The Mume Fructus (MF) has been used for relieves cough, arrests arrest chronic diarrhea, treat fluid depletion, and treat ascariasis in Korea. In this study, a high-performance liquid chromatography (HPLC) method was established for simultaneous determination of six main components of MF. Additionally, we were investigated the anti-inflammatory and anti-allergic effects of MF extract on lipopolysaccharide (LPS)-treated RAW264.7 cells and tumor necrosis factor (TNF)-${\alpha}$/interferon (IFN)-${\gamma}$-treated HaCaT cells. The analytical column for separation was used a Gemini $C_{18}$ column maintained at $40^{\circ}C$. The mobile phase consisted of 1.0% (v/v) acetic acid in water (A) and 1.0% (v/v) acetic acid in acetonitrile (B). The flow rate was 1.0 mL/min and the detector was a photodiode array (PDA) set at 280 nm and 320 nm. We evaluated the inhibitory effect of MF extract on the production of inflammatory markers, nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) in LPS-stimulated RAW264.7 cells and thymus- and activation-regulated chemokine (TARC/CCL17) in TNF-${\alpha}$/IFN-${\gamma}$-treated HaCaT cells, respectively. We confirmed the genes expression related with TARC, macrophage-derived chemokine (MDC/CCL22) and regulated on activation, normal T cell expressed and secreted (RANTES/CCL5) in HaCaT keratinocyte cells by MF extract. The contents of the five compounds in MF were 0.22-1.01 mg/g. Also, the MF extract show inhibition of about 78% and 75% on NO and $PGE_2$ production at the concentration 1000 mg/mL in RAW264.7 cells. MF extract suppressed the hTARC level and genes expression such as TARC, MDC, and RANTES on TNF-${\alpha}$/IFN-${\gamma}$-treated HaCaT cells.

Objective : Allergic rhinitis(AR) is an inflammation or irritaion of nasal mucosa. Usually, serum cytokine is regarded as one of the most important factors in AR. Coisis semen have been used for the diseases in digestive organs in traditional chinese medicine. Nowaday, there were some studies reported about the effects of coisis semens on serum cytokine. However the results of theses studies were varies, and moreover there was no study which have used AR animal model. Therefore this study is aimed to determine therapeutic effects of coisis semen extract by observing changes of serum cytokine(IgE, TNF-${\alpha}$, IL-$1{\beta}$, IFN-${\gamma}$ and IL-13) with AR animal model. Methods : Thirty BALB/c mice were divided into six groups : Normal group, Control group, sample I, sample II, sample III, sample IV. Except for Normal group, all the mice in other 5 groups were sensitized intraperionealy by 0.1% ovalbumin solution three times at intervals of one week. Then intranasal sensitization was performed by diffusing 0.1% ovalbumin solution three times at intervals of two days. Normal group were used Normal Saline instead of ovalbumin solution. After the first day of study, sample I, sample II, sample III, and sample IV were orally administrated coisis semen extract by 100mg/kg, 200mg/kg, 500mg/kg, and 1g/kg respectively for 28days. Then, the changes of serum IgE, TNF-${\alpha}$, IL-$1{\beta}$, IFN-${\gamma}$ and IL-13 were observed in 6 groups. We used the statistical methods of ANOVA, post hoc by duncun, and Kruskal-Wallis test(p<0.05) Results : There were statistical changes in IgE and TNF-${\alpha}$. But, there were no statistical changes in IL-$1{\beta}$, IL-13 and IFN-${\gamma}$. Conclusions : According to above results, it is supposed that coisis semen extract has not some significant effects on cytokine of AR animal model. There was no evidence for using coisis semen in relieving symptoms of allergic rhinitis.

