Near-infrared red spectroscopy (NIRS) is a noninvasive method that uses changes in cerebral blood volume (CBV) to measure relative changes in tissue concentration of oxygenated, deoxygenated and total hemoglobin. We used this technique to determine the cortical activation area during Japanese grammatical processing. To assess the relative changes in total hemoglobin, local changes in near-infrared absorption were measured simultaneously from seven points in both hemispheres. Nine subjects were presented target stimuli, and were asked to decide whether the attendant particle was “ga” or “wo” in Japanese grammatical tasks (experimental conditions), and whether the relative position was “front” or “back” in positioning tasks (baseline and control conditions). To control subvocal rehearsal and conceptual driven processing, the same Kanji character was presented visually as a target in the experimental and control conditions. Total hemoglobin increased in Broca's area when subjects made judgments in Japanese grammatical tasks, compared to positioning tasks. These results suggested that the task of deciding particles in Japanese grammatical processing might be an effective and objective method to assess language disorders.

年齢層別化アンチバイオグラムの意義について検討を行った.2015年4月からの1年間に当院にて分離頻度が高かった黄色ブドウ球菌,肺炎球菌,インフルエンザ桿菌,大腸菌,緑膿菌を対象に,抗菌薬感性率を小児,非高齢成人,高齢成人で比較した.グラム陽性菌では,成人由来株との比較において小児由来のメチシリン感性黄色ブドウ球菌ではマクロライド低感受性,メチシリン耐性黄色ブドウ球菌ではレボフロキサシン(LVFX)およびミノサイクリンの高感受性が示され,肺炎球菌では髄膜炎基準で小児由来株のペニシリン低感受性が示された.非高齢成人と高齢成人では差はみられなかった.グラム陰性菌では,小児および高齢成人が非高齢成人よりも比較的感受性が低かった.特に大腸菌ではアンピシリン/スルバクタム,セフェム系抗菌薬,LVFX,ST合剤,ホスホマイシンの多系統の低感受性が認められた.臨床上問題となる耐性菌の分離率は非高齢成人が最も低く,小児および高齢成人における初期治療において注意が必要と考えられた.年齢層別化アンチバイオグラムの作成は特に小児,高齢成人の感染症の初期治療において重要と考えられた.

We examined whether the effective visual field to identify target figure would be enlarged by the prime stimulus, which is presented at the central field of view. The target was presented from 1.00 to 9.25deg. of horizontal eccentricity. In experiments I and II, we varied the type of information given just prior to presentation of a geometric target figure, and we analyzed the reaction time and percent of correct responses to identify target under several conditions. By experiment I, it was found that direct prime information in the form of the target figure itself (Match condition) provided more spatial and temporal effects at the non-Match condition. Experiment II showed that semantic prime information in the form of figure's name by characters was also most effective than other conditions, but it was only for temporal aspect.
