在接种高转移性人肺腺癌细胞株的裸鼠膳食中分别加入８种脂肪酸，即分成８个实验组，另设对照组（ｎ＝６）。饲养３０天后处死，观察转移率和转移特征。结果表明，多数组，特别是不饱合脂肪酸组对肿瘤转移率无明显影响，转移率均在９０％以上，仅Ｃ１６∶０的转移率为５０％，同对照组相比差异显著。 Eight kinds of fatty acids were added to the diet of nude mice inoculated with highly metastatic human lung adenocarcinoma cell lines, which were divided into 8 experimental groups and control groups (n=6). After 30 days of feeding, they were sacrificed and the metastasis rate and metastatic characteristics were observed. The results showed that most of the groups, especially the unsaturated fatty acid group, had no significant effect on the tumor metastasis rate. The metastasis rate was above 90%. Only the C16:0 metastasis rate was 50%, which was significantly different from the control group.
