Among them, lyophilized human dura mater with good histocompatibility and less complications is applied most widely. But there are a few reports on cases of infected spongiform encephalopathy following application of lyodura. More ideal repair materials deserve to be further investigated. OBJECTIVE： To investigate the efficiency and safety of biological dural graft made by meninges from porkers to repair meningeal injury. DESIGN： A self-control observation. SETTING： Wuhan General Hospital of Guangzhou Military Area Command of Chinese PLA. MATERIALS： Sixteen New Zealand Rabbits, of either gender, weighing from 2 to 3 kg, of clean grade Ⅱ, with the age of 0.5 - 1 year, were involved in this experiment. The involved rabbits were provided by the Animal Experimental Center of the First Military Medical University of Chinese PLA. Biological surgical patch （dural graft） was developed by Guangdong Guanhao Biotechnological Co.,Ltd. It was processed by using meninges from porkers by tissue engineering technology. METHODS： This experiment was carried out in the Experimental Center of the 157 Hospital of Chinese PLA between December 2003 and June 2004. ①The experimental rabbits were anesthetized. Dura mater was exposed from two sides ofpostmedial line of coronal suture. A rectangular dura mater about 8 mm ×8 mm in size was cut off. Then a biological surgical patch （dural graft） was sheared into insert with 8 mm diameter and sutured. The left dura mater was untouched and used as control. Scalp was sutured, and postoperative wound healing and recovery were observed. ②The anesthetized rabbits were sacrificed at postoperative 3, 14, 30 and 90 days, 4 rabbits once. The whole head was cut off, and its scalp was removed. Afterwards, the head was fixed by formalin. Tissues in operative site were obtained, performed routine paraffin embedding, sliced and conducted HE staining, finally, the sections were observed. Whi展开更多
