Vitamin E interfered with antioxidant capacity and energy metabolism damage from cell phone radiation in pregnant and fetal rats.

Plain English Summary

Summary written for general audiences

Radiation exposure decreased SOD and GSH-Px activity and increased MDA levels in both pregnant and fetal rats, and caused mitochondrial swelling, edema, and chromatin condensation in fetal brain tissue. Vitamin E supplementation reversed these changes in a dose-dependent manner, with all three doses increasing SOD and GSH-Px in fetal rats, and middle and high doses decreasing MDA in fetal rats and high dose doing so in pregnant rats.

Why This Matters

The researchers examined the right hippocampus of fetal rats under an electron microscope and measured SOD, GSH-Px, and MDA in brain tissue. No apoptosis was observed in any group, and the high vitamin E group showed uniform chromatin, abundant mitochondria, rough endoplasmic reticulum, and free ribosomes. The authors concluded that vitamin E interferes with radiation-induced damage to antioxidant capacity and energy metabolism in pregnant and fetal rats.

Exposure Information

Specific exposure levels were not quantified in this study. The study examined exposure from: 900MH cell phone Duration: one hour each time for three times per day for 21 days

Under the experimental dosage, vitamin E has certain interference on damage of antioxidant capacity and energy metabolization induced by electromagnetic radiation of cell phone in pregnant rats and fetal rats.

Quick Questions About This Study

The low, middle, and high vitamin E groups received 5, 15, and 30 mg/ml vitamin E respectively from the first day of pregnancy.
Radiation significantly decreased SOD and GSH-Px activity and increased MDA content in both pregnant and fetal rats.
In fetal rats, all three vitamin E doses increased SOD and GSH-Px activity, while middle and high doses decreased MDA. In pregnant rats, high dose increased SOD and GSH-Px and decreased MDA, and middle dose increased only SOD.
Radiation caused mitochondrial swelling, capillary edema, chromatin condensation, and vascular endothelial cell bubbles in fetal rats. Middle and high vitamin E doses made these changes inconspicuous, and high dose showed uniform chromatin and abundant mitochondria.
