用链脲霉素制备合格的糖尿病模型小鼠２４只，随机分为３组：对照１组为生理盐水组，对照２组为植入猪胰腺细胞组，治疗组为植入用免疫隔离膜包裹的猪胰腺细胞组。植入量均为１００ｍｇ。结果表明：治疗组小鼠在完全停用胰岛素的情况下，于第７天左右血糖水平可降至８．１１±３．０６ｍｍｏｌ／Ｌ并能维持２～４．５个月，与对照１、２组１９．６７±２．４５ｍｍｏｌ／Ｌ和１３。４４±２，５７ｍｍｏｌ／Ｌ相比均有显著差异（Ｐ＜０．０１；Ｐ＜０．０５）。可见免疫隔离膜具有良好的生物膜性，可以有效地避免宿主抗移植物的排斥反应，使猪胰腺细胞在小鼠体内仍具有生物功能。
Twenty four diabetic mice were randomly divided into three groups: control group 1 was saline group, control group 2 was implanted porcine pancreatic cell group, and the treatment group was implanted with immunosensorial membrane Porcine pancreatic cell group. Implantation volume is 100mg. The results showed that the blood glucose level of the mice in the treatment group decreased to 8.11 ± 3.06 mmol / L on the 7th day and maintained for 2 to 4.5 months after the complete withdrawal of insulin, There were significant differences between the two groups (19.67 ± 2.45mmol / L and 13.44 ± 2,57mmol / L) (P <0.01; P <0.05). It can be seen that the immunoisolating membrane has good biofilm property and can effectively prevent the rejection of the host against the graft, so that the porcine pancreatic cells still have biological functions in mice.
