Many studies have provided evidences that hepatitis B surface antigen (HBsAg) including preS region could be an ideal candidate for a new hepatitis B virus (HBV) vaccine with higher efficacy. We established CHO cell lines, IY-CHO-2 and IY-CHO-11 expressing high levels of HBsAg containing preS2 and S protein by stable transfection method. These cell lines expressed the correct size (about 1 kb in length) of HBsAg mRNA as expected. The purified protein from the culture supernatants of the clones showed the same sizes as those expressed in native hepatitis B virus (24 kDa, 27 kDa, 34 kDa and 36 kDa). Antibody productivity of CHO-derived HBsAg protein at lower dose challenge was higher than the protein containing S region alone expressed in yeast system. These results indicate that CHO-derived HBsAg protein containing preS2 and S region can be effectively used for a better immune response as a HBV vaccine.

We investigated the characteristics of transformer type SFCL with neutral line. The transformer type SFCL having neutral line has achieved the simultaneous quench because the secondary winding has acted as parallel reactor. The fault current of SFCL was limited according to ratio of turn number between primary and secondary windings. Therefore, the power burden of superconducting element can be reduced by reduction of ratio of turn number between primary and secondary windings. As a result, we could expect reduction of it's volume in the transformer type SFCL.

The DNA sequence of the chitosanase gene (choK) from $\beta$-Proteobacterium KNU3 showed an 1,158-bp open reading frame that encodes a protein of 386 amino acids with a novel 74 signal peptide. The degenerated primers based on the partial deduced amino acid sequences from MALDI- TOF MS analyses yielded the 820 bp of the PCR product. Based on this information, double inverse PCR cloning experiments, which use the two specific sets of PCR primers rather than single set primers, identified the unknown 1.2 kb of the choK gene. Subsequently, a 1.8 kb of full choK gene was cloned from another PCR cloning experiment and it was then subcloned into pGEM T-easy and pUC18 vectors. The recombinant E. coli clone harboring recombinant pUC18 vector produced a clear halo around the colony in the glycol chitosan plates. The recombinant ChoK protein was secreted into medium in a mature form while the intracellular ChoK was produced without signal peptide cleavage. The activity staining of PAGE showed that the recombinant ChoK protein was identical to the chitosanase of wild-type. The comparison of deduced amino acid sequences of choK revealed that there is 92% identity with that of Sphingobacterium multivorum chitosanase. Judging from the conserved module in other bacterial chitosanases, chitosanase of KNU3 strain (ChoK) belongs to the family 80 of glycoside hydrolases.

This study was conducted to restore our traditional Cheongtaejeon tea and to develop the special products. We inoculated Cheongtaejeon tea with lactobacilli (Lactobacillus plantarum CHO 25) and the mixed microbial strains (L. plantarum CHO 25 + Saccharomyces cerevisiae + Bacillus amyloliquefaciens CHO 104). We also examined the sensuous characteristics and physiological activity of Cheongtaejeon tea which was produced by the inoculation of microbial strains. The external appearance of Cheongtaejeon teas were not significant among the teas which were produced with or without the inoculation of L. plantarum CHO 25 and the mixed microbial strains. The taste of the tea increased most in Cheongtaejeon tea which was produced without the inoculation of microbial strains. The taste and liking of Cheongtaejeon tea which was inoculated with Aspergillus oryzae and Aspergillus niger decreased significantly, and it was not suitable to drink. Total phenolics compound contents, total flavonoid contents and DPPH ($\alpha,\alpha$-diphenyl-$\beta$-picryl-hydrazyl) radical scavenging activity of Cheongtaejeon tea extracts increased much more in the order of that produced with the inoculation of L. plantarum CHO 25, control and that with the mixed microbial strains. However, nitrite radical scavenging activity in 1,000 mg/L Cheongtaejeon tea hot water extracts were in the order of the control (94.4%), the inoculation of L. plantarum CHO 25 (93.6%) and the mixed microbial strains (91.1%). Overall results indicated that the sensuous characteristics increased most in Cheongtaejeon tea which was produced without the inoculation of microbial strains, and those physiological activities in tea with the inoculation of L. plantarum CHO 25.

