Cyclodextrin glucanotransferase (EC 2.4.1.19, abbreviated as CGTase) is one of the most applied industrial enzymes that produces cyclodextrins from starch and related ${\alpha}$-1,4-glucans by intramolecular transglycosylation reaction upon Ca$\^$2＋/ dependent manner. The reaction of CLEC, ${\alpha}$-CGTases from Bacillus macerans with the soluble starch as a substrate reveals that the surfactants (SDS, N-octyl-${\beta}$-D-glucoside) significantly affect not only the overall products of CDs but also their selectivity. The surfactants (SDS, Lubrol PX) trigger the increase of ${\alpha}$-CD production, but Triton x-100 and Tween 80 suppress ${\alpha}$-CD specificity. Organic solvents (dimethyl sulfoxide, formamide, 2-methyl-2,4-pentandiol, and ethylene glycol) also cause changes of total product and product selectivity.

Background: This present study was conducted to evaluate the anti-inflammatory and immune regulatory effects of Aucklandia lappa Decne (AL). Methods and Results: We measured cytotoxicity, nitric oxide (NO) content, mRNA expression (iNOS, IL-1${\alpha}$, IL-$1{\beta}$, and TNF-${\alpha}$), protein expression (iNOS, COX-2, and $I{\kappa}B$) and phagocytic activity in RAW264.7 cells. Male BALB/c mice were fed 100 mg/kg AL (Aucklandia lappa Decneon 70% ethanol extract) and 250 mg/kg AL for 4 weeks; thereafter, we observed B/T or $CD4^+/CD8^+$ lymphocyte subpopulation change, and expression patterns of $CD4^+$ and $CD8^+$ lymphocytes by immunohistochemical staining in mouse splenocytes and/or thymocytes. To determine the experimental concentration of AL, cell viability was measured by MTT assay and tested at $12.5{\mu}g/m{\ell}$ or less. AL inhibited the levels of NO, lymphokine production (IL-$1{\beta}$, and TNF-${\alpha}$), and mRNA (iNOS, IL-1${\alpha}$, IL-$1{\beta}$, and TNF-${\alpha}$) and protein (iNOS, and COX-2) expression. Additionally, the levels of $I{\kappa}B$, phagocytic activity, and splenic and thymic T lymphocytes, especially $T_H$ and $T_C$ cells were significantly increased in AL administered mice. The immuno-reactive density of $CD4^+$ and $CD8^+$ lymphocytes was stronger in AL groups than in the normal group. AL stimulated NO, iNOS, and COX-2, and regulated IL-1${\alpha}$, IL-$1{\beta}$, TNF-${\alpha}$, and $I{\kappa}B$ in macrophages treated with LPS (lipopolysaccharide). In addition, AL increased the phagocytic activity of macrophages and the immunity of mouse T ($T_H$, and $T_C$) cells. Conclusions: These results suggested that AL might show anti-inflammatory activity via the suppression of various inflammatory markers and immuno-regulatory activity.

Inclusion complexes of ketoconazole(KT) with ${\alpha}^_$, ${\beta}^_$cyclodextrin(CD) and $dimethy1-{\beta}-cyclodextrin$ (CD) and $dimethy1-{\beta}-cyclodextrin(DM{\beta}CD)$ as nasal absorption enhancer were prepared in 1: 2 molar ratios by freeze-drying and solvent evaporation methods. In order to compare with the intrinsic absorptivity of KT in the jejunum(J) and the nasal cavity(N), the in situ simultaneous perfusion method was employed. The in situ recirculation study revealed that KT-CD inclusion complexes with the greater stability constant and the faster dissolution rate proportionally increased the absorption of KT in the J and N of rats. The rank order of apparent KT permeability$(P_{app}\;:\;cm/sec\;{\time}\;1O^{-5}{\pm}S.E.)$, corrected by surface area of absorption, was $5.10{\pm}0.3(N,\; KT-DM{\beta}CD)$ )> $4.13{\pm}0.4(N,\;KT-{\beta}-CD)$ )> $3.52{\pm}0.2(N,\;KT-{\alpha}-CD)$ )> $2.76{\pm}0.3(J,\; KT-DM{\beta}CD)$ )> $2.61{\pm}0.5(J,\;KT-{\beta}-CD)$ )> $2.42{\pm}0.4(J,\;KT-{\alpha}-CD)$ at pH 4.0. The in crease in permeability of $KT-DM{\beta}CD$ inclusion complex was 2.6 folds in the J and 4.5 folds in the N when the perfusing solution was changed from the buffer(pH 4.0) to saline. The absorption rate of $KT-DM{\beta}CD$ inclusion complex after nasal administration was more rapid than those of ketoconazole alone and $KT-DM{\beta}CD$ inclusion complex after oral administration to rats. In comparision with an oral administration of ketoconazole suspension in corn oil, the relative bioavailability was calculated 137.3% for the oral and 195.0% for nasal $KT-DM{\beta}CD$ inclusion complex in rats. The present results suggest that $KT-DM{\beta}CD$ inclusion complex may serve as a potential nasal absorption enhancer for the nasal delivery of ketoconazole.

