This study was devised to observe the inhibitory effects of 3 kinds of petroleum ether extracts (percolation by petroleum ether) from Korean red ginseng, Chinese red ginseng and American white ginseng on a lipolytic action of Toxohormone-L which has been known as lipolytic and anorexigenic factors. Toxohormone-L was obtained by partial purification of the ascites fluid from mice which had been Inoculated with sarcoma-180. The yields of petroleum ether extract from Korean red ginseng, Chinese red ginseng and American white ginseng were 0.64, 0.47 and 0.58 and respectively, indicating that the yield of Korean red ginseng was the highest. In vitro, at the concentration of 2 mg /ml, the inhibition rate of lipolysis by the petroleum ether extract of Korean red ginseng, Chinese red ginseng and American white ginseng were 55.1, 50.0 and 44.9% respectively, and the total inhibitory activity per gram of ginseng material were 18, 12 and 13 unit respectively, indicating that the Korean red ginseng was the most effective in the inhibition of the lipolysis.

This study was devised to observe the inhibitory effects of ethanol treatment precipitate (crude acidic polysaccharide) from Korean red ginseng on a lipolytic action of Toxohormone-L which has been known as lipolytic and anorexigenic factors. Toxohormone-L was obtained by partial purification of the ascites fluid from mice which had been inoculated with sarcoma-180. The yields of crude acidic polysaccharide from Korean red ginseng was 63.5%. In vitro, at the concentration of 500rg /ml, the inhibition rate of lipolysis by the crude acidic polysaccharide of Korean red ginseng was 38.8% and the total inhibitory activity per gram of ginseng material was 4,928 nit. In vivo, the red ginseng polysaccharide(40mg/ml in saline soon.) 16ul/g of body weight was injected to the sarcoma-180 bearing mice once In 3 days until death. The effects against the extension of life span was little but body weight gain of sarcoma-180 bearing mice decreased significantly by administration of Korean red ginseng polysaccharide compared to those of the control group.

Background: Red ginseng marc, the residue of red ginseng left after water extraction, is rich in dietary fiber. Dietary fiber derived from fruits or vegetables can promote the proliferation of probiotics, and it is a key technology in the food industry to increase the productivity of probiotics by adding growth-enhancing substances such as dietary fiber. In this study, the effect of red ginseng dietary fiber (RGDF) on the growth of probiotic bacterial strains was investigated at the phenotypic and genetic levels. Methods: We performed transcriptome profiling of Lactiplantibacillus plantarum IDCC3501 in two phases of culture (logarithmic (L)-phase and stationary (S)-phase) in two culture conditions (with or without RGDF) using RNA-seq. Differentially expressed genes (DEGs) were identified and classified according to Gene Ontology terms. Results: The growth of L.plantarum IDCC3501 was enhanced in medium supplemented with RGDF up to 2%. As a result of DEG analysis, 29 genes were upregulated and 30 were downregulated in the RGDF-treated group in the L-phase. In the S-phase, 57 genes were upregulated and 126 were downregulated in the RGDF-treated group. Among the upregulated genes, 5 were upregulated only in the L-phase, 10 were upregulated only in the S-phase, and 3 were upregulated in both the L- and S-phases. Conclusions: Transcriptome analysis could be a valuable tool for elucidating the molecular mechanisms by which RGDF promotes the proliferation of L.plantarum IDCC3501. This growth-promoting effect of RGDF is important, since RGDF could be used as a prebiotic source without additional chemical or enzymatic processing.

Purpose: The study sought to provide basic information for North Korean defectors (Sae-Tu-Min) by studying the quality of life(QoL) based on their general characteristics and health problems. Methods: The targeted subjects were 1400 North Korean settlers who were receiving settlement service by Korean National Red Cross after finishing their training at Hanawon in 2005. The data was collected from August to October in 2007. The QoL was assessed by Medical Outcomes Study Short Form-36. Collected data were analyzed by ANOVA and t-test with SPSS win 15.0 program. Result: The majority of the 466 subjects were female(77.9%). The average age was 36.8 years, 52.8% lived alone, and 64.0% were unemployed. The average QoL score of the group was $62.4{\pm}18.4$, which was markedly lower in terms of social, physical and mental health compared to the scores of immigrants to South Korea from other countries. The score was the highest for physical ability and the lowest for general health. Influential socio-demographic factors to QoL were gender, age, education, religion, annual salary, occupation, and life insurance. Employed in the subject group showed higher level of QoL on eight categories than unemployed. Concerning health problems that detracted from QoL, 18.5% of the subjects were aware they suffered from anemia and 8.8% of them recognized they suffered from attention deficits. Conclusion: The health conditions of the North Korean settlers had improved since they settled in South Korea, but their QoL was lower than other immigrants. Various programs to maintain and promote the health of North Korean settlers would be useful.

IgG와 알부민이 고스트 적혈구의 분산하에서 적 혈구의 세포막에 흡착되었다. 용액중 IgG의 농도가 0 O.1mg/mL일 때, 고스트 적혈구의 부피비가 5% 에 서 45%로 증가함에 따라 흡착으로 인한 용액중의 IgG의 농도감소는 14%에서 45%로 증가하였고, h hardened 고스트 척혈구 분산시가 고스트 적혈구 분산시보다 더 많은 단백질이 흡착되었다. 용액중 알부민의 농도가 0.075mg/mL일 때, 고스트 적헐구 의 부피가 5%에셔 70%로 증가함에 따라 용액중의 얄부민의 농도감소는 12% 에서 47%로 증가하였다. 흡착시간에 대한 IgG의 농도변화를 측정한 결과 단 백질의 흡착은 빠른 속도로 일어남을 알 수 있었고, 적혈구당 흡착된 단백질 분자수를 계산한 결과 용액 내 적혈구의 수가 증가할수록 적혈구당 흡착된 분자 수는 감소하였다.

