Study type: Medical/biological study (experimental study)

Changes of leukocyte adherence ability under the influence of magnetic field in the course of a treatment of patients with laryngeal and pharyngeal carcinoma. med./bio.

Published in: Electromagn Biol Med 2008; 27 (3): 277-288

Aim of study (acc. to author)

To study the influence of 50 Hz magnetic sinusoidal magnetic field on the adherence ability of T lymphocytes of cancer patients in vitro.

Background/further details

The adherence ability of T lymphocytes was generally examined in 52 patients with laryngeal and pharyngeal carcinoma between the year 2000 and 2005 (data not given in this extract).
Additionally, the values of non-adhering cells in T lymphocytes samples of the cancer patients in dependency of magnetic field exposure vs. no exposure were compared in vitro in the course of the oncological treatment.

Main outcome of study (acc. to author)

The number of non-adherent T lymphocytes in was statistically significant lower under the influence of magnetic field exposure (T lymphocytes taken before the general oncological treatment as well as in the course of a successful treatment). There was no statistically significant difference between the effects with varying magnetic flux densities.
The magnetic field increased the adherence ability of T lymphocytes in patients with laryngeal and pharyngeal cancer in vitro.
