Effects of electromagnetic field, cisplatin and morphine on cytotoxicity and expression levels of DNA repair genes.

This in vitro study examined how morphine, a 50-Hz 0.50 mT electromagnetic field (intermittent), and cisplatin co-treatments affected DNA repair gene expression and cytotoxicity in MCF-7 and SH-SY5Y cells. Morphine alone was reported to down-regulate examined DNA repair genes, whereas morphine plus EMF did not…

Expressions of some antioxidant genes in SH-SY5Y cells treated with β-lapachone, morphine and electromagnetic field.

This in vitro study exposed SH-SY5Y cells to a 50 Hz, 0.50 mT electromagnetic field under intermittent or continuous conditions, alongside β-lapachone and/or morphine. The authors report condition-dependent changes in antioxidant gene expression, including decreased NQO1 and increased NQO2 under intermittent EMF…

Electromagnetic Field Could Protect SH-SY5Y Cells Against Cisplatin Cytotoxicity, But Not MCF-7 Cells.

This in vitro study exposed MCF-7 and SH-SY5Y cells to a 50 Hz, 0.50 mT electromagnetic field in combination with cisplatin and/or morphine. The combined "CDDP+Mor+EMF" condition showed higher cisplatin IC values than cisplatin alone and "CDDP+Mor" in both cell lines, consistent with reduced cisplatin cytotoxicity.…

Effects of extremely low frequency electromagnetic fields on morphine analgesia and tolerance in rats.

This animal study examined whether extremely low frequency electromagnetic field exposure alters morphine analgesia and tolerance in rats. Rats exposed to a 50 Hz magnetic field (reported as 5 mT) showed higher morphine analgesic effects than rats given morphine without field exposure. In morphine-tolerant rats,…
