膜壳

Chitosan-L-lactic acid composite asymmetric membrane for the regeneration of peripheral nerve was obtained by grafting L-lactic acid onto the amino groups in chitosan without any chemical initiator combined vacuum freezer drier.

摘 要：对不使用任何化学引发剂在真空下使壳聚糖与L-乳酸接枝共聚进行研究，结合真空冷冻干燥工艺制备一种用于周围神经再生的复合不对称膜材料。

The cell membrane oxidation of fruit could be depressed with chitosan coating. The stability of cell membrane of strawberry and huanghua pear were enhanced and the content of MDA reduced remarkably after coating.

采后黄花梨果肉MDA含量呈现峰谷变化，而壳聚糖涂膜处理使其MDA积累峰值显著降低，其中套袋梨降低23.1%和32.6%，不套袋梨降低11.40%和12.68%，两者均达到显著水平（P＜0.01）。
