脂质体是由磷脂及附加剂如胆固醇等在水中形成的单层和复层微球。它的直径一般在数百?到几个μ之间。脂质体能携带多种抗癌药物,并能控制药物的释放速度,改变原药物在体内的分布,增加药物的抗癌活性,降低药物毒副作用,还能避免药物在体内过快的降解或失活,因而脂质体是一种新型的药物载体,在肿瘤化疗上具有一定 Liposomes are monolayer and multilayer microspheres formed from phospholipids and additives such as cholesterol and the like in water. Its diameter is generally between a few hundred and several μ. Liposomes can carry a variety of anti-cancer drugs, and can control the release rate of drugs, change the distribution of the original drug in the body, increase the anti-cancer activity of drugs, reduce drug side effects, but also to avoid excessive degradation or loss of drugs in the body Live, so liposomes are a new type of drug carrier and have a certain degree of chemotherapy in cancer
