The effect of orengedokuto on experimentally-inflamed rats.

The inhibitory effect of Orengedokuto on lipid peroxide and sialidase was investigated using rats affected with carrageenin cotton pellet-induced granuloma and adjuvant arthritis. As a result, in the case of rats with carrageenin cotton pellet-induced granuloma, a significant inhibitory effect on granuloma formation was observed in the Orengedokuto treated rats (150 mg/kg/day) which showed a decrease in serum lipid peroxide (p < 0.001) and an increase in acid soluble glycoprotein (p < 0.001). In the case of adjuvant-induced arthritic rats, however, the condition of the arthritis was not improved at all, and was even aggravated in spite of the decrease in serum lipid peroxide.
