患者は71歳, 男性. 発熱, 全身倦怠感を主訴として近医受診. CTにて肝に多発性結節性病変を認められ, 精査加療目的に当科紹介入院となった. 血管造影にて肝臓に多発性小動脈瘤を認め, 病理学的所見と合わせ結節性多発動脈炎と診断した. HBVキャリアであったため, 治療として免疫抑制作用が比較的少ないメソトレキセートを使用した. 治療後炎症所見は消失し, また血管造影にて認められた動脈瘤も消失した.

Gas chromatographic determination of new fungicidal cycloimides, Dichlozoline and Dimetachlone

BUNSEKI KAGAKU (1971)

Atsushi MURANO Tadashi Doi Masayuki Nagase

新環状イミド系殺菌剤3-(3', 5'-ジクロルフエニル)-5,5-ジメチルオキサゾリジン-2, 4-ジオン(ジクロゾリン)およびN-(3, 5-ジクロルフェニル)コハク酸イミド(ジメタクロン)は,水素炎イオン化型検出器を装着したガスクロマトグラフ(GC)を用いて,良好なクロマトグラムを得ることができ,かつ,不純物との分離もよかったので,内部標準法による定量を試み,それぞれについて,正確に精度よく分析できる方法を確立した.ジメタクロン中の不純物N-(3, 5-ジクロルフェニル)コハク酸モノアミドはGC操作中に溶出せず,一部分閉環してジメタクロンに変化するが,含有量が10%以下ではジメタクロンの定量値に影響なく,GC操作前に除去する必要はなかった.製剤中のジクロゾリンおよびジメタクロンは,クロロホルムで抽出したのち,原体の方法に準じて分析できた.

[Three cases of multiple liver metastases of carcinoid tumor responding to hepatic arterial infusion chemotherapy using degradable starch microspheres].

PubMed (2002)

Kunihiro Takanashi Hisato Homma Shinichi Mezawa Tadashi Doi Takehide Akiyama

We describe three patients with multiple liver metastases of carcinoid tumor who received hepatic arterial infusion chemotherapy using degradable starch microspheres (DSM). A partial response was obtained in all cases, and no side effects were observed. We believe that this chemotherapy was an effective treatment for unresectable liver metastases of carcinoid tumor.

Determination of allethrin and other pesticides in mosquito coils by the shaking extraction method.

Agricultural and Biological Chemistry (1985)

Shigeyuki Sakaue Tamotsu Doi Tadashi Doi

A method for the determination of allethrin and other pesticides in mosquito coils was developed by the combination of shaking extraction and gas chromatography (GC). Allethrin and other pesticides were adequately extracted by shaking for only half an hour with a mixture of toluene and 99% formic acid (5:1). This shaking extraction method was more effective for shortening the extraction time compared with the Soxhlet extraction method, and accurate determination was achieved without the interference from inert materials in the mosquito coils. The recovery of allethrin in various contents from the coils was 96.6 to 97.1%, with a 1.2 to 1.5% coefficient of variation. Furthermore, the recoveries of other pesticides and synergists from the coils were 94 to 102% by this shaking extraction method.

MRSA on the Otolaryngological Ward.

Practica Oto-Rhino-Laryngologica (1993)

Shugo Shiraishi Tadashi Iwano Kaoru Kawasaki Tadashi Doi Koichi Ushiro

A clinical and statistical study of methicillin-resistant Staphylococcus aureus (MRSA) was conducted on 27 patients with malignany tumor who had been on the ward for over 2 months and 27 medical personnel on the otolaryngological ward. Seven of the 27 patients (25.9%) had MRSA in the oralcavity and 2 of the medical personnel (7.4%) in the nasal cavity. Two background factors seem to be correlated to the colonization of MRSA. The reduced local host defense in the oral cavity after surgical or radiation therapy and the application of third generation cephalosporins. These patients with MRSA in the oral cavity were treated with iodine mouth wash 6 times a day for 14 days, but no reduction of MRSA was observed.

Postnatal Development of Thiamine Metabolism in Rat Brain

Journal of Neurochemistry (1989)

Toshio Matsuda Tadashi Doi Hideo Tonomura Akemichi Baba Heitaroh Iwata

Abstract: The activities of thiamine diphosphatase (TDPase), thiamine triphosphatase (TTPase), and thiamine pyrophosphokinase and the contents of thiamine and its phosphate esters were determined in rat brain cortex, cerebellum, and liver from birth to adulthood. Microsomal TTPase activity in the cerebral cortex and cerebellum increased from birth to 3 weeks, whereas that in the liver did not change during postnatal development. Microsomal TDPase activity in the cerebral cortex showed a transient increase at 1–2 weeks, but that in the cerebellum did not change during development. In contrast to the activity of the brain enzyme, that of liver microsomal TDPase increased stepwise after birth. Thiamine pyrophosphokinase activity in the cerebellum increased from birth to 3 weeks and then decreased, whereas that in the cerebral cortex and liver showed less change during development. TDP and thiamine monophosphate (TMP) levels increased after birth and plateaued at 3 weeks whereas TTP and thiamine levels showed little change during development in the cerebral cortex and cerebellum. The contents of thiamine and its phosphate esters in the liver showed more complicated changes during development. It is concluded that thiamine metabolism in the brain changes during postnatal development in a different way from that in the liver and that the development of thiamine metabolism differs among brain regions.
