ABSTRACT
It has been shown on a photomultiplier (PM) that glycine solution excited with quartz lamp of low intensity acquires the ability to produce ultra-weak ultraviolet radiation--mitogenetic radiation. The appearance of radiation is connected with the process of oxidative deamination of glycine molecules. These data confirm the formerly established facts of glycine mitogenetic radiation determined by biological detection.

The reaction of sarcoplasmic molecular organization on the irritation of the sympathetic system was studied in tired frog muscles. The molecular changes have been determined by registration of mitogenic irradiation. The intensive irradiation recorded at the phase of highest sympathetic effect indicated the reinforcement of the regulation process it is suggested that structural and energetic substrate changes associated with irradiation are directly involved in the modulating influences of the sympathetic system.

Changes in the molecular substrate of the frog gastrocnemius muscle sarcoplasm were studied at rest, under indirect suprathreshold stimulation and fatigue. The time course of changes in the sarcoplasm was evaluated from the intensity of recordable mitogenetic radiation of the muscle. At rest the muscle sarcoplasm was characterized by active maintenance of the functional integrity of nerve and muscle fibers, whereas under indirect stimulation and during fatigue this coordinating function was disturbed. Thus, the sarcoplasm is an important link in the regulation of coordinated changes in different structural elements of the muscle.

Mitogenetic radiation of the rabbit liver was studied in experiments in vivo after glucose injection as well as after glucose exposure combined with a slight electric stimulation of the vagus nerve. It was shown that the curve of mitogenetic radiation related to glucose injection disintegrates, with concurrent stimulation of the vagus nerve, into separate peaks. Such changes in radiation are considered as a manifestation of the regulatory actin of cell fields on the substrate structure.