Objectives : Atopic dermatitis(AD) is a chronic recurrent skin disease which usually developed in infancy or childhood. AD often repeat improvement and relapse. The cause of AD is so indefinite that many methods of therapies(moisturizer, steroid ointment, antihistamine, immunomodulator, immunosuppressant, herbal medicine, alternative medicine, etc.) are tried. Recently, a lot of studies were made. But there is no report about the effect of Samulsopungeum(SM) and Prednisolone(PN) on AD. So, author aimed to investigate the effects of SM and PN on AD of NC/Nga mice. Methods : Thirty two mice(8 Balb/c mice and 24 NC.Nga mice) were divided into four groups; Balb/c mice was normal group. NC/Nga mice were divide into three group : control, PN, SM group. AD was induced in the control, PN, SM group by spreading DNCB. Then normal saline, PN and SM were orally administered three times in a week for 8 weeks to the control, PN, SM group, respectively. We observed changes of clinical skin severity score, serum IgE, IgG1, IFN-$\gamma$, IL-2, IL-4, IL-5, IL-10, IL-13, and so on. We used one-way ANOVA test statistically(p<0.01). Results : The clinical skin severity scores of PN group and SM group in 8th week were decreased compared to the control group. Serum IgE, IgGl levels of PN group and SM group were significantly decreased compared to the control group. Serum IFN-$\gamma$ in SM group was significantly increased compared to the control group. But, Serum IFN-$\gamma$ in PN group was significantly decreased compared to the control group. Serum IL-10 levels of PN group and SM group were significantly decreased compared to the control group. Serum IL-2, IL-4, IL-5, IL-13 levels of PN group and SM group were significantly decreased compared to the control group. mRNA expression levels of IL-2, IL-4, IL-5, IL-13 in the dorsal skin tissues of PN group and SM group were significantly decreased compared to the control group. According to biopsy reports of the ear and skin tissues showed that the tissue damage of PN group and SM group were highly reduced compared to the control group. Creatinine, BUN, ALT, AST levels of PN group and SM group were normal. Conclusion : According to the above results, it is considered that SM is effective treatment for the AD.

Objective: The highly pathogenic avian influenza virus (HPAIV) is a threat to the poultry industry as well as the economy and remains a potential source of pandemic infection in humans. Antiviral genes are considered a potential factor for HPAIV resistance. Therefore, in this study, we investigated gene expression related to cytokine-cytokine receptor interactions by comparing resistant and susceptible Ri chicken lines for avian influenza virus infection. Methods: Ri chickens of resistant (Mx/A; BF2/B21) and susceptible (Mx/G; BF2/B13) lines were selected by genotyping the Mx dynamin like GTPase (Mx) and major histocompatibility complex class I antigen BF2 genes. These chickens were then infected with influenza A virus subtype H5N1, and their lung tissues were collected for RNA sequencing. Results: In total, 972 differentially expressed genes (DEGs) were observed between resistant and susceptible Ri chickens, according to the gene ontology and Kyoto encyclopedia of genes and genomes pathways. In particular, DEGs associated with cytokine-cytokine receptor interactions were most abundant. The expression levels of cytokines (interleukin-1β [IL-1β], IL-6, IL-8, and IL-18), chemokines (C-C Motif chemokine ligand 4 [CCL4] and CCL17), interferons (IFN-γ), and IFN-stimulated genes (Mx1, CCL19, 2'-5'-oligoadenylate synthase-like, and protein kinase R) were higher in H5N1-resistant chickens than in H5N1-susceptible chickens. Conclusion: Resistant chickens show stronger immune responses and antiviral activity (cytokines, chemokines, and IFN-stimulated genes) than those of susceptible chickens against HPAIV infection.

큰잎모자반에 함유되어 있는 다당류를 저분자화하기 위해 알긴산 분해 효소를 생산하는 Shewanella oneidensis PKA 1008의 조효소액을 첨가하여 저분자화하고 이의 면역증진능을 확인하였다. 먼저 저분자화됨을 확인하기 위하여 TLC를 실시한 결과 분해 24 h 이후부터 분해되기 시작하여 최종 60 h에서 dimers로 분해되었다. 그 후 비장세포에 큰잎모자반의 효소적 추출 분해물을 처리하여 in vitro에서 면역증진능을 확인한 결과 $IFN-{\gamma}$, IL-2, IL-6, IL-10의 경우 분해가 진행될수록 분비량이 많아졌다. 또한, 큰잎모자반의 효소적 추출 분해물을 2주 동안 마우스에 경구투여 한 결과, MTT assay 및 비장세포에서 분비되는 $IFN-{\gamma}$ 및 IL-2의 분비량의 경우 24 h 처리구에서 대조군보다 높은 수치로 농도 의존적으로 증가함을 나타내었다. IgG2a 분비량의 경우 24 h와 48 h 처리구에서 다소 증가하였으며, NK 세포의 경우 24 h 처리구에서 농도 의존적으로 활성이 증가하여 면역력을 증진시키는 결과를 보여주고 있다. 전혈을 이용하여 일반혈액검사의 경우 24 h 및 48 h 처리군에서 대조군보다 높은 수치를 나타내었다. 이상의 결과를 종합해볼 때 S. oneidensis PKA 1008 유래 조효소에 의한 큰잎모자반 효소적 추출 분해물이 면역 관련 세포증식률을 증가시키고 이에 따른 사이토카인의 분비량을 증가시키며 혈액 내 다양한 면역세포들의 수치를 증가시킴으로써 면역증진능에 탁월한 효과를 나타냄을 확인하였으나, 면역증진 효과에 기여하는 활성물질에 대해서는 밝혀지지 않아 그에 대한 추가적인 연구가 요구된다.

