Binding of urokinase-type plasminogen activator to its cellular receptor accelerate production of plasmin from plasminogen on the cell surface. Plasmin can digest extracellular matrix components and basement membranes through activating certain proMMPs, which is related to the invasiveness to the cells. Plasmin also acts the regulation of blood coagulation and relates closely to cardiovascular diseases such as stroke and coronary occlusion. Therefore, its inhibitors may be useful as antimetastatic agents and to the treatment of cardiovascular diseases. To search for plasmin inhibitors from plant resources, we screened plasmin inhibitory activities with 76 methanol extract of plant species. Among them, three plant samples showed strong inhibitory activities (>70%) and thirteen plant samples showed more than 50% inhibitory activities of plasmin. Their inhibitory activities were not directly related with uPA inhibitory activites and cell viability.

생식의 섭취가 실험동물의 길이성장 및 균형성장에 미치는 효능을 평가하기 위하여 12주간 생식을 1g/kg/day(1xJS), 2g/kg/day(2xJS) 및 4g/kg/day/(4xJS)의 용량으로 경구투여한 후 처치시점 4주, 8주 및 12주에 각각 희생시켜 성장에 관련된 요인들을 측정하였다 실험동물의 식이섭취량, 체중증가량 및 장기무게는 생식을 경구투여한 실험군과 대조군 간에 유의적인 차이가 없었으며, 공복 시 혈중 AST와 ALT의 농도 역시 군 간에 유의적인 차이를 보이지 않았고 모두 정상수치를 기록하였다. 실험동물의 신장 및 대퇴골 길이의 변화는 12주간의 실험기간 중 생식을 경구투여한 실험군이 대조군에 비하여 평균적으로 증가하였으며 특히, 처치시점 12주에서는 신장과 대퇴골 길이의 변화가 생식을 경구투여한 모든 실험군이 대조군에 비하여 유의하게 증가한 것으로 관찰되었다. BMD와 BMC의 결과에서도 BMD의 경우 4xJS군, BMC의 경우 1xJS군과 4xJS군이 대조군에 대하여 유의한 증가를 나타내었으나, 생식 투여량에 대한 농도의존적인 경향은 나타나지 않았다. 또한, 성장인자의 하나인 혈중 IGF-1의 경우 처치시점 4주에서 생식을 경구투여 한 모든 실험군이 유의적인 증가를 나타내었으며, 8주 이상에서는 4xJS군에서만 유의적인 증가가 나타났다. 이상의 결과에서 성장기에 장기적인 생식의 보충 섭취는 실험동물의 골성장을 통한 성장 발육에 도움을 준 수 있을 것으로 사료된다. This study was performed to investigate the effect of long-term administration of Saengshik on growth parameters of growing rats. Male Sprague-Dawley rats were fed on AIN-93G basal diets for 12 weeks and assigned to the following groups: rats administrated orally with Saengshik at the dose of 1g/kg/day (1xJS ), 2g/kg/day (2xJS), 4g/kg/day (4xJS) and distilled water (Control). Rats were sacrificed at 4, 8, 12 weeks after oral administration. Bone mineral density (BMD) and bone mineral contents (BMC) were measured by PIXImus densitometry and serum insulin-like growth factor-1 (IGF-1) concentration were determined by using EIA method. Body weight and food intake did not show significant changes within groups for 12 weeks. Physical longitudinal growth indexes, body length and femur length were significantly increased in Saengshik-administered groups at 12 weeks, in which BMD and BMC also significantly increased. Also, in blood IGF-1 level, Saengshik-administered groups were remarkedly higher than control group at 4 week (p<0.001), in which significantly higher at 8 week and 12 week. These results suggest a close relation between administration of Saengshik and increment of longitudingal bone growth. Therefore, as the result of this study, it could be expected that the administration of Saengshik for 12 weeks is helpful to the increase of longitudinal growth and growth factors in rats. Furthermore, we propose that the consumption of Saengshik as dietary supplementation may promote to increase in longitudinal bone growth in growing children.

