Abstract

BACKGROUND: The purpose of this study was that serum metabolic and hematological variables were measured to investigate the detoxication effect of Taraxacum mongolicum extract on male albino rat exposed with lead and mercury. METHODS AND RESULTS: For this study, Pb and Hg-exposed( 50 ppm) albino rats was used, and the treatments were carried out in three doses of 100 mg/kg, 200 mg/kg and 500 mg/kg as dry weight of T. mongolicum extract. T. mongolicum extract could improved the body weight gain and feed efficiency ratio, except to food intake. The levels of biochemical factors elevated by Pb-Hg mix exposure, which are Bilirubin, Alkaline phosphatase(ALP), glutamic oxaloacetate transaminase(GOT), glutamic pyruvate transaminase (GPT), lactate dehydrogenase(LDH), ceatinine and blood urea nitrogen(BUN), were significantly reduced in all treated groups as compared to Pb-Hg mix exposure alone. T. mongolicum extract was shown to suppress the accumulation of Hg and Pb in serum by dose dependent manner. CONCLUSION: Therefore, this study suggest that T. mongolicum extract might have the potential effect to minimize the toxic effects of Pb and Hg.

본 연구에서는 포공영의 에탄올 추출물의 중금속 중독에 의한 손상 억제 효과를 측정하였다. 현대 사회에서 환경으로부터 오염이 우려되는 납과 수은을 실험동물에 노출시켰고, 납과 수은에 노출된 흰쥐에서 포공영이 이러한 중금속 노출로 영향을 받는 체중변화, 간 및 신장에 미치는 영향을 혈액세포분석 및 혈액 내의 생화학적 분자에 대한 조사하였다. 실험 결과, 포공영을 투여 받은 실험군은 중금속 투여로 인하여 발생하는 체중감소의 개선효과가 나타났고, 혈액세포의 변화에 있어서도 중금속 노출로 감소되었던 RBC의 수를 증가시켰고, 증가된 WBC 및 platelet의 수를 정상수준으로 회복시켰다. 간 및 신장의 손상 지표들로 측정한 Bilirubin, ALP, GOT, GPT, LDH, ceatinine 및 BUN에 있어서도 중금속 노출로 증가된 수치를 농도의존적으로 감소시켰다. 또한 혈액내에서의 중금속 잔존량을 측정한 결과, 포공영 추출물 투여로 인하여 농도의존적으로 그 잔존량이 감소하였다. 따라서, 포공영 에탄올 추출물은 체내 노출된 납과 수은에 대한 독성을 완화시켜주는 것으로 사료된다.
