FIG. 7. Serum levels of pathogenic natural IgM antibodiesdecrease following murinehepatic ischemia and reperfusion. Serum levels of IgM antibodies against Annexin IV, PC,cardiolipin, and total IgM weremeasured by ELISA in micethat underwent IR. Sampleswere harvested at 6 hours postreperfusion. Data are presentedas fold change over sham.Mean 6 SEM, n 5 7-12; *P < 0.05.