This study was performed to investigate dietary behaviors and consumption of health food in cancer patients. The subjects were 163 cancer patients recruited from the general hospital in Seoul, Korea. The data were obtained by the structured self administered questionnaire. The mean age of subjects was 51 years. Most of subjects didn't eat the visual fat of meat and chicken skin. The mealtime of the subjects was generally regular and most of subjects had breakfast. The subjects of this survey liked to eat foods with sweet taste but disliked to eat hot, salty and sour taste ones. The preference for fish, marine products and vegetables was high but that for instant foods and frying foods was very low. Most of subjects consumed the foods that is generally known as anticancer foods such as vegetables and fruits. On the other hand, most of subjects didn't intake butter, margarine, and frying foods that is known as risk factors of cancer. The majority of subjects$(84.7\%)$ consumed the health food The main reasons for taking health foods by subjects were to cure disease$(58.0\%)$, to prevent disease$(45.3\%)$, to supply nutrients$(39.3\%)$, to maintain the mental state$(12.7\%)$ and to recover fatigue$(10.7\%)$. Majority of subjects$(66.0\%)$ spent money more than 200,000 won/month to buy health foods. The purchasing channels of health foods by subjects were recommendation by family or friend$(64.0\%)$, by physician/pharmacist$(18.0\%)$ and by nutritionist or dietician(6.0), and advertisement through TV or radio$(12.0\%)$. The types of taking health foods of the subjects were vegetable extracted food$(60.0\%)$, mushrooms$(51.3\%)$, Lactobacillus food$(25.3\%)$, enzyme food$(22.6\%)$ calcium containing food$(20.0\%)$ and so on. The results of the current study show that although many cancer patients already practice healthy dietary behaviors, there is a substantial proportion who do not and most of cancer patients consume health foods.' Further intervention is needed to explore the effect of health foods in cancer patients

임병우(Beong Ou Lim),정용준(Yong Jun Jeong),박미현(Mi Hyoun Park),김종대(Jong Dai Kim),황성주(Sung Joo Hwang),유병팔(Byung Pal Yu) 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.1

본 연구의 목적은 DSS로 유발시킨 대장염 동물모델에서 생식섭취가 장관 내 면역조절에 미치는 영향에 대하여 검토해보고자 했다. 그 결과, 생식섭취가 DSS로 유발시킨 대장염에서 normal군보다 IFN-γ의 함량을 증가시키고, IL-4와 IL-10의 함량은 감소시킴이 관찰되었다. 또한, 증가된 Th1 세포의 cytokine과 감소된 Th2 세포의 cytokine은 염증이 유발된 후, 생식을 통한 치료로써 변환시킬 수 있음을 증명하였다. 이러한 연구 결과를 볼 때 DSS로 유발시킨 대장염에서 생식섭취를 통한 치료는 IL-4와 IL-10과 같은 염증성 cytokine의 억제기능을 통하여 면역시스템을 강화시키고, 손상된 염증을 완화시켜 줄 것으로 판단된다. 생식의 면역조절에 관한 자세한 기전은 아직 밝혀져 있지 않지만, 염증성장질환에서 생식섭취가 면역학적 역할에 대한 새로운 양상들에 대한 연구가 더욱더 필요할 것으로 사료된다. This study was conducted on the immunoregulatory effect of Saengshik on gut-associated lymphoid tissue with inflammatory bowel disease. Although the contents of IgA increased in mesenteric lymph node, IgE con-tent was suppressed by Saengshik. The same results were found in spleen, but IgA and IgE responses were very weak. Concentration of fecal IgA was high from the first day through the third day in Saengshik group. In DSS+Saengshik group, concentration of IgA was high till the 2nd day and it maintained the highest level among the test groups on the 5th day. Concentration of IFN-gamma and IL-2 was the highest in the Saengshik group, but the concentration of TNF-alpha was lower in DSS+Saengshik compared to DSS. The expressions of STAT1 in Saengshik group were high, while those of STAT6 were low. According to these findings, Saengshik exhibited effectiveness via increasing the IgA production, suppressing the IgE production, followed by inhibiting the production of IL-4 and IL-10. Saengshik also strengthened the immune system and alleviated injury in DSS-induced inflammation.

