BACKGROUND Although considerable evidence indicates neuronal Ca channels play significant roles in pain perception, their possible importance in hypersensitization after acute inflammation has not been investigated. METHODS Using carrageenan for inducing hypersensitization, the authors investigated the analgesic effects of intrathecally administered N- and P/Q-type channel blockers, omega-con...

Acacia farnesiana lectin-like protein (AFAL) is a chitin-binding protein and has been classified as phytohaemagglutinin from Phaseolus vulgaris (PHA). Legume lectins are examples for structural studies, and this family of proteins shows a remarkable conservation in primary, secondary, and tertiary structures. Lectins have ability to reduce the effects of inflammation caused by phlogistic agents...

We have studied the in vivo effects of carrageenan and trypan blue on the adoptive immunotherapy of an established local and disseminated syngeneic mouse FBL-3 lymphoma. Mice receiving 500 rads total-body irradiation before injection of FBL-3 tumor into the footpad were treated 4 to 5 days later when a palpable local tumor and disseminated metastases were present. Injection of in vivo immune ly...

in this study, we aimed to investigate the peripheral antinociception effects of specificphosphodiesterase 5 (pde-5) inhibitor vardenafil on carrageenan-induced nociception in rats,and the role of calcium besides the l-arginine- nitric oxide (no)- cyclic guanosine monophophate(cgmp) pathway in these effects. hyperalgesia was induced by the intraplantar injection of 0.1ml fresh carrageenan solut...

objective(s): fluvoxamine is a well-known selective serotonin reuptake inhibitor (ssri); despite its anti-inflammatory effect, little is known about the precise mechanisms involved. in our previous work, we found that ip administration of fluvoxamine produced a noticeable anti-inflammatory effect in carrageenan-induced paw edema in rats. in this study, we aimed to evaluate the effect of fluvoxa...

Anti-inflammatory activity of the ethanolic extract of the leaves of Morus indica Linn. was studied in wistar rats using the carrageenan induced left hind paw edema, carrageenan induced pleurisy and cotton pellet induced granuloma model. The ethanolic extract (100 mg/kg, p.o.) inhibited carrageenan induced rat paw edema. It also showed an inhibitory effect on leukocyte migration and a reduction...

OBJECTIVE The present study was designed to further investigate the effect of amitriptyline, a classical tricyclic antidepressant, on carrageenan-induced paw edema in rats. METHODS First, amitriptyline was administered intraperitoneally (i.p.) at doses of 20, 40 and 80 mg kg-1, 30 min before subplantar injection of carrageenan. Second, amitriptyline was given intracerebroventriculary or intra...

The effect of dietary undegraded carrageenan (Viscarin 402) on colon carcinogenesis was studied in female inbred F344 rats. Weanling rats were fed semipurified diets containing 0 or 15% undegraded carrageenan. At 7 weeks of age, all animals except controls were given azoxymethane (AOM) s.c. at a dose rate of 8 mg/kg body weight per week for 10 weeks or methylnitrosourea (MNU) intrarectally at a...

The adipose tissue-derived protein, adiponectin, has significant anti-inflammatory properties in a variety of disease conditions. Recent evidence that adiponectin and its receptors (AdipoR1 and AdipoR2) are expressed in central nervous system, suggests that it may also have a central modulatory role in pain and inflammation. This study set out to investigate the effects of exogenously applied r...

The peroxisome proliferator-activated receptor(PPAR) is a member of the nuclear receptor superfamily of ligand-dependent transcription factors related to retinoid, steroid, and thyroid hormone receptors. The aim of the present study was to evaluate the role of the PPARreceptor on the development of acute inflammation. To address this question, we used two animal models of acute inflammation (ca...
