钠排泄分数

结论：早产儿胎龄越小，肾小球滤过率越低，钠排泄分数越高。

Conclusion : The smaller of gestational age in preterm infants , the lower of glomerular filtration rate and the higher FENa .

4周时，哇巴因组的钠排泄分数显著低于对照组（P<0.05），表明哇巴因组近端小管钠重吸收的增加，同时伴随着钠排泄的减少。

FENa was significantly lower at week 4 in ouabain group than in the control group ( P < 0.05 ), but this difference was not significant in weeks 2 and 6 ( P > 0.05 ) .

结果表明，异博定能增加肌酐清除率，降低血尿素氮和滤过钠排泄分数，可以保护肾小球、肾小管的细胞结构，有防治急性肾功能衰竭的作用。

The results showed that verapamil increased creatinine clearance rate ( Ccr ), reduced blood urine nitrogen ( BUN ) and filtration excretion of sodium ( FENa ), and protected the kidneys from acute renal failure in rabbits .

HC组的内生肌酐清除率显著低于H组，HC组的血清肌酐、钠钾排泄分数显著高于其它三组。

The values of serum creatinine , fractional excretion of sodium and potassium in group HC were significantly higher than those in the other groups .

同时检测血钠、尿钠、血肌酐、尿肌酐、血尿素氮；计算钠排泄分数（FENa）、肌酐清除率（Ccr）、肾衰指数（REI）。

Blood and urine sodium , blood and urine creatine , blood BUN , FENa , Ccr , REI were also detected .
