Changes in plasma levels of total PS and free PS in LPS-treated rats. Citrated plasma was obtained from three rats treated with LPS intraperitoneally (2 mg · kg−1) at each time point to determine (a) plasma total PS antigen levels and (b) plasma free PS antigen levels, as described previously in [31]. Data are expressed as the mean ± S.D. (n = 3). *P < .05 versus time 0.
