  • This study was conducted to investigate the application possibility of leaf and stem extract(LSE) extracted from mixture of leaf and stem of ginseng radix (Panax Ginseng C.A. Meyer). We conducted analysis of the ginsenoside content by HPLC. Also we investigate the effects of the LSE on the reduction of serum lipid and improvement of blood parameters in rats fed high fat diet 5 weeks. We examined by analyzing the serum total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride and atherogenic index and hematological datas and serum metabolic variables. Sprague-Dawley rat weigh $150\;g\;{\pm}\;15\;g$, were ramdomly assigned to 4 groups, basal diet only(BDG), high fat diet weithout LSE(FDCG), high fat diet and 10% LSE(FD10G), high fat diet and 20% LSE(FD20G). The result of this study were as follow. Hematological datas of 4 groups were same level, which were not significant. The activities of ALP, GOT and LDH level were significantly different. Total cholesterol, LDL-cholesterol, triglyceride contentrations in serum and atherogenic index were remarkably reduced in LSE supplemented groups as compared high fat control groups. These result imply that LSE could be used as possible for decrease of serum lipid concentration.

  • Renal dysfunction could be developed as the secondary disease of liver cirrhosis. Delayed or suppresed lipid peroxidation by the treatment with physiological active substances could be explained as the antioxidative and protective effect in tissue damage. In this study, we investigated an antioxidative effect and renal function improvement of Hovenia dulcis in liver fibrosis(cirrhosis) induced rats. The female Sprague-Dawley rats (180∼210 g) were divided into 3 groups (Normal, AC: CCl₄ mixture treated group, AC-HV: CCl₄ mixture+ Hovenia dulcis treated group) and renal damage was developed by CCl₄ mixture administration in 4 weeks (0.8 ㎖/rat). The tissue of kidney and liver and sera were used for quantitative measurement of enzyme activity, MDA and Hyp. The histological change and gene expression of collagen α1(III) mRNA and a1(IV) mRNA were observed by Masson's trichrome staining and RT-PCR. As a result, the clinical biochemical parameters of liver function (AST and ALT) in sera of AC-HV group showed significantly 46.4% and 104.8% lower (p<0.005), and the level of ALP and BUN as the parameter of protein urine and azotemia showed 17.8 % and 25.8 % lower than in AC group. In AC-HV group, the concentration of MDA in kidney and liver was decreased significantly 15.8% and 21.3% when compared with AC group (p<0.01 -0.005). The content of Hyp in kidney of AC-HV group is merely higher than in AC group, in contrast to liver tissue. The expression of collagen α1(III) mRNA and collagen α1(IV) mRNA was decreased in AC, but both of collagen mRNA in normal and AC-HV group expressed fast similar. More massive lipid droplets, thicker collagen fiber bundles in portal triads and more formation of portal central septum were observed in the liver of AC group than in AC-HV group. In conclusion, CCl₄ mixture intoxication could be developed not only liver fibrosis(cirrhosis) but also renal dysfunction by the massive lipid peroxidation and suppression of interstitial collagen and basement membrane collagen synthesis. And the water extract of Hovenia dulcis may be possessed the antioxidative and protective effect and improvement of kidney function in renal dysfunction induced rats.

  • Precipitation was formed during the preparation of decoction from a mixture of Scutellariae Radix and Coptidis Rhizoma or Phellodendri Cortex according to the prescription of Hwang-ryean-hae-dog-tang. Baicalin and berberine were identified in coprecipitated product and these components were the active ingredients of two herbal medicine. The coprecipitated product was very slightly soluble in water and sparingly soluble in ethanol. The stoichiometric ratio of baicalin and berberine was found to be 1:1. The lipid-water partition coefficients of coprecipitated product were increased more than baicalin and berberine in chloroform, but were decreased in other organic solvents. The content of baicalin and berberine in coprecipitated product, determined by HPLC, were 23.08% and 26.75%, but the content of active ingredients in supernatant were 0.66% and 0.26%, respectively. The dissolution profile of baicalin of coprecipitated product was increased more than extract of Scutellariae Radix in artificial gastric juice, but was decreased in artificial intestinal juice. The dissolution rate of berberine of coprecipitated product was lower than extract of Coptidis Rhizoma in artificial gastric juice and intestinal juice commonly.

