title: [The development of methylcholanthrene-tumors in mice under the environmental influence of various electrobioclimatological conditions (author's transl)].
abstract: Comparative analyses of the development rate of a slow Tumor (Methylcholanthrene) in mice were undertaken under conditions of a) an electrostatic field (Field strength 200 V/m, Residual sinus component 0.1%), b) a Faraday cage (Shielding effectivity on atmospheric electrical disturbances: 99%) and c) a laboratory, climatized with conventional methods. The tumor was initiated in each case following a 6-week acclimatisation period to the unaccustomed surroundings. Following this, we observed the appearance rates over a period of 8 months at 14-day intervals. Under customary laboratory conditions these were perceptibly higher than in the electrostatic field or in the Faraday cage. No difference was apparent between the two latter conditions. Any variations in the electrobioclimatological environment can lead to stress reactions resulting in familiar consequences to various defense mechanisms. This allows us to find an explanation for the results otherwise difficult to interpret; for both in the electrostatic field and under shielding from external electrical influences the neoplastic activity was obviously reduced in comparison to normally climatized laboratory conditions. We are continuing the experiments.
