Abstract

|
Effects of insecticide carbofuran and Phenobarbital sodium(PB) or 3-methylcholanthrene(3-MC) on activities of several enzymes in israeli carps were investigated. Survival number of Israeli carp was the same as that of control when PB and 3-MC only was treated, individually and that was low compared to control when carbofuran only was treated. But survival rate of Israeli carp was high compared to individual treatment of carbofuran when combination treatment of carbofuran and PB or 3-MC was carried out. These results indicate that PB and 3-MC can intervene to detoxify carbofuran exposed to israeli carp. In in vivo test for the effect of this chemicals on activity of enzyme in israeli carp, activities of acetylcholinesterase(AChE) and glutathione S-transferase(GST) were inhibited in carbofuran treatment, but did not in combination treatment of carbofuran and P3 or 3-MC. Activities of UDP-glucuronosyltransferase (UDPGT) and cytochrome P-450-dependent monooxygenase increased in individual or combined treatments of carbofuran and PB or 3-MC. These results suggest that a simultaneous application of carbofuran and PB or 3-MC is critical for the enhancement of activity of AChE, GST, UDPGT and monooxygenase and the protection of Israeli carp from carbofuran toxicity.
