[Monthly and daily biorhythms of amylase in the blood of healthy men and their relation with the rhythms in the external environment]. / Mesiachnye i sutochnye bioritmy amilazy syvorotki krovi zdorovykh muzhchin i ikh sviaz' s ritmami vneshnei sredy.

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.

[Phase coordination of the rhythms of changes in solar activity and of the monthly biorhythms of altered cholesterol levels of the blood serum in rabbits]. / Fazovaia koordinatsiia ritmov izmeneniia solnechnoi aktivnosti i mesiachnykh bioritmov izmereniia kontsentratsii kholesterina v syvorotke krovi krolikov.

The concentration of total, free and bound cholesterol in the blood serum of 13 intact Chinchilla male rabbits was determined in two four-month experiments carried out in 1973-1974 and in 1984-1985 during a "minimum" phase of an 11-year solar activity cycle. A hierarchy of ten cholesterol biorhythms and solar activity rhythms were singled out on a computer, using an original algorithm, in the individual changes in cholesterol concentration in each rabbit and in changes in seven environmental indexes. A statistical stability of the frequency and phase of low-frequency cholesterol biorhythms and solar activity rhythms has been established within an 11-year period, the fluctuation amplitude of the indexes studied being, on the contrary, statistically unstable.

[The relation of calcium biorhythms to helio-geophysical factors]. / Sviaz' bioritmov kal'tsiia s gelio-geofizicheskimi faktorami.

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.

[Features of porphobilinogen synthesis from delta-aminolevulinic acid in the tissues of the internal organs of rats]. / Osobennosti biosinteza porfobilinogena iz delta-aminolevulinovoi kistolty v tkaniakh vnutrennikh organov krys.

The biosynthesis of porphobilinogen by homogenates of the lungs, heart, liver, kidneys, spleen, pancreas and small intestinal tissues was studied in 77 intact and in 68 rats with marked lead poisoning. The activity of ALA dehydratase in the lungs was decreased by 40.3%, in the kidneys by 40%, in the heart by 38.2% and was normal in homogenates of the liver, pancreas and small intestine. In spleen homogenates, the activity was increased by 26.3%. Potential mechanisms of different ALA dehydratase reactions in organs tissues of rats with lead poisoning are discussed.
