Abstract
BACKGROUND Lomatogonium rotatum (LR) is traditionally used in Mongolian folk medicine as a hypoglycemic agent, but its evidence-based pharmacological effects and me-chanisms of action have not been fully elucidated.
AIM To emphasize the hypoglycemic action mechanism of LR in a type 2 diabetic rat model and examine potential biomarkers to obtain mechanistic understanding regarding serum metabolite modifications.
METHODS A high-fat, high-sugar diet and streptozotocin injection-induced type 2 diabetic rat model was established. The chemical composition of the LR was identified by high performance liquid chromatography. LR extract administrated as oral gavage at 0.5 g/kg, 2.5 g/kg, and 5 g/kg for 4 wk. Anti-diabetic effects of LR extract were evaluated based on histopathological examination as well as the measurement of blood glucose, insulin, glucagon-like peptide 1 (GLP-1), and lipid levels. Serum metabolites were analyzed using an untargeted metabolomics approach.
RESULTS According to a chemical analysis, swertiamarin, sweroside, hesperetin, coumarin, 1.7-dihydroxy-3,8-dimethoxyl xanthone, and 1-hydroxy-2,3,5 trimethoxanone are the principal active ingredients in LR. An anti-diabetic experiment revealed that the LR treatment significantly increased plasma insulin and GLP-1 levels while effectively lowering blood glucose, total cholesterol, triglycerides, low-density lipoprotein cholesterol, and oral glucose tolerance test compared to the model group. Furthermore, untargeted metabolomic analysis of serum samples detected 236 metabolites, among which 86 were differentially expressed between the model and the LR group. It was also found that LR considerably altered the levels of metabolites such as vitamin B6, mevalonate-5P, D-proline, L-lysine, and taurine, which are involved in the regulation of the vitamin B6 metabolic pathway, selenium amino acid metabolic pathway, pyrimidine metabolic pathway, and arginine and proline metabolic pathways.
CONCLUSION These findings indicated that LR may have a hypoglycemic impact and that its role may be related to changes in the serum metabolites and to facilitate the release of insulin and GLP-1, which lower blood glucose and lipid profiles.

Abstract
BACKGROUND Sulongga-4 (SL-4) is a herbal formula used in traditional Mongolian medical clinics for the treatment of peptic ulcers and gastroenteritis, even though its pharmacological mechanism has not been well characterized.
AIM To evaluate the protective effect and identify the mechanisms of action of SL-4 on gastroduodenal ulcer induced by pyloric ligation (PL) in rats.
METHODS PL was performed to induce gastric and duodenal ulcers in rats, which were then treated with oral SL-4 (1.3, 2.6, or 3.9 g/kg per day) for 15 d. PL-induced gastroduodenal ulceration. Therapeutic effects were characterized by pathological and histological evaluations and inflammatory indicators were analyzed by enzyme-linked immunosorbent assay. Microarray analyses were conducted to identify gene expression profiles of gastroduodenal tissue in PL rats with or without SL-4 treatment. The candidate target genes were selected and verified by quantitative reverse transcription polymerase chain reaction (qRT-PCR).
RESULTS SL-4 decreased histopathological features in the PL-induced ulcerated rats. SL-4 significantly (P < 0.05) decreased expression of tumor necrosis factor-α, interleukin (IL)-1β, IL-6, endotoxin, platelet-activating factor, and increased prostaglandin E2 and epidermal growth factor in ulcer tissue. Microarray analysis was used to identify a panel of candidate target genes for SL-4 acting on PL-induced ulceration. Genes included some complement and coagulation cascade and retinol metabolism pathways that are closely associated with inflammatory responses and gastric mucosal protective mechanisms. qRT-PCR showed that altered expression of the selected genes, such as CYP2b2, UGT2b1, A2m, and MASP1 was consistent with the microarray results.
CONCLUSION SL-4 exerts protective effects against PL-induced gastroduodenal ulcers via reducing inflammatory cytokines and elevating expression of gastric acid inhibitory factors. Downregulation of CYP2b2 and UGT2b1 genes in retinol metabolism and upregulation of A2m and MASP1 genes in the complement and coagulation cascades pathways are possibly involved in SL-4-mediated protection against gastroduodenal ulcer.

