Recently Atopic Dermatitis(AD) is increasing along with allergic disease. At present, there is no infallible cure for AD. Then AD patients undergo great suffering. This study is carried out to see whether or not the administering Danggwieumja(DG) along with Samhwangseje-gamibang(SG} as a medicine for external aplication, is effective in treating atopic dermatitis. To examine the effectiveness of the above prescription, the author made an observation of diverse immune responses. through the model of NC/Nga atopic mice. Results provided evidence that the DG administration along with SG can be used as a treatment means to atopic dermatitis. The results are as follows: The extent of Clinical skin severities in 13 and 16 week old NC/Nga mice treated with DG and SG, were reduced by 50.9%, 53.9% respectively, compared to the control NC/Nga mice with no drug treatment. IgE, IL-4, IL-5, IL-6, IgM and IgG1 levels in the serum of the NC/Nga mice treated with DG and SG were significantly decreased compared to those of the untreated control mice. In contrary, to the $IFN-{\gamma}$ level, significantly increased. The spleen weight of the NC/Nga mice treated with DG and SG significantly decreased compared to those of the untreated control mice. CCR3 gene expression in the skin tissue of NC/Nga mice treated with DG and SG were highly decreased, and the IL-6 expression significantly decreased, and the $IFN-{\gamma}$ gene expression increased compared to those of the untreated control mice. Histological observation of the ear and dorsal skin tissue of the NC/Nga mice treated with DG and SG, showed that the extents of inflammation and infiltrated immune cells in the epidermal tissue and dermis, were highly reduced compared to those of the untreated control mice. In the model inducing COX-2 activity in RAW 264.7 cell, the denser DG became, the more COX-2 activity was inhibited, compared to those of the untreated control group. $IL-1{\beta}$, and $TNF-{\alpha}$, IL-6 gene expression in RAW 264.7 cell with DG, significantly decreased, compared to those of the untreated control group. According to the assessment of cell toxicity in L929 cell, the rate of cell multiplication increased by 3% in consistency to 100ppm of DG compared to the untreated control group and in more than the 200 ppm consistency, cell toxicity was occurred.

Our previous study for developing seeds of Iksan 526 (I.526), an inbred line of resveratrol-producing transgenic rice line, showed that, in 20 days after heading (DAH) seeds, resveratrol was almost saturated and accumulation of piceid was highest though the expression of Arachis hypogaea resveratrol synthase 3 (AhRS3, GenBank DQ124938) was highest in 31 DAH seeds. In this study, it was investigated how the overexpression of AhRS3 affects phenylpropanoid pathway genes. p-Coumaroyl-CoA is derived from phenylpropanoid pathway and used as a substrate of AhRS3 reaction for resveratrol production. In 6, 13, 20, 31 and 41 (45 for Dongjin) DAH seeds of I526 and Dongjin, a wild type of I.526, respectively, the expression pattern of phenylpropanoid pathway genes, including phenylalanine ammonia-lyase (PAL: LOC_Os02g41630.2, LOC_Os04g43760.1), cinnamate 4-hydroxylase (C4H: LOC_Os05g25640.1), 4-coumarate-CoA ligase (4CL: LOC_Os02g08100.1), cinnamoyl-CoA reductase (CCR: LOC_ Os09g25150.1, LOC_Os08g34280.1), hydroxycinnamoyl-CoA shikimate/quinate hydroxycinnamoyl transferase (HCT: LOC_Os04g42250.2, LOC_Os02g39850.1) and cinnamyl alcohol dehydrogenase (CAD: LOC_Os02g09490.1), was examined using real time (RT)-PCR. Compared to developing seeds of Dongjin, RT-PCR results showed that the expression pattern of phenylpropanoid pathway genes was modified in developing seeds of I.526. In most genes, except for CAD, of I.526 developing seeds, the gene expression was highest in 20 DAH corresponding to biosynthesis of resveratrol and piceid, i.e. the expression of phenylpropanoid pathway genes was gradually increased by 20 DAH and decreased as seeds develop. Especially, in Dongjin, the highest expression of PALs and 4CL was in 6 DAH and their expression was gradually decreased as seeds develop. These genes expression data also exhibited that, in developing seeds of I.526, phenylpropanoid pathway genes were slightly or significantly (in some genes) upregulated compared to Dongjin. Therefore, the overexpression of AhRS3 changed the expression pattern of phenylpropanoid pathway genes in I.526 developing seeds and this modification for gene expression is closely related to biosynthesis of resveratrol and piceid.

