To study the cellular response of blood and hepatic tissue to different doses of γ-irradiation.
Although relative viscosity and conductivity of hemoglobin were significantly elevated in rats exposed to a single dose of 2 Gy, these elevations were statistically non significant in irradiated rats exposed to 4 and 6 Gy as compared to control animals. Serum levels of pro-inflammatory cytokines were significantly elevated in addition to up-regulation of hepatic NF-кB and down-regulation of p53 and p21 in irradiated groups.
Elevated levels of hepatic NF-κB mRNA and low levels of p53 mRNA prove lack of apoptosis and induction of the inflammatory pathway in hepatic cells to face the harmful effects of the present γ-irradiated model.
