Effects of Orengedoku-to and Senkanmeimoku-to, traditional herbal medicines, on the experimental elevation of aqueous flare in pigmented rabbits.
We investigated the effects of Orengedoku-to (Huanglian-Jie-Du-Tang in Chinese) and Senkanmeimoku-to (Xygan-Ming-Mu-Tang in Chinese), traditional herbal medicines, on experimantal elevation of aqueous flare in pigmented rabbits. To produce the elevation of aqueous flare in rabbits, prostaglandin E2 (PGE2) was applied to the cornea with use of a glass cylinder, or lipopolysaccharides (LPS) were injected into the ear vein. Animals were pretreated by the oral administration of 150 g/day of food containing 0.7%, 0.2% or 0.07% (w/w) Orengedoku-to, or 2%, 0.6% or 0.2% (w/w) Senkanmeimoku-to for 5 days. Aqueous flare was measured with a laser flare-cell meter. Pretreatment with 0.7% or 0.2% Orengedoku-to and 2% Senkanmeimoku-to did suppress significantly (P < 0.05) elevation of aqueous flare induced by PGE2. Pretreatment with 0.7% or 0.2% Orengedoku-to and 2% or 0.6% Senkanmeimoku-to significantly suppressed (P < 0.001) elevation of aqueous flare induced by LPS. It is possible that Orengedoku-to and Senkanmeimoku-to may migrate some forms of uveitis.
