[Effect of the cell dose on the development of 2 transplantable tumors in a syngeneic host].

The effects of different cell dose inoculation of plasmocitoma MOPC-315 and ADK-1t in Balb/c syngeneic mice are discussed in this work. Inoculated cell dose and neoplasia percent incidence have been noticed to be closely related, but unexpectedly two doses exist for each tumour, a comparatively small one and a definitely larger one, which cause nearly the same percent incidence. This paradox phenomenon is discussed also with reference to other researchers remarkers.
