| Objectives: The objective of this study is to determine the effects of Ethyl acetate fraction from Cudrania tricuspidata (EACT) on the interleukin-1b (IL-1b)-induced proliferation of rheumatoid synovial fbroblasts (RASFs) and production of matrix metalloproteinases (MMPs), cyclooxygenase (COX) and prostaglandin E2 (PGE2) by RASFs. Materials and Methods: The proliferation of RASFs was evaluated with CCK-8 reagent in the presence of IL-1b with/without EACT. The expression of MMPs, TIMP-1, COXs, PGE2 and intracellular MAPK signalings, including p-ERK, p-p38, p-JNK and NF-kB were examined by immunoblotting or semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) and ELISA in conditions as described above. Results: EACT inhibits... |

| The objective of this study was to evaluate the reproductive performance, liver morphological study and post mortem characteristics of the pregnant Wistar rats treated with indomethacin, a general COX inhibitor. Indomethacin at doses of 0 (control), 0.32, 1.68 and 8.40 mg/kg/day were orally given once daily to each group (n=10) on days 3 and 4 of pregnancy (day 0 = first day of pregnancy = positive vaginal sperm). The animals were euthanized under anesthesia on day 11 of pregnancy, and were carried out necropsy and microorganism culture study. The results showed that the doses of 0.32 and 1.68 mg/kg body weight (the therapeutic dose for humans) of indomethacin caused no embryotoxic or lethal effects. The highest dose (8.40 mg/kg) of indomethacin disturbed... |
