    ABSTRACT: This study was conducted to investigate the effects of frying, boiling and freezing processes on sulfamethazine (SMZ) residues in chick breast meat and liver. Chicks were fed with feed not containing sulfonamide residues for 30 days. After 30 days, the suspensions of SMZ (110 mg/kg) were given to 10 chicken by gavage to craw once daily for 5 days. After 35 day, all animals were slaughtered and their breast meat and liver were taken. The part of the tissues were stored in -20 degrees C freezer for 30 and 45 days. The levels of SMZ in raw, grilled and boiled and freezed tissues were determined by HPLC-DAD detector. As a result of the study, it has been determined that, boiling and grilling processes reduced the residues of SMZ at different rates in broiler tissues; storing in the deep freezer did not cause significant changes on drug residues.

    ABSTRACT: Twenty eight female Wistar rats weighing 150-200 g were used in this study and these animals were divided into 4 groups, each comprising 7 rats. The first group served as the control group, and groups 2, 3, and 4 were administered a single dose of 250 mg/ propolis, a single dose of 125 mg/ (1/2LD(50)) cypermethrin, and a single dose of 125 mg/ cypermethrin followed by a single dose of 250 mg/ propolis 30 min later, per os using a catheter, respectively. Twenty-four hours after propolis administration, blood and tissue (liver, kidney, and brain) samples were collected. Serum glucose, triglyceride, uric acid, cholesterol, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) activities/levels, plasma and tissue malondialdehyde (MDA) levels, and erythrocyte and tissue superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities were determined. Compared to group 1, significant increases in plasma and tissue MDA levels and kidney GSH-Px activity, and significant decreases in erythrocyte SOD and CAT, liver SOD and GSH-Px, kidney SOD and brain SOD, CAT and GSH-Px activities were determined in group 3. Compared to group 1, a significant increase in glucose and a significant decrease in triglyceride levels were determined in group 3. Values pertaining to group 4 were demonstrated to be closer to those of group 1.
