Nephroprotective Effect Of Nifedipine Against Lead Toxicity In Mice - 2017. - 52P.;
This study was designed to evaluate the nephroprotective effect of nifedipine against lead toxicity in mice. Exposure to lead can induce kidney damage, which is related to induction of oxidative damage and disturbance of intracellular calcium homeostasis.
Twenty mice, weighing 20.0 ±2.0 g were selected for the experiment. Twenty mice were divided randomly into four groups having five mice in every group as follows: control, lead, low-dose nifedipine and high-dose nifedipine. Mice of the low- dose and high-dose nifedipine groups were given nifedipine perorally at 10 and 20 mg/Kg/day, respectively. While the mice of the lead and control groups were administrated perorally with isovolumic saline. The mice of the low-dose nifedipine, high-dose nifedipine and lead groups were injected intraperitoneally with lead acetate 40 mg/Kg/day after treatment with nifedipine. Mice in the control group were injected intraperitoneally with isovolumic saline. The whole treatment period remains for ten days. The nephroprotective effect of Nifedipine was assessed by a decrease in histological damage to the kidneys and the concentration of lead in kidney homogenate. Moreover, the levels of creatinine and blood urea nitrogen in the serum were also determined.
Data was examined as mean ± SEM (standard error mean). Data was statistically analyzed using one way analysis of variance (ANOVA). Statistical significance was considered at P < 0.05.
The current study showed reduction in the concentration of lead in kidney homogenate in nifedipine treated groups compared to control positive. The lead concentration in kidney homogenate was less in the control negative group than control positive group. The level of serum creatinine and blood urea nitrogen was remarkably increased in the control positive group as compared to the control negative group. Moreover the treatment with nifedipine decreased the levels of creatinine and blood urea nitrogen in serum. Histopathological study of the kidney tissue also showed that nifedipine could improve the lead induced injury in mice
It was concluded from this experiment that nifedipine has potential to minimize the lead induced nephrotoxicity in mice, as indicated by the lead concentration in kidney homogenate, serum creatinine and blood urea nitrogen levels and histopathological examination.
It is, therefore recommended that nifedipine can further be investigated for nephroprotective effects against heavy metal toxicities in other animal species including livestock.
