A single administration to rats of cyanamide (60 mg/kg, for 1 hour) was found to decrease the contents of cysteate, serine, glutamate, glycine, alanine, valine, methionine, isoleucine, tyrosine, ethanolamine, ornithine and histidine that may be considered as a manifestation on the drug hepatotoxicity. The activities of transaminases, glutamate dehydrogenase, pyruvate dehydrogenase remained unchanged. Cyanamide effects were considerably abolished by the supplementary ethanol administration (0.5 g/kg). Cyanamide failed to affect vitamin-dependent enzymes reflecting thiamine pyrophosphate, pyridoxal phosphate and flavine adenine dinucleotide status of the rat organism. |
