CHANGES IN CERTAIN ACUTE PHASE PROTEINS OF COMMON CARP (Cyprinus carpio) EXPOSED TO ORGANOPHOSPHATE INSECTICIDES

The acute phase response (APR) is a nonspecific reaction of fish to disturbances in homeostasis. The aim of present study was to investigate quantitative changes that occur in the concentration of acute phase proteins (APPs) in the blood of commercial size common carp ( Cyprinus carpio L. ) exposed to organophosphate insecticides within the month of April during ameliorative activities. Parameters examined were fibrinogen (Fib), ceruloplasmin (Cp) as a positive APPs and albumin (Alb) as a negative APP. Histological sections of the hepatopancreas and kidneys from 25 fish have been examined. The hepatopancreas was chosen for this investigation as it is the primary site of acute phase protein synthesis. APP parameters plasma fibrinogen ( P <0.05) registered a significantly increased and albumin ( P <0.05) exhibited statistically declined in treated group. Based on the data acquired in this study, it was concluded that, the carp do not exhibit a strong APP synthesis during the early stages of an APR after spraying with organophosphate insecticides. The results from this study show that t he concentrations of fibrinogen are not significantly increase as well as the levels of ceruloplasmin remained unchanged.
