title: [Humoral antitumor cytotoxins in patients with melanoma of the skin].
abstract: The level of humoral antitumor cytotoxins in sera of malignant melanoma patients has been studied by means of a cytotoxic test in vitro. The authors have shown a cytotoxic effect of sera of most patients on autochthonous tumor cells of melanoma. Hela cells were used as a control cell line. There was no cytotoxic effect of sera (of both melanoma patients and healthy donors) on Hela cells. The patients' sera cross-reacted in allogenic combinations of melanoma target cells and sera. Humoral cytotoxins against melanoma tumor cells have also been found tin sera of healthy donors.
