The present study demonstrates that exposure of bacteria to medium strength static magnetic fields can significantly alter antibiotic sensitivity. Cultures of Escherichia coli were exposed to fields produced by permanent magnets. Samples of bacterial cultures continuously growing in the presence and in the absence of static magnetic fields were left untreated or were treated with an antibiotic and measured at 45 min intervals for cell growth and survival. It was found that exposure of E. coli to the static fields significantly increased antibiotic resistance. Bioelectromagnetics 22:129-137, 2001. Published 2001 Wiley-Liss, Inc.

A procedure is described for the determination of total body water content of human subjects using 11- to 12-gm. doses of deuterium oxide (D2O), vacuum sublimation of serum samples, and quantitation of the deuterium by infrared spectrophotometry at 2510 cm.-1. The coefficient of variation based on day-to-day procedure reproducibility is less than 2%. D2O added to serum is completely recovered in the sublimation and assay operations. The D2O dilution procedure compares favorably with the tritium dilution technic, with values obtained on 45 out of 46 individuals falling within the ±3 combined S.D. limits for the two methods. The significance of the total body water data is discussed.
