摘　　要：运用硫辛酸脱氢酶(NADPH-d)组织化学方法研究了两种纽形动物一氧化氮合酶的分布情况,实验结果表明,短无头沟纽虫(Baseodiscuscurtus)的阳性反应位于体表上皮细胞和神经系统的脑神经节和侧神经索中,纵沟纽虫(Lineussp.)的阳性反应只位于体表上皮细胞中.比较了纽形动物与扁形动物和环节动物一氧化氮合酶组织化学定位的异同.The distribution of nitric oxide synthase (NOS) positive cells and fibers in two nemerteans (Baseodiscus curtus, Lineus sp) was studied with NADPHdisphorase histochemical methodThe result shows that the NOS positive reaction is located in epithelial cell, brain and lateral nerve cord of Baseodiscus curtus, and epithelial cell of Lineus sp only This result is compared with the similar studies in platyhelminth and annelid
