The purpose of this study was to investigate extract from mixed culture with Trichloloma matsutake mycelium in oriental medicine and cereal medium(OCM) to develop new material for pharmaceutical products and medicinal food for diabetes mellitus. To evaluate of hypoglycemic activity of OCM extracts, we examined the inhibitory activity of ${\alpha}$-glucosidasein OCM, blood glucose level and liver function of streptozotocin(STZ) induced diabetic rat. Experimental group was divided into 6 groups: first, it was divided into normal control group(hereafter NC group) and diabetes-induced group, and diabetes-induced group was subdivided into diabetic control group(DC group), treated by hot water extracts group(HE), ultra sonic waves, micro waves, and micro bubble extracts g roup(UE), crude polysaccharide of HE group (HEE) and crude polysaccharide of UE group(UEE) at a dose of 300mg/kg/body weight, respectively. In diabetic-induced groups, after streptozotocin was melted in 0.01M citrate buffer at 50mg/kg/body weight, when the non-fasting blood glucose levelwas 300 mg/dl or more in blood collected from the tail vein, it was regarded as diabetic induction and then such diabetic-induced experimental animals were used in this experiment. At the end of the experiment, blood glucose level increased by 4.19% in DC group but significantly decreased by 32.34%, 19.19%, 17.81% and 17.64%, respectively in UEEE, UE, HE, and HEE groups. In the cases of AST, ALT, and ALP, the experiment group treated with extracts showed significantly lowerblood glucose level than DC group. The levels of BUN and uric acid were found to be lower in the UMPM extract group(UE) than HW extract group(HE), which implies that herb medicine medium extracts in which Tricholoma matsutake mycelia were cultured are effective in reducing impaired liver function as well as high blood glucose level caused by diabetes. In addition, the administration of low temperature UMPM extracts was found to produce better results than that of high temperature hot water extracts. In this regard, it is expected that extracts from herb medicine obtained by cultivating Tricholoma matsutake mycelia will be widely used as new ingredients for foods and medicines for prevention and treatment of diabetes.

This study was conducted to determine the effect of grape by-product on milk yield, milk composition and blood metabolites of lactating cows. A total of 8 Holstein dairy cows (average age = 89.9 months, average lactation day = 164.4, Reproduction number = 2.8) were randomly allocated into control (no additives, CON) or grape by-product treatment (add 1 kg of grape by-product per day, GBP) for 3 weeks. The concentrations of fat, protein, lactose and total solid in milk were not affected by grape by-product supplementation. However, milk yield (23.13 vs. 21.16 kg/d) was higher (p<0.05) in GBP than in CON, while SCC was lower (p<0.05). The concentrations of glucose, alanine aminotransferase, total protein and BUN in blood did not differ between treatments. But blood aspartate aminotransferase and total cholesterol concentrations (123.75 vs. 95.34 IU/L, 200.82 vs. 180.63 mg/dl) were higher (p<0.05) in cows fed GBP than CON. As the result, grape by-product, which has a various potential benefits, could be used as a functional diet supplement for lactating dairy cows.

Objectives : The present study was designed to evaluate the protective effect of Allium tuberosum (AT) extract on atherosclerosis in LDL receptor knockout (LDLr KO) mouse fed western diet.Methods : The AT was extracted 70% ethanol. The experimental groups were divided with four groups of LDLr KO mice, one group fed a normal diet and the others fed a Western diets for 8weeks. Two Western diet groups were orally administered AT extract at dosage of 100 and 300 mg/kg body weight. The body weight and food intake were measured every day. We measured levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and Glucose in serum. Also, effect of AT extract performed using H&E staining.Results : The AT treatment groups showed decrease in body weight and food efficiency in comparison with control group. Blood biochemistry parameters such as TG, TC, LDL, and glucose levels were increased in control group, while AT treatment groups were reduced. Also, the increased levels of ALT and AST were improved by AT extract. We confirmed that the weights of liver, kidney, subcutaneous fat, epididymal fat, kidney leaf fat, and intraabdominal fat were change in LDLr KO mice treated AT extract. In addition, histopathological changes in liver and aorta were similar to normal group.Conclusions : Based on these results, the AT extract is considered to make prevention of atherosclerosis through reduction and functional improvement of the liver and vascular endothelial cells in the body fat accumulation and lipid content in LDLr ko mouse model.

