초록

본 연구의 목적은 납중독에 의한 신장 기능 손상에 대한 스쿠알렌의 효과를 관찰하고자 하였다. ICR계 건강한 생쥐를 사용하여 납과 스쿠알렌을 복강 투여한 후, NO와 조직학적 변화를 관찰하였다. 실험군 설정은 다음과 같다. 실험군 1은 정상군, 실험군 2는 납 (30 mg/kg)만 처치한 군, 실험군 3은 납을 처치하고 스쿠알렌 (180 mg/kg)도 함께 처치한 군으로 각 실험군 당 생쥐 10마리를 사용하였다. 결과는 다음과 같다. 실험군 2의 경우, 미토콘드리아 신장, 사립체내막의 파괴, 소포체에서 리보소옴의 탈락이 24, 48시간동안 관찰되었고, 72시간부터 서서히 회복 되는 것을 관찰할 수 있었다. 실험군 3의 경우 실험군 2에 비해 손상 정도가 덜 하였으며, 48시간 이후부터 정상군과 유사한 소견을 보였다. NO의 경우 실험군 2에서는 NO 수치가 감소하였다. 하지만, 실험군 3의 경우 정상군보다 NO가 증가하였을 뿐만 아니라 납에 의한 NO 수치 감소에 대해 회복 효과를 보였다. 위와 같은 결과로 보아, 스쿠알렌이 신장 근위세뇨관에 미치는 납 독성을 감소시키면서 빠른 회복에 효과가 있을 것으로 사료된다.

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.
