Hot environments can affect feed intake and lactation, and the subsequent unavailability of important micronutrients to the newborn piglet can impair piglet growth, reduce the viability of newborn piglets and limit their subsequent performance. This work addresses the effects of hot environments (summer season) upon the reproductive performance of sows during gestation and lactation as well as on the serum levels of vitamins and the concentration of immunoglobulins in their litters in comparison with the winter season. Fourteen sows were evaluated over 100 ± 2 days of gestation in each season. The temperature and humidity index (THI) was used as an indirect measure of heat stress during gestation. The reproductive performance, milk yield, and body condition of the sows were recorded. The concentrations of vitamin E and vitamin A in piglets and in sow serum, colostrum, milk and feed were determined by HPLC; immunoglobulins were assessed by an ELISA. The THI index indicated that animals were subject to heat stress only in during the summer. Although the effect was not significant, there were a lower number of piglets at birth and at weaning and the milk yield in summer compared with winter. There was no difference (p > 0.05) in the body condition of sows between seasons. Season had an effect (p < 0.05) on the vitamin A concentration of postpartum sow serum (0.29 ㎍/mL in winter vs 0.21 ㎍/mL in summer) and on the vitamin E concentration before birth (2.00 ㎍/mL in winter vs 0.90 ㎍/mL in summer). Vitamin E in milk was higher (p < 0.05) in winter than in summer (2.23 vs 1.81 ㎍/mL). Serum levels of vitamins A and E in piglets at birth were lower (p < 0.05) in winter than in summer. The concentrations of immunoglobulins (IgG and IgA) in colostrum and milk were similar between seasons (p > 0.05), but the IgA in piglet serum was higher in winter than in summer (p < 0.05). High temperatures produced heat stress in sows, which affected certain aspects of production that can be translated into economic losses for this sector.

Objective : Membranous nephropathy (MN) is the most common cause of adult nephrotic syndrome worldwide. MN has been defined as granular subepithelial deposition of IgG immune complexes along the glomerular basement membrane (GBM). We aimed to identify the effects of Chungyeolmaksungbang (CYMSB) treatment on cBSA-induced in MN mouse model. Methods : The effect of Chungyeolmaksungbang treatment was studied on the morphology and protein excretion in the cationized bovine serum albumin (cBSA)induced mouse chronic serum sickness nephritis model. One group of mice was given intra-peritoneal (i.p.) immunizing doses of cBSA and complete Freund's adjuvant. One week later, these animals began a single i.p. injection of cBSA for 4 weeks. A second group followed the same injection protocol, but was given CYMSB p.o. Results : Proteinuria significantly was decreased and serum albumin was increased in the group treated with cBSA and CYMSB extract compared with the control. Serum BUN was significantly decreased on CYMSB compared with control. CD3e+/CD19 cells ratio of peripheral blood was decreased and CD4+/CD8 cells was increased. Level of $IL-1{\beta}$ was significantly decreased, and $IFN-{\gamma}$ was significantly increased. Concentration of IgG and IgM was significantly decreased compared with control. Thickness of GBM was decreased on histological analysis of kidney. Deposition of CD4 and CD8 was decreased on immunohistochemical staining of kidney. Conclusions : We conclude that CYMSB treatment may could be a useful remedy agents for treating the MN with cBSA.

A rise in the occurrence of allergic diseases is attributed to the dysregulated balance of type 1/type 2 immunity, where type 2 T-helper (Th2) cells predominate over type 1 T-helper (Th1) cells, leading to an abnormally increased production of IgE in response to unharmful antigens. Kimchi, a traditional Korean fermented food, is a rich source of beneficial lactic acid bacteria. In this study, we investigated the ability of Enterococcus faecium FC-K derived from kimchi to induce type I immunity in the presence of Th2 polarizing conditions in vitro and in vivo. Stimulation of mouse peritoneal macrophages with E. faecium FC-K induced the production of tumor necrosis factor alpha, interleukin (IL)-6, and IL-12. Under the in vitro Th2 conditions in which splenic T cells were activated in the presence of IL-4, E. faecium FC-K enhanced the ability of T cells to produce interferon $(IFN)-{\gamma}$. Using the ovalbumin (OVA)-induced allergy model, male BALB/c mice receiving E. faecium FC-K reduced the serum level of total IgE, but not that of OVA-specific IgE. Furthermore, the population of activated splenic B cells during OVA immunization was decreased in E. faecium FC-K-treated mice, accounting for a reduction of total IgE in the serum. Restimulating splenocytes from OVA-immunized mice with OVA ex vivo resulted in an increased production of $IFN-{\gamma}$, with no effect on IL-4, in E. faecium FC-K-treated mice. These observations provide the evidence that E. faecium FC-K can be a beneficial probiotic strain that can modulate the Th2-mediated pathologic response.

