アレルギー

July 24, 1906 is the key date for アレルギー. The Austrian pediatrician Clemens Peter Freiherr von Pirquet published Allergie in Münchener Medizinische Wochenschrift, volume 53, pages 1457-58. The German form Allergie was built from Greek allos, other, and ergon, work or activity, and Duden also lists this Greek base. His definition covered altered reactivity after vaccination and serum therapy. Japanese borrowed アレルギー as a medical word in the Taisho and early Showa medical setting, 1912-1930s. Duden says Allergie first entered the Rechtschreibduden in 1929, and Japanese dictionaries mark the source as German Allergie. The term appears beside allergisch and Allergen in the original German discussion. It belongs with アレルゲン, 免疫, アナフィラキシー, and ツベルクリン反応 in the vocabulary of immune response and clinical diagnosis. In current Japanese, アレルギー means a medical hypersensitivity, and it also extends to mental rejection; 精選版日本国語大辞典 records that figurative sense with a 1970 example from Furui Yoshikichi's Tsumagomori. A compound such as 核アレルギー is closer to a strong policy aversion than a clinical allergy. A doctor may still prefer アレルギー反応 for the clinical process today.
