The aim of the experiments was to investigate the effect of Semen Cuscutae aqua-acupuncture at the meridian point BL 20(脾兪) and BL 23(賢兪) on the blood pressure, plasma renin activity, plasma levels of aldosterone and atrial natriuretic peptide (ANP) in spontaneously hypertensive rats (SHR). The results of this study were as follows: 1. Systolic blood pressure was decreased significantly after Semen Cuscutae aqua-acupuncture at the meridian point BL 20, BL 23. 2. Plasma renin activity was increased significantly after Semen Cuscutae aqua-acupuncture at meridian point BL 23, BL 20. 3. Plasma levels of aldosterone was increased significantly after Semen Cuscutae aqua-acupuncture at the meridian point BL 20. 4. Plasma levels of atrial natriuretic peptide (ANP) was increased significantly after Semen Cuscutae aqua-acupuncture at the meridian point BL 23, but it was decreased significantly after Semen Cuscutae aqua-acupuncture at the meridian point BL 20. These results suggest that the changes of the depressor response after Semen Cuscutae aqua-acupuncture at the meridian point BL 20, BL 23 are related to the changes of the plasma renin activity, plasma levels of atrial natriuretic peptide (ANP) and aldosterone.

BL(Blended Learning) has been presented as a promising alternative learning approach. BL is defined as a learning approach that combines e-learning and face-to-face classroom learning. The adoption of BL in computer practice class is necessary due to the characteristics of computer practice class itself. This study proposes a research model that examines the determinants of learner's satisfaction of computer practice classes in BL environment. Considering the characteristics of computer practices classes contents and instructor interaction were identified as the determinants. The research model is tested using a questionnaire survey of 141 participants. Confirmatory factor analysis (CFA) was performed to test the reliability and validity of the measurements. The partial least squares (PLS) method was used to validate the measurement and hypotheses. The empirical findings shows that contents easiness and contents constructs are the primary determinants of instructor interaction in BL. Instructor interaction was also found to be related to the learner's satisfaction resulting in re-using. The findings provide insight into the planning and utilizing BL in computer practice classes to enhance learner's satisfaction.

Postharvest decay of onion bulbs was examined by inspecting the commercial packages in the market or in storage. Bulb rot incidence was unexpectedly high, and onion bulbs with 1st quality grade were rotten most severely by 51%, followed by 32% for 2nd and 21% for 3rd grades. This indicates that larger bulbs had higher incidences of bulb rots. Major pathogens associated with basal and neck rots were Fusarium oxysporum and Aspergillus sp. or Botrytis allii, respectively, of which basal rot was most prevalent and damaging during storage. Among the epiphytic microorgani는 from onion plants, several Bacillus and Paenibacillus spp. and previously selected Pseudomonas putida and Trichoderma harzianum had inhibitory efficacy against bulb rot pathogens. Among these B. amyloliquefaciens BL-3, Paenibacillus polymyxa BL-4, and P. putida Cha 94 were highly inhibitory to conidial germination of F. oxysporum and B. allii. P. putida Cha 94, B. amyloliquefaciens BL-3, P. polymyxa BL-4, and T. harzianum TM were applied in the rhizoplane of onion at transplanting. Initially antagonist populations decreased rapidly during the first one month. However, among these antagonists, rhizoplane population densities of BL-3, Cha 94, and TM were consistently high thereafter, maintaining about 10$^4$-10$^{5}$ cells or spores per gram of onion root up to harvest time. The other bacterial antagonist BL-4 survived only for two months. TM was the most effective biocontrol agent against basal rot, with the number of rotten bulbs recorded at 4%, while that of the control was 16%. Cha 94 was effective for the first 20 days, but basal rot increased thereafter and had about the same control efficacy as that of BL-3 and BL-4. When the antagonists were applied to the topping areas of onion bulbs at harvest, TM was the most effective in protecting the stored onion bulbs from neck rotting. The second effective antagonist was BL-3. TM and BL-3 completely suppressed the neck rot in another test, suggesting that biocontrol of postharvest decay of onion using these microorganisms either at the time of transplanting or at harvesting may be promising.

Objectives : The purpose of this study is to investigate the anti-oxidative effect of electroacupuncture at Shinmaek($BL_{62}$) in rats. Methods : In order to cause oxidative stress, AAPH was administered to the abdominal cavity of rats, after we stimulated $BL_{62}$ of the rat by electroacupuncture. Blood test and anti-oxidative test(LDL-cholesterol, GOT, GPT SOD, GSH, catalase, NO, MDA) were performed at the end of treatment. Results: 1. SOD, glutathione, catalase activity were significantly increased in the $BL_{62}-EA$ group compared with the holder group. 2. NO density was significantly decreased in the $BL_{62}-EA$ group compared with the holder group. 3. Glutathione was significantly increased in the $BL_{62}-EA$ group compared with the sham-EA group. Conclusion : These results suggest that electroacupuncture at $BL_{62}$ has an anti-oxidant effect in human.

