Evaluation of the anti-inflammatory property of the extract of <Emphasis Type="Italic">Combretum micranthum</Emphasis> G. Don (Combretaceae)

A methanol extract of Combretum micranthum leaves was studied for anti-inflammatory activity in rats and mice using the carrageenan-induced rat paw oedema and the acetic acid-induced vascular permeability in mice. The effect of the extract on cellular-type inflammation was also investigated in the cotton pellet granuloma in rats. The extract (50, 100 mg/kg) significantly (P < 0.05) inhibited oedema production induced by carrageenan in rats. Increased vascular permeability caused by acetic acid injection was also inhibited by the extract, within the same dose range. C. micranthum extract (100 mg/kg) inhibited granuloma formation in rats to a similar degree as indomethacin (5 mg/kg). These results provide evidence for the anti-inflammatory property of C. micranthum leaves.

Evaluation of the anti-inflammatory and analgesic properties of the extract of Russelia equisetiformis (Schlecht &; Cham) Scrophulariacae

A methanolic extract of Russelia equisetiformis whole plant was studied for anti-inflammatory and analgesic activities in rats and mice using carrageenan-induced rat paw oedema, aceticacid-induced writhing and tail-flick test. The extract, at 10, 20 and 40 mg/kg, significantly (P <0.05) inhibited carrageenan-induced oedema in rats. Abdominal constriction induced by acetic acid was also inhibited by the extract, within the same dose range. The extract at the same dose also prolonged the latency period in the tail-flick response test, which was reverted by naloxone. The results suggested that the extract possesses potential anti-inflammatory and analgesic properties.

Analgesic and anti-inflammatory activities of total extract and individual fractions of Chinese medicinal ants Polyrhachis lamellidens

The ethanol extract of Chinese medicinal ants Polyrhachis lamelliden was evaluated for its analgesic and anti-inflammatory activities in mice. It was shown that the extract significantly inhibited acetic acid-induced writhing response and increased hot-plate pain threshold of mice at doses of 1.5 and 3.0 g crude drug/kg. Meanwhile, the extract significantly inhibited the increase in vascular permeability induced by acetic acid and in ear edema induced by xylene in mice. However, it had no obvious effect on leukocyte migration induced by carboxymethylcellulose sodium (CMC-Na). The ethanol extract suspended in water was partitioned with diethyl ether, ethyl acetate and n-butanol successively to yield four fractions including water fraction. Among these fractions, diethyl ether and ethyl acetate fractions were found to increase hot-plate pain threshold and to inhibit acetic acid-induced writhing response in mice. Water fractions markedly inhibited acetic acid-induced writhing response and reduced the dye leakage to the peritoneal cavity induced by acetic acid and ear edema induced by xylene. These results suggest that P. lamellidens presents remarkable analgesic and anti-inflammatory activity, which supported the traditional use of the medicinal ants in the treatment of various diseases associated with inflammation. The diethyl ether fraction has greater contribution to the overall analgesic activity, whereas the water fraction showed the greatest anti-inflammatory and peripheral analgesic activities.

Anti-inflammatory Properties of Amaranthus spinosus Leaf Extract

The methanol extract of Amaranthus spinosus L. leaves was evaluated for anti-inflammatory activities in different animal models. The effect of the plant extract was also studied on castor oil–induced diarrhea and gastric mucosal integrity. The extract (25–100 mg/kg) inhibited the carrageenan-induced rat paw edema and produced significant (p < 0.05) inhibition of acetic acid–induced increased vascular permeability. Inhibition of the cotton pellet granuloma was also inhibited by 100 mg/kg of the plant extract. Analgesic activity was exhibited with the significant and dose-related reduction in the number of writhings induced with acetic acid, as well reduction in paw licking induced by injection of formalin in mice. The extract (50 and 100 mg/kg) produced gastric erosion in rats, following repeated administration for 4 days, and with 25–100 mg/kg of the extract, there was a statistically significant (p < 0.05) reduction in castor oil–induced diarrhea in rats. These results demonstrate the anti-inflammatory properties of the leaf extract of A. spinosus. It is also suggested that the plant extract probably acts by the inhibition of prostaglandin biosynthesis.

Antiallergic and anti-inflammatory properties of the ethanolic extract from Gleditsia sinensis

This study was carried out to determine the effects of the 70% ethanolic extract from the anomalous fruits of Gleditsia sinensis LAM. (AFGS) on experimental allergic reactions and inflammation. AFGS (200, 500, 1000 mg/kg, p.o.) dose-dependently inhibited the systemic anaphylactic shock induced by compound 48/80 in mice and cutaneous reactions induced by histamine or serotonin in rats. At doses of 500 and 1000 mg/kg, AFGS showed a clear inhibition on homologous passive cutaneous anaphylaxis in rats. In vitro, AFGS significantly reduced histamine release from rat peritoneal mast cells triggered by compound 48/80 at concentrations of 20 and 50 micro/ml. Moreover, AFGS (500, 1000 mg/kg, p.o.) showed a significant inhibition on the hind paw edema in rats and ear swelling in mice caused by carrageenin and croton oil, respectively. It also clearly inhibited the vascular permeability induced by acetic acid in mice at a dose of 1000 mg/kg. These findings demonstrate that the ethanolic extract from the anomalous fruits of Gleditsia sinensis possesses antiallergic and anti-inflammatory activities, which may be mediated by reducing the release of mediators such as histamine from mast cells and weakening the inflammatory action of these mediators.

Anti-inflammatory activity of propolis

Propolis (bee-glue), known as a folk medicine, is a lipophilic material found in honeybee hives. In the present study on the anti-inflammatory effect of Korean propolis, it was extracted with ethanol, and used as a test material. The LD₅₀ value with the oral administration of ethanolic extract of Korean propolis (EEKP) was higher than 2 g/kg in mice. The oral administration of the propolis extract (100 mg/kg) significantly inhibited the development of hind paw edema induced by carrageenin in rats. The oral pretreatment of the propolis extract markedly inhibited the increase in vascular permeability and the number of writhing induced by acetic acid in mice. Propolis extract, 50 and 100 mg/kg p.o. per day for 7 days, produced a significant inhibitory effect on granuloma and exudate formation in rats. This inhibitory effect was enhanced with the concomitant use of prednisolone (2.5 mg/kg). These results suggest that Korean propolis apparently has a strong anti-inflammatory activity.
