title: The effect of pulsed electromagnetic fields on bone cell metabolism and calvaria resorption in vitro, and on calcium metabolism in the live rat.
abstract: The effects of three pulsed electromagnetic fields were investigated on bone cells and calvaria in culture, and on calcium metabolism in the live rat. No significant effect was seen on: 1) the proliferation of calvaria cells in culture; 2) alkaline phosphatase level, lactic acid release and collagen synthesis by confluent calvaria cells, with the exception of one pulse which produced a small increase in the latter when expressed as DNA; 3) resorption of calvaria in culture; 4) intestinal absorption, urinary excretion and net balance of calcium, bone formation and bone resorption in the live rat.
