科普專欄–薯不揀單 - 三十秒科學–預測產嬰日

新生命的誕生固然是開心的事情，但若能更準確預測或計算出產嬰日子，那就更加完美!483Please respect copyright.ＰＥＮＡＮＡmSKeGfGzXY

現時的預產期是由最後月經之日加上40星期作計算，再加以從超聲波檢查時所得的影像再作調整預算日子。483Please respect copyright.ＰＥＮＡＮＡCD74ZKvJSS
奈何，很多時候產嬰之日並非真的是準確地落在40星期領域之內，預算日子總是與真實日子有所出入。483Please respect copyright.ＰＥＮＡＮＡMinAtblXrK

(圖2)有研究找來53名懷孕女士，檢驗她們誕嬰前100日每一日的血液成份，並將內有的各成份分門別類，希望可以找出那一些物質的轉變會有著誕嬰的顯示。483Please respect copyright.ＰＥＮＡＮＡMxCa7yAH0P

(圖3)研究得出不少物質均有著估算產嬰日子的價值，其中激素17-Hydroxyprogesterone在誕嬰前30日會有著急劇上升的跡象，而負責控制血管新生的sTie-2及抑制血液凝固的antithrombin III在試嬰前30日則有著下降的趨勢。483Please respect copyright.ＰＥＮＡＮＡmtmyA5GRFX

他日若能獲得更多數據的話，分分中能夠將準確預測的日期更為收窄，讓醫院、孕婦及老公各方有著更好的準備。483Please respect copyright.ＰＥＮＡＮＡBNS2rubXwG
