慢性副鼻腔炎と精神機能（第2報）—中学生の精神作業に及ぼす影響

　前報に於て我々は，本症と中学生の基本的智能との間に或種の関連性の存在する事を報告したが本報に於ては，同一被検者を使用し，一定の精神作業を為さしめた際，本症罹患児と対照健康児とが示す作業態度との間に如何なる差異があるかに就いて検討して見ようと思う．

　我々の日常生活には，一定の目的の下に出来るだけの成果を収めようとして行う精神活動が仲々多いが，この樣なものを精神作業と呼ぶ．精神作業が人間の智的活動を土台とする以上，之れと前報に於いて述べた智能との間に密接な関係のある事は否定出来ぬが，作業中には智能と直接関係のない種々の因子が働き，作業機能が一つの動搖を為しつつ消長する．従つて本症の如く精神的機能と密接な関連ありと考えられる疾患は，この樣な実際的精神活動の面でも何等かの影響を被検者に及ぼすのではないかと疑われる．そこで我々はKraepelin内田氏精神作業検査法を採用し，本命題の検索を行つて見たのである．

SUZUKI AND HIRABAYASHI find a definite lowering in accomplishment of mental work which was perfurmed, in accordance to Kraeplin-Uchida test, by a group of individuals affected with chro-nic sinusitis. The comparison was made among the Third Year High School students who were divided into two groups, the one of which composdd of 43 individuals who were affected with chronic sinusi-tis and, the other, 125 who were considered to be normal in health. A marked difference in accomp-lishment of the two groups was noted when the w-ork was resumed after period of test which follow-ed the previous session. It was also noted that in-dividuals in the affected group tired far more easily and recovered slowly than those in the normal.
