        Isoniazid와 Nitrofurantoin으로 유발되는 간 세포독성에 대한 식물추출물의 보호효과

        Isoniazid was discovered in 1950’s and since then it has been widely used as a synthetic bactericidal agent in the treatment of tuberculosis. However, the adverse effect of isoniazid has been reported to show significant hepatotoxicity in approximately 1-2% of patients. Nitrofurantoin {1-(5-nitro-2-furfurylideneamino)-hydantoin} is a synthetic nitrofuran that is commonly used for the treatment and prophylaxis of urinary tract infections, but its use is associated with liver cirrhosis and fatal liver necrosis. Therefore, studies for natural products with protective effect on the isoniazid- and/or nitrofurantoin-in duced hepatotoxcity would be valuable as the potential therapeutic use. 107 plants sources were collected at Mt. Baekdu, and extracte d with methanol. These extracts had been screened for the protective effects against isoniazid- and/or nitrofurantoin-induced cyt otoxicity in HepG2 cells at the both 100 and 300 µg/ml. Five methanolic extracts, Acanthopanax senticosus, Acer mono, Asparagus schoberioides, Fagopyrum tataricum, Potentilla centigrana, showed significant protective effects against isoniazidinduced hepatotoxicity. Two methanolic extracts, Acer mono and Leonurus artemisia, showed significant protective effects against nitrofurantoin-induced cytotoxicity in HepG2 cells.
