The anti-obesity effects of fermented black bean were tested with mice fed a high fat diet for seven weeks. Body weight gain and feed efficiency ratio (FER) in the high fat diet control (HC) group were markedly higher, compared with those of the normal control (NC) group, but were significantly lower in the 2% black bean powder supplemented high fat diet (BB) group and 2% black bean powder fermented by M. pilosus supplemented high fat diet (BBM) group, compared with those of the HC group. Food intake in the HC and BB groups was significantly lower than that of the NC and BBM groups. Water intake in the HC group was significantly lower than that of the NC group, but was higher in the BB and BBM groups, compared with that of the HC group. On the other hand, relative liver and kidney weight in the HC group was lower than that of the NC group, but was higher in the BB and BBM groups, compared with that of the HC group. In addition, whereas epididymal fat weight in the HC group was markedly higher than that of the NC group, it was significantly lower in the BB and BBM groups, compared with that of the HC group. Meanwhile, hepatic GSH in the HC group was significantly lower than that of the NC group, but was slightly higher in the BB and BBM groups, compared with that of the HC group. Although hepatic LPO in the HC group was dramatically higher than that of the NC group, it was significantly lower in the BB and BBM groups, compared with that of the HC group. In addition, serum TG, total cholesterol, and LDL-cholesterol in the HC group was significantly higher than that of the NC group, but was significantly lower in the BB and BBM groups, compared with that of the HC group. On the contrary, HDL-cholesterol in the HC group was significantly lower than that of the NC group, but was higher in the BB and BBM groups, compared with that of the HC group. In addition, activity of XOR D type in the HC group was lower than that of the NC group, but was slightly higher in the BB and BBM groups, compared with that of the NC group. Activities of ROS scavenging enzymes, such as SOD, GPX, and GST in the HC group were significantly lower than those of the NC group, but were significantly higher in the BB and BBM groups, compared with those of the HC group. In addition, serum ALT activity in the HC and BB groups was higher than that of the NC group, but was significantly lower in the BB and BBM groups, compared with that of the HC group. In histopathological findings, hepatic fat accumulation in the HC group was higher than that of the NC group, but was lower in the BBM group, compared with that of the HC and BB groups. In particular, antiobese, hypolipidemic, and antifatty liver effect of black bean powder fermented by M. pilosus was specifically higher than that of non-fermented steamed black bean. In conclusion, the constituents of black bean fermented by Monascus pilosus have been proven to not only inhibit obesity and hyperlipidemia but also decrease hepatic fat accumulation in high fat diet-induced obese mice.

Introduction: In order to investigate the effects of partial Cervus elaphus Linne' extract on antitumoral immunological, a group of mice are melanoma-induced and observed reponses in terms of the number of lymphocyte, CD4+ count, CD8+ count, CD4+/CD8+ ratio in blood and spleen, change in body weight, melanoma weight, spleen index, NK cell activity and productivity of IL-2 in each mouse Methodology: Male C57BL/6 mice were chosen as an experimental object and were divided into 5 groups randomly selection. The normal group did not receive any induction. The control group was treated with normal saline in melanoma-induced' mice. Sample I group induced the upper part of Cervus elaphus Linne' extract in melanoma-induced mice. Sample II group was induced the middle part of Cervus elaphus Linne' extract in melanoma-induced mice. Sample III group was induced the lower part of Cervus elaphus Linne' extract in melanoma-induced mice. The dosage of medication was 0.2cc daily for 14days. Results: 1. There was a significant difference in the number of lymphocyte in spleen in the sample I (upper part of Cervus elaphus Linne' extract induced) and the sample II (middle part of Cervus elaphus Linne' extract induced) compared to the control group and the sample III (lower part of Cervus elaphus Linne' extract induced). On the other hand, no significant difference was observed in the number of lymphocyte in blood in the control group and all sample groups. 2. In the CD4+ T cell ratio in blood, all three sample groups showed differences compared to the control group, though there was no significant difference between sample groups. In the CD4+ T cell ratio in spleen, there was a difference between the sample I and the control group, while the sample II and the sample III had significant difference to the control group. And also, it has been observed there were differences between the sample I and the other samples. 3. In the CD8+ T cell ratio in spleen, all three sample groups showed significant differences compared to the control group, while there was no difference between groups in the ratio in blood. 4. In the CD4+/CD8+ T cell ratio in blood, the sample I showed a significant difference compared to the control group, while the sample 1I and sample III showed differences compared to the control group. In the CD4+/CD8+ T cell ratio in spleen, all three samples showed a significant difference compared to the control group, when the sample I had a difference to the other sample groups. 5. The spleen index of the sample I and the sample II showed a significant difference compared to the sample III and the control group. In comparison between the sample groups, the sample I and the sample II showed a significant difference to the sample III. 6. In terms of the change in body weight and melanoma weight, all three sample groups showed a significant difference compared to the control group, while the comparison between the sample groups showed the sample and the sample II had a significant difference to the sample Ⅲ. 7. In comparison of NK cell activity, the sample I had a difference compared to the other groups when the effector to target cell ratio was 2.5:1. With the ratio of 5:1, the sample I and sample II showed significant differences compared to the control group, while the sample Ⅲ showed a difference. When the effector to target cell ratio was 10:1, there was no difference between groups. 8. In the productivity of IL-2, all three sample groups showed significant differences compared to the control group. In comparison between sample groups, there were significant differences between each sample groups in order of the sample I , the sample II and the sample Ⅲ. Conclusion: As one can witness from the above results, administration of partial Cervus elaphus Linne extract played important role in antitumoral immune response in melanoma-induced mice, and it could be suggested that sample I and sample II groups have prominent antitumoral immune effect.

