作者用酶消化的方法分离雪旺细胞（Schwanncell，SCs），比较了匀浆与否，及不同浓度的胰酶、胶原酶、胰酶／胶原酶混合液对不同材料所获分离SCs数量的影响。发现：1．不同酶的消化效果有一定的差异，其中胶原酶最好，胰酶／胶原酶混合液次之。2．浓度高的酶较浓度低者分离的细胞多。3．匀浆后用酶消化较不匀浆者效果好。4。匀浆后用酶消化，SCs数于20分钟时达到高峰；若不匀浆，酶消化30-40分钟SCs数才达到高峰。5．从脊神经节分离获得的SCs较坐骨神经者多。
Schwann cells (Schwann cells) were isolated by enzyme digestion, and the effects of homogenization or not, and the effect of different concentrations of trypsin, collagenase and trypsin / collagenase mixture on the number of SCs isolated from different materials were compared . Found: 1. Digestive effects of different enzymes have certain differences, of which the best collagenase, pancreatin / collagenase followed. 2. High concentration of enzyme concentration of the more cells isolated. 3. After homogenization enzyme digestion less homogenizer effect. 4. After homogenized and digested with enzyme, the number of SCs peaked at 20 minutes; if not homogenized, the number of SCs peaked 30-40 minutes after enzymatic digestion. 5. Scs derived from spinal ganglia were more sciatic nerve.
