富硒黑木耳硒多糖对鲤鱼镉暴露的减毒作用
Detoxification Effect of Selenium-Enriched Auricularia auricula Selenium-Polysaccharide on Cadmium Exposure of Common Carp
摘要
Abstract
To investigate the detoxification effect of selenium-enriched Auricularia auricula selenium-polysaccharides on cadmium-exposed carp,540 carps were divided into six groups:control group,selenium-enriched Auricularia auricula selenium-polysaccharide group,non-selenium-enriched Auricularia auricula polysaccharide group,cadmium-exposed group,cadmium-exposed selenium-enriched Auricularia auricula selenium-polysaccharide group,and cadmium-exposed non-selenium-enriched Auricularia auricula polysaccharide group.The cadmium exposure dose was 1 mg/L,and polysaccharides and selenium-enriched polysaccharides were added to the basic diet.The polysaccharide group received 3 g/kg of polysaccharides,and the selenium-enriched polysaccharide group received 3 g/kg of polysaccharides and 8.1 μg/kg of selenium.The experimental period was 60 days.At days 30 and 60 of the experiment,samples of spleen,liver,gills,kidneys,brain,muscles,and blood were collected.Cadmium concentration in each sample,red blood cell count,white blood cell count,and hemoglobin content in the blood were measured.Acetylcholinesterase,Na+/K+-ATPase,dopamine,and serotonin levels in the brain were measured.At day 60 of the experiment,body weight and liver pancreas weight were measured,and weight gain,growth rate,hepatopancreatic index,and feed conversion rate were calculated.The results showed that compared with the cadmium-exposed group,selenium-enriched Auricularia auricula selenium-polysaccharides or non-selenium-enriched Auricularia auricula polysaccharides significantly reduced cadmium concentrations in tissues and blood(P＜0.05),increased hemoglobin content(P＜0.05),decreased white blood cell count(P＜0.05),increased acetylcholinesterase,dopamine,Na+/K+-ATPase,and serotonin levels in the brain(P＜0.05).Moreover,the selenium-enriched polysaccharide showed better effects than the polysaccharide.These results indicate that selenium-enriched Auricularia auricula selenium-polysaccharides have a certain alleviating effect on the toxicity of cadmium exposure in carp.关键词
