Özet

The effect of taurine on the plasma levels of Ll-arginine, asymmetrical dimethylarginine (ADMA) and L-arginine/ADMA ratio and nitric oxide was investigated in experimental endotoxemia. L-arginine and ADMA levels were quantified by high performance liquid chromatography with fluorescence detector. Nitric oxide level was measured with spectrophotometric method. All experiments were performed with four groups (control, taurine, endotoxemia, taurine plus endotoxin) of 10 guinea pigs. After the endotoxin was administrated (4 mg/kg) ADMA level increased, nitric oxide level did not change but L-arginine level and L-arginine/ADMA ratio decreased. When taurine was administrated (300 mg/kg) no effect on ADMA and nitric oxide levels was observed compared to the endotoxemia group. But it was increased the L-arginine/ADMA ratio. Taurine may offer an advantage in because of it increases the reduced L-arginine/ADMA ratio.
