Abstract: | Summary The administration of ethionin to tissue cultures of fibroblastsin vitro causes a rapid and total inhibition of the growth of the transplanted tissues.It was observed that equimolar quantities of methionin are, on the contrary, well tolerated. The inhibition is therefore seen to be due to the dismetabolic activity of the antagonist.The contemporary administration of cholin is not able to restore the growth capacity of ethionin inhibited tissue cultures.In conclusion, ethionin produces a direct action on fibroblastsin vitro, probably intervening in the process of protein synthesis of the transplanted elements. |