Abstract
OBJECTIVES Uremic pruritus is common in patients with chronic kidney disease (CKD). The retention of uremic solutes is thought to be associated with uremic pruritus. Meanwhile, activation of protease-activated receptor-2 (PAR-2) has been suggested to play an important role in pruritus. The present study was performed to investigate the effects of uremic solutes on the expression of PAR-2 in the skin. METHODS Indoxyl sulfate (IS), p-cresol (PC), and uremic sera from CKD patients were used to stimulate PAR-2 expression in normal human epidermal keratinocytes (NHEKs). Also, NHEKs were additionally pretreated with soybean trypsin inhibitor to evaluate its inhibitory effect on PAR-2 expression. Patterns of cutaneous PAR-2 expression were investigated in skin samples from five CKD patients and CKD mice. RESULTS In NHEKs, IS, PC, and sera from CKD patients significantly induced PAR-2 mRNA and protein expression. Soybean trypsin inhibitor significantly decreased PAR-2 mRNA and protein expression in NHEKs treated with IS, PC, and CKD sera. NHEKs treated with IS and PC exhibited significant increases in protease activity. Skin from both CKD patients and mice exhibited marked upregulation of PAR-2 expression compared to control skin. CONCLUSIONS Results from the present study suggest that uremic solutes either directly or indirectly affect PAR-2 expression in the skin of CKD subjects, potentially playing an important role in the pathogenesis of uremic pruritus.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Agriophyllum squarrosum (L.) Moq. is a traditional Mongol medicine generally used to treat diabetes. OBJECTIVE To investigate the protective effects and potential mechanisms of Agriophyllum oligosaccharides (AOS) on liver injury in type 2 diabetic db/db mice. MATERIALS AND METHODS The db/db mice were divided into the model group (Model), metformin group (MET), high-dose AOS group (HAOS), and low-dose AOS group (LAOS). Nondiabetic littermate control db/m mice were used as the normal control group (Control). Mice in AOS groups were treated with AOS (380 or 750 mg/kg) daily, for 8 weeks. At 8 weeks, blood samples were collected to detect lipid and enzyme parameters concerning hepatic function, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein (TP), albumin (ALB), globulin (GLB), triglyceride (TG), total cholesterol (TC), and high-density lipoprotein cholesterol (HDL-C). Random blood glucose (RBG) test, oral glucose tolerance test (OGTT), and oral maltose tolerance test (OMTT) were also conducted. Microscopy was used to observe morphological changes in the liver of AOS-treated groups. Real-time PCR was used to detect the mRNA expression, including insulin receptor substrate 2 (IRS-2), phosphatidylinositol 3 kinase (PI3K), protein kinase B (AKT), peroxisome proliferator-activated receptor (PPAR)-γ, insulin receptor (INS-R), and Glut4. Furthermore, western blotting was performed to identify proteins, including phosphorylation of IRS-2 (p-IRS-2), PI3K, p-AKT, PPAR-γ, INS-R, and Glut4. Hepatic protein expression of p-IRS-2, PI3K, p-AKT, PPAR-γ, INS-R, and Glut4 was observed using immunohistochemical staining. RESULTS AOS treatment significantly decreased RBG, OGTT, and OMTT in mice, as well as serum ALT and AST activities. AOS groups demonstrated significantly higher expressions of p-IRS-2, PI3K, PPAR-γ, p-AKT, INS-R, and Glut4 protein and IRS-2, PI3K, AKT, PPAR-γ, INS-R, and Glut4 mRNA in the liver tissue of db/db mice; the degeneration and necrosis of hepatocytes and formation of collagen fibres markedly reduced, improving the structural disorder in the liver. CONCLUSION The results suggest that AOS could protect the liver in type 2 diabetes, in part by activating insulin in the INS-R/IRS2/PI3K/AKT/Glut4/PPAR-γ signal pathway, facilitating hepatocyte proliferation, and further reducing the blood glucose levels.

Abstract
BACKGROUND AND PURPOSE Conventional MR imaging techniques cannot produce optimal images of bone structures because bone has little water and a very short T2 life span. The aim of this study was to investigate the clinical feasibility of skull MR imaging using the zero TE sequence in patients with head trauma by assessing its diagnostic image quality and quantitative measurement compared with CT images. MATERIALS AND METHODS Thirteen enrolled patients with head trauma were assessed using brain CT and skull MR imaging. Image quality was graded on a 5-point Likert scale to compare the 2 modalities. To evaluate quantitative analyses between the 2 imaging modalities, we measured skull thickness and normalized bone tissue signal. Interobserver reliability was assessed using weighted κ statistics and the intraclass correlation coefficient. RESULTS Both imaging techniques clearly depicted skull fractures in all 13 patients. The mean scores for skull MR imaging and CT were 4.65 ± 0.56 and 4.73 ± 0.45 (P = .157), respectively, with substantial interobserver agreement (P < .05). The 2 imaging modalities showed no difference in skull thickness (P = .092) and had good correlation (r 2 = 0.997). The mean value of normalized bone tissue signal among the 3 layers of the skull was relatively consistent (P = .401) with high interobserver agreement (P < .001). CONCLUSIONS Zero TE skull MR imaging has diagnostic image quality comparable with that of CT images. It also provides consistent results on the quantitative measurement of cortical bone with CT images.

Abstract
BACKGROUND Energy-delivering devices can be used to induce thermal coagulation of the eccrine sweat glands for treating primary axillary hyperhidrosis (PAH). OBJECTIVE The objective of this study was to compare the efficacy and safety of invasive, bipolar radiofrequency (RF) treatment for PAH. METHODS A split-axilla study was performed to compare the clinical outcomes of 0.5 MHz, invasive, bipolar RF treatment with treatment settings of a longer conduction time and lower power (LC/LP) vs a shorter conduction time and higher power (SC/HP) for treating PAH. RESULTS The in vivo study revealed median hyperhidrosis disease severity scale scores of 1.5 (interquartile range [IQR], 1-2) at 1 month and 1 (IQR, 1-2) at 3 months after treatment with the LC/LP setting, compared to baseline. Meanwhile, the other side of the axillae treated with the SC/HP setting showed scores of 2 (IQR, 2-2) at 1 month and 2 (IQR, 1.25-2) at 3 months. Analysis via a linear mixed model revealed a significant interaction (group, P = .011; time, P < .001; and group × time, P = .048) between treatment group and time. CONCLUSION PAH can be effectively and safely treated with invasive, multilayered, multiple-pass, 0.5-MHz, bipolar RF treatment, particularly with LC/LP.

Abstract
BACKGROUND Bipolar, alternating current radiofrequency (RF) conduction using invasive noninsulated electrodes consecutively generates independent tissue coagulation around each electrode and then, the converged coagulation columns. METHODS Two pulsed-type RF models at the on-time pulse width/pulse pack of 30 and 40 milliseconds were designed to amplify the early stage of RF-induced tissue reaction using hairless mouse skin in vivo. Then, structural and ultrastructural changes were evaluated in hairless mouse skin samples at baseline and immediately 1 day, 3 days, 7 days, and 14 days after treatment. RESULTS Immediately after pulsed-RF treatment, a few chrysanthemum-like zones of electrothermal coagulation and hypereosinophilic collagen fibers were found in the dermis and dermo-subcutaneous fat junction. Histochemical staining for periodic acid-Schiff and immunohistochemical staining for type IV collagen revealed marked thickening of basement membranes. Transmission electron microscopy demonstrated that pulsed-RF treatment resulted in higher electron-dense and remarkably thicker lamina densa, as well as increases in anchoring fibrils, compared with untreated control specimens. Furthermore, CD31-positive blood vessels were smaller in size with a slit-like luminal appearance, without excessive damage to endothelial cells. CONCLUSION Our data indicated that pulse-type, bipolar RF energy induces structural and ultrastructural changes in basement membranes and vascular components in hairless mouse skin.

