[Preventive effect of Rhodiolae rosea in spontaneous liver carcinogenesis in a mice model of high-tumor strain].

Different schemes of Rhodiolae rosea usage per os for prophylaxis of mouse hereditary hepatomas have been studied. A long-term effect on stimulation of tissue integration, T-immune activity and sufficient decrease of tumour frequency has been shown for R. rosea usage in early ontogenesis. A short-term effect on tissue and immune parameters has been demonstrated for R. rosea usage in middle ontogenesis. High-tumour frequency (as in the control), but tumour size decrease (comparing to the control) has been noticed in this case. A tendency to synchronic alterations of tissue integration and T-immune activity has been established in these experiments. It can be attributed to the assumption of communication between tissue (local) and immune (common) defence from tumour growth in the organism.
