SAA1 and abortion: SAA1/2 alone (PBS+SAA1/2) did not induce abortion or PTB, i.e., no significant effect was observed compared with PBS+PBS (p > 0.05, Figure 2B and Table 1). Moreover, increased abortion was not observed in the LPS+SAA1/2 group compared with LPS+PBS (p > 0.05, Figure 2B and Table 1), implying that SAA1/2 at the presently studied dose was not sufficient to induce abortion or exacerbate LPS-induced abortion.
