[Geomagnetic effects on hepatic function in different phases of the annual cycle].

Investigations on 496 Wistar rats have revealed that in winter geomagnetic deviations (GMD) have no effect on hepatic function of the intact animals. GMD in spring and summer provoked functional impairment of the liver while in autumn intact and CCl4 hepatitis rats exhibited GMD-related normalization of liver function. Thus, efficacy of physiotherapeutic correction of the liver depends on the phase of the annual cycle and geomagnetic situation.
