Smoking has been involved as a significant risk factor for series and establishment of diseases. The aim of our study to investigate smoking effects induced oxidative damage. We have chosen male students of Al-Iraqia University and Tikrit University, aged 20-23 years. In our study we measured activity of Lactate Dehydrogenase (LDH), Catalase (CAT), Superoxide Dismutase (SOD), and Glutathione Peroxidase (GXp). Our results showing that the level of LDH in smokers were higher than nonsmokers ,and the levels of CAT was higher in group of nonsmokers ,while SOD and GXp were higher significantly in non-smokers when comparison with smoker students. Also we study the height, body weight, body mass index (BMI), and some of blood parameters red blood cells (RBCs), White blood cells (WBCs), and hemoglobin (Hb). Results showing significant differences between smokers and nonsmokers, all of these parameters were lower in smokers. These results perhaps indicate that smoker students have oxidative stress and shortness in antioxidants defense system.
This study was conducted for the period from 09/2013 to 02/2014 at Samarra General Hospital labs with patients admitted in the corridors of recovery for the patients with angina pectoris; ratio to the disease of hypertension is the pressure measurement during a hospital, (50-65) age nonsmoker. Reveiew as results showed high significant in hypertension for people in hypertension , angina pectoris compared with the control group in,as well as high significant in lipid profile (cholesterol, triglycerides). the high increase in angina pectoris group compared hypertension with group compared with control group at the level( P <0.05 ). As for the lipoproteins, a decrease significant in the concentration of HDL-C was the largest decrease in angina pectoris when compared with hypertension group and the control group. at the same time high LDL-C concentration in a angina pectoris when compared with the control group, as to the biochemical variety results for increase significant in the concentration of blood sugar in the two study groups .show results high in angina pectoris when compared with hypertension group and the control group ,uric acid show results high in angina pectoris when compared with hypertension group and the control group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
