Abstract
Cyclophosphamide (5 or 10 mg/kg p.o.) and Gold sodium thiomalate (0 or 40 mg/kg i.m.) inhibit after repeated administrations (5 days) all the phases of Nystatin edema, whereas a single administration is ineffective.d-Penicillamine (25 or 100 mg/kg p.o.) inhibits the early phases of Nystatin edema after a single administration whereas repeated administrations are almost ineffective. An early treatment with Cyclophosphamide (2.5 mg/kg p.o.) simply delays the appearance of the secondary lesions of adjuvant arthritis but inhibit the development of the primary lesions. A late treatment with Cyclophosphamide as well as both the types of treatment with Gold sodium thiomalate (10 mg/kg i.m.) are effective against primary and secondary lesions. The only effect ofd-Penicillamine (50 mg/kg p.o.) in adjuvant arthritis is a significant incaease of the intensity of secondary lesions during the late treatment. It is suggested that the anti-inflammatory activity of Cyclophosphamide does not depend exclusively upon its effective on some cell population committed in the inflammatory reactions.
