Loteste A, Cazenave J, Parma de Croux MJ: Recovery of plasmatic cholinesterase activity in a neotropical fish Prochilodus lineatus (Pisces, Curimatidae) exposed to organophosphorous pesticides. J Environ Biol. 2002 Jul;23(3):225-9.
The objective was to determine the plasmatic enzyme cholinesterase recovery, after being inhibited by an organophosphorous in juveniles of Prochilodus lineatus. Fish were exposed 12 h to a sublethal concentration of 1 mg/l of monocrotophos, and immediately placing in clean water during 12, 24, 48 and 96 h to detoxification. After this period, blood was extracted and plasma were used for the quantification of cholinesterase. The results showed a enzymatic inhibition of 91.9%, 55.1%, 50.4% and 33.4% with 12, 24, 48 and 96 h of recovery, respectively. The enzymatic activity spreads to be normalized with the course of hours and the degree of inhibition obtained initially was very high and sustained in the first 48 h. |
