Objectives : The researcher investigated the anti-obesity effect of Platycodi Radix (P), Platycodi Radix and Cyperi Rhizoma combination water extract (PC) in mice fed a high fat diet and focused on the analysis of local area adipose tissue.Methods : Male ICR mice were divided into four groups, which were fed either a normal AIN diet (N group), a high fat diet (HFD group), or a high fat diet and orally administration with a concentraion of 300 mg/kg body weight (P group or PC group) for eight weeks.Results : Compared to mice in the HFD group, mice in the P group or PC group showed significant reductions in weight gain and relative weight of total fat. Compared to mice in the HFD group, mice in the P group showed significant reductions in relative weight of liver. In blood biochemistry analysis, AST, ALT, triglyceride, total-cholesterol and low density lipoprotein(LDL)-cholesterol, AI levels of P group or PC group were significantly lower than those of the control group AI. But serum serum high density lipoprotein(HDL)-cholesterol levels from the P group or PC group were significantly higher than those of the HFD mice in serum. And serum adiponectin levels from the P group or PC group were significantly increased that those of the HFD mice. And adipocyte number in the fat tissue from the P group or PC group was significantly higher than those of the HFD mice.Conclusions : Platycodi Radix, Platycodi Radix-Cyperi Rhizoma have an anti-obesity effect in mice and the effect is mediated by inhibition of fat gain.

The purpose of this case-control study was to show the relationship between risk factor(Sex, Age, Martial Status, Educational Periods, Family history, Variables of Obesity, Smoking Status, Drinking Status, Past History, Blood Test) and the incidence of stroke. Methods: 788 stroke patients were enrolled as the case group and 450 non-stroke patients as control group from Sep.2006 to Dec.2010. Patients were hospitalized within 30 days after the onset of stroke. Risk factors and warning signs were obtained from personal interview by oriental medicine doctors who used CRF. Results: 1. Age was found to have significant relation with stroke(p<.0001). 2. Martial status(p<.0001, OR=0.44) and educational periods(p<.0001) were both significant risk factor for stroke. 3. As a result of reviewing the influence of family history, it was found to have no significant relation with stroke. Stroke was found to have significant relation with stroke(OR=1.50). 4. Female waist circumference(WC, p<.0001) and female waist-hip circumference ratio(WHR, p<.0001) were risk factors for stroke. On the other hand, male WC and male WHR showed no significant influence on stroke occurrence as an independent risk factor. 5. Both smoking status(p<.0001, current smoker OR=8.95) and drinking status(p<.0001, current drinker OR=2.50, former drinker OR=2.82) were significant risk factors for stroke. 6. As a result of reviewing the influence of past history, transient ischemic attack(p<.0001, OR=8.46), hypertension(p<.0001, OR=4.72), hyperlipidemia(0.0064), diabetes mellitus(p<.0001, OR=3.34), stroke(p<.0001, OR=50.26) were significant risk factors. On the other hand, ischemic heart disease(p=0.2332) was found to have no significant relation with stroke. 7. Increase of WBC, RBC, Platelet, TG, FBS and Cl- level were significant risk factor of stroke, On the other hand, decrease of Hgb, Hct, AST, HDL-chol, LDH, Na+ and K+ level were significant risk factor of stroke. T-chol and ALT level showed no significant influence on stroke occurrence.

Single-and repeated-dose toxicities of Compound K (CK) were evaluated according to Toxicity Test Guidelines of Korea Food and Drug Administration using Sprague-Dawley rats. For single-dose toxicity study, CK was dissolved in drinking water, orally administered and examined for 14 days. As results, CK up to a dose of 5,000 mg/kg, the limited dose, neither induced death, clinical signs and necropsy findings, nor affected body weight gain and organ weights, in which 10% lethal dose could not be estimated. Based on the results of single-dose toxicity test, CK was administered at doses of 500, 1,000 or 2,000 mg/kg for 28 days for the evaluation of repeated-dose toxicity. All doses including the limited dose (2,000 mg/kg) of CK did not cause any abnormalities of rats, including mortality, clinical signs, body weight gain, feed/water consumption, necropsy findings, organ weights, hematology, blood biochemistry. Rather, high doses (1,000 - 2,000 mg/kg) of CK reduced the serum levels of alanine transaminase (ALT), aspartate transaminase (AST), creatinine phosphokinase (CPK), lactate dehydrogenase (LDH) and triglycerides, in addition to an increase in glucose, indicative of protective effects on hepatic and muscular injuries. Thus, both maximum tolerable dose (MTD) and no observed adverse effect level (NOAEL) were not determined. The results indicate that long-term intake of high-dose CK might not induce general adverse effects.