We previously developed an herbal composition (HemoHIM) based on the water extracts of Angelica gigas radix, Cnidium officinale rhizoma, and Paeonia japonica radix to protect and recover hematopoietic and intestinal tissues against radiation injuries. In this study, to develop a composition with improved activities based on enhanced fat-soluble polyphenol contents, we prepared a new herbal composition, MH-30, from the above three herbs by 30% ethanol extraction and hot water extraction. HPLC analysis of the ethanol fractions of MH-30 and HemoHIM revealed that MH-30 had higher contents of many fat-soluble polyphenol compounds than HemoHIM (8.7-fold increase for decursin), whereas contents of water-soluble polyphenol compounds showed little differences between the two compositions. Then, we evaluated MH-30 and HemoHIM for their in vitro antioxidant and immune cell-stimulating activities as well as in vivo protective effects against radiation injuries in hematopoietic and self-renewal tissues. In antioxidant activity assays, MH-30 showed higher hydroxyl radical scavenging activity than HemoHIM (1.4- to 1.9-fold for compositions and 2.3- to 4.5-fold for ethanol fractions). On the other hand, MH-30 and HemoHIM exhibited similar immune cell-stimulating activities as measured by in vitro lymphocyte proliferation. MH-30 increased endogenous spleen colony formation, decreased bone marrow cell apoptosis, and enhanced survival of intestinal crypts in irradiated mice, demonstrating effective protection of MH-30 against radiation-induced injuries in hematopoietic and self-renewal tissues. The 30-day survival rate of lethally irradiated mice, a comprehensive index for radioprotective efficacy, was also elevated by MH-30. Noticeably, MH-30 showed higher protective effects than HemoHIM in all mouse experiments. These results demonstrate that MH-30 can protect hematopoietic and self-renewal tissues against radiation injuries more effectively than HemoHIM. Therefore, MH-30 can be a good candidate to reduce radiation injuries in hematopoietic and self-renewal tissues incurred by radiation accidents or cancer radiation therapy.

This study examined the protective effects of an ethanol extract of Youngia denticulata leaf (YDL) and Youngia denticulata root (YDR), and Youngia sonchifolia leaf (YSL) and Youngia sonchifolia root (YSR) on acute ethanol-intoxicated rat. The rats were pretreated with an ethanol extract of YDL, YDR, YSL and YSR for 4 weeks before being exposed to ethanol (5 g ethanol, po/kg BW). The biochemical indices (hepatic alcohol metabolic enzymes and serum ALT activities, and hepatic and serum lipid profiles) were examined to evaluate the protective effects. The hepatic ADH activities in all experimental groups were not changed significantly by acute ethanol after a pretreatment with the YS and YD ethanol extracts. In contrast, the ALDH activity in EC (ethanol control) was higher than that of NC (normal control); these activities in the YDL and YSL groups were significantly higher than that of the EC group. On the other hand, acute ethanol exposure resulted in a significant increase in the serum TG, total cholesterol, LDL-cholesterol, hepatic TG, total lipid and cholesterol levels, and serum ALT activity, and a decrease in the serum HDL-cholesterol. A pretreatment with the YS and YD ethanol extracts dramatically attenuated these adverse effects. In particular, the YDL pretreatment markedly suppressed the ethanol-induced increase in the serum and hepatic TG and total cholesterol levels. Furthermore, serum ethanol was decreased by a pretreatment with YSL, YSR, YDL, or YDR. Overall, YD and YS ethanol extracts attenuate acute ethanol-induced hyperlipidemia and fatty liver significantly. Nevertheless, further study will be needed.

