Abstract:

Cadmium has been found to produce wide ranges of biochemical and physiological dysfunctions in humans and animals. In the present study, toxic effects of Cadmium nanoparticle (CdNP) in the vasdeference of mud crab Scylla olivacea was evaluated. Crabs were exposed to different concentrations of CdNP (from 0 to 120 ppm/kg) for 8 days. The toxicity study revealed that LD50 value was found to be 40 ppm/kg of crab on day 6. CdNP (20ppm ppm/kg) induced abnormal structural changes in the vasdeference such as disintegration of principle cells, vacuolar degeneration, distortion of stereocilia and seminiferous epithelia. In addition, CdNP also induced antioxidant enzymes such as Catalase (CAT), Glutathione Peroxidase (GPx) and Superoxide dismutase (SOD). CdNP also modulates the activity of mitochondrial enzymes such as Lactate dehydrogenase (LDH), Succinate dehydrogenase (SDH) and Malate dehydrogenase (MDH).


Keywords: Cadmium nanoparticle, S. olivaceae, Vasdeference, antioxidant enzymes.
