Objectives The purpose of this study is to investigate the effect of SPDJTK(SoPungDoJeokTangKami) and concurrent administration of AJ(Atopy cream, Jawoongo)+SPDJTK on atopic dermatitis-like skin lesions by using in NC/Nga atopic dermatitis mouse induced by BMAC-induced mice. Methods Clinical skin score, hematology and Serum total IgE and IgG1 of NC/Nga atopic dermatitis mice were evaluated. Moreover, the cytokine level, total cell number, Immunohistochemical staining and Histological features of axillary lymph node(ALN), draining lymph node(DLN), peripheral blood mononuclear cells(PBMCs) and dorsal skin tissue were used in NC/Nga mice. Results Orally administrated SPDJTK with concurrent administration of SPDJTK and AJ decreased the clinical skin score, total cell number of WBC, eosinophils in blood, serum total IgE & IgG1, IL-5, IL-13, IFN-$\gamma$. Also, total cell number of ALN and dorsal skin tissue, absolute cell number of CD4+, CD8+, CD3+CD69+, CD3+CCR3+, CCR3+, CD4+CXCR5+ in ALN, absolute cell number of CD3+CCR3+, CCR3+ in DLN, granulocytes in PBMCs, activation cell number of CD3+CD69+, CCR3+, total cell number of CD3+ T cell in dorsal skin tissue were significantly decreased. Furthermore, thickness of epidermis, infiltrated inflammatory immune cell and mast cell in dermis, amount of Eotaxin2 mRNA, CCR3 mRNA in dorsal skin tissue, gene expression of IL-5, IL-13 mRNA in ALN, CD4+ Th cell in dorsal skin tissue and CCR3+ eosinophils in ALN were all significantly decreased. However, total number of DLN, absolute number of CD3e+ T cell and CD19+ B cell, absolute number of CD4+, number of Th cell in DLN and gene expression of foxp3 mRNA were significantly increased significantly. Conclusions Concurrent administration of SPDJTK and AJ on atopic dermatitis in NC/Nga atopic dermatitis mouse was very effective treatment for atopic dermatitis.

Haepyoijin-tang and its main components have been used for phlegm, cough and dyspnea. Using a respiratory inflammation model, we intend to reveal the anti-inflammatory effect and pharmacological mechanism of Haepyoijin-tang. We induced the respiratory inflammation model by Aspergillus oryzae protease and ovalbumin administration. Female Balb/c mice (8 weeks old) were classified into four groups as follows: saline control group, aspergillus oryzae protease and ovalbumin induced respiratory inflammation group (vehicle), inflammation with Haepyoijin-tang (200 mg/kg) administration group, inflammation with dexamethasone (5 mg/kg) administration group (n=7). To identify the anti-inflammatory effects of Haepyoijin-tang water extracts, we measured the inflammatory cell number in bronchoalveolar lavage fluid (BALF) and total live lung cell number. In addition, we checked eosinophil ratio and number in BALF. And Interleukin (IL)-5 level was also measured in lung cell culture supernatant. To confirm the mechanism of anti-inflammatory effects, we analyzed the activated helper T cell (CD4⁺CD25⁺ cell) and Th2 cell (CD4⁺GATA3⁺ cell) ratio and number in lung by using flow cytometry. Finally, we attempted to confirm the immune mechanism by measuring the ratio and number of regulatory T cells (CD4⁺Foxp3⁺ cell). Haepyoijin-tang extracts treatment diminished inflammatory cell, especially, eosinophil number in BALF and total live lung cell number. Moreover, IL-5 level was reduced in Haepyoijin-tang treated group. Surprisingly, Haepyoijin-tang extracts administration not only decreased the activated helper T cell but also Th2 cell population in lung. Additionally, regulatory T cell population was increased in Haepyoijin-tang administration group. Our findings proved that Haepyoijin-tang extract have anti-inflammatory efficacy by suppressing Th2 cell activation and promoting regulatory T cell population.

