    論文的最後一章中，我們合成了具有較好的電子傳輸性能的化合物』一二苯基四竣酸花酚亞胺（ ddp ） ；研究了其溶解性、熱穩定性、晶體結構、紅外光譜、紫外吸收光譜和蒸鍍薄膜的屬性，並用量子化學計算方法模擬其單分子的空間構型；載流子遷移率測試的結果約為ix10 「 、 m 』 v 」 』 ? s 「 』 。
  18. Here we managed to make cultured mice peritoneal macrophages be directly influenced by oligochitosan, and be stimulated by ifn - r before oligochitosan added, then measured the changes of gene transcription and translation level of both il - 1 and imf - a, respectively by methods of relatively quantitive rt - pcr and elisa. first, rt - pcr results showed that 18 hours was the most effective time and 40ug / ml was the most effective concentration of oligochitosan, then by the same method, confirm that 4hours is the most effective time and loou / ml is the most effective concentration of ifn - r stimulating. because ifn - r can enhance il - 1 and tnf - a gene expression of macrophages alone, so add ifn - r to microphages alone for 22 hours, then examined by rt - pcr, the results showed that il - 1 and tnf - a gene expression have no remarkable difference compared with the blank contrast group

    此外，由於ifn y單獨作用也可促進兩種細胞因子基因表達，故在巨噬細胞中加入ifn y單獨作用22h ，再經阿一pcr檢測，發現加ifn y的實驗組細胞的幾一lp和tnf a基因轉錄水平與空白對照組相比較無顯著性差異，可見，殼寡糖和ifn v對巨噬細胞il lp和tnf一口基因轉錄水平的影響在作用時間上無一致性，在殼寡糖作用最適時間時，僅受ifn y刺激的巨噬細胞il lp和tnf q基因轉錄己下降至刺激前水平，因此可以認為， ifn y的加入僅起到對巨噬細胞預刺激使之處于敏感狀態的作用，有利於增強殼寡糖對巨噬細胞的作用。
