ELIMINATION OF MICROWAVE EFFECTS ON THE VITALITY OF NERVES AFTER ACTIVE TRANSPORT HAS BEEN BLOCKED
Authors not listed
Blocking the Na-K pump with ouabain eliminated the microwave effect on frog sciatic nerve survival time.
Plain English Summary
Researchers exposed paired frog sciatic nerves treated with ouabain to microwaves at a specific absorption rate of 10 W/kg while stimulating at 50 pulse pairs per second. At 50 ppps, ouabain reduced the half-decay time from about two hours to under 30 minutes, and microwave exposure caused no significant further shortening. At a lower stimulation rate of 5 ppps, half-decay times returned to near two hours and again showed no significant difference between exposed and unexposed nerves. The authors suggested that microwave effects on nerve vitality are associated with decay of ionic gradients normally maintained by active transport.
Why This Matters
Control experiments without microwave exposure showed that paired nerves had half-decay times within 15 percent of each other. Nerve temperature was maintained at 24 degrees Celsius plus or minus 0.05 degrees throughout each experiment. The researchers speculated that microwaves might directly interfere with the Na-K ATPase enzyme. They also speculated that microwaves could overburden the pump by causing extra sodium influx and potassium efflux. The authors noted that further experimental work is needed to substantiate these speculations.
