Abstract
PURPOSE The purpose of this study was to evaluate the efficacy and safety of red ginseng oil (RXGIN) in men with lower urinary tract symptoms. MATERIALS AND METHODS Men aged between 40 and 75 years with a total International Prostate Symptom Score (IPSS) of 8 to 19 points were recruited from April 2020 to December 2020. Subjects were randomly assigned to either the RXGIN group or the control group in a 1:1 ratio and received either RXGIN or placebo daily for 12 weeks. For the primary outcome, changes in IPSS scores at 6 and 12 weeks from baseline were analyzed. The secondary outcomes were changes in International Index of Erectile Function (IIEF), maximum urinary flow rate, and post-void residual volume at weeks 6 and 12 compared to baseline. Urine analysis and blood tests were additionally performed for safety assessment. RESULTS A total of 88 subjects (RXGIN group, 46; control group, 42) completed the study. The total IPSS and IPSS subscores (residual urine sensation, frequency, intermittency, urgency, weak stream, straining, nocturia, and quality of life) were significantly improved in the RXGIN group compared to the control group at weeks 6 and 12. Total IIEF and sexual desire were significantly improved in the RXGIN group at week 6 and week 12, respectively, but there were no significant changes in the level of serum testosterone or dihydrotestosterone. The serum prostate-specific antigen showed significant decrease at weeks 12. No serious adverse events leading to discontinuation of the study drug were observed in the RXGIN group. CONCLUSIONS Red ginseng oil (RXGIN) appears to be safe and effective in improving lower urinary tract symptoms in men and may also improve some aspects of sexual function.

Abstract
Background To evaluate the efficacy and safety of Cervi Parvum Cornu, Angelicae Gigantis Radix and Glycyrrhizae Radix complex (CAG) in men with moderate lower urinary tract symptoms (LUTS). Materials and methods From November 2020 to January 2022, participants with International Prostate Symptom Score (IPSS) of 12-19 in two centers were recruited and randomize into three groups: a CAG 500 mg/day group (CAG 500), a CAG 1000 mg/day group (CAG 1000), and a placebo group (PG). They were treated for 12 weeks. The primary endpoint was change of IPSS at the end of study from baseline. Secondary end points included change of prostate specific antigen (PSA), testosterone, dihydrotestosterone (DHT), maximum urinary flow rate (Q max), post-void residual volume (PVR), International Index of Erectile Function (IIEF), and drug safety. Results A total of 103 patients were able to finish the study according to the study protocol. Total IPSS and sub-scores (residual urine sensation, frequency, weak stream, hesistancy, nocturia, and quality of life) in CAG 500 and CAG 1000 were significantly improved at the 12th week compared to those of the PG. Changes of serum PSA, DHT, and testosterone levels at the 12th week from baseline did not show significant differences among the three groups. Q max and PVR changes did not show significant differences among the three groups either. Total IIEF and sub-scores (erectile function, orgasmic function, sexual desire, intercourse satisfaction) in CAG 1000 were significantly improved at 12th week compared to those in PG. No significant adverse events were found. Conclusions CAG is well tolerated in patients with moderate LUTS. Treatment with CAG for 12 weeks has a therapeutic effect on moderate LUTS.

Abstract
To investigate the optimal scanning parameters of dual-energy computed tomography (DECT), which can accurately determine sensitivity (the detectability of urinary stones) and accuracy (the composition matching of urinary stones), and to apply them to clinical trials. Fifteen urinary stones were chemically analyzed, and their chemical compositions were considered a reference standard with which we compared the uric acid (UA) and non-UA compositions determined using DECT. The urinary stones were placed inside a bolus and scanned with a dual-source CT scanner under various selected dual-energy conditions (A to X) using various solid water phantom thicknesses. These datasets were analyzed using the Siemens syngo.via software tool (integrated into the CT system) for matching the sensitivity and accuracy assessments. This study showed that 80% of the highest sensitivity (detection of urinary stones) and 92% of the highest accuracy (composition matching of urinary stones) were achieved under condition A (a collimation beam width setting of 2 × 32 × 0.6 mm, an automatic exposure control setting of 80/sn140 peak kilovoltage, and a slice thickness of 0.5/0.5 mm) (P < 0.05). Application of the DECT energy parameters presented in the study will help identify the sensitivity and accuracy of UA and non-UA stone analysis, even in patients with small-sized urinary stones and in conditions difficult for analysis.

