  • Purpose: This study was designed to investigate whether nutritional supply influences biochemical markers and clinical outcomes in patients who received continuous renal replacement therapy (CRRT) by evaluating adequacy of nutritional supply for patients. Methods: From January 2012 to December 2013, 239 adult patients who received CRRT in the intensive care unit for more than 3 days were included. General information from electronic medical records and nutritional status related biochemical data and clinical outcomes on the first day of CRRT and 2 weeks after CRRT were collected. Results: The rate of delivered energy and protein was 68.06% and 43.13% which was much lower than energy and protein supply based on their requirement. When the patients were divided into two groups according to 70% of energy received rate and 50% of protein received rate, the group with more than 70% of energy received rate showed significant decrease of length of hospital stay (p = 0.007), length of stay in intensive care unit (ICU) (p = 0.008), duration of CRRT (p < 0.001), and APACHE II score (p < 0.001) compared to less than 70% of energy received rate after adjusting for age. In addition, the group with more than 50% of protein received rate showed decreased mortality (p = 0.031), length of hospital stay (p = 0.008), length of ICU stay (p = 0.035), duration of CRRT (p < 0.001), and APACHE II score (p < 0.001) after adjusting for age. We found that the level of hematocrit (p = 0.006) was significantly improved in the group with more than 70% of energy received rate, and the level of TLC (p = 0.049), hematocrit (p = 0.041) was significantly improved in the group with more than 50% of protein received rate. We also found that energy delivery was negatively correlated with length of stay in ICU (p = 0.049) and positively correlated with level of calcium (p = 0.037). In addition, protein delivery was correlated with the levels of serum total protein (p = 0.021), serum albumin (p = 0.048), hematocrit (p = 0.009), and total cholesterol (p = 0.021) when dead patients were included, but was correlated with the levels of hematocrit (p = 0.034) and calcium (p = 0.024) when dead patients were excluded. Conclusion: Proper nutritional delivery may help patients' clinical outcomes for patients receiving CRRT. However, their actual intakes of energy and protein were not adequate for their requirements. Identification of patients with malnutrition is necessary and a multidisciplinary approach for systemic management is also required.

  • Carotenoids in integument of wild manchurian trout, Brachymystax lenok, and wild and cultured masu salmon Oncohynchus macrostomus, which are all the Korean native cold fresh water fish, were investigated by thin layer chromatography, column chromatography and HPLC. The total carotenoid contents of the wild manchurian trout were $3.72\;mg\%$ which is relatively higher compare to other species of salmonidae. The carotenoids were composed of $36.9\%$ zeaxanthin and $14.7\%$ $\beta-carotene$ as the major compounds, $7.8\%$ triol $7.3\%$ isocryptoxanthin, $5.7\%$ 4-hydroxy echinenone, $4.7\%$ lutein, $4.5\%$ salmoxanthin and $2.2\%$ astaxanthin as minor compounds, and other carotenoids such as canthaxanthin, tunaxanthin A, tunaxanthin B, tunaxanthin C, $\beta-cryptoxanthin$ and $\alpha-cryptoxanthin$ as minute carotenoids. Wild masu salmon contained more total carotenoids than cultured one and the contents were $0.82\;mg\%$ and $0.66\;mg\%$, respectively. The composition of the carotenoids from wild masu salmon were $20.7\%$ xeaxanthin, $17.0\%$ isocryptoxanthin and $15.8\%\;\beta-carotene$ as major compounds, and $6.2\%$ triol, $6.1\%$ 4-hydroxy echinenone, $6.1\%$ salmoxanthin, $5.9\%$ canthaxanthin, $5.8\%$ lutein, $4.9\%$ $\alpha-cryptoxanthin$ and $1.0\%$ astaxanthin as minor compounds. The composition of the carotenoids from cultured masu salmon were $19.7\%$ isocryptoxanthin, $18.0\%$ $\beta-carotene$ and $10.3\%$ zeaxanthin as the major compounds, and $8.9\%\;\beta-cryptoxanthin$, $8.5\%\;\alpha-cryptoxanthin$, $8.0\%$ lutein, $7.6\%$ canthaxanthin, $5.1\%$ triol and $2.0\%$ astaxanthin as minor carotenoids. Based on these data, wild masu salmon contained more zeaxanthin, salmoxanthin and 4-hydroxy echinenone while cultured masu salmon contained more $\alpha-cryptoxanthin$, indicating that carotenoid pigment of masu salmon depends on their living conditions. Unlike wild masu salmon, 4-hydroxy echinenone and salmoxanthin which are the characteristic carotenoids of salmons, were not found in the integument of cultured masu salmon. Unlike manchurian trout, both wild and cultured masu salmon did not contain tunaxanthin A, tunaxanthin B and tunaxanthin C.