Objectives : This study was performed to investigate the analgesic effect of Styrax japonica pharmacopuncture on formalin induced pain in rats and to figure out efficient extraction method. Methods : The subjects were divided into 5 groups ; normal group(treated with normal saline at KI03, and injected normal saline at right hindpaw after 35 minutes), control group(treated with normal saline at KI03, and injected with formalin at right hindpaw after 35 minutes), water group(treated by hot water extraction pharmacopuncture at KI03, and injected with formalin at right hindpaw after 35 minutes), ethanol group(treated with ethanol extraction pharmacopuncture at KI03, and injected with formalin at right hindpaw after 35 minutes), and ultrasound group(treated with ultrasound extraction pharmacacupuncture and injected with fromalin formalin at right hindpaw after 35 minutes). We conducted a formalin test with ultrasonic vocalization( USV), and after the test checked for substance P, Aspartate aminotransferase(AST), and Alanine aminotransferase(ALT) concentration in the blood for each of the groups. Results : There was a significant analgesic effect of Styrax japonica pharmacopuncture in the early phase of the formalin test, and pharmacopuncture made with an ultrasound extracting method was observed to have a better analgesic effect than other extracting methods in early phases. The substance P concentration decreased significantly in the Styrax japonica pharmacopuncture treated group and no difference was found in the AST and ALT concentration of each group. Conclusion : These results demonstrated that Styrax japonica pharmacopuncture had analgesic effects in noxious nociceptors stimulation. Also pharmacopuncture made with an ultrasound extracting method had a better analgesic effect than others.

Objectives: The present study was carried out to investigate the effects of YJT on experimental hypothyroidism induced by sodium perchlorate and methimazolein in mice. Methods: 30 one-month-old C57BL6 mice were decided into 4 groups: 1) normal (n=6), 2) sodium perchlorate and methimazolein-induced hypothyroidism control (n=8), 3) hypothyroidism mice treated with low YJT (n=8), 4) hypothyroidism mice treated with high YJT (n=8). Sodium perchlorate and methimazolein were administered for 4 weeks, YJT (low and high) was administered for 2 weeks after sodium perchlorate and methimazolein were initiated for a total duration of 2 week. The changes were observed : weight of body, T3, T4, TSH, follicular cells in the thyroid tissues, LDL cholesterol, HDL cholesterol, triglyceride and free fatty acid, FBG, AST, ALT and so on. Results: YJT did not affect body weight gain. YJT restored free T4 level decreased by sodium perchlorate and methimazolein and prevented shrinking of follicles and proliferation of follicular cells in the thyroid tissues. In addition, YJT lowered total and LDL cholesterol levels elevated by sodium perchlorate and methimazolein respectively and ameliorated distribution of fat in liver tissues. In addition, the effect on fasting blood glucose (FBG), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were also investigated. Conclusions: These data suggest that YJT can be used to treat woman patients which are accompanied with hypothyroidism relatively safely.

Hepatic ischemia-reperfusion injury (HIRI) is linked with high mortality rate. Several agents have been developed so far to reduce the risk of HIRI. In this study, we investigated the effects of combined treatment of Ginko biloba leaves extract and vitamin C (GLEVC) on hepatic ischemia-reperfusion injury. To explore the protective effects of GLEVC on HIRI rats model were tested. After the development of HIRI by using clamping method rats were then randomly divided into four groups. Different doses of GLEVC were administered in HIRI rat model. The level of ALT, AST, SOD and MDA content in serum were detected in HIRI groups. Moreover, the activity of SOD, content of MDA, and GSH in hepatic tissue were also examined. Bcl-2 and Bax protein expression were detected by immunohistochemical staining method. Compared with sham group, GLEVC has the protective effect on the HIRI-induced model. Level of ALT, AST, and MDA in blood were significantly lower in GLEVC group compared with HIRI-induced group. Moreover, SOD activity and GSH were increased in GLEVC group whereas MDA content was reduced by GLEVC treatment. Furthermore, HIRI-induced Bax protein was reduced upon GLEVC treatment, whereas Bcl-2 protein expression was enhanced. These results demonstrate that GLEVC treatment may provide potential ameliorative therapy by reducing damaged signaling mechanism in hepatic ischemia/reperfusion injury model.

