Kinetic studies for the methanolysis of tert-butyl halides (t-BuCl, t-BuBr, t-BuI) were carried out in MeOH-1,1,2,2-tetrachloroethane mixtures. The solvatochromic comparison method was used with six indicators to analyze solvent effects on the ionizations of tert-butyl halides. It was shown that the cooperative effect of solvent polarity-polarizability was the most important factor influenced on the methanolysis rates of tert-butyl halides, but the electrophilic assistance for halide leaving group and the nucleophilic assistance for tert-butylium ion were considerably influential, too. And it was found that the electrophilic assistance caused by hydrogen bonding and the nucleophilic assistance for carbon center were stronger for more basic leaving group ($I^-) and more polarizable leaving group(t-BuCl

In order to establish the standard method for the preparation of processed Aconiti Tuber, Aconiti Tubers were processed under various conditions and the amount and the composition of alkaloids were determined by HPLC. The ratio of sum of benzoylhypaconine and benzoylmesaconine over the sum of acinitine, mesaconitine, benzoylmesaconine and benzoylhypaconine was used as a detoxification index ((BM+BH)${\times}$100/MA+AC+BM+BH). The adequate value of index was obtained from Japanese 'ka-gong bu-ja' which has been used in Japan. The processing procedure was largely devided into two categories. First is heat treating at $120^{\circ}$ and 1. 2 lbs for 60 min. Second is treatment with various kinds of alkaline solutions followed by heat treatment at $120^{\circ}$ and 1. 2 lbs for 60 min. Among the source of processed Aconiti Tubers, dried bu-ja and yom bu-ja, dried bu-ja was more adequate than yom bu-ja because yom bu-ja has the lower value of index than dried bu-ja and lost active components through the desalting periods. Dried bu-ja whish was treated with alkaline solutions followed by heat treatment has the detoxification index, 50% and dried bu-ja which was treated only with hear has 71. 8%. Compared to the value of index of Japanese 'ka-gong bu-ja', 72%, the dried bu-ja treated with heat at $120^{\circ}$ and 1, 2 lbs for 60min was the most adequate. The $LD_{50}$ value of the processed bu-ja was higher than 15 g crude drugs/kg, p.o. in mice.

Previously, we found that KTH-13 isolated from the butanol fraction of Cordyceps bassiana (Cb-BF) displayed anti-cancer activity. To improve its antiproliferative activity and production yield, we employed a total synthetic approach and derivatized KTH-13 to obtain chemical analogs. In this study, one KTH-13 derivative, 4-(tert-butyl)-2,6-bis(1-phenylethyl)phenol (KTH-13-t-Bu), was selected to test its anti-cancer activity. KTH-13-t-Bu diminished the proliferation of C6 glioma, MDA-MB-231, LoVo, and HCT-15 cells. KTH-13-t-Bu induced morphological changes in C6 glioma cells in a dose-dependent manner. KTH-13-t-Bu also increased the level of early apoptotic cells stained with annexin V-FITC. Furthermore, KTH-13-t-Bu increased the levels of cleaved caspase-3 and -9. In contrast, KTH-13-t-Bu upregulated the levels of pro- and cleaved forms of caspase-3, -8, and -9 and Bcl- 2. Phospho-STAT3, phospho-Src, and phospho-AKT levels were also diminished by KTH13-t-Bu treatment. Therefore, these results strongly suggest that KTH-13-t-Bu can be considered a novel anti-cancer drug displaying pro-apoptotic activity.

The former administration office building of Kyeong-seong-bu(京城府) was a building converted from the Japanese residency-general's of Kyeong-seong(京城理事廳) which was originally built as the Japanese consulate in Joseon(日本領事館). It was too worn and too small as a Kyeong-seong-bu administration office even with several annexes. Kyeong-seong-bu tried to build a new big administration office building at the vacant north side of the same site, which was closely faced to the rotary in front of the Bank of Joseon(朝鮮銀行前廣場). But this trial was ended in vain due to insufficient budget. Therefore Kyeong-seong-bu built a new administration office building in another site and moved to it in 1926 with debts. For paying for the debts Kyeong-seong-bu sold the former site after partitioning with new roads through it. As a result the nature of the former site and its surroundings was changed. This study traces the changes and inquires how the authorities in the colonial Joseon and various commercial powers of Kyeong-seong-bu behaved for their own interests in the meantime. It makes use of the historical records and documentary literatures between early 1910s and early 1930s.

Background and Objective : Keo-Bu-Saeng-Gi(去腐生肌) is the word meaning wound healing process of the skin disease. This study introduces the theory of Keo-Bu-Saeng-Gi that can be used for not only skin disease but also for rejuvenation, beauty care. Methods : We searched oriental literatures and reports related with Keo-Bu-Saeng-Gi(去腐生肌). Result and Conclusions : Many oriental literatures refered to Keo-Bu-Saeng-Gi(去腐生肌) as a wound healing mechanism of the skin disease. Wound healing is very important for skin disease and rejuvenation. We can use this theory of Keo-Bu-Saeng-Gi(去腐生肌) for skin care.

Sodium butyrate (NaBu) has been used to enhance protein expression levels in mammalian cell culture. To determine the clonal variability of recombinant Chinese hamster ovary (rCHO) cells in response to NaBu addition regarding specific antibody productivity $(q_{Ab})$, three rCHO clones were subjected to different concentrations of NaBu. For all three clones, NaBu addition inhibited cell growth and decreased cell viability in a dose-dependent manner. On the other hand, the enhancing effect of NaBu on $q_{Ab}$ varied significantly among the clones. NaBu addition enhanced the antibody production of only one clone. RT-PCR analysis revealed that the changes in $q_{Ab}$ correlated linearly with those of the mRNA transcription level. Thus, it was concluded that the different enhancing effects of NaBu on protein expression in rCHO cell clones resulted from their different mRNA transcription levels.
