中分子量物质(MM)是指分子量在350—5000道尔顿间的混合物。Babb 等在观察不同血液透析条件下处理尿毒症患者过程中,认为该类物质能产生尿毒症毒性症状,从而提出了“中分子量物质”假说,目前认为,尿毒症患者中有心包炎,神经病变等并发症的出现和血浆中 MM 增高有关。由于采用一般血液透析对 MM 的清除不太理想,故有必要寻找其他治疗方法。近年来发 Medium molecular weight (MM) refers to a mixture of molecular weights between 350-5000 daltons. Babb and so on in the observation of different hemodialysis treatment of uremic patients in the process, that these substances can produce uremic toxicity symptoms, which proposed the “medium molecular weight” hypothesis, at present that uremic patients with pericarditis, neuropathy The emergence of complications such as increased plasma MM. Due to the general hemodialysis removal of MM is not ideal, it is necessary to find other treatments. In recent years sent
