Pollen allergens

Japanese: 花粉アレルゲン - かふんあれるげん
Pollen allergens

…It is a compound word of the Greek words allos (different, changed) and ergon (action, ability), and was first used by Austrian pediatrician Clemens F. von Pirquet (1874-1929) in his paper Allergy, published in 1906. It means "changed reaction ability" or "mutagenic action," and refers to a case in which a living body that comes into contact with a foreign substance shows a different reaction to the substance than before. For example, this corresponds to a case in which a person becomes hypersensitive to the drug after receiving a penicillin injection and dies of shock from the injection (penicillin shock), or a case in which hives occur after eating fish or eggs. …
