摘要
The changes of plasma PTH, 1,25（OH）D, serum calcium, phosphorus and AKP were observed in 55 uremic patients with renal osteodystrophy. The results showed that: in all types of renal osteodystrophy, plasma PTH were markedly higher than normal （P<0.001）, while plasma 1,25（OHH）Dand serum calcium were lower than normal （P<0.001）. In low bone-turnover uremic osteodystrophy （LTO）, plasma phosphorus was markedly lower than that of high bone-turnover uremic osteodystrophy （HTO） and mixe d uremic osteodystrophy （MO） （P<0.05）, and plasma 1,25（OH）Dwas significantly lower than that of HTO （P<0.05）. In HTO and MO, serum phosphorus was much higher than mormal （P<0.001）. Plasma PTH had a negative linear correlation with plasma 1,25（OH）D（P<0.05）, a positive linear correlation with serum AKP （P<0.05）, but no linear correlation with the duration of hemodialysis, serum calcium, serum aluminum and bone aluminum content. Plasma 1.25（OH）Dhad no linear correlation with the duration of hemodialysis, seru
