Тhe effect of glyphosate-resistant genetically modified soybean and herbicide “Roundup” on the enzymatic activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and γ-glutamyltransferase (GGT), and on the content of middle mass molecules in rat serum has been investigated. The studies were made on the Wistar rats divided into five groups: 1st group — intact; 2nd group — 25% of rat’s ration was replaced by traditional soybean; 3rd group — the rats received feed containing genetically modified soybean not treated with the herbicide “Roundup”; 4th group — the rats received feed containing genetically modified soybean treated with the herbicide; 5th group — the rats received the herbicide “Roundup” with drinking water. After 42 days females of all groups were mated and continued to receive the same diet and herbicide with drinking water. In 22–24 days the next generation of rats was born. In the first and second generation of rats fed with the herbicide “Roundup” and transgenic soybean treated with this herbicide, the hyperenzymemia of ALT, AST and GGT in compared with control group was observed. At the same time, De Ritis Ratio was reduced to values of 0.8 and 0.7 for the rats fed with soybean “Roundup Ready” and herbicide, respectively. It is shown that the level of middle mass molecules in blood serum of the first rat generation increases in 1.5 and 1.6 times in cases of feeding rats with genetically modified soybean treated with herbicide and herbicide only; the increase in the content of middle mass molecules is observed in the second generation too. The increase of middle mass molecules content in blood serum indicates a syndrome of endogenous intoxication.
