Abstract:
:The studies on the effects of phenol (P), 2,4-dinitrophenol (DNP), pentachlorophenol (PCP) individually and in three combinations, viz., (PCP + DNP)/P (highly antagonistic), (DNP + P)/PCP (additive), and (P + DNP)/PCP (highly synergistic), at three sublethal levels (1/10, 1/15, and 1/20 of the 96-hr LC50) on the activity of hydrolytic enzymes (acid, alkaline, and glucose-6-phosphatases and 5-nucleotidase) in the brain and kidney of a fresh-water teleost, Notopterus notopterus revealed inhibition of enzyme activity after 15 and 30 days of exposure. Maximum inhibition (-89.32%) was observed in acid phosphatase activity in brain at 1/10 concentration of (P + DNP)/PCP combination after 30 days, but minimum (-3.64%) in activity of glucose-6-phosphatase in kidney at 1/20 of (PCP + DNP)/P combination after 15 days of exposure. However, biphasic effects of P, DNP, and (PCP + DNP)/P combination were observed in kidney, i.e., inhibition of enzymes activity at higher concentrations and stimulation at lower concentrations after both time intervals.
