Objective : The purpose of this research is to examine the effects of Scutellariae Radix(SR) extract on immune cells in ovalbumin(OVA)-induced asthmatic mice. Methods : In vitro, C57BL/6 mice were exposed to OVA for 6 weeks. The mice lungs were taken out, chopped, grinded with collagenase and activated by rIL-3/rIL-5. The lung cells were treated with SR extract and analyzed by a flow cytometer. Results : The population of granulocytes/lymphocytes, CD3e-/CCR3+, CD69+/CD3e+, CD23+/B220+, CD4+ cells in the SR group in vitro decreased and population of CD8+ cells in the 100 and $10{\mu}g/m{\ell}$ SR group in vitro decreased, compared with that of control group. Conclusion : The results of this study support a role for SR as an effective treatment for asthma in its experimental success in significantly decreasing inflammation and asthma reactions.

The dynamic interactions between benzoic acid derivative ($pH{\approx}7.0$)(guest) and ${\beta}$-cyclodextrin (${\beta}$-CD)(host) were investigated in an aqueous solutions in terms of ultrasonic absorption in the frequency range 0.2 MHz ~ 50 MHz with emphasis on the low-frequency range below 1 MHz at $25^{\circ}C$. We show that the interaction of ${\beta}$-CD and benzoic acid derivative complies with a typical spectrum of a single relaxation process around a few MHz. The ultrasonic relaxation observed in these solutions was due to a perturbation of a chemical equilibrium related to a reaction of an inclusion complex formed by the host and guest. The rate constant ($k_b=7.48{\times}10^6M^{-1}s^{-1}$) and equilibrium constant ($K=68.6M^{-1}$) were determined from the concentration dependences of benzoic acid on the relaxation frequency. The standard volume change (${\Delta}V=10.6{\times}10^{-6}m^3mol^{-1}$) of the reaction was also computed from the maximum absorption per wavelength. It was found that the hydrophobicity of guest molecules played an important role in the formation of the inclusion complex.

The inclusion compound constituted with three-dimensional metal-complex $Cd(pn)Ni(CN)_4$ has been prepared and determined the crystal structure from single crystal X-ray diffraction data. Crystal data are as follows: $[Cd(pn)Ni(CN)_4]{\cdot}0.5(CH_3COCH_3{\cdot}H_2O)$, Fw = 387.35, Orthorhombic, $Pn2_1a$, a = 13.950(3) $\AA$, b = 26.713(7) $\AA$, c = 7.628(1) $\AA$, V = 2843(1) $\AA^3$, Z = 4, $D_x=1.81 gcm^{-3}$, $\mu(MoK{\alpha})$ = $28.153 cm^{-1}$, T = 297K, final R = 0.0418 for 3521($F_0>3{\sigma}(F_0)$). The metal-complex host provides tunnel cavity, similar to thiourea inclusion compounds, accommodated guest molecules $(=CH_3COCH_3\;and\;$H_2O).$ The stoichiometric host: guest ratio is 0.5. The title inclusion compound reveals another evidence for the host-selectivity, that is, the branched aliphatic guest molecule leads T-type host structure.

Porous nanosilica (PNS) has been identified as a potential candidate for controlled drug delivery. However, unmodified PNS-based carriers exhibited an initial release of loaded bioactive agents, which may limit their potential clinical applications. In this study, the surface of PNS was functionalized with adamantylamine (ADA) via disulfide bonds (-S-S-), PNS-S-S-ADA, which was then modified with cyclodextrin (CD)-heparin (Hep) (CD-Hep), PNS-S-S-CDH, for redox triggered rhodamine B (RhB) delivery. The obtained samples were then characterized by proton nuclear magnetic resonance ($^{1}H\;NMR$), Fourier transform infrared (FTIR), and transmission electron microscope (TEM). These results showed that PNS-S-S-CDH was successfully formed with spherical shape and average diameter of $45.64{\pm}2.33nm$. In addition, RhB was relatively encapsulated in the PNS-S-S-CDH (RhB@PNS-S-S-CDH) and slowly released up to 3 days. The release of RhB, in particular, was triggered due to the cleavage of -S-S- in the presence of dithiothreitol (DTT). It might be anticipated that the modified PNS can be used as redox-responsive drug delivery system in cancer therapy.

