ABSTRACT Anti-inflammatory effect of the edible mytilid bivalve Perna viridis was evaluated using formalin, carrageenan and dextran-induced paw oedema in mice. The whole mussel tissue without shell was first extracted with ethyl acetate and then successively with methanol and water:ethanol, 7:3 (aqueous/ethanol). Three doses (100, 500 and 1,000 mg/kg) of the extracts (methanol and aqueous/ethanol) were administered orally prior to the injection of inflammatory agents. The inflammation induced by formalin was inhibited by the administration of both extracts for 7 days and the activity was found to be higher for methanol than aqueous/ethanol extract. A dose-dependent reduction in paw thickness was observed for carrageenan-induced paw oedema on treatment with methanol and aqueous/ethanol extracts which was comparable to the standard drug diclofenac. The effect of extracts on dextran-induced oedema was less than that produced by the other two inflammatory stimulants.

    ABSTRACT: The methanol extract from Clerodendrum petasites S. Moore (CP extract) was assessed for anti-inflammatory and antipyretic activities on the experimental animal models. It was found that CP extract possessed moderate inhibitory activity on acute phase of inflammation in a dose-related manner as seen in ethyl phenylpropiolate-induced ear edema (ED(50)=2.34 mg/ear) as well as carrageenin-induced hind paw edema (ED(30)=420.41 mg/kg) in rats. However, CP extract did not elicit any inhibitory effect on arachidonic acid-induced hind paw edema in rats. In subchronic inflammatory model, CP extract provoked a significant reduction of transudation but had no effect on proliferative phase when tested in cotton pellet-induced granuloma model. CP extract also reduced the alkaline phosphatase activity in serum of rats in this animal model. Moreover, CP extract possessed an excellent antipyretic effect when tested in yeast-induced hyperthermic rats. It is postulated that the anti-inflammatory and antipyretic effects of CP extract are caused by the inhibition of the prostaglandin synthesis. Anyhow, CP extract did not possess any analgesic activity in acetic acid-induced writhing response in mice. The results obtained show that C. petasites has beneficial properties since it possesses potent antipyretic and moderate anti-inflammatory activities without ulcerogenic effect.

    ABSTRACT: The 5-hydroxy-3,6,7,3',4'-pentamethoxyflavone (artemetin) from Cordia verbenacea DC (Boraginaceae) showed marked anti-inflammatory activity using various experimental models in rats. Artemetin significantly inhibited carrageenin-induced paw edema following oral doses from 30.4 to 153.9 mg.kg-1. The doses of 102.6 and 153.9 mg.kg-1 showed an inhibitory effect similar to that of 50.0 mg.kg-1 of calcium phenylbutazone. The ED50 value of artemetin in rats was estimated to be 67.07 mg.kg-1. Repeated administration of artemetin at doses of 67.07 mg.kg-1 for a 6-day period reduced granuloma formation with a response comparable to that of 20.0 mg.kg-1 of calcium phenylbutazone. This same dose of artemetin also reduced the vascular permeability to intracutaneous histamine. Sub-acute toxicological experiments indicated a very low toxicity.

    ABSTRACT: Injection of formalin into a hind paw of rats produces localized inflammation and pain. The nociceptive effect of formalin, recorded as flinching/shaking of the injected paw, is biphasic. The present study shows that formalin-induced inflammation and edema (assessed by measurement of paw volume up to 24 h post-injection) is also biphasic, an early neurogenic component being followed by a later tissue-mediated response. Rapid initiation of edema is closely related to early phase nociception and is dependent on activity in primary afferent neurons and axon reflexes, but not on transmission of the noxious stimulus and the perception of pain itself. The major site responsible for down-regulating the inflammatory response, particularly in the later stages when tissue-mediated components are most heavily involved, appears to be located supraspinally. Down-regulation occurs principally by means of descending neuronal pathways but may also involve a secondary humoral component. The perhaps surprising dependence on neuronal mechanisms which this study demonstrates promotes spinal and peripheral sites as potential therapeutic targets in certain inflammatory conditions.
