Objectives: Sauchinone is a lignan isolated from Saururus chinensis which is a traditional herb in Korea. Tacrine, the cholinesterase inhibitor, had been used as a drug for treating Alzheimer disease. However, therapeutic application of tacrine is restricted because of hepatotoxicity. This study investigated whether sauchinone can protect hepatocytes against the mitochondrial dysfunction and apoptosis caused by tacrine. Methods: We used HepG2 cells, the human-derived hepatocyte cell line, to determine sauchinone prevents tacrine-induced hepatic toxicity. After HepG2 cells were treated with sauchinone for 12 h, the cells were subsequently exposed to tacrine. Effects of sauchinone against tacrine-induced cell damage were examined by fluorescence activated cell sorter and immunoblot analysis and so on. Results: Pre-treatment of sauchinone inhibited cell death caused by tacrine in a dose dependent manner, maintaining the transition of mitochondria membrane potential. In addition, sauchinone prevented oxidative stress induced by tacrine. Conclusion: Sauchinone protects hepatocytes and mitochondria exposed to toxicity of tacrine. These results suggest that sauchinone may be a new therapeutic candidate for supplementing tacrine.

렌틸콩을 이용한 청국장의 제조의 가능성을 검토하기 위하여 대두, 렌틸콩, 그리고 대두와 랜틸콩을 혼합하여 천국장을 제조하여 품질특성을 비교 하였다. 청국장의 총 균수는 발효초기 5.22 log CFU/mL 이었으며, 발효 24시간이 경과함에 따라 모든 처리구에서 8 log CFU/mL 범위를 나타내어 렌틸콩 첨가량에 따른 뚜렷한 차이는 나타나지 않았다. 또한 pH는 발효기 진행됨에 따라 높아졌으며, 발효 72시간에는 대조구에 매해 렌틸콩을 첨가한 청국장의 pH가 낮았다. 청국장의 아미노태 질소는 발효초기에 비해 발효가 진행됨에 따라 대조구보다 렌틸콩을 첨가한 청국장이 높았으며, 발효 종료 후 청국장의 점질물의 양은 렌틸콩 단독처리구(LC)가 1134 ug/mL로 가장 높았다. 발효 72시간째 LC, SLC의 DPPH 라디칼 소거능은 각각 25.17, 35.14%로 나타내어 대조구(21.91%)에 비해 높았다. 발효 종료 후 대조구의 총 폴리페놀의 함량은 62.87 ㎍/mL이며, LC는 69.89 ㎍/mL, SLC 71.26 ㎍/m로 나타내dj, 대두 50%와 렌틸콩 50% 혼합처리구 기정 높았다. 렌틸콩 청국장의 관능검사 결과, 색과 종합적 기호도는 대두 단독치리(SC)가 향과 맛은 대두와 렌틸콩 혼합 처리구(SLC)가 가장 높았다. 대두와 렌틸콩을 혼합하여 청국장을 제조할 경우 미생물의 성장, 항산화 활성, 점질물 생성량 등이 증기되어 생리활성이 보다 우수한 청국장 제조가 가능할 것으로 사료된다. The effect of lentil bean on fermentation and quality characteristics of cheonggukjang were investigated. Cheonggukjang was prepared with different mixing ratio of cooked lentil and cooked soybean, such as cooked soy bean (S), 50% cooked lentil bean and 50% cooked soy bean (SL) and 100% cooked lentil bean (L), respectively. The pH values of cheonggukjang with soy bean and lentil bean (SLC) and cheonggukjang with Intil (LC) did not show a significant difference compared with the cheonggukjang with soybean (SC, Control) during fermentation for 72h. The viable cell count of cheonggukjang reached 9.16 (CC), 8.57 (SLC) and 8.65 (LC) log CFU/mL after fermentation for 72h at 37℃, respectively. The amino nitrogen and viscous substance contents of SLC and LC were higher than those of the control. The total polyphenol contents and DPPH radical scavenging abilities of the tested cheonggukjang were increased by fermentation. The sensory quality of SLC and LC were higher than that of the control in taste, color.

The purpose of this study was to investigate whether different hip abduction angles might alternate hip extensor muscle activity in reverse hyperextension (RHE) exercise. Fourteen healthy male subjects performed RHE in 4 hip abduction angles (-10°, 0°, 15°, and 30°). Muscle activities of longissimus, gluteus maximus, gluteus medius, biceps femoris, semitendinosus, and adductor magnus were measured by surface electromyography device. One-way repeated ANOVA was used to analyze the results from each angle of muscle and the ratio of muscle activation. During the concentric phase of RHE, gluteus medius activation was greater at 15° and 30° of hip abduction angles (p<.001) than at -10 and 0°, while biceps femoris was greatest at -10° (p<.001) followed by 0°, 15°, and 30° of hip abduction angles. During the eccentric phase of RHE, gluteus medius activation was greater at 15° and 30° of hip abduction angles (p<.003) than -10°, while biceps femoris was greatest at -10° (p<.001) followed by 15° and 30°. Our findings suggest that RHE of hip abduction at 15° and 30° might be the most appropriate angle for maximizing gluteal muscle activation.

Background and objective: Methamphetamine (Meth) is a widely abused psychostimulant that produces hyperlocomotion in rodents. Radix of Glycyrrhizae uralensis comprises a variety of bioactive components that have neuroprotective effects. In a previous study, we have demonstrated methanol extracts from radix of Glycyrrhizae uralensis (MEGR) suppress acute cocaine-induced extracellular dopamine release in the nucleus accumbens. In the present study, we investigated the effect of MEGR on acute Meth-induced hyperlocomotion. Methods: Male Sprague-Dawley rats were orally administered with MEGR (60 mg/kg and 180 mg/kg) 60 min prior to an intraperitoneal injection of Meth (1.0 mg/kg). Results: Behavioral analysis showed acute Meth greatly increased locomotor activities, while pretreatment with MEGR dose dependently inhibited the hyperlocomotion. In parallel, there were markedly increased levels of dopamine and its metabolite 3, 4-dihydroxyphenylacetic acid in the nucleus accumbens tissues in Meth-treated rats, which were also almost completely reversed by 180 mg/kg MEGR. Conclusions: These results showed that radix of Glycyrrhizae uralensis attenuates Meth-induced hyperlocomotion by inhibiting dopamine synthesis and utilization, suggesting that radix of Glycyrrhizae uralensis might be effective in blocking the rewarding effect of Meth.
