  • Critically ill trauma patients generally show good nutritional status upon initial hospitalization. However, they have a high risk of malnutrition due to hyper-metabolism during the acute phase. Hence, suitable nutritional support is essential for the optimal recovery of these patients; therefore, outcomes such as preservation of fat-free mass, maintenance of immune functions, reduction in infectious complications, and prevention of malnutrition can be expected. In this report, we present the experience of a patient subjected to 40 days of nutritional interventions during postoperative intensive care unit (ICU) care. Although the patient was no malnutrition at ICU admission, enteral nutrition (EN) was delayed for > 2 weeks because of several postoperative complications. Subsequently, while receiving parenteral nutrition (PN), the patient displayed persistent hypertriglyceridemia. As a result, his prescription of PN were converted to lipid-free PN. On postoperative day (POD) #19, the patient underwent jejunostomy and started standard EN. A week later, the patient was switched to a high-protein, immune-modulating formula for postoperative wound recovery. Thereafter, PN was stopped, while EN was increased. In addition, because of defecation issues, a fiber-containing formula was administered with previous formula alternately. Despite continuous nutritional intervention, the patient experienced a significant weight loss and muscle mass depletion and was diagnosed with severe malnutrition upon discharge from the ICU. To conclude, this case report highlights the importance of nutrition interventions in critically ill trauma patients with an increased risk of malnutrition, indicating the need to promptly secure an appropriate route of feeding access for active nutritional support of patients in the ICU.

  • Lipid soluble vitamin E consists of tocopherols and tocotrienols depending upon double bonds in phytyl side chains attached to chromanol ring. Recent reports on antioxidative, anticancer, and cholesterol-lowering effects of tocotrienols have increased researches and commercialization of tocotrienols. Purple perilla (Perilla frutescens var. acuta Kudo) has been reported as a plant containing tocotrienols along with tocopherol forms of vitamin E based upon normal phase HPLC analysis. To confirm the existence or absence of tocotrienol form of vitamin E in purple perilla, comparative analysis using HPLC, GC/FID, and GC/MSD has been conducted for 14 purple perilla genetic accessions collected from Korea and Japan. Normal phase HPLC analysis showed ${\alpha}-$, ${\beta}-$, ${\gamma}-$, and ${\delta}-tocopherols$ along with peaks with retention times quite similar to ${\beta}-$ and ${\gamma}-tocotrienols$. Same purple perilla samples, analysed by GC exhibited ${\alpha}-$, ${\beta}-$, ${\gamma}-$, and ${\delta}-tocopherols$ quantitatively equivalent to HPLC results. However, no peaks for ${\beta}-$ and ${\gamma}-tocotrienols$ could be observed and unknown two peaks of similar retention times with ${\beta}-$ and ${\gamma}-tocotrienols$ were identified not corresponding tocotrienols by GC/MSD. These results suggest the absence of tocotrienol form of vitamin E in purple perilla as well as the necessity of using GC-based qualitative and quantitative vitamin E analysis to avoid misinterpretation of peaks with similar retention times as tocotrienol isomers when analysed by an HPLC.

  • This study is investigated the effect on mechanism of nephrotoxicity formation of methotrexate(MTX) by hyperglycemic by streptozotocin(STZ). MTX was injected daily at two doses of 3, 6 mg/kg for 1 week in STZ-induced hyperglycemic rats. Activities of BUN, creatinine and LDH were significantly increased by treatment with MTX in STZ-induced diabetic group when compared to MTX treatment group in normal rats' Renal lipid peroxide content and activities of cytosolic enzyme were significantly increased in the treatment of MTX in diabetic group. The concentration of glutathione and glutathione biosynthesis enzymes were decreased by treatment with MTX in STZ-induced diabetic group. These results suggest that nephrotoxicity of MTX in STZ-induced hyperglycemic rat was caused by activation of renal metabolizing enzymes in cytosol and decrease of glutathione concentration.

