다국어 초록 (Multilingual Abstract)

For investigation of the activated carbon on the mouse kidney treated with Pb, the activated carbon (40 mg/kg) and Pb (30 mg/kg) were treated orally for three and six weeks, respectivelly, and observed by the electron microscope. On the glomerulus of the group with only Pb, the basal membrane thicked, projected, and the foot processes fused. On the proximal convoluted tubules, the number of microvilli were decreased and the number of vacuoles and lysosome increased on the cytoplasm. The mitochondria and endoplasmic reticulum were extended and ribosomes dropped from the ER. On the giomerulus of the group with Pb-activated carbon, the basal membrane and the foot processes were merely changed. On the proximal convoluted tubules, the shapes and number of microvilli were not changed and the number of vacuoles, microbodies, and lysosomes decreased. The shapes of mitochondria and endoplasmic reticulum observed almost similar with control group. Th at is, elongated mitochondria and attached ribosomes to endoplasmic reticulum. As result, the activated carbon has positive effect on reducing toxicity of lead in the mouse kidney in the view of electron microscope.
