The pulping process in a papermaking process for a reconstituted tobacco sheet (RECON) was evaluated. For the practical information, the experiments were conducted in a real mill. Two pulping conditions were chosen and changed depending on the feasibility, such as the pulping temperature and the properties of pulping water. The higher pulping temperature resulted in the easier dissolution of solubles from the raw materials. However, the efficiency of screw press process was decreased by the higher pulping temperature, which resulted in the reduction of the HWS and the concentration in the #1 screw press filtrate. The addition of SEL(Strong extracted liquor) to pulper affected the efficiency of dissolution and the final concentration of #1 screw press filtrate. Although the higher SEL resulted in the less dissolution of the solubles from the raw materials, the concentration of the #1 screw press filtrate was greatly increased by the higher addition of SEL, which could provide much better efficiency to the following evaporation process of the filtrate and could increase the whole productivity.

Background/Aims: Cancers of the gastrointestinal tract might cause chronic occult blood loss leading to iron deficiency. The aim of this study was to determine the usefulness of the tests for iron deficiency in detection of stomach cancer. Methods: Seventy one patients with advanced gastric cancer (AGC), 13 patients with early gastric cancer (EGC), and 104 patients with functional GI disorder (FGID) as a control were consecutively enrolled in this study. The test results for iron-deficiency parameters such as hemoglobin, serum ferritin, serum iron, total iron binding capacity, and transferrin-saturation rates were compared among the groups. Incidence of iron deficiency or anemia was compared among the groups. Results: The levels of hemoglobin, serum ferritin, serum iron, and the rates of transferrin saturation were significantly lower in the AGC group than in the control group. These differences were even marked in male patients. They were not significantly different between the EGC group and the control group. In male patients with AGC, the incidence of anemia or iron deficiency was markedly higher than the control group. Conclusions: In males over 50 years, tests for iron-deficiency parameters such as hemoglobin, serum ferritin, serum iron, and transferrin saturation might be helpful in detection of AGC. Further study is needed to reveal whether these tests are helpful in the early detection of stomach cancer. (Korean J Gastroenterol 2002;39:179-185)

Reports of portal vein aneurysm are scattered in the literature. However, with the increased use of sonography, CT, MRI, it is found incidentally with greater frequency. Clinical presentation ranges from without symptom to hemobilia, hemoperitoneum, thrombosis, compression of adjacent structures, and spontaneous arteriovenous fistula. Sometimes, it is confused with a pancreatic head mass, raising a diagnostic problem. We report a case of extrahepatic portal vein aneurysm confused with pancreatic head cancer. A 45-year-old woman presented with weight loss of 10 kg, and ultrasonography and CT revealed a pancreatic head mass. Laparotomy was performed, but resection of the mass was impossible. Later review of the enhanced spiral CT and angiography revealed that the mass actually represented a portal vein aneurysm. Her condition has remained stable with just clinical observation. Portal vein aneurysm should be considered when there is an enhancing mass adjacent to the portal vein or superior mesenteric vein. (Korean J Gastroenterol 2002;39:137-141)