Abstract
BACKGROUND Studies have shown melasma lesions to be distributed across the face in centrofacial, malar, and mandibular patterns. Meanwhile, however, melasma lesions of the periorbital area have yet to be thoroughly described. METHODS We analyzed normal and ultraviolet light-exposed photographs of patients with melasma. The periorbital melasma lesions were measured according to anatomical reference points and a hierarchical cluster analysis was performed. RESULTS The periorbital melasma lesions showed clinical features of fine and homogenous melasma pigmentation, involving both the upper and lower eyelids that extended to other anatomical sites with a darker and coarser appearance. The hierarchical cluster analysis indicated that patients with periorbital melasma can be categorized into two clusters according to the surface anatomy of the face. Significant differences between cluster 1 and cluster 2 were found in lateral distance and inferolateral distance, but not in medial distance and superior distance. Comparing the two clusters, patients in cluster 2 were found to be significantly older and more commonly accompanied by melasma lesions of the temple and medial cheek. CONCLUSION Our hierarchical cluster analysis of periorbital melasma lesions demonstrated that Asian patients with periorbital melasma can be categorized into two clusters according to the surface anatomy of the face.

Abstract
The purpose of this study was to design a repeatable universal rehabilitation program in which patients with hemiplegia can participate voluntarily, complementing physical and occupational therapies to increase voluntary exercise practice rate. Also, this study attempted to identify the relationship between psychological resilience due to the implementation of self-bedside exercise and functional recovery of activity of daily living (ADL). 12 patients with hemiplegia voluntarily participated in 8 weeks of self-bedside exercise 5 times a day and more than 5 days a week. Their program implementation, resilience, activities of daily living (MBI), upper limb motor functions (MFT), and balance ability (BBS) were analyzed and compared before and after the program. Compared to before implementing the program, significant increases were found in resilience, MBI, BBS, and MFT in the affected side after the implementation, and the resilience scores showed statistically positive correlation in MBI and MFT. Also, the change in resilience before and after the program implementation showed a statistically positive correlation. Therefore, it can be concluded that the self-bedside exercise developed in this study had a positive effect on voluntary participation in exercise as well as resilience and ADL. However, many studies which complement the psychological aspects of hemiparetic patients with stroke are still needed.

Abstract
BACKGROUND Infectious agents, especially Streptococcus sanguinis and herpes simplex virus, have long been postulated as major triggering factors for Behçet disease (BD). OBJECTIVES To identify an anti-S. sanguinis antigen reacting with serum IgA antibody in patients with BD. METHODS We detected a target protein by proteomics analysis and evaluated serum IgA reactivity of 100 patients with BD against the identified streptococcal target protein and human heterogeneous nuclear ribonucleoprotein (hnRNP) A2/B1. Homologous epitope sequences between the streptococcal target protein and human hnRNP A2/B1 were also evaluated. RESULTS Four protein bands were detected by immunoprecipitation, and chaperonin GroEL was identified by a proteomics analysis. Reactivity of serum IgA against recombinant S. sanguinis GroEL was detected in 77 of 100 patients with BD (77%) and in 21 of 70 healthy controls (30%). In addition, reactivity of serum IgA against human recombinant hnRNP A2/B1 was seen in 79 of 100 patients with BD (79%) and in eight of 70 healthy controls (11%). Among the eight distinctive epitopes with significant homology between S. sanguinis GroEL and human hnRNP A2/B1, the serum IgA reactivity of patients with BD was markedly higher with epitope 3 (hnRNP A2/B1 peptide 33-46 and GroEL peptide 57-70) and epitope 6 (hnRNP A2/B1 peptide 177-188 and GroEL peptide 347-358). CONCLUSION We identified an S. sanguinis GroEL protein as a target of serum anti-S. sanguinis IgA antibody reactivity in patients with BD. In addition, patients with BD exhibited serum IgA reactivity against homologous epitope regions between S. sanguinis GroEL and human hnRNP A2/B1.

Abstract
OBJECTIVE The purpose of our study was to assess the extrarenal length of renal arterial branches and tumour-feeding arteries on multidetector CT (MDCT) angiography, in addition to the perihilar branching patterns, with relevance to segmental artery clamping. METHODS MDCT angiograms of 64 patients with renal masses <4 cm were retrospectively reviewed by 2 radiologists. The perihilar branching patterns of the single main renal artery were assessed according to the number of pre-segmental and segmental arteries. The extrarenal lengths of segmental plus pre-segmental arteries and the tumour-feeding arteries, measured on volume-rendered images, were compared according to the vascular segmentation and the tumour location, respectively. RESULTS In the 116 kidneys, 1 pre-segmental plus 5 segmental arteries (n=48) was the most common branching pattern. The mean extrarenal length of the inferior segmental plus pre-segmental arteries (33.05 mm) and the posterior segmental plus pre-segmental arteries (32.30 mm) was longer than any of the other segmental plus pre-segmental arteries (apical, 23.87 mm; superior, 26.80 mm; middle, 29.23 mm) (p<0.05). The mean extrarenal length of the lower pole tumour-feeding arteries (35.94 mm) was longer than those of the upper and mid-pole tumour-feeding arteries (24.95 mm, 29.62 mm), with significant difference between the lower and the upper pole tumour-feeding arteries (p<0.05). CONCLUSION Tumours in the lower pole, supplied by the inferior or posterior segmental artery, may be more amenable to segmental artery clamping. ADVANCES IN KNOWLEDGE MDCT angiography with volume rendering can demonstrate the extrarenal length of tumour-feeding arteries and may help in determining the accessibility for segmental artery clamping.

