  • To study the effects of diets containing red Ginseng, rats were fed diets containing various amounts of red Ginseng for 10 weeks. The Ginseng diets were 600 mg of red Ginseng extract concentration, 1,200 mg of red Ginseng powder, 6,000 mg of red Ginseng tea, 3,000 mg of red Ginseng extract concentration, 6,000 mg of red Ginseng extract concentration, 12,000 mg of red Ginseng extract concentration per Kg of diet, and control. As results, growth rate, feed efficiency ratio, organ weight, and hematocrit value showed no statistically significant differences between red Ginseng fed animals and the controls. Serum cholesterol level and GPT were slightly lower in the experimental animals than those in the controls. These differences, however, were not statistically significant. Serum GOT activities for all experimental animals showed no statistically significant except for Group fed with 6,000 mg of red Ginseng extract concentration per Kg diet. This Group revealed significantly lower GOT activities than those of the controls statistically. No abnormalities of liver, spleen, and kidney were observed in the experimental animals.

  • This study was carried out to investigate the teratological potential of azinphos-methyl in the rat fetuses and to establish the nature of the effects on organogenesis and intrauterine development. The Sprague-Dawley female rats (180-210g) without previous litter were used in this study. Azinphos-methyl dosages of 0.094mg/kg, 0.4mg/kg, 1.5mg/kg were selected based on the acute intragastric $LD_{50}$ of 15mg/kg in the rat. Azinphos-methyl in water (Treatment Group), non-treatment control (Negative Control), water control (Sham Control), were administered by oral route and aqueous solution of acetyl salicylic acid (Positive Control) was administered by gavage at rate of 10 ml/kg of body weight from day 6 through 15. The results obtained were summarized as follows. 1. Decreased body weight of dams was observed in animals treated with aspirin and azinphos-methyl 1.5 mg/kg from day 7 through 14. (P<0.01) 2. There was an apparent decrement in the absolute liver weight in the azinphos-methyl 1.5 mg/kg treated group (P<0.05). However, the absolute and relative kidney weight in aspirin group (P<0.05, P<0.01) and the absolute and relative ovary weight in aspirin, azinphos-methyl treatment groups (P<0.01, P<0.05) were increased. 3. Decreased protein contents of dam's liver was observed in the aspirin and high dose azinphos-methyl treated group of animals (P<0.01). 4. The number of male-female ratio per dam increased in azinphos-methyl 1.5 mg/kg group but there was an apparent decrement in the body weight of fetuses in aspirin and high dose azinphos-methyl group (P<0.01, P<0.05). Total immature and resorbed fetuses were increased in aspirin group and the number of dead fetuses were also increased in azinphos-methyl 1.5mg/kg treated group of animals. (P<0.01, P<0.05). 5. In soft tissue defects, diaphragmatic hernia in diaphragm, anophthalmia, enlarged olfactory bulb, hydrocephalus, absence of third and lateral ventricle in skull, hydronephrosis in kidney, atrophy of left ventricle wall, enlarged apex in heart were observed. Especially, defects of diaphragm, heart and eye ball showed peak incidences in the high dose azinphosmethyl and aspirin group. (P<0.01). 6. Variations in the ossification patterns of skull, sternebrae, tail, forelimbs and hindlimbs showed peak incidences in the aspirin and high dose azinphos-methyl group. (P<0.01). 7. In the developmental indices of offspring, the mortality of aspirin and azinphos-methyl 1.5mg/kg treated group was higher than that of negative control. And, there was an apparent decrement in the body weight of fetuses (P<0.01) and considerable differences were obtained in pivoting, development of fur, auditory function, vision, quadrupled muscle development and testes descent in aspirin and azinphos-methyl 1.5mg/kg group. (P<0.01).

  • This experiment was conducted to investigate the effects of dietary bacteriophage CP supplementation on growth performance, nutrient digestibility, blood profiles, visceral organ weight, meat quality and fecal microflora in broilers. A total of 340 1-d-old ROSS 308 broilers (mixed gender) with an initial average body weight (BW) of $41.14{\pm}0.17g$ were randomly allotted to 4 treatments with 5 replicate pens per treatment and 17 broilers per pen for 31 days. Dietary treatments were: 1) CON, control diet, 2) CP05, CON + 0.05% bacteriophage CP, 3) CP10, CON + 0.10% bacteriophage CP and 4) CP15, CON + 0.15% bacteriophage CP. During d 15 to d 31, broilers fed CP15 diet had higher (P<0.05) body weight gain and feed intake than broilers fed CON diet. Overall, body weight gain in CP10 and CP15 treatment groups was greater (P<0.05) than that in CON treatment and feed intake was higher (P<0.05) in CP15 treatment than that in CON. Apparent total tract nutrient digestibility and blood characteristics did not differ (P>0.05) among treatments. The water holding capacity of breast meat increased (P<0.05) in broiler fed the diets containing bacteriophage CP compared with those fed the CON diet. Other meat characteristics such as pH value, breast muscle color ($L^*$, $a^*$, $b^*$) and drip loss were unaffected by dietary supplementation of bacteriophage CP. The weight of bursa of Fabricius increased (P<0.05) in CP05 when compared with CON. No significant difference was observed (P>0.05) among treatments in visceral weight and fecal microflora concentrations of Lactobacillus spp., Clostridium perfringens, Escherichia coli and Salmonella spp. In conclusion, dietary supplementation with 0.10 and 0.15% bacteriophage CP could improve the growth performance.

