The t-BN powder was analyzed by XRD, SEM and laser granularity analyzer.
用XRD、SEM及激光粒度分析等手段对所制各级化硼粉体进行研究。
Conclusion: Chimerism and immune tolerance can be induced by Cyclophosphmide and when the grafted skin was rejected, the ratio of t cells from BN significantly decreased.
结论：环磷酰胺可诱导嵌合免疫耐受的产生，在嵌合状态下可检测到供鼠来源的T细胞。当移植皮肤被排斥时，供鼠来源T细胞占总t细胞的比例显著降低。
