Antioxidant Vitamins and Microminerals in Cows With Foot-And Disease
(Agricultural Research Communication Centre, 2014) Yoruk, I. H.; Tanritanir, P.; Dede, S.; Ceylan, E.; Ragbetli, C.
Foot and-mouth disease (FMD) is an acute, highly contagious inflammatory viral disease of domestic and wild animals which causes decrease in productivity and lead to mortality. This study was conducted to investigate the levels of copper, zinc, magnesium and iron, alpha-tocopherol, vitamin D-3, vitamin C and lipid peroxidation in cow with foot-and-mouth disease. Sixty native black cows infected by foot-and-mouth disease and twenty healthy controls were selected for the study after clinical and serological examination. In the diseased animals, the malondialdehyde (p<0.00) and-copper (p<0.001) levels were increased while the vitamin C, alpha-tocopherol (p<0.001), vitamin D3 (p<0.05) magnesium (p<0.001) and iron (p<0.005) levels were decreased relative to controls. Although the zinc level was not changed, the Cu/Zn ratio was elevated in the diseased group. The obsereved changes may be the result of secondary infections due to suppressed immune system and losses of tissue and mucosa associated with foot-and-mouth disease.
Catalase Activity, Serum Trace Element and Heavy Metal Concentrations, and Vitamin A, D and E Levels in Pre-Eclampsia
(Sage Publications Ltd, 2008) Kolusari, A.; Kurdoglu, M.; Yildizhan, R.; Adali, E.; Edirne, T.; Cebi, A.; Yoruk, I. H.
Catalase (antioxidant enzyme) activity in erythrocytes and serum levels of trace elements (copper, iron, zinc), heavy metals (cadmium, cobalt) and vitamins A (retinol), D (cholecalciferol) and E (alpha-tocopherol) were measured in 145 subjects comprising 47 pre-eclamptic pregnant women (PE), 48 healthy pregnant women (HP) and 50 healthy non-pregnant controls (NP). Catalase, vitamins A, D and E and levels of cobalt were significantly lower in the PE group compared with the HP and NP groups, whereas levels of copper, iron and cadmium were significantly higher in the PE group than in the HP and NP groups. Levels of zinc were significantly lower in both the PE and HP groups compared with the NP group. This assessment of oxidant/antioxidant imbalance in pregnant women could be useful in the early identification of pre-eclampsia and antioxidant supplementation in the early weeks of gestation might be useful.
Catalase Activity, Serum Trace Element and Heavy Metal Concentrations, Vitamin A, Vitamin D and Vitamin E Levels in Hydatidiform Mole
(Imr Press, 2009) Kolusari, A.; Adali, E.; Kurdoglu, M.; Yildizhan, R.; Cebi, A.; Edirne, T.; Yoruk, I. H.
Purpose of investigation: In this study we aimed to measure the activity of catalase, which is an antioxidant enzyme, the concentrations of some trace elements and heavy metals, and vitamin A, D and E levels in serum samples of patients with hydatidiform mole, normal pregnancies and healthy non pregnant women. Methods: Seventy-two women were enrolled in this study. Of these, 24 were healthy women in the first trimester of pregnancy (HP), 24 were healthy non-pregnant women (NP) and 24 were patients with complete hydatidiform mole (CHM). Results: Serum levels of catalase, Zn, Co, vitamin A, D and E were significantly lower in the CHM group when compared with the HP and NP groups (p < 0.001). Serum levels of Cu, Fe, and Cd were significantly higher in the CHM group when compared with the HP and NP groups (p < 0.001). Conclusion: The assessment of oxidant/antioxidant imbalance in pregnant women could be useful in the early determination of molar pregnancy and supplementation with antioxidants may be useful in the treatment of CHM, and may prevent recurrent molar pregnancy.
Detection of Free Sugars in Almond Genotypes From Eastern and Western Turkey by Hplc
(Asian Journal of Chemistry, 2007) Balta, M. Fikret; Yoruk, I. H.; Kazankaya, A.; Battal, P.; Erez, M. E.
This study evaluated the sugar contents in almond [Prunus dulcis (Mill.) D.A. Webb.] genotypes, depending on their kernel sizes and kernel colours. Based on small kernel (SK) and large kernels (LK), sugar contents were compared both in sweet kernelled almond genotypes from Balikesir (western Anatolia, Turkey) and in bitter kernelled almond genotypes from Tunceli (eastern Anatolia, Turkey). Sugar contents were detected by HPLC. In all sweet and bitter LK and SK genotypes, contents of sucrose, maltose, glucose and fructose did not differ statistically except for only fructose content in bitter almonds. The LK and SK sweet genotypes contained 2.14-2.79 g/100 g sucrose, 0.61-0.44 g/100 g maltose, 1.20-2.05 g/100 g glucose and 3.28-3.45 g/100 g fructose, respectively. The LK and SK bitter genotypes contained 3.08-1.80 g/100 g sucrose, 0.85-1.34 g/100 g maltose, 2.28-2.38 g/100 g glucose and 3.67-2.73 g/100 g fructose, respectively. On the other hand, sugar contents were also compared based on light coloured kernel (LCK) and dark coloured kernel (DCK) in sweet and bitter genotypes. In sweet genotypes, sucrose, maltose and glucose contents of LCK and DCK did not differ statistically. In bitter genotypes, sucrose and glucose contents of LCK and DCK differed statistically. The sweet LCK and DCK genotypes contained 2.36-2.10 g/100 g sucrose, 0.60-0.74 g/100 g maltose, 1.58-2.32 g/100 g glucose and 3.28-2.56 g/100 g fructose, respectively. The bitter LCK and DCK genotypes contained 3.73-2.05 g/100 g sucrose, 1.10-1.36 g/100 g maltose, 3.56-1.56 g/100 g glucose and 2.63-4.05 g/100 g fructose, respectively. In addition, the mean sugar was usually fructose in LK, SK, LCK and DCK.
Effects of Plantago Major Extract on Serum Levels of Antioxidant Vitamins and Minerals in Broiler
(Agricultural Research Communication Centre, 2018) Dede, S.; Bingol, N. T.; Kilinc, D. Kilicalp; Deger, Y.; Yoruk, I. H.; Ekici, P. Tanritanir; Karsli, M. A.
The aim of this study was to evaluate the effects of Plantago major liquid extract on serum antioxidant vitamin and mineral concentrations of broiler. The experiment consisted of the control and 2 treatment groups, composed of 28 Ross 308 broiler chicks (Total, 84). A basal (control) diet was formulated. P Major was added to the control diet as following: PM1 (5 g/kg feed), PM2 (10 g/kg feed). The chicks were feed for 42 days ad libitum. The serum micronutrients (Retinol, alpha-tocopherol, vitamin D, calcium, magnesium, iron, manganese, and zinc) levels were determined. The retinol, alpha-tocopherol, Fe, Mg, Mn levels were not affected, and the Zn levels decreased in the PM1 and PM2. The supplementation of P. major has affected the serum vitamin D and Zn levels for this study, and should be analyzed for the alterations on the metabolism in subsequent studies.
