[美国《医学世界新闻》报道] 肝脏具有很强的再生能力。将实验动物的肝脏切除80％甚至90％,整个器官也将会再生。在人体亦如此。将患者的肝脏切除90％,在数月内几乎重新长全。虽然肉眼看来再生的组织并无正常的外观,胆显微镜下看来是和原先的组织很相似的。为什么切除的肝脏能重新生长,而正常的肝脏不会再生呢?某些研究者认为,在门静脉血中必定存在一种使肝脏再生的特殊因素。现在已弄清楚,在内脏循环,特别是在胰腺或十二指肠中存存一种物质或多种物质。此物质的性质尚不清楚,但它的分子量一定是小于12,000,一般认为是一种激素。
[Report from Medical World News] The liver has strong regenerative capacity. The experimental animal liver resection 80% or even 90%, the entire organ will also be regenerated. The same is true in the human body. The patient’s liver was resected 90% and almost completely renewed within a few months. Although it appears to the naked eye that the regenerated tissue has no normal appearance, it appears to be very similar to the original tissue under the gall bladder microscope. Why does the resected liver regrowth, and the normal liver does not regenerate? Some researchers believe that there must be a special factor in the portal vein to regenerate the liver. It has now been clarified that a substance or substances are stored in the visceral circulation, especially in the pancreas or duodenum. The nature of this substance is not clear, but its molecular weight must be less than 12,000, which is generally considered a hormone.
