必需脂肪酸，诸如亚麻酸（GLA）和二十碳五烯酸（EPA）对治疗癌肿有些效果，GLA的俚盐（Li－GLA）对人体胰腺癌的生长有抑制作用，可抑制不可切除的胰腺癌生长，但其在体内的机制不明，为此进行下列实验。取BALB／C裸鼠作实验，在左胁皮下种植人体胰腺癌MIAPaCa2细胞105个，或 Essential fatty acids, such as linolenic acid (GLA) and eicosapentaenoic acid (EPA), have some effect on the treatment of cancer, GLA’s guanidinium salt (Li-GLA) inhibits the growth of human pancreatic cancer and can inhibit unresectable Pancreatic cancer grows, but its mechanism in the body is unknown, for which the following experiments were performed. BALB/C nude mice were used for the experiment. 105 human pancreatic cancer MIAPaCa2 cells were implanted under the left flank, or