  • In this study, the antioxidative effects, inhibitory effects on tyrosinase and elastase and components of Castanea crenata leaf were investigated. The free radical (1,1-diphenyl-2-picrylhydrazyl radical, DPPH) scavenging activity ($FSC_{50}$) of extract / fractions of Castanea crenata left was in the order: 50% ethanol extract ($13.6{\mu}g/mL$) < ethyl acetate fraction (6.2) < aglycone fraction (2.1). Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$ of extract / fractions from Castanea crenata leaf extract / fractions on ROS generated in $Fe^{3+}$-EDTA/$H_2O_2$ system were investigated using the luminol-dependent chemiluminescence assay. The order of ROS scavenging activity was in the order: aglycone fraction (0.8) < 50% ethanol extract (0.5) < ethyl acetate fraction (0.3). The scavenging activity ($IC_{50}$ for ${O_2}^{{\cdot}\;-}$ (superoxide anion radical) generated by NBT method was in the order: ethyl acetate fraction (145.5) < aglycone fraction (65.5). The protective effects on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The ethyl acetate fraction exhibited the most prominent cellular protective effect (${\tau}_{50}$, $191.9{\pm}12.2\;min$ at $10{\mu}g/mL$). The inhibitory effect of aglycone fraction ($9.1{\mu}g/mL$) on elastase was higher than oleanolic and ($13.7{\mu}g/mL$). And the inhibitory effect of aglycone fraction ($21.6{\mu}g/mL$) on tyrosinase was higher than arbutin ($226.2{\mu}g/mL$). But 50% ethanol extract rarely exhibited the inhibitory activity on tryosinase and elastase. Flavonoids were contained in Castanea crenata left (96.3 mg / 100 g dried Castanea crenata leaf). And flavonoids contained in ethyl acetate fraction were kaempferol, quercetin, quercitrin, and so on. Quercitrin is the most abundant component. These results indicate that extract / fractions of Castanea crenata can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging free radical and ROS, Castanea crenata leaf extract/ fractions could be used as new cosmeceutical for whitening and anti-wrinkle products.

  • Background : It is important to predict the exercise capacity and dyspnea, as measurements of lung volume, in patients with COPD. However, lung volume changes in response to an improvement in airflow limitation have not been explored in detail. In the present study, it is hypothesized that lung volume responses might not be accurately predicted by flow responses in patients with moderate to severe airflow limitations. Methods : To evaluate lung volume responses, baseline and follow up, flow and lung volumes were measured in moderate to severe COPD patients. The flow response was defined by an improvement in the $FEV_1$ of more than 12.3%; lung volume changes were analyzed in 17 patients for the flow response. Results : The mean age of the subjects was 66 years; 76% were men. The mean baseline $FEV_1$, $FEV_1$/FVC and RV were 0.98L (44.2% predicted), 47.5% and 4.65 L (241.5%), respectively. The mean follow up duration was 80 days. The mean differences in the $FEV_1$, FVC, TLC and RV were 0.27 L, 0.39 L, -0.69 L and -1.04 L, respectively, during the follow up periods. There was no correlation between the delta $FEV_1$ and delta RV values(r=0.072, p=0.738). Conclusion : To appropriately evaluate the lung function in patients with moderate to severe airflow limitations; serial lung volume measurements would be helpful.

