In the average 8.1-month follow-up period, the visual acuity, graft transparent duration and Rejection Index (RI) of grafts were observed. Results: In the follow-up period, the graft rejection rate of the experimental and the control group was 63.6% and 95.2% respectively (χ2=4. 72, P < 0. 05) with significant difference.Conclusions: The local application of FK-506 suppressed effectively the graft rejection of corneal transplantation of the patients at high risk.展开更多

文摘目的 研制可植入玻璃体的FK506控释药膜,并评价其在兔玻璃体腔内的释药动力学过程及毒副作用。方法 HPLC/MS/MS法测定FK506控释药膜植入玻璃体后3个月内眼内组织及全血中的FK506浓度,观察该药膜植入兔眼后1个月内的毒性反应。结果FK506控释药膜植入兔玻璃体3个月内,玻璃体的平均药物质量浓度为41.57ng/ml,而全血中仅为0.25ng/ml。裂隙灯显微镜、ERG及组织学检查均显示FK 506控释药膜植入兔眼后1个月内未发生局部毒性反应。结论 可植入性FK506控释药膜植入兔玻璃体后,以较恒定的速率释放FK 506,使眼内组织在较长时间内维持较稳定的 FK 506浓度。兔眼对 FK 506控释药膜表现出良好的耐受性。
