[The relation of calcium biorhythms to helio-geophysical factors].

In the course of 64 days the calcium concentration was daily determined in the blood serum of 6 male rabbits. From the first to the 32nd day round of research the rabbits were intact, and from the 33rd to 64th day round they were singularly immunized with human antimeasles gamma-globulin. With the help of the original algorithm the monthly rhythms' hierarchy was determined in the individual calcium dynamics as well as in the dynamics of synchronously measured solar activity indexes. It is discovered that singular immunization turned the 10-day calcium biorhythms' phase in reverse direction failing to affect the mean level, period length and the amplitude of them. Normal half-month calcium biorhythms stood in an anti-phase position to the analogous Wolf numbers' change and solar radio emanation in the wave of 2800 MHz rhythms.
