Description:
In this study, the effect of MTBE on liver, gill and kidney tissues, as well as comet assay and oxidative enzymes catalase and superoxide dismutase in (Rutilus caspicus), have been investigated in laboratory conditions. For this purpose, the substrate concentrations of 50, 100.150 mg / L MTBE on changes in liver, gill and kidney tissues, as well as the rate of destruction of blood cell DNA and, finally, the effect of this contaminant on the activity level of oxidative enzymes catalase And superoxide dismutase the blood serum was studied based on sampling done on days 7, 14, 21 days after exposure to MTBE. To quantify the changes, Casp 1.2.3 bar1 software was used. Data analysis using SPSS software (Ver.21) was used for plotting the graphs from Excel 2013 software. According to the results between the concentrations of MTBE There is a positive and significant relationship between the SOD and CAT enzymes (P〈0/01). In this way, with increasing MTBE, the activity of the SOD and CAT enzymes increases compared to the control group. The results of histological studies showed that the tissues exposed to MTBE were damaged and damaged, as well as the DNA of the cells. The blood was destroyed and damaged. The severity of injuries was higher at higher concentrations and over time.
