histamine
ヒスタミン
解説 Definition
histamine は体内で作られる化学物質で、アレルギー反応や炎症に関わるヒスタミンという意味です。日本語の「ヒスタミン」とほぼ同じ意味ですが、医学や生物学の文脈で使われる専門語です。
A biologically active chemical produced in the body that helps regulate immune responses, inflammation, stomach acid secretion, and certain nerve functions. Its release during an allergic reaction can cause symptoms such as itching, redness, and swelling.
覚え方のコツ Memory Tip
histidine「ヒスチジン」＋ amine「アミン」という化学的な成り立ちで覚える。体がアレルギー反応の際に histamine を release し、薬がその effect を block する場面を一組にするとよい。itching、swelling、allergic reaction と結び付きやすいが、ヒスタミン自体は体内で複数の働きをする化学伝達物質である。
Build the word from histidine and amine: histamine is an amine made in the body from the amino acid histidine. Remember it through a simple cause-and-control pair: during an allergic reaction, the body releases histamine; an antihistamine blocks or reduces its effects. Common partners include “release histamine,” “histamine levels,” and “the effects of histamine.” It is strongly associated with itching and swelling, but it is not merely an “allergy chemical.” It also functions in stomach acid secretion and signaling in the nervous system, so keep the broader biological role in mind.
例文

histamine の語源・成り立ち Etymology
histamine は histidine＋-amine からできた化学語で、さらに histidine はギリシャ語 histos「組織」にさかのぼります。つまり「組織に関わる成分由来のアミン」という名づけで、体内物質の名として納得しやすい語です。関連語は histology、amine。
Histamine is a scientific compound name formed from histidine and amine. The substance is produced biologically by removing the carboxyl group from the amino acid histidine. Histidine itself was named with reference to Greek histos, “tissue,” while amine identifies the compound’s nitrogen-containing chemical class. The name therefore reflects the substance’s chemical origin and structure rather than a symptom or disease, even though histamine is widely known for its role in allergic reactions.
