  • Gastric necrosis due to gastric outlet obstruction is a very rare condition, but it might be fatal if missed or if diagnosis is delayed. Our patient was a 73-year-old male complaining of abdominal pain, distension and dyspnea for 1 day. In plain radiography and computed tomography, a markedly distended stomach and decreased enhancement at the gastric wall were noted. He underwent explo-laparotomy, and near-total gastric mucosal necrosis accompanied by sludge from the soaked laver was noted. A total gastrectomy with esophagojejunostomy was performed, and he recovered without sequelae. Final pathologic examination revealed advanced gastric cancer at the antrum with near-total gastric mucosal necrosis.

  • We examined the removal of hazardous heavy metals (Cd, Cr, and Pb) from laver Pyropia sp. using citric, hydrochloric, and nitric acids. Under the same conditions, the quality of the laver samples was also evaluated using the variation in absorbance and major mineral levels. The heavy metals that accumulated in raw laver samples after 3 days in seawater included Pb (117.79 μg/g), Cr (33.53 μg/g), and Cd (10.54 μg/g) in descending order. The rate of heavy metal removal from laver was higher at lower pH for all acids used. However, its color changed unsatisfactorily at pH 2.0. After 10 min in seawater at pH 2.5, the heavy metals in laver were eliminated in the order Cd (68.7–81.6%), Pb (57.7–67.0%), and Cr (31.9–49.4%) using the three acids. The differences in heavy metal removal among acid types were not significant. The laver quality was not affected after 20 min at the pH range of 2.5–4.0. The maximum removal of heavy metals was from laver soaked for 10 min in seawater at pH 2.5 using the organic acid, citric acid.

  • This study was conducted to determine the reasonable soaking period of glutinous rice for laver Bugak (Korean traditional fried dishes) processing and to identify the sensory characteristics of three kinds of laver Bugak made with different starch pastes: GRice_1d using glutinous rice soaked for 1 day; GRice_7d using glutinous rice fermented for 7 days; and Wheat using flour. Descriptive analysis was performed by 10 trained panelists, and the 92 consumers evaluated the overall acceptance (OL), acceptance of appearance (APPL), odor (ODL), flavor (FLL), and texture (TXTL) of the samples using a 9-point hedonic scale. From the measurement result by scanning electron microscope (SEM), there were differences in the surface characteristics among soaking period for 1 day and 7 days. Ten panelists were trained, and they evaluated the appearance, odor/aroma, flavor/taste, texture/mouth feel, and after taste attributes of these samples. 36 attributes were generated by panelists and 12 attribute were significantly different across products (p<0.05). It was found that the Grice_7d sample was characterized by mouthfeel of crispiness and uniformity of bubbles, and the Wheat sample was characterized by surface of roughness, mouthfeel of crispiness and adhesiveness, relatively. And the Grice_1d sample was characterized by surface of roughness, mouthfeel of roughness, hardness, cohesiveness, toughness, and adhesiveness.
