The microspheres and conventional MMC were infused into the hepatic artery of dogs through a catheter for embolization,respectively.The plasma concentration of MMC was de- termined by HPLC.Results showed that the peak concentration of conventional MMC was 2.6 times as much as MMC-DMS.Angiograms revealed that peripheral blood vessels de- creased obviously in liver.The histopathologic examination showed that the microspheres lodged in the hepatic artery and displayed nodular necrosis in the embolized segment.The MMC-DMS were used in clinical trial in 100 patients with hepatic cancer.The tumor reduc- tion and improvement of symptoms in patients were observed after hepatic arterial embolization.The survival duration was prolonged.Results showed that the MMC-DMS is a promising embolic agent for treatment of hepatic cancer.It could aid in the use of intensive chemotherapy with minimum systemic side effect.展开更多
目的:评价联合应用丝裂霉素 C 和可调整缝线的小梁切除术治疗闭角型青光眼的效果。方法首次接受小梁切除的病例52例(52眼),术中丝裂霉素C的浓度为0.2~0.4mg/mL,时间为2~4min,巩膜瓣两侧做2条可调整缝线。临床观察指标包括术后眼压...目的:评价联合应用丝裂霉素 C 和可调整缝线的小梁切除术治疗闭角型青光眼的效果。方法首次接受小梁切除的病例52例(52眼),术中丝裂霉素C的浓度为0.2~0.4mg/mL,时间为2~4min,巩膜瓣两侧做2条可调整缝线。临床观察指标包括术后眼压、滤过泡、前房及并发症。结果所有病例平均随访(8.94±1.21)月,术后各时期的眼压与术前眼压比较均明显下降;无低压性黄斑病等严重并发症出现。结论青光眼小梁切除术中应用丝裂霉素C联合可调整缝线可以有效地降低患者的眼内压,稳定前房,减少术后并发症。展开更多
