“For 1 microgram/ml of 6-TG , pretreatment with adenosine increased survival from from 11% to 69% and from 5% to 24%, respectively, for 24- and 48-hr incubations (P less than or equal to 0.0005).”
“Inoculation of adenosine into mice (500 mg/kg of body weight) 1 hr prior to injection of lethal doses of 6-TG (50 mg/kg) increased the survival of the mice from 10% to 100% and from 20% to 80%, respectively, using two administration schedules.”
“When 0.3 microgram/ml of 6-TG was used, preincubation with adenosine increased the survival of CFUc from 25% to 80% and from 14% to 36% for 24- and 48-hr incubations, respectively (P less than or equal to 0.005).”
