Short Communication Influence of Selected Cardiological Drugs on Oxidative Status
نویسندگان
چکیده
The aim of the study was to determine the effect of the often applied drugs in cardiovascular diseases (metoprolol, acetylsalicylic acid, simvastatin and molsidomine) on antioxidative/oxidative balance in vivo. The determination of oxidative status was based on measurements of concentration of: thiobarbituric acid reactive substances (TBARS – lipid peroxidation products), protein carbonyl groups (marker of proteins oxidative injury), nitrotyrosine (marker of NO-mediated tissue damage) and sulfhydryl groups (protein oxidation product). The assays were performed in the plasma and whole blood of rabbits after three weeks of daily intragastric administration of the drugs mentioned above. It was shown that all drugs except acetylsalicylic acid caused an increase in the plasma and hemolysate levels of TBARS. No changes in nitrotyrosine concentration were observed after drug administration. The content of carbonyl groups did not change after administration of metoprolol, but increased significantly after simvastatin and molsidomine administration. Blood sulfhydryl group concentration was not changed by metoprolol but it significantly decreased after acetylsalicylic acid and increased significantly after molsidomine administration.

متن کاملOxidative stress and Ramadan observance; a possible influence of associated dieting
Introduction: The effects of Ramadan observance and any associated dietary restriction upon oxidative stress are not well known. The topic has thus been examined in a brief systematic review of available literature concerning non-athletic but otherwise healthy subjects, patients with selected clinical conditions, and in athletes. Methods: Ovid/Medline and Google searches were supplemented by a ...

Aim: we conducted this study to investigate the role of Ramadan fasting on oxidative stress. Materials and method: 23 people (16 male, 7 female) aged between 25 and 65 years were recruited in this study. 10cc Venous blood samples were taken after 8- to 10- hours fasting on 2 different times: a week before Ramadan and at the end of Ramadan (day 27). Portions of the serum samples were used immedi...

Short communication: Influence of encapsulated pomegranate peel extract on the chemical and microbial quality of silver carp (Hypophthalmichthys molitrix Val. 1844) fillet during refrigerating storage
Silver carp fillets were treated with liposomal encapsulated and unencapsulated pomegranate peel extract at 0.5 and 1% w/w to evaluate the effect of the extracts on the shelf life of the fillets during 15 days of refrigerated storage. Quality changes of the samples were investigated in terms of total volatile basic nitrogen (TVB-N), peroxide value (PV), thiobarbituric acid (TBA) and microbial c...