  • This research was performed to investigate the effect of Agarum cribrosum ethanol extracts on the levels of lipids in the serum of rats fed a high-fat diet for 10 weeks. Experimental groups were divided into basal diet only (BDG), high fat diet control (HFDCG), high-fat diet and 5% Agarum cribrosum ethanol extract powder (HF5S), and high-fat diet and 10% Agarum cribrosum ethanol extract powder(HF10S) groups. The levels of hematological variables were not significantly different among the four groups. Compared with the control group's serum total cholesterol level of 89.14 mg/dL, the levels of the HF5S and HF10S groups were significantly lowered to 77.26 and 75.47 mg/dL, respectively. Compared with the control group's LDL-cholesterol leve of 27.41 mg/dL, the LDL-cholesterol levels of the HF5S and HF10S groups were significantly lowered to 20.64 and 20.17 mg/dL, respectively. Also, compared to the control group's serum triglyceride level of 98.36 mg/dL, the triglyceride levels of the HF5S and HF10S groups were significantly lowered to 87.94 and 87.39 mg/dL, respectively. These results indicate that dietary intake of Agarum cribrosum ethanol extracts might have beneficial effects on obesity by reducing body weight and improving blood lipid profile.

  • We investigated the anti-obesity effects of small colored potato extracts by high pressure water extraction process on body weight, plasma lipid levels in high-fat diet-induced obese mice. Experimental groups were divided into basal diet only (Normal), high fat diet control (HFD), small colored potato water extracts (CP), and high-fat diet and small colored potato water high pressure extracts (HCP) groups. The levels of hematological variables were not significantly different among the four groups. Compared with the HFD group's serum total cholesterol level of $86.01{\pm}1.16mg/dL$, the levels of the CP and HCP groups were significantly lowered to $80.29{\pm}1.28$ and $77.21{\pm}4.21mg/dL$, respectively. Compared with the HFD group's LDL-cholesterol level of $18.92{\pm}2.44mg/dL$, the LDL-cholesterol levels of the CP and HCP groups were significantly lowered to $13.52{\pm}1.26$ and $12.93{\pm}1.26mg/dL$, respectively. Also, compared to the HFD group's serum triglyceride level of $82.71{\pm}3.94mg/dL$, the level of the HCP group was significantly lowered to $63.24{\pm}6.32mg/dL$. These results suggested that dietary supplementation of small colored potato extracts using high pressure water extraction does not have any adverse effects on the hematological variables, while improving the lipid content and reducing hepatic damage of the high-fat fed rats.

  • This study was performed to examine antitumor activities of Rubus coreanus Miquel and Angelica gigas Nakai extracts against sarcoma-180 and anti-stress activities in ICR mice. The variation of body weights of the 20 days of Rubus coreanus extracts-administrated mice group was very low. The survival rate (T/C %) of Rubus coreanus extract administrated group was 161% after 50 days from the inoculation of sarcoma-180 and the increment of their body weights was suppressed. Anti-stress effect of the extracts of R. coreanus and A. gigas were estimated by maeasuring blood chemical value and internal organs weight in ICR mice. The extracts of R. coreanus reduced the cholesterol and glucose to the normal level in the all stress animal models. The extracts of R. coreanus reduced the hypertrophy of the internal organs such as adrenal, spleen and liver to the regular level.

