Prostaglandin receptors EP2, EP3, and IP mediate exudate formation in carrageenin-induced mouse pleurisy.
The roles of prostaglandins (PGs) as mediators of inflammation have been extensively studied, and production of PGI2 and PGE2 at inflammatory sites has been reported. However, it has not yet been clarified which type of PG receptors has a major role in inflammatory exudation. To examine in vivo role of PG receptors in inflammatory exudation, we induced pleurisy in PG receptors (IP, EP1, EP2, EP...
متن کاملFR167653, a cytokine synthesis inhibitor, exhibits anti-inflammatory effects early in rat carrageenin-induced pleurisy but no effect later.
We prepared a pharmacological profile of FR167653 (1-[7- (4-fluorophenyl)-1,2,3,4-tetrahydro-8-(4-pyridyl) pyrazolo[5,1-c][1,2,4]triazin-2-yl]-2-phenylethanedion sulfate monohydrate), a cytokine synthesis inhibitor, on early (5 h after irritation) and late (14-24 h after irritation) phases of rat carrageenin-induced pleurisy and on mediator-induced plasma exudation, in comparison with that of d...
متن کاملInvolvement of Nitric Oxide in a Rat Model of Carrageenin-Induced Pleurisy
Some evidence indicates that nitric oxide (NO) contributes to inflammation, while other evidence supports the opposite conclusion. To clarify the role of NO in inflammation, we studied carrageenin-induced pleurisy in rats treated with an NO donor (NOC-18), a substrate for NO formation (L-arginine), and/or an NO synthase inhibitor (S-(2-aminoethyl) isothiourea or N(G)-nitro-L-arginine). We asses...
متن کاملCaptopril uncovers kinin-dependent release of arachidonic acid metabolites in carrageenin-induced rat pleurisy.
As previously reported, pretreatment with captopril significantly enhanced pleural exudation of rat carrageenin-induced pleurisy. However, in high molecular weight kininogen-deficient rats (B/N-Katholiek), the pleural exudate volume was significantly less than that of the normal strain (B/N-Kitasato), and captopril pretreatment did not enhance exudation. In the present study, the following addi...
متن کاملInhibitory effects of proanthocyanidins from Ribes nigrum leaves on carrageenin acute inflammatory reactions induced in rats
BACKGROUND The anti-inflammatory effects of proanthocyanidins (PACs), isolated from blackcurrant (Ribes nigrum L.) leaves, were analysed using carrageenin-induced paw oedema and carrageenin-induced pleurisy in rats. RESULTS Pretreatment of the animals with PACs (10, 30, 60 and 100 mg/kg, i.p.) reduced paw oedema induced by carrageenin in a dose and time-dependent manner. PACs also inhibited d...
