多胺属于小分子碳氢胺类,在体外多胺与核酸有强亲和力,而在体内则可能具有控制 r-RNA 代谢的作用,它与细胞生长的很多方面均有密切关系,因而在迅速生长的组织中,多胺量可能有增加。Russell 报告,非肿瘤疾病患者尿中多胺排泄量与正常人无差异,而癌症病人除极少数病例外,尿多胺排泄量均有显著升高,达正常人的5—10倍。经有效治疗如手术切除,放疗化疗后共值均下 Polyamines are small molecule amines that have strong affinity to nucleic acids in vitro but may play a role in controlling r-RNA metabolism in vivo, and are closely linked to many aspects of cell growth and are thus rapidly growing The amount of polyamine may increase. Russell report, non-tumor patients with polyuria urinary excretion of urine and no difference in normal people, except for a very small number of cases of cancer, urinary polyamine excretion were significantly increased, up to 5-10 times normal. After effective treatment such as surgical resection, radiotherapy and chemotherapy after the average value