Relationship between the causative organi는 of red-tide and environmental factors had been ecologically dealt wtih. The surveys were conducted at seven station in Jinhae Bay from July to September 1981. The water temperature and salinity had wide range, i.e. 23.3~29.3$^{\circ}C$ and 19G.78~31.29$\textperthousand$, but several chemical factors remarkably fluctuated; dissolved oxygen 102.9~210.4%, COD 2.10~8.96mg$O_2$/l, pH 8.1~9.4, $NO_3$-N trace~1, 052$\mu$g/l, $PO_4$-P 0.6~58.9$\mu$g/l and chlorophyll-a 2.18~290.5mg/$m^3$ in the observed area. The red-tide was mainly caused by two dinoflagellata taxa throughout major outbreaks occurred in July through September. Leading species of red-tide were Gymnodinium nagasakiense belong to the ajor species. During the surveyed period, cell nubers of the causative organisms of the red-tide extensively varied from 3${\times} /10^4$ cells/l to $1.5\times10^7 $cells/l with moths and stations; Prorocentrum spp. 0.3~12.5$\times\10^5$ cells/l in July; Gymnodinium nagasakiense 0.2~5.9$\times10^6 cells/l, 1.1~4.7$\times10^6$ cells/l, and 0.2~15.1$\times10^6$ cells/l in July, August, and September, respectively. Gymnodinium nagasakiense red-tide seemed to be caused by the high water temperature in summer, unusually low salinity due to heavy rains, and the concentrated nutrients for phytoplankton supplied with the municipal sewages from the urban areas and the wastewaters from the industrial complexes.

홍국의 발효에 의해서 생산된 Ang-Khak을 여러 농도의 추출물(RS1: red rice powder 0.1 g/10 mL, RS2: 0.2 g/10 mL, RS3: 0.3 g/10 mL, RS4: 0.4 g/10 mL, RS5: 0.5 g/10 mL, CS: control soybean curd)로 만들어 기능성 홍두부(RS)를 제조하였다. 홍두부의 저장 중 변화에서 pH와 산도 그리고 일반 세균수에서 모두 RS5에서 가장 변화가 적었고, 색도에서는 전체적으로 황색도가 약간 증가하였으며, texture의 경우는 경도와 검성 그리고 탄성이 증가 후 감소하는 경향을 보였다. 이는 두부를 1$0^{\circ}C$에 저장하면서 초기에 수분이 빠져나가 두부의 경도가 증가된 후 부패가 진행되면서 다시 낮아진데 기인된다. 1주간 저장 후에 CS보다는 RS에서 물성의 보존이 더 잘 이루어짐을 알 수 있었으며, 홍국의 기능성을 활용하여 두부의 저장수명을 연장시키기 위한 더 많은 노력이 필요한 것으로 사료된다.

홍삼 추출물이 유산간균 3종(L. acidophilus, L. casei 및 L. salivarius ssp. salivarius)과 병원성 균으로서 E. coli 및 L. monocytogenes에 대한 성장 촉진과 억제 효과를 홍삼 추출물 0, 1, 2, 5와 $10\%$ 농도로 조사하였으며, 홍삼 추출물에 의한 pH 저하를 buffer제를 사용하여 조정하고 미생물의 성장을 대조구와 비교하여 조사하였다. 유산간균 3종의 경우 홍삼 추출물 $1\%$ 농도까지는 무처리구와 유사한 성장을 보였으나, $2\%$이상의 홍삼 추출물 첨가 시 농도가 높아질수록 유산균의 성장도 둔화되었다. E. coli의 경우 홍삼 추출물이 $1\%$부터 높아질수록 성장이 억제되었고, L. monocytogenes의 경우 $5\%$ 이상의 처리구에서 억제 효과가 있었다. Buffer제를 사용하여 pH를 조정하고 홍삼 추출물을 $10\%$ 첨가한 구와 pH를 조정하지 않은 구를 비교하여 보면 유산간균과 병원성 균의 성장이 두 구간에 모두 억제되므로 미생물의 억제 효과가 홍삼 추출물 중의 유기산에 의한 pH 저하가 원인이 아님을 알 수 있었으며, 이와 같은 미생물의 성장억제 효과는 홍삼 추출물 중 다른 유효성분에 의한 것으로 생각되어진다.

고추가루의 소비자 선호도를 평가하기 위한 객관적 방법을 확립하기 위하여 10품종 건조 고추의 일반특성(크기, 모양, 함량비)과 고추가루의 일반성분, 카로티노이드의 함량, Hunter색치(色値)를 측정하였고 100명의 주부를 선정하여 관능검사를 실시한 결과와 물리적, 화학적 측정치와의 관계를 비교하였다. Red carotenoid는 총 carotenoid의 68-85%를 차지하였으며 ${\beta}-carotene$ 함량은 관능적 선호도와 유의적인 상관관계를 나타냈고 Hunter 색차계(L,a,b,axL)의 값은 관능적 색선호도와 높은 상관관계를 나타내었다. 특히 axL값은 고추의 매운 강도 및 색 선호도와 높은 상관관계를 나타냈다. 따라서 고추가루의 소비자 선호도는 colorimeter에 의한 axL값에 의해 결정될 수 있다.
