  • This study was performed to evaluate the biological activity and protective effect of Cassia tora ethanol extracts against D-galactosamine induced hepatotoxicity in rats. Male Sprague-Dawley rats were grouped into normal group, D-galactosamine treated group(control), D-galactosamine plus 0.25% Cassia tora extracts treated group and D-galactosamine plus 0.5% Cassia tora extracts treated group. Normal and control group were fed control diet and Cassia tora extracts treated groups were fed experimental diets containing 0.25% or 0.5% Cassia tora ethanol extracts for 5 weeks. Body weight gain and liver weight of rats were not significantly different between groups. Cholesterol and triglyceride concentrations in serum and liver were significantly lower in rats treated only with D-galactosamine compared to normal group, and improved in Cassia tora extracts supplemented rats. D-galactosamine treatment significantly increased serum aspartate transaminase, alanine transaminase, gamma glutamyl transferase and alkaline phosphatase, however, the activities of aspartate transaminase and alanine transaminase were significantly decreased in Cassia tora extracts supplemented rats when compared with D-galactosamine treated control group. Cassia tora extracts significantly suppressed the D-galactosamine-induced elevation of liver thiobarbituric acid reactive substances(TBARS) contents. Superoxide dismutase activity was decreased by D-galactosamine treatment, however by the supplementation of Cassia tora ethanol extracts, significantly increased in dose-dependent manner. Glutathione peroxidase activity in rats fed diets containing Cassia tora extracts was decreased compared to control. Based on these results, we concluded that Cassia tora ethanol extracts may prevents the D-galactosamine-induced hepatotoxicity probably via an antioxidant mechanism.

  • This study was conducted to investigate the physicochemical properties of the ethanol extracts and soluble dietary fiber from Cassia tora L. seed. The proximate composition of Cassia tora, soluble solid contents, color intensity and contents of emodin and rhein of Cassia tora extract, molecular mass distribution, sugar contents and viscosity of soluble fiber from Cassia tora were analyzed. Cassia tora contains 12.6% of moisture, 5.2% of ash, 13.4% of crude protein, 7.2% of crude fat, 8.8% of insoluble fiber and 48.3% of soluble fiber. The effects of extract condition on soluble solid contents, color intensity and contents of emodin and rhein of Cassia tora extract were investigated. The soluble solid contents were higher in 70% or 50% ethanol extracts than those in 100% ethanol extracts and showed highest value in grind sample extracts. In Hunter's color value, 100% ethanol extracts and whole Cassia tora sample extracts were higher in L and b value, but on the contrary, were lower in a value, than those of the other. The highest emodin and rhein contents were observed in 70% and 50% ethanol extracts, respectively, and showed higher value in room temperature extracts than in heating extracts. The molecular mass of soluble fiber from Cassia tora seed was estimated by gel filtration chromatography. Most soluble fiber(80%) exhibited a molecular mass range of between 50~2000 kDa. The major sugars of soluble fiber from Cassia tora seed were identified as xylose, mannose and galactose. The apparent viscosity of 0.5% soluble fiber from Cassia tora seed was 33 mPas showing a higher value than pectin or xanthan gum.

  • Many of plants had been reported having immunostimulating activity. This study reports the immunostimulating activity of Cassia tora L. (Leguminosae) seed, by means of solvent extraction method. Ethanol extract and solvent fractions, n-hexane, chloroform, ethylacetate, n-butanol and aqueous layer of Cassia tora L. seed were tested for immunostimulating activity in vitro. The ethylacetate-soluble fraction caused significant inhibition on the production of nitric oxide by murine macrophages (RAW 264.7), and mouse splenocytes were also stimulated at the concentration of 10 pgfmL. Three anthraquinones, chrysophanol (1), isochrysophanol (2) and aloe-emodin (3) with immunostimulating activity were isolated from the ethylacetate-soluble fraction of Cassia tora L. seed through activity-monitored fractionation and isolation method. These results permit Cassia tora L. to be useful as one the of natural immunostimulating crops.

  • 본 논문에서는 Ad Hoc 네트워크에서의 라우팅 알고리즘인 TORA 의 라우팅 유지관리 방법에서 발생하는 비효율적인 컨트롤 패킷들을 줄이는 방법을 제안한다. Adv-TORA에서는 DN(Downstream)이 소멸되는 노드에서 STP(Stop) 패킷을 주변 노드에 발송하여 끊어진 경로로 데이터 패킷이 발송되는것을 사전에 방지한다. 또, DN 소멸 노드의 주위에서 그래프의 재구성 작업이 일어났던 TORA 와는 상이하게, 단순히 지역적 라우트 경로를 초기화시킴으로서 TORA 의 컨트롤 패킷 부담을 줄인다. 또한, 통신에 참여하지 않는 노드들의 불필요한 라우트 정보 유지를 최소화하고, 라우트 요구 발생시에만 라우트 재구성 작업을 수행한다.

  • Four cropping systems, soybean mono-cropping, Cassia tora mono-cropping, soybean-C. tora companion cropping and soybean-C. tora intercropping, were compared for number of soil nematodes and soybean growth in upland field in 1986. Soybean was cultivated as an after-crop of four different cropping systems from 1987 to 1989, and observations were continued. Soil nematode was not found in C. tora mono-cropping plot from mid growing season of C. tora while many nematodes were found in soybean mono-cropping plot in 1986. A few nematodes were found for 3 years in soybean field after one season cultivation of C. tora in 1986. Number of nematodes was lower in soybean-C. tora companion and inter-cropping plots compared with soybean mono-cropping, and was also lower for 3 years in soybean field after one season companion and inter-cropping culture in 1986 compared with continuous soybean cultivation plot. No root nodule was formed on C. tora root, but number of root nodules of soybean plant grown in C. tora companion and inter-cropping plots was not different with soybean mono-cropping plot. Number of pods. number of seeds and seed weight per soybean plant grown in C. tora companion and inter-cropping plots were almost same with soybean mono-cropping plot. When soybean was cultivated in field after one season C. tora mono, companion or inter-cropping, pod and seed number, and seed weight per plant were higher than continuous soybean cultivation field.

