CONJUGATED ECDYSONE IN THE EGGS OF THE SILKWORM, BOMBYX MORI

Development Growth & Differentiation (1975)

Takashi Mizuno Eiji Ohnishi

A high activity of molting hormone (ecdysone) was detected in the extract of unfertilized, diapausing and developing silkworm eggs. The active substance in the diapause eggs behaved as a highly polar molecule at partitioning between n-butanol and water, and also in TLC. The majority of the activity seems to be due to a conjugated ecdysone, since the polar active substance was changed to a less polar substance upon treatment with "snail enzymes".

A case of spontaneous hemopneumothorax treated by transcatheter arterial embolization and thoracoscopic surgery

Nihon Kyukyu Igakukai Zasshi Journal of Japanese Association for Acute Medicine (2014)

血管塞栓術が有効であった自然血気胸の1例を経験した。症例は20歳の女性で，誘因なく右背部痛を自覚した。呼吸苦・疼痛が増強し，近医を受診して当院救急外来を紹介となり，転院搬送となった。胸部X線検査で右胸腔内の貯留液と肺の虚脱を認め，CTで縦隔のシフトを伴っていた。胸腔ドレーンを挿入すると約700mLの血性の排液を認め，自然血気胸と診断した。持続する出血を認め，翌日当科紹介となったが，バイタルサインが比較的安定していたこともあり血管撮影を施行した。右気管支動脈造影を行うと気管支動脈から第2・3肋間動脈が分岐しており，この末梢に異常血管を認めたため，n-butyl-2-cyanoacrylateで塞栓を行った。以後胸腔ドレーンからの血性排液は停止したものの，胸腔内に残留した血腫の除去に難渋し，塞栓術の3日後に胸腔鏡下血腫除去を行った。術中血腫以外に新たな出血は認めなかった。肺尖部付近の肋骨下縁から連続する索状構造がみられ異常血管と考えられた。右肺は全体に凝血塊に被われていたが，良好な視野のもと掻破・吸引により約400mLの血腫を除去した。術後経過は良好で第8病日に退院となり，以後血気胸の再発は認めていない。自然血気胸は出血量が2,000mL以上に及んでショック症状を呈し，早急な対応が必要となる場合がある。本疾患に対する経カテーテル的動脈塞栓術は，ショックを認めない症例や胸腔鏡下手術のhigh risk症例などに対して治療の選択肢の一つになりうると考えられた。

A Case of Rectal Gist Performed Sphincter Saving Operation by Cluneal Arched Skin Incision

The Japanese Journal of Gastroenterological Surgery (2010)

Jiro NAGATA Sho Hirabayashi Eiji Ohnishi Kenichi Nakanishi Hisaharu Ohya

症例は76歳の男性で，肛門管にかかる下部直腸原発の粘膜下腫瘍gastrointestinal stromal tumor（以下，GIST）の診断で手術を行った．Jack-Knife位で臀部を弧状に切開して直腸に到達し，腫瘤を含めて直腸後壁を切除して縫合閉鎖した．予防的に造設した人工肛門は6週間後に閉鎖した．腫瘍の大きさは6.5×4.8×4.0 cmで，病理組織学的に直腸原発のuncommitted typeのGISTと診断された．排便機能は良好に保たれており，術後2年の現在，再発徴候なく外来で経過観察中である．直腸原発GISTに対する後方からの臀部弧状切開によるアプローチは，従来の後方アプローチによる術式に比べて創感染を含めた術後合併症の発生を軽減できる可能性があり，また術野が良好で直視下にsafety marginを確保しながら切除しうることから根治性の面でも満足できる術式であると考えられた．この症例につき文献的に考察を加えて報告する．

Surgical treatment for rectal cancer with abnormally expanded inferior mesenteric vein resulting from pancreatic arteriovenous malformations

Surgical Case Reports (2015)

Hiroshi Tanabe Tsunenobu Takase Takahiro Inaishi Mariko Masubuchi Naohiro Nomura

A 52-year-old Japanese man presented for evaluation and treatment of rectal cancer. Screening computed tomography revealed pancreatic arteriovenous malformations (P-AVMs) and abnormally expanded inferior mesenteric vein (IMV) that resulted from P-AVMs. One-stage surgery for rectal cancer was dangerous so we first performed distal pancreatectomy to cure P-AVM and thus normalize the abnormally expanded IMV. After the operation, the IMV was occluded by the thrombi, and then the IMV became normal. We could perform safely radical laparoscopic surgery for rectal cancer. This is the first case report of P-AVMs combined with rectal cancer.
