Peroxynitrite induced decrease in Na+, K+-ATPase activity is restored by taurine

Table 2 Effects of 200 μmol/L decomposed ONOO^- and ONOO^- with and without taurine on liver plasma membrane Na⁺, K⁺-ATPase activity (values are mean±SD, n = 10).

Groups	Na+,K+-ATPase activity (nmol Pi/mg Pr/min)
Decomposed ONOO- (200 mmol/L)	261.86±38.32a
Decomposed ONOO- (200 mmol/L) +taurine (1 mmol/L)	460.24±51.28a
Decomposed ONOO- (200 mmol/L) +taurine (2 mmol/L)	452.07±50.92a
Decomposed ONOO- (200 mmol/L) +taurine (5 mmol/L)	435.61±71.44a
ONOO- (200 mmol/L)	62.36±18.77a
ONOO- (200 mmol/L)+taurine (1 mmol/L)	115.37±27.19a
ONOO- (200 mmol/L)+taurine (2 mmol/L)	114.34±27.34a
ONOO- (200 mmol/L)+taurine (5 mmol/L)	113.86±16.32a
