Abstract

Effectiveness of Omega-3 Fatty Acid in Protection from Magnetic Field Exposure During Pregnancy: An Experimental Rat Study Ugurkan Erkayiran, Tufan Arslanca. Effectiveness of Omega-3 Fatty Acid in Protection from Magnetic Field Exposure During Pregnancy: An Experimental Rat Study. Journal of Reproductive Medicine. Nov 2021. OBJECTIVE: Magnetic fields (MFs) can have several negative effects on the human body. This study aimed to reveal the relationship of adenosine deaminase enzyme (ADA), thyroid-stimulating hormone (TSH), and fetal neural degeneration (FND) with the curative effect of omega-3 fatty acids. STUDY DESIGN: Pregnant Wistar Albino rats (n=30) were separated into 3 groups: Group 1 (sham group), Group 2 (rats exposed to 20 microteslas [μT] for 1 h/day for 10 days), and Group 3 (rats exposed to 20 μT for 4 h/day for 10 days). Blood samples were taken on days 1, 10, and 17 to examine ADA and TSH. Neurodegeneration scores were ana-lyzed with microscopic examination. RESULTS: FND was determined to be greater in the rats exposed to the long-term MFs as compared to short- term MFs (p<0.05). There was a significant difference in terms of ADA and TSH in the rats that received short- and long-term MF as compared to the sham group (p<0.05). The mean scores were higher in the short- and long-term MF groups than in the sham group (p<0.05). ADA activity was found to be higher and TSH was lower in the short- and long-term MF groups (p<0.05). With the use of omega-3, positive alterations in myelin degeneration were observed in the groups exposed to short- and long-term MF (p<0.05). CONCLUSION: While both ADA and TSH increased in both short- and long-term MF exposure, long-term MFs affected FND more than short-term exposure. Although using omega-3 showed a protective effect on the MF- induced FND, it was only protective against short-term exposure. reproductivemedicine.com

Main findings

Compared with sham, magnetic field exposure (20 μT) was associated with higher ADA activity and lower TSH in both short- and long-term exposure groups (p<0.05). Fetal neural degeneration was greater with long-term versus short-term exposure (p<0.05). Omega-3 use was associated with positive alterations in myelin degeneration in exposed groups (p<0.05), and was described as protective against MF-induced FND only for short-term exposure.
