Abstract:
تعد ظاهرة الاجهاد التاكسدي من اهم الميكانيكيات المحتملة لاحداث الضرر في النظام الحيوي عند التعرض لانواع مختلفة من المؤثرات والعوامل البيئية، ولذا تكون الانظمة المضادة للتاكسد هي اول من يتاثر بالزيادة الحاصلة في تكوين الجذور الفعالة المؤكسدة. لذلك تهدف هذ | The phenomenon of excessive oxidation considered the most important mechanism that cause potential damage to vital system when exposed to different forms of environmental factors, so anti - oxidants systems are the first to be affected by the increase formation of oxidizing radicals. For this reason, This study aims to determine the extent of the effect of some environmental conditions on the Extra - cellular antioxidant system, determine the most affected part in this system, study the correlation of this damage with other variable and to identify the natural values of different antioxidant system components. The study was carried out in the district of Baquba city, capital of Diyala province during the period from 10 October 2013 to 1 May 2014, the study group included (160) individual divided into four group (40) persons working in the field of welding, (40) persons workers in the radiation and (40) persons smokers and compared with (40) healthy people (the control group), all individual included in this study were male with age rang (25 - 45 years).Requested blood samples were taken for laboratory testes including complete blood count, and measurement of the following biochemical parameters, total serum protein, serum albumin, serum zinc, serum copper, serum iron, serum glutathione and malondialdehyde. The results of the laboratory test elicited that, the most common abnormalities in this study were the presence of low level of glutathione zinc, and copper in individual in all three study group in compare with controlled group and the differences were statistically significant(p value<0.05, <0.001, <0.01 respectively), also low level of iron in radiation group in compare with controlled groups and the differences were statistically significant(p value<0.01), and low level of proteins and albumin in smoking group in compare with controlled group and the differences were statistically significant(p value<0.01).also results of the current study revealed increased in the level malondialdehyde (MDA) in all three study groups in compare with controlled group and the differences were statically significant (p value<0.01). and increased levels of protein and albumin in the radiation and welder group in compare with controlled groups and the differences were statistically significant(p value<0.05) and increased in the level of iron in welder and smokers compare with control group and the differences were statistically significant (p value<0.001). The results of other laboratory test which include the complete blood count show High levels of white blood cells in all study groups compare with control group and the differences were statically significant (p value<0.001), and High levels of neutrophil and lymphocyte in welder and radiation group compare with control group and the differences were statically significant (p value<0.001). Results of the current study also showed increased levels of hematocrit, and red blood cells count and platelets count in a smokers group compare with control group and the differences were statically significant (p value<0.01).also there is increased in red blood cells count in radiation group in compare with controlled group (p value<0.05) , and decreased in platelets count in radiation group in compared with controlled group (p value<0.05).
