[The distribution of iodine-125 labeled alpha-fetoprotein in the animal organism and its accumulation in the tumor].

The distribution of iodine-125 labeled human alpha-fetoprotein in mice was studied after its intravenous injection. The maximal accumulation of alpha-fetoprotein in different tissues and organs of animals was observed mainly 5 hours after injection. Then the protein was gradually eliminated from the body.

[The effect of short-term daily temperature drops on the processes of organogenesis in Cucumis sativus L. under conditions of different photoperiods].

The effect of nightly temperature drops of different durations (2, 4, and 6 h) on the processes of apical and axillary meristem organogenesis was studied in young Cucumis sativus L. under short photoperiod (day/night, 10/14 h), long photoperiod (16/8 h), and continuous light. Nightly temperature drops for 2 h had no effect on cucumber development under all studied photoperiods; however, longer temperature drops (4-8 h) accelerated the development under long photoperiod and continuous light.

[Radionuclide evaluation of the intensity of beta-oxidation of fatty acids in the liver during experimental cholestasis].

Scintigraphy following intravenous administration of 0.1% solution of 11-(ortho-iodine-131-benzoylamino) undecoic acid to rabbits in experimental cholestasis has shown that the intensity of beta-oxidation of this fatty acid in the liver decreases on the 2nd day of cholestasis. Its biological half-life in the liver significantly increases, at an average, 1.
