the increase of citrulline was interpreted to be produced by decreased conversion of citrulline to argininosuccinate due to a lack of aspartate because of inhibition of aspartate aminotransferase by the drug and increased formation of citrulline due to increases of glutamate and ammonia , which further induced the increase of n-acetylglutamate , because of inhibition of aminotransferase as well as stimulation of amino acid degradation by glucocorticoids .