  • Solid phase enzyme linked immunosorbent assay (ELISA) was developed to detect the whole cells of Edwardsiella tarda from infected tissues of flounder. Cross-reaction test was performed by ELISA against fish pathogens such as A. hydrophila ATCC7966. V. anguillarum HYUFP5001, Y, ruckeri 11-4, E. ictaluri and Streptococcus sp. NG8206. Rabbit anti-E, tarda Edk-2 sera highly cross-reacted with A. hydrophila ATCC7966 and V. anguillarum HUFP5001. However, the cross-reaction was removed by using the anti-serum pre-adsorbed with A, hydrophila ATCC7966 FKC. The intra-species cross-reaction among E. tarda isolates was very high. ELISA with the whole cell antigens present in tissue homogenate appeared with highly decreased sensitivity, presumably by the co-coating of lipid or proteins in tissues. Thus, it would be necessary to use the infected tissue homogenates diluted more than 100 times with PBS for diagnosis. Interestingly, compared with the using of FKC antigen, the direct detection of viable cells in tissue homogenate showed more sensitive results with detection limit of $1{\times}10^3$ cells/ml in buffer or diluted tissue homogenate. Consequently, the ELISA method developed in this study was specific, rapid and sensitive for diagnosing edwardsiellosis.

  • Band 3, the predominent 95,000 dalton anion transport protein, is the major intrinsic glycoprotein of the human erythrocyte membrane. This anion carrier exists as a dimer and binds the cytoskeletons such as spectrin, ankyrin and actin. And the liposomes are vesicular structures which form spontaneouly upon hydration of phospholipids. These artificial lipid vesicles have been investigated as model of the biological membranes and as a mean of improving the delivery of nucleic acids, drugs, proteins and biological substances to specific target tissues and cells. In this study, we were purified Band 3 from the human erythrocyte membrane(ghost) was prepared by hemolysis of intact human erythrocyte with weak alkali-hypotonic solution. Band 6 was removed from ghost by extracting with solution of an ionic strength of 0.15. Band 3 and Band 4 were solubilized selectively by extracting Band 6-depleted ghosts with Triton X-100 under nondenaturing conditions. Band 3 was then purified from Triton X-100 extract treated with p-chloromercuribenzoate by sucrose density gradient ultracentrifugation. This purified Band 3 was incorporated into liposomes prepared by reverse-phase evaporation. Phosphatidyl L-serine and cholesterol(1 : 1 molar ratio) were dissolved in chloroform and then chloroform was removed by rotatory evaporation under reduced pressure. Band 3 solution without Triton X-100 was introduced into a mixture of lipids and diethylether. Diethylether was subsequently removed by evaporation. This purified Band 3 and its incorporation into liposomes were confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

  • Larvae of the freshwater shrimp, Macrobrachium nipponense(De Haan) were reared in the laboratory under constant conditions ($25^{\circ}C,\;7\%0$ S), and their feeding rate, oxygen consumption, ammonia nitrogen excretion, and growth were measured at regular intervals during development from hatching to post larval stage. Growth was measured as dry weight, carbon, nitrogen, hydrogen, protein and lipid. All these physiological and biochemical traits revealed significant changes from instar to instar. Average feeding rate was high in intermolt stage of the molt cycle and it showed a bell-shaped pattern. Respiration(R) increased from hatching to post larval stage. Excretion(U) increased in intermolt phase of larvae and it showed a bell-shaped variation pattern, in all larval instars with a maximum near the middle of the molt cycle. Regression equations describing rates of feeding, growth, respiration and ammonia excretion as functions of time during individual larval molt cycles were inserted in a simulation model, in order to analyse time-dependent patterns of variation as well as in bioenergetic efficiencies. Carbon was initially increased and nitrogen showed a tendency to increase in premolt phase during individual molt cycles. Protein remained clearly the predominant biochemical constituent in larval biomass.

