| Abstract | ||||
| THIS WORK aims to point out the influence of bone marrow transplantation (BMT) in protection of irradiated pregnant rats and suppression of oxidative stress. BMT was administered to rats, 1 h post gamma irradiation at the dose level of 2 Gy given at the 7th or 14th day of gestation. Rats were examined after 20 days from gestation to detect the physiological parameters of the mother and number of implantation sites and resorptions as well as length of foetuses and tails. Pregnant rats irradiated at the 7 th and 14th day of gestation showed reduction in live foetuses and length of foetuses and their tails and significant decrease in erythrocytes (RBCs), leucocytes (WBCs), haemoglobin content (Hb), and hematocrite percentage (Ht). Irradiation-induced an elevation in aldosteron and a drop in calcium (Ca). Glutathione levels showed significant decreases in blood while the content of serum thiobarbituric acid reactive substance (TBARS) showed significant increases. Lipid profile exhibited an increase in the concentrations of total cholesterol (TC), triglycerides (TG) and low lipoproteins cholesterol (LDL-C) with a significant decrease in high lipoproteins cholesterol (HDL-C) in both groups. BMT to irradiated pregnant rats induced significant amelioration in radiation- induced changes. BMT was shown to be effective in reducing physiological disorders and oxidative stress in pregnant rats reflected on minimizing embryonic injuries. | ||||
