Background: Although unique aortic pathology related to bicuspid aortic valve (BAV) has been previously reported, clinical implications of BAV to aortopathy risk have yet to be investigated. We looked for potential differences in matrix protein expressions in the aortic wall in BAV patients. Methods: Aorta specimens were obtained from 31 patients: BAV group (n=27), tricuspid aortic valve (TAV) group (n=4). The BAV group was categorized into three subgroups: left coronary sinus-right coronary sinus (R+L group; n=13, 42%), right coronary sinus-non-coronary sinus (R+N group; n=8, 26%), and anteroposterior (AP group; n=6, 19%). We analyzed the expression of endothelial nitric oxide synthase (eNOS), matrix metalloproteinase (MMP)-9, and tissue inhibitor of matrix metalloproteinase (TIMP)-2. Results: Based on the mean value of the control group, BAV group showed decreased expression of eNOS in 72.7% of patients, increased MMP-9 in 82.3%, and decreased TIMP in 79.2%. There was a higher tendency for aortopathy in the BAV group: eNOS $(BAV:TAV)=53%{\pm}7%:57%{\pm}11%$, MMP-9 $(BAV:TAV)=48%{\pm}10%:38%{\pm}1%$. The AP group showed lower expression of eNOS than the fusion (R+L, R+N) group did; $48%{\pm}5%$ vs. $55%{\pm}7%$ (p=0.081). Conclusion: Not all patients with BAV had expression of aortopathy; however, for patients who had a suspicious form of bicuspid valve, aortic wall biopsy could be valuable to signify the presence of aortopathy.

Objectives There is few Korean medicinal studies about post-operation wound healing despite much effort for minimizing wound or post-op scar. The aim of this study is to evaluate the wound healing effect of Gyejibokryeong-hwan (Guizhifuling-wan, GBH) after skin suture. Methods < In vitro > We observed anti-oxidative and anti-inflammatory effect by using lipopolysaccharide (LPS)-treated RAW 264.7 cells. For anti-oxidation, we mesured the total amount of polyphenol, flavonoid, DPPH scavenging ability, ABTS scavenging ability and the value of ROS production, and for anti-inflammation, we mesured the amount of NO and pro-inflammatory cytokines ($TNF-{\alpha}$, $IL-1{\beta}$, IL-6). < In vivo > Thirty SD rats were divided into five equal groups (n=6, one normal, two controls and two experimentals). All groups except normal group were made a scar (around $1{\times}4cm^2$) in the back by the depth of the fascia and then sutured by a thread and needle. Normal group rats received no treatment at all. Control group rats were fed distilled water, and positive control group rats were percutaneously applied terramycin once in 2 days. GBH 200 group rats were orally medicated GBH 200 mg/kg, and GBH 400 group rats were orally medicated GBH 400 mg/kg per day for two weeks. We analyzed the blood samples (WBC, neutrophil, lymphocyte, monocyte, eosinophil), and the serums (TIMP-1, MMP-2, MMP-2. $PGE_2$, $TGF-{\beta}$, VEGF), and examined the wounded skin tissue histopathologically. Results < in vitro > 1. DPPH and ABTS scavenging activity was increased concentration-dependantly, and ROS production was significantly increased in GBH treated cells ($100{\mu}g/ml$). Therefore in this study, Gyejibokryeong-hwan appears to have the anti-oxidative. 2. NO production was significantly reduced in GBH treated cells ($100{\mu}g/ml$), and $IL-1{\beta}$ production was significantly reduced in GBH treated cells ($1{\mu}g/ml$). But, $TNF-{\alpha}$ and IL-6 did not show uneffective action. Therefore in this study, Gyejibokryeong-hwan did not show any significant effect on anti-inflammatory process. < in vivo > 1. Monocyte and neutrophil was significantly increased in GBH (200, 400) groups. WBC, lymphocyte and eosinophil did not show significant change. 2. TIMP-1, MMP-2, VEGF were significantly increased in GBH 400 group, $PGE_2$ was significantly reduced in GBH 400 group. $TGF-{\beta}$ was significantly increased in GBH (200, 400) groups, and MMP-9 was increased concentration-dependantly in GBH groups, but there was no significance. 3. In histopathological examinations, collagen was significantly increased and keratin was significantly decreased in GBH (200, 400) groups. Conclusions According to in vitro experiment, GBH appears to have the anti-oxidative effect and in vivo experiment, GBH stimulate the wound healing process hematologically and histopathologically. In conclusion, the results suggest that GBH promotes wound healing after skin suture.

