摘要：

A sensitive enzyme-linked immunosorbent assay (ELISA) for rat interleukin 8/cytokine-induced neutrophil chemoattractant (CINC) has been established by using biotin-conjugated anti-CINC rabbit IgG. The biotin-streptavidin sandwich ELISA detected CINC at concentrations from 3 pg/ml up to 30 ng/ml. The concentration of CINC in the pouch fluid (exudate) of rat carrageenin-induced inflammation was measured by the ELISA. After a time lag of about 2 h, neutrophils steadily accumulated in the carrageenin/air-pouch until 8 h. Similarly, the CINC level of exudate increased after about a 2-h lag, and reached a maximum (134 ng/ml) at 8 h, and thereafter decreased to a negligible concentration at 24 h after carrageenin injection. In association with the rise in CINC level, the concentration of exudate 96-kDa gelatinase corresponding to neutrophil gelatinase/type IV collagenase increased with time. The results suggest that CINC contributes, at least in part, to the neutrophil migration into the inflammatory lesion of the carrageenin-induced inflammation in rats.