Abstract
OBJECTIVES Heterogeneous nuclear ribonucleoprotein (hnRNP) A2/B1 has been identified as a target antigen of anti-endothelial cell immunglobulin (Ig)A antibodies in patients with Behçet's disease (BD). The aim was to investigate the effects of the sera from BD patients and Streptococcus sanguis on the subcellular expression of hnRNP A2/B1 in human dermal microvascular endothelial cells (HDMECs). METHOD The sera of BD patients and healthy controls (HC) as well as cultured S. sanguis were used to stimulate HDMECs. Subcellular fractions were obtained from stimulated HDMECs and were subjected to immunoblot analyses. The distribution of hnRNP A2/B1 was investigated by immunocytochemistry and direct immunofluorescence study was performed in biopsy specimens of mucosal ulcers from BD patients. RESULTS BD patients' sera increased the membrane expression of hnRNP A2/B1 in HDMECs after 12 and 24 h of incubation compared with HDMECs incubated with endothelial cell culture media and HC sera. S. sanguis also increased hnRNP A2/B1 in the cellular membrane. hnRNP A2/B1 mRNA level was also significantly upregulated in HDMECs incubated with BD patients' sera and S. sanguis. Immunocytochemistry demonstrated marked expression of hnRNP A2/B1 in the cytoplasm and cellular membrane of HDMECs incubated with BD patients' sera or S. sanguis. In addition, direct immunofluorescence experiments revealed the co-localization of serum IgA antibodies and monoclonal antibodies (mAbs) against hnRNP A2/B1 in tissue sections from ulcers of BD patients. CONCLUSIONS Our data indicate that both the sera of BD patients with active disease and S. sanguis infection are inflammatory stimuli that can induce membranous hnRNP A2/B1 expression in HDMECs.

Abstract
The effect of different phytogenic feed additives on reducing odorous compounds in swine was investigated using in vitro fermentation and analyzed their microbial communities. Soybean meal (1%) added with 0.1% different phytogenic feed additives (FA) were in vitro fermented using swine fecal slurries and anaerobically incubated for 12 and 24 h. The phytogenic FAs used were red ginseng barn powder (Panax ginseng C. A. Meyer, FA1), persimmon leaf powder (Diospyros virginiana L., FA2), ginkgo leaf powder (Ginkgo biloba L., FA3), and oregano lippia seed oil extract (Lippia graveolens Kunth, OL, FA4). Total gas production, pH, ammonia-nitrogen (NH3-N), hydrogen sulfide (H2S), nitrite-nitrogen (NO2−-N), nitrate-nitrogen (NO3−-N), sulfate (SO4−−), volatile fatty acids (VFA) and other metabolites concentration were determined. Microbial communities were also analyzed using 16S rRNA DGGE. Results showed that the pH values on all treatments increased as incubation time became longer except for FA4 where it decreased. Moreover, FA4 incubated for 12 and 24 h was not detected in NH3-N and H2S. Addition of FAs decreased (p<0.05) propionate production but increased (p<0.05) the total VFA production. Ten 16S rRNA DGGE bands were identified which ranged from 96 to 100% identity which were mostly isolated from the intestine. Similarity index showed three clearly different clusters: I (FA2 and FA3), II (Con and FA1), and III (FA4). Dominant bands which were identified closest to Eubacterium limosum (ATCC 8486T), Uncultured bacterium clone PF6641 and Streptococcus lutetiensis (CIP 106849T) were present only in the FA4 treatment group and were not found in other groups. FA4 had a different bacterial diversity compared to control and other treatments and thus explains having lowest odorous compounds. Addition of FA4 to an enriched protein feed source for growing swine may effectively reduce odorous compounds which are typically associated with swine production.

Abstract
This experiment was performed to investigate the effects of lysine (Lys) to DE ratio on growth performance, and carcass characterics in finishing barrows. Ninety six cross-bred finishing barrows ((Landrace×Yorkshire) ×Duroc, average BW 58.25±0.48 kg) were assigned as a randomized complete block design by 2 energy levels and 4 Lys:DE ratios on the basis of BW to one of 8 treatments with 3 replications with 4 animals per pen. The levels of DE and Lys:DE ratio for each treatment were i) DE 3.35 Mcal/kg, 1.5 g Lys/Mcal DE, ii) DE 3.35 Mcal/kg, 1.8 g Lys/Mcal DE, iii) DE 3.35 Mcal/kg, 2.1 g Lys/Mcal DE, iv) DE 3.35 Mcal/kg, 2.4 g Lys/Mcal DE, v) DE 3.60 Mcal/kg, 1.5 g Lys/Mcal DE, vi) DE 3.60 Mcal/kg, 1.8 g Lys/Mcal DE, vii) DE 3.60 Mcal/kg, 2.1 g Lys/Mcal DE, viii) DE 3.60 Mcal/kg, 2.4 g Lys/Mcal DE. During finishing period from 58 kg to 103 kg of BW, increased energy density in the diet increased (p<0.05) ADG and gain:feed ratio, but did not influence ADFI. As Lys:DE ratio was increased, ADG, ADFI and gain:feed ratio were improved in finishing barrows (p<0.05). There were positive interactions (p<0.05) between carcass weight, grade, and backfat thickness and energy density and Lys level (p<0.05). In conclusion, data from our current study suggest that maximum yields including ADG, gain:feed ratio, carcass weight and grade can be achieved by administrating finishing pigs with an ideal Lys:DE ratio, Lys 2.1 g/DE Mcal.

