[Monthly and daily biorhythms of amylase in the blood of healthy men and their relation with the rhythms in the external environment].

Examinations of the serum of young healthy men have revealed hierarchy of 10 biorhythms of various frequencies, describing amylase activity, ranging from 8 hrs to 1 month. The same mathematical method has helped detect the rhythm parameters of 9 environmental factors, their time course being recorded synchronously with the blood collection. Phase ratios of the monthly biorhythms of amylase activity and environmental rhythms are discussed, as are seasonal features of amylase daily biorhythms and geomagnetic activity daily rhythms.
