Influence of counter-irritation by carrageenin on inflammatory reactions induced by prostaglandins, serotonin, histamine, compound 48/80, carrageenin and Freund's complete adjuvant.
The carrageenin edema of rat paw and the primary phase of rat adjuvant arthritis were significantly inhibited by carrageenin whereas the increase of skin capillary permeability induced by prostaglandins (PGs) and further irritants as well as the secondary phase of adjuvant arthritis were mostly not significantly affected. Inhibitory effects after single carrageenin injection do not seem to be mediated by the complement system because total complement activity remained unaffected.