  • Type 2 diabetes mellitus (NIDDM) is a metabolic disorder that is characterized by high blood glucose in the context of insulin resistance and relative insulin deficiency. In order to control the type 2 diabetes mellitus, anti-hyperglycemic effect of Triticum aestivum L. water extracts (TAWE) was investigated in 7 week old male diabetic C57BL6/J-ob/ob mice. For the experiments, the diabetic animal model ob/ob mice and non-diabetic animal model lean mice were divided into 3 groups: non-treatment control group (Control), and two experimental groups orally treated with 25 or 100 mg/kg/day dose of TAWE (TAWE-25 and TAWE-100, respectively). The lean mice were used as the non-diabetic normal control. TAWE was orally administrated for 6 weeks and the diabetic clinical markers, including blood glucose level, body weight, organs weight and insulin level were determined. The oral administration of TAWE-100 in ob/ob diabetic mice significantly decreased blood glucose level (78.4%) and body weight (11.9%) compared with diabetic control group. The weights of organs, including spleen, liver, kidneys, heart and lung were not different among groups, while the treatments of TAWE-100 in ob/ob diabetic mice significantly reduced blood total cholesterol (24.35%) and triglyceride (23.97%) levels compared with the diabetic control group. The levels of serum insulin and glucose tolerance were improved after TAWE-100 treatment in ob/ob diabetic mice. Moreover, the immunohistochemical staining for insulin detection in pancreatic islet $\beta$-cells expressed high level of insulin in TAWE-100 treated ob/ob mice. From the above results, the intake of TAWE may be effective in anti-hyperglycemia by the attenuation of glucose and lipid levels. TAWE-containing diets or drugs may be beneficial for controlling diabetes mellitus type 2 in human.

  • In this work, the major flavonoid content of citrus peel ethanol extract and the changes in the serum lipid and body fat of high-fat-diet-fed rats were examined. The subjects were divided into four groups: the normal, control, O1 (0.1% citrus peel ethanol extract), and O5 (0.5% citrus peel ethanol extract) groups. The experimental groups (O1 and O5) were fed a high-fat diet mixed with 0.1 and 0.5% citrus peel ethanol extract, respectively, for 10 weeks. The results of the analysis showed that the main ingredients of the flavonoid in the citrus peel ethanol extract (60 brix) were $38.21{\pm}1.37$ mg/g hesperidin and $15.02{\pm}0.48$ mg/g narirutin. With regard to the changes in the serum total-cholesterol level, compared with the control group's $79.1{\pm}4.6$ mg/dL, the serum total-cholesterol levels of the O1 and O5 groups were significantly lowered to $64.6{\pm}5.4$ and $59.5{\pm}4.7$ mg/dL, respectively. As for the changes in the LDL-cholesterol level, compared with the control group's $18.4{\pm}3.7$ mg/dL, the LDL-cholesterol levels of the O1 and O5 groups were significantly lowered to $13.0{\pm}3.6$ and $13.0{\pm}1.9$ mg/dL, respectively. For the changes in the serum triglyceride level, compared with the control group's $74.5{\pm}13.2$ mg/dL, the serum triglyceride level of the O5 group was significantly lowered to $48.6{\pm}11.2$ mg/dL. Finally, with regard to the changes in body fat, compared with the control group, the 05 group showed a significant decrease. In conclusion, it was observed that citrus peel ethanol extract was effective in lowering the total-cholesterol, LDL-cholesterol, and triglyceride levels of high-fat-diet-fed rats.

  • The effect of fermented soybean culture of Bacillus subtilis MORI mixed with mulberry leaves on the lowering the levels of blood glucose and cholesterol was examined using neonatal streptozotocin-induced diabetic (n-STZ) rats. B. subtilis MORI produces 1-deoxynojirimycin (DNJ), an $\alpha$-glucosidase inhibitor. The content of DNJ of soybean fermented culture mixed with mulberry was higher (4.1$\pm$0.0 mg/g dry base) than that (1.5$\pm$0.0 mg/g) of mulberry. The concentration of 50% inhibition (IC50) against rat intestinal $\alpha$-glucosidase of soybean fermented culture mixed with mulberry was $5.6{\pm}0.1{\mu}g$/mL and that of mulberry was $17.0{\pm}0.5{\mu}g$/mL. Experimental groups of diabetic rats were randomly assigned to normal control group (NC group), diabetic control group (DC group) and three diabetic groups fed with DNJ food product. One of the three diabetic groups was M group (60 mg DNJ food product/kg) (DNJ food product containing 30% mulberry) and the other two were MM-60 group (60 mg/kg) and MM-120 group (120 mg/kg) (DNJ-fortified food product containing 30% fermented soybean culture mixed with mulberry leaves). The glucose in serum was significantly decreased in the MM-60 and MM-120 groups fed with DNJ-fortified food product for 4 weeks, compared with DC group. Total cholesterol and triglyceride in serum were also lower in MM-60 and MM-120 groups than the DC group. These results support that the fermented soybean culture of B. subtilis MORI mixed with mulberry leaves improved the metabolism of blood glucose and lipid in the n-STZ rat model.

  • 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.