  • Lindera obtusiloba has been used in traditional herbal medicine for the treatment of blood stasis and inflammation. The leaves of Lindera obtusiloba have been reported to exhibit various physiological activities. However, there is little information available on their antiplatelet and antithrombotic activities. Thus, the present study aimed to evaluate the effect of Lindera obtusiloba leaf extract (LLE) on platelet activities, coagulation and thromboembolism. In a platelet aggregation study, LLE significantly inhibited various agonist-induced platelet aggregations in vitro and ex vivo. Furthermore, LLE significantly inhibited collagen-induced thromboxane A2 (TXA2) production in rat platelets. In addition, oral administration of LLE was protective in a mouse model of pulmonary thromboembolism induced by intravenous injection of a mixture of collagen and epinephrine. Interestingly, LLE did not significantly alter prothrombin time (PT) and activated partial thromboplastin time (aPTT). This study indicates that the antithrombotic effects of LLE might be due to its antiplatelet activities rather than anticoagulation. Taken together, these results suggest that LLE may be a candidate preventive and therapeutic agent in cardiovascular diseases associated with platelet hyperactivity.

  • Objective : Reflux esophagitis is a disease caused by reflux of stomach contents, stomach acid, and pepsin into the esophagus, and is currently increasing worldwide. This study was conducted to evaluate the effect of a mixture of Rhei Rhizoma and Scutellariae Radix (RS) extract on acute reflux esophagitis in rats. Methods : Rats were divided into five groups for examination: Normal group (Nor, n=8), water-treated acute reflux esophagitis rats (Con, n=8), tocopherol 30 mg/kg body weight/day-treated acute reflux esophagitis rats (Toco, n=8), RS 100 mg/kg body weight/day-treated acute reflux esophagitis rats (RS100, n=8), RS 200 mg/kg body weight/day-treated acute reflux esophagitis rats (RS200, n=8). All rats fasted for 18 h and then were derived by linking the metastatic junction between pylorus and forestomach and corpus. And rats were sacrificed 5 h after surgery. We analyzed the expression of NADPH, MAPK, inflammatory, anti-inflammatory, and tight junction related proteins by western blot in esophageal tissue and observed the level of reactive oxygen species (ROS), alanine aminotransferanse (ALT), and aspartate aminotransferase (AST) in serum. Results : RS administration significantly protected the esophageal mucosal damage of reflux esophagitis, and ROS, AST, and ALT levels were significantly reduced in RS administration compared to Con group. In addition, RS administration effectively suppressed MAPK and NF-κB pathways and upregulated protein expressions of tight junction protein. Conclusions : These results suggest that RS protected the esophageal mucosa by inhibiting the MAPK and NF-κB pathways and upregulating tight junctions.

  • With the recent rapid improvement in the standards of life and westernization of dietary lifestyles, the consumption of high-calorie diets such as high-fat and high-protein red meat and instant foods has increased, while less vegetables containing dietary fiber are consumed. In addition to that, stress, erroneous dietary behaviors, and contaminated environments are linked to the risk of developing ulcerative colitis, which is on the rise. Another cause of ulcerative colitis is that involve laxative abuse, including repeated, frequent use of laxatives, and include such conditions as deteriorated bowel function, irritable bowel syndrome, diarrhea, intestinal inflammation, etc. The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and combination with herbal medicine on dextran sodium sulfate (DSS)-induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n = 9): group I-normal group, group II-DSS control group, group III-DSS + sulfasalazine (30 mg/kg), group IV-DSS + sulfasalazine (60 mg/kg), group V-DSS + sulfasalazine (30 mg/kg) + Radish Extract mixture (30 mg /kg) (SRE). DSS-treated mice developed symptoms similar to those of human UC, such as severe bloody diarrhea and weight loss. SRE supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SRE treatment significantly reduced the expression of pro-inflammatory signaling molecules through suppression both mitogen-activated protein kinases (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways, and prevented the apoptosis of colon. Moreover, SRE administration significantly led to the up-regulation of antioxidant enzyme including SOD and Catalase. This is the first report that Radish extract mixture combined with sulfasalazine protects against experimental UC via the inhibition of both inflammation and apoptosis, very similar to the standard-of-care sulfasalazine.

