PE 필름 두께에 따른 한국산 양다래(Actinidia chinensis Planch .) 의 MA 저장에 관한 연구
이세은,김동만,김길환 한국농화학회 1992 Applied Biological Chemistry (Appl Biol Chem) Vol.35 No.2
For the development of kiwifruit storage method applicable to farm level, several quality indicator of kiwifruit(Actinidia chinensis Planch.) were measured during storage at modified atmosphere(MA) conditions(0.04, 0.06, 0.08 and 0.10 ㎜ PE Film). The results obtained from the experiment were as follows. The highest firmness was marked by the kiwifruit kept in 0.06 ㎜ thick film bag and the lowest weight loss was shown in 0.10 ㎜ thick film bag. The largest production of respiratory rate was occured after storage for 30 days. The concentration of O₂ and CO₂ in 0.06 ㎜ thick film bag was 2.6% and 3.2% after storage for 60 days, respectively. It could be concluded that the optimum PE film thickness for MA storage of kiwifruit was 0.06 mm.

This study investigated effect of extract containing quercetin-3-O-β-D-glucuronopyranoside from Rumex Aquaticus Herba (ECQ) against chronic gastritis in rats. To produce chronic gastritis, the animals received a daily intra-gastric administration of 0.1 ml of 0.15% iodoacetamide (IA) solution for 7 days. Daily exposure of the gastric mucosa to IA induced both gastric lesions and significant reductions of body weight and food and water intake. These reductions recovered with treatment with ECQ for 7 days. ECQ significantly inhibited the elevation of the malondialdehyde levels and myeloperoxidase activity, which were used as indices of lipid peroxidation and neutrophil infiltration. ECQ recovered the level of glutathione, activity of superoxide dismutase (SOD), and expression of SOD-2. The increased levels of total NO concentration and iNOS expression in the IA-induced chronic gastritis were significantly reduced by treatment with ECQ. These results suggest that the ECQ has a therapeutic effect on chronic gastritis in rats by inhibitory actions on neutrophil infiltration, lipid peroxidation and various steps of reactive oxygen species (ROS) generation.
Characteristics of $[^3H]$-Choline Uptake into Synaptosomes from Rat Hippocampus
이세은,홍성길,최림순,Lee, Se-Eun,Hong, Seong-Gil,Choe, Rim-Sun The Korean Society for Integrative Biology 1998 Korean journal of biological sciences Vol.2 No.2
Certain basic characteristics of choline uptake in nerve terminals were studied with synaptosomes from rat hippocampus. Synaptosomal $[^3H]$-choline uptake was clarified as specific and high affinity by low Km value(2.2 uM), Na+-dependency and high sensitivity to hemicholinium-3, a competitive inhibitor of choline uptake. Choline uptake into synaptosomes was linearlys related to Na+ concentration and membrane potential. Extracellular Ca2+ modulated the choline uptake, but probably not through increase of intracellular $Ca^{2+}$, because this modulation was not affected the by high $K^+$-depolarization. EGTA (2mM) added for $Ca^{2+}$-free condition had a peculiar effect of decreasing choline uptake. These results suggest that Ca2+ may play an important role in regulating the metabolism of acetylcholine in the nerve terminals directly through the increase of acetylcholine release.