Purpose : The objective of present study is to detect the effect of Sopungsan aqueous extracts (SPS) on the passive cutaneous anaphylaxis (PCA; type I allergic dermatitis) Method : 500, 250 and 125mg/kg of SPS were orally administered 12 hr-interval before antigen challenge (total 4 times administered). PCA reactions were induced using rat anti-ovalbumin (OVA) serum contain IgE (titer 1:32) as sensitization and OVA as antigen challenge. 30 min after antigen challenge, the diameter of blue-dye spots (evans blue) and leaked amount of dye were observed with histology and histomorphometry at the PCA induced sites. In addition, serum total IgE and histamine levels were also observed by ELISA, respectively. The effects of SPS were compared with dexamethasone 1mg/kg treated rats in the present study. Results : As results of PCA reaction, vasodilation related increase of diameter of blue-dye spot and amount of leaked dye were observed with swelling and edematous changes in the dermis of PCA induced sites. However, these changes on PCA reactions were dramatically and dose-dependently decreased by treatment of SPS as compared with vehicle control. In addition, serum elevations of IgE and histamine were also dose-dependently inhibited by treatment of SPS as compared with vehicle control respectively. The effects of SPS 500mg/kg were similar to that of dexamethasone 1mg/kg in the present study. Conclusion : Base on the results of the present study, it is concluded that SPS has favorable effect on the PCA-induced allergic dermatitis, and SPS 500mg/kg showed similar favorable effects as compared with dexamethasone 1mg/kg. The present findings demonstrate that SPS can be effective for the prevention and treatment of allergic dermatitis.

Objectives : This experimental study was performed to prove the effect of Ikryung-Tang (yiling-tang; IRT) and Ikryung-tangkamibang (yiling-tangjiaweifang; IRT I, IRT II) on rats with nephrosis induced by a single intravenous injection of puromycin aminonucleoside (PAN). Methods : The effects of IRT, IRT I and IRT II on PAN nephrosis were evaluated by measuring the gene expression of IL-4, $IFN-{\gamma}$ and the concentrations of IgE, albumin, total protein, cholesterol, triglyceride, creatinine, and BUN in the serum and the volume & amount of protein of the 24hrs' urine. Results : In the gene expression linked T cell specialization, IRT II inhibited IL-4 and IgE but IRT and IRT I showed no significant difference compared with control group. On the other hand, IRT, IRT I and IRT II increased $IFN-{\gamma}$ compared with the control group. In the urine protein, serum albumin, total protein, BUN, and creatinine, IRT I especially showed more. significant effect than other groups. In the serum cholesterol and triglyceride, IRT II especially showed more significant effect than other groups. In the urine volume during 24 hrs, IRT especially showed more significant effect than other groups. Conclusions : According to the above results, it is suggested that IRT is effective for the treatment of edema, IRT I is effective for the treatment of hypoproteinemia and kidney dysfunction, IRT II is effective for immune modulation and the treatment of cholesteremia. Therefore IRT, IRT I and IRT II seem to be available for treating nephrosis in clinical practice.

Background: This study was performed to determine the effects of liposome-encapsulated bee venom (BV) treatment of inflammatory factors in atopic dermatitis (AD) compared with BV treatment. Methods: AD was induced by phthalic anhydride in mice and the effects of BV liposomes were measured. Using Leica Application Suite, thickened epidermis and dermis were measured after BV liposome treatment (0.05 and 0.1 ㎍/mL). The number of stained mast cells and the concentration of immunoglobulin (Ig)E were measured. Serum IgE concentration was analyzed using an enzyme-linked immunosorbent assay. The serum concentrations of interleukin (IL)-1, IL-4, and IL-6 inflammatory cytokines were measured. The levels of messenger ribonucleic acid expression of proinflammatory cytokines and chemokines were measured using reverse transcription polymerase chain reaction. Inhibition of mitogen-activated protein kinase activation, was analyzed on western blot. To measure the transcriptional activity (NF-κB inhibition by BV liposomes), western blots (p65, p-IκB, p50, and IκB) were also performed. Results: The weight of lymph nodes, serum IgE concentrations, morphological changes in the skins from the backs of the mice, and mast cell numbers in inflamed tissues were noticeably lower in the BV liposome treatment group compared with the BV treatment group. The concentrations of pro-inflammatory cytokines (IL-1, IL-4, IL-6) and chemokines (TSLP, CCL22) were also reduced. Activation of mitogen-activated protein kinase (p-ERK and p-p38), and transcriptional activity (p65, p-IκB, p50, and IκB) was strongly suppressed in the BV liposome group. Conclusion: BV liposomes may have a better therapeutic effect than BV for the treatment of AD.

