[Regulation of immuno- and hematopoiesis with asterin]

It was shown that asterin, a higher plant preparation, had a marked antiblastomic action and a favourable effect on differentiation of the precursor cells and blood cells. It accelerated proliferation, migration of the truncal hemopoietic cells and their transfer from the dormant state into the cellular cycle. It also changed the cell differentiation in the direction of myelopoiesis. The mechanism of the asterin's immunomodulating action was found to be associated with regulation of T-cellular immunity and T-dependent immune response.
