For precise property control of sintered products, it is important to understand accurately the packing density of the powder. We developed a packing simulation program that could make a packed bed of spherical particles having particle size distribution. In addition, the influence of the particle shape of the actual powder on the packing density was quantitatively analyzed. The predicted packing densities corresponded well to the actual data.

Background/Aims: The etiology of superficial non-ampullary duodenal epithelial tumors (SNADETs) remains unclear. Recent studieshave reported conflicting associations between duodenal tumor development and Helicobacter pylori infection or endoscopic gastricmucosal atrophy. As such, the present study aimed to clarify the relationship between SNADETs and H. pylori infection and/or endoscopicgastric mucosal atrophy. Methods: This retrospective case-control study reviewed data from 177 consecutive patients with SNADETs who underwent endoscopicor surgical resection at seven institutions in Japan over a three-year period. The prevalence of endoscopic gastric mucosal atrophyand the status of H. pylori infection were compared in 531 sex- and age-matched controls selected from screening endoscopies attwo of the seven participating institutions. Results: For H. pylori infection, 85 of 177 (48.0%) patients exhibited SNADETs and 112 of 531 (21.1%) control patients were non-infected(p<0.001). Non-atrophic mucosa (C0 to C1) was observed in 96 of 177 (54.2%) patients with SNADETs and 112 of 531 (21.1%)control patients (p<0.001). Conditional logistic regression analysis revealed that non-atrophic gastric mucosa was an independent riskfactor for SNADETs (odds ratio, 5.10; 95% confidence interval, 2.44–8.40; p<0.001). Conclusions: Non-atrophic gastric mucosa, regardless of H. pylori infection status, was a factor independently associated with SNADETs.

한국(韓國), 대만(臺灣), 일본(日本)에서 사육(飼育)하고 있는 꽃사슴(Cervus nippon) 129두(頭)와 물사슴(Cervus unicolor) 7두(頭)에서 hemoglobin, transferrin, albumin carbonic anhydrase, slow-${\alpha}_2$ 및 amylase형(型)을 전기영동(電氣泳動)에 의(依)하여 분석(分析)한 결과(結果) 다음과 같은 결론(結論)을 얻었다. 1. cellulose acetate에 의(依)한 전기영동(電氣泳動)이 starch gel에 의(依)한 전기영동(電氣泳動)보다 hemoglobin형(型) 분리(分離)에 있어서 더 간편하며 시간이 적게 걸리고, 선명(鮮明)할 뿐만 아니라 영구보존(永久保存)이 가능(可能)하다. 2. 꽃사슴의 hemoglobin형(型)은 $Hb^F$, $Hb^{FS}$, $Hb^S$형(型)으로 분리(分離)되었으나 물사슴에 있어서는 전부(全部) $Hb^F$형(型)으로 나타났다. 3. hemoglobin ${\beta}$ chain은 4가지형(型) 즉 ${\beta}$-1, ${\beta}$-2, ${\beta}$-3 및 ${\beta}$-4로 분리(分離)되었다. 4. hemoglobin ${\alpha}$ chain은 ${\alpha}_1$과 ${\alpha}_1{\alpha}_2$형(型)으로 분리(分離)되었다. 5. slow-${\alpha}_2$형(型)은 A형(型)과 AB형(型)으로 분리(分離)되었으며, 꽃사슴에 있어서는 AB형(型)이 12% 출현(出現)하였으나 물사슴에서는 전부(全部) A형(型)으로 AB형(型)은 없었다. 6. albumin형(型)에서는 F형(型)과 S형(型)으로 분리(分離)되었으며 꽃사슴은 전부(全部) F형(型)이였고, 물사슴은 전부(全部) S형(型)이였다. 7. transferrin형(型), carbonic anhydrase형(型) 및 amylase형(型)은 전부(全部) 각각(各各) 1종류(種類)의 형(型)이였다.
