  • Object : This study was earned out to examine the effect of Bupleuri Radix on experimental cholestasis, and make clear a part of this mechanism. Methods : Two models of common bile duct ligation group and taurocholate load group after common bile duct ligation were induced, and Bupleuri Radix extract was taken orally for 14 days. In the 1, 2, 4, 7 and l4days after treatment, cytosolic, mitochondrial and microsomal catechol-O-methyltransferase(COMT) activities in liver were measured. Results : The activities of cytosolic, mitochondrial and microsomal COMT increased in the Blupleuri Radix treated group after common bile duct ligation and after taurocholate load and common bile duct ligation. The activities of cytosolic and mitochondrial COMT increased particularly in Blupleuri Radix treated group after taurocholate load and common bile duct ligation. Conclusions : According to the result, it is considered that Blupleuri Radix not only improves cholestatis in liver, but also decreases a genetic synthesis of taurocholic acid.

  • This study was conducted to investigate the antitoxic effects of Radix Menispermi extracts against cadmium toxicity. The experimental rats were divided into 5 groups such as control group, cadmium alone treatment group and simultaneous treatment groups of cadmium and three doses of Radix Menispermi extracts. Each group was administered with different dose of Radix Menispermi extracts such as 0.55 mg, 1.10 mg, 1.65 mg/kg wet weight in pallets for 12 weeks. Cadmium Chloride $(CdCl_2)$ was administered by 4 mg/kg body weight. The results were summarized as follows: 1. The simultaneous administration of cadmium and Radix Menispermi significantly more decreased cadmium concentration in liver tissues compared to the administration of cadmium only (P < 0.05). 2. When blood were measured, no significantly difference in haemoglobin, haematocrit, erythrocyte values compared to the administration of cadmium only. 3. The simultaneous administration of cadmium and Radix Menispermi more increased metallothionein concentration in liver than the administration of cadmium only (P < 0.05). 4. There were the histopathological slight changes in the liver and kidney tissues of rats.

  • This study was performed to investigate therapeutic effects of Achyranthis Radix extract and chitosan on the growth and differentiation of rat calvarial cells. it was found that treatment of methanol extract of Achyranthis Radix for 2 days caused 2.4-fold increase in the growth of rat calvarial cells. However, chitosan treatment caused only 1.9-fold increase in the cell growth. Treatment of methanol extract of Achyranthis Radix for 14 days caused 2-fold increase in the growth of rat calvarial cells. Alkaline phosphatase activity, one of the markers for bone cell differentiation, was increased approximately by 1.7-fold and 2.9-fold by the treatment of methanol extract of Achyranthis Radix for 2 days and 14 days, respectively. These results suggest that Achyranthis Radix extract could be beneficial for bone regeneration.

  • The purpose of this study was to investigate the effects of Astragali Radix on the diet-induced hyperlipidemia in rats. Hyperlipedemia was induced in rats with high fat diet. Rats were divided into 4 groups, normal group(supplied enough water and feeds only), high fat diet administered group(supplied high fat diet for 4 weeks, Control group) and Astragali Radix administered group(supplied high fat diet and Astragali Radix lyophilization extract for 4 weeks, 178.6 mg/kg(rat) in sample A, 297.8 mg/kg(rat) in sample B). Body weight, liver weight and serum lipid levels were evaluated. The water extract of Astragali Radix decreased body weight, liver weight, total cholesterol, LDL-cholesterol, triglyceride and phospolipid in high fat diet induced hyperlipidemia in rats, and increased HDL-cholesterol.

  • In this paper, an efficient butterfly structure for Radix-4 FFT algorithm using DA(Distributed Arithmetic) is proposed. It is shown that DA can be efficiently used in twiddle factor calculation of the Radix-4 FFT algorithm. The Verilog-HDL coding results for the proposed DA butterfly structure show $61.02\%$ cell area reduction comparison with those of the conventional multiplier butterfly structure. furthermore, the 64-point Radix-4 pipeline structure using the proposed butterfly and delay commutators is compared with other conventional structures. Implementation coding results show $46.1\%$ cell area reduction. Due to its efficient processing scheme, the proposed FFT structure can be widely used in large size of FFT like OFDM Modem.

