To investigate the effect of the squalene against the lead toxicity and recovery of renal failure. Healthy male ICR mice were used for experiment. The activity of nitric oxide (NO) was observed after the intraperitoneal injection in mice. The ultrastructural changes of the kidney were observed after the intraperitoneal injection of lead acetate in mice. The experimental groups were divided into three groups. Group 1 was normal mouse. Group 2 was not treatment with squalene after intraperitoneal contamination of lead acetate (30 mg/kg). And, Group 3 was injected squalene (180 mg/kg) after intraperitoneal contamination of lead acetate. All groups were used to 10 mice. The results were as follow: In the case of the group 2, swelling of the outer membrane and destruction of the inner membrane (cristae) of the mitochondria, dripping of the ribosomes from the rough endoplasmic reticulum were happened at 24 hours and 48 hour. These were gradually reparied after 72 hours. In the case of the group 3, damages of the mitochondria and the rough endoplasmic reticulum were showed less than the group 2 at 24 hours. Especially, after 48 hours, these were almost same as the group 1. In the case of group 2, the level of NO was decreased. However, In the case of group 3, the level of NO was increased more than normal as well as repaired the decreased NO level by Pb (P<0.05). It was concluded that the squalene was the protective and recovery effects for the toxicity of the lead in the renal proximal tubules.