Abstract
BACKGROUND Behçet's disease (BD) and psoriasis are chronic inflammatory diseases characterized by multisystemic vasculitis and epidermal hyperplasia respectively. Although it has been found that the pathogenesis of BD and psoriasis share common perspectives, reports of patients who have both diseases in concurrence are rare. OBJECTIVES To analyse and evaluate the clinical manifestations of BD patients who have psoriasis together. METHODS Retrospective evaluation of the medical records of nine BD patients who were also diagnosed with psoriasis at the BD Specialty Clinic of Severance Hospital was carried out. We analysed the characteristics of patients and the clinical activity of both diseases, and also the effect of the treatment of one disease against the other. RESULTS Of the nine BD patients who also had psoriasis, male to female ratio was 1 : 2. Two (22.2%) patients had a complete type of BD and seven (77.8%) patients had an incomplete type of BD. For the psoriatic lesions, all nine (100%) patients were diagnosed as psoriasis vulgaris. Five (55.6%) patients had BD as the preceding disease and four (44.4%) patients had psoriasis as the preceding. All five patients who formerly developed BD followed by psoriasis had an active state of BD, but the activity of psoriasis of all nine patients was minimal to average. CONCLUSION In this study, we evaluated the clinical manifestations of nine patients who had BD and psoriasis together. Although the exact pathogenesis remains unclear, there might be some influence by each disease to the other between BD and psoriasis.

Abstract
The experiment was conducted by in vitro fermentation and bacterial community analysis to investigate the reduction of odorous compounds in response to the use of feed additives (FA) during carbohydrate overload in growing pigs. Soluble starch at 1% (control) and various FA at 0.1% Ginseng meal (FA1); Persimmon leaf (FA2); Gingko nut (FA3) and Oregano lippia (FA4) were added to fecal slurry and incubated anaerobically for 12 and 24 h. In vitro parameters and microbial diversity of the dominant bacteria following fermentation were analyzed using Denaturing Gradient Gel Electrophoresis (DGGE), band cloning and sequencing of the V3 region. Results showed that total gas production increased with the advancement of incubation (p<0.05). pH values of FAs and control groups were decreased except the FA4 group which increased somewhat from 12 to 24 h (p<0.05). Ammonia nitrogen (NH3-N) and H2S gas concentrations were comparatively lower in both stages in FA4 treatment than in the other groups (p<0.05). Hence, NH3-N concentrations in liquid phases were increased (p<0.05) from 12 to 24 h, but the trend was lowest in FA4 than in the other groups at both stages. The total VFA production was comparatively lower and butyrate levels were moderate in FA4 group than in the the other groups during both stages (p<0.05). Indirect odor-reducing compounds such as NO2, NO3 and SO4 concentrations were higher in the FA4 and FA3 than in the other groups at 24 h (p<0.05). After fermentation, ten dominant bands appeared, six of which appeared in all samples and four in only the FA4 treated group. The total number of DGGE bands and diversity was higher in the FA4-group compared to other groups. Additionally, similarity indices were lowest (71%) in the FA4, which represented a different bacterial community compared with the other groups. These findings indicate that NH3-N, H2S and VFA production was minimal, and pH was also better in the FA4 group than in the other groups. Furthermore, the conversion of odor-reducing indirect compounds or their intermediates was higher in the FA4 group in compared to the other groups. FA4 group generated less odorous products and more indirect products by in vitro fermentation at 24 h, and their microbial pattern appeared to differ from that of the other groups. These findings suggest that this particular FA could change the microbial population, which may have a beneficial effect on odor reduction. It is recommended that the oregano lippia may be supplied to growing pigs as FA along with excess carbohydrate sources to reduce the production of odorous compounds.

Abstract
BACKGROUND Flushing is defined clinically as a transient reddening of the face and other areas. Due to the transient nature of flushing, a patient may not show signs of flushing during laser treatment. OBJECTIVE The aim of this study was to evaluate the efficacy and safety of 595-nm pulsed-dye laser treatment of flushing or erythema after provocation of flushing by topical niacin cream. METHODS We retrospectively reviewed a total of 25 Korean patients with facial flushing who were treated with three sessions of 595-nm pulsed-dye laser after the application of topical niacin cream. RESULTS Follow-up results revealed that 12 of the 25 patients demonstrated marked (51-75%) clinical improvement of baseline facial erythema. Eight patients had moderate (26-50%) improvement and three demonstrated near total (≥ 75%) improvement. Two patients showed minimal to no (0-25%) improvement. We observed that the reactivity to topical niacin cream was markedly reduced in 64% of our patients after 595-nm pulsed-dye laser treatments. Minimal post-therapy facial oedema was noted in most of the patients, which usually resolved spontaneously within 2 days. Pronounced facial swelling was observed in four patients. CONCLUSION We suggest that 595-nm pulsed-dye laser treatment after provocation of flushing by topical niacin cream may provide a new treatment algorithm for facial flushing in Asians.

