    Determination of trace element and fatty acid levels in tissues of mirror and scaly carp (Cyprinus carpio L., 1758) living in Keban Dam Reservoir (Elazig)
    (Wiley, 2022) Aydin, Sevinc; Akkoyun, H. Turan; Akkoyun, Mahire Bayramoglu; Bengu, Aydin S.; Ekin, Suat; Harlioglu, Ayse G.
    This study investigated the concentrations of some accumulated trace metals (iron, manganese, zinc and copper) and fatty acids in liver and muscle tissues of mirror and scaly carp varieties (Cyprinus carpio L., 1758) living in Keban Dam Reservoir (Elazig), which is the second-largest artificial lake in Turkey that hosts commercially valuable and preferred fish varieties for human consumption. The inductively coupled plasma mass spectrometry (ICP-MS) method was used to analyse the concentrations of trace elements. Fatty acid levels were measured in a gas chromatography mass spectrometry (GC-MS) device, using a flame ionization detector (FID). Considering the two fish varieties and tissues that were studied, the mean metal concentrations (mu g g(-1)) were found in the following ranges: Fe 12.32-49.97, Mn 0.12-0.62, Zn 10.45-86.59 and Cu 2.74-11.86. Although the lowest levels were detected in the muscle tissue for all the metals examined, the levels in the liver tissue were significantly higher. According to the results of the analyses on fatty acid concentrations, the mean total saturated fatty acid levels in the muscle tissue of the scaly carp and mirror carp varieties were found to be 31.07 and 31.43 (%), respectively, whereas these values for the liver tissue were consecutively 22.36 and 22.08 (%). Successively, the mean total levels of unsaturated fatty acids were determined as 68.93 and 68.40 (%) in the muscle tissue and 77.64 and 77.92 in the liver tissue. This study, with the finding that the trace (metallic) element accumulation rates were below the upper limits of the tolerable range, and the examined fish varieties were rich in fatty acids, shows that mirror carp and scaly carp living in Keban Dam Reservoir are highly nutritious for human diets.

    Effects of Arbutin on Fatty Acid Levels of Erythrocyte and Serum in Wistar Albino Rats Treated with Potassium Bromate
    (Assoc Pharmaceutical Teachers India, 2022) Akkoyun, H. Turan; Aydin, Sevinc; Akkoyun, Mahire Bayramoglu; Bengu, Aydin Sukru; Ekin, Suat; Erdem, Sinem Aslan
    Background: In the presented study; the Effects of Arbutin (ARB) on the Rat Erythrocyte and serum fatty acid profile which is exposed to potassium bromate (KBrO3) were investigated. Materials and Methods: In this study, 32 Wistar albino rats weighing 250-300 g were used divided into 4 groups. Groups 1: control, group 2: KBrO3 (single dose 100 mg / kg gavage), group 3: ARB (50 mg / kg / day (ip) for 5 days), group 4: KBrO3 + ARB. At the end of the 5(th) day, alteration of fatty acid profile in erythrocyte and serum of rats in all groups was examined. Results: Rat serum essential fatty acid; palmitic acid (C16:0), myristic acid (C14:0), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), erythrocyte major fatty acids; palmitic acid (C16:0), myristic acid (C14:0), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), arachidic acid (C20:0), eicosenoic acid (C20:1), and lignoceric acid (C24:0). In addition, in our studied serum and erythrocytes; Total monounsaturated fatty acids (MUFA) varied between 8.91 +/- 0.53- 11.71 +/- 2.55 and 33.71 +/- 2.12- 37.11 +/- 2.12, respectively. It was determined that total polyunsaturated fatty acids (PUFA) varied between 5.90 +/- 1.29- 9.96 +/- 1.18 and 14.72 +/- 3.66- 22.13 +/- 4.82, respectively. Conclusion: In our study, alterations in fatty acid contents were observed, and results suggesting that arbutine affects the enzymes involved in Fatty acid metabolism and has an effect on fatty acid amounts.

    The protective effect of arbutin against potassium bromate-induced oxidative damage in the rat brain
    (Wiley, 2023) Akkoyun, H. Turan; Uyar, Ahmet; Akkoyun, Mahire Bayramoglu; Bengu, Aydin Sukru; Melek, Sule; Karagozoglu, Fatma; Aydin, Sevinc
    This study aimed to investigate the protective effects of arbutin (ARB) against brain injury induced in rats with potassium bromate (KBrO3). The rats were divided into four groups as Group 1: Control (0.9% NaCl ml/kg/day p.), Group 2: KBrO3 (100 mg/kg (gavage), Group 3: ARB (50 mg/kg/day p.), and Group 4: KBrO3 + ARB (100 mg/kg (gavage) + 50 mg/kg/day p.). At the end of the fifth day of the study, the rats in all groups were killed, and their brain tissues were collected. In the collected brain tissues, malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) levels were measured, and routine histopathological examinations were made. The MDA levels in the group that was exposed to KBrO3 were significantly higher than those in the control group (p < 0.001). In comparison to the KBrO3 group, the MDA levels in the KBrO3 + ARB group were significantly lower (p < 0.001). It was observed that SOD and CAT enzyme activity levels were significantly lower in the KBrO3 group compared to the control group (p < 0.001), while these levels were significantly higher in the KBrO3 + ARB group than in the KBrO3 group (p < 0.001). Additionally, the group that was subjected to KBrO3 toxicity, as well as ARB administration, had much lower levels of histopathologic signs than the group that was subjected to KBrO3 toxicity only. Consequently, it was found that KBrO3 exposure led to injury in the brain tissues of the rats, and using ARB was effective in preventing this injury.
