Water-soluble ginseng oligosaccharides (WGOS) composed of D-glucose with a degree of polymerisation ranging from 2 to 14 were obtained from Panax ginseng C.A. Meyer. In this study, the anti-tumour and immunoregulatory effects of WGOS were evaluated in Hepatoma-22 (H22)-bearing mice. Treatment with WGOS inhibited tumour growth in vivo and significantly increased relative spleen and thymus weight, serum tumour necrosis factor-α level, spleen lymphocyte proliferation, natural killer cell activity, phagocytic function and nitric oxide production secreted by macrophage in H22-bearing mice. However, no direct cytotoxicity was detected. Therefore, the anti-tumour activity of WGOS may be related to their immunomodulatory effects.
从人参（Panax ginseng C.A. Meyer）中获得了由聚合度为2至14的D-葡萄糖组成的水溶性人参寡糖（WGOS）。在本研究中，对荷H22肝癌小鼠评估了WGOS的抗肿瘤和免疫调节作用。用WGOS治疗可抑制体内肿瘤生长，并显著增加荷H22肝癌小鼠的脾脏和胸腺相对重量、血清肿瘤坏死因子-α水平、脾脏淋巴细胞增殖、自然杀伤细胞活性、吞噬功能以及巨噬细胞分泌的一氧化氮产生。然而，未检测到直接的细胞毒性。因此，WGOS的抗肿瘤活性可能与其免疫调节作用有关。
