摘要
为揭示方斑东风螺(Babylonia areolata)在低pH和高pH胁迫时的急性毒性和生理变化,以pH=8.0为对照组,pH=5.0、6.0、7.0和9.0为试验组,测定方斑东风螺体内4种免疫酶:谷胱甘肽过氧化物酶(GSH-PX)、过氧化氢酶(CAT)、过氧化物酶(POD)和酸性磷酸酶(ACP)活性。结果显示:不同时间pH胁迫对免疫酶活性有显著影响(P<0.05),而不同pH胁迫对免疫酶的活力没有显著影响(P>0.05);方斑东风螺经过pH急性胁迫后,在低pH和高pH的水体养殖6 h后都出现了活力下降、爬壁缓慢,而在48 h后开始出现死亡;各试验组GSH-PX活性均呈现“抑制-诱导”的变化趋势;随着时间的不断延长,各pH处理组CAT活力均呈现“诱导-抑制-诱导”的变化趋势;POD活性总体表现出了“诱导-抑制”的趋势;低pH处理组(pH=5.0、6.0)ACP活性表现出“诱导-抑制”的趋势。该研究对于方斑东风螺的养殖具有参考意义,同时丰富贝类免疫系统方面的基础资料。
To reveal the acute toxicity and physiological changes of Babylonia areolata in response to low pH and high pH stress,the pH=8.0 control group and pH=5.0,6.0,7.0,and 9.0 were used as the experimental group to investigate the activities of four immune enzymes glutathione peroxidase(GSH-PX),catalase(CAT),peroxidase(POD)and acid phosphatase(ACP)in the body of the Babylonia areolata.The results of the experiment show that pH stress has a significant effect on immune enzyme activity at different times(P<0.05),while different pH stresses have no significant effect on immune enzyme activity(P>0.05).After pH acute stress,1)after 6h of low pH and high pH water culture,there is a decrease in vitality and slow climbing,and death begins to appear after 48h;2)The activity of GSH-PX in each experimental group shows a trend of"inhibition-induction";3)with the continuous extension of time,the CAT activity of each pH treatment group shows a trend of"induction-inhibition-induction";4)the POD activity generally show a trend of"induction-inhibition";5)the ACP activity of the low pH treatment group(pH=5.0,6.0)show a trend of"induction-inhibition".This study has practical significance for the cultivation of Babylonia areolata,and also enriches the basic data on the immune performance of other shellfish.