  • Objective : This study investigated the anti-diabetic effects of DM1, a herbal mixture with Atractylodis Rhizoma, Anemarrhenae Rhizoma, and Cinnamomi Cortex in high fat diet (HFD)-induced diabetic mice and the mechanism in C2C12 mouse skeletal muscle cells. Methods : The C57B/6 mice were fed high fat for 12 weeks, and then administrated DM1 extract (500 mg/kg, p.o.) for 4 weeks. The changes of body weight, calorie and water intakes, fasting blood glucose levels and the serum levels of glucose, insulin, triglyceride, HDL-cholesterol, AST and ALT were measured in mice. The histological changes of liver and pancreas tissues were also observed by H&E stain. C2C12 myoblasts were differentiated into myotubes and then treated with DM1 extract (0.5, 1, and 2 mg/㎖) for 24 hr. The expression of myosin heavy chain (MHC), PGC1α, Sirt1 and NRF1, and the AMPK phosphorylation were determined in the myotubes by western blot, respectively. Results : The DM1 extract administration significantly decreased the calorie and water intakes, glucose, triglyceride, AST and ALT levels and increased insulin and HDL-cholesterol in HFD-induced diabetic mice. DM1 extract inhibited lipid accumulation in liver tissue and improved glucose tolerance. In C2C12 myotubes, DM1 treatment increased the expression of MHC, PGC1α, Sirt-1, NRF-1 and the AMPK phosphorylation. Conclusion : In our results indicate that DM1 can improve diabetic symptoms by decreasing the obesity, glucose tolerance and fatty liver in HFD-induced diabetic mice, and responsible mechanism is might be related with energy enhancement.

  • This study was carried out to investigate the in vivo and in vitro inhibitory effect of a traditional herbal complex (HC) extract prepared from a mixture of four oriental herbs (Dioscorea Rhizoma, Glycine soja Sieb. et Zucc, Bombycis corpus, Fermented Glycine soja) that have been widely used for the treatment and prevention of diabetes mellitus on hyperglycemia. The water extract of HC showed potent inhibitory effect on $\alpha$-glucosidase with $IC_{50}$ value of 1.24 mg/mL. Additionally, the ethanol extract of HC was also found to exhibit significant inhibitory effect against protein tyrosine phosphatase $1{\beta}$ ($PTP1{\beta}$), which is known as a major regulator of both insulin and leptin signaling. In the $PTP1{\beta}$ inhibitory assay, the most active n-hexane fraction obtained from the ethanol extract of HC, was identified as a mixture of fatty acid derivatives by gas chromatography-mass spectrometry (GC-MS). In high-fat diet-low dose streptozotocin (STZ)-induced diabetic rat, the water extract of HC improved the oral glucose intolerance as compared with rosiglitazone. HC also caused a marked decrease of body weight and fasting blood glucose and a significant improvement on glucose tolerance in metabolic syndrome mice model. These findings support that this traditional HC may be useful in the control of blood glucose in diabetes mellitus and metabolic syndrome.

  • The aqueous Green tea comes to be used with the Oriental medicine plant, it has the numerous health benefits, including antioxidant, anti-inflammatory, and anti- carcinogenic properties. Epidermal progenitor cells give rise to multiple skin lineages: hair follicle, sebaceous gland and the overlying interfollicular epidermis. Sebocytes are the cells of the sebaceous gland, which synthesize and accumulate lipid dropolets. In order to determine the effect of Green tea on lipid production, several experiments were performed in SZ95 cells (sebocytes). We found that Green tea increased lipid droplets compared with control in a dose-dependent manner. Human sebaceous glands produce sebum, a lipid mixture of squalene, wax esters, triglycerides, cholesterol esters, and free fatty acids that is secreted onto the skin. Therefore, to investigate the effects of Green tea on intracellular lipid levels, we treated SZ95 cells with Green tea, and then examined cholesterol and triglyceride levels. After treatment of the cells with Green tea, the cholesterol and triglyceride levels of SZ95 cells were increased significantly in a dose-dependent manner.
