Abeliophyllum distichum Nakai is a deciduous shrub of a flowering plant in Oleaceae. It is an important plant resource and consists of only one species in the entire world. A. distichum Nakai is well known an edible, medicinal herb in its habitat districts, but the toxicological evaluation for the safe use of its extract is still insufficient. The study characterized the toxicity of an Abeliophyllum distichum Nakai ethanol extract in Sprague-Dawley (SD) rats and determined the safe dosage levels in a 13 weeks toxicity study. Abeliophyllum distichum Nakai ethanol extract was orally administered once daily for 2 weeks at 0, 500, 1,000 and 2,000 mg/kg/day to male and female SD rats. while recording the clinical signs of toxicity, body weight, food intake/consumption, eye test and urine analysis. Only the total protein frequency in the urine of male SD rats (p<0.05), the right ovary of the 500 mg/kg group (p<0.01) and the right adrenal gland of the 1,000 mg/kg group (p<0.05) in the female rats showed statistically significant changes. But no toxic effects were noted from repeated-dose administration of the Abeliophyllum distichum Nakai ethanol extract in the SD rats during the observation period. The post-mortem examinations showed no test substance-mediated changes. The hematological analysis and clinical blood chemistry data demonstrated no toxic effects from repeated-dose administration of Abeliophyllum distichum Nakai ethanol extract in the SD rats during the observation period. Based on these results, this data suggests that a dose of 1,000 mg/kg/day is a highest treatment to administer when conducting a further 13 weeks toxicity study.

This study aims at developing for food education textbook and teaching aids of elementary school students and teaching guide book (of food exerts) for eco-friendly food education together with green growth to standardize food education and to make the best the effect of food education. Especially we will develope active food education program to which elementary school students study through developing various education textbook and teaching aids. Major contents of food education textbook in this study are classified as two subjects. First included the understanding of eco-friendly agricultural products, to distinguish the indication of eco-friendly agricultural products, merits of school feeding made by eco-friendly agricultural products. Second is about children loving earth to understand food mileage. Its contents are as follows ; the definition of food mileage, the movement of food mileage to report environment, origin mark of agricultural products, our mental attitude for our favorite agricultural products, the eco-friendly agricultural products of Gyeonggi Province
