衛生管理を施した太巻き寿司に衛生基準を下回る量ではあるが大腸菌群が検出されたことに着目し,その原因食品を把握するためその素材の付着菌数について検討した。1.一般細菌は各素材から検出され,海苔(平均1.9×10^3個/g),桜でんぶ(平均1.8×10^3個/g),野沢菜漬(平均6.4×10^2個/g),山ごぼう(平均1.1×10^2個/g),紅生姜(平均1.5×10^1個/g),卵焼き・寿司飯(平均1.0×10^0個/g)の順に多かった。2.大腸菌群は野沢菜漬の10試料中5試料から平均2.0×10^2個/g検出されたが,他の素材からは全く検出されなかった。3.販売形態別に付着細菌をみると,「量り売り」,「袋入り(工場詰め)」のいずれからも細菌が検出され,5.0×10^1個/g以上の一般細菌の検出率は,「量り売り」では90%,「袋入り(工場詰め)」では50%であった。以上のことから,使用に当たっては洗浄や加熱による細菌の付着抑制を行う等の対応が考えられる。

We have experienced 6 patients with the psychogenic hearing impairment in the past 6 months. They were all female and their age ranged from 11 to 13 years. Hearing impairment was bilateral in 5 patients and was unilateral in one. To establish the diagnosis, standard audiometry, speech audiometry Bekesy audiometry, Evoked Response Audiometry (Auditory Brainstem Response and Slow Vertex Response), stapedius reflex test, and tympanometry were performed. The visual field test was also examined and the personality of the patients was tested using Yatabe-Guilford test. The pure tone test revealed that the degree of hearing loss ranged from 40 dB to out of scale. The degree of hearing loss obtained by the speech audiometry was better than that was obtained by the pure tone test. Bekesy audiometry in 11 ears showed type V in 5 and type I in 6. The tympanogram, ERA (ABR and SVR), stapedius reflex were normal in all patients. In two patients, the defect of the visual field was observed. The results of the tests to study the personality of the patients revealed various types of abnormalities. This abnormalities were thought to be the intrinsic factors in this disease. In 5 patients, we found the extrinsic factors in their daily lives. The prognosis of 5 out of the 6 patients was good, but in 1 patient, whose charactor showed to be in a high grade neurotic state, the hearing loss was not changed. We treated her with the co-operation of a psychiatrist.
