Abstract:
Objectives: To investigate the toxic effects occurring in the liver tissues of the pregnant rats and the fetuses, which are administered acrylamide and vitamin E as a protector during pregnancy.
Materials and methods: This research was conducted with the permission of Laboratory Animals Ethical Board of Inonu University Faculty of Medicine. Forty rats, of which their pregnancy is validated via vaginal smear, were distributed into five different groups. On the 20th day of pregnancy, pregnant rats and fetuses are decapitated. Malondialdehyde (MDA), reduced glutathione (GSH), total antioxidant status (TAS), total oxidant status (TOS) and xanthine oxidase (XO) levels were measured in the liver samples taken from mother and fetuses.
Results: It was detected that acrylamide administered during pregnancy increased MDA, TOS, XO levels statistically significantly and decreased the GSH level (p <= 0.05) in the pregnant rat liver tissue when compared to all other groups. In the vitamin E administered group; GSH, TAS levels significantly increased statistically and TOS and XO levels dropped to levels of the control group (p <= 0.05), in comparison to all other groups. Among all groups, no biochemical changes were observed in the fetus liver tissue (p > 0.05).
Conclusion: The liver of pregnant rats functions as a protective pre-filter by detoxifying acrylamide effectively and the acrylamide that reaches fetus liver is detoxified by the cytochrome P-450 system of the fetus liver. To be able to figure out the biochemical mechanism, more advanced studies are needed.
