Abstract

This study aimed to investigate the protective effect of Solanum nigum Linne total extract (SNT), Solanum nigum Linne leaf extract (SNL), Solanum nigum Linne root extract (SNR) on liver injury induced by Lipopolysaccharide(LPS) in Sprague-Dawley rats. SNT, SNL, SNR of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 20 days. on the day 1.5 ml/kg of LPS was injected. Four hours later, they were anesthetization with ether and dissected. Glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT) were measured in serum and superoxide dismutase (SOD), catalase and glutathione peroxidase (GPX) were measured in liver homogenate. SNT, SNL, SNR extract inhibited GOT and GPT activities in LPS-induced rats, whereas increased SOD, Catalase and GPX activity in liver tissue of LPS-induced rats. These suggested that SNT, SNL, SNR could be used for functional beverage.

본 연구에서는 LPS를 투여시켜 간손상을 유발한 흰쥐의 간에서 까마중 추출물의 간손상 보호효과를 알고자 하기 위한 것이며, 이 물질을 천연 한방차로 개발하기 위한 기초자료를 얻고자 하였다. 본 실험에서는 생후 7주 암컷 흰쥐 총 35마리를 7마리씩 나누어 NOR, CON, SNT, SNL, SNR 5군으로 분리하여 실험하였다. 정상군은 20일 동안 1.5ml/kg of 0.9% saline을 투여하고 대조군은 20일 동안 1.5ml/kg of 0.9% saline을 매일 투여한 후 21일째 되는 날 LPS를 5 mg/kg의 농도로 만들어 1.5 ml/kg의 용량으로 복강 내로 투여하였다. 시료군(SNT, SNL, SNR)에는 100 mg/kg 농도의 각각의 분획을 1.5ml/kg씩 복강 내에 20일간 매일 투여하고 21일째 되는 날에 LPS를 1.5 ml/kg의 용량을 복강 내로 투여하여 희생시켰다. GOT, GPT는 혈청을 사용하여 측정하였고, SOD, catalase, GPx는 간 조직을 사용하여 실험하였다. SNT, SNL, SNR group들은 LPS로 유도된 쥐의 혈청에서 GOT와 GPT활성을 억제하였고, 반면에 SOD, catalse, GPx의 활성은 LPS로 유도된 쥐의 간 조직에서 정상의 수치로 높아졌다. 이것은 SNT, SNL, SNR들이 기능성 음료로서의 가능성이 보여진다.
