title: [The hemorheological effects of Lychnis chalcedonica L. extracts].
abstract: The hemorrheological effects of extracts from Maltese cross campion (Lychnis chalcedonica L.) prepared using 40% (I) and 70% (II) aqueous ethanol solutions were studied in vitro in comparison with tanakan on the model of high blood viscosity syndrome. Under the hyperthermia conditions, extracts I and II at a concentration of 1 x 10(-5) g/ml limited the growth of blood viscosity and thrombocyte aggregation and the drop in thrombocyte deformability. The effects of both extracts were comparable to those of tanakan. Prolonged (5 days) administration of extract I (daily dose, 150 mg/kg p.o) in rats with arterial hypertension (SHR) decreased the viscosity of whole blood and plasma, reduced the concentration of fibrinogen, and increased the deformability of erythrocytes. No reliable effects of the extracts in vivo upon the erythrocyte aggregation and hematocrit were observed.
