A Test of the Hypothesis That ELF Magnetic Fields Affect Calcium Uptake in Rat Thymocytesin Vitro

Abstract The experiment's objective was to test the statistical hypothesis that a 60-min exposure of rat thymocytes in vitro to a unique combination of static and a.c. magnetic fields results in suppression of calcium influx triggered by concanavalin A (Con A). Con A (10 μg/ml) induced about a 50% increase in 45 Ca 2+ uptake relative to no Con A (control). Magnetic field exposures had no statistically significant effect on Con A-stimulated calcium uptake. The data did not support the hypothesis.
