Abstract
Summary
A method is described for the use of groups of mice in serum level and excretion studies on penicillin.
A slight prolongation of penicillin in the body of the mouse resulted from the intramuscular administration of a penicillin-albumin complex and a suspension of penicillin in peanut oil.