This experimental study was carried out to evaluate the effects of Acanthopanacis cortex on Cytokine-inducing and and immune response in Mice. In order to investigate the effect of Acanthopanacis cortex, the following was performed; Cytotoxicity, in vitro, the fraction of $CD4^+$, $CD8^+$, $B220^+$ in splenic cell, gene expression of IL-12(p35), IL-12(p40), IFN-${\gamma}$, and splenic cell proliferation by Acanthopanacis cortex. Analysis of cytokine gene expression was carried out by RT-PCR amplification. Amplified PCR products were electrophoresed on 1.2% agarose gel, and the analysis (Ht) was used to 1D-density program. The results were obtained as follows. Acanthpanacis cortex showed didn't have cell toxicity under $12{\mu}g/m{\ell}$ group on mouse lung fibroblast cells. In an in vitro model using mouse peripheral blood mononuclear cells (PBMCs), extract of Acanthpanacis cortex induced multiple cytokine, including interleukin-12 (p35), interleukin-12 (p40), interferon-gamma (IFN-${\gamma}$). The extract also enhanced the percentages of the $CD4^+$, and $CD8^+$ in the untreated control were $22.1{\pm}3.3$ to $38.4{\pm}2.1$, and $5.0{\pm}0.4$ to $10.7{\pm}0.3%$, respectively. From above findings, it is suggested that Acanthopanacis cortex is able to anti-cancer and activate immune response system.

Lipopolysaccharide binding protein (LBP) and CD14 protein play important roles in the defense against infection of Gram-negative bacteria. In the present study, tissue distribution and polymorphism of porcine LBP and CD14 genes were analyzed. Real-time PCR results showed that the porcine LBP gene was especially highly expressed in liver, while CD14 gene was highly expressed in liver and spleen tissues. A 1,732 bp cDNA fragment of porcine LBP gene and a 1,682 bp genomic DNA fragment of CD14 gene were isolated. Polymorphisms were identified in these two fragments and showed that there were 14 potential SNPs in the porcine LBP gene and 3 potential SNPs in the porcine CD14 gene. Three SNPs, 292G/A (Gly/Ser), 1168G/A (Ala/Thr) of the LBP gene and -61G/A of the CD14 gene, were genotyped using restriction fragment length polymorphism (RFLP) method. Association analyses indicated that polymorphism of the 292G/A locus was significantly associated with porcine immune traits hematocrit (HCT), IgG and delayed-type hypersensitivity (DTH) (p<0.01), and the 1168G/A locus was significantly associated with HCT and mean corpuscular volume (MCV) traits (p<0.05). No significant association was found between the -61G/A locus and immune traits of the pig. Our data indicated that the LBP gene was significantly associated with immune traits of pig. Also, we identified some SNPs which may be useful markers for disease-resistant breeding of pigs.

Background: Aberrant phenotypes in acute leukemia have variable frequency and their prognostic and predictive relevance is controversial, despite several reports of clinical significance. Aims: To determine the prevalence of aberrant antigen expression in acute leukemia, assess clinical relevance and demonstrate immunophenotype-karyotype correlations. Materials and Methods: A total of 73 (40 AML and 33 ALL) newly diagnosed acute leukemia cases presenting to KAMC, Kingdom of Saudi Arabia, were included. Diagnosis was based on WHO criteria and FAB classification. Immunophenotyping by flow cytometry, conventional karyotyping and fluorescence in situ hybridization for gene rearrangements were performed. Results: Aberrant antigens were detected in 27/40 (67.5%) of AML and in 14/33 (42.4%) in ALL cases. There were statistically significant higher TLC in Ly+ AML than in Ly-AML (p=0.05) and significant higher blast count in ALL with aberrant antigens at presentation and day 14 (p=0.005, 0.046). There was no significant relation to clinical response, relapse free survival (RFS) or overall survival (p>0.05), but AML cases expressing ${\geq}2$ Ly antigens showed a lower median RFS than those expressing a single Ly antigen. In AML, CD 56 was expressed in 11/40. CD7 was expressed in 7/40, having a significant relation with an unfavorable cytogenetic pattern (p=0.046). CD4 was expressed in 5/40. CD19 was detected in 4/40 AML associated with M2 and t (8; 21). In ALL cases, CD33 was expressed in 7/33 and CD13 in 5/33. Regarding T Ag in B-ALL CD2 was expressed in 2 cases and CD56 in 3 cases. Conclusions: Aberrant antigen expression may be associated with adverse clinical data at presentation. AML cases expressing ${\geq}2$ Ly antigens may have shorter median RFS. No specific cytogenetic pattern is associated with aberrant antigen expression but individual antigens may be related to particular cytogenetic patterns. Immunophenotype-karyotype correlations need larger studies for confirmation.

