摘要:

本文概述了硫化物的生理毒性, 包括对生物体的有氧呼吸毒性, 神经毒性, 线粒体毒性, 核酸和蛋白质毒性。总结了单环刺螠在硫化物胁迫下存在的应对机制, 包括体壁分泌粘液, 细胞凋亡过程中某些酶活性的升高和凋亡通路的放大; 体内氧化酶活性的改变; 体腔液某些成分含量及细胞器结构的变化, 线粒体内相关酶系的氧化以及RNA、DNA结构和含量的变化等。

关键词: 单环刺螠硫化物酶结构耐受

The research progress on the tolerating mechanism for sulfide in Urechis unicinctus

LIU Feng,LI Guang-ya,ZHAO Yu-han,SUN Tao,JI Yuan,YU Hai-rui

Abstract:

The paper summarizes an overview of sulphide physiotoxicity, including the toxicity of aerobic respiratory, neurotoxicity, mitochondrial, nucleic acid and protein in organisms, and the coping mechanisms of Urechis unicinctus under sulphide stress including mucous secreted from the body wall; enzymes activity and apoptotic pathways are amplified during cell apoptosis; oxidase activity, components, and the structure of organelles in the body are changed; some enzymes in mitochondria are oxidized; and the structure of RNA and DNA are changed.

Key words: Urechis unicinctus sulfide enzyme texture tolerance
