It also resulted in theactivation of macrophages and the infiltration of neutrophils becauseof an increase in clusters of differentiation 68 (CD68)- and granulocyte-differentiationantigen-1 (Gr-1)-positive cells compared with the control group, whilethese changes were reversed in LPS-induced ALI mice after WED (5,10, and 20 mg/kg) treatment. Here, CD68 is linked to acute respiratory distress syndrome.
