| dc.description.abstract | 副甲狀腺機能不足症為目前難以完全治癒的內分泌疾病之一，在臨床上也並不建議在副甲狀腺異體移植後使用全身性免疫抑制的藥物，故使用具半通透性的膜來包覆副甲狀腺組織再進行異體移植，來達到植入組織在病人體內具有免疫隔離的效果。本研究使用氧化幾丁聚醣交聯昆布胺酸，將副甲狀腺組織塊外面包覆後滴入三聚磷酸鈉溶液中，利用離子吸附的方式在組織塊外圍成一層膜狀的水膠。在材料測試方面，氧化幾丁聚醣/昆布胺酸水膠在體外28天內可維持約80 %重量與型態，且具有良好的生物相容性，同時不具細胞毒性。以材料包覆組織後進行體外培養結果，組織外的膜狀水膠可使人類副甲狀腺素成功釋放至環境中，證實包覆材料並不會影響組織的分泌功能，並大致具有隨周圍環境的鈣離子濃度調整釋放量的趨勢，且在組織切片的觀察結果顯示包覆材料並不影響具分泌能力的主細胞的存活。在動物實驗方面雖有成功導致實驗動物具有副甲狀腺機能不足症，但在移植之後的組織對血鈣濃度的調節效果並不如預期，顯示本實驗模型還有待改進。 | zh_TW |
| dc.description.abstract | Permanent hypoparathyroidism is one of the endocrine disorders that are difficult to treat medically. Since hypoparathyroidism rarely is a life-threatening condition, systemic immunosuppression for recipients of allo-transplants are not justified. Coating the allo-transplanted tissue with a semipermeable membrane to protect the tissue from immune rejection is an alternative. In this study, oxidized chitosan cross-linked with laminin is prepared for microencapsulation of parathyroid tissue fragments. The parathyroid tissue particles with oxidized chitosan/laminin are dropped in sodium tripolyphophate solution. Tripolyphophate ion, the polyanion, would interact electrostatically with the cationic chitosan and become hydrogel to enclose the tissue particle. In the material analysis, oxidized chitosan/laminin hydrogel maintained about 80 % mass and it’s morphology in PBS until the 28th day. The material in vitro tests also showed that hydrogel had good biocompatibility and low cytotoxicity. The microencapsulation of parathyroid tissue in vitro study revealed that the hydrogel was freely permeable to the human parathyroid hormone and responded to different calcium concentration in the ex vivo test. The histological evaluation showed that the capsular hydrogel membrane were not affective to the chief cells which are the main secretory cell in the parathyroid glands. In animal study, hypocalcemia rats were induced successfully but the encapsulated tissue particles implanted were not functional in vivo. The result demonstrated that the animal model in this study must be improved. | en |
