This study was to investigate whether cultivated ginseng (CG), cultivated wild simulated ginseng (CWG) and cultivated red ginseng (CRG) extracts influences on the obesity. The saponin contents of 3 kinds of ginsengs were analysed by HPLC-ESI-TOF-MS. Total saponin contents were determined in CG on the most contents and since red ginseng has the highest PD (protopanaxadiol type) / PT (protopanaxatriol type) ratio, there may be differences between ginseng, wild ginseng, and red ginseng with respect to their pharmacological effects. Male C57BL/6J mice were fed a normal diet(N), HFD (60% Kcal fat, C), HFD with CG, CWG and CRG extracts (800 mg/kg) for 5 weeks. We observed change of total body weight, degree of hepatic lipid accumulation and immunohistochemical change of GLP-1 and insulin-secreting cells. Also this study attempts to use the physiological analysis method to analyze the changes of blood lipids, insulin and leptin concentration. The change of body weight and size of accumulated lipid droplets in liver lobules decreased in all of the experimental groups than the control(C) group. In the pancreas, the immunohistochemical density of insulin-secreting cells were significantly stronger in the CWG and CRG than C group. The levels of serum insulin and leptin significantly decreased 55.6%, 54.3% respectively in CWG and CRG. The changes of triglyceride, total cholesterol in serum decreased in CRG than the C group. Obesity related CG, CWG and CRG extracts might have contribute to improvement of obesity by regulating the levels of blood lipids and biochemical indicator of fat accumulation.
Epithelial-mesenchymal interaction plays a important role in cell growth and differentiation. This interaction is already well known to have an importance during the organ development as well as cell growth and differentiation. However, in vitro experimental model is not well developed to reproduce in vivo cellular microenvironment which provide a epithelial-mesenchymal interaction. Because conventional monolayer culture lacks epithelial-mensenchymal interaction, cultivated cells have an morphologic, biochemical, and functional characteristics differ from in vivo tissue. Moreover, it's condition is not able to induce cellular differention due to submerged culture condition. Therefore, the aims of this study were to develop and evaualte the in vitro experimental model that maintains epithelial-mesenchymal interaction by organotypic raft culture, and to characterize biologic properties of three-dimensionally reconstituted oral keratinocytes by histological and immunohistochemical analysis. The results were as follow; 1. Gingival keratinocytes reconstituted by three-dimensional organotypic culture revealed similar morphologic characteristics to biopsied patient specimen showing stratification, hyperkeratinosis, matutation of epithelial architecture. 2. Connective tissue structure was matured, and there is no difference during stratification period of epithelial 3-dimensional culture. 3. The longer of air-exposure culture on three-dimensionally reconstituted cells, the more epithelial maturation, increased epithelial thickness and surface keratinization 4. In reconstitued mucosa, the whole epidermis was positively stained by anti-involucrin antibody, and there is no difference according to air-exposured culture period. 5. The Hsp was expressed in the epithelial layer of three-dimensionally cultured cells, especially basal layer of epidermis. The change of Hsp expression was not significant by culture stratification. 6. Connexin 43, marker of cell-cell communication was revealed mild immunodeposition in reconstitued epithelium, and there is no significant expression change during stratification. These results suggest that three-dimensional oragnotypic co-culture of normal gingival keratinocytes with dermal equivalent consisting type I collagen and gingival fibroblasts results in similar morphologic and immunohistochemical characteristics to in vivo patient specimens. And this culture system seems to provide adequate micro-environment for in vitro tissue reconstitution. Therefore, further study will be focused to study of in vitro gingivitis model, development of novel perioodntal disease therapeutics and epithelial-mensenchymal interaction.

