[Effects of Liangxue Tongyu Formula on brain edema and expressions of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 in rats with intracerebral hemorrhage].

Objective: To investigate the effects of Liangxue Tongyu Formula (LXTYF), a compound traditional Chinese herbal medicine, on brain edema in rats with intracerebral hemorrhage and to explore the mechanism.

Methods: Intracerebral hemorrhage was induced by using the intrastriatal autologous blood injection. Rats were randomized into sham-operated (SO) group, intracerebral hemorrhage (ICH) group and LXTYF group.

Aqueous extract of Yin-Chen-Hao decoction, a traditional Chinese prescription, exerts protective effects on concanavalin A-induced hepatitis in mice through inhibition of NF-kappaB.

In traditional oriental medicine, Yin-Chen-Hao decoction is used for the remedy of liver diseases such as hepatitis, fatty liver, hepatocirrhosis and jaundice. However, despite extensive pharmacological study, the molecular mechanism of the anti-inflammatory effect of Yin-Chen-Hao decoction is poorly understood. In this study, we have investigated the pharmacological action on the mechanism of concanavalin A-induced T cell-dependent hepatitis in mice.
