| Abstract | ||
| The effect of three concentrations (4,12 and 18 mg/L) of the organophosphorus fungicide; pyrazophos on the activity of certain enzymes; acetylcholinesterase (AChE) and buterylcholinesterase (BuChE) in brain, some liver detoxifying enzymes transaminase (GOT) and glutamic pyruvic transaminase (GPT), acid phosphatase (ACP), glutathione-S-transferase (GST) and catalase (Case) in liver and lipid peroxidation of common carp in different organs (liver, kidney, gill and muscle) after 24 hours of the treatment were investigated. The data showed a significant inhibition of the AChE and BuChE activities in a concentration dependent manner. Activities of GOT and GPT were significantly decreased with all tested concentrations, with the exception of a significant induction which was found in fish exposed to the lowest concentration of 4 mg / L. No significant changes on AcP and GST activities were noted. On the other hand, the lowest concentration of pyrazophos caused a significant reduction in catalase activity. Also, the data illustrated that lipid peroxidation was significantly increased in liver and gill with all concentrations when compared with the control. | ||
