title: Impact of cypermethrin on Na(+)-K (+), Ca (2+) and Mg (2+) ATPases in Indian major carp, Cirrhinus mrigala (Hamilton).
abstract: Activities of ATPase in different organs of Cirrhinus mrigala exposed to cypermethrin with lethal (5.13 microg/L) and sublethal (1.02 microg/L) concentration was investigated. Decrease of Na(+)-K(+)-ATPase activity was observed in gills, liver and muscle to about 60.22%, 22.13% and 48.89% respectively, by lethal concentration. Whereas in sublethal concentration activity was increased to about 7.84%, 10.70% and 5.96%. Similarly, in case of Mg(2+)-ATPases activity as 57.61%, 48.82% and 28.59% for lethal and for sublethal it was 10.15%, 4.64% and 11.92%. Ca(2+)-ATPase activity was observed to be 55.24%, 41.66% and 47.66% by lethal and for sublethal it was 8.02%, 24.89% and 6.47%.