  • The purpose of this study was to examine the radiolabeling and biodistribution of $^{188}Re(V)$-DMSA as a therapeutic cancer radiopharmaceutical. We made a DMSA kit($NaHCO_3$ 1.5 mg, meso-2,3-dimercaptosuccinic acid 1.0 mg, L(+)-ascorbic acid 0.7 mg, $SnCl_2{\cdot}2H_2O$ 0.34 mg, pH 2.9) for labeling with $^{188}Re$. In this kit, $^{188}ReO_4{^-}$ 5 mCi/2 ml added and boiled at $100^{\circ}C$ for 3 hr in water bath. The final pH adjusted to 7.5 with 7% $NaHCO_3$ solution. We checked the labelling efficacy with TLC-SG(n-butanol : acetic acid : $H_2O$ = 3 : 2 : 3) and examined the stability both in room temperature and in serum at $37^{\circ}C$. Biodistribution(1, 3, 13, 24, 48 hr) of $^{188}Re(V)$-DMSA compound was evaluated in Sarcoma 180 tumor-bearing mice. Each labeling efficiency and stability at room temperature for 48 hours was over 98% and 95%, respectively. The stability in serum were 82%(6 hr) and 85%(48 hr). Tumor uptake of $^{188}Re(V)$-DMSA in Sarcoma 180-bearing mice were $0.66{\pm}0.15%$(1 hr), $0.51{\pm}0.10%$(3 hr), $0.19{\pm}0.05%$(24 hr) and $0.13{\pm}0.02%$(48 hr). These result are consistent with those of $^{99m}Tc(V)$-DMSA which were reported previously. In conclusion, $^{188}Re(V)$-DMSA may be a useful therapeutic radiopharmaceutical for treating some cancers and metastatic bone lesion.

  • Background: There are reports that food deprivation causes emphysematous changes in the lungs of rats and humans. However, the meaning of this phenomenon in patients with chronic obstructive pulmonary disease has not been evaluated. The aim of this study was to determine the correlations between the caloric intake and parameters of the lung function in patients with chronic obstructive pulmonary disease. Methods: Patients with chronic obstructive pulmonary disease who had visited the respiratory clinic from March, 2006 for one year were enrolled in this study. The patients underwent pulmonary function tests, and a dietitian evaluated their nutritional intake using a food record method. Results: There was no correlation between the total caloric intake and forced vital capacity (FVC, %predicted) or forced expiratory volume in one second ($FEV_1$, %predicted). The total caloric intake showed a positive correlation with the diffusing capacity of carbon monoxide (DLCO %predicted, DLCO/VA %predicted), and a negative correlation with the total lung capacity (TLC, %predicted). Of the calories taken, only calories from protein intake correlated with the diffusing capacity of carbon monoxide (DLCO %predicted, DLCO/VA %predicted). Conclusion: The total caloric intake of patients with chronic obstructive pulmonary disease showed a positive correlation with the diffusing capacity of the lung, and a negative correlation with the total lung capacity. Further study on the linkage between the caloric intake and severity of emphysema is needed.

  • The physiological properties of 70% ethanol extracts from Portulaca oleracea with different extraction methods (reflux extraction, RE; autoclave extraction, AE; low temperature high pressure extraction, LTPE) were investigated. The freeze-dried powder yields of RE, AE, and LTPE were 33.78%, 30.80%, and 11.05%, respectively. The color values of L and b were higher in LTPE, and the chroma values were higher in AE and LTPE compared to RE. The total polyphenolics and proanthocyanidin contents in LTPE were significantly higher than in other extracts. The amount of substances related to flavonoids contents was highest in RE (4.30 mg/g), followed by AE (4.06 mg/g), and LTPE (4.00 mg/g). DPPH radical scavenging ability with a concentration of 500 mg% (w/v) were in the following order; LTPE (88.87%)> RE (83.84%)> AE (80.67%). Further, the reducing power, ABTS radical scavenging ability, and nitrite scavenging activity was observed in the same tendency as seen with the DPPH radical scavenging ability. However, the ferrous ion chelating activity of RE (85.45%) and AE (83.88%) was significantly higher than that of LTPE (75.60%). ${\alpha}$-Glucosidase inhibitory activities of RE and LTPE with a concentration of 100 mg% were significantly higher than AE. Xanthine oxidase, and acetylcholinesterase inhibitory activities of LTPE were higher than the other extracts. These results suggest that the extracts from Portulaca oleracea have the potential to act as functional materials, and components of Portulaca oleracea could be effective in the prevention of Alzheimer's disease, and may be used to develop various functional food products.

