The experiments were done on mice divided into three experimental and control groups. The test group of mice received morphine, ethanol or morphine plus ethanol. The control group received only 0.85% NaCl. tRNA was obtained by phenol extraction from the livers of tested and control mice. The quantity of often radioactive amino acids bound to tRNA was measured. Morphine and ethanol changed the quantity of amino acids bound to tRNA. It was different for an individual amino acid and for tested tRNAs.