  • Coenzyme Q10 (CoQ10) is a natural lipid cofactor with antioxidant and anti-aging properties as cosmetic and food ingredients, involved in cellular energy metabolism. Here, nano-emulsions with CoQ10 were fabricated with lecithin, ethanol, oil, and sorbitan monostearate (Arlacel 60), as major components. Phase inversion emulsion method with ultrasonicator was utilized in producing CoQ10 solution, and stabilization effects from lecithin and ethanol and other diverse perturbation factors were evaluated over time. Physical properties of the emulsion were characterized such as its size, surface charges by zeta-potential, and the overall structures. Optimal concentrations of CoQ10 and Arlacel 60 were 0.8% and 3%, respectively, for producing the smallest sizes of nanoemersions in a 100 nm diameter with best morphology. No notable changes in the size were observed over 7 days from Ostwald ripening, when the concentration of Arlacel 60 was higher than 2%. Even after 270 days at room temperature, the size of nanoemulsions maintained as 115 nm in diameter, revealing only a 10% increase with high degrees of long termed stability and substantiality. In addition, changes in the surface potential occurred possible due to the flocculation effect on the nanoparticles.

  • The present study was undertaken to evaluate the anti-hyperlipidemic activity of Albizzia julibrissin and Cassia tora L. extract mixtures in high fat diet-induced hyperlipidemic rats. In high-fat diet fed hyperlipidemic rats, oral treatment with Albizzia julibrissin and Cassia tora L. extracts resulted in decreased levels of total serum cholesterol and triglycerides, epididymal fat pad (EFP) weights, and activities of hepatic glucose-6-phosphate dehydrogenase (G6PDH) and malic enzyme, while the levels of feces production and high-density lipoprotein (HDL)-cholesterol were increased, compared with untreated control. Therefore, these results suggest that Albizzia julibrissin and Cassia tora L. extract mixtures can ameliorate hyperlipidemia.

  • Chungkookjang was fermented by B. subtilis MC31, a ${\gamma}$-amino butyric acid (GABA) producing microorganism. The characteristics of Chungkookjang were investigated while fermenting. Twenty four amino acids were detected in Chungkookjang, leucine was the highest of them all. Total cell populations of B. subtilis MC31 phase were between log $9.52{\pm}0.5$ ~ log $9.049{\pm}0.5$ CFU/g at stationary phase. Contents of moisture, crude ash, crude protein, crude lipid and crude fiber are $61.07{\pm}0.01%$, $1.52{\pm}0.01%$, $17.66{\pm}0.04%$, $8.96{\pm}0.03%$ and 2.61%, respectively. Contents of ammonia type nitrogen, amino type nitrogen and reducing sugar were increased during fermentation at $40^{\circ}C$ for 72 hr, however those of titratable acidity and total sugar were decreased. pH was slowly alkalized during fermentation. Viscous substance and protease contents in Chungkookjang were $4.7{\pm}0.05%$ and $0.519{\pm}7.36$ g/l, apiece. When the fibrin plate and Robbin method for fibrinolytic activity were applied, B. subtilis MC31 showed high activity. These results suggested that B. subtilis MC31 is suitable to be used as a starter to enhance the quality of Chungkookjang.

  • Structured lipid (SL) was synthesized by enzymatic interesterification with algae oil containing docosahexaenoic acid (DHA) and soybean oil in the stirred-batch type reactor. The reaction was performed for 15hr at $65^{\circ}C$ with 300 rpm catalyzed by sn-1,3 specific Lipozyme RM 1M lipase from Rhizomucor miehei ($11\%$ by weight of total substrates) in the absent organic solvent. SL contained $87.1\;area\%$ triacylglycerol (TAG), $12.1\;area\%$ diacylglycerol (DAG), $0.6\;area\%$ monoacylglycerol (MAG), and $0.2\;area\%$ free fatty acid (FFA). Major fatty acid profiles of SL were DHA $(15.7\;mol\%)$, linoleic $(31.1\;mol\%)$, palmitic $(20.2\;mol\%)$, oleic $(13.5\;mol\%)$ and eicosapentaenoic acid $(EPA,\;6.6 mol\%)$. SL contained the newly synthesized several peaks. Iodine and saponification of SL were 206.7 and 183.8. SL color showed darker and redder than soybean oil, and appeared the most yellowish color among SL, soybean, and algae oil.
