  • In order to find out physiological effects of diets supplemented with seamustard (Undaria pinnatifida) on the growth, survival rate, body compositions and blood properties of young rockfishes (Sebastes schlegeli) in range of average total length from $2.99{\pm}0.23\;cm\;to\;18.52{\pm}1.07\;cm$ and average body weight from $1.03{\pm}0.18\;g\;to\;120.64{\pm}19.32\;g$, experiments were performed for 140 days by feeding four experimental diets supplemented with $0\%,\;3\%,\;5\%\;and\;7\%$ of seamustard powder. In addition, the tests on tolerance of the fishes against low $O_2$ saturation and starvation were carried out after the feeding experiments. The fishes fed diet supplemented with $5\%$ of seamustard powder revealed the best results in growth of total length and body weight. Crude lipid content in the whole viscera of fishes fed diets supplemented with seamustard powder was higher than that of fishes fed diet without seamustard powder, while the moisture, crude protein, crude lipid and crude ash composition in the dorsal muscle did not show any remarkable differences among diet groups with or without seamustard powder. Hematocrit and mean number of red blood cell in fishes fed diets supplemented with seamustard powder was elevated, despite of no notable changes in mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration. The resistance of the fish to low $O_2$ saturation was elevated by feeding seamustard powder. Upon the starvation of fish for 31 days after the feeding experiments, body weight loss of three groups fed diets with seamustard was smaller compared with the group fed diet without seamustard.

  • When fed on one of the six isonitrogenous (45%) and isolipic (8%) feed containing 5 or 10% Undaria, 2% wasabi leaf, 2% wasabi stem and 0.5% herb (Obosan) for a period of 8 weeks, 95-98% juvenile flounder survived. Growth, feed efficiency and condition factor of the flounder fed on diet containing 0.5% herb were significantly (p<0.05) higher than those fed on diet supplemented with 10% Undaria. There was no significant (p>0.05) differences in moisture, crude protein, lipid and ash of the flounder receiving the different diets. The flounder fed on diet supplemented with 10% Undaria had the highest moisture but the lowest lipid in liver. Hematological parameters such as red blood cell, hematocrit and hemoglobin and serum constituents such as glucose, total cholesterol and glutamic-oxaloacetic transaminase of the flounder fed on the diets varied but no specific trend became apparent. Lysozyme activity in the serum of the flounder fed on diet supplemented with 5% Undaria and the herb, as well as nitroblue tetrazolium (NBT) reduction of macrophage in the head kidney of the flounder fed on diet containing the herb and 2% wasabi stem were significantly (p<0.05) higher than those receiving control diet. Briefly, the herb supplementation promoted growth and that of Undaria and wasabi stem enhanced non-specific immune response.

  • This experimental study was carried out to evaluate the effects of Kimchi intake of Cordyceps sinensis extract (CDSE) supplementation on cytokine-induction and immune response in mice. To study in experiments using male Balb/c mice fed Kimchi and Kimchi of CDSE supplementation (addition of 2% of total Kimchi weight) containing fed experimental diet during 2 weeks. Experimental mice were fed control diet or diet containing freeze-dried Kimchi at the level of 5%(w/w) or 5% freeze-dried Kimchi with 2% CDSE supplementation. The main ingredient of Kimchi was Korean cabbage and fermentation was carried out at $4^{\circ}C$ for three weeks. Freeze-dried 2% CDSE supplementation was added to Kimchi at the beginning of fennentation. In order to investigate the effect of Kimchi intake of CDSE supplementation (5%Kimchi-2%CDSE), the following was performed; body weight, food intake, hematological parameter, serum level of mouse interleukin-4 (mIL-4) and mouse $interferon-{\gamma}$ $(mIFN-{\gamma})$, and, the percentage of CD3+/CD4+, CD3+/CD8+, B220+ in splenic cells. The results of final body weight, and food diet intake of two Kimchi groups were lower than those of the control group (not supplemented experimental diet). The hematology change obtained from the level of WBC (white blood cell) and platelet were not affected by feeding different dietary regiments, but the level of RBC (red blood cells) HB (hemoglobin), and spleen weight of two Kimchi groups were increased significantly than those of the control group. The serum level of IL-4 and $IFN-{\gamma}$ of two Kimchi groups were increased significantly than those of the control group, also enhanced the percentages of the CD3+/CD4+ and CD3+/CD8+ by 5% freeze-dried Kimchi, and 5%Kimchi-2%CDSE group were 43.9 and 60.1%, and 96.0 and 174% than those of the control group, respectively. From these results, it can be concluded that Kimchi itself has an immuno-stimulatory effect and Kimchi contaning 2% CDSE supplementation has the more pronounced effect in vivo system.

