ABSTRACT
This study was carried out to evaluate spontaneous renal regeneration after stopping colistin methanesulfonate (CMS), which induces tubular damage, and the curative effect of Vitamin E (vit E) in rats. Animals were given the following sterile saline (n = 6), 300,000 IU/kg/ day of CMS (n = 24), or 450,000 IU/kg/day of CMS (n = 24) for seven days. Each CMS group was subdivided into four subgroups (n = 6) and sacrificed as follows (i) 12 h after stopping CMS, (ii) two weeks after stopping CMS, (iii) two weeks after stopping treatment with vit E, and (iv) two weeks after stopping treatment with olive oil. Subsequently, plasma creatinine (pCr), urine N-acetyl-b-D-glucosaminidase (NAG), renal tissue level of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione reductase (GSH), and renal histology were tested. CMS-induced tubular damage increased the NAG and MDA levels and decreased the SOD and GSH activities. After two weeks of stopping CMS, there was no significant renal recovery. However, treatment with vit E improved tubular regeneration and reduced the biochemical impairments. Two weeks might not be long enough for significant spontaneous renal regeneration. Improvement of renal parameters by vit E could be explained by the reduction of oxidative stress damage.