Although transfusion of blood and plasma products are accepted as the principle means of transmission of HCV, other parenteral methods, such as acupuncture, tattooing needles, piercing, and surgery are possible methods of transmission of HCV. We managed a case of chronic hepatitis C acquired through ear piercing and acupuncture. A 10-year old girl presented with nausea, abdominal pain, and anorexia for 1 month. Her laboratory finding showed the following: AST/ALT, 865/1,290 IU/L; positive anti-HCV Ab; and HCV RNA. One year previously, she was treated with acupuncture for an ankle sprain and 2 years previously, she had her ears pierced. Laboratory findings of family members showed AST/ALT in the normal ranges, and negative anti-HCV Ab and HCV RNA. The pathologic findings of a liver biopsy revealed chronic hepatitis with mild lobular activity, moderate porto-periportal activity, and portal fibrosis. She was treated with pegylated interferon ${\alpha}$-2a and oral ribavirin for 6 months, after which the clinical symptoms and laboratory findings improved.

This study investigated the protective effects of ethylene glycol-bis(${\beta}$-aminoethyl ether)-N,N,N',N'-tetraacetic acid (EGTA), an extracellular calcium chelator, and ethylenediaminetetraacetic acid (EDTA), which chelates calcium and most metal ions, against carbon tetrachloride ($CCl_4$)-induced acute hepatotoxicity in mice. Mice were treated with EGTA or EDTA at a dose of 20 (low) or 100 mg/kg (high) subcutaneously 1h before $CCl_4$ administration. The mice were fasted and sacrificed 18h after $CCl_4$ treatment. Blood samples were collected from the carotid artery by decapitation under light ether anesthesia. Serum alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride (TG), and cholesterol levels were measured. Malondialdehyde (MDA) production was determined as an index of lipid peroxidation in the liver. The liver, kidneys, and spleen were weighed. We also evaluated the histopathological changes in the liver in each group. The relative weights of the liver were significantly higher in the $CCl_4$-treatment group than in the normal group, except in the high-EDTA treatment group. EGTA and EDTA treatment caused a significant decrease in serum ALP, ALT, and AST levels. Of all of the doses of EGTA and EDTA tested, the high-EDTA dose resulted in the most remarkable inhibitory action. The protective effect in the high-EDTA-treatment group was confirmed histopathologically. The low-EGTA-treatment group showed a significant decrease in serum TG and cholesterol levels. Liver MDA levels were significantly decreased in the EGTA (20 mg/kg) and EDTA (20, 100 mg/kg) groups. These results suggest that EDTA, which chelates both calcium and metal ions, confers better protection in $CCl_4$-induced acute liver damage than does EGTA, a calcium chelator.

In this research, as a method for verifying the efficacy of Ssangwhatang and fungus-fermentated Ssangwhatang, a comparative study on the liver protection effect was conducted using animal experiments by inducing the liver toxicity with the $CC_{l4}$ treatment. Inducing the liver damage resulted in the increase in the serum AST and ALP activity, and one day administration of the test material($CCI_4$: 0.5 ml/kg/day) caused 520 IU/L of the ASP activity leading to 29% enhancement in comparison with the normal group and 93% and 81% reductions in the fungus-fermentated Ssangwhatang-administered groups, BFST1 and BFST2, respectively. ALT is 42 IU/L for the normal group and 99 IU/L for the negative control group leading to 135% enhancement. 15 ml/kg/day and 30 ml/kg/day administrations of fungus-fermented Ssangwhatang(BFST) resulted in 51% and 45% decreases in the ALT concentration, respectively. One day administration of 30 ml/kg Ssangwhatang and fungus-fermentated Ssangwhatang caused the LDH in the plasma to tend to decrease. $CCI_4$(1.0 ml/kg/day) administered at the 0th and 4th days led to the observation of the tendency toward the decrease in AST, ALT, and LDH contents. The results indicate that the function of Ssangwhatang is partly reinforced under the fungus-fermentated Ssangwhatang performed in order to verify the efficacy of Ssangwhatang' s effect on the recovery from fatigues.

Objectives : Herba on lipid levels in serum and lipid accumulation in liver tissue in high fat diet-induced hyperlipidemic mice. Methods : Experimental groups were subdivided into four; Normal diet group (Nor), Hyperlipidemic mice (Con), Lysimachiae Herba water extract administered mice (LWE), Lysimachiae Herba methanol extract administered mice (LME). Thereafter the changes in body weight, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, AST, ALT, fasting blood glucose in serum were measured. In addition histopathological changes in liver tissue was also observed. Results : Body weight, AST and ALT were not affected by the administration of water or methanol extracts of Lysimachiae Herba. However, methanol extracts of Lysimachiae Herba down regulated the total cholesterol and triglyceride in high fat diet - induced hyperlipidemic mice. Conclusions : In this study, results of total cholesterol and triglyceride showed significant effect in LME compared with LWE, but other results didn’t. Therefore, it is necessary to have more study of Lysimachiae Herba to apply hyperlipidemia.
