Action of lead acetate and potassium dichromate on lysozyme activity in cyprinus carpio l.

S. I. Danyliv, N. M. Kepeshchuk, M. A. Mazepa

It is explored activity of lysozyme at mucus and blood serum of the carp Cyprinus carpio L. in a norm and at presence of lead and chromium ions in a water environment. It is set that the ions of the explored metals caused the similar effects in lysozyme activity. The lead ions in concentration 0,2 and 0,5 mg/l draws increase of this enzyme activity at mucus in 3,1 and 3,7 times accordingly, and also decrease of this index in the blood serum 3,8 times. The presence of chromium ions in an environment cause increase of this index in mucus in 3,7 and 10 times (1 and 2,5 mg Сr6+/l) and decrease of it in serum at the concentration in 1 mg/l. It is evidently that the ions of the explored metals predetermine growth of lysozyme activity at mucus and decline of this index in the blood serum of Cyprinus carpio L.
