低氧胁迫对菲律宾蛤仔抗氧化酶的影响
Response of the Manila clam antioxidant enzyme to hypoxia stress under experimental conditions
摘要
Abstract
In order to study the effect of different hypoxia levels on the Manila clam Ruditapes philippinarum,we set the dissolved oxygen (DO: 0.5 mg/L) and (DO: 2.0 mg/L) under laboratory hypoxia conditions, and natural seawater (DO: 7.0 mg/L) as the control group. The responses of the R. philippinarum antioxidant enzyme to hy-poxia stress under experimental conditions were investigated in the present study. The results showed that the ac-tivities of lactate dehydrogenase (LDH) and succinate dehydrogenase (SDH) decreased gradually in the longer hy-poxia stress conditions, but the activity of alkaline phosphatase (AKP) increased gradually. The activity of the same enzyme in the control group was higher than in the hypoxia treatment group. There were lower levels of dissolved oxygen and higher mortality rates in R.philippinarum.The results provide a biological foundation for the physio-logical ecology of the R.philippinarum under low oxygen environment.关键词
