Effect of aqueous salt solutions treated with weak magnetic fields on the intrinsic fluorescence of bovine serum albumin. Isolation from these solutions and partial characterization of the biologically active fluorescing fraction

It was shown that water with additions of Ca2+, Na+, K+ and Cl- ions prelim inarily treated with. weak combined constant (42 mu T) and low-frequency al ternating (0,06 mu T) magnetic fields affects the intrinsic fluorescence of bovine serum albumin, the magnitude of the effect being, dependent on the frequency of the alternating field and ionic composition of the aqueous sal t solution. A practically complete transfer of the effect through a small p ortion of the solution treated with magnetic fields was revealed. It was al so found that after magnetic treatment, the solution contains a rather larg e (molecular mass 700-900 D) and stable molecular associate, which possesse s, at least partially, the properties and characteristics inherent in the w hole solution,that were as acquired as a result of magnetic treatment.
