The use of glyphosate as a herbicide in agriculture can lead to the presence of its residues and metabolites (aminomethylphosphonic acid) in food for human consumption and pose a threat to health. The effect of these herbicides on the fish organism at the biochemical level has been insufficiently studied. We studied changes in the content of adenine nucleotides, enzyme activity, quantitative indexes of energy metabolism substrates in carp under the action of glyphosate. It has been found that proteins are the major ener­gy substrate under the influence of glyphosate in the liver, brain, white muscle of carp yearlings. Glyphosphate  decreases energy metabolism in the brain of carp and increases it in the white muscles. The growth of activity of catabolic enzymes in the liver under the influence of glyphosate can be attributed to the adaptive remodelling of metabolic pathways for homeostasis and enantiostasis in response to herbicides

Cesium is lately accumulated actively in the environment, but its influence on human and ani­mal organism is the least studied among heavy metals. It is shown that the action of cesium chloride in rats caused significant changes in blood chemistry, which are characterized by a decrease of total protein content, pH, an increase in the level of urea, creatinine, glucose and total hemoglobin. The results showed that potassium content in all the studied organs and tissues of poisoned rats decreases under the action of cesium chloride. Histological examination of the heart tissue in rats poisoned with cesium chloride indicates the onset of pathology of cardiovascular system. It was found out that use of the drug “Asparkam” reduces the negative effect of cesium chloride on the body of rats.
