以正常人肝、肝细胞癌及癌周肝组织为样品,制备神经节苷脂并经唾液酸定量和高效硅胶薄板层析分析发现:人肝癌组织中GM1、GD3、GD1a和GQ1b的比例增高数倍,而正常主要组织的GM3相对减少,样品的个体差异明显。采用混合肝癌组织膜片 Gangliosides were prepared from normal liver, hepatocellular carcinoma and peritumor liver tissues by quantitative and high-performance silica gel thin-layer chromatography. The results showed that the proportion of GM1, GD3, GD1a and GQ1b in human hepatocellular carcinoma increased Times, while the GM3 of the normal main tissues decreased relatively, and the individual differences of the samples were obvious.
