项目摘要

The effects of the vegetarian diets on blood rheology in the middle-age women were investigated. The vegetarian diet consisted mainly of unpolished rice, bean curd, and green vegetables. The blood rheology were evaluated by measuring the flow time of the whole blood with a microchannel flow analyzer. The present study compared 33 women who were placed on a vegetarian diet for 6 weeks and 33 age-matched women (non-vegetarian control). The results of our dietary survey indicated that when compared to the control, the intakes of energy, and proteins were significantly lower in the vegetarian group, while those of calcium, retinal, isoflavones, kaempferol and total flavonoid were significantly higher. Regarding the changes in body physique, body composition, and blood pressure, all parameters except fat free mass in the vegetarian group decreased significantly after the start of the vegetarian diet. The levels of serum folic acid and plasma quercetin in vegetarian were significantly higher … More than those in control. The flow time of the whole blood in the vegetarian was significantly faster than that in control group. A principal component analysis was performed on the physique, body composition, hematological parameters, nutrient intake, and food intake for all individuals (35 vegetarians and 60 controls). Six components were extracted and subjected to multiple regression analysis. Two of the six components ; namely, "blood pressure and hematocrit value" and "serum proteins", were confirmed and accounted for 38% of variance in the flow time of the blood. The results of a path analysis showed that "blood pressure and hematocrit value" and "serum proteins" directly affected the blood rheology (flow time), while "hyperlipidemia", "obesity", "consumption of animal products", and "vegetarian diet" indirectly affected the blood rheology (r^2=0.38).These data suggest that the intake of the vegetarian diet stimulate the blood rheology and subsequently decrease the risk of impairing microcirculation.

本文探讨了素食对中年妇女血液流变学的影响。素食主要由糙米、豆腐和绿色蔬菜组成。用微通道流动分析仪测定全血流动时间，评价血液流变学。本研究比较了33名女性谁是放置在素食6周和33名年龄匹配的妇女（非素食对照）。膳食调查结果显示，与对照组相比，素食组的能量和蛋白质摄入量显著降低，而钙、视黄醇、黄酮、山奈酚和总黄酮的摄入量显著升高。至于体质、身体组成和血压的变化，素食组中除去脂质量外的所有参数在素食开始后均显著下降。素食者血清叶酸和血浆槲皮素水平显著高于 ...更多信息比那些控制。素食者的全血流动时间明显快于对照组。对所有个体（35名素食者和60名对照者）的体格、身体成分、血液学参数、营养素摄入量和食物摄入量进行主成分分析。提取了6个成分，并进行了多元回归分析。六个组成部分中的两个，即“血压和红细胞压积值”和“血清蛋白”，得到证实，并占血液流动时间方差的38%。通径分析结果表明，“血压、红细胞压积值”和“血清蛋白”直接影响血液流变学（流动时间），而“高脂血症”、“肥胖”、“食用动物产品”、素食间接影响血液流变学（r^2=0.38）。这些数据表明，素食的摄入刺激了血液流变学，从而降低了微循环受损的风险。少