Background : Recently, so many people are suffered from the allergic or auto-immune disease, and the representative disease is just Allergic Asthma. It is because human immune function has been decreased. Many treatments were done to treat this disease, and many methods were studied to increase immune function and to suppress the asthma. But, the effect of asthma-suppression and improvement of immune response of EH-HA(Ephedrae Herba Herbal Acupuncture) has not been studied in detail. To study the effects of EH-HA, we injected EH-HA at Joksamni(ST36) of C57BL/6 mice. Objectives : The purpose of this study is to investigate the effect of asthma-suppression and improvement of immune response of EH-HA(Ephedrae Herba Herbal Acupuncture). EH-HA was done at Joksamni(ST36) of the mice with ovalbumin-induced asthma. Methods : C57BL/6 mice were sensitized and challenged with OVA(ovalbumin) for 12 weeks. Two experimental groups were treated with different concentrations(1%, 0.1%) of EH-HA at Joksamni(ST36) for the later 8 weeks(3times/week). Results : 1. The lung weight of the group treated with EH-HA decreased significantly compared with that of control group. 2. The total cells in lung, total leukocytes and eosinophils in BALF of the group treated with EH-HA decreased significantly compared with those of control group. 3. Eosinophils in BALF of the group treated with EH-HA in photomicrographs decreased significantly compared with those of control group. 4. The concentrations of IL-13, IgE, IL-4 in serum and IL-4 in BALF of the group treated with EH-HA decreased significantly compared with those of control group. 5. The numbers of $Gr-1^+/CD11b^+\;cells,\;CD3e^-/CCR3^+\;cells,\;CD4^+\;cells,\;CD8^+\;cells,\;CD3e^+/CD69^+\;cells\;and\;IgE^+/B220^+\;cells$ in lung of the group treated with EH-HA decreased significantly compared with those of control group. 6. In RT-PCR, the mRNA expression of IL-4, IL-5 and IL-13 in the group treated with EH-HA decreased compared with those of control group. Conclusion : These results suggested that EH-HA at Joksamni(ST36) in C57BL/6mice may be effective to OVA-induced asthma of C57BL/6 mice.

The present study examined the effects of Taekunyukmijiwhang-tang (TV) on blood pressure and renal function in nitric oxide (NO)-dependent hypertensive rats. A phamacological inhibition of nitric oxide synthase (NOS) for 4-6 weeks produces renal vasoconstriction, renal dysfunction, and progressive severe hypertension. Treatment of rats with NG-Nitro-L-arginie methylester (L-NAME) (100 mg/L, 6 weeks), which is a nonspecific NOS inhibitor, cause a sustained increase in systolic blood pressure (SBP), along with the decrease in expression of ecNOS in the kidney and thoracic aorta. The expression of Na, K-ATPase α1 subunit in the kidney was also reduced in the L-NAME induced hypertensive rats group. The renal functional parameters including urine osmolality (Uosm), creatinine clearance (Ccr), which is an index of glomerular filtration (GFR) were decreased in rat with L-NAME induced hypertension. while solute-free water reabsoption (TcH₂O) was unchanged in all experimental group. However, the group combined treated with TV and L-NAME did not develop hypertension and expression of ecNOS in the aorta was restored. The expression of Na/sup +/, K/sup +/-ATpase α1 subunit in the kidney was markedly restored in L-NAME-induced hypertension rats by administration of TV along with the restoration of urinary volume (UV) and sodium excretion (UNaV), whlie Na/sup +/, K/sup +/-ATPase /β1 subunit was not altered. These results suggest that TV attenuates an increase in SSP in the L-NAME induced hypertension and restores partially renal function, which seems to be caused by up-regulation of expression of Na/sup +/, K/sup +/-ATPase α1 subunit in the kidney and ecNOS in thoracic aorta.

Background: Dendritic cell (DC)-based vaccines are currently being evaluated as a novel strategy for tumor vaccination and immunotherapy. However, inducing long-term regression in established tumor-implanted mice is difficult. Here, we show that deoxypohophyllotoxin (DPT) induces maturation and activation of bone marrow-derived DCs via Toll-like receptor (TLR) 4 activation of MAPK and NF-${\kappa}B$. Methods: The phenotypic and functional maturation of DPT-treated DCs was assessed by flow cytometric analysis and cytokine production, respectively. DPT-treated DCs was also used for mixed leukocyte reaction to evaluate T cell-priming capacity and for tumor regression against melanoma. Results: DPT promoted the activation of $CD8^+$ T cells and the Th1 immune response by inducing IL-12 production in DCs. In a B16F10 melanoma-implanted mouse model, we demonstrated that DPT-treated DCs (DPT-DCs) enhance immune priming and regression of an established tumor in vivo. Furthermore, migration of DPT-DCs to the draining lymph nodes was induced via CCR7 upregulation. Mice that received DPT-DCs displayed enhanced antitumor therapeutic efficacy, which was associated with increased IFN-${\gamma}$ production and induction of cytotoxic T lymphocyte activity. Conclusion: These findings strongly suggest that the adjuvant effect of DPT in DC vaccination is associated with the polarization of T effector cells toward a Th1 phenotype and provides a potential therapeutic antitumor immunity.

