在患癌动物所见到的血清 Zn 值的下降,有以下三种原因。一是因血清中的 Zn 值,约70%与白蛋白结合,故认为 Zn 值降低是血清白蛋白下降的继发性改变:二是患癌机体的肝含 Zn 量增加,故认为是由于 Zn 从血清向肝的移行亢进所致;三是许多恶性肿瘤含有大量的Zn,故认为可能是血清中的 Zn 聚集于肿瘤细胞所致。根据这些观点,就胃癌患者血清 Zn 值与白蛋白值、肝转移的关系进行了研究。据说 Zn 也有向人胃癌组织聚
There are three reasons for the decrease in serum Zn seen in cancer-bearing animals. First, about 70% of albumin is bound to albumin due to Zn in serum. Therefore, it is considered that the decrease in Zn value is secondary to the decrease in serum albumin. Second, the amount of Zn in the liver of the cancerous organism is increased. It is considered that this is due to Zn. From the serum to the liver due to hyperthyroidism; Third, many malignant tumors contain large amounts of Zn, it is thought that serum Zn may be caused by the accumulation of tumor cells. Based on these points of view, the relationship between serum Zn levels in patients with gastric cancer and albumin values and liver metastases was studied. It is said that Zn is also accumulated in human gastric cancer tissues.
