The behaviour of aspartate aminotransferase (AspAT) an alanine aminotransferase (AIAT) in the whole homogenate and subcellular liver fractions of guinea pigs exposed to combustion exhaust gases and the neutralization products of these gases is presented in this paper. In the liver of animals exposed to the chronic action of combustion exhaust gases a decrease of both enzyme activities in the whole homogenate as well as in the subcellular fractions could be noted. Statistically significant changes are shown by AspAT.

The paper presents the behaviour of DNA, RNA and soluble proteins in whole homogenate as well as the nuclear, mitochondrial and postmitochondrial liver fractions in guinea pigs exposed to combustion exhaust gases and the products of their reaction with ammonia. A decrease of RNA level was found in the liver of animals exposed to combustion exhaust gases together with a decrease of soluble proteins in all the studied fractions. On the other hand, in the group of animals subjected to the action of neutralization products of combustion gases by ammonia, the studied components were increased.
