in view of evidence suggesting that 1.2 mega-units of `` '' all-purpose '' '' penicillin ( 300 000 iu potassium penicillin g , 300 000 iu procaine penicillin g and 600 000 iu benzathine penicillin ) did not maintain treponemicidal serum concentrations during the week following injection-which if true , might necessitate a reappraisal of prophylactic and treatment schedules in wide use against syphilis-daily assays were performed to determine the penicillinaemia levels in ambulant adult males for one week following intramuscular injection with this dosage of two `` '' all-purpose '' '' products ( 168 assays in all , 24 each day ) .
