34歳,女性。頭痛に対して鎮痛薬を使用したところ口唇の腫脹を生じた。数ヶ月後に別の鎮痛薬を使用したところ,上下口唇と手背の水疱および手指の紅斑を生じ,色素沈着を残した。両薬剤に共通な成分であるアリルイソプロピルアセチル尿素 (Allylisopropylacetylurea,AIAU),イブプロフェン,無水カフェインのいずれかによる固定薬疹を疑い,これらの成分に対して無疹部でのクローズドパッチテストを行ったがすべて陰性であった。そのため上下口唇の色素沈着部に AIAU とイブプロフェンをそれぞれ20%含有するワセリンを単純塗布すると,5分後に紅斑が出現した。また無水カフェインの口唇色素沈着部への,AIAU の手背色素沈着部への単純塗布はそれぞれ陰性であった。本症例は皮膚粘膜移行部の固定薬疹であり,同部でのオープンパッチテストは結果が早く得られ,安全で有用性の高い検査法であった。(皮膚の科学,12: 26-30, 2013)

1. Several morphologicai and physiological characters of triploid varieties were compared with diploids. 2. There was no clear difference on the leaf size and shape between triploids and diploids, but triploid leaves were thicker than those of diploids. As a rule every internal tissue of triploid leaves was thicker than diploids. It is evident that triploid leaves had larger stomatas of which the distribution density vias lower, compared with diploids. 3. No difference between both the plants could be recognized on the res.istance to brown blight total nitrogen and tannin content in suminer, the reduced form vitamin C content in winter, and regeneration power in cutting. Triploid varieties was more hardy to cold, and some of them had extremely early growing spring bud. The water reserving ability of triploid leaves isolated from stem was greater than that of diploids in September, but the relation changed to be indifferent. in December. 4. Generally triploid fertility was very low but the difference of fertility between each triploid variety was noticed. The pollen grains of triploids showed high sterility. 5. From progenies of triploids, we discovered one aneuploid plant (2n=44). The characters were same like those of triploids and the meio. sis was proceeded abnormally. 6. With colchicine treatment to the growing point of germinated seeds, some tetraploid plants (2ri=60) were obtained. At present, tetraploid plants are growing slowly and they have, dwarf form.
