  • Shenqi-wan, Oriental herbal medicine formulation, has traditionally been used for the treatment of delayed mental and physical development in children, complications of diabetes, and glomerulonephritis. In the present study, we investigated the protective effect of the aqueous extract of Shenqi-wan and its fractions against N-methyl-D-aspartate (NMDA)-induced exitotoxicity in rat hippocampal CA1 neurons. Fractions were elucidated at 0 - 10 min, 11 - 20 min, and 21 - 30 min by using gravity column chromatography method. In the present results, treatment with NMDA on cultured hippocampal slices induced neuronal death in the hippocampal CA1 region. Pretreatment with the Shenqi-wan did not exerted protective effect, however its fractions suppressed NMDA-induced neuronal damage. The fraction elucidated at 11 - 20 min showed the most potent protective effect. These results revealed that effective substances of the Shenqi-wan against NMDA-induced excitotoxicity may exist mainly in the fraction elucidated at 11 - 20 min.

  • Wan is a tableware in which boiled rice or soup, side dish are put, and it is a representative model which shows the development of personal tableware. From the establishing period of Hanseong Baekje, the form of wan which is Jung-do Style(中島式) Plain Pottery of previous period Proto-Three Kingdoms Period was succeeded to, but wan is produced and used as a wan baked in the kiln, which is far development of the producing technique including hardness and clay. By and large, the size of $0.3{\sim}0.4{\ell}$ was the majority and the production technique of wan which used carefully selected soft quality clay are largely confirmed to be two methods which are, first, basic method by which on a clay tablet on the rotating table, clay band is accumulated and moulding is finished, and second, the new method which had the same basic moulding as that of basic method but in the last stage takes wan off the rotating table and reverse it to trim the bottom and remove the angle of flat bottom. The former, basic production method is the classical production method since wan of Jung-do Style Plain Pottery and wan was produced and used for all periods of Hanseong Baekje. On the other hand, the latter is the production method obtained through form imitation of China made porcelain flowed into through interchange between Baekje and China, and through comparison with Chinese chronogram material it is estimated to have been produced and used after middle of 4th century. Therefore it can be known that the Baekje people's demand for China made articles was big and imitation pottery was produced and used with Baekje pottery. In addition, bowl with outward mouth are confirmed in multiple number in Lakrang(樂浪) pottery wan and it is assumed that wan was the form produced under the influence.
