Can, E.; Güner, Y.
Lordosis, which is one of the skeletal deformations, was frequently encountered in the culture of sea bass (Dicentrarchus labrax L. 1758) and it affects the biological performance and marketing image of the fish negatively. Thus it causes big economic losses. In larger natural environments, this abnormality in wild-caught individual is rare, whereas the case is the other way round in hatchery-reared sea bass. This problem can be caused by swim bladder malformations, environmental conditions, bacterial factors, water flow rate and swimming activity. However, many researchers reported that all of these factors cause these malformations in different regions of the skeletal system, commonly known as V-shaped curvatures. But in this study, it is not aimed to investigate the possible causes of the observed abnormalities. We focused on whether the abnormal individuals can be transformed into individuals with normal skeletal systems. In this study, a total number of 5636 juvenile individuals (0.09-1.93 g of live weight) were used. Lordosis rates were identified between the days 54 and 110 by randomly taking at least 30 samples from every group on a weekly basis, at triplicate. In this study, 100% of the individuals with this type of deformation were successfully transformed into individuals with the normal skeletal system in a large volume and rectangular ponds with semi-intensive rearing method.

Yildirim, Nuran Cikcikoglu; Yürekli, Muhittin; Yildirim, Numan
Purpose: The aim of this study is to investigate the compensating effects of adrenomedullin on liver tissue after cold stress treatment. Materials and Methods: Male Wistar rats were divided into four groups as control, adrenomedullin, cold stress and cold stress + adrenomedullin treated. Adrenomedullin was given by intraperitoneal injection (2 mg/g body weight) once a day for a week. For cold stress the rats were kept at 10 C for a week. Catalase, glutathione peroxidase and superoxide dismutase activities were measured in liver tissue. Results: Catalase activity was decreased significantly as compared to control in adrenomedullin treated group (p<0.05). There was no significant difference in superoxide dismutase activity (p>0.05). Glutathione peroxidase activity was increased in adrenomedullin treated group but this was statistically insignificant (p>0.05). All enzyme activities were decreased by cold stress (p<0.05). In Adrenomedullin+cold stress group, only the glutathione peroxidase activity was significantly decreased (p<0.05). Conclusion: It is concluded that cold stress induces decrease in catalase, superoxide dismutase and glutathione peroxidase activities in rat liver. Adrenomedullin treatment corrected only glutathione peroxidase activity while decreasing catalase and superoxide dismutase activities further. The discrepancy may be explained by different responses of antioxidant systems to oxidative stress. It can be concluded that oxidative factors may display unexpected effects on the regulation of glutathione peroxidase activities in the adrenonmedullin case.

Yildirim, Nuran Cikcikoglu; Yurekli, Muhittin
In this study, it was aimed to investigate the effects of chronic cold stress on adrenomedullin levels and tyrosine hydroxylase enzyme activities in some rat tissues. In this study, 12 female Sprague Dawley rats weighing 200 to 250 g were used. Rats were housed under diurnal lighting conditions (12-12 h) with free access to food and water. For this study, rats were divided into two groups, namely control group and cold stress treated group. Adrenomedullin levels were measured by high performance liquid chromatography. Tyrosine hydroxylase enzyme activities was spectrometrically measured. Tyrosine hydroxylase activity was found to be increased significantly (p<0.05) in adrenal medulla, hypothalamus and heart tissues depending on cold stress treatment. Adrenomedullin levels were determined to be decreased in the cold stress treatment group. The differences of between control and cold stress treatment groups were significant (p<0.05). The results suggested that adrenomedullin may play a possible role in adaptation to stress. Exposure to cold increases the synthesis and release of catecholamines. Tyrosine hydroxylase is the rate limiting step in the biosynthesis of catecholamines for this reason cold stress increased tyrosine hyroxylase enzyme activities. Further studies are needed to reveal correlation between adrenomedullin, tyrosine hydroxylase and cold stress.

