Title

EFFECTS OF CENTRAL AND PERIPHERAL DEPLETION OF SEROTONERGIC SYSTEM ON CARRAGEENAN INDUCED PAW OEDEMA

Pages

  75-84

Abstract

 The role of serotonergic system was investigated on peripheral INFLAMMATION induced by intraplantary injection of CARRAGEENAN. Para-chlorophenylalanine (pCPA) was administered intracerebroventriculary (50, 100 μg/rat) or intraperitoneally (150 mg/kg, 3 days) and INFLAMMATION was induced by injection of CARRAGEENAN, 2 hours and 1 day later, respectively. Paw oedema was decreased significantly in pCPA-treated (100 μg/rat, i.c.v.) RATS compared to control groups. Injection of exogenous SEROTONIN (i.c.v.) by dose of 0.70 nmol/10μl/rat, but not the dose of 0.35 nmol/10μl/rat, 15 min after induction of INFLAMMATION completely reversed the anti-inflammatory effects of pCPA. MYELOPEROXIDASE activity in inflamed paws were reduced significantly in groups who received (either i.c.v. or i.p.) pCPA compared to controls. Exogenous SEROTONIN (0.70 nmol/10μl/rat) reduced inflammatory response when injected (i.c.v.) 30 min before or 30 min after the induction of INFLAMMATION. Injection of SEROTONIN at the time of induction of INFLAMMATION had no inflammatory/antiinflammatory effect. These results suggest that SEROTONIN, as a neurotransmitter in central nervous system, may be involved in modulating peripheral INFLAMMATION.