Abstract
BACKGROUND Rosacea is a chronic dermatosis that is usually confined to the face. A pulsed dye laser (PDL) system has been proven to be effective in treating rosacea-associated erythema and telangiectasias. Niacin is a cutaneous vasodilator that can increase the chromophore through increased blood flow. OBJECTIVES We hypothesized that increased blood flow by pretreatment with topical niacin could enhance the effect of PDL in the treatment of rosacea. METHODS Eighteen Korean patients with rosacea were recruited. Three sessions of 585-nm PDL using a subpurpuragenic dose with and without pretreatment with niacin cream were performed on randomly assigned half-faces at 3-week intervals. Erythema was assessed objectively by a polarization colour imaging system, and evaluations were also made by three blinded dermatologists. Patient satisfaction was evaluated using a 10-point visual analogue scale. RESULTS Fifteen patients completed this study. All patients showed an improvement in erythema after three sessions of PDL treatment both with and without niacin pretreatment (P = 0·023 and P = 0·009, respectively). There was no significant difference in the improvement of objective erythema between the two sides. However, based on physician assessment the overall clinical improvement on the niacin side was significantly higher (P = 0·005), and patient satisfaction was also higher on the niacin-pretreated side (P = 0·007). There were no remarkable side-effects, with the exception of transient erythema and oedema. CONCLUSIONS Pretreatment with topical niacin safely enhanced the effect of 585-nm PDL treatment of rosacea-associated erythema in Koreans. Application of niacin can be helpful in overcoming the relatively lower effect of subpurpuragenic PDL in dark-skinned Asians.

Abstract
OBJECTIVE Behçet's disease (BD) with arterial involvement is closely correlated with mortality and morbidity due to life-threatening complications such as arterial occlusion and aneurysm rupture. We aimed to determine the clinical characteristics of BD patients with aneurysms and pseudoaneurysms in the major arterial systems. METHODS Medical records of 30 BD patients diagnosed with aneurysms or pseudoaneurysms in the major arterial systems were reviewed to determine the clinical characteristics of BD, the sites and types of arterial aneurysms or pseudoaneurysms, laboratory test results, and response to treatment. RESULTS A total of 47 aneurysms and pseudoaneurysms (32 saccular aneurysms, eight fusiform aneurysms, and seven pseudoaneurysms) were detected in 30 patients. Most aneurysms and pseudoaneurysms (27 patients, 90%) had not ruptured. Symptomatic lesions presented in 21 patients (70%), and asymptomatic lesions were incidentally detected in nine (30%). Ten of the 30 patients (33.3%) presented two or more aneurysmal lesions. Recurrence was observed in five patients (16.7%) after treatment with stent graft (n = 3), graft interposition (n = 1), or graft embolization (n = 1). CONCLUSION We suggest that BD patients diagnosed with major arterial aneurysms should be further evaluated to detect possible associated venous or arterial thrombosis formations or aneurysmal lesions at other sites.

Abstract
BACKGROUND Several treatment modalities using laser devices have been used for the treatment of keloids and hypertrophic scars with various therapeutic outcomes. OBJECTIVE The purpose of this study was to describe the efficacy and safety of 1064-nm Q-switched (QS) Nd:YAG laser with low fluence on keloids and hypertrophic scars. METHODS Keloids and hypertrophic scars located at 21 anatomic sites in 12 Korean patients (10 men and 2 women; mean age 23.8 years, range 21-33) were treated using 1064-nm QS Nd:YAG laser with low fluence at 1-2 week intervals. Treatment settings were 1.8-2.2 J/cm(2), 7-mm spot size and 5-6 passes with appropriate overlapping. RESULTS Follow-up data collected 3 months after the final treatment revealed decreases in the mean score for the following lesion characteristics: pigmentation from 1.8 to 1.2; vascularity from 1.4 to 1.0; pliability from 3.0 to 2.0 and height from 2.3 to 1.8. The modified Vancouver General Hospital Burn Scar Assessment score decreased from 8.6 to 5.9 (P < 0.0001). Observed side-effects were a mild prickling sensation during treatment, and mild post-treatment erythema, both of which resolved within few hours. CONCLUSION Our results demonstrate that QS Nd:YAG laser with low fluence may be used for the treatment of keloids and hypertrophic scars.

Abstract
OBJECTIVE alpha-Enolase is a target antigen of IgM-type anti-endothelial cell antibody in patients with Behçet's disease (BD). The objective of this study was to assess the reactivity of serum anti-alpha-enolase antibodies in BD and in other rheumatologic diseases, and to evaluate the clinical significance of serum anti-alpha-enolase antibodies in BD. METHODS Enzyme-linked immunosorbent assay (ELISA) and immunoblotting were used to examine serum samples from patients with BD (n=100), systemic lupus erythematosus (SLE) (n=50), systemic sclerosis (n=21), rheumatoid arthritis (RA) (n=20), Takayasu's arteritis (n=20), dermatomyositis (n=17), mixed connective tissue disease (MCTD) (n=11), and samples from healthy volunteer donors (n=23). The medical records of patients with BD were reviewed to investigate their clinical characteristics. RESULTS Specific positive signals against recombinant human alpha-enolase were detected by IgM ELISA of serum samples from 56 of the 100 BD patients (56.0%), 24 of the 50 SLE patients (48.0%), 15 of the 21 systemic sclerosis patients (71.4%), 13 of the 20 RA patients (65.0%), 10 of the 20 Takayasu's arteritis patients (50.0%), 9 of the 17 dermatomyositis patients (52.9%), and 5 of the 11 MCTD patients (45.5%). The number of BD patients with vascular lesions was significantly higher in the anti-alpha-enolase antibody positive group than in the negative group (p=0.027). CONCLUSION We demonstrated the reactivities of serum anti-alpha-enolase antibodies in BD and other rheumatologic diseases with moderate specificity and also found that serum anti-alpha-enolase antibodies in BD can be associated with vascular system involvement.

