Artesunate (ART), derived from a common traditional Chinese medicine, has beeen used an antimalarial for several years. In this study, the effect and mechanism of ART on anti-human cervical cancer cells was examined. The level of prostaglandin E2 (PGE2 ) and the population of CD4+CD25+Foxp3 regulatory T cells (Treg) in peripheral blood were detected by flow(More)
The aim of this study was to observe the influence of gap junction (GJ) functional changes on the hepatotoxicity of TNF-α. Three different methods were employed to study functional effects of the GJ inhibition: 1) pretreatment with a GJ inhibitor; 2) inoculation of cells at high and low densities; and 3) inhibition of the expression of connexin 32 (Cx32) by(More)
The splenic sinuses, lymphocytes and antigen presenting cells in the spleen of rat stimulated by He-Ne laser acupuncture were observed by using TEM to investigate the ultrastructural changes of them. The width of endothelial interstice was increased, hence a lot of blood cells oozed out of the splenic sinuses. There were numerous activated T cells which(More)
The lymphocytes and antigen presenting cells in lymph node of rats stimulated by He-Ne laser acupuncture were observed by using TEM and SEM to investigate the ultrastructural changes of them. There were numerous activated T-cells which showed deeply indented nucleus, abundant small void mitochondria and free ribosomes in the paracortex area. The B-cells(More)
