説明
Recently, prostacyclin (PGI2) has been used for the treatment of preeclampsia. In this study, we investigated the effects of PGI2 on placental blood flow (measured with clearance of hydrogen gas generated by electrolysis) in normotensive Wistar Kyoto rats (WKY) and spontaneously hypertensive rats (SHR). The placental blood flow of PGI2-treated SHR (0.25, 0.5 and 1 mg/kg) was significantly (p less than 0.05) reduced compared with WKY. These data suggest that PGI2 has a certain reducing effect on placental blood flow in SHR; on the other hand, in WKY, it has an increasing effect depending on the dose.