The objective of this study was to investigate the organic solubilization (SCOD) and improvement of methane production for pig slurry by thermal hydrolysis. A sludge cake was pretreated by thermal hydrolysis at different reaction temperatures (200, 220, 250, $270^{\circ}C$). Ultimate methane potential (Bu) was determined at several substrate and inoculum (S/I) ratios (1:9, 3:7, 5:5, 7:3 in volume ratio) by biochemical methane potential (BMP) assay for 73 days. Pig slurry SCOD were obtained with 98.4~98.9% at the reaction temperature of $200{\sim}270^{\circ}C$. Theoretical methane potentials ($B_{th}$) of thermal hydrolysates at the reaction temperature of $200^{\circ}C$, $220^{\circ}C$, $250^{\circ}C$, $270^{\circ}C$ were 0.631, 0.634, 0.705, $0.748Nm^3\;kg^{-1}-VS_{added}$, respectively. $B_u$ of $200^{\circ}C$ thermal hydrolysate were decreased from $0.197Nm^3\;kg^{-1}-VS_{added}$ to $0.111Nm^3\;kg^{-1}-VS_{added}$ with the changes of S/I ratio from 1:9 to 7:3, and also $B_u$ of different thermal hydrolysates ($220^{\circ}C$, $250^{\circ}C$, $270^{\circ}C$) showed same tendency to $B_u$ of $200^{\circ}C$ thermal hydrolysate according to the changes of S/I ratio. Anaerobic biodegradability ($B_u/B_{th}$) of $200^{\circ}C$ thermal hydrolysate at different S/I ratios was decreased from 32.2% for S/I ratio of 1:9 to 17.6% for S/I ratio of 7:3. $B_u/B_{th}$ of $220^{\circ}C$, $250^{\circ}C$, and $270^{\circ}C$ thermal hydrolysat were decreased from 36.4% to 9.6%, from 31.3% to 0.8%, and from 26.6% to 0.8%, respectively, with the S/I ratio change, respectively. In this study, the rise of thermal reaction temperature caused the decrease of anaerobic digestibility and methane production while organic materials of pig slurry were more solubilized.
The current study was performed to investigate the effects of dietary supplementation of dried coffee meal (CM) on growth performance, intestinal and blood biochemical index, intestinal enzymes, and cecal microbial populations. A total of 162, 3-day-old male broiler chicks were randomly allocated into three dietary groups: control group (CON), basal diet added with 0.5% CM (CM I), and basal diet added with 1.0% CM (CM II). Dietary supplementation of CM did not change bird performance and the relative weight of intestinal mucosal tissues. The birds fed the diet supplemented with CM (0.5 and 1.0%) significantly decreased mucosal glucose concentration (P<0.05) without affecting blood glucose level compared with those fed control diet. The level of blood aspartate aminotransferase (AST) significantly increased in CM II group (P<0.05) without affecting ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GTP) compared with that in the CON group. The specific activity of intestinal maltase, leucine aminopeptidase (LAP) and alkaline phosphatase (ALP) were not affected by dietary supplementation of CM, whereas sucrase activity in birds fed the diet supplemented with CM was decreased (P<0.05) compared to that in the control birds. The colony forming units (CFU) of E. coli in the cecum of CM-fed birds was significantly decreased (P<0.05) compared with that of control birds without changing the CFU of Lactobacillus. In conclusion, dietary supplementation of lower level of CM (0.5%) can be used as a beneficial feed resource without liver toxicity in broiler chicks.
A nutritional demand of oyster, Crassostrea gigas larva as part of research for improving of utilization of microalgae being used for the artificial oyster seed production. The change of body growth and biochemical compositions of larvae were investigated during larvae rearing in hatchery. The larvae were cultured in 60 M/T tank and fed mixture 6 different phytoplankton species, Isochrysis galbana (30%), Cheatoceros gracilis (20%), Pavlova lutheri (20%), Phaeodactylum triconutum (10%), Nannochryis oculata (10%) and Tetraselmis tetrathele (10%). The initial feeding amount was $0.3{\times}10^4cells/mL$ at three times a day to D-shaped larva and the feeding amount had been increased 30% gradually every two day since the larvae were raising. The larvae were developed from D shape to pediveliger stage for 12 days. The daily growth of shell length and hight were $5.8{\sim}30.8\;{\mu}m$ and $8.7{\sim}31.4\;{\mu}m$, respectively and weight gains were changed from D shape to pediveliger as follow: wet weight was $0.52{\sim}15.0\;{\mu}g/larva$, dry weight was $0.2{\sim}6.5\;{\mu}g/larva$, and ash free dry weight was $0.1{\sim}8.5\;{\mu}g/larva$. The larvae growth pattern shown a logarithmic phase from D shape to umbone stage but after that stage shown a exponential growth aspect. The crude protein, crude lipid and nitrogen free extract (NFE) of larvae during rearing periods were analyzed as $6.1{\sim}10.6%$, $0.6{\sim}1.1%$ and 1.0-2.7%, respectively. And the total amino acid contents of the larvae during rearing periods were in order as glutamic acid $1.26{\sim}2.24%$, aspartic acid $0.97{\sim}1.70%$, and methionine $0.12{\sim}0.33%$. Of the total fatty acid in the analyzed larvae, the saturated fatty acid (SSAFA) was decreased from 54.3% (D shaped larvae) to 17.1 % (pediveliger) as larvae development but the total mono-unsaturated fatty acid (${\Sigma}MOFA$) and Poly-unsaturated fatty acid (${\Sigma}PUFA$) were increased from 29.9% and 7.8% to 40.6% and 45.6%, respectively. By the way the each fatty acid of the larvae were composed of palmitic acid $9.89{\sim}36.95%$, oleic acid $12.17{\sim}32.29%$, linoleic acid $1.96{\sim}33.55%$, EPA $2.17{\sim}11.58%$ and DHA $1.95{\sim}4.51%$. As a result of this study, the larvae of oyster were demanded a various nutrients for healthy growth and the feeding control, expecially after umbone stage larvae are a rapidly growing time, is very important for success of artificial seed production.

