聚丙烯酰胺凝胶的组织相容性实验

目的：对比研究国产及进口聚丙安的组织相性。方法：选用昆明小白鼠３２只，随机分为３组４个时期分别在小白鼠皮下及肌内ｍＬ国前及进口聚丙烯酰胺，并以生国水作空白对照，分期观察２种材料的组织现理改变，结果：２种聚丙烯酰胺注入鼠皮下或肌肉内不引起急性或亚急性早物排斥反应，注入部位可很快形成纤维包膜将注入物包裹，结论：国产聚丙安及进口产品具有相同且良好的生物相容性。

Experiment of histocompatibility of polyacrylamide gel

AIM: To study the histocompatibility of polyacrylamide and to compare imported polyacrylamide with native one. METHODS: 32 Kunming species mice were divided into 3 groups. The 0.5 mL of imported and native polyacrylamide were separately injected into subcutaneous tissue and muscle in 4 different periods. The normal saline was used for the control. The tissues were obtained for pathological observation in different stages. RESULTS: Neither acute nor subacute foreign material reject reaction was found after the gel was injected in tissue. The gel was wrapped up rapidly by the fibrous capsule. CONCLUSION: Both the native and imported polyacrylamide shows the satisfied biocompatibility.
