Alterations in plasma and erythrocyte membrane fatty acid composition following exposure to toxic copper level affect membrane deformability and fluidity in female wistar rats.

Background: Deformability and fluidity function of the red blood cell membrane are properties defined by the lipid composition. Toxic copper level induces membrane lipid peroxidation which could cause membrane instability. This study therefore investigated the effect of exposure to toxic copper level for 30 days on red blood cell membrane deformability and fluidity in female Wistar rats.

Oral iron supplementation ameliorated alterations in iron uptake and utilization in copper-toxic female Wistar rats.

Objective: Women are more susceptible to both iron deficiency and copper toxicity due to monthly flow and estrogen action, respectively. Oral iron is beneficial for menstruating women and enhances erythropoiesis, but both deficiency and excess of copper impact iron absorption and mobilization. The aim of this study was to investigate the possibility of mitigating copper toxicity in female Wistar rats while supplementing with iron.
