周围神经再生的微环境(Microenvirome-nt)是近十年来出现的新概念,指的是周围神经损伤修复后,能否成功地再生主要取决于是否具有适合其生长的微环境条件。虽然目前对这种微环境的认识还很不完全,但已了解到微环境中含有多种物质成份,对再生神经的生长和走向起着十分重要的营养和诱导作用。国外近年来对此进行了一系列研究,现将有关问题综述如下。一、微环境的有关概念aguayo曾在实验中将大白鼠的视神经切断,然后桥接一段长30mm的自体坐骨神经,发现近端视神经的再生纤维能够长入周围神经 Microenvirome-nt is a new concept that has emerged in recent ten years. It refers to whether the successful regeneration after peripheral nerve injury repair mainly depends on whether it has microenvironmental conditions suitable for its growth. Although the current understanding of this microenvironment is still incomplete, it has been learned that the microenvironment contains many substances and plays an important role in nutrition and induction of the growth and development of regenerative nerves. In recent years, foreign countries conducted a series of studies on this issue. The relevant issues are summarized as follows. First, the concept of microenvironment aguayo Experiments in the optic nerve of rats cut off, and then bridge a length of 30mm of the autologous sciatic nerve and found that the proximal optic nerve regenerated fibers can grow into the peripheral nerve
