Section two the evaluation of biocompatibility of the acellular dermal matrix by the method of cell culture. the new born rat ' s epdermic cells were cultured with the acellular dermal matrix together as experiment group, while the epdermic cell were cultured simply as control. 24 hours later, under the invert microscope, the epidermic cells anchored well and transparent flat cells were observed in both groups. 7 days later, both cultured cells were taked out and fixed in 95 % ethanol, stained with hematoxylin and were observed under light microscope. many cleaved cells were observed in both groups. during cell culture, no pathogenic microganism was observed. so we considered the acellular dermal matrix was aseptic and had good biocompatibility. section three subdermal implantation of the acellular dermal matrix. 24 rats were used in the experiments. a piece of acellular dermal matrix ( 1. 5 x 1. 5cm2 ) was implanted beneath the dorsum skin flaps of each rat, 1 week, 2 weeks, 3 weeks and 4 weeks after implantation, 6 pieces of acellular dermal matrix were harvested and the size of implanted acellular dermal matrix were measured, the sections were used for he staining and observed under light microscope. the result were as folio wing : 1 - 2 weeks after implantation, the acellular dermal matrix began to adhere to the tissue around and turned red gradually ; 3 - 4weeks after implantation, the acellular dermal matrix adhered closely to the tissue around and could be recognized easily, 1 - 3 weeks after implantation, the size of implanted acellular dermal matrix had no statistical difference ( p > 0. 05 ). 4 weeks after implantation implanted acellular dermal matrix contracted ( p < 0. 05 ). under light microscope, l - 2weeks after implantation, the fibroblast cells infiltrated the acellular dermal matrix and a small amount endothelial cells of vessel and lympho - histiocytic cells infiltrated the acellular dermal matrix. 3 - 4 weeks after implantation, infiltrating blood vessels were evident. so we think that the acellular dermal matrix had low immunological reactions and could induce the infiltration of fibroblast macrophage cell and the endothelial cells of vessel

但是，學者們發現這一療法存在著如下的缺陷：單一ctl表位抗原肽的應用其抗腫瘤作用弱於多種腫瘤抗原的聯合應用，且有誘導免疫耐受的潛在危險，有時反而會促進腫瘤的生長；事先需對患者的hla單倍型進行鑒定，以確定ctl表位與hla單倍型是否匹配，目前尚缺乏能與所有hla單倍型相匹配的ctl表位，從而限制了這一療法的應用；這一療法所產生的ctl在體外能有效殺傷經腫瘤抗原肽共孵育過的靶細胞，但對腫瘤細胞的殺傷能力較弱：這種l表位抗原肽缺乏cd4汀h細胞相關的表位，因此，不能誘導有效的th細胞免疫應答。Abstract : the crystal structures obtained by static solidification and vibration solidification were compared. it was showed that, in the case of vibration solidification, the orientation growth of the columnar crystal was not obvious, the equiaxial crystal appeared more early. the grains of both types of crystals were quite fine, hardness in the full section was relatively high, and the hardness distribution was uniform. in the former case, the solute segregation in dendritical austenite more severe, and there were lumps of distortion inclusion