Objective : This study was performed to investigate the anti-fibrogenic effect and changes of inflammation-related genes by YBR I and YBR II (YBR I: Arteisiae Capillaris Herba, Atractylodis Rhizoma Alba, Hoelen/ YBR II: YBR I +Sanguisorbae Radix, Biotae Cacumen, Cirsii Japonici Herba) on HSC(hepatic stellate cells)-T6 and TAA-induced rat liver tissue. Materials and Methods : HSC-T6 were treated with various concentrations of distilled-water extract YBR I and YBR II extract for 24, 48 and 72 hours. After the treatment, cell viability, proliferation, procollagen levels and IL-6 levels were measured by using MTT Assay, BrdU Assay, Procollagen Type 1 C-peptide EIA kit, and Murine IL-6 ELISA Development kit. Rat liver fibrosis was induced by intraperitoneal TAA injection of 150mg/kg 3 times a week for 6 weeks. After the treatment, body weight, liver & spleen weights, liver function test, complete blood cell count and change of portal pressure were studied. In addition, gene expressions of ASMA, IL-6, MMP-2, TIMP-1 and TIMP-2, all of which are known to be associated with liver fibrosis, were analyzed by using Real-Time PCR. After YBR I and YBR IItreatment, percentages of collagen in TAA-induced rat liver tissue were measured. Results : The viability and proliferation of the HSC-T6 decreased as the concentration increased. The production of procollagen decreased as the concentration increased. The production of IL-6 was little influenced by YBR I and YBR II. There was no difference in rat body weight between the TAA-only group and the YBR groups. Compared with rat liver weight of TAA-only group, that of the YBR groups increased. In the YBR I group, the serum level of AST elevated by TAA injection significantly decreased and in the YBR I and II group, the serum level of ALP and ALT elevated by TAA injection decreased. In the YBR I group, white blood cell count elevated by TAA injection decreased but platelets increased. In the YBR I group, the portal pressure elevated by TAA injection significantly decreased. Decreases in the gene expression of ASMA and MMP-2 were observed in the YBR I group. The gene expression of IL-6 was little influenced by YBR I and YBR II -treated groups. In the histological finding, TAA injections caused severe fibrosis, but YBR I and YBR II treatment significantly reduced the amounts of hepatic collagens. Conclusions : These results suggest that YBR I and II have inhibitory effects on the hepatic fibrogenesis.

Background: T cell immunoglobulin mucin containing molecule (TIM)-3 is expressed in differentiated Th1 cells and is involved in the suppression of the cytokine production by these cells. However, the regulation of the expression of other T cell genes by TIM-3 is unclear. Herein, we attempted to identify differentially expressed genes in cells abundantly expressing TIM-3 compared to cells with low expression of TIM-3. Methods: TIM-3 overexpressing cell clones were established by transfection of Jurkat T cells with TIM-3 expression vector. For screening of differentially expressed genes, gene fishing technology based on reverse transcription-polymerase chain reaction (RT-PCR) using an annealing control primer system was used. The selected candidate genes were validated by semi quantitative and real-time RT-PCR. Results: The transcription of TIMP-1, IFITM1, PAR3 and CCL1 was different between TIM-3 overexpressing cells and control cells. However, only CCL1 transcription was significantly different in cells transiently transfected with TIM3 expression vector compared with control cells. CCL1 transcription was increased in primary human $CD4^+$ T cells abundantly expressing TIM-3 but not in cells with low expression of TIM-3. Conclusion: CCL1 was identified as a differentially transcribed gene in TIM-3-expressing $CD4^+$ T cells.

Gadolinium chloride ($GdCl_{3}$) was known to block Kupffer cells and generally its toxicity study based on blocking these cells. Therefore, $GdCl_{3}$ frequently used to study toxic mechanisms of hepatotoxicants inducing injury through Kupffer cells. We also tried to investigate the effect of $GdCl_{3}\;on\;CCl_{4}$ toxicity, typical hepatotoxicants. Administration of $GdCl_{3}$ to mice significantly suppressed AST (asparatate amino transferase), ALT (alanine amino transferase) levels which were increased by $CCl_{4}$ treatment. However, $GdCl_{3}$ didn't inhibit the phagocytotic activity of Kupffer cells. Malondialdehyde (MDA) is a good indicator of the degree of lipid peroxidation. In this study, MDA increased by $GdCl_{3}$ administration not by $CCl_{4}$. To understand the toxicity of $GdCl_{3}$, we analyzed global gene expression profile of mice liver after acute $GdCl_{3}$ injection. Four hundred fifty two genes were differentially expressed with more than 2-fold in at least one time point among 3 hr, 6 hr, and 24 hr. Several genes involved in fibrogenesis regulation. Several types of pro-collagens (Col1a2, Col5a2, Col6a3, and Col13a1) and tissue inhibitor of metal-loproteinase1 (TIMP1) were up regulated during all the time points. Genes related to growth factors, chemokines, and oxidative stress, which were known to control fibrogenesis, were significantly changed. In addition, $GdCl_{3}$ induced abnormal regulation between lipid synthesis and degradation related genes. These data will provide the information about influence of $GdCl_{3}$ to hepatotoxicity.