Background: Red-fleshed sweet orange juice (ROJ) comes from a new variety of citrus cultivated in Brazil that contains high levels of ${\beta}$-carotene and lycopene, and similar amounts of hesperidin (HSP) and nutrients, equivalently to blond orange juice (BOJ). Such bioactive compounds are associated with chemopreventive actions in several cancer cell lines. The purpose of this study was to examine the cytotoxicity, cell cycle, apoptosis, and cytokine secretion after BOJ, ROJ, and HSP treatment of a novel T acute lymphoblastic leukemia cell line, Loucy. Materials and Methods: Loucy cells were incubated for 24-h with BOJ, ROJ, and HSP, and the viability was measured using trypan blue. Cell cycling and apoptosis were assessed by propidium iodide (PI) and annexin V-FITC/PI flow cytometry, respectively. Secretion of cytokines $IL-1{\alpha}$, $IL1-{\beta}$, IL-2, IL-4, IL-6, IL-10, IL-17A, $IFN{\gamma}$, $TNF{\alpha}$, $TGF{\beta}$, $MIP{\alpha}$, and $MIP{\beta}$ was determined by ELISA array. Results: BOJ and ROJ treatments promoted Loucy cell cytotoxicity. Additionally, BOJ induced cell cycle arrest in the G0/G1 phase, and decreased the cell accumulation in the G2/M. ROJ decreased only the G0/G1 fraction, while HSP did not change the cell cycle. BOJ led to apoptosis in a different fashion of ROJ, while the first treatment induced apoptosis by increase of late apoptosis and primary necrotic fractions, the second increased early and late apoptosis, and primary necrotic fraction compared to positive controls. HSP had no effect on apoptosis. IL-6 and IL-10 were abrogated by all treatments. Conclusions: Taking together, these results suggest potential chemopreventive effects of BOJ and ROJ on Loucy cells.

The protective effect of the Synadenium carinatum latex lectin (ScLL), and the possibility of using it as an adjuvant in murine model of vaccination against American cutaneous leishmaniasis, were evaluated. BALB/c mice were immunized with the lectin ScLL (10, 50, 100$[\mu}g$/animal) separately or in association with the soluble Leishmania amazonensis antigen (SLA). After a challenge infection with $10^6$ promastigotes, the injury progression was monitored weekly by measuring the footpad swelling for 10 weeks. ScLL appeared to be capable of conferring partial protection to the animals, being most evident when ScLL was used in concentrations of 50 and 100${\mu}g$/animal. Also the parasite load in the interior of macrophages showed significant reduction (61.7%) when compared to the control group. With regard to the cellular response, ScLL 50 and 100 ${\mu}g$/animal stimulated the delayed-type hypersensitivity (DTH) reaction significantly (P < 0.05) higher than SLA or SLA plus ScLL 10 weeks after the challenge infection. The detection of high levels of IgG2a and the expression of mRNA cytokines, such as IFN-$\gamma$, IL-12, and TNF-$\alpha$ (Th1 profiles), corroborated the protective role of this lectin against cutaneous leishmaniasis. This is the first report of the ScLL effect on leishmaniasis and shows a promising role for ScLL to be explored in other experimental models for treatment of leishmaniasis.

An understanding of the nature of the immune response to asexual erythrocytic stages of malaria parasites will facilitate vaccine development by identifying which responses the vaccine should preferentially induce. The present study examined and compared the immune responses of NIH mice in either single or mixed infections with avirulent (DK) or virulent (DS) strains of Plasmodium chabaudi adami using the ELISA test for detecting and measurement of cytokines and antibody production. In both single and mixed infections, the study showed that both cell- and antibody-mediated responses were activated. In all experiments, an early relatively high level of IFN-$\gamma$ and IgG2a during the acute phase of the infection, and later elevation of IL-4 and IgG1, suggested that there was a sequential Th1/Th2 response. However, in the avirulent DK strain infection a stronger Th1 response was observed compared to the virulent DS strain-infection or in mixed infections. In the virulent DS infection, there was a stronger Th2 response compared to that in the DK and mixed infections. The faster proliferation rate of the virulent DS strain compared to the DK strain was also evident.
