Objectives : The purpose of this study was to investigate the anti-cancer effects of Oldenlandia diffusa extract on WiDr human colorectal adenocarcinoma cells. Methods : We examined cell death by (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) MTT assay and the caspase 3 and 9 activity assay with Oldenlandia diffusa extract. To examine the inhibitory effects of Oldenlandia diffusa extract, we performed a cell cycle (sub-G1) analysis and mitochondrial membrane potential for the WiDr cells after 24 hours with Oldenlandia diffusa extract. Results : 1. Oldenlandia diffusa extract induced cell death in WiDr cells. 2. The sub-G1 peak was increased by Oldenlandia diffusa extract in WiDr cells. 3. Oldenlandia diffusa extract leads to increase the mitochondrial membrane depolarization in WiDr cells. 4. Oldenlandia diffusa extract increases caspase 3 and 9 activities in WiDr cells. 5. Oldenlandia diffusa extract combined with several anti-cancer drugs (paclitaxel, 5-fluorouracil, cisplatin, ectoposide, doxorubicin and docetaxel) markedly inhibited the growth of WiDr cells compared to Oldenlandia diffusa extract and anti-cancer drugs alone. Conclusions : Oldenlandia diffusa extract has an apoptotic role in human colorectal cancer cells and a potential role in developing therapeutic agents against colorectal cancer.

Objectives: The purpose of this study was to investigate the effects of Shengmai-san and Pyungwi-san, a herbal product used in traditional Chinese medicine, on gastrointestinal (GI) motility in mice. Methods: The in vivo effects of Shengmai-san and Pyungwi-san on GI motility were investigated by measuring the intestinal transit rates (ITRs) using Evans blue in normal mice and in mice with experimentally induced GI motility dysfunction (GMD). GMD was induced by injecting acetic acid or streptozotocin intraperitoneally. Results: In normal Institute of Cancer Research mice, ITRs were significantly and dosedependentlyincreased by Shengmaisan (0.01∼1 g/kg) and Pyungwi-san (0.01∼1 g/kg). The ITRs of acetic acid induced peritoneal irritation model and streptozotocin-induced diabetic model mice were significantly reduced compared to normal mice, and these reductions were significantly and dose-dependently inhibited by Shengmai-san (0.01∼1g/kg) and Pyungwi-san (0.01∼1g/kg). Conclusions: These results suggest that both Shengmai-san and Pyungwi-san are a good candidate for the development of a prokinetic agent that may prevent or alleviate GMD.
