Öğe The Changes Associated with Fasting and Acute Heat Stress on Body Temperature Blood Acid-Base Balance and Some Parameters of Japanese Quail(INDIAN VETERINARY ASSOC, 1998) Durgun, Z; Keskin, E[Abstract not Available]Öğe Effect of garlic oil on erythrocyte membrane phospholipid fractions in hypercholesterolaemic dogs(LIPPINCOTT WILLIAMS & WILKINS, 1997) Keskin, E; Durgun, Z; Kocabatmaz, M; Tras, B; Eryavuz, A; Donmez, NWe studied the effects of a cholesterol diet alone and of a cholesterol diet plus garlic oil on erythrocyte membrane phospholipid fractions in 10 adult mongrel dogs. The animals were fed the control diet plus 0.5% cholesterol for 6 weeks and the control diet containing 5% cholesterol plus garlic oil at 20 mg kg(-1) body weight daily for the last 3 weeks of the experiment. Feeding with the cholesterol-rich diet resulted in significant (p < 0.05) increases in erythrocyte membrane lipids. The administration of garlic oil not only prevented the increases but also reduced the levels of phospholipid and cholesterol, though not significantly. Although phospholipid (PL) fractions showed fluctuations with the cholesterol feeding and garlic oil administration, there was no significant difference between the sampling times. In conclusion, further studies are necessary on the effect of garlic on the membrane PL fractions because of the importance of PL in all aspects of membrane physiology from anion transport to regulation of cell structure.Öğe Effect of garlic oil on plasma, erythrocyte and erythrocyte membrane total lipids, cholesterol and phospholipid levels of hypercholesterolaemic dogs(LIPPINCOTT WILLIAMS & WILKINS, 1997) Kocabatmaz, M; Keskin, E; Durgun, Z; Eryavuz, A30 Adult mongrel dogs were assigned randomly to three groups with 10 animals each. Group 1 served as normal controls and were fed a standard control diet for 9 weeks. Group 2 animals received the control diet plus 0.5% cholesterol powder for 9 weeks and Group 3 animals were fed the control diet plus 0.5% cholesterol for 6 weeks and received the control diet containing 5% cholesterol plus garlic oil at the rate of 20 mg kg(-1) body weight daily for the last 3 weeks of the experiment. The cholesterol-rich diet significantly increased plasma total lipid, total cholesterol and phospholipid levels in Groups 2 and 3 as compared with normally fed dogs' pre-experiment values of Groups 2 and 3 (p < 0.05). Also, erythrocyte and erythrocyte membrane total lipid, cholesterol and phospholipid levels were significantly elevated by the cholesterol-rich diet in Groups 2 and 3 animals (p < 0.05). After 3 weeks of garlic oil administration in Group 3, plasma, erythrocyte and erythrocyte membrane total lipid, total cholesterol and phospholipid levels significantly decreased (p < 0.05) as compared to those in animals receiving cholesterol diet alone. However, their levels were still higher than in this group before the experiment and than those in control dogs. A comparison between Groups 2 and 3 shows that garlic oil had a reducing effect on plasma and erythrocytes and their membrane lipids, and prevents the alimentary hyperlipidaemia.Öğe Effect of sorted anions on the acid-base balance and growing in Japanese quails(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1997) Durgun, Z; Keskin, E; Kocabatmaz, M; Kececi, TIn the study, sixty, 3 weeks old Japanese quail chicks were used and divided equally to four groups. The control groups (I) were fed basal diet and group II, III, IV were fed diet containing 120 meq/kg NaHCO3, CaSO4 and CaHPO4 respectively. Blood samples were taken far measurement of pH, pCO(2), HCO3- and certain electrolytes levels at 0.th, 5.th. and 10.th. days and all chicks were weighed and feed intake was calculated at 0.th and 10. th. days of experimental period. Bicarbonate evidently increased blood pH, pCO(2), HCO3- and plasma Na Values and decreased plasma K values whereas sulfate consistently depressed blood pH, pCO(2), HCO3- and increased plasma K and Ca levels. CaHPO4 did not affect acid-base balance as much as CaSO4. In the study, the highest feed intake and the lowest weight gain were determined in control group although there were no striking differences among the other groups in respect of weight gain and feed intake.Öğe Selected haematological and biochemical values in ostrich chicks and growers(EUGEN ULMER GMBH CO, 2005) Durgun, Z; Keskin, E; Col, R; Atalay, BIn this study, some haematological and biochemical parameters were determined in healthy ostriches (Struthio camelus) of different ages. For this purpose 15 chicks and 13 growers obtained from a commercial hatchery in Konya environment were used. In blood samples, red blood cell counts, haemoglobin amount, haematocrit value, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, red blood cell size (mean corpuscular diameter), thrombocyte counts, white blood cell counts and percentage of leukocyte types were determined. Additionally, cholesterol, triacylglycerol, creatinine, creatinine kinase, glucose, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, total protein and albumin levels were measured in plasma samples. Although the red blood cell counts, haematocrit values, glucose levels and lymphocyte percentage of the chicks were lower than for growers, the heterophil percentage, total protein, cholesterol, triacylglycerol and creatinine kinase were higher than in growers. There was no significant difference in the other parameters investigated between chicks and growers. Based on the results, it was concluded that selected haematological and biochemical values were influenced by the age differences of the ostriches and the data obtained in the study could be useful to establish some baseline values for haematological and biochemical parameters in different ages of the ostriches.
