reperfusion
再灌流
解説 Definition
医学用語で、血流が一度途絶えた部分に再び血液が流れることを指します。特に心臓の治療で重要な概念です。
Reperfusion is the return of blood flow to a part of the body after it was blocked or reduced. It is a medical term often used when doctors treat a heart attack, stroke, or injured tissue. The word can also refer to the effects that happen when blood flow comes back.
覚え方のコツ Memory Tip
re- は「再び」なので、まず「もう一度」の感覚を置くと入りやすい語です。さらに infusion（点滴で注入）, transfusion（輸血）を知っていれば、-fusion 系は「液体を流し込む・通す」医学語だとまとまります。そこで reperfusion は「血流を再び通すこと」＝再灌流。心筋梗塞では restore blood flow の文脈で出やすく、reperfusion therapy や reperfusion injury まで一緒に覚えると定着します。refusion と見誤らず、中心語は perfusion です。
Notice the parts: `re-` means "again," and `perfusion` is a medical word about fluid flowing through tissue. So `reperfusion` is about flow coming back again. It often appears with `reperfusion therapy` and `reperfusion injury`, so learn those phrases together.

reperfusion の語源・成り立ち Etymology
reperfusion は re-「再び」+ perfusion から成り、後者はラテン語 perfusio、さらに per-「通して」+ fundere「注ぐ」に由来します。つまり「再び流し込むこと」で、止まっていた血流を戻す医学語だと分かります。関連語は perfuse, transfusion。
Reperfusion is formed from re- "again" and perfusion. Perfusion comes from Latin perfusio, from per- "through" and fundere "to pour." The original image is of liquid being poured through something, and in medical English it developed into the idea of blood flowing through tissue again. Related words include perfuse and transfusion.