Objectives : The matrix metalloproteinases (MMPs) that participate in the extracellular matrix metabolism play a important role in the progression of pulmonary fibrosis. The effects of the MMPs are regulated by several factors including Th-1 cytokines, $interferon-{\gamma}$ ($IFN-{\gamma}$). Up to now, $IFN-{\gamma}$ is known to inhibit pulmonary fibrosis, but little is known regarding the exact effect of $IFN-{\gamma}$ on the regulation of the MMPs. This study investigated the effects of $interferon-{\gamma}$ on the pulmonary fibrosis and the expression of the lung MMP-2,-9, TIMP-1,-2, and Th-2 cytokines in aa rat model of bleomycin induced pulmonary fibrosis. Materials and methods : Male, specific pathogen-free Sprague-Dawley rats were subjected to an intratracheal bleomycin instillation. The rats were randomized to a saline control, a bleomycin treated, and a bleomycin+$IFN-{\gamma}$ treated group. The bleomycin+$IFN-{\gamma}$ treated group was subjected to an intramuscular injection of $IFN-{\gamma}$ for 14 days. At 3, 7, 14, and 28 days after the bleomycin instillation, the rats were sacrificed and the lungs were harvested. In order to evaluate the effects of the $IFN-{\gamma}$ on lung fibrosis and inflammation, the lung hydroxyproline content, inflammation and fibrosis score were measured. Western blotting, zymography and reverse zymography were performed at 3, 7, 14, 28 days after bleomycin instillation in order to evaluate the MMP-2,-9, and TIMP-1,-2 expression level. ELISA was performed to determine the IL-4 and IL-13 level in a lung homogenate. Results : 1. 7 days after bleomycin instillation, inflammatory changes were more severe in the bleomycin+$IFN-{\gamma}$ group than the bleomycin group (bleomycin group : bleomycin+$IFN-{\gamma}$ group=$2.08{\pm}0.15:2.74{\pm}0.29$, P<0.05), but 28 days after bleomycin instillation, lung fibrosis was significantly reduced as a result of the $IFN-{\gamma}$ treatment (bleomycin group : bleomycin+$IFN-{\gamma}$ group=$3.94{\pm}0.43:2.64{\pm}0.13$, P<0.05). 2. 28 days after bleomycin instillation, the lung hydroxyproline content was significantly reduced as a result of $IFN-{\gamma}$ treatment (bleomycin group : bleomycin+$IFN-{\gamma}$ group=$294.04{\pm}31.73{\mu}g/g:194.92{\pm}15.51{\mu}g/g$, P<0.05). 3. Western blotting showed that the MMP-2 level was increased as a result of the bleomycin instillation and highest in the 14 days after bleomycin instillation. 4. In zymography, the active forms of MMP-2 were significantly increased as a result of the $IFN-{\gamma}$ treatment 3 days after the bleomycin instillation, bleomycin+$IFN-{\gamma}$ group (bleomycin group : bleomycin+$IFN-{\gamma}$ group=$209.63{\pm}7.60%:407.66{\pm}85.34%$, P<0.05), but 14 days after the bleomycin instillation, the active forms of MMP-2 were significantly reduced as a result of the $IFN-{\gamma}$ treatment (bleomycin group : bleomycin+$IFN-{\gamma}$ group=$159.36{\pm}20.93%:97.23{\pm}12.50%$, P<0.05). 5. The IL-4 levels were lower in the bleomycin and bleomycin+$IFN-{\gamma}$ groups but this was not significant, and the IL-13 levels showed no difference between the experiment groups. Conclusion : The author found that lung inflammation was increased in the early period but the pulmonary fibrosis was inhibited in the late stage as a result of $IFN-{\gamma}$. The inhibition of pulmonary fibrosis by $IFN-{\gamma}$ appeared to be associated with the inhibition of MMP-2 activation by $IFN-{\gamma}$. Further studies on the mechanism of the regulation of MMP-2 activation and the effects of MMP-2 activation on pulmonary fibrosis is warranted in the future.

EP was obtained through 20% ethanol extraction of Pueraria lobata root, and the fermented form of EP, FEP, was prepared from the EP after incubating with Lactobacillus rhamnosus vitaP1. There was no significant toxicity by EP and FEP up to $1000{\mu}g/ml$ in NIH-3T3, HaCaT, and B16F10 cells. In addition to antioxidant potentials of EP and FEP determined by DPPH and ABST assays, we confirmed increase of procollagen type I and elastin synthesis by supplementation of the EP and FEP at the concentration of $50{\mu}g/ml$ using ELISA kits. The protein expression levels of matrix metalloprotease (MMP)-1, -3, and -9, those are involved in the degradation of collagen or other skin matrix proteins, were remarkably suppressed while their inhibitory protein metallopeptidase inhibitor 1 (TIMP-1) was greatly up-regulated by supplementation of the EP and FEP at a concentration of $50{\mu}g/ml$. Taken together, both EP and FEP supplementation could be involved in the suppression of the skin wrinkle formation through inhibiting degradation of collagen and stimulating the synthesis of collagen and elastin. The results showed that the anti-wrinkle potential of the EP and FEP will be a promising candidate for developing cosmeceutical compounds or products.
