Isolated and combined effects of pesticides on serum transaminases in Mystus vittatus (African catfish).

Alterations in serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) levels of Mystus vittatus (African catfish) after exposure to subacute concentrations of thiotox (T), dichlorvos (D), and carbofuran (C) and their combinations C/T (antagonistic), T/D (additive) and (T + D)/C (synergistic) for a period of 30 days have been investigated. Alterations were more evident in SGOT than in SGPT. Maximum (92.5%) elevation was observed with SGOT at the highest concentration of (T + D)/C combination and the lowest (14.76%) at the lowest concentration of T/D combination. Significant (P less than 0.05) stimulation was observed except at the lowest concentration after all treatments.