Abstract
535 Background: Although immune checkpoint inhibitor (ICI) is regarded as a breakthrough in bladder cancer (BC) therapy, only a limited fraction of patients benefit from it. Thus, we aim to establish gene signature (iGS) and develop a model that predicts the response of ICI for the patients with BC. Methods: We collected bulk RNA expression data from BC cohort (GSE176307) receiving ICI and single-cell sequencing data from patients with BC (GSE135337). Single-sample gene set enrichment (ssGSEA) analysis was used to develop predictive iGS. Clinical benefit of ICI was defined as a complete or partial response or stable disease at week 24. The gene ontology (GO) and pathway enrichment analysis were established through DAVID database. Logistic regression model was constructed with iGS and clinical factors. The final model was validated by the K-fold cross validation technique. Results: We integrated bulk RNA expression data and single-cell sequencing data, and identified subset of cells (N= 157) that were associated with the overall survival (OS) of patients receiving ICI. These cells were compared with all other cells, and 85 up-regulated differentially expressed genes (DEGs) were identified. DEGs were mainly enriched in 'antigen processing and presentation of exogenous peptide antigen via MHC class II', 'peptide antigen assembly with MHC class II protein complex' and 'immune response' in the biological process enrichment analysis. High iGS score, that was derived from ssGSEA, was significantly associated with longer OS in multivariate Cox regression analysis (Hazard ratio: 0.40, P = 0.02) Final prediction model for clinical benefit included iGS score [odds ratio (OR) = 3.89], tumor mutation burden (OR = 9.8) and age (OR = 0.93) with accuracy of 0.80 and an area under the receiver operator characteristic curve (AUROC) of 0.77. Conclusions: We showed the potential of iGS from bulk and single cell RNA sequencing for predicting clinical benefit of ICI in BC.

Abstract
Background Because of the contradictory results, more epidemiologic data is needed to determine if metabolic syndrome is a risk factor for developing prostate cancer. This study investigated whether metabolic syndrome-like components affect the incidence of prostate cancer in a Korean population. Methods Men over 50 years of age who underwent health examinations in 2009 were followed until December 2015 (n=1,917,430) using National Health Insurance System data. Subjects were divided into three groups according to the number of metabolic syndrome-like components. The predictive accuracy of age for prostate cancer was assessed by the Youden index and multivariate adjusted Cox regression analysis was used to analyze the effect of metabolic syndrome-like components on prostate cancer development. Results The risk of prostate cancer increases with age, and the best cutoff age for prostate cancer detection was 62 years (the maximum value of the Youden index). When stratified by the number of metabolic syndrome-like components, the age with the highest Youden index of each group is still 61 or 62 years. In multivariate adjusted Cox regression analysis, there was no statistically significant difference in the incidence rate among the non-component group, the group with 1 or 2 components, and the group with ≥3 components. Conclusions The current study found that there was no statistically significant association between metabolic syndrome and prostate cancer development in a Korean population. However, results of this study should be interpreted with consideration due to several limitations including the diversity of definitions of metabolic syndrome components.

Abstract
Objective: To evaluate the clinicopathological characteristics of grade group 1 (GG1) prostate cancer in Korean populations. Methods: We retrospectively analyzed 492 consecutive radical prostatectomy specimens from our institution, which included those from 322 men with clinical GG1 and 170 with clinical GG2 tumors between years 2009 and 2018. The incidence of Gleason score (GS) upgrading, extraprostatic extension (EPE), and seminal vesicle invasion (SVI) were evaluated in patients with clinical GG1. In pathological GG1 cases, the distribution of adverse pathological features including EPE, lymphovascular invasion (LVI), perineural invasion (PNI), and biochemical recurrence (BCR) was analyzed. Results: Altogether, 78 (24.2%) out of 322 men in the clinical GG1 group demonstrated upgrading of GS, including 19 men with pathological Gleason score 4 + 3 = 7 and 6 with ≥ pathological Gleason score 4 + 4 = 8 cases. EPE was found in 37 (11.5%) and 22 (8.9%) men in clinical GG1 and pathological GG1 group, respectively. The incidence of LVI and PNI in the pathological GG1 cases was 2.8% (n = 7) and 28.6% (n = 71), respectively. BCR was observed in 4 men in pathological GG1 T2 (n = 226) and 2 men in GG1 T3 (n = 22) group. When we compared the pathological features between pathological GG1 T3 vs. GG2 T2, there was no statistical differences in the incidence of LVI and PNI between the two groups. Conclusions: Contrary to the current concept that GG1 is almost always clinically insignificant, it seems that GG1 still possess its respectable position as a group of cancer with aggressiveness. These findings should be kept in mind when deciding on treatment options for prostate cancer patients in the Asian populations.

