为了将微囊包膜技术应用于垂体移植，本文采用海藻酸钠包裹混合的胎垂体下丘脑黑质细胞，通过测定微囊细胞培养液中生长激素（ＧＨ）与泌乳素（ＰＲＬ）分泌水平、促甲状腺素释放激素（ＴＲＨ）刺激ＰＲＬ分泌试验及用微囊细胞免疫兔等方法，发现微囊细胞分泌活性良好，微囊内垂体细胞功能受到下丘脑细胞分泌因子的调节，且ＰＲＬ分泌受到控制；微囊膜能通透垂体激素与下丘脑因子，并具有免疫隔离作用。结果提示：本微囊可作为具有免疫隔离性能的移植物．可在颅外移植而垂体细胞功能仍能正常发挥，同时能避免移植后高泌乳素血症发生。
In order to apply the technique of microencapsulation to pituitary transplantation, we mixed the mixed pituitary hypothalamic substantia nigra cells with sodium alginate and measured the secretion of growth hormone (GH) and prolactin (PRL) TRL stimulation of PRL secretion test and the use of microcapsules and other methods of immune rabbit and found that the secretion of microcapsules good cell activity in the microcapsule pituitary cells regulated by hypothalamic cells secretion factor and PRL secretion under control ; Microcapsule membrane can permeate pituitary hormone and hypothalamic factor, and has immune isolation. The results suggest that: The microcapsule can be used as a graft with immunosuppressive properties. Can be transplanted in the extracranial and pituitary cell function can still be normal play, at the same time to avoid hyperprolactinemia after transplantation.
