“…The lowest activity was observed in liver. This study confirms the different distribution and localization of AChE in fish organs (Nemcsók et al., 1990; Szegletes et al., 1995). Information on normal background levels in different fish tissues may be useful in deciding the organ to monitor (Bocquené et al., 1990).…”

Acetylcholinesterase (AChE) activity is a well-known biomarker for exposure to organophosphate or carbamate compounds in aquatic organisms. However, the effect of dibutyl phthalate (DBP) and di-ethylhexyl phthalate (DEHP), widely used as a plasticizer, on the change of AChE activity is not yet known. Bagrid catfish Pseudobagrus fulvidraco were administrated with 100, 500 and 1000 mg kg )1 diet of DBP or DEHP and the effects on AChE activity were assessed in the liver, gill, kidney, heart, brain, muscle and eye of the exposed fish. All tissues contained different background AChE activity in non-treated bagrid catfish: the highest was observed in the brain, followed by muscle, heart, and kidney. The enzyme activities in various tissues were significantly inhibited after exposure to DBP or DEHP in a concentration-dependent manner, especially in brain and muscle. A similar, but less pronounced, inhibition was also observed in liver and kidney when exposed to DBP and DEHP. Although AChE activity in gill and heart was also affected by DBP and DEHP, the decrease in these organs was least marked in these organs. Exposure to 1000 mg kg )1 led to mortalities of 8.0% with DBH and 14% with DEHP; both seemed to be ascribable to phthalate toxicity. This study is the first report that the measurement of AChE activity in bagrid catfish is a valuable biomarker of DBP and DEHP exposure. This biomarker could be incorporated into a battery of biomarkers to strengthen the confidence with which ecotoxicologists can assess the impact of phthalate ester pollution in the aquatic environment.

“…The intensity of AChE inhibition might also be correlated with the degree of accumulation/interaction of pyrethroids and/ or their metabolites in different organs (World Health Organization EHC 1989, 1990). The differential distribution of different molecular forms of AChE as well as their mode of interaction with pyrethroids might be another possible reason for observed patterns of AChE inhibition in different organs (Szegletes et al 1995). The differential degree of nerve innervations in these organs might be one of the reasons for organ specific differences (Almeida, Aguiar, and Moraes 2005).…”

In this study was evaluated the hematological response of ornamental Amazon plecos Cochliodon sp. (L145) and Hypostomus sp. (L28) submitted to transportation conditions. The erythrogram, leukogram, thrombogram, glucose and total plasma proteins (PPT) were determined at 0, 6, 24, 48 and 72 hours after 3-hours simulated transportation. For basal hematological profile, the blood was collected immediately to allow comparisons after the transport stress. Cochliodon sp. showed reduction in total erythrocyte after 6 and 24 hours of post-transport, and increase after 6 hours. Hypoglycemia were observed at 6 hours post-transport for Hypostomus sp. Thus, the Hypostomus sp. showed higher resistance compared to Cochliodon sp. when to the transport stress.
