Procedure! Thirty young adult male Crl:CD rats were. treated by single ^ intrapericoneal 1'jections with aqueous solutions ofy--------MMIB--------Jac 80 ing/kg/day for 3 days. One day^Afterthe final treatment, the 30 rats, 10 rats per group, were adoinlseeredyBBBnby incragastric intubation as a suspension in corn oil in single doses to determine the LD50 value. The surviving rats were weighed and observed during a 14-day recovery period and then sacrificed. The LD50 value was calculated from the mortality data using the method of D. J. Finney.** Another group of 30 male rats was treated by singleintraperitoneal Injection with aqueous solutions o^ul^BBIIHII^HUBBBi^ ^ mg/kg.
