Abstract (Swedish)
The alteration of release of calcium ions from biological tissue by electromagnetic stimulation has bien reported by several authors (Kaczmarec and Adey 1974:, Bawin et al. 1975, 1978; Bawin and Adey 1976; Blackman et al. 1979, l980a,å; Joines and Blackman 1980, l98l; Joines et al. l98O). Bawin etal. (1975) reported that 147 MHz radiofrequency (RF) electromagnetic radiation altered the release of calcium ions from chicken brains in vitro only at specific modulation frequencies between 6 and 20 Hz, with a peak at l6Hz. Similar findings have also been reported for human and other neuroblastoma cells (Dutta et ol. 1984, 1989). Further xamination of this phenornenon demonstrated the presence of power-density windows at different carrier... (More)

I det här dokumentet har vi försökt visa förekomsten av resonans
fenomen för tillströmning och utflöde av radioaktiva kalcium-45 joner i humana normala och transformerade lymfocyter och i råtthymocyter.

Abstract
The 'ion cyclotron resonance hypothesis' was explored by Liboff et al. (1987) in an experiment involving incorporation of calcium-45 (n5Ca2*) in mixed human lymphocytes. The geomagnetic horizontal field component was'adjusted to 2l pT. The experiment was first performed at an amplitude of the applied oscillating field of 150 pT and a sharp minimum was obtained at the frequency of l43Hz, which corresponds to the ion cyclotron frequency
at 2l p,T . The experiment was then repeated at an amplitude of 2l prT
and now a sharp, narrow maximum occurred at l4.3Hz.
Although there appears to be experimental evidence for resonance
phenomena, the cyclotron resonance hypothesis is shown to violate the laws of classical mechanics (Halle... (More)

Lednev (1990) and Hart (1990) treat quantum mechanically the interaction of a low-frequency field with an ion bound loosely to a membrane surface in the presence of a static magnetic field, and claim evidence for resonancephenomena.
In the present paper we have tried to demonstrate the presence of resonance phenomena for influx and efflux of radioactive calcium-45 ions in human normal and transformed lymphocytes and in rat thymocytes. (Less)