  • Objectives This study is designed to evaluate the safety of Bojungikgi-tang soft extract in healthy male volunteers. Methods 12 healthy male volunteers were recruited and this study was carried out by a single center. Laboratory test results, vital signs of the volunteers were collected to evaluate safety. According to registration order, the 12 subjects were allocated by serial number. To evaluate safety, blood samples were taken and vital signs were checked 4 times - screening, pre administration, post administration and follow up-during the whole trial. The difference between pre (before medication [0 hr]) and post-administration (after medication [48 hr]) variables was summarized as mean±standard deviation. The normality test was performed using the Kolmogorov-Smirnov test and Shapiro-Wilk test. When the normality is satisfied, the paired t-test is applied. Otherwise, the non-parametric method, Wilcoxon signed rank test is applied. The significance level was p<0.05. The incidence of all adverse effects are shown in percentage. Results In the case of red blood cell, hemoglobin, hematocrit, lymphocytes, neutrophils, protein, γ-glutamyl transpeptidase values, the normality test result of the variable for the difference value before and after the dosing has a significance level <0.05. But most of values did not deviate from the normal range, and the deviation from the normal range could not be regarded as the significance associated with this clinical trial. And adverse event wasn't observed associated with the clinical trial drug. Conclusions Bojungikgi-tang soft extract were considered to be safe for healthy male volunteers.

  • This study was conducted to investigate the effects of hot melt extrusion (HME) nano-iron as an alternative for the common ferrous sulfate on iron (Fe) bioavailability, growth performance, nutrient digestibility, intestinal morphology, and intestinal microbiota of weanling pigs. A total of 200 piglets (Landrace ${\times}$ Yorkshire ${\times}$ Duroc) were randomly allotted to seven treatments on the basis of initial body weight (BW) and sex. Treatments were the INO100 (100 ppm Fe as $FeSO_4$), HME-Fe levels (50, 75, and 100 ppm nano-Fe as $FeSO_4$). ORG100 (100 ppm Fe as iron methionine). In phase 1, the HME50 pigs showed the lowest Fe content in feed and feces. Plasma Fe concentration was increased in HME100 and ORG100 pigs. In phase 2, there were significantly lower concentration of Fe in feed and feces of HME50 pigs (p < 0.01). A lower Fe concentration in the plasma and liver were observed in HME50 pigs compared with HME100 pigs. Concentration of red blood cell (RBC) was the lowest (p < 0.01) for HME50 pigs. During phase 2, the HME100, HME75, and ORG100 pigs showed a higher RBC and hemoglobin values compared with HME50 pigs. Digestibility of gross energy (GE) and crude protein (CP) were significantly higher in HME100 pigs compared with HME50 pigs. There was an increased (p < 0.01) villus height in the duodenum and jejunum of HME100 pigs compared with HME50 pigs. It is concluded that dietary Fe does not improve growth performance of weanling pigs; however, increasing the dietary iron concentration in weanling piglets increased the RBC and hemoglobin. In addition, the potential ability of HME to be used at a lower level (HME75) was observed.

  • Urine sediments are performed by a microscopic examination of centrifuged urine by medical technologists. This study examined different urine sediment preparation procedures. The 107 fresh urine specimens that tested positive from white blood cells (WBCs) and red blood cells (RBCs) in the urine dipstick test and the cobas u 701 analyzer, respectively, were selected for manual microscopy. This study evaluated an automated urine sediment analyzer and three manual microscopy methods for WBCs and RBCs. The methods were performed according to the test guidelines. The coefficients of determination between the cobas u 701 analyzer and the Korean Association of Quality Assurance for Clinical Laboratory (KAQACL) for WBCs and RBCs were r2=0.977 and r2=0.970, respectively. The concordance rates between the cobas u 701 analyzer and KAQACL for WBCs and RBCs were 74.8% and 77.6%, respectively. A good correlation and concordance with the automatic analyzer were shown when the specimens were prepared and examined using the KAQACL method. Consequently, the differences in the urine sediment preparation procedures affected the sediment concentrations, influencing the cell number per high power field (HPF).

  • Purpose: There are various methods to diagnose hemangioma, such as ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI) and nuclear medicine. However, by development of SPECT imaging, the blood-pool scan using $^{99m}Tc$-labeled red blood cell has been used, because it was non-invasive and the most economical method. Therefore, in this study, we proposed that the usefulness of $^{99m}Tc$-RBC scan and SPECT of the head and neck to diagnose unlocated hemangiomas. Materials and Methods: $^{99m}Tc$-RBC scan and SPECT was performed on 6 patients with doubtful hemangioma (4 person, head; 1 person, neck; 1 person, another). We labeled radiopharmaceutical using modified in vivo method and then, centrifuged it to remove plasma. After a bolus injection of tracer, dynamic perfusion flow images were acquired. Then, anterior, posterior, both lateral static blood-pool images were obtained as early and 4 hours delayed. SPECT was progressed 64 projections per 30 seconds. Each image was interpreted by physicians, Nuclear medicine specialist, and technologist blinded to patient's data. Results: In 5 patients of all the radioactivity of doubtful site didn't change in flow images, but, in blood-pool, delayed and SPECT images, it was increased. So, it was a typical hemangioma finding. The size of lesion was over 2 cm, and it could discriminate as comparing to the delayed and SPECT imaging. On the other hand, in 1 patient, the radioactivity was increased in blood-pool images, but, not in delayed and SPECT images, so, it was proved no hemangioma. Conclusion: Using $^{99m}Tc$-RBC Scan and SPECT, we could diagnose the hemangiomas in head and neck, as well as, liver, more non-invasive, economical, and easy. Therefore, it considered that $^{99m}Tc$-RBC scan and SPECT would offer more useful information for diagnosis of hemangioma, rather than otherimaging such as US, CT, MRI.

