The influence which the chronic exposure of rats to an alternating 50-Hz-magnetic field has on activating immunological response in their lymphocytes

Project No. BG10 #021

Status:

completed 12/1997

Aims:

The need for information on the influence of alternating 50-Hz-magnetic fields of different flux density on the intra-cellular calcium concentration of freshly isolated human lymphocytes and in cells of cultivated human leukaemia T-cell lines (testing Lindström's existing results). Goal: determining the effect of low frequency magnetic fields on the immune system

Activities/Methods:

17 rats were exposed for two weeks to a magnetic field of 50 Hz/100 µT or to simulated exposure; at the end of the exposure period blood samples were taken and lymphocytes isolated; analysis of 3741 cells; measurement of the intra-cellular calcium concentration; stimulation with concanavalin A.

Results:

In contrast to earlier results, simulated exposure cells showed a stronger capacity for stimulation (intermediate individual response and number of reacting cells).
