Cao and coworkers reported that the synthesized Co/PMCS could significantly reduce the number of bacteria in the liver, lung, kidney, intestines, and blood of E. coli-induced bacteremia in mice, as well as reducing the white blood cells (WBC), ROS, alanine transaminase (ALT), RNS, IL-6, TNF-α, Lym, Neu, and urea, in organs and blood, when compared with those of the PBS-treated control group. Here, IL6 is linked to bacterial infectious disease with sepsis.