This study was conducted in Keban dam lake Cemisgezek region during 2000-2001 fishing season. In the study, the effect of mesh size on catching efficiency was analyzed. For this reason, a total length of 800 m gillnet was used, particularly two monofilament gillnets with 50, 60, 70 and 90 mm mesh size, each being 100 m long. During the research, Cyprinus carpio and Squalius cephalus was indicated with own species names, which are caught on 22 hunting attempts. Barbus esocinus, Barbus capito pectoralis and Barbus mystaceus species regarded as Barbus sp., Capoeta trutta and Capoeta umbla species regarded as Capoeta sp. The most frequently caught species in the research were Capoeta sp. on 50 and 70 mm mesh sizes, Barbus sp. on 60 mm mesh size and Cyprinus carpi on 90 mm mesh size. The species that is least frequently fished on all gillnets was Squalius cephalus. When the catch per unit effort was analyzed taking into account all species, it was observed that with 83.1 g m(-1) catch per unit effort, 60 mm gillnet was more efficient than all other gillnets. This gillnet was followed by 79.9, 41.0 and 31.8 g m(-1) catch per unit efforts for 50, 70 and 90 mm mesh sizes, respectively. In conclusion, it has been found out that in the study region, gillnets with 50 and 60 mm mesh sizes are more effective than gillnets with 70 and 90 mm mesh sizes.
AtıfWoS1İncele - MakaleAçık Erişim2010Scopus SJRQ1The effect of adrenomedullin and cold stress on interleukin-6 levels in some rat tissues
Yildirim, N. C.; Yurekli, M.
P>Stress known to stimulate sympathetic activity, as well as the hypothalamic-pituitary-adrenal axis (HPA), produces a significant increase in adrenomedullin (AdM) levels, suggesting a regulatory or protective role for AdM in countering HPA activation that follows a variety of stressors. Stressors can modulate the secretion of proinflammatory cytokines. Interleukin (IL)-6 is a potent activator of the HPA and appears to play a pathogenic role in conditions related to stress. In the present study, we investigated the administration of AdM on IL-6 levels in cold exposed rats. Male Wistar rats were divided into four groups as control, adrenomedullin treatment, cold stress and cold stress+adrenomedullin-treated groups. In the adrenomedullin-treated group, animals received intraperitoneal (i.p.) injection of adrenomedullin (2000 ng/kg body weight) once a day for a week. For the cold stress exposure the rats were kept in separate cages at 10 degrees C for a week. Control group rats were kept in laboratory conditions. The concentration of IL-6 was determined using an enzyme-linked immunosorbent assay (ELISA) kit. When compared to control, IL-6 levels increased significantly in the cold stress- and adrenomedullin-treated groups (P < 0 center dot 05). Administration of AdM in addition to cold stress decreased IL-6 levels in lung and liver, but increased in brain and heart when compared to control (P < 0 center dot 05). The results suggest that cold stress may induce increase of rat proinflammatory cytokine IL-6 and adrenomedullin may play a regulatory or protective role for cold stress.

Yildirim, Nuran Cikcikoglu; Yurekli, Muhittin
Background: Many endogenous peptides play important regulatory roles in angiogenesis by modulating endothelial cell behavior. Adrenomedullin (AdM) is one of such factors. Angiogenesis and vascular endothelial growth factor (VEGF) are indistinguishable. Exposure to cold environment stimulates capillary angiogenesis. Objectives: Examine the effect of the bioactive peptide AdM on VEGF levels in rat liver, lung, brain, and heart tissues after cold stress treatment. Methods: Male wistar rats were divided into four groups as control, AdM treatment, cold stress and AdM+cold stress treated groups. In AdM-treated group, animals received intraperitoneal injection of AdM (2000 ng/kg body weight) once a day during a week. For the cold stress exposure, the rats were kept in separate cages at 10 degrees C for a week. Results: The administration of AdM increased VEGF levels in all tissues in cold exposed rats. Conclusion: AdM may be a major regulatory factor in angiogenesis by modulating VEGF levels that is closely associated with cold exposure-related metabolic stimulation.

The effect of ovulation stimulators (Ovopel and carp pituitary extract) on spawning of scaly carp females were investigated. Following application of Ovopel, eggs were obtained from higher percentage of females than CPE treatment (92.5 and 75.0%, respectively. In the case of Ovopel stimulator, female weights were significantly correlated with living embryo (r = 0.576, p<0.01) and hatching rates (r = 0.684, p<0.01). Also interaction between egg weights and fertilization rates (r = 0.603, p<0.01) and between hatching and living embryo rates (r = 0.679, p<0.01) were determined significant. On the other hand, egg weights were negatively correlated (r = -0.368, p<0.01) with living embryo rates. For the CPE stimulator, egg weights were significantly correlated with fertilization (r = 0.662, p<0.01), living embryo (r = 0.390, p<0.05) and hatching rates (r = 0.443, p<0.01). Also hatching were significatly correlated with fertilization (r = 0.665, p<0.01) and living embryo rates (r = 0.903, p<0.01). In addition, fertilization and living embryo rates significantly correlated (r = 0.615, p<0.01) with each other.
