To study the effect of cholecystokinin-octapeptide (CCK-8) on systemic hypotension and cytokine production in serum and lung of endotoxic shock (ES) rats induced by lipopolysaccharide (LPS) and investigate its signal transduction mechanism of p38 mitogen-activated protein kinase (MAPK), the changes in mean arterial pressure (MAP) were observed by using a polygraph in four groups of SD rats: group of LPS (8 mg/kg i.v.) induced ES, group of CCK-8 (40 microg/kg i.v.) pretreatment 10 min before LPS (8 mg/kg) administration, group of CCK-8 (40 microg/kg i.v.) only, and normal saline (control) group; the contents of proinflammatory cytokines (TNF-alpha, IL-1 beta and IL-6) in the lung and serum were assayed using ELISA kits; and p38 MAPK was detected by Western blot. The results showed that CCK-8 alleviated LPS-induced decrease in MAP of rats; compared with the control, LPS elevated the levels of TNF-alpha, IL-1 beta and IL-6 in serum and lung significantly, while CCK-8 significantly inhibited the LPS-induced increases in TNF-alpha, IL-1 beta and IL-6 in serum and lung. The activation of p38 MAPK in the lung of ES rats was enhanced by CCK-8 pretreatment. These results suggest that CCK-8 can alleviate the LPS-induced decrease in MAP of ES rats and exert an inhibitory effect on the overproduction of proinflammatory cytokines, and that p38 MAPK may be involved in its signal transduction mechanisms.