Behavioral and physiological responses of juvenile red seabream (Pagrus major) to different concentrations of ethanol were investigated. No swimming and no reaction to touching by a wooden stick was observed at 0.6% ethanol group in behavioral response, and survival rate was 100% after 5 hours of treatment. Red blood cell count, hematocrit and hemoglobin levels in plasma were not significantly different among all groups. AST activities in plasma significantly decreased as ethanol concentration increased. On the contrary, ALT activities in plasma significantly increased as ethanol concentration increased. Cortisol level in plasma was the lowest in 0.6% ethanol group. Glucose levels in plasma increased significantly when ethanol concentration increased more than 0.4%. Oxygen consumption of fish in 0.6% ethanol seawater was constantly lower than that of fish in control seawater from 2 hours after the exposure to ethanol seawater until the end of experiment.

The effects of sparp changes of water temperature (WT) on the stree response and physiological change of the cultured olive flounder (Paralichthys olivaceus) were examined by manipulating WT (3 patterns) in a running seawater culture system. In the first group (Exp. I), the WT was decreased from 18$^{\circ}C$ to 11$^{\circ}C$ within 6 hours and increased back to the original WT quickly. WT was decreased from 2$0^{\circ}C$ to 11$^{\circ}C$ within 5 hours and main-tained at 11$^{\circ}C$ for 10 hours. and then increased to 2$0^{\circ}C$ in the second group (Exp. II). In the third group(Exp. III) WT was decreased to 11$^{\circ}C$ within 5 hours (type A) or 10 hrs. (type B). In Exp. I and III, the level of serum cortisol was increased from 2.5$\pm$0.3 ng/ml and 2.6$\pm$0.9 ng/ml to 13.6$\pm$3.0 ng/ml and 12.4$\pm$3.2ng/ml, respectively, with WT decrease. However, no consistent tendency in the change of serum glucose level was shown according to WT decrease. In Exp. III, the glucose level of fish in type A was decreased until 5 hours and increased at 7 hours, then decreased until 12 hours where as the glucose level in type B was decreased until 5 hours and stayed at the level of 15.7 mg/dl. The serum osmolality was reduced with WT decrease and the response of serum electrolytes in this experiment conflicted, and a tendency in total protein, AST and ALT was not found following WT decrease. In conclusion, olive flounder responded to the stress caused by WT decrease and acclimated to this condition when the lower temperature was maintained. But there was no stress response in the blood of olive flounder when WT was increased. On the other hand, the degree of stress response in olive flounder was various according to the range and gradient of WT change.

This study examined the anti-diabetic effects of young barley leaf powder in rats with streptozotocin (STZ)-induced diabetes. Male Sprague-Dawley rats were divided into the non-diabetic (N) and diabetic groups, and fed the following for four weeks. The diabetic groups were further subdivided into three experimental groups: a diabetic control group (STZ), a diabetic group fed 5% barley leaf powder (STZ-BL), and a diabetic group fed 10% barley leaf powder (STZ-BH). Food and water intakes were higher in the diabetic groups than in the N group. Body weight gain was higher in the STZ-BL and STZ-BH groups compared with the STZ group, but there were no significant changes in body weight gain between the diabetic groups. The serum glucose and fructosamine levels were lower in the STZ-BL and STZ-BH groups than in the STZ group. The levels of serum insulin were higher in the STZ-BL and STZ-BH groups than in the STZ group. Serum ALT, AST and ALP activities decreased in the STZ-BL and STZ-BH groups compared with the STZ group, but there was no difference. These results indicate that dietary supplementation of barley leaf powder can attenuate clinical symptoms of diabetes in rats with STZ-induced diabetes.