This study was conducted to investigate the effect of various addition and exclusion time of glucose (Control: no addition, A: 24～72 h, B: 24～48 h, C: 48～72 h, D: 0～72 h, E: 0～48 h, F: 0～24 h and 48～72 h, G: 0～24 h) on embryonic developmental capacity of 2-cell embryos in mice. Developed blastocysts were assessed for mean cell number by differential staining. The zona-intact blastocyst (ZiB) rates were higher (p<0.05) in group B than control. However, the zona-escape blastocyst (ZeB) rates were not significantly different in all groups. At 72 h, total blastocyst (ZiB + ZeB) formation rates were not significantly different in all groups. The mean cell number was not significantly different among all groups. The inner cell mass (ICM) cell number was higher (p<0.05) in group F than control, group A, B and G. The trophectoderm (TE) cell number was higher (p<0.05) in control than group A and D. The %ICM was higher (p<0.05) in group C, D and F than control. The ICM : TE ratio was not significantly different in all groups. Between control and glucose group, no significant difference was observed in the total blastocysts (ZiB + ZeB) formation rates. Also, no significant difference was observed in the mean cell number, ICM cell number and ICM : TE ratio. However the TE cell number was higher (p<0.05) in control than glucose group and %ICM was higher (p<0.05) in glucose group than control. In conclusion, glucose added in culture medium was not inhibitory on blastocyst formation but glucose added for 48 ～72 h in culture medium increases %ICM of blastocysts in mice.

Histological changes was investigated in the 4 weeks old rat brain using NMDA (N-methyl-D-asparate) which is capable of mediating excitotoxic events. The changes were occured when the injected NMDA solved in PBS was over $1.0{\mu}g/g$(about 90nM). The necrosis of Purkinje cells in cerebellum and the increasement of coloidal plexus cell number were prevalent. The Purkinje cell number of necrosis were increased according to increasement of amount of injected NMDA. In spite of increasement of degenerated Purkinje cell number, differentiation of new Purkinje cell was not identified because total number of Purkinje cell was not changed. The change of cell number was observed in coloidal plexus cell rather than degeneration of cell. About 5 time increasement was occured. This change may cause increasement of cerebrospinal fluid and the makes mophorogy of brain more round than nomal.

The aim of this study was to improve efficiency and quality of the production of Korean Native Cow embryos. We examined effects of ovarian morphology and maturation vessel on the development and cell number of blastocysts. The development rates to the 2-cell embryos from oocytes collected from the ovaries of different morphological statues were similar ranging between 70.3 and 84.1%. The development rate to the 8 cell- and blastocyst-stage embryos was the highest in the group without both corpus luteum (CL) and follicle. The inner cell mass (ICM), trophectoderm (TE) and total cell number (TCN) were significantly higher in the groups of follicular cyst and regressive CL than other treatment groups, and the same pattern was observed in the ICM/TCN ratio. The development rate to the 2-cell stage was significantly higher in 0.5-㎖ straw group than 0.25-㎖ straw group. However, the development rates to the blastocyst stage were similar between the dish and the straw group. There were no differences in the number of ICM and TE cells, TCN and ICM/TCN ratio of blastocysts from oocytes matured in the different vessels.

The purpose of this study was to investigate the development of bovine nuclear transfer (NT) embryos cultured in serum-free conditions. Bovine NT embryos cultured in various culture conditions were compared blastocyst development, total cell number and apoptosis using TUNEL assay. In experiment 1, blastocyst rates of NT embryos were significantly higher (P<0.01) in FBS (22.0％) and BSA (26.6％) groups than in PVA (6.3％) group. Total cell number was significantly higher in FBS (78.4$\pm$19.4) and BSA (90.9$\pm$29.1) groups than in PVA group (46.0$\pm$0.0). Apoptotic cell number was significantly fewer in FBS (3.1$\pm$1.4) and BSA (1.7$\pm$1.4) groups than in PVA group (7.0$\pm$20.0) However, all of results were not different between the FBS and BSA group. In experiment 2, blastocyst rates of NT embryos were significantly higher (P<0.05) in fatty acid free-BSA (FAF-BSA) group (26.8％) than in fraction V-BSA group (11.2％). Total cell number were somewhat higher in FAF-BSA group (89.8$\pm$30.7) than in fraction V-BSA group (88.1$\pm$19.3). Apoptotic cell number were somewhat fewer in FAF-BSA (1.7$\pm$1.5) group than in fraction V-BSA group (4.2$\pm$2.9). These findings suggest that serum free condition were effective for the in vitro development of bovine NT embryos. Therefore, we concluded that fatty acid free-BSA has beneficial effect in development bovine NT embryos and can be use as a serum substitute.