Abstract
Purpose To analyze the difference in the prediction accuracy with an active surveillance (AS) protocol between two eras (pre-International Society of Urological Pathology [pre-ISUP]-2014 vs. post-ISUP2014). Materials and Methods We retrospectively analyzed 118 candidates for AS who underwent radical prostatectomy between 2009 and 2017. We divided our patients into two groups (group 1 [n=57], operation date 2009–2015; group 2 [n=61], operation
date 2016–2017). Pathologic slides in group 1 were reviewed to distinguish men with cribriform pattern (CP) because the determination of Gleason scores in old era had been based on pre-ISUP2014 classification. Postoperative outcomes in the two eras were analyzed twice: first, all men in group 1 vs. group 2; second, the remaining men after excluding those with CPs in group 1 vs. group 2. Results The proportion of men with insignificant prostate cancer (iPCa) was significantly lower in group 1 than in group 2 (36.8% vs. 57.4%, p=0.040). After excluding 11 men with CPs from group 1, those remaining (46 men) were compared again with group 2. In this analysis, the proportion of men with iPCa was similar between the two groups (old vs. contemporary
era: 41.3% vs. 57.4%, p=0.146). Nine of 11 men with CP had violated the criteria for iPCa in the earlier comparison. Conclusions The accuracy of the AS protocol has been affected by the coexistence of CPs and pure Gleason 6 tumors in the pre-ISUP2014 era. We suggest to use only contemporary (post-ISUP2014) data to analyze the accuracy with AS protocols in future studies.

Abstract
Objective To analyze the association between neutrophil‐to‐lymphocyte ratio (NLR) and intravesical prostatic protrusion (IPP) in men with benign prostatic hyperplasia. Methods Two hundred and fifty men aged >50 years who presented with lower urinary tract symptoms at our institution between 2014 and 2018 were analyzed. Pearson's method was used for analysis of the correlation between NLR and IPP. Multivariate logistic regression analysis was used to identify predictors of IPP. Further analysis according to total prostate volume (TPV) was performed. Results The NLR correlated positively with IPP (Pearson's r = 0.459, P < 0.001) and was an independent predictor of IPP ≥10 mm (odds ratio, 2.95; 95% confidence interval, 1.59–5.47; P = 0.0006). Among the 142 men with prostates <40 cm3, mean NLR was 2.50 ± 0.71 in those with IPP ≥10 mm and 1.71 ± 0.57 in those with IPP < 10 mm (P < 0.001). The NLR differed significantly between those with a prostate <40 cm3 and IPP ≥10 mm and those with a larger prostate and IPP < 10 mm (2.50 ± 0.71 vs 2.07 ± 0.77, respectively; P = 0.020). Conclusions NLR can be used as a surrogate marker for presence of IPP. Its clinical value would be especially important in men with a small prostate gland but high IPP. The NLR seemed to be more strongly correlated with IPP than with TPV.

