Evodia rutaecarpa (E. rutaecarpa) has been used to treat aches, vomiting and dysentery in traditional Chinese medicine. However, as a mildly toxic herb its toxic components have not been elucidated. An attempt was made to illuminate the hepatotoxic constituents of E. rutaecarpa. The 50% ethanol extracts of E. rutaecarpa from 19 different sources were used(More)
We report the design and test results of a beam monitor developed for online monitoring in hadron therapy. The beam monitor uses eight silicon pixel sensors, Topmetal-II−, as the anode array. Topmetal-II− is a charge sensor designed in a CMOS 0.35 μm technology. Each Topmetal-II− sensor has 72 × 72 pixels and the pixel size is 83 × 83 μm. In our design, the(More)
Compared with chemical drugs, it is a huge challenge to identify active ingredients of multicomponent traditional Chinese medicine (TCM). For most TCMs, metabolism investigation of absorbed constituents is a feasible way to clarify the active material basis. Although Andrographis paniculata (AP) has been extensively researched by domestic and foreign(More)
OBJECTIVE To investigate the absorption of gnsenoside Rg1 and Rb1 in Radix Gngseng at different intestine segments of rats and the influence of the drug solution concentration, pH, P-gp inhibitor. METHOD The intestine cannulation was performed for in situ recirculation. Gnsenoside Rg1, Rb1 and phenol red concentration in the flux were separately measured(More)
