  • The effect of captafol on the hematological value, erythrocyte membrane and plasma biochemical value was investigated using blood of SPF Sprague-Dawley male rats in vitro. For the anticoagulations, we used 0.5mg of heparin per $10m{\ell}$ of blood from vena cava. Three con-centrations($0.1{\times}10^{-4}M$, $1{\times}10^{-3}M$ and $1{\times}10^{-2}M$) captafol in ethanol were added to the each $2.5m{\ell}$ blood so that the linal concentration of ethanol was 1%. The blood contained with each concentration of captafol was incubated at $37^{\circ}C$ C for 2 hours under 5% $CO_2$ gas The whole blood and plasma were examined for hematological vaJues, erythrocyte membrane damage and biochemical values, respectively. The results obtained were summarized as follows ; 1. The number of RBC in $1{\times}10^{-2}M$ group and the concentration of MCHC in $1{\times}10^{-3}M$ group were significantly (p<0.05) decreased and increased from that of control values, respectively. The percentage of Hct was significantly (p<0.05) decreased with dose-response. 2. Erythrocyte fragility rate of $1{\times}10^{-3}M$ and $1{\times}10^{-2}M$ group were significantly (p<0.01) increased from that control with dose response. 3. Potassium ion level of $1{\times}10^{-2}M$ was significantly (p<0.05) increased from that of control. 4. The concentration of total bilirubin in the $1{\times}10^{-3}M$ and $1{\times}10^{-2}M$ groups were significantly increased from that of control. The enzyme level of creatine kinase in $1{\times}10^{-2}M$ group was significanlty (p<0.05) decreased from control value.

  • Onion (Allium cepa L.) is one of the richest sources of flavonoids in human diet. Onion peel contains over 20 times more quercetin than onion flesh. In this study, we studied the effects of onion peel water extract (OPE) on the blood lipid profiles in mice. The onion peel extracts was extracted with hot water. The experimental groups were divided with 3 groups (n = 6) of ICR male mice: normal diet + distilled water (NC), high-fat diet + distilled water (HF), high-fat diet + onion peel water extract 20 mg/kg (OPE-20). The oral administration was conducted daily. The experimental period was 7 weeks. Onion peel water extract showed higher concentration of polyphenol gallic acid and anti-oxidant trolox equivalent than the ethanol extract. The body weight gain and food efficiency ratio was significantly lower in the OPE-20 group as compared with HF group (p < 0.05). The epididymal fat and retroperitoneal fat showed significantly lower weights and sizes in the OPE-20 group as compared with HF group (p < 0.05). The serum levels of total cholesterol, LDL cholesterol and triglyceride were significantly lower in the OPE-20 group as compared with HF group (p < 0.05). The OPE-20 group showed higher HDL cholesterol concentration than HF group (p < 0.05). Atherogenic index was ignificantly lower in as compared with HF group (p < 0.05). The serum levels of glucose, GOT and GPT were significantly lower in the OPE-20 group as compared with HF group (p < 0.05). In these results, we suggests that onion peel water extracts supplementation can reduces the serum lipid components and improves the lipid metabolism in hyperlipidemic mice induced with a high-fat diet.

  • Near infrared spectrophotometry(NIR) was developed as a non-invasive determination of blood alcohol. The first pure alcohol/water samples were prepared with ethanol concentration from 0.01 to 0.1%(w/w). Analysis of the second-derivative data was accomplished with multilinear regression(MLR). The standard error of calibration(SEC) of ethanol in ethanol/water solutions was approximately 0.0039%. The calibration models were established from the blood alcohol spectra by MLR and PLSR analysis. The best calibration was built with the second-derivative spectra of 2266 and 2326 nm by MLR. Second-derivative spectra in the spectral ranges of 1100~1340, 1500~1796 and 2064~2300 nm with four PLSR factors provided the standard error of prediction(SEP) of 0.030%(w/w). These results indicate that NIR may be applied for a fast non-invasive determination of alcohol in the blood.

  • insenosides from Panax ginseng are well known for their diverse pharmacological effects including antithrombotic activity. Since adventitious roots of mountain ginseng (ARMG) also contain various ginsenosides, blood flow-improving effects of the dried powder and extract of ARMG were investigated. Rats were orally administered with dried powder (PARMG) or ethanol extract (EARMG) of ARMG (125, 250 or 500 mg/kg) or aspirin (30 mg/kg, a reference control) for 3 weeks. Forty min after the final administration, carotid arterial thrombosis was induced by applying a 70% $FeCl_3$-soaked filter paper outside the arterial wall for 5 min, and the blood flow was monitored with a laser Doppler probe. Both PARMG and EARMG delayed the $FeCl_3$-induced arterial occlusion in a dose-dependent manner, doubling the occlusion time at high doses. In mechanism studies, a high concentration of EARMG inhibited platelet aggregation induced by collagen in vitro. In addition, EARMG improved the blood lipid profiles, decreasing triglyceride and cholesterol levels. Although additional action mechanisms remain to be clarified, it is suggested that ARMG containing high amount of ginsenosides such as $Rg_3$ improves blood flow not only by inhibiting oxidative thrombosis, but also by modifying blood lipid profiles.

  • 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.

