古尔班通古特沙漠人工林土壤水分及其影响因素

通过2004年2～12月对古尔班通古特沙漠南缘2年生人工梭梭和沙拐枣混交林内3条典型坡面土壤水分进行了系统监测与研究。结果表明:人工林土壤水分状况受季节性降水、人工林种植密度、地形因子的影响而出现明显的时空分异。在空间上将土壤水分变化划分为三层,0～30cm为活跃层,30～60 cm为次活跃层,60～120 cm为相对稳定层。通过主成分分析,得出地形因子、种植密度对0～30 cm土层土壤水分的影响次序为坡度>坡向>种植密度>高程,30～60 cm土层为坡向>种植密度>坡度>高程,60～120 cm土层为种植密度>高程>坡度>坡向

On the study of the Inoculation Effect of SiC to Cast Iron

In order to investigate the effects of silico carbide as inoculant to cast iron, the authors tried to inoculate on the molten iron consisted of carbon equivalent from 3.3 to 3.9 percent. And as inoculants, used silico-carbide, silico-carbide mixed with 5 percent of aluminium compared with those of ferro-silicon. The inoculation of silico-carbide had not special nice influence when it was used in similar range of carbon equivalent which have been studied on the inoculation effects of calcium-silicon and ferro-silicon. The authors are going to research on the effective application of silico-carbide inoculation to the mechanical and other properties of cast iron.鋳鉄に対する接種剤としてはCa-Si及びFe-Siなどが用いられているが最近SiCも接種剤として種々検討されているようである。本実験ではこのSiCの接種効果を調べるために，とりあえず従来Ca-SiやFe-Siについて行っていた炭素当量の範囲内でFe-Siとの比較実験を行った。尚Fe-Siは接種効果を有するためには少量の活性元素Ca又はAlを含有することが必要ともいわれているので本実験ではSiC単独のものとSiCに5%のAlを混合したものも用いてみた

Clinical results of total prostatectomy

1988年までの27年間に進行癌を含む63例の前立腺癌に対し全摘除術をおこなった.術前治療, 去勢術あるいは所属リンパ節郭清術の併用有無別に再発, 癌死, 生存成績について検討した結果, 補助療法を加えた全摘除術は臨床的早期癌や進行癌に対して優れた成績を示した.症例に応じた適切な補助療法の選択が今後の課題であると考えるRadical surgery was administered to 63 patients with prostatic carcinoma, of whom 48 were put under total prostatectomy, 13 under cystoprostatectomy and 2 under pelvic exenteration. Adjuvant therapy was given in three forms: pretreatment to 31 patients, castration to 44 patients and pelvic lymphadenectomy to 39 patients. The 7 patients in stage A survived without carcinoma. Of the 25 patients in stage B, recurrence was seen in 7 patients but there were no deaths and the 5- and 10-year cumulative survival rates were both 86%. Of the 24 stage C patients, 8 developed recurrence, 4 died with the disease, and the 5 and 10 year cumulative survival rates were 82% and 55% respectively. There were 7 stage D patients, of whom 3 developed recurrence and 2 died, and these patients had a 5 year cumulative survival rate of 86%. The results demonstrated that total prostatectomy with suitable adjuvant therapy is useful for advanced carcinoma as well as clinically early stage carcinoma

Incontinent urinary diversion

1)膀胱癌に対する膀胱全摘除術時に尿路変更として, 回腸導管を188例に, 尿管瘻を49例に行った.2)術後30日以内の死亡はなかった.3)術後の早期合併症は, 回腸導管94, 尿管瘻18, 晩期合併症は, 回腸導管85, 尿管瘻23に認められた.合併症を認めなかったのは, 回腸導管49, 尿管瘻14であった.4)回腸導管の術後早期合併症は, 創感染(29%), 消化管疾患(13%), 上部尿路疾患(12%)が多くみられ, 晩期合併症は, ストーマの異常(26%), 上部尿路疾患(14%), 肝炎(13%)が多くみられた.5)回腸導管はWe analyzed 237 patients who underwent total cystectomy with ileal conduit urinary diversion or cutaneous ureterostomy at the Center for Adult Diseases, Osaka. One-hundred and eighty-eight patients underwent ileal conduit diversion and 49 patients underwent cutaneous ureterostomy. No patient died within 30 days after the operation, but two patients who underwent ileal conduit diversion died of postoperative complications within 2 months. Early complications occurred in 94 patients (50%) in the ileal conduit group and in 18 patients (37%) in the ureterostomy group. Late complications occurred in 85 patients (45%) in the ileal conduit group and in 23 patients (47%) in the ureterostomy group. Frequent early complications in the ileal conduit group were wound infection (29%), and intestinal complications (13%) which included ileus and upper urinary tract complications (12%). The most frequent late complications were stomal complications (26%) which included peristomal dermatitis stomal stenosis, parastomal hernia, and stomal prolapse, and upper urinary tract complications which were noted in 27 patients (14%)