Objectives: The purpose of this study wasto examine the effects of Kamijihwang-tang (KJHT) extracts on immune cells and cytokines in ovalbumin (OVA)-induced asthmatic mice. Methods: C57BL/6 mice were injected, inhaled and sprayed with OVA for 12 weeks (four times a week) for asthma induction. Two experimental groups were treated with different concentrations of KJHT (400 mg/kg and 200 mg/kg) extracts and cyclosporine A (10 mg/kg) for the later 8 weeks. At the end of the experiment, the mice lung, PLN and spleen were removed and immune cells were analyzed by flow cytometer, IL-5, IL-13, eotaxin-2, $TNF-{\alpha}$ were analyzed by real-time PCR, serum histamine was analyzed by ELISA kit. Results: $CD3^+$, $CD3e^-/CCR3^+$, $CD3e^+/CD69^+$, $CD4^+/CD25^+$, $B220^+/IgE^+$, and $CD3e^+/DX5^+$ cells in lung, PLN, and spleen of the KJHT group (400 mg/kg) decreased compared with that of the control group. $CD3e^+/CD69^+$, $CD4^+/CD25^+$, and $CD3e^+/DX5^+$ cells in lung, PLN, and spleen of the KJHT group (200 mg/kg), CD3+, $CD3e^-/CCR3^+$ cells in lung and PLN of the KJHT group (200 mg/kg) and $B220^+/IgE^+$ cells in lung and spleen of the KJHT group (200 mg/kg) decreased compared with that of the control group. mRNA expression of IL-5, IL-13, eotaxin-2, and $TNF-{\alpha}$ in lung tissue of the KJHT groups (400 mg/kg and 200 mg/kg) decreased compared with that of the control group. Histamine in serum of the KJHT group (400 mg/kg) decreased compared with that of the control group. Conclusions: These results suggest that KJHT can be utilized effectively in treating asthma because it significantly reduces inflammatory cells and cytokines.

CD1d expressing dendritic cells (DCs) are good glyco-lipid antigen presenting cells for NKT cells. However, resting B cells are very weak stimulators for NKT cells. Although ${\alpha}$-galactosylceramide (${\alpha}$-GalCer) loaded B cells can activate NKT cells, it is not well defined whether B cells interfere NKT cell stimulating activity of DCs. Unexpectedly, we found in this study that B cells can promote Th1-skewed NKT cell response, which means a increased level of IFN-${\gamma}$ by NKT cells, concomitant with a decreased level of IL-4, in the circumstance of co-culture of DCs and B Cells. Remarkably, the response promoted by B cells was dependent on CD1d expression of B cells.