  • Hepatoprotective effects of corn gluten hydrolysates (CGH) were investigated in rats orally treated with ethanol (30%(v/v), 3 g/kg body weight/day) for 4 weeks. Six-week old Sprague-Dawley male rats were divided into four dietary groups: normal diet (N), alcohol diet (E), E+CGH 1% diet (CGH-1%), and E+CGH 3% diet (CGH-3%). Body weights and liver indices were not significantly different among the four groups. However, food intakes were lower in the CGH groups than in the normal group (p<0.05). The administration of CGH significantly reduced serum alkaline phosphatase activity by 30% compared to the alcohol diet group. Among the antioxidative enzymes assessed, catalase activity was significantly decreased by 79% in the CGH diet groups compared to the alcohol diet group. In comparison to the alcohol-treated group, aldehyde dehydrogenase activity was increased by 20%, while microsomal ethanol oxidizing system activity was decreased by 20% in the CGH-treated groups. Furthermore, the area under the curve of the blood acetaldehyde concentration versus time profile after the administration of ethanol was significantly lower for the CGH rats than for the ethanol or asparaginic acid treated groups. Thus, CGH seems to offer beneficial effects by protecting against ethanol-induced hepatotoxicity by improving the acetaldehyde-related metabolizing system.

  • To investigate anti-thrombosis and anti-oxidation activities of the root of Arctium lappa L (RALL), which has been used as foodstuff and oriental medicine in Korea, the ethanol extract and its subsequent organic solvent fractions of the RALL were prepared. The yield of ethanol extraction was 10.94%, and the content of total polyphenol and total sugar of ethanol extract were 5.01 and 694.53 mg/g, respectively. The fraction yields of n-hexane, ethylacetate (EA), butanol and water residue were 1.62, 0.42, 5.98 and 85.38%, respectively. In anticoagulation activity assay, the ethanol extract of RALL did not show significant changes in thrombin time (TT), prothrombin time (PT) and activated partial thromboplastin time (aPTT), whereas the EA fractions showed 13 folds extended TT, PT, and aPTT respectively. Interestingly, the water residue showed strong activation effect against blood clotting factors with shortened aPTT, which might provide the evidence of coagulation agent of RALL in folk remedy. In anti-platelet aggregation assay, the activity of the ethanol extract and its fractions were comparable to that of aspirin. Especially the EA fraction showed 2-folds higher inhibitory activity than aspirin. In anti-oxidation activity assay, the EA fraction also showed strong in DPPH, ABTS and nitrite scavenging activity, and reducing power activity. The extract and fractions of RALL have ignorable hemolytic activity against human RBC up to 0.5 mg/mL concentration. Our results suggest that the EA fraction of RALL have potentials as safe and novel anti-thrombosis agent.

  • After pretreatment with ginseng followed by induction of acute intoxication of alcohol, the activities of alcohol dehydrogenase (ADH), microsomal ethanol-oxidizing system (MEOS) and aldehyde dehydrogenase(Ald DH) increased respectively compared to the groups treated with alcohol alone. In case that ginseng was given to rats fed with 5% alcohol instead of water for 60 days, the activities of ADH and MEOS increased compared to the groups treated. On the contrary, the activity of Ald DH in mitochondrial fraction decreased to an extent of about 35% in chronic alcoholism, but after pretreatment of ginseng the activity was restored to the control level. On the other hand, the catalase activity was not significantly affected by either treatment. Ginseng butanol fraction significantly increased the serum isocitrate dehydrogenase activity which is inhibited by alcohol-treated in rat. Alcohol-induced lactate dehydrogenase activity was decreased to control level in liver by ginseng treatment. And the serum level of lactic acid also decreased by ginseng treatment in alcohol-intoxicated rat. Ginseng butanol fraction markedly decreased the xanthine oxidase activity in the ethanol-treated rat liver. It was also observed that ginseng reduced the blood concentration of uric acid on experimentally reduced hyperuricemia by alcohol treatment. Uricase activity was not affected by either treatment. Ginseng butanol fraction decreased the hepatic aniline hydroxylase activity which was induced by alcohol-treated rat. These results suggest that the treatment with ginseng can be promoted the recovery from alcohol intoxication and some therapeutic effect on alcoholinduced metabolic disease.

  • The present study was performed to evaluate the effect of medicinal plant extract on relieving hangovers in mice administered alcohol. The animals were divided into three groups. Each group was treated with fermented plant extract, non-fermented plant extract, or water 30 min after consuming ethanol (2 mL/kg). A locomotor activity test showed that all groups had decreased motor activity until 40 min after plant extract administration. The mice treated with water had lower motor activity until 100 min post-administration. However, the group treated with non-fermented plant extract showed increased motor activity 40 min post-administration, and the higher activity level was maintained until 120 min post-administration. The animals treated with fermented plant extract had a level of motor activity between those of the groups treated with water or non-fermented plant extract. Blood was collected from each mouse 120 min post-administration and aldehyde concentration was measured. The group treated with non-fermented plant extract had a significantly higher (p < 0.05) aldehyde concentration than the other groups. These results demonstrate that the non-fermented medicinal plant extract helped alleviate hangovers 40 min after administration by reducing aldehyde concentrations in the blood.
