[Use of chemiluminescence analysis in the determination of the activity of hepatic antichalone and chalone].

Partially purified antichalone and chalone from the liver of the mammals possess significant antiradical activity revealed by the chemiluminiscent analysis in the system capable of generating free radicals. Chemiluminiscent damping degree is proportional to the quantity of antichalone and chalone in the system. During the first three days the activity of antichalone is increased, while that of chalone in decreased in the liver of partially hepatectomized rats. In 14 days after partial hepatectomy the activity of both antichalone and chalone decreased, but their ratio is normalized. Thus, the regeneration of the liver in different periods after the operation takes place when the condition of antichalone/chalone system in the organ is unequal.
