The effect of alpha-lipoic acid on liver damage induced by extremely low-frequency electromagnetic fields in a rat model
This rat study assessed whether alpha-lipoic acid (ALA) modifies liver effects from extremely low-frequency magnetic field (ELF-MF) exposure. ELF-MF exposure (2 mT, 4 hours/day for 30 days) was associated with increased liver pathology and higher apoptosis markers (TUNEL, caspase-3) compared with other groups. ALA reduced several histopathological changes and lowered TUNEL/caspase-3, but did not improve fibrosis or biliary proliferation.
Key points
- Thirty-two male rats were randomized into control, ELF-MF, ELF-MF+ALA, and sham groups.
- ELF-MF exposure was 2 mT using Helmholtz coils for 4 hours/day over 30 days.
- The ELF-MF group showed increased liver hyperemia, inflammation, fibrosis, vacuolization, multiple nuclei, and biliary proliferation versus other groups.
- Apoptosis-related markers (TUNEL and caspase-3) were higher in the ELF-MF group than in other groups.
- ALA (100 mg/kg/day i.p.) given 1 hour before exposure reduced several ELF-MF-associated liver changes and reduced TUNEL/caspase-3.
- ALA did not significantly change bile duct proliferation or fibrosis compared with ELF-MF exposure alone.
- No pathological changes were reported in control or sham groups.
