Mercuric chloride stress on serum transaminase activity in Notopterus notopterus.

Mercuric intoxication at sublethal levels (1/5, 1/10, 1/15, 1/20 or 1/25 fractions of 96 h LC50) produced alterations in the activity of serum glutamic oxalacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) of Notopterus notopterus. The difference between control and treated fish was found to be significant at P less than 0.05, P less than 0.01 and P less than 0.001 levels. Maximum (81.75%) significant (P less than 0.001) effect was observed in SGOT: maximum (69.23%) significant (P less than 0.001) effect was observed in SGPT in fish exposed for 60 days.
