The aim of the study was to determine blood concentration of essential trace elements (Se, Zn, Cu) and toxic metals (Pb, Cd), markers of antioxidant (activities of glutathione peroxidase (GPx), superoxidase dismutase and ceruloplasmin) and prooxidant processes (thiobarbituric acid reactive substances (TBARS)) in workers exposed to Pb and Cd. Forty three male workers of the lead-acid batteries d...

The influence of exercise combined with whole-body cryotherapy (WBC) on the oxidant/antioxidant balance in healthy men was assessed. The study included 16 kayakers of the Polish National Team, aged 22.7 ± 2.6, subjected to WBC (-120°C--145°C; 3 min) twice a day for the first 10 days of a 19-day physical training cycle: pre exercise morning stimulation and post exercise afternoon recovery. Blood...

Water extracts from selected Dracaena plants cultivated in greenhouse conditions were evaluated for antioxidant properties by vitro methods using the muscle tissue of Atlantic sturgeon (Acipenser oxyrinchus Mitchill). The level 2-thiobarbituric acid reactive substances (TBARS) and total capacity (TAC) after treatment derived leaves (in final concentration 10 mg.mL-1) assessed. When was incubate...

The aim of the study was to determine the concentration of lipid peroxidation products, the activity of selected antioxidant and lysosomal enzymes, and protease inhibitor in patients with renal cell carcinoma who underwent radical nephrectomy. The studied group included 44 patients: 21 of them underwent open surgery, while 23 underwent laparoscopy. Blood samples were collected three times: befo...

Oxidative stress and inflammatory mediators, such as IL-6, play an important role in the pathophysiology of acute pancreatitis. The study was aimed to assess the degree of the pro/antioxidative imbalance and estimate which antioxidant plays a role in the maintenance of pro/antioxidative balance during acute pancreatitis. The study was investigated in the blood of 32 patients with acute pancreat...

The pomegranate peel, an agricultural by-product or waste, is a rich source of bioactive compounds. In the current study, addition different concentrations peel hydromethanolic extract (PPE) into tahini was investigated. in ratio 1 : prepared, and PPE yield evaluated. HPLC Folin-Ciocalteu methods were used to determine phenolic compounds total content PPE, respectively. antioxidant activity inv...

This study investigated the influence of frying oil types and storage duration on acrylamide concentration, moisture variation pattern, thiobarbituric acid reactive substances (TBARS) content acceptability factors commonly consumed snack (chin-chin). A standard processing procedure was used to prepare (chin-chin) using a combination ingredients such as wheat flour, sugar, salt, margarine, groun...

BACKGROUND Pregnancy induced hypertension (PIH) is a state of extremely increased oxidative stress. Hence, research and test of role and significance of oxidative stress in hypertensive disturbance in pregnancy is very important. AIM Aims of this research were to determine a level of thiobarbituric acid reactive substance (TBARS) as oxidative stress marker in blood of pregnant woman with preg...

Isolated rat hepatocytes in culture were incubated with different concentrations of iron-sorbitol (50, 100, 150, and 200 µM) to assess the changes in reactive oxygen species (ROS) and lipid peroxidation leading to apoptotic hepatocyte cell death. The viability of hepatocytes was declined depending on the iron concentration. One hour incubation of the cells with 100 µM iron resulted in decreased...
