| Outline of Final Research Achievements |
The pathophysiology of amniotic fluid embolism is thought to be anaphylactoid-like (anaphylactoid) reaction caused by inflow of amniotic fluid into the maternal circulation, but it has not been experimentally verified. In this study, we examined the effect of amniotic fluid intravenous administration on the blood components of pregnant rats, and the influence of amniotic fluid exposure on mast cells, the main constituent of anaphylactic reaction. As a result, no significant fluctuation of were observed in anaphylatoxin (C3a, C5a) and C1 inhibitor in pregnant rats administered amniotic fluid. In addition,cultured mast cells exposed to amniotic fluid did not induced degranulation. On the other hand, D-dimer increased significantly in the amniotic fluid administration group, suggesting that thrombus formation occurs by intravenous injection of amniotic fluid. Therefore, it was suggested that amniotic fluid affected blood coagulation function.
