To explore the inhibition of juglone in Qinglongyi on A-549 cells in vitro, MTT assay was used. Laser confocal scanning microscope was used to observe apoptotic morphology. Changes of cell cycle are studied by flow cytometry analysis. The result of MTT assay showed that juglone had a marked growth inhibition in A-549 cells and the IC50 is respectively 3.4 × 10-5 mol/L, 1.8 × 10-5 mol/L and 2.6 × 10...
In this issue, the effect of toluene diisocyanate on the mice blood secrum was studied to discuss its mechanism of EOS infiltration and conglomeration, which was the emblematical character of vocational asthma. Effects of TDI on the mass concentrations of IL-4, IL-5 in mice serum and granulocyte-macrophage colony-stimulating factor was observed by double-antibody sandwich enzyme-linked immunosorbent...
In this paper, the domestication of the activated sludge by which nitrobenzene can be degraded in a relatively poor nutrition is studied. The ability of activated sludge degradation of nitrobenzene is studied by degradation kinetics. The toxicology validation about the effect of activated sludge degradation of nitrobenzene is preliminarily explored. The results show that: The nitrobenzene could be...
Using terahertz time-domain spectroscopy (THz-TDS), we have measured the absorption spectra of alpha-hydroquinone and methane- and methanol-loaded beta-hydroquinone clathrates up to 3 THz frequency range. The alpha-hydroquinone exhibits 11 resonances whereas methane- and methanol-loaded beta-hydroquinone clathrates show only 1 resonance. The observed THz resonances represent the intermolecular and...
The mechanism and effect of the PH, drug solution concentration, intestinal segments, P-gp on Cinnamic acid absorption in rat's intestine were investigated by using in situ single-pass perfusion technique in rats. Results showed that the absorbed dose of Cinnamic acid was increased linearly and no saturation of high concentration was observed when drug concentration was in rang of 0.02-0.10 mgmiddotml...