  • Objectives : Through the literature on the effect of Aconiti Cliare Tuber, Radix Aconiti, we are finding out the clinical posibility and revealing the more effective to intractable disease. Methods : We inverstigated the literatures of Oriental Medicine and experimental reports about Aconiti Cliare Tuber, Radix Aconiti. Results : 1. The taste of Aconiti Cliare Tuber, Radix Aconiti is hot, sweet, bitter, warm and hot, and the effect is dehumidification, warm up and relieve the pain, so it can be used for arthritis, hemiplegia, carpopedal spasm, sciatica, cancer, numbness. 2. A toxic constituent of Aconiti Cliare Tuber, Radix Aconitiis is induced by aconitine alkaloid, develope toxic symptoms and result in death. So it needs suitabe treatment for safety. 3. It is known that the toxicopathy due to Radix Aconiti was 3-30g(dosage for adult) and Aconiti Ciliare Tuber was 1-9g. But only using aconitine alkaloid to oral feeding, the toxicopathy due to 0.2mg/kg and lethal dose is 3-4mg. So we using this for treating, we must be careful and need more varialble study about toxicopathy, lethal dose. 4. On clinical treatment, we thought Aconiti Cliare Tuber, Radix Aconiti is so effective to intractable disease after control the toxicity, it may be need variable study on toxicity and clinical effects.

  • Objectives: This study was performed to investigate the effects of water extract from Cynanchi Wilfordii Radix on prevention of hyperlipidemia and liver damage induced by alcohol. Methods: Except for the normal group, we fed rat on 25% alcohol for 55 days. And water extracts from Cynanchi Wilfordii Radix were administrated for the Cynanchi Wilfordii Radix group during the same period. We measured the serum components in rat's blood, body weight and weight of liver. Results: At first, we observed effects of Cynanchi Wilfordii Radix on prevention of hyperlipidemia induced by alcohol. Cynanchi Wilfordii Radix group showed significant decrease of total cholesterol and triglyceride in comparison with those of the control group. Cynanchi Wilfordii Radix group showed significant increase of HDL-cholesterol in comparison with those of the control group. Cynanchi Wilfordii Radix group showed significant increase of body weight in comparison with those of the control group in 4weeks and 8weeks. At second, we observed effects of Cynanchi Wilfordii Radix on prevention of liver damage induced by alcohol. Cynanchi Wilfordii Radix group showed significant decrease of GPT and ALP in comparison with those of the control group. Cynanchi Wilfordii Radix group showed significant increase of liver weight in comparison with those of the control group. Conclusions: Reviewing these experimental results, it appears that water extracts from Cynanchi Wilfordii Radix have pharmaceutical efficacy on prevention of hyperlipidemia and liver damage induced by alcohol. Therefore further additional study should be conducted to elucidate in depth the pharmaceutical efficacy of these.

  • Objectives : The purpose of this study was to investigate the nodakenin and decursin contents in each fermented Angelicae gigantis Radix by 4 species of ferment strains. Methods : The strains of fermented Angelicae gigantis Radix were Lactobacillus plantarum(SE1), L. acidophilus(AC), Bacillus subtilis(B2) and B. licheniformis(BL2). The fermentative changes of nodakenin and decursin were analyzed using HPLC. Results : All of 4 species strains reduced nodakenin and decursin concentration in Angelicae gigantis Radix by fermentation. But fermentability were difference between strains. The nodakenin concentration of AC was lower than B2. The decursin concentrations of SE1 and AC were lower than B2 and BL2. Conclusions : 4 species of fermental strain were difference decomposable rate with nodakenin and decursin in fermented Angelicae gigantis Radix.