  • The purpose of this study was to examine the radiation protection effect of protaetia brevitarsis larvae extracts known as antioxidant food. In this study 90 female rats were clssified in to 5 groups: NC Group, PBE Group, IR Group, PBE+IR Group and IR+PBE Group. In IR Group, 7 Gy of Co-60 gamma ray was irradiated to SD rat and protaetia brevitarsis larvae extracts were administered orally at 200 mg/kg once a day for 14 days. And then on the 1 day, 7 days, 21 days later after irradiation, changes in blood cell component, superoxide dismutase(SOD) activity, spleen index, histopathological evaluation of the ovary and uterus were observed. As a result, the PBE+IR Group (p<0.01, p<0.05) and IR+PBE Group (p<0.01, p<0.01) showed a significantly radiation protection than the IR Group in lymphocyte and red blood cell on the 21 days. It was also confirmed that SOD activity of PBE+IR Group (p<0.01) and IR+PBE Group (p<0.01) was significantly increased than the IR Group. In spleen index, PBE+IR Group (p<0.05) and IR+PBE Group (p<0.01) showed a significantly recovery than the IR Group. In histopathological observation, PBE+IR Group in the ovary and PBE+IR, IR+PBE Group in the uterus showed less inflammatory reactions of cystoplasm than the IR Group. Based on These results, It is judged that protaetia brevitarsis larvae Extracts have radiation protection effect against blood and reproductive. It is expected to be useful for research of radiation protection agent.

  • This experimental research has been done to study the effects of Bojungikgi-tang(BJIKT) on the anti-allergic reaction. We found the several important results from the research which has been performed by two experiments toward immediately type and delayed type in order to study the effects of BJIKT on hypersensitivity response to mice. The results obtained from our research are as following: 1. The survival rate of one group to which we injected only the compound 48/80 is almost 0% according to its density and timing test. In the other hand, the survival rates of the other group to which we injected both of the compound 48/80 and BJIKT are 20%, 10%, 30%, 10%, 40%, and 70% according to 0.025, 0.05, 0.1, 0.25 0.5 and 1(mg/g) of compound 48/80. Time dependency test also shows the 10% and 0% survival rates in 5 and 10 minutes. 2. BJIKT revealed the significantly inhibitory effect on Compound 48/80 induced Mast cell degranulation. 3. BJIKT showed the significantly inhibitory effect in the delayed type hypersensitivity response to picryl chloride. 4. BJIKT showed the significantly inhibitory effect in the delayed type hypersensitivity response to sheep red blood tell. Our research provides the important evidence that BJIKT is benificial to the prevention and treatment of allergy related diseases.

  • In order to search for anti-influenza virus type A agents from Korean medicinal herbs, we selected 100 medicinal herbs, based on a review of the Korean traditional medicine books. Four of 100 Korean medicinal herbs, MM-40, MM-55, MM-63, MM-110, exhibited very strong anti-influenza virus activity. The fractions of four medicinal herbs, which had very strong anti-influenza virus activity, were tested for antiviral activity by means of Haemagglutination inhibition test(HTT), 40% MeOH fraction of MM-40, $H_2O$ fraction of MM-55, 20% fraction of MM-63 3nd $H_2O$ fraction of MM-110 had strong anti-influenza virus activity at the range of $78{\mu}g/ml$ to $156{\mu}g/ml$, 1.56mg/ml to 100mg/ml, 6.25mg/ml to 50mg/ml and $48.7{\mu}g/ml$ to $780{\mu}g/ml$, respectively. These results of HIT indicated that fractions of Korean medicinal herbs might inhibit either attachment of virus to cell surface receptor or penetration of virus into cell during the initial stage of infection. In the cytotoxicity of fractions against red blood cells, 40% MeOH fraction of MM-40, 20% fraction of MM-63 and $H_2O$ fraction of MM-110 showed cytotoxicity at the range of $78{\mu}g/ml$ to 10mg/ml, 50mg/ml to 100mg/ml and $195{\mu}g/ml$ to 100mg/ml, respectively, whereas $H_2O$ fraction of MM-55 did not show cytotoxicity. In order to establish influenza virus adapted animal model, influenza virus type A were passaged 3 and 4 times successively in Balb/c mouse. As a result, we had 4 HA unit titers on the 5 days of 3rd passages and 7 days of 4th passages after infection, respectively.
