Platelet function and phospholipid composition, plasma lipids and dietary intakes were assessed in 20 vegan subjects and 20 age- and sex-matched omnivore controls. The intakes of saturated fat were lower in the vegans and those of linoleic and linolenic acids were greater. Eicosapentaenoic and docosahexaenoic acids were absent from the diets of the vegans. Plasma total cholesterol and low-density lipoprotein concentrations were lower in the male vegan subjects and those of carotene were greater compared with their controls. The platelet phospholipids of the vegans contained higher proportions of linoleic (18:2n-6) and adrenic (22:4n-6) acids and lower proportions of arachidonic (20:4n-6), eicosapentaenoic (20:5n-3), docosapentaenoic (22:5n-3) and docosahexaenoic (22:6n-3) acids. Template bleeding times, platelet aggregation induced by adenosine diphosphate, compound U44619 and collagen were similar in both groups.
对20名纯素食受试者以及20名年龄和性别相匹配的杂食对照者的血小板功能与磷脂组成、血浆脂质及饮食摄入量进行了评估。纯素食者饱和脂肪的摄入量较低，而亚油酸和亚麻酸的摄入量较高。纯素食者的饮食中不含二十碳五烯酸和二十二碳六烯酸。与对照组相比，男性纯素食受试者的血浆总胆固醇和低密度脂蛋白浓度较低，而胡萝卜素浓度较高。纯素食者的血小板磷脂中，亚油酸（18:2n - 6）和肾上腺酸（ adrenic ，22:4n - 6）的比例较高，而花生四烯酸（20:4n - 6）、二十碳五烯酸（20:5n - 3）、二十二碳五烯酸（22:5n - 3）和二十二碳六烯酸（22:6n - 3）的比例较低。两组的模板出血时间、由二磷酸腺苷、化合物U44619和胶原诱导的血小板聚集情况相似。