Abstract
BACKGROUND In South Korea, military service is compulsory for all healthy young men and provides specific environmental factors, with groups working and living together in specific places for several years making varicella more transmissible to susceptible individuals. Studies of people serving in the South Korean military may provide information about the young adult male population in Korea. AIM To determine the relationship between chickenpox and atopic dermatitis (AD) in young adults over a period of 3 years. METHODS The computerized database of the Armed Forces Medical Command was examined to identify the number of reported cases of chickenpox, AD, and AD associated with chickenpox. RESULTS In total, 588 cases of chickenpox (183, 182 and 223 in the periods November 2004 to October 2005, November 2005 to October 2006, and November 2006 to October 2007, respectively) were reported. A greater number of patients were found to be infected with chickenpox in January and November, with fewer patients in August and September (P < 0.0001). Within the same periods, 1890, 2417 and 2779 patients diagnosed with AD were recorded in the Defense Medical Information System. Only 3 of 588 patients with chickenpox also had AD (0.5%). CONCLUSION In this population-based study, the epidemiological trend of chickenpox and AD over a period of 3 years within the military personnel of South Korea is shown.

Abstract
We report two cases of deep tracheal laceration in female patients after balloon dilation for benign tracheobronchial stenosis. Immediate post-procedure bronchoscopy and CT including 3D reconstructions showed deep lacerations in the posterior tracheal wall. Clinically, the patients' dyspnoea subsided and there has been no recurrence during follow-up after balloon dilation. On the follow-up 3D-reconstructed CT scans obtained 2 months and 8 months following balloon dilation, respectively, the lacerations had healed completely and there was considerable improvement in lumen size.

Abstract
The purpose of this study was to present clinical and MR imaging features of intra-articular ganglion cysts of the knee. Retrospective review of 1685 consecutive medical records and MR examinations of the knee performed at three imaging centers allowed identification of 20 patients (13 men and 7 women; mean age 35 years), in whom evidence of intra-articular ganglion cyst was seen. Of the 20 ganglion cysts, 5 were found in the infrapatellar fat pad, 10 arose from the posterior cruciate ligament, and 5 from the anterior cruciate ligament. Three of five patients with ganglion cyst in the infrapatellar fat pad had a palpable mass. In 7 of 15 patients with ganglion cyst in the intercondylar notch, exacerbation of pain occurred in a squatting position. On four MR arthrographies, ganglion cysts were an intra-articular round, lobulated, low signal intensity lesion. Five cases of fat-suppressed contrast-enhanced T1-weighted SE images demonstrated peripheral thin rim enhancement. The clinical presentation of intra-articular ganglion cyst is varied according to its intra-articular location. The MR appearance of intra-articular ganglion cyst is characteristic and usually associated with the cruciate ligament or the infrapatellar fat pad. Magnetic resonance arthrography has no definite advantage over conventional MR in the evaluation of the lesion. For intra-articular ganglion cyst in the infrapatellar fat pad, fat-suppressed contrast-enhanced MR imaging could be useful, because a thin, rim-enhancing feature of intra-articular ganglion cyst allows it to be distinguished from synovial hemangioma and synovial sarcoma.

Abstract
OBJECTIVE We describe the imaging findings of malignant mixed müllerian tumor (MMMT) of the ovary, which have not previously been reported. MATERIALS AND METHODS We experienced 13 cases of ovarian MMMT in eight patients. All patients underwent surgical resection and the MMMTs were confirmed pathologically. US (n = 8), CT (n = 8), and MRI (n = 1) examinations were performed before operation. Imaging features were analyzed retrospectively for bilaterality, tumor solidity (cystic or solid), size, and contrast enhancement of the tumor on CT and MRI. Presence of ascites and other evidence of peritoneal seeding, adjacent organ invasion, distant metastasis, and surgical staging were also evaluated. RESULTS There were bilateral ovarian MMMTs in five patients and unilateral MMMTs in three patients. Two of the MMMTs were multiseptated cystic, and 11 were mixed (solid and cystic). The diameter of the largest dimension was less than 5 cm in one case, 5-10 cm in two cases, and larger than 10 cm in 10 cases. Dense homogeneous contrast enhancement of the solid component was seen in 11 mixed masses. Ascites were found in all patients. Other evidence of peritoneal seeding and direct invasion into adjacent organ such as the uterus or sigmoid colon was seen in five patients each. Pleural metastasis was present in one patient. Surgical stages were FIGO classification IIIb and IV in one patient each, and IIIc in six patients. CONCLUSION Ovarian MMMTs usually present as aggressive, bilateral, large, solid and cystic tumors, combined with ascites, frequent peritoneal seeding, and adjacent organ invasion.

Abstract
Soft-tissue lateral neck radiography is important for diagnosing acute supraglottitis. This study aimed to determine the objective criteria for a diagnosis of acute supraglottitis from soft-tissue lateral neck radiographs in Korean adults. The parameters in 30 adult patients with acute supraglottitis were compared with those of age- and sex-matched normal 30 Korean adults. The mean of epiglottis width (EW) and aryepiglottic fold width (AEW) in the control group were 4.37 +/- 0.93 mm, 2.45 +/- 0.71 mm, respectively and in the patient group they were 15.87 +/- 3.60 mm, 6.4 +/- 2.55 mm, respectively. The sensitivity and specificity of an EW greater than 7 mm were 100%, and 100% respectively. The sensitivity and specificity of an AEW greater than 4.5 mm were 83%, and 100% respectively.

