W pracy zajmowano się grzybem nadrzewnym - modrzewnikiem lekarskim (Laricifomes officinalis). Z owocnika i mycelium officinalis oraz z grzybni hodowanego Lentinus edodes przygotowano frakcje i badano ich aktywność biologiczną w hodowlach komórek nowotworowych HeLa S3. Frakcje te przejawiały zróżnicowane działanie na badane hodowle. Stwierdzono, że najbardziej zaznaczone działanie cytotoksyczne wykazuje frakcja eterowa, natomiast kwas agarycynowy pobudza rozwój komórek linii HeLa.

This report deals with a study on biological activity of aqueous, ethanolic, and etheric extracts from Laricifomes officinalis fructification and mycelium in HeLa S3 cells cultures. For comparative purposes, effects of Lentinus edodes mycelium extracts on HeLa S3 cells, were also investigated. Protein concentration and lactate dehydrogenase, glucose-6- phosphate dehydrogenase, and catalase activities of cells homogenates, were assaysed following the incubation for 24 and 72 hours. Evidence was gained that Laricifomes officinalis etheric extracts exerted most pronounced cytotoxic or cytostatic action manifesting itself by protein content decrease and specific changes of enzymes activities in cells homogenates under test. Ethanolic and aqueous extracts from the investigated mushroom proved to produce less marked or differentiated cytotoxic effects. No cytotoxic activity of agaricic acid, was observed. Desiccation and powdering of mushroom's fructification was shown to decrease the effectiveness of cytotoxic agents being inclused in Laricifomes officinalis.