This study was performed to obtain the basic data on the serum constituents of several marine fish spesies commonly cultured in Korea. Blood samples taken from six species of fish were analyzed for various components of serum, total protein (TP), albumin (ALB), triglyceride (TRIG), cholesterol (CHOL), glucose (GLC), lipase (LIPA), amylase (AMYL), aspartate transaminoferase (AST), sodium (Na), potassium (K), chloride (CI) and phosphorus (PHOS). The fish used were coho salmon (Oncorhynchus kisutch), rock fish (Sebastes schlegeli), sea bass (Lateolabrax japonicus), olive flounder (Paralichthys olivaceus), rock fish (Sebastes schlegeli), sea bass (Lateolabrax japonicus), olive flounder (Paralichthys olivaceus), parrot fish (Oplegnathus fasciatus) and jack mackerel (Trachurus jaonicus) reared at the Chungmu Experimental Fish Culture Station of KORDI when the water tempetature was ca. 16.5$^{\circ}C$. There were significant differences in TRIG, CHOL, LIPA and AMYZ among the species analyzed. TRIG concentratin were ranged 178~180mg/dl in jack mackeerel and rock fish, 126~159 mg/dl in olive flounder and sea bass, and 102~114 mg/dl in coho salmon and parrot fish, respectively. Jack mackerel showed the highest levels in CHOL (255mg/dl) and GLC(138mg/dl) among species. LIPA levels were recorded 256 U/dl in coho salmon, 41~42 U/dl in parrot fish and rock fisk, and 5~11 U/dl jack mackerel and sea bass, respectively. AMYL activity of coho salmon was measured as 2, 665 U/dl, and that of jack mackerel was 1,210 U/dl while sea bass showed 60 U/dl and parrot fish, olive flounder and rock fish had at most 5 U/dl. On the other hand, there was no significant difference in the concentration of Na and CI. Na and K were proved that they were negatively correlated in all the species. Generally, among blood components, PHOS and CHOL levels were different depending on environmental temperature of each fish species, especially in olive flounder. Rock fish and parrot fish showed high blood concentration of those components during low temperature period while olive flounder and jack mackerel reached high level during their optimal environmental temperature period. The electrolyte concentration and LIPA activity were high during low water temperature period, in general, but TP and ALB concentrations were high during optimal temperature period. The concentrations of TRIG, CHOL and GLC, those which were used as energy sourses, were different among species by season.

This study was carried out to investigate the effect of ethanol extract of antler velvet (EAV) on common serum chemistry panels and histopathological change in rats exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Administration of TCDD ($50{\mu}g/kg$ body weight) induced significant decrease in platelet count (p<0.01), creatine phosphokinase (CPK, p<0.01), lactatate dehydrogenase (LDH, p<0.05) and glucose (p<0.05) levels and increase in hemoglobin (p<0.05), aspartate aminotransferase (AST, p<0.01), alanine amino transferase (ALT, p<0.05) and lipase activities (p<0.05), and blood urea nitrogen (BUN, p<0.05), triglyceride (p<0.01) and low density lipoptotein cholesterol (LDL-C, p<0.05) levels. However, pretreatment of EAV at daily dose of 20 mg/kg b.w. from 1 wk before TCDD exposure for 5 wks attenuated the abnormality of the overall serum chemistry panels but statistical difference between TE and TA groups was observed only in testicular weight (p<0.01), LDH activity (p<0.05), glucose (p<0.05) and lipase activity (p<0.01). In addition, TCDD induced significant histopathological changes including swelling, fatty metamorphosis, and vacuolar degeneration in liver; edema in proximal and distal convoluted tubules, and glomerulus in kidney; severe atrophy of red purple and appearance of significant number of macrophage in spleen; prominent atrophy and decrease in immune cells in thymus. On the other hand, administration of EAV attenuated histopathological damage induced by TCDD. These results further suggest that administration of EAV attenuates TCDD induced testicular, liver, pancreatic, hematopoietic and nephrotic toxicities in rats.

