Biochemical and subcellular changes in carp exposed to the organophosphorus methidathion and the pyrethroid deltamethrin

Effect of polychlorinated biphenyls (Delor 103) on haematological and enzyme parameters of the rainbow trout Oncorhynchus mykiss

“…In this context, the acceleration of haematopoiesis can be simply explained as a stress response by releasing stored cells from the spleen. It was an interesting finding that there was no hyperglycaemia, which is otherwise a frequent response of fish to the action of a number of pollutants (Srivastava 1981, Singh & Srivastava 1982, Natarajan 1989, Gill et al 1990, Balint et al 1995, Sancho et al 1997, Lusková et al 2002.…”

The Effects of Pyrethroid and Triazine Pesticides on Fish Physiology

“…Jee et al (2005) found an increase in levels of serum glutamic-acid-oxylacetic-acid-transaminase, glutamic-acid-pyruvic-acid-transaminase, GLU, and ALP and a decrease in the concentration of plasma TP, ALB, cholesterol, and lysozyme in Korean rockfish (Sebastes www.intechopen.com schlegeli) exposed to cypermethrin. Balint et al (1995) observed an increase of GLU in common carp (Cyprinus carpio) after exposure to deltamethrin. Atamanalp et al (2002) found changes in the concentration of Ca 2+ and phosphorus in rainbow trout following cypermethrin exposure.…”

Biochemical biomarkers of exposure to deltamethrin in freshwater fish, Ancistrus multispinis

“…However, its effects on nervous, respiratory, and hematological systems in fishes have been reported (Ural andSağlam, 2005, Pimpão et al, 2007). Bálint et al (1995) observed 20% decrease in acetylcholinesterase activity of brain, heart, blood, liver and skeletal muscle of carp after the 3 days exposure to deltamethrin. In rats, the main reaction involved in the metabolism of deltamethrin is ester cleavage, by CYP450 and carboxyesterase action.…”
