Abstract
A family of hemoproteins known as cytochrome P-450, which is known to perform a major role in the metabolism of various agents, has been investigated in fish as a criterion for monitoring water pollution. This enzyme is well known to be induced by various chemicals in fish as well as mammals. However, very little information is available concerning the effects of environmental pollutants on the activity of heme oxygenase, the first and rate-limiting enzyme for heme degradation. To investigate the nature of heme oxygenase is of particular interest in that if heme oxygenase activity is altered by contaminants, that may contribute to the effect on physiological changes of heme and hemoprotein P-450. In this study the authors investigated the effects of heavy metals, pesticides and surfactants on the MBP and the heme oxygenase in the hepatopancreas and kidney of a fresh water red carp (Cyprinus carpio Linne).
