In this study, we extracted a polysaccharide (short-chain polysaccharide [PS]) from porcine cartilage and examined its function in chronic myeloid leukaemia by using human K562 cells and mouse L1210 cells. Results of cell proliferation assay indicated that PS inhibited cancer cell growth at different concentrations, while it had little effect on normal(More)
TiSiN nanocomposite Alms have been deposited on YT15 cemented carbide by a cathodic arc plasma plating system. Structure, mechanical and tribological properties were investigated by X-ray diffraction, Scanning electron microscope, tribometry, Profiler and Vickers indentation techniques, systemically. The results show that TiSiN films are the typical(More)
A method for the determination of geniposide in Fructus Gardeniae was established by HPLC. HPLC conditions: column: TSK GEL LS-410, mobile phase: 0.05 mol/L Na2 HPO4-MeOH (80:20) (pH = 6.86). Quantitative determination was made using peak area. Samples of various parts of the plant and of different habitats together with their pharmaceutical preparations(More)