본 연구는 생식을 정상성인에게 섭취시켰을 때 혈당반응에 미치는 영향을 연구하고, 생식의 혈당지수를 구하여 당뇨병 환자의 혈당 조절식으로 이용가능성을 조사하기 위하여 시판중인 생식 4(ES, HS, BS, SS)종을 섭취 전, 섭취 후 120분 동안 15분 간격으로 채혈하여 혈당을 측정하였다. 생식섭취 후 혈당수치는 포도당 섭취시보다 전반적으로 낮게 나타났으며, ES는 15~75분, SS는 15~75분, HS는 15~45분, BS는 15분 후의 혈당이 포도당보다 유의적으로 낮게 나타났다. 식이 섭취 후 측정한 시간에 따른 혈당값을 이용하여 혈당반응 곡선의 면적을 구한 결과, 생식 섭취군은 포도당 섭취군보다 면적이 적은 것으로 나타났으며, 상기 면적을 이용하여 GI를 산출한 결과, ES는 43.1±12.6으로 Low GI(55이하) 범위에 속하였으며, 그 외 생식은 Medium GI(56~69) 범위에 속하였다. 생식의 소화, 흡수 형태를 알아보기 위하여 상기에서 구한 혈당반응곡선 면적을 일반적인 최고 혈당값 나타내는 시간인 30분을 전후로 하여 LAR(혈당상승기)과 RAR(혈당감소기)을 구한 결과, 생식은 혈당 상승과 감소를 완만하게 해주는 것으로 나타났으며, 생식섭취 후 최고 혈당값을 포도당을 섭취했을 때보다 유의적으로 감소 시켰으며, 최고 혈당값을 나타내는 시간은 생식 ES에서 연장되는 경향을 나타내었다. 위의 결과들을 종합해 볼 때, 생식의 섭취는 체내 당의 소화와 흡수 과정을 천천히 진행시키며, 식후 최고 혈당수치를 감소시켜 전반적인 혈당반응을 원만하게 하는 것으로 나타났으며, GL은 ES(14.1)이 가장 낮았으며 HS, BS, SS(19.2~19.5) 수준으로 GL 역시 낮은 수치를 나타내었다. 위의 연구결과 생식은 당뇨병 환자의 식후 혈당상승을 조절하여 유익한 영향을 미칠 수 있을 것으로 사료되며, 생식의 조성에 따라 그 효과는 차이를 보이며, 사용하는 당의 특징과 곡류군의 조성, 식이섬유의 종류, 과일소재의 첨가 등에 따라 달라지므로 추후 심화된 연구가 필요할 것이다. The purposes of this study were to investigate the effect of Saengshik on blood glucose level of normal subject and to explore the marketing possibility of four kinds of Saengshik (ES, HS, BS, SS) as alternative diabetic meals. Blood glucose levels of healthy volunteers was measured at 15, 30, 45, 60, 75, 90, 105 and 120 minutes after taking Saengshik and 50 g glucose. Blood glucose response areas, glycemic index (GI) and glycemic load (GL) were calculated from the glucose response. The Saengshik showed a significantly lower glucose level than the glucose. The glycemic index (GI) of ES showed 43.1±12.6, which belonged to low GI foods (GI of 55 or less). Other samples (HS, BS, SS) could be classified as intermediate GI foods ranging 56~69 of GI. Saengshik showed a gentle rising and falling pattern showing moderate left area ratio and right area ratio on blood glucose curve. The GL of ES showed 14.1 while HS, BS and SS did 19.2~19.5. The results indicated that Saengshik may have a beneficial effect on a diabetic.
