The anti‐inflammatory effect of catecholamines in the peritoneal cavity and hind paw of the mouse

1Carrageenin or 5‐hydroxytryptamine‐induced oedema of the mouse hind paw was antagonized by catecholamines acting on both α‐ and β‐adrenoceptors.2Increased permeability of the mouse peritoneum induced by the local injection of acetic acid or pro‐inflammatory mediators was antagonized by catecholamines acting predominantly on β‐adrenoceptors.3The anti‐inflammatory effect of catecholamines was due neither to hyper‐glycaemia nor to the release of adrenal cortical hormones.
