Abstract

1. Injections of carrageenin (1,25 mg/kg i.v.) from the 1st to the 3rd day and then each 2nd or 3rd day inhibited paw swelling in adjuvant arthritis of the rat during the time of treatment. Injections from the 11th to the 15th day were ineffective. The level of plasma kininogen was slightly decreased but the total complement serum level was significantly lowered. 2,5 and 3 mg carrageenin/kg respectively were toxic after repeated injections. After a single administration the levels of plasma kininogen and of total serum complement were decreased by 50% although paw swelling was not affected. 2. Pentosane polysulfoester (25 mg/kg i.v.) did not influence paw swelling despite daily administration from the 1st to the 17th day. Heparin (10 000 IE/kg i.v.) was likewise ineffective. 3. Single or repeated injections of compound 48/80 (0,125-0,5 mg/kg i.v.; 1-5 mg/kg i.p.; 3-6 mg/kg s.c.), reserpine (0,2 mg/kg i.p.), cyproheptadine (5 mg/kg i.v.), bromolysergic acid diethylamide (2 x 2 mg/kg i.v.) or metiamide (10 mg/kg i.v.) were without effect on paw swelling. Neither did compound 48/80 effect the complement serum level. 4. Daily administration of chloropromazine (4-10 mg/kg p.o.) or of promethazine (10-15 mg/kg s.c. or p.o.) inhibited...Continue Reading

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here
