چکیده مقاله
Silver nanoparticles AgNP are one of the most important nanomaterials that have widespread applications in different industries, which in turn extensive use of it increases the potential of release and accumulation in aquatic ecosystem Due to the importance of evaluating the toxicity of metal nanoparticles in valuable aquatic species, the present study aimed to investigate the sub acute effects of silver nanoparticles on immune responses of Mugil cephalus In present study, at first the LC50 test of silver nanoparticles were studied based on the standard OECD 1998 method within 96 hours Finally, after determining the 50% lethal concentration LC50 , the fish were exposed to sublethal silver nanoparticles concentrations equivalent to 25, 50 and 75% LC50 of AgNPs for 14 days To measure the activity of lysozyme, total serum protein and IgM fish were sampled for blood collection on day 14 LC50 value of AgNP in Mugil cephalus were determined to be 4 37 mg/L The results showed that lysozyme and serum complement activity of fish exposed to 75% LC50 of AgNPs were significantly decreased compared with control group p>0 05 Total protein of serum and total immunoglobulin in the samples, although on different treatments had decreased or increased volatility, but this increase or decrease compared with the control group was not statistically significant p>0 05 Overall, the results showed that exposure to 75% LC50 of AgNPs induce the immune response of Mugil cephalus