In this study, the 4-week oral toxicity and anti-cancer activity of the hexane layer of Melia azedarach L. var. japonica Makino's bark extract were investigated. We carried out a hollow fiber (HF) assay and 28-day repeated toxicity study to confirm the anti-cancer effect and safety of the hexane layer. The HF assay was carried out using an A549 human adenocarcinoma cell via intraperitoneal (IP) site with or without cisplatin. In the result, the 200 mg/kg b.w of hexane layer with 4 mg/kg b.w of cisplatin treated group, showed the highest cytotoxicity aginst A549 carcinoma cells. For the 28-day repeated toxicity study, 6 groups of 10 male and female mice were given by gavage 200, 100, or 50 mg/kg b.w hexane layer with or without 4 mg/kg b.w of cisplatin against body weight, and were then sacrificed for blood and tissue sampling. The subacute oral toxicity study in mice with doses of 200, 100, and 50 mg/kg b.w hexane layer showed no significant changes in body weight gain and general behavior. The cisplatin-treated group significantly decreased in body weight compared to the control group but regained weight with 100 and 200 mg/kg b.w of hexane layer. The biochemical analysis showed significant increase in several parameters (ALT, total billirubin, AST, creatinine, and BUN) in cisplatin-treated groups. However, in the group given a co-treatment of hexane layer (200 mg/kg b.w), levels of these parameters decreased. In hematological analysis, cisplatin induced the reduction of WBCs and neutrophils but co-treatment with hexane layer (100 and 200 mg/kg b.w) improved these toxicities caused by cisplatin. The histological profile of the livers showed eosinophilic cell foci in central vein and portal triad in cisplatin treated mice. These results show that hexane layer might have an anti-cancer activity and could improve the toxicity of cisplatin.

Hepatic fibrosis is one of chronic liver diseases which spread in worldwide and it has high risk to turn advanced cirrhosis and hepatocellualr carcinoma. Brassica family has been produced for commercial purpose and in Korea Brassica rapa (Turnip) is cultivated in Ganghwa County, Gyeonggi-do Korea and used for making Kimchi. Recently pharmacological effects of turnip have been known; diabete mellitus modulation, alcohol oxidization, and fibrosis inhibition. In previous study we found antifibrogenic effect of turnip water extract and in this study we made turnip nanoparticle to promote turnip delivery into liver. At the same time we assessed the biological safety of turnip nanoparticle. Thioacetamide (TAA) induced hepatic nodular formation and fibrosis (mean of fibrosis score: 4). However, 1% turnip nanoparticle inhibited TAA-induced hepatic nodular formation and fibrosis (mean of fibrosis score: 2-3). Activities of serum enzymes (aspartic acid transaminase (AST), alanine transaminase (ALT), and total bilirubin (T-Bil)), complete blood count (CBC), and the appearance of organs were not different from control and 1% turnip nanoparticle treatment. Conclusively 1% turnip nanoparticle significantly reduced TAA-induced hepatic fibrosis and was safe in 7-weeks feeding.

Background: Herbal medication is widely used in the Korean Medicine Hospital, and drug-induced liver injury (DILI) in Korea has increased proportionally. Herb-induced liver injury now accounts for approximately 40% of cases of hepatotoxicity in Korea, according to research data. Currently, however, the component responsible for the toxicity is usually unknown or can only be suspected. Objective: To study the hepatotoxicity of Cheongsimyeonja-tang in DILI. Methods: A retrospective review was conducted of 82 inpatients between April 2010 and March 2017 with suspected drug-induced liver injury (n=5). The standard criteria (RUCAM scale) for drug-induced liver injury (DILI) were applied. The electronic medical records (EMRs) were retrospectively reviewed to identify the relevant database. Aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total bilirubin (T. Bili) were analyzed in blood samples before and after the administration of Cheongsimyeonja-tang. Results: Five cases out of 82 patients had a criterion-referenced probable (RUCAM) score ranging from 6 to 8 points DILI. However, statistical analysis of the liver function parameters results of the 82 patients did not show a statistically meaningful elevation after taking Cheongsimyeonja-tang. Conclusions: These data suggest a relationship between Cheongsimyeonja-tang and DILI. More studies are needed to validate these observations and to explore their implications.