  • This study was conducted to investigate the effect of Cassia tora ethanol extracts on carbon tetrachloride($CCl_4$)-induced hepatotoxicity in rats. Male Sprague-Dawley rats were divided into the following 4 groups: normal group, $CCl_4$, treated group, $CCl_4-0.25%$ Cassia tora ethanol extracts group and $CCl_4-0.5%$ Cassia tora ethanol extracts group. Rats were fed with each experimental diet and water for 5 weeks. Liver weights of rats treated only with $CCl_4$, were significantly increased compared to normal group, but not in rats fed diet containing Cassia tora ethanol extracts. Cholesterol and triglyceride contents in serum and liver were also not influenced by either $CCl_4$, treatment or the supplementation of Cassia tora ethanol extracts. $CCl_4$, treatment significantly increased ALP activities, however the supplementation of Cassia tora ethanol extracts significantly decreased the activities of serum ALT, AST, ${\gamma}-GTP$ in dose-dependent manner. Cassia tora ethanol extracts significantly reduced $CCl_4-induced$ elevation of liver TBARS contents. Activities of superoxide dismutase and catalase were decreased by $CCl_4$, treatment, however by the supplement of Cassia tora ethanol extracts slightly increased activities of SOD and catalase. The activity of glutathione peroxidase in groups fed diets containing Cassia tora ethanol extracts was significantly decreased compared to that of the control group. These results suggest that Cassia tora ethanol extracts may exert protective effect against $CCl_4-induced$ liver injury through the prevention of lipid peroxidation.

  • This study was undertaken to investigate the effect of Cassia tora ethanol extract on the lipid levels in serum and liver of rats fed high cholesterol diet. Experimental rats were divided into the following 4 groups: normal diet group, high cholesterol diet group, high choleslerol-0.25% C. tora ethanol extract group and high cholesterol-0.5% C. tora ethanol extract group. After 4 weeks, rats were sacrificed and analyzed the serum lipid profiles, activities of serum alanine aminotransferase (AST), aspartate aminotransferase (ALT), hepatic glucose-6-phosphate dehydrogenase (G6PDH) and malic enzyme (ME). It was also determined the contents of total cholesterol, triglyceride and thiobarbituric acid reactive substances (TBARS) in liver. There was no difference in weight gains between experimental groups. The concentrations of serum total cholesterol, free cholesterol, triglyceride and free fatty acid were tended to be decreased in C. tora groups compared with control group. HDL-cholesterol concentration was significantly decreased in high cholesterol diet group and slightly increased by C. tora ethanol extract feeding. The contents of liver cholesterol and triglyceride were higher in high cholesterol diet group than normal group, but significantly decreased by feeding of C. tora ethanol extract. Supplementation of 0.5% C. tora extract decreased significantly the activities of hepatic G6PDH and ME. Activities of serum AST, ALT and contents of liver TBARS were tended to be increased with high cholesterol diet and reduced by C. tora ethanol extract supplementation but had not significance. These results suggest that C. tora ethanol extract may exert a lipid lowering effect in serum and liver of rats.

  • This study was carried out to investigate the extraction yield, the contents of total phenol substances and antioxidative substances, electron donating abilities, nitrite scavenging abilities of water and ethanol extracts from Cassia tora L. and Pueraria thunbergiana and antioxidative activity of water and ethoanol extract from Cassia tara L. Tatal phenol substances of water and ethanol extract from Cassia tora L. and Pueraria thunbergiana showed nearly the same levels, and the antioxidative substances of water and ethanol extract from Pueraria thunbergiana has as much as two times higher than those from Cassia tara L.. The nitrite scavenging abilities were measured at pH 1.2, 3.0, 4.2 and 6.0, respectively. Water and ethanol extracts from Cassia tora L showed 14.9%∼22.3% and 49.1%∼56.7%, and those from Pueraria thunbergiana revealed 57.7%∼61.0% of nitrite scavenging abilities, respectively. Especially the extracts from Pueraria thunbergiana showed higher pH dependence than those from Cassia tora L. The electrol donating abilities of water extract from Cassia tora L. were higher than those from Pueraria thunbergiana, and vice versa in the case of ethanol extracts. In the antioxidative activitiy of extracts from Cassia tora L. against linoleic acid during storage of 20 days at 50$^{circ}C$, peroxide values at the addition level of 5mg and 10mg were consoderably lower than 2mg although peroxide value increased above 375 after 12days of storage compared with the control(BHA-added) of 129 at 8days.

  • 무선 센서 네트워크의 효율적인 에너지 사용은 무선 센서 네트워크의 수명과 관련된 중요한 요소이다. 무선센서 네트워크의 역동적인 환경에서는 전력량, 간섭 요소를 고려한 신호의 세기, 노드간의 거리 등의 특성을 고려하여 최적의 경로를 선택하는 것은 에너지 사용량에 많은 영향을 준다. TORA(Temporally-Ordered Routing Algorithm)는 이동성이 심한 무선 네트워크 환경에 적합하게 설계되어 있고 다중경로를 이용하여 링크 단절 시 빠른 복구가 가능한 장점이 있지만, 네트워크 생존의 측면에서 전력 사용의 효율성을 개선 및 보완할 필요가 있다. 본 논문에서는 TORA의 다중 경로 중에서 최적의 경로를 선택하는 방법에 대해서 논하고자 한다.