To evaluate an effect of cyclohexanone (CHO) treatment on the serum levels of glutathione S-transferase (GST) activity in acute liver damaged animals, acute liver damage was induced in rats with pretreatment of 50% $CCl_4$ in olive oil (0.1 ml/100 g body wt) intraperitoneally 14 times every other day. To liver damaged rats, CHO (1.56 g/kg body wt, i. p.) was injected once and then rats were sacrificed at 4 hours after injection of CHO. Increasing rate of GST activity to the control in serum was higher in CHO-treated rats pretreated with CCL$_4$ than the $CCl_4$-pretreated those. All the more, the injection of CHO to the liver damaged rats led to more enhanced liver damage on the basis of liver functional findings, i. e., serum levels of alanine aminotransferase (ALT) activity, liver weight per body weight, and malondialdehyde content. The changing pattern of serum ALT activity was similar with that of GST activity, whereas that of liver in both enzymes differed more or less from each other; the liver GST activity in CHO-treated rats pretreated with $CCl_4$ being more increased tendency than that of $CCl_4$-pretreated rats. Concomitantly the injection of CHO showed a increasing tendency of liver GST activity compared with the control. Furthermore, CHO injection to the liver damaged rats showed somewhat higher Vmax in the kinetics of liver GST enzymes. In conclusion, injection of CHO to the liver damaged animals led to more increased activity of serum GST, and it may be chiefly caused by the alteration of membrane permeability.

The relationship between dietary carbohydrate (CHO) and fasting triglyceride (TG) concentrations was examined in 2,689 men, 1,908 premenopausal women, and 966 postmenopausal women aged 20-69 years in the 1998-Korean Health and Nutrition Survey. The serum TG concentrations in fasting blood samples were measured and dietary CHO intake was assessed by using 24-hour recall method. As CHO intake increased, the TG concentrations were significantly affected (127.4 mg/dl, 132.4 mg/dl, 134.8 mg/dl, 142.6 mg/dl, 147.2 mg/dl) in postmenopausal women, while CHO intake was not significantly associated with TG concentrations in men and in premenopausal women. For the lowest to the highest quintiles of CHO, the mean TG concentrations were 120.0 mg/dl and 140.3 mg/dl in postmenopausal women with body mass index (BMI) ＜25 kg/m$^2$ and 135.6 mg/dl ＆ 155.3 mg/dl in postmenopausal women with BMI$\geq$25 kg/m$^2$. In multivariate analysis, BMI, waist hip ratio (WHR), glucose, smoking, and drinking habit were associated with serum TG concentrations in men. In premenopausal women, BMI, WHR, and glucose levels were associated with serum TG concentrations, while age, BMI, WHR, glucose levels, and CHO intake were associated with serum TG concentrations in postmenopausal women. In conclusion, CHO intake is related to serum TG concentrations in postmenopausal women in Korea.

'Ha Go Cho (夏枯草)' is one of the Chinese crude drugs used mainly as a diuretic. With regard to the botanical origin of 'Ha Go Cho', it was reported by Su et al. that those from China were originated from the fruited spica of Prunella vulgaris L. of Labiatae. It was, however, for the herba or spica of Prunella vulgaris L. var. lilacina Nakai from Korea. According to survey of markets in Korea, most of the materials collected in the markets seemed to be originated from Prunella plant, while some seemed to be Thesium plant of Santalaceae. To clarify the botanical origin of 'Ha Go Cho', the anatomical characteristics of Prunella vulgaris L. var. lilacina Nakai and Thesium chinense Turcz. were studied. As a result, it was clarified that some 'Ha Go Cho' from Korea were the herba or spica of Prunella vulgaris var. lilacina, whereas some others were the herba of Thesium chinense.
