they tended te increase yvith an increas;ng dietary oteate Nevel. A hypotriglyceridemic trend vvas obseryed toward an increasing proportion of oleic acid. The linoleate desaturfttion index, (dihomo-7-linolenic acid+arachidonic acid)flinoleic acid, in tiss"e phosphatldylcholine tended to increase vvith an incrcasing proportion of oLeate, whereas the productiofi of prestacyclin by the aorta and thromboxane A, by ptatelets was independent of the dletary oleate level. These results ind;cate that dietary oleate did not significantly modify the effect of polyunsaturated fatty acids on various