In this study, we used extracts obtained from five different solvents (water, ethanol, hexane, ethyl acetate, butanol) of Achyranthes japonica (AJ) and also AJ fermented with Lactobacillus plantarum (LP) to confirm effects on the anti-inflammatory activity in RAW264.7 cells. Experiments of measuring nitric oxide (NO) and cytokine production were performed in lipopolysaccharide (LPS)-induced RAW264.7 cells, and the expression of both cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) was observed by a western blot method. The cytotoxicity of RAW264.7 was confirmed by the cell counting kit (CCK) assay at a concentration of $100{\mu}g/mL$, which has no toxicity. As a result of the inhibition of NO production, the inhibition rate of AJ-LP extracted with ethanol samples was about 74% higher than that of using the control group. Interleukin-6 (IL-6), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and Interleukin-$1{\beta}$ (IL-$1{\beta}$), which are inflammatory cytokines, also showed an excellent efficacy with inhibition rates of about 57, 70, and 74%, respectively. Comparing to the results of COX-2 and iNOS expression in the AJ group, the inhibition rate of 20-hydroxyecdysone was the highest than others. On the other hand, the COX-2 expression level of AJ-LP group decreased about 16% compared to that of the control group, and the iNOS expression level was also decreased about 7%. These results suggest that the extract of AJ fermented from L. plantarum can be used as an anti-inflammatory natural material.

⁵⁵Fe and ⁶³Ni are key factors in deciding the proper handling of the decommissioning of radioactive waste from nuclear facilities. For determining beta emitting radionuclides, the dismantled waste samples should be completely decomposed and separated from the sample matrix. This study reports the comparison results of the recovering efficiencies of Iron and Nickel with wet digestion methods that use various acids and alkali-fusion methods. Various matrices of NIST SRMs (1646a, 1944, 8704, 2709a, and 1633c), the recovering efficiencies of using alkali-fusion methods ranged from 95.3 to 98.3% for Iron, and from 86.6 to 88.1% for Nickel within about 2% of relative standard deviation. On the other hand, those using one of the three wet digestion methods ranged from 77.9 to 105.3% for Iron and from 40.1 to 78.5% for Nickel with over 10% of relative standard deviation. Therefore, one may draw the conclusion that the analytical results derived from Iron and Nickel using alkali-fusion methods are fairly reliable due to the recovering efficiencies observed.

To evaluate the meat quality differences of Korean Native Chickens (KNC) available in Korean market, the physicochemical and sensory characteristics of a broiler and two KNC (HH and WD breed) were analyzed. The fat content of KNC WD breast meat was higher than that of KNC HH. The breast and thigh meats of KNC HH had higher $L^*$ and $a^*$ values than the broiler or the KNC WD. WD meats showed greater DPPH radical scavenging activity and higher pH values than the HH. For the fatty acid composition, there was no significant difference in total content of the saturated fatty acids among chicken breeds (p>0.05). KNC had greater content of polyunsaturated fatty acids, especially arachidonic acid (20:4) and DHA (22:6), compared with the broiler. KNC WD meats had higher composition of linolenic acid (18:3) than the KNC HH. For sensory evaluation, the WD breast meat showed higher taste and tenderness scores than the HH. On the other hand, the soup made by broiler had higher taste scores than the KNC. The breast and thigh meat from two KNC breeds showed different quality parameters that may come from the differences of genetic attributes, feed, and production strategy between two breeds.

The methanolic (MeOH) extract of A. fruticosa bark, which showed immune-regulatory activities, was separated to purify an active compared by means of a multi-stage column chromatography. This resulted in the isolation and characterization of an isoflavone glycoside named 4', $6-Dimethoxyisoflavone-7-O-{\beta}-D-glucopyranoside$. Immuno-regulatory activities of the crude extract of Amorpha fruticosa LINNE bark were compared with that of an isoflavone glycoside (4', $6-dimethoxyisoflavone-7-O-{\beta}-D-glucopyranoside$). The crude methanolic extract of A. fruticosa and purified single compound showed 16% of relatively low cytotoxicity at a maximum concentration of 1.0 g/L in cultivated normal human lung cell line (HEL299). Cell growth of human T cells was increased up to 15%, 0.5 g/L of the crude extract added group. This was higher than a single compound added one. On the other hand, specific production rates of IL-6 and $TNF-{\alpha}$ from T cell were higher in the purified compound treat group ($0.82{\times}10^{-4}\;pg/cell$ and $1.08{\times}10^{-4}\;pg/cell$, respectively), compared to 0.5 g/L of the crude extract added group ($0.65{\times}10^{-4}\;pg/cell$ and $0.84{\times}10^{-4}\;pg/cell$, respectively). In addition, the growth of NK-92MI cells incubated with the crude extract was higher up to 56% over the cells grown with a single compound (0.5 g/L). In overall, the crude extract showed relatively higher immuno-regulatory activities compared with a single compound, probably due to the synergic effect given by other substances existed in the crude extract. Even though the siolated compound stimulated higher secretion of cytokines from human T cells.
