    Abstract:
    The present study was performed to investigate the anti-septic effects of Qi-Shao-Shuang-Gan (QSSG), a combination of Astragalus membranaceus saponins (SAM) and Paeonia lactiflora glycosides (GPL), in septic mice induced by cecal ligation and puncture. QSSG was shown to elevate the survival rate of mice, decrease infiltration of polymorphonuclear leukocytes into livers and lungs, lower serum levels of myeloperoxidase, nitric oxide, and lactate dehydrogenase, and decrease mRNA expressions of inducible nitric oxide synthase and interleukin-1β in livers. It also restored the impaired expressions of protein C (PC) mRNA in mouse livers and expressions of thrombomodulin and endothelial PC receptor mRNA in endothelial cells. Neither SAM nor GPL alone could significantly increase the survival rate of septic mice. The findings indicate that QSSG exerts protective action against polymicrobial sepsis by inhibiting systemic inflammatory response and upregulating PC pathway, and there are synergistic effects between SAM and GPL.