Various related factors and tissue changes in vitro and in vivo were observed to investigate the efficacy of HYBH on atopic dermatitis. The results are described below. HYBH improved the atopic dermatitis symptoms by naked eye examination, and significantly decreased dermatitis clinical index at 14 weeks. HYBH significantly decreased CD4+/CD45+, CD4+, CD8+, CD3+/CD69+ immune cell ratios in PBMC by 28%, 16%, 30%, 26% and 22% respectively. HYBH significantly decreased CD11b+/Gr-1+, CD3 immune cell ratios in dorsal skin by 35.3% and 67.5% respectively. HYBH significantly decreased the expression of IL-4 and IFN-${\gamma}$ in spleen by 23% and 15% respectively. HYBH significantly decreased the production rate of IL-5, IL-13 and histamine in serum by 17%, 23%, and 8.8% respectively and increased IL-17 production by 17%. HYBH significantly decreased immunoglubulins IgG1 and IgE production in serum. The results above indicated that treatment of HYBH improved atopic dermatitis symptoms by anti-oxidant activity and immune modulation activity as a clinical evidence. Also, different fermentation conditions using various microbial strains should be accumulated as the clinical evidence for broad application in the future.

This experimental study was carried out to evaluate the effects of Kimchi intake of Acanthopanacis cortex extract (APCE) supplementation on cytokine-induction and immune response in mice. To study in experiments using male Balb/c mice fed Kimchi and Kimchi of APCE supplementation (addition of 2% of total Kimchi weight) containing fed experimental diet during 2 weeks. Experimental mice were fed control diet or diet containing freeze-dried Kimchi at the level of 5%(w/w) or 5% freeze-dried Kimchi with 2% APCE supplementation. The main ingredient of Kimchi was Korean cabbage and fermentation was carried out at $4^{\circ}C$ for three weeks. Freeze-dried 2% APCE supplementation was added to Kimchi at the begining of fermentation. In order to investigate the effect of Kimchi intake of APCE supplementation (5%Kimchi-2%APCE), the following was performed; body weight, food intake, hematological parameter, serum level of mouse interleukin-4 (mlL-4) and mouse interferon-$\gamma$ (mIFN-$\gamma$ ), and, the percentage of CD3+/CD4+, CD3+/CD8+, B220+ in splenic cells. The results of final body weight, and food diet intake of two Kimchi groups were lower than those of the control group (not supplemented experimental diet). The hematology change obtained from the level of WBC (white blood cell) and platelet were not affected by feeding different dietary regiments, but the level of RBC (red blood cells) HB (hemoglobin), and spleen weight of two Kimchi groups were increased significantly than those of the control group. The serum level of IL-4 and IFN-$\gamma$ of two Kimchi groups were increased significantly than those of the control group, also enhanced the percentages of the CD3+/CD4+ and CD3+/CD8+ by 5% freeze-dried Kimchi, and 5%Kimchi-2%APCE group were 43.9 and 65.2%, and 96.0 and 208% than those of the control group, respectively. From these results, it can be concluded that Kimchi itself has an immuno-stimulatory effect and Kimchi contaning 2% APCE supplementation has the more pronounced effect in vivo system.
