Determination of Oxidant / Antioxidant Levels in Sheep With Hydatite Cyst in Liver
(Indian Journal of Forensic Medicine and Toxicology, 2020) Mahmood, E.A.K.; Handan, M.; Nihat, M.
The larval form of Echinococcus granulosus, hydatid cyst is an important parasitic zoonosis commonly seen in animals and humans. The aim of this study was to investigate the efficacy of oxidative stress on the pathogenesis of cystic echinococcosis with antioxidant / oxidant status in sheep sera. The material of the study was composed of sheep infected with hydatid cyst and healthy cut in slaughterhouse in Van province. The general health status of the sheep before slaughtering was checked by physical examination and blood samples were taken. After slaughtering, cyst hydatid examination was performed in different organs of the animals. The control group consisted of 25 sheep study cases with positive (fertil cyst) and 15 sheep without any pathological lesion on organ examinations and healthy on physical examination. Blood samples taken from animals infected with healthy and hydatid cysts were transported to the laboratory under appropriate conditions and centrifuged. Total antioxidant / oxidant status, paraoxonase and arylesterase activities were measured by using commercial kits. Compared with cystic echinococcosis group and healthy group, the importance was calculated on the TAS, PON1 activities (P <0.01), TOS, ARES activities differences (P <0.001), It decreases. This may cause tissue necrosis and increased inflammation . Decrease in antioxidant reserves; excessive free radical formation in the ewes with cystic echinococcosis causes deterioration of the normal histological structure of the organ in the cyst. © 2020, Indian Journal of Forensic Medicine and Toxicology.

Determination of the Level of Some Metals in Environment Water Sources Around Van
(Alpha Publishers, 2020) Mahmood, E.A.K.; Handan, M.; Nihat, M.
For healthy and safe drinking water supply, monitoring and controlling the water until it reaches the end consumer is very important, F,As, Cu, Fe, Mg, Ammonia analyzes were performed in the water samples taken from the villages of Van Bardakçı, Çitoren, Kevenli Gölyazı and Tabanlı at Yıldız University Faculty of Science and Van YY Central Laboratory. Thoroughly washed and rinsed with 1/50 diluted HCl and rinsed thoroughly into a transparent pet bottle. After 3-5 minutes of water to be sampled and rinsed at least 3 times with the same water, water samples were taken. According to these results, Cu level was found most in Gölyazı village, F, iron, ammonia and As in Tabanlı village, and Mg was found in the highest amount in Kevenli. The French hardness was found to be the highest in Tabanlı village. pH was found to be highest in Kevenli village and hardness was the highest in Gölyazı village. When the values obtained in this study are taken into consideration, it is seen that the composition of the waters of 4 different villages can be used as potable water, although their composition is different, except Tabanlı village that had high amount of As. It is necessary to find new water resources in this village and local authorities must give necessary importance fort this case. © 2020 the Author(s). All rights reserved.
