Abstract

Obesity is a rapidly growing epidemic worldwide, influenced by both genetic and environmental factors. The onset of obesity is due mainly to low energy expenditure (such as from exercise) combined with high caloric intake. The study was conducted on fifty obese individuals and fifty apparently healthy control individuals; the age was between (18-60) years. Blood samples obtained from Marjan Medical City in Babylon Province. The aim of this study to evaluate the differences of oxidant malondialdehyde (MDA), antioxidantenzyme superoxide dismutase (SOD),catalase (CAT), glutathione peroxidase (GPx), insulin resistance (IR) and lipid profile in sera of adult obese individuals and the control group. The results of present study revealed a significant increase in MDA (p<0.001), blood glucose (p<0.001), insulin (p<0.001), insulin resistance (p<0.001), total cholesterol (p<0.05), TG (p<0.001), VLDL-cholesterol (p<0.001) and LDL-cholesterol (p<0.001) concentration in sera of obese individuals whencompared to those of the control group. Also this study show significant decrease in SOD (p<0.001), CAT (p<0.001), GPx (p<0.001) and HDL-C (p<0.05) concentration in sera of obese individualswhen compared to those of the control group. The study concluded that obesity is associated with increase oxidative stress. The increase of MDA concentration and decrease of SOD, CAT and GPxconcentration may contribute in the development of complications of obesity.

Abstract

Background: Liver enzymes are commonly found in liver cells and when the liver is damaged, liver cells release their enzymes into the blood stream. Vitamin C is a low-weight molecular antioxidant and is effective in the aqueous phase in protecting different parts of cells against free radicals. An enzyme inhibitor is a molecule, which binds to enzymes and affect their activity.Objective: This study was carried out to investigate the effect of new vitamin C derivative on serum liver enzymes.Research design and methods: Eight samples were used. Liver enzymes activity measured with and without vitamin C derivative. Results: The result showed a reduced activity of aspartate aminotransferase (AST), and alanine transferase (ALT) after addition of vitamin C derivative.Conclusion: It is concluded that the decrease in ALT, and AST activities were due to noncompetitive inhibition of enzymes by vitamin C derivative.

أنزيمات الكبد موجودة عادة في خلايا الكبد وعند تلف الكبد يتم الإفراج عن الانزيمات الخاصة في مجرى الدم. فيتامين C هو منخفض الوزن الجزيئي للأكسدة وفعال في المرحلة المائية في حماية أجزاء مختلفة من الخلايا ضد الجذور الحرة. مثبط الإنزيم هو جزيء، الذي يرتبط بالانزيمات ويؤثر على نشاطهم. أجريت هذه الدراسة لمعرفة تأثيرمشتق فيتامين C الجديد على انزيمات الكبد في الدم. استخدمت ثمانية عينات. النشاط قياس انزيمات الكبد بدون ومع فيتامين C المشتق. أظهرت النتيجة انخفاض نشاط ASTو ALT بعد إضافة فيتامين C المشتق. ويستنتج من ذلك أن الانخفاض في ALT، AST نتيجة التثبيط غير التنافسي على الانزيمات الذي اظهره مشتق فيتامين C.
