Abstract
This study was designed to investigate the effect of Korean traditional tea materials on lead (Pb) accumulation and histological changes in Pb-administered rats. Male rats were divided into six groups: a normal, Pb, and Pb-water extract of Korean traditional tea materials (green tea: GT, persimmon leaf: PL, safflower seed: SS, Eucommia ulmoides: EU) groups. Pb (25 mg/kg BW) was orally administered once a day for 4 weeks. The extract of GT, PL, SS, and EU were administered based on 1.26 g of raw traditional tea materials/kg Bw/day. Pb contents of serum and liver were significantly higher in the Pb group than in the normal group. However the water extracts of GT, PL, SS, and EU administration lowered Pb contents of serum and liver in the Pb-administered rats, respectively. Serum Zn content was significantly higher in the Pb group than in the normal group, whereas, Cu and Fe contents were lower in the Pb group. Hepatic Ca content was significantly lower in the Pb group compared to the normal group. In the present study, water extract of Korean traditional tea materials administration effectively improved Cu and Fe contents of serum and liver. Infiltration of the local inflammation was found in Pb group, whereas water extracts of Korean traditional tea materials administration attenuated histological changes of tissues.