Abstract
PURPOSE To analyze postoperative outcomes after arthroscopic transosseous triangular fibrocartilage complex (TFCC) foveal repair and identify factors affecting the clinical outcomes. METHODS This study retrospectively enrolled patients who were treated for TFCC foveal tears by arthroscopic transosseous TFCC foveal repair. The diagnosis of TFCC foveal tear was made based on medical history, physical examination, and magnetic resonance imaging, with confirmation via arthroscopic examination. Outcome evaluation was completed at a minimum of 2 years postoperatively, and patients were classified into 2 groups according to the minimal clinically important difference of the Patient-Rated Wrist Evaluation. Various factors including age, sex, trauma history, body mass index, symptom duration, hand dominance, ulnar variance, subluxation of the distal radioulnar joint, preoperative pain score, and functional status, as well as the cross-sectional area (CSA) of the pronator quadratus (PQ) muscle, were retrospectively analyzed using both univariate and multivariate analyses. RESULTS During the study period, 42 patients were treated for TFCC foveal tears. The functional status significantly improved after surgery. Overall, 27 and 15 patients showed good and poor functional outcomes, respectively, which were assessed according to the minimal clinically important difference of the Patient-Rated Wrist Evaluation. On univariate analysis, clinical outcomes were better in male patients (P = .035), younger patients (P = .022), and those with higher CSAs of the PQ muscles (P < .001). However, on multivariable logistic regression analysis, only a higher CSA of the PQ muscle was identified as an independent prognostic factor affecting clinical outcome after TFCC foveal repair (P = .004). CONCLUSION Arthroscopic transosseous TFCC complex foveal repair led to satisfactory results. However, lower PQ muscle CSA on magnetic resonance imaging was the most independent prognostic factor negatively affecting clinical outcomes. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
OBJECTIVE To investigated the anti-inflammatory and antimicrobial effects of anthocyanins extracted from black soybean on the chronic bacterial prostatitis (CBP) rat model. METHODS The Sprague-Dawley rats were divided into 4 groups, including control, ciprofloxacin, anthocyanins and anthocyanins with ciprofloxacin groups (n=8 in each group). Then, drip infusion of bacterial suspension (Escherichia coli Z17 O2:K1:H-) into Sprague-Dawley rats was conducted to induce CBP. In 4 weeks, results of prostate tissue, urine culture, and histological analysis on the prostate were analyzed for each group. RESULTS The use of ciprofloxacin, anthocyanins, and anthocyanins with ciprofloxacin showed statistically significant decreases in bacterial growth and improvements in the reduction of prostatic inflammation compared with the control group (P<0.05). The anthocyanins with ciprofloxacin group showed a statistically significant decrease in bacterial growth and improvement in prostatic inflammation compared with the ciprofloxacin group (P<0.05). CONCLUSIONS These results suggest that anthocyanins may have anti-inflammatory and antimicrobial effects, as well as a synergistic effect with ciprofloxacin. Therefore, we suggest that the combination of anthocyanins and ciprofloxacin may be effective in treating CBP to obtain a higher rate of treatment success.

Abstract
Herein, we describe a case of uterine calcification in the uterus of a pig without pregnancy loss. The recipient underwent cloned embryo transfer and Cesarean section for safe delivery of cloned piglets. During the Cesarean section, 4 white, star-like, (2 × 2 × 2) cm, calcified structures were found within the endometrial cavity. Despite dystrophic calcification around the placenta, healthy cloned piglets were produced successfully. To our knowledge, this is the first reported case of dystrophic calcification occurring within the uterus in a pregnant pig.

Abstract
OBJECTIVE To investigate the anti-oxidative stress and preventive effect of modified Gongjin-dan (WSY-1075) in a detrusor underactivity rat model. METHODS Rats were randomly allocated to three groups: shamoperated (control), bladder outlet obstruction-induced detrusor underactivity (BOO-DU), and BOO-DU with WSY-1075 (WSY) groups. WSY-1075 was orally administrated to rats 200 mg daily for 2 weeks prior to the operation and 4 weeks after the operation. Bladder outlet obstruction was surgically induced in rats by ligation around the urethra avoiding total obstruction. Cystometrography was conducted on rats in each group for examination of bladders. RESULTS Compared with the control group, bladder outlet obstruction led to a significant increase in oxidative stress with consequent changes to molecular composition, and decrease in maximal detrusor pressure (P<0.05). WSY-1075 treatment significantly suppressed oxidative stress and prevented degenerative and dysfunctional changes in bladder, as compared with BOO-DU group (P<0.05). CONCLUSION WSY-1075 had beneficial effect on prevention of BOO-DU.

Abstract
BACKGROUND Houttuynia cordata Thunb (HC) is a traditional herbal medicine widely used in Asia for the treatment of patients with alopecia, usually in combination with other two herbal medicines (Perilla frutescens var. acuta (PFVA) and green tea (GT)). However, the effect of this herbal complex has not been clearly demonstrated. We sought to determine the hair growth-promoting effect of this herbal complex (HC, PFVA, and GT) in the animal model. METHODS Six-week-old male C57BL/6 mice were randomly divided into four groups (negative control, finasteride (1 mg/kg) as a positive control, and two (200 and 400 mg/kg) concentrations of the herbal complex as experimental groups) and were fed its corresponding medications orally for 25 days. Hair growth was evaluated visually and microscopically. Western blot analysis for insulin-like growth factor (IGF)-1 and transforming growth factor (TGF)-β1 was performed. RESULTS The herbal complex exhibited hair growth-promoting activity in C57BL/6 mice. Grossly, the area of hair regrowth was 55.1 (±3.8) %, 70.2 (±6.3) % and 83.5 (±5.7) % in negative control, herbal complex 200 mg/kg and 400 mg/kg group, respectively. In histologic examination, the hair follicle count in deep subcutis was 2.6 (±0.7), 5.8 (±0.7) and 8.6 (±1.2) and the diameter of hair follicles was 11.9 (±5.0) μm, 17.4 (±3.9) μm and 22.8 (±5.2) μm in negative control, herbal complex 200 and 400 mg/kg group, respectively. The expression of IGF-1 was 0.14 (±0.01), 0.23 (±0.02) and 0.24 (±0.01) and the expression of TGF-β1 was 0.26 (±0.01), 0.19 (±0.02) and 0.15 (±0.01) in negative control, the 200 and 400 mg/kg group, respectively. CONCLUSIONS This data provides adequate preliminary experimental evidence to support the hair regeneration effect of this herbal complex.