  • Oyster (Crassostrea gigas), arkshell (Anadare(Scapharce) broughtonii) and sea-mussel (Mytilus edulis) were investigated as to their lipid classes. Lipid extracts from shellfishes were fractionated into neutral lipid (NL), glycolipid (GL) and phospho-lipid (PL) by column chromatography with silicic acid. The fatty acid compositions of their lipid classes and lipid fractions were determined by gas liquid chromatography (GLC). Total lipid contents of shellfishes were $3.5\%$ in the oyster, $1.4\%$ in the arkshell, $1.0\%$ in the sea-mussel. The major fatty acids of total lipids were palmitic acid, eicosapentaenoic acid and docosahexaenoic acid in the oyster and the sea-mussel, palmitic acid, oleic acid and eicosapentaenoic acid in the arkshell. The lipid composition of neutral lipid fractions in shellfishes was separated and identified as free sterol, free fatty acid, triglyceride, hydrocarbon and esterified sterol by TLC. Of these classes, triglyceride fraction was most abundant, amounting to 55.6, 77.7 and $60.4\%$ in the three samples mentioned above, respectively. The main fatty acids of glycolipid were palmitic acid, eicosaenoic acid and docosahexaenoic acid in oyster, myristic acid, palmitic acid and palmitoleic acid in the arkshell, docosahexaenoic acid, linolenic acid and palmitic acid in the sea-mussel. The major fatty acids of phospholipid were palmitic acid, eicosapentaenoic acid and docosahexaenoic acid in the oyster and sea-mussel, palmitic acid, eicosapentaenoic acid and erucic acid in the arkshell.

  • Lipids extracted from two kinds of sun-dried laver samples, wild Porphyra suborbiculata and cultured Porphyra tenera, produced at Wan-do in Korea were studied. Dried P. suborbiculata contained $0.8\%$ total lipid(TL) which consisted of $21.4\%$ neutral lipid(NL), $53.4\%$ glycolipid(GL) and $25.2\%$ phospholipid(PL), and dried P. tenera contained $1.2\%$ TL which consisted of $30.5\%$ NL, $50.3\%$ GL and $19.2\%$ PL. Among the NL of dried P. suborbiculate and P. tenera, free fatty acid ($41.4\%,\;39.0\%$), triglyceride($25.6\%,\;28.8\%$) and free sterol ($22.1\%,\;16.7\%$) were predominant. Digalactosyl diglyceride ($34.7\%,\;46.6\%$) and monogalactosyl diglyceride ($19.2\%,\;18.0\%$) were the major components among the GL. Sulfoquinovosyl digylceride ($4.2\%$) was also identified in P. tenera only. And main lipids in the PL of P. suborbiculata and P. tenera were phosphatidyl ethanolamine ($40.3\%,\;35.7\%$) and phosphatidyl choline ($28.6\%,\;30.7\%$) and followed by phosphatidyl serine($15.1\%,\;19.2\%$) and phosphatidyl inositol ($16.0\%,\;14.4\%$). The major fatty acids in the TL of the dried P. suborbiculata were 20:5 ($29.4\%$), 16:0 ($23.4\%$) and 20:4 ($13.0\%$), and those of the dried P. tenera were 20:5 ($36.7\%$), 16:0 ($16.2\%$), 16:1 ($10.7\%$) and 18:1 ($9.7\%$). The fatty acid composition of the both samples in the NL fraction were similar to the pattern in those of the TL. The abundant fatty acids in the PL of the both dried laver were 20:5, 16:0 and 18:1. In case of the GL fraction, the main fatty acids of the dried P. suborbiculata were 16:0, 20:5, 18:1 and 20:4, while those of the dried P. tenera were 20:5, 16:0 and 18:1.

  • Termitomyces albuminosus has been recognized to have the best mushrooms in China, in terms of taste and aroma. The efficacy of these mushrooms has been recorded in the botanical list. However, research on the development of their artificial culture methods is necessary. In this study, we prepared an organic solvent extract and a hot water extract to understand the development of compounds and functional foods with antioxidant and anti-inflammatory activities. The IC50 value of DPPH radical scavenging activity of the hot water extract (TA4) was 1.5 mg/mL and the IC50 value of the MeOH fraction (TA2) was 1.93 mg/mL. The anti-inflammatory activity was investigated by the inhibition of NO production. EtOAc fraction (TA1) is a crude extract, but 79% of NO production was inhibited at 100 ㎍/mL. NO was not produced at 200 ㎍/mL. TA1-5-6, from TA1 inhibited NO production by 15% as compared to the positive control at 15 ㎍/mL, and completely inhibited NO production at 30 ㎍/mL. No cytotoxicity was observed at 50 ㎍/mL. TA2-1-5 from the MeOH fraction (TA2) inhibited more than 75% of NO production at 30 ㎍/mL; cytotoxicity was very low even at 50 ㎍/mL. In conclusion, by selective solvent selection, it was possible to manufacture an extract with no cytotoxicity and excellent biological activities. Furthermore, the extracts showed potential for developing various functional foods and drugs.