Objectives : Gagam-Gongjin-dan (GGD) composited with Cervi parvum Cornu, Corni Fructus, Angelica gigantis Radix, Lycii Fructus, Dioscoreae Rhizoma, Citri Pericarpium, Gastrodiae Rihzoma, Agastachis Herba, Cassiae cortkex, Scutellariae Radix, Schisandrae Fructus has been traditionally used for chronic diseases or weakness after illness in oriental countries. However, little is known about the effects of methanol extract of GGD on immune responses to ovalbumin (OVA) plus alum. Therefore, the purpose of this study was to investigate the effects of GGD on immune responses to ovalbumin plus alum in Balb/c mice. Methods : In this study, the extract of GGD was prepared by extracting with methanol for 7 days. The extract was freeze-dried following filtration through vacuum distillation system. Mice were orally administrated with or without GGD extract of different doses (50-200 mg/kg/day) for 30 days. We examined the effects of GGD extract on the serum levels of total IgE, OVA-specific IgE, IgG1, IgG2a, and CTACK/CCL27 production and CCR10 expression in lymph node cells and body weight change and foot pad swelling responses in ovalbumin treated Balb/c. Results : The oral administration of GGD dose-dependently reduced the serum levels of total IgE, OVA-specific immunoglobulin (IgE, IgG1 and IgG2b) and CTACK/CCL27 production in ovalbumin treated BALB/c mice. The levels of CCR10 expression from lymph node cells of OVA treated mice were markedly suppressed by treatment with GGD in a concentration dependent manner. Furthermore, foot pad swelling responses were also markedly suppressed by GGD. However, body weight were significantly increased dose dependently by GGD treatment. Conclusions : These results suggest that GGD treatment suppresses immune responses to ovalbumin, and these properties may contribute to allergic disease care.

Samyoyongantang (SMY), a herbal medicine, has been used as cure for gangrene. To evaluate anti-inflammatory effect of samyoyongantang, we treated samyoyongantang extract in animal model system induced contact hypersensitivity. Contact hypersensitivity, a local inflammatory response of the skin, was induced by 1% DNCB on the right ear of BALB/c mouse. Samyoyongantang was prepared as water extract and administrated everyday for 2 weeks per oral. A right ear of mouse was potently swelled by 1% of DNCB treatm ent, but a mouse ear thickness was significantly reduced by samyoyongantang after 2 we eks treatment. Samyoyongantang reduced IgG in serum obtained from blood of 1 % DNCB-treated mouse. IgE in serum was not changed by samyoyongantang treatment. From these results, anti-inflammatory effect of samyoyongantang, especially reduction of ear swell ing, might be partly due to reduction of IgG in serum.

Objectives: Galgeunhaegitang-gamibang(GH) and Samhwangseze-gamibang(SG) has been known that they are helpful for treatment of atopic dermititis clinically, but there is no report about the effect of GH and SG. So, author aimed to investigate the effects of GH and SG on atopic dermititis of NC/Nga mice. Methods : NC/Nga mice were divide into three group : normal, control, and experimental group. Atopic dermatitis was induced in the control and experimental group by spreading DNCB. Then GH was orally administered three times in a week for 8 weeks to the experimental group and SG was spreaded two times in a day for 8 weeks to the experimental group, while the control group was given normal saline. We observed changes of clinical skin severity score, serum IgE, IL-4, IL-4, IL-5, IL-6, IgM, IgGl, $IFN-{\gamma}$ and so on. We used one-way ANOVA test statistically(p<0.01). Results : Clinical skin severities of experiment group in 13 and 16weeks were significantly decreased by 48% and 55% compared to the control group. Serum IgE, IL-4, IL-5, IL-6, IgM, IgGl levels of experimental group were singnificantly decreased compared to the control group. Serum $IFN-{\gamma}$ level of the experimental group was significantly increased against control group. mRNA expression levels of IL-4, IL-5, IL-6 and CCR3 in the skin tissues of experimental group were significantly decreased compared to the control group. In contrary, $IFN-{\gamma}$y mRNA expression level were increased compared to the control group. Histological observation of the ear and skin tissues showed that the extents of inflammation and infiltrated immune cells in the epidermis and dermis of experimental group were highly deminished compared to the control group. Judging from that $IL-1{\beta}$, $TNF-{\alpha}$, IL-6 expression of gene, the effects of inflammatory cytokine revelation were significantly decreased compared to the control group. In the model inducing COX-2 activity in RAW 264.7 cell, COX-2 activity was significantly inhibited depending on the density of GH compared to the control serum. According to cell multiplication, examination of cell toxicity showed that GH is safe at the density of 10, 50, 100mg/l and even 1000mg/l. Conclusion : Accordin to the above results, it is considered that GH and SG is effective treatment for the atopic dermatitis.