Abstract
The aim of this study was to investigate the association between urinary incontinence (UI) and peptic ulcer (PU) and how this is related to psychological stress in Korean women by analyzing the data from the Korea National Health and Nutrition Examination Survey IV (KNHANES).A nationally representative sample of data on 7475 Korean women ≥19 years of age from the KNHANES 2008 to 2010 was included. Physician-diagnosed UI and PU were assessed using questionnaires and surveys. Psychological stress was assessed through a questionnaire using a 4-point Likert scale. Data were analyzed using logistic regression to determine the association between UI and PU according to the level of psychological stress perception.PU was found in 1.41% of the total population. Breaking this down by the existence of UI, PU was found in 3.5% of the population with UI, and 1.4% of the population without UI, which showed a significant difference. A statistically significant trend for increasing prevalence of UI and PU with increasing psychological stress perception levels was found among the study population. Multivariable logistic regression analyses for PU showed that UI was significantly associated with a higher probability of PU in an adjusted model, which means that members of the population with UI were more likely to have PU than those without UI. A higher level of psychological stress perception was also significantly associated with increased odds of PU in the adjusted model.UI could potentiate the development of PU through increasing levels of psychological stress perception.

Abstract
PURPOSE To investigate the efficacy and safety of naftopidil for benign prostatic hyperplasia (BPH) patients, mainly focusing on changes in blood pressure (BP). MATERIALS AND METHODS Of a total of 118 patients, 90 normotensive (NT) and 28 hypertensive (HT) patients were randomly assigned to be treated with naftopidil 50 mg or 75 mg for 12 weeks, once-daily. Safety and efficacy were assessed by analyzing changes from baseline in systolic/diastolic BP and total International Prostate Symptom Score (IPSS) at 4 and 12 weeks. Adverse events (AEs), obstructive/irritative subscores, quality of life (QoL) score, maximum urinary flow rate (Qmax), and benefit, satisfaction with treatment, and willingness to continue treatment (BSW) questionnaire were also analyzed. RESULTS Naftopidil treatment decreased mean systolic BP by 18.7 mm Hg for the HT 50 mg group (p<0.001) and by 18.3 mm Hg for the HT 75 mg group (p<0.001) and mean diastolic BP by 17.5 mm Hg for the HT 50 mg group (p<0.001) and by 14.7 mm Hg for the HT 75 mg group (p=0.022). In the NT groups (both naftopidil 50 mg and 75 mg), naftopidil elicited no significant changes in BP from baseline values. After 12 weeks, naftopidil 50 and 75 mg groups showed significant improvements in IPSS scores (total, obstructive/irritative subscores, QoL score) and Qmax from baseline. AEs were reported in 7.8% (50 mg group) and 2.9% (75 mg group) of patients. In both the 50 mg and 75 mg groups, >86% of all patients agreed to continue their current medications. CONCLUSION Our results suggest that naftopidil treatment in BPH patients with hypertension allows for optimal management of BP within the normal range.

Abstract
OBJECTIVES To identify the age- and sex-specific antimicrobial susceptibility patterns of Gram-negative bacteria (GNB) in outpatient febrile urinary tract infections (UTIs) in Korea. METHODS A total 2262 consecutive samples collected from patients aged 1-101 years with febrile UTIs, during the period January 2012 to December 2014, were analyzed in this multicentre, retrospective cohort study. RESULTS The sensitivities to cefotaxime and cefoxitin were over 85% for females but under 75% for males. Sex played an important role in the susceptibility of GNB to cefotaxime (p<0.001) and cefoxitin (p<0.001). The sensitivity to ciprofloxacin (age >20 years) was under 75% in both sexes, and was not influenced by sex (p=0.204). Age distributions of the incidences of resistance to cefotaxime, cefoxitin, and ciprofloxacin (age >20 years) were similar to the age distribution of the incidence of GNB, which indicates that the resistance patterns to these drugs were not affected by age (Kolmogorov-Smirnov test, female/male: p=0.927/p=0.509, p=0.193/p=0.911, and p=0.077/p=0.999, respectively). CONCLUSIONS Age is not a considerable factor in determining the antibiotic resistance in febrile UTIs. Ciprofloxacin should be withheld from both sexes until culture results indicate its use. Second- or third-generation cephalosporins such as cefoxitin and cefotaxime can be used empirically only in females.

