[Electrolytic changes in the white mouse under the influence of weak magnetic fields].
On female white mice, the influence of weak magnetic fields on their electrolyte balance has been tested. Three types of magnetic fields, namely of a 50 HZ sinusoidal, a 50 Hz rectangular and a 10 Hz rectangular field have been applied, the latter mainly because of its similarity to some biologic rhythms and because some technical environments also tend to produce similar type of fields. The changes of electrolyte balance mentioned above were measured after one and seven days of exposure of the animals to those fields. The 50 Hz sinusoidal and 50 Hz rectangular type of the field shows - with the exception of Ca++ - no significant changes in the animals electrolyte balance, neither after one more after seven days. Ca++ levels however were in both cases significantly lower in test animals then in controls. A one days exposure to a 10 Hz rectangular field significantly lowers the Na+ and increases K+ levels. Almost reversed results are obtained after seven days, probably indicating overcompensation, after recovery. Since Na+ in liver homogenates after one days exposure is also low, we tend to hold the opinion that 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 above mentioned measured effects.