Reactive humsn mesothelial cells were examined by immunocytochemical stain with intermediate filaments (cytokeratin [CK1, CK7, CK8, CK18, CD19), vimentin, desmin, actin), epithelial membrane antigen, carcinoembryonic antigen (CEA), MHC class II antigen (HLA-DR), LeuM-1 (CD15), $\alpha1-antitrypsin$(ACT), $\alpha1-antichymotrypsin$ (ACHT), CD68(KP-1) and FcyRIII(CD16). The mesothelial cells were isolated from patients with liver cirrhosis and pleural effusion, and short-term cultured in RPMI 1640 media containing 10% heat inactivated fetal calf serum and 1% identical supernatant fluid of the patients' transudates. The results obtained are as follows 1. The cultured-reactive mesothelial cells were positive for the protein of cytoskeleton such as cytokeratin and vimentin, but negative for desmin and actin. The resting mesothelial cells showed positive reactions for cylokeratin, but negative for vimentin, desmin and actin. 2. The primary antibodies to the cytokeratin were strongly reactive for CK1, CK8 and CK18 but negative for CK7 and CK19 in both reactive and resting mesothelial cells. 3. Resting mesothelial cells showed negative reactions for CEA, but strong positive reactions in cultured-reactive mesothelial cells. 4. The markers for the monocytes/histiocytes(CD11b, CD14, CD16, CD68, Iysozyme and $\alpha1-antitrypsin$ and $\alpha1-antichymotrypsin$) were nonreactive in resting mesothelial cells, but lysozyme and $\alpha1-antitrypsin$ were weakly reactive in reactive and proliferative mesothelial cells. 5. MHC Class II molecule(HLA-DR antigen) was negative in both resting and reactive mesothelial cells. These results suggest that the short-term cultured, reactive mesothelial cells show a newly aberrant expression of the vimentin and calcine-embryonic antigen. The reason of the aberrant expression of the intermediate filament and oncofetal antigen in reactive and proliferative mesothelial cells should be further evaluated.

Direct synthesis of cyclodextrin (CD) from extruded insoluble corn starch without liquefaction procedure using cyclodextrin glucanotransferase (CGTase) was carried out. Increased CD production rate and yield were achieved in heterogeneous enzyme reaction system containing extruded corn starch compared with those of conventional system employing liquefied or partially cyclized starch. At extruded starch concentration of 100 g/l the CD concentration and conversion yield were reached up to 54 g/l and 0.54, respectively. High purity of $\alpha \beta \gamma$-CDs without accumulation of undesirable malto-oligosaccharides was produced, furthermore, the residual extruded starch was easily separated by centrifugation from reaction mixture, whlch will facilitate the purification procedure. Granular structure of extruded starch was observed by SEM to investigate enzyme reaction mechanism. Supplemental addition of $\alpha$-amylase enhanced slightly the initial CD production rate, but it decomposed produced CD at the late stage. Various! extruded raw starches, such as, corn, rice, and barley were also suitable substrates for CD production.

The studies on the adsorption properties and the antibacterial effects of the Cd and Cu-treated activated carbon were carried out. From the adsorption studies on the series of these metal-treated activated carbons, typical Type-I isotherm was observed. The surface areas of the treated carbon obtained from BET equation were in the range of $1101-1418m^2/g$ for Cd-AC and of $1084-1361m^2/g$ for Cu-AC. Using ${\alpha}_s$-plot, the micropore volumes and pore size distribution were obtained. From the SEM study, it is also observed that many of micropores in activated carbon are blocked by window blocking effect of metals after the impregnation. Finally, antibacterial effects of M-activated carbon against Escherichia coli was discussed. From the study, the area of antibacterial activity becomes larger with the increase of the amount of metal treated.

In the present study, we exarnined anti-allergic effect of SGBHB in cultured B cells. B cells were prepared from isolated murine splenocytes and activated by co-treatment of anti-CD40 monoclonal antibody and recombinant IL-4 allergens. Anti-allergic effects of SGBHB in activated B cells were determined by measuring B cell surface activated molecules (CD23+ and CD11a+), and expression levels of IL-$1{\beta}$, IL-6, IL-10, TNF-$\alpha$, IgE, and HRF. The major findings are summarized as follows. 1. SGBHB treatment did not produce significant cytotoxic effects on mouse lung fibroblast cells. 2. SGBHB produced significant inhibitory effect on the expression of B cell surface activated molecules (CD23+ and CD11a) in activated B cells. 3. SGBHB treatment significantly inhibited expression levels of IL-$1{\beta}$, IL-6, and TNF-$\alpha$ mRNAs in activated B cells.IL-6 protein levels were significantly decreased by $100{\mu}g/m{\ell}$ of SGBHB treatrrient, and TNF-$\alpha$ protein levels were decreased compared to the control group, but statistically insignificant. 4. SGBHB treatment significantly increased IL-10 at both mRNA and protein levels in activated B cells. 5. SGBHB treatment significantly inhibited levels of IgE production. Thus, the present data suggest that SGBHB has an anti-allergic effect on activated B cells by controlling irnmune responses, and further implicates the possibility on clinical application as a therapeutic agent.