Fat embolism syndrome is a collection of respiratory, neurological and cutaneous symptoms and signs associated with trauma and other disparate surgical and medical conditions. The incidence of clinical syndrome is low while the embolization of marrow fat appears to be an almost inevitable consequence of long bone fractures. The pathogenesis is a subject of conjecture and controversy. There are two theories which have gained acceptance(mechanical theory, biochemical theory). Onset of symptom is usually within 12 to 72 hours, but may manifest as early as 6 hours to as late as 10 days. The classic triad of fat embolism syndrome involves pulmonary changes, cerebral dysfunction and petechial rash. The cornerstone of treatment is preventing the stress response, hypovolemia and hypoxia and operative stabilization of fractures. Corticosteroid are the only drugs which have repeatedly shown a positive effect on the prevention and treatment of fat embolism syndrome. We report a case of post-traumatic fat embolism syndrome with severe cerebral involvement without respiratory distress. A 55 years old female had a traffic accident. She sustained pelvic bone fracture and both humerus fracture. Approximately 4 hours after the accident, mental status change developed without a focal neurologic deficits. She had no respiratory symptom and sign. Her brain MRI showed multiple cerebral fat embolism lesion. The patients received supportive treatment with corticosteroid, albumin. Her neurologic status stabilized over several days. After orthopedic surgery, she was discharged 62 days after admission.
Objectives : Ganoderma Lucidum has been used in traditional oriental medicine to treat various conditions including chronic fatigue and cough. This experimental study was designed to investigate the effects of yeast-fermented Ganoderma Lucidum extract on the fatigue of rats elicited by forced swimming. Materials and methods : The rat subjects were divided into 4 groups: normal group, control group administered with 0.9% normal saline, experimental I(Exp I) group administered with yeast-fermented Ganoderma lucidum extract and experimental II(Exp II) group administered with Ganoderma lucidum extract for 4 weeks. All the serum samples collected by heart puncture were used to measure biochemical factors such as glucose, lactate, lactate dehydrogenase(LDH), creatine kinase(CK), inorganic phosphorus, ammonia, total cholesterol(TC), triglycerides(TG), high-density lipoprotein(HDL), low-density lipoprotein(LDL), aspartate transaminase(AST), alanine transaminase(ALT). Results : 1. Weight change and swimming time were not significantly different in the experimental groups as compared with control group. 2. Lactate was significantly decreased in the experimental groups as compared with control group. Inorganic phosphorus was also significantly decreased in the Exp I group as compared with control group(p<0.05). 3. Serum lipid concentration was not significantly different in the experimental groups as compared with control group. 4. AST and ALT were significantly decrease in the experimental groups as compared with control group. Conclusions : Yeast-fermented Ganoderma lucidum in forced swimming rats would appear to reduce fatigue-related factors, AST, ALT of serum and promote anti-fatigue effect.
