Pharmacology and Toxicology of Extract from Arcangelisia gusanlung

Objective To study the pharmacology and toxicology of the extracts from Arcangelisia gusanlung(EAG). Methods The anti-inflammatory activities were investigated using various inflammatory models including ear edema induced by xylene in mice, paw edema induced by carrageenan, and cotton pellet granuloma in rats. The analgesic effect was observed in hot-plate test and writhing test in mice and the antipyretic effect was observed in rat fever model induced by yeast. The antitussive action was tested in mice by sequential method and expectorant action was evaluated by tracheal excretion of phenol red. The antidiarrhea function was observed on normal intestinal propulsion of mouse model of diarrhea induced by decoction of Sennae Folium. The toxicity was measured by toxicological experiment.Results Each dose of EAG could significantly inhibit the paw edema, cotton pellet granuloma, and intestinal propulsion. EAG significantly reduced writhing times and amount of wet manure. Obvious antipyretic action to fevered rat was observed. EAG obviously increased the tracheal excretion of phenol red and prolonged the latency of cough. No toxic reaction was shown in the observed period, and the maximum tolerance dose of mice was equivalent to 1360 times of common-used dose in human. Conclusion The clinical dosage of EAG is safe, and its anti-inflammatory, analgesia, antipyresis, antitussive, expectorant, and antidiarrhea effects are significant.     

Anti-inflammatory activity of Salacia oblonga Wall. and Azima tetracantha Lam.

The anti-inflammatory activity of Salacia oblonga rootbark powder and Azima tetracantha leaf powder was assayed in male albino rats using carrageenan-induced rat paw oedema (acute inflammation) and cotton pellet granuloma (chronic inflammation) methods. Both the crude drugs were maximally active at a dose of 1000 mg/kg. In the cotton pellet granuloma assay, these drugs were able to suppress the transudative, exudative and proliferative components of chronic inflammation. Furthermore, these drugs were able to lower the lipid peroxide content of exudate and liver, γ-glutamyl transpeptidase activity in the exudate of cotton pellet granuloma. The increased acid and alkaline phosphatase activity and decreased serum albumin in cotton pellet granulomatous rats were normalised after treatment with these drugs. It is likely that these drugs may exert their activity by antiproliferative, antioxidative and lysosomal membrane stabilization.

Anti-inflammatory activity of hexane leaf extract of Aspilia africana C.D. Adams

The anti-inflammatory activity of hexane leaf extract of Aspilia africana C.D. Adams (Compositae) was evaluated in rodents using the xylene-induced ear edema, egg albumin- and agar-induced paw edema, formaldehyde-induced arthritis, cotton pellet granuloma, gastric ulcerogenic, acetic acid-induced vascular permeability and dextran-induced in vivo leukocyte migration tests. Results showed that the extract (5mg/ear) inhibited topical edema in the mouse ear and at 200 and 400mg/kg (i.p.), it significantly (P<0.05) suppressed the development of egg albumin- and agar-induced paw edema, and the global edematous response to arthritis induced by formaldehyde in rats. Oral administration of the extract (200 or 400mg/kg) evoked a significant (P<0.05) dose-related ulceration of the rat gastric mucosa and inhibition of vascular permeability induced by acetic acid in mice. The extract also significantly (P<0.05) reduced total leukocyte and neutrophils counts in a non-dose-related manner. However, it significantly (P<0.05) increased lymphocyte counts and stimulated the growth of granuloma tissues induced by subcutaneously implanted cotton pellets in rats. Phytochemical tests showed that the extract contained sterols and terpenoids. These findings suggest that the leaves of Aspilia africana possess anti-inflammatory activity in acute and certain aspects of chronic inflammation, which may derive from inhibition of prostaglandins synthesis, inhibition of increased vascular permeability, inhibition of neutrophil migration into inflamed tissues, and stimulation of lymphocyte accumulation, which may enhance tissue repair and healing. The terpenoids present in the leaves may account for the anti-inflammatory activity.

Synergistic antiinflammatory effects of pinitol and glucosamine in rats

This study evaluated the antiinflammatory activities of pinitol and glucosamine either alone or in combination against carrageenan- and cotton pellet-induced acute and subacute inflammation in rats. Five groups were included in each of the acute and subacute inflammation studies: the vehicle control group, positive control group (aminopyrine 100 mg/kg), pinitol group (20 mg/kg), glucosamine group (25 mg/kg) and a pinitol (20 mg/kg) and glucosamine (25 mg/kg) combination group. When 20 mg/kg of pinitol was administered to the rats, paw edema induced by the carrageenan injection was significantly suppressed and the level of granuloma formation induced by the cotton pellet implantation was slightly reduced. When 25 mg/kg of glucosamine was administered, paw edema caused by the acute inflammation was slightly reduced and the level of granuloma formation caused by the subacute inflammation was strongly suppressed. Although the combined application of pinitol and glucosamine did not have an additional antiinflammatory effect on the paw edema caused by acute inflammation, it did have an increased antiinflammatory effect on the formation of granuloma induced by subacute inflammation. Therefore, pinitol and glucosamine have an antiinflammatory effect on acute and subacute conditions. Moreover, a synergistic antiinflammatory effect against subacute inflammation was observed when the two chemicals were administered in combination.
