Luminol chemiluminescence in phorbolester-activated cultured rat liver Kupffer cells was strongly inhibited by the selenoorganic compound ebselen (IC50 = 2 mumol/L). Ebselen (2-phenyl-1,2-benzisoselenazol-3[2H]one) also diminished reduction of ferricytochrome c (IC50 = 10 mumol/L), indicating a supp

โฆ Synopsis
An aqueous extract of Tinospora tuberculata stems was found to scavenge nitric oxide (NO) in vitro in both cell and cell-free systems. When the aqueous extract was added to lipopolysaccharide-stimulated murine macrophages, it inhibited NO release dose-dependently, and similar activity was found in a cell-free system using sodium nitroprusside as a NO donor. These findings may help to explain, in part, certain pharmacological activities of Tinospora tuberculata.

This study was designed to determine the effector molecule responsible for the tumor-inhibitory activity of rat neutrophils treated with rat recombinant interferon gamma (rIFN-gamma) in vitro. The results show that nitric oxide (NO) production by neutrophils is dependent on rIFN-gamma concentration,