Abstract
OBJECTIVE Many investigators have studied the expression of G1 phase regulatory protein in uterine cervical cancer. However, it is unclear which step of the genetic expression participates in cyclin D1 expression and what its prognostic meaning is. The aims of this study were to evaluate the regulatory level of cyclin D1 expression and the relationship between the expression of cyclin D1 and its inhibitor, p21WAF1/CIP1, and to evaluate their impact on the prognosis of early stage cervical cancer. METHODS The presence of cyclin D1 mRNA was studied using Northern blot in 6 normal cervices and 7 invasive cervical cancer specimens. Western blot was used to detect the cyclin D1 protein in 8 normal cervices and 8 invasive cancer specimens. Thirty-two cases of FIGO stage Ib-IIa cervical cancers (28 squamous cell carcinomas, 3 adenocarcinomas, 1 adenosquamous cell carcinoma), 31 cases of cervical intraepithelial neoplasia 3 (CIN 3), and 28 normal cervices were stained for cyclin D1 and p21(WAF1/CIP1) using monoclonal antibody. Statistical analysis was performed to assess the differences in expression and their prognostic significance. RESULTS. Cyclin D1 mRNA was found to be underexpressed in cervical cancer. Western blot also revealed underexpression of cyclin D1 protein in cervical cancer compared to normal controls. Positive immunohistochemical staining of cyclin D1 was noted in 28/28 (100%) of the normal controls, 1/31 (3%) cases of CIN 3, and 9/32 (28%) cases of invasive cancer. The number of positively stained specimens was lower than that of normal controls in CIN 3 and cervical cancer specimens (P = 0.005). Fifteen of 28 (54%) normal controls, 15/31 cases (48%) of CIN 3, and 27/32 cases (84%) of invasive cancer were proved positive for p21WAF1/CIP1 immunohistochemistry. p21WAF1/CIP1 was more highly expressed in cervical cancer than in that of either normal controls or CIN specimens (P = 0.001). Positive immunostaining of cyclin D1 and p21WAF1/CIP1 was not related to high-risk factors (pelvic lymph node metastasis, deep cervical stromal invasion, parametrial invasion, large tumor size, and unusual histologic type) and human papilloma virus infection. Positive cyclin D1 immunostaining was associated with decreased disease-free survival and a lower overall survival (P = 0.0175 and 0.0189, respectively). On multivariate analysis, positive cyclin D1 expression was a significant prognostic variable for recurrence (P = 0.0004). CONCLUSION Underexpression of cyclin D1 was regulated at the level of transcription in cervical cancer. Although cyclin D1 was underexpressed in cervical neoplasias, it was more frequently expressed in malignant lesions. p21WAF1/CIP1 was more highly expressed in cervical cancers than in either normal cervices or CIN 3 specimens. Unfavorable prognoses were associated with cyclin D1 expression, and not with the expression of its inhibitor, p21WAF1/CIP1.We conclude that immunohistochemical assessment of cyclin D1 can be a useful molecular marker for predicting prognosis in early stage cervical cancer of the uterus.

Abstract
The induction of interleukin-6 (IL-6), using a proinflammatory cytokine (tumor necrosis factor-alpha), was studied in a human osteoblast cell line (MG-63) in relation to p38 mitogen-activated protein kinase (MAPK) and nuclear factor (NF)-kappaB transcription factor. When added to MG-63 cells, tumor necrosis factor-alpha (TNF-alpha) had a stimulatory effect on the production of IL-6, and this elevation was significantly reduced by SB203580, a specific p38 MAPK inhibitor. In addition, the stimulation of IL-6 release was also reduced by pyrrolidine dithiocarbamate (PDTC) or NF-kappaB SN50, which has been reported to be a potent NF-kappaB inhibitor. Both the NF-kappaB inhibitors in the presence of SB203580 had a more inhibitory effect on IL-6 release. In this study, TNF-alpha stimulated NF-kappaB binding affinity as well as p38 MAP kinase activation, leading to the release of IL-6. However, the specific inhibitor of p38 MAPK, SB203580, had no effect on TNF-alpha-induced NF-kappaB activation and both NF-kappaB inhibitors failed to reduce the p38 MAPK activation in the TNF-alpha-stimulated osteoblasts. In addition, inhibition of p38 MAPK partially, but significantly, impaired TNF-alpha-regulated release of osteocalcin, an important differentiation marker in osteoblasts. These results strongly suggest that both p38 MAPK and NF-kappaB are required in TNF-alpha-induced IL-6 synthesis and that these two TNF-alpha-activated pathways can be primarily dissociated. Furthermore, p38 MAPK may play a significant role in differentiation in MG-63 cells.

Abstract
Ceramide has been proposed as a second messenger molecule implicated in a variety of biological processes, including apoptosis. Recently, it has been reported that tumor necrosis factor-alpha (TNF-alpha) activates the release of ceramide and that ceramide acts as a mediator for the TNF-alpha-induced stimulation of the binding affinity of nuclear factor-KB (NF-KB), a ubiquitous transcription factor of particular importance in immune and inflammatory responses. In this study we demonstrate that dexamethasone, which reduces the production of ceramide, significantly inhibits TNF-alpha-induced activation of NF-KB, c-Jun N-terminal kinase, also known as stress-activating protein kinase, caspase-3-like cysteine protease, redistribution of cytochrome c, and apoptosis in MC3T3E1 osteoblasts. Compared with TNF-alpha-induced JNK activation, ceramide elicits a more rapid activation of JNK within 30 min. C2-ceramide activates NF-KB and caspase-3 like protease to the same degree and with kinetics similar to those of TNF-alpha. This study provides evidence that the release of ceramide may be required as a second messenger in TNF-alpha-induced apoptosis. These results also suggest a regulatory role for dexamethasone in TNF-alpha-induced apoptosis via inhibition of ceramide release. Therefore, our in vitro results suggest that therapies targeted at the inhibition of ceramide release may abrogate inflammatory processes in TNF-alpha-related diseases, including rheumatoid arthritis and periodontitis.

Abstract
Glomus tumor occurs only rarely in the stomach. This benign intramural mass is located most frequently in the distal half of the stomach. We experienced two cases of glomus tumor of the stomach which were examined with helical CT and were confirmed pathologically. Both tumors were well-marginated solitary lesions, located in the gastric antrum. On the early-phase helical CT, an intact overlying mucosa was demonstrated in both cases, and both tumors showed a dense homogeneous contrast enhancement, which persisted to the delayed phase.
