The Production of Lymphomatosis in Mice of Known Genetic Constitution

Abstract

Lymphomatosis was produced in 10 of 48 mice painted 10 times (over a 69 day period beginning when they were 4-6 wks. old) with methylcholanthrene in soln. in commercial benzene. No tumors appeared in 50 control mice. In 2 of the painted mice, leucocytes counts of 90,000 and 139,000, respectively, were found.
