Abstract
The influence of weak magnetic fields on electrolyte balance was tested in female white mice. Three types of magnetic fields, i.e., a 50 Hz sinusidal, a 50 Hz rectangular and a 10 Hz rectangular field, were applied, the latter mainly because of its similarity to some biologic rhythms and because some technical environments also tend to produce similar types of fields. The changes of electrolyte balance were measured after 1 and 7 days of exposure of the animals to those fields. The 50 Hz sinusidal and 50 Hz rectangular type of the field shows, with the exception of Ca2+, no significant changes in the animals electrolyte balance after 7 days. Ca2+ levels were in both cases significantly lower in test animals than in controls. A 1 day exposure to a 10 Hz rectangular field significantly lowers the Na+ and increases K+ levels. Almost reversed results are obtained after 7 days, probably indicating overcompensation, after recovery. Since Na+ in liver homogenates after 1 days exposure is also low. Apparently, it must be excreted. Therefore, it should be of some interest to check the balance of those hormones (e.g., angiotensin, vasopressin) which are closely connected with the measured effects.
