VERFAHREN ZUM NACHWEIS VON KREBSZELLEN.

摘要

In order to perform a rapid and corrrect diagnosis of cancer, cells taken from a patient are examined in vitro. The cells are first mixed with a solution of hematoporphyrin or a hematoporphyrin derivative and then isolated from the unreacted reagent. An ESR signal given by radicals contained in the cells is observed to determine whether the amplitude of the signal is significantly increased by the presence of cancerous cells. The results may be combined with those of a determination of a shift of the g-value caused by the presence of cancerous cells.