The purpose of this paper is to investigate various factors affecting the efficiency of China IC industry, reflecting the resource utilization and overall development level of China IC industry. In this paper, three input indicators (R&D Expenditure, Cash paid to and for employees, Total fixed assets) and two output indicators (Net profit, Sales revenue) were selected for 17 listed companies in the IC industry with operating profit of less than 1 billion yuan in 2018 and applied the technology efficiency theory and DEA analysis method to analyze the relative efficiency of the output base. The study found that one of the 17 companies analyzed was efficient, two were inefficient on an inadequate scale, and the rest were inefficient due to insufficient production technology, scale and management level. This study argues that enterprises should reduce resource input appropriately and strengthen scientific and technological innovation management to maximize resource utilization efficiency. Therefore, this study has important practical significance for improving the efficiency of IC enterprises. The Malmquist method will be used to study the total factor productivity of small and Medium-sized companies in IC industry.

Renal ischemia-reperfusion injury(IRI), an important cause of acute renal failure (ARF), cause increased renal tubular injury. Jesaeng-sinkihwan (JSH) was recorded in a traditional Chines medical book named "Bangyakhappyeon (方藥合編)". JSH has been used for treatment of diabetes and glomerulonephritis with patients. Here we investigate the effects of Jesaeng-sinkihwan (JSH) in a mouse model of ischemic acute kidney injury. The animals model were divided into four groups at the age of 8 weeks; sham group: C57BL6 male mice (n=9), I/R group: C57BL6 male mice with I/R surgery (n=9), JSH Low group: C57BL6 male mice with surgery + JSH 100 mg/kg/day (n=9) and JSH High group: C57BL6 male mice with surgery + JSH 300 mg/kg/day (n=9). Ischemia was induced by clamping the both renal arteries during 25 min, and reperfusion was followed. Mouse were orally given with JSH (100 and 300 mg/kg/day during 3 days after surgery. Treatment with JSH significantly ameliorates creatinine clearance(Ccr), Creatinine (Cr) and blood urea nitrogen(BUN) in obtained plasma. . Treatment with JSH reduced kidney inflammation markers such as Neutrophil Gelatinase Associated Lipocalin (NGAL) and kidney injury molecule-1 (KIM-1). JSH also reduced the periodic acid schiff (PAS) staining intensity and picro sirius red staining intensity in kidney of I/R group. These findings suggest that JSH ameliorates tubular injury including renal dysfunction in I/R induced ARF mouse.

Ureteral obstruction can be causes of renal dysfunction and renal injury at late period of kidney pathology. The purpose of this study was to determine the protective effects of Oryeongsan (ORS), Geumgwe-sinkihwan (GSH), and Jwagwieum (JGE) in rats with unilateral ureteral obstruction (UUO). The animal models were divided into five groups randomly at the age of 5 weeks; Control group: SD male rats (n=10), UUO group: SD male rats with UUO surgery (n=10), ORS group: SD male rats with UUO surgery + ORS 200 mg/kg/day (n=10), GSH group: SD male rats with UUO surgery + GSH 200 mg/kg/day (n=10), JGE group: SD male rats with UUO surgery + JGE 200 mg/kg/day (n=10). Treatment with ORS, GSH, and JGE significantly ameliorate creatinine clearance(Ccr). The present results also showed that ORS, GSH, and JGE improved the morphological aspects of renal tissues. These prescriptions also reduced the expression levels of cytokines such as TNF-α, IL-1β, and IL-6. In Kidney, UUO increased the expression levels of inflamasome markers such as NLRP3, ASC, and Caspase-1. However, ORS, GSH, and JGE suppressed these levele. Treatment with these prescriptions reduced kidney inflammation markers such as Neutrophil Gelatinase Associated Lipocalin (NGAL) and kidney injury molecule -1 (KIM-1). Therefore, these findings suggest that ORS, GSH, and JGE has a protective effect on renal injury by alleviating renal inflammation and improving renal function in rats with UUO.
