小児異所性尿管瘤に対して施行した後腹膜鏡下半腎摘出術の1例

5歳女児.1歳2ヵ月より尿路感染症を繰り返し, 右異所性尿管瘤と診断され保存的に経過観察されていた.IVP, DMSA腎シンチで瘤所属右上半腎は無機能で下半腎に国際分類III度の膀胱尿管逆流症を認めた.1998年8月13日, 右後腹膜鏡下半腎摘出術及び瘤切除, 右下半腎逆流防止術を施行した.術後経過は良好で, 術後3ヵ月目のVCGでも逆流は消失し, 腎機能も良好であった.小児における腹腔鏡下半腎摘出術は現在迄に15例の報告があるが, 後腹膜アプローチは本症例が初めてであるA 5-year-old girl with a history of recurrent urinary tract infection since the age of 14 months was diagnosed as having a right duplicated urinary collecting system with the upper ureter ectopically opening in the urethra. She underwent retroperitoneoscopic heminephrectomy for a right dysplastic kidney and open ureterocelectomy and reimplantation of the refluxing lower ureter via Pfannenstiel incision. She survived the procedure without serious complications and resumed normal daily activities by day 6. To the best of our knowledge, this case is the 16th case of laparoscopic heminephrectomy for pediatric patients and the first case treated by the retroperitoneal approach in the English literature

The aim of this study is to clarify the usefulness of PSA screening to detect prostate cancer subclinically in Tokushima City. Mass screening of serum PSA measurement only was started from ２００２ in Tokushima City. Three years’ results are reported and analyzed in this paper. In ２００２ to ２００４，（９０９９，９３４５，１０６８０） men over ５５ years old were measured serum PSA level with annual check of health condition at various outpatient clinics in Tokushima City. The men with high PSA levels were recommended to visit the urologist for further examinations. By the urologists the men with high PSA levels were diagnosed by careful urologic procedures including DRE, TRUS, accurate prostatic biopsy and more. In （８０１，６０６，７２７） men, PSA levels were over normal range, and （４５５，２５７，３５８） men visited urologic clinics for further examinations. Careful examinations were performed and prostatic biopsies were done in （２３３，１２１，１４１） men. Finally, the prostate cancers were found out in （１２１，６０，５９） men and these men were entered suitable medical treatments immediately. Accordingly， （１．３４％，０．６４％，０．５５％） of （９０９９，９３４５，１０６８０） men with PSA measurements were diagnosed as prostate cancers. In the group of prostate cancer, patient number of early cancer group （Stage B） were （８０：６６．１％，４２：７０．０％，５０：８４．７％），which means that prostate cancers found out by PSA screening might be early curable cancers in many cases. These ３ years’ results indicate that PSA screening is a very useful modality to find out early prostate cancers and contribute the decrease of prostate cancer death in Tokushima City in the future

Effects of low temperature treatment on plantlet growth and development of Asparagus officinalis L. in vitro (AGRICULTURE)

低温処理がアスパラガスの生長と発育に及ぼす影響を\u27Mary Washington 500W\u27を用いて調査した。一節をもつ外植体を0.05mg/l NAAと0.05mg/l BA含むMS培地で培養した。20℃で4週間培養後, 5℃で1,2,4,6,8週間培養した。処理の後は再び20℃で培養した。外植体が低温に1あるいは2週間処理された時, 植物の生長と発育は20℃に戻しても抑制された。外植体が低温に4週間処理されると, 生長と発育は20℃で回復した。4週間以上低温処理が続くと, 外植体の生長と発育は回復しなかった。The effects of low temperature on growth and development of asparagus were investigated using \u27Mary Washington 500W\u27 plantlets. The explants of single node were cultured on MS medium with the combination of 0.05mg/l NAA and 0.05mg/l BA. After the culture at 20℃ for 4 weeks, the explants were treated with the low temperature treatment of 5℃ for 1,2,4,6 or 8 weeks. After the treatment, they were cultured at 20℃ again. When asparagus plants were cultured at low temperature for 1 or 2 weeks, plantlet growth and development were suppressed even at 20℃. After they were cultured at 5℃ for 4 weeks, plantlet growth and development recovered at 20℃. Whenever the low temperature treatment continued longer than 4 weeks, the growth and development of plantlets did not recover

Morphological characteristics of wasabi (Wasabia japonica Matsumura) (AGRICULTURE)

ワサビ\u27だるま-3号\u27について形態的観察を行った。ワサビは日本など温帯アジア原産植物で, アブラナ科に属し, 宿根性である。通常葉と茎の基部が可食部として収穫される。可食部は通常根茎と呼ばれることが多いが, 肥厚して短縮化した茎である。肥厚した茎は地中で成育することが多い。葉柄の基部も肥厚している。いくつかの子株が茎の基部から伸張して, 繁殖に用いられる。花には4枚の白色の花弁, 6本の雄ずいと1本の雌ずいがある。Morphological characteristics of wasabi were investigated. Wasabi, which is originated in temperate Asian area such as Japan, belongs to crucifer and is perennial. Leaf and lower stem are usually harvested. An edible portion of wasabi, which is commonly stated as a rhizome is suitable to name a shortened and swollen stem. Swollen stem is grown usually underground. Bottom part of petiole is also swollen. Some offshoots are arising from basal nodes of stem and are used for propagation. There are four petals, six stamen and a pistil in the flower
