Results Compared with low-salt diet control group, the renal changes in CsA-L group were not obvious at the 2nd weeks, the urine volume and the level of BUN were remarkably increased in CsA-H group. At the 4th weeks, the urine volume was decreased; the levels of Crea and BUN were significantly increased and showed a significant positive correlation with the blood CsA concentration. Morphologic changes consisted of vacuolization of renal tubular cells, hyalinization of small arterioles and the light renal interstitial fibrosis.

结果 与低盐对照组相比，药后第2周CsA-L组各指标无明显变化，CsA-H组尿量增多，尿蛋白降低，尿素氮升高；药后第4周时，尿量呈减少趋势，肌酐和BUN明显升高，且与CsA血药浓度呈显著正相关，病理表现为肾小管细胞空泡变性及小动脉和肾间质病变，CsA-H组各种变化较CsA-L组更为明显。
