Abstract:
AIM and METHODS: After the fine carbon fiber powder was injected into the right subdural space of the mice, dynamic observation was carried out on their movement and histopathological changes. RESULTS: 1-52 weeks after the injecting, no neurological changes concerning with the implanting of the carbon fiber powder were found in the experimental mice. The fine carbon fiber extensively located on the inter surface of the dura mater membrane of the right temporalis and the out surface of pie mater. Only slight inflammatory cells reaction was found under optical microscopes. The degree of inflammation reaction are Grade Ⅱ 1 week after injection and was Grade Ⅰ 2 weeks after injection, inflammation was disappeared 4 weeks after injection. No obvious fiber membrane was found around the implanted materials. No significant differences were found between the experimental and the control group.CONCLUSION: It was showed that the carbon fiber shares excellent histocompatibility after injected into the subdural space and subarechnoid cavity of the right temple of mice.
