Due to higher content of protein in chondroitinsulfate wastewater and low measured value of ammonia nitrogen, organic nitrogen was neglected in designing wastewater treatment process.
硫酸软骨素废水中蛋白质含量虽然较高，但氨氮测定值较低，导致有机氮问题在设计时容易被忽视。

Objective:To investigate the effects of chondroitinase ABC on chondroitinsulfate proteoglycans(CSPGs) and growth associated protein-43(GAP-43)after spinal cord injury in rats.
METHODS:The bilayer minipellet was prepared and shaped by pressurizing gel with the collagen protein as coating material and the sodium chondroitinsulfate as releasing moderator;
