Effect of Iron Enriched Bread Intake on the Oxidative Stress Indices in Male Wistar Rats

Abstract

Background: Contrary to the proven benefits of iron, few concerns in producing the oxidative stress is remained problematic. Objectives: The aim of the study was to evaluate the oxidative stress in the male Wistar rats fed bread supplemented with iron in different doses i.e., 35 (basic), 70 (two fold), 140 (four fold), and 210 mg/kg (six fold) with or without NaHCO3 (250 mg/kg). Methods: In this experimental study Iron, ceruloplasmin, ferritin, total iron binding capacity (TIBC), albumin, total protein, uric acid and plasma superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT), malondialdehyde (MDA), and total antioxidant capacity (TAC), were evaluated in 30 rats at the first and last day of the experiment (day 30). In addition, phytic acid levels were detected in all baked breads. The data were analyzed by ANOVA and t test procedure though SPSS statistical software version 20. Results: Serum iron level in rats that received basic level of iron plus NaHCO3 decreased significantly in the last day of the trial. Higher level of serum iron was seen in rats that received iron twofold, fourfold and sixfold and rats that received iron fourfold plus NaHCO3. Serum ceruloplasmin and ferritin in groups of rats that received fourfold level of iron plus NaHCO3 and rats that received

Effect of lead exposure during perinatal period on kidney of adult offspring in rat: A stereological study

“…In this study, no significant difference was found in the total volume or fractional volumes of the cortex or medulla between the experimental and control groups. However, Heidari et al (38), showed that the mean total volume of kidney in 0.13% lead acetate groups, increased compared to the control group in adult male rat. It was significant in groups that received lead acetate in their drinking water for 8 and 12 weeks and not for 4 weeks.…”

“…However, renal hypertrophy is not associated with hypertrophy of the glomeruli, and the rise of kidney weight and volume is due to hypertrophy of the proximal tubules (39), which is due to protein synthesis in these areas (38). Goyer et al (45) showed no changes in glomeruli, while signs of changes in glomerular cells became apparent 6 weeks after lead administration in rat.…”
