Pleura carcinosis. Cytomorphological findings with the mistletoe preparation iscador and other pharmaceuticals.

Over 160 cases of pleura carcinosis were treated systematically by local intrapleural instillation of Iscador, and the results were documented by cytomorphological examination of the punctate. The results show that, under these conditions, Iscador has two distinct activities, i.e. cytotoxic activity and immunostimulating activity.