This survey was conducted to obtain basic data about organic matter such as BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), DOC (Dissolved Organic Carbon) and TOC (Total Organic Carbon) in agricultural water in Gyeongnam province. BOD and COD are currently used for water quality indices, but adoption of TOC is being suggested. The surface water samples were collected at 39 locations in Gyeongnam province in April, July and October. Average concentrations of BOD, COD, DOC and TOC were 1.6, 3.3, 5.3 and $5.7mg\;L^{-1}$, respectively. In July, average concentrations of BOD and COD were 2.4 and $3.9mg\;L^{-1}$, respectively, showing these values were higher than other months. Average concentrations of TOC in April, July and October were 4.8, 7.4 and $4.8mg\;L^{-1}$, respectively. This suggested that the highest value of TOC was in July. Average decomposition efficiencies for BOD-C/TOC and COD-C/TOC were 11.4 and 23.9%, respectively. Correlation coefficient of TOC and DOC was higher by 0.995, whereas that of TOC and COD was lower by 0.763. Especially, TOC and DOC were highly related than others.

Background: Korean Red Ginseng (KRG) has been known to possess many ginsenosides. These ginsenosides are used for curing cardiovascular problems. The present study show the protective potential of KRG against doxorubicin (DOX)-induced myocardial dysfunction, by assessing electrocardiographic, hemodynamic, and biochemical parameters and histopathological findings. Methods: Animals were fed a standard chow and adjusted to their environment for 3 days before the experiments. Next, the rats were equally divided into five groups (n = 9, each group). The animals were administered with KRG (250 and 500 mg/kg) for 10 days and injected with DOX (20 mg/kg, subcutaneously, twice at a 24-h interval) on the 8th and 9th day. Electrocardiography and echocardiography were performed to study hemodynamics. Plasma levels of superoxide dismutase, catalase, glutathione peroxidase, and malondialdehyde were measured. In addition, the dose of troponin I and activity of myeloperoxidase in serum and cardiac tissue were analyzed, and the histopathological findings were evaluated using light microscopy. Results: Administration of KRG at a dose of 250 and 500 mg/kg recovered electrocardiographic changes, ejection fraction, fractional shortening, left ventricular systolic pressure, the maximal rate of change in left ventricle contraction (-dP/dtmax), and left ventricle relaxation (-dP/dtmax). In addition, KRG treatment significantly normalized the oxidative stress markers in plasma, dose dependently. In addition, the values of troponin I and myeloperoxidase were ameliorated by KRG treatment, dose dependently. And, KRG treatment showed better histopathological findings when compared with the DOX control group. Conclusion: These mean that KRG mitigates myocardial damage by modulating the hemodynamics, histopathological abnormality, and oxidative stress related to DOX-induced cardiomyopathy in rats. The results of the present study show protective effects of KRG on cardiac toxicity.
Effects of several cytokines($IL-1{\beta},\;TNF_{\alpha},\;and\;IFN_{\gamma}$) have been examined on fetal rat osteoblast-like cells. To investigate whether cytokines play direct causal roles in production of lysosomal enzyme, fetal rat osteoblast-like cells were treated with $IL-1{\beta},\;TNF_{\alpha},\;and\;IFN_{\gamma}$, respectively or combined. And acid phosphatase was determined by biochemical method. Alkaline phosphatase was assayed to determine the effects of $IL-1{\beta},\;TNF_{\alpha},\;and\;IFN_{\gamma}$ on the expression of this enzyme. And also experiment of calcified nodule formation was performed to assess the effects of cytokines on the bone-forming activity of osteoblast-like cells in vitro. Acid phosphatase activity was significantly increased by the addition of $IL-1{\beta}\;and\;TNF_{\alpha}$, whereas decreased by $IFN_{\gamma}$. However, no significant change:: in alkaline phosphatase activity was observed when the osteoblast-like cells were treated with $IL-1{\beta}\;and\;TNF_{\alpha}$. Interestingly, $IFN_{\gamma}$ showed stimulatory effect on alkaline phosphatase activity. The number of calcified nodules was decreased by treatment of cultures with 1 ng/ml $IL-1{\beta},\;20\;ng/ml\;TNF_{\alpha}$, and 500 u/ml $IFN_{\gamma}$ continuously for 21 days, while considerable number of calcified nodules were formed in control group of osteoblast-like cell in culture for 21 days. These results seem to suggest that cytokines may play crucial roles in bone remodeling through the direct action on the osteoblast-like cell.
