EFFECT OF SUB-LETHAL CONCENTRATION OF DIAZINON ON SOME BIOCHEMICAL PARAMETERS OF BLOOD, KIDNEY TISSUE AND MUSCLES OF PERSIAN STURGEON FINGERLINGS ACIPENSER PERSICUS
Abstract
This study was carried out with the aim of detecting sub-lethal effects of diazinon on some biochemical parameters of blood, kidney and muscle tissues of Persian sturgeon fingerlings. A total of 120 fingerlings were exposed to different concentrations of diazinon. Clinical responses and also blood indices were studied after 24 and 92 hours. Circular swimming, fast motion of gills and body imbalance were observed at all the experiments, but muscle collapse and changes in gill and abdomen color were observed in fish exposed to higher concentrations of diazinon. Cortisol hormone level depended significantly on the concentration and time of exposure to the toxicant. Glucose level was increased significantly after 96 hours. Histopathological effects of diazinon on kidney and muscle tissues of fingerlings were studied using a light microscope. Diazinon toxin caused degeneration of urinal tract epithelium cells, petechiae, hemorrhage and hemosiderin sediment, existence of eosynophile in urinal tracts, hyperplasia and enlargement of Bowman’s capsule in the kidney tissue. In the muscle structure of treated fishes, some disasters such as edema, muscle necrosis and hemosydrosis were observed.