In this study, we have investigated the effect of Biphenyl Dimethyl Dicarboxylate (DDB), a synthetic analogue of Schizandrin C isolated from Schizandrae Fructus on cytochrome $P_450$ lAl and 2Bl, and the protective mechanism against $CCl_4-induced$ hepatotoxicity in rat liver. After DDB was administered into male rats for different periods of time (1~7 days) and with different doses (25, 50, 100 and 200 mg/kg), mRNA levels of CYPlAl were measured by polymearse chain reaction (PCR) and assayed the activities of CYPlAl specific ethoxyresorufin-O-dealkylase (EROD) and CYP2Bl specific benzyloxyresorufin-O-dealkylase (BROD). DDB treatment resulted in increase in CYP2Bl mRNA level and BROD activity, whereas there was no change in CYPlAl mRNA level and EROD activity. This effect of DDB was time-and dose-dependent and reached maximal level by 3 day and 200 mg/kg treatment. In addition, rats were pre-treated with DDB at doses of 25, 50 or 100 mg/kg daily for 4 days, 3-hr after final treatment on the 4th day, $CCl_4$ 0.3ml/kg was intraperitonially injected into the rats to examine the effect of DDB on $CCl_4-induced$ hepatic injury. Serum levels of ALT and AST were determined and histopathological examination was done in rat liver. Furthermore, we have measured hepatic microsomal malondialdehyde(MDA) level, a parameter of lipid peroxidation. Based on serum ALT level and lipid peroxidation, pretreatment of DDB, 50 mg/kg appeared the most protective effect against $CCl_4-induced$ heapatotoxity. These results indicate that DDB stimulates CYP2Bl mRNA level and BROD activity in time and dose dependent manner and suggest that protective effect of DDB on $CCl_4-induced$ hepatotoxicity may be mediated through free radical scavenging.

본 연구는 probiotics와 prebiotics로 구성된 synbiotics 섭취가 건강한 성인의 배변 활동 및 변내 균총의 개선 효과를 확인하고자 하였고, probiotics 섭취 중단 후에도 prebiotics인 XOS 섭취가 장내 유익균총의 유지에 미치는 영향을 파악함으로써 XOS의 건강기능성 확인을 위한 근거자료를 확보하고자 하였다. 본 연구결과 BL2XO6군과 BL2XO2군의 체위 자료는 두 군 간에 유의적인 차이를 보이지 않았다. 변내 pH는 시료 섭취 전 두 군 모두 7.0이하로 약 산성이었으나, 시료 섭취 1주차 BL2XO6군에서 pH 7.16으로 유의적으로 높았으나 2주차 이후는 pH 7.0 이하의 값을 보여 시료 섭취에 따른 차이는 나타나지 않았다. 변내 균총의 변화를 보면 BL2XO6군의 경우 Clostridium spp. 은 시료 섭취 후 변 내 균 수가 감소하는 양상을 보인 반면, Bifidobacterium spp.은 시료 섭취 후 서서히 증가하는 양상을 보여 4주차에 시료 섭취 전에 비해 유의적으로 높았으나, 이외 주차에서는 유의적인 차이를 보이지 않았다. B. longum은 모든 주차에서 통계적으로 유의하지 않았으나 서서히 증가하는 추이를 보였다. BL2XO2군의 경우 시료 섭취 후 Lactobacillus spp.과 B. longum은 synbiotics 섭취 1주에만 증가하는 추이를 보였다. 각 주차별로 변 내 균총의 변화율에서 군별로 유의적인 차이를 보인 균총은 Clostridium spp.와 Lactobacillus spp.이었다. 즉, Clostridium spp.은 2주차에서, Lactobacillus spp.는 4주차에서 BL2XO6군과 BL2XO2군 사이에서 유의적인 차이를 보였다. 시료 섭취 전·후 Bacteroidetes와 Firmicutes의 비율은 두 군 모두 변화가 없는 것으로 나타났다. 또한, 시료 섭취 전·후의 변의 양, 변의 상태 및 배변 횟수, 복통 및 CSS점수에 유의적인 차이를 보이지 않았을 뿐만 아니라 군에 따른 차이 역시 존재하지 않았다. 이상의 결과 synbiotics 섭취 후 prebiotics만을 섭취할지라도 장내 균총의 변화에 긍정적인 영향을 미치는 것으로 나타나고 있을 뿐만이 아니라 정상적인 배변 활동을 유지하고 있어 synbiotics 섭취 후 prebiotics로 XOS 섭취는 자일로올리고당을 선택적으로 이용할 수 있는 B. longum을 장내에서 지속적으로 증식할 수 있도록 도와 장내 균총을 개선하는 효과와 정상적인 배변활동을 통한 장 건강에 도움을 줄 수 있을 것으로 사료된다.