Abstract
BACKGROUND To assess the anti-adhesive effect of treatment with hyaluronic acid-carboxymethylcellulose following laparoscopic radical prostatectomy. METHODS This was a randomized, controlled, single-blind, parallel-group study using hyaluronic acid-carboxymethylcellulose in patients who underwent laparoscopic radical prostatectomy. Sixty patients were enrolled in the study. All patients were randomly assigned to either the hyaluronic acid-carboxymethylcellulose treatment group (n = 30) or the control group (n = 30). Viscera slide ultrasounds and plain X-rays were obtained at enrollment (V0), postoperative week 12 (V1), and 24 (V2). The primary end point was the difference in the excursion distance in the viscera slide ultrasound between V0 and V2. RESULTS A total of 50 patients completed this study. The average excursion distance at V2 in the experimental group (n = 25) was significantly longer than in the control group (n = 25, 2.7 ± 1.2 vs. 1.3 ± 1.0 cm, respectively; p < 0.001). The differences in the V0 and V2 excursion distances were significantly higher in the control group than in the experimental group (1.48 ± 1.5 vs. 2.9 ± 1.2 cm, respectively; p < 0.001). None of patients showed adverse events associated with the use of hyaluronic acid-carboxymethylcellulose. CONCLUSION This randomized study demonstrated that hyaluronic acid-carboxymethylcellulose treatment resulted in a reduction in bowel adhesion to the abdominal wall after laparoscopic pelvic surgery and had good clinical safety.

Abstract
Objective To investigate the association between insulin resistance (IR) and urinary incontinence in Korean adult women by analyzing the data from the Korea National Health and Nutrition Examination Survey IV (KNHANES) 2007–2009 Methods A nationally representative sample of 5318 non-diabetic Korean women ≥19-years-of-age (3043 premenopausal and 2275 postmenopausal women) was included from KNHANES 2008–2010. IR was measured using the homeostasis model assessment of IR (HOMA-IR). Participants in the highest and lowest quartile of HOMA-IR were defined as insulin-resistant and insulin-sensitive respectively. Women who have current physician-diagnosed urinary incontinence were classified as having urinary incontinence. Results Incontinence was found in 9.18% of the total population, 8.51% of the premenopausal population, and 10.86% of the postmenopausal population. The prevalence of incontinence increased with age, reaching a peak at 60-69-years-of-age. The prevalence of urinary incontinence increased significantly with higher HOMA-IR quartiles in pre- and post-menopausal women (p for linear association = 0.0458 and 0.0009 respectively). Among post-menopausal women, those in the highest quartile of HOMA-IR were significantly more likely to have urinary incontinence compared to those in the lowest quartile [adjusted odds ratio, 1.72; 95% confidence interval, 1.07–2.77]. However premenopausal population exhibited no association between incontinence and HOMA-IR quartiles Conclusion Our results suggest that the prevalence of incontinence increased across HOMA-IR in non-diabetic adult women, and especially, IR might be a risk factor for incontinence in postmenopausal non-diabetic women.

Abstract
PURPOSE To investigate the effects of anthocyanins extracted from black soybean, which have antioxidant activity, on apoptosis in vitro (in hormone refractory prostate cancer cells) and on tumor growth in vivo (in athymic nude mouse xenograft model). MATERIALS AND METHODS The growth and viability of DU-145 cells treated with anthocyanins were assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and apoptosis was assessed by DNA laddering. Immunoblotting was conducted to evaluate differences in the expressions of p53, Bax, Bcl, androgen receptor (AR), and prostate specific antigen (PSA). To study the inhibitory effects of anthocyanins on tumor growth in vivo, DU-145 tumor xenografts were established in athymic nude mice. The anthocyanin group was treated with daily oral anthocyanin (8 mg/kg) for 14 weeks. After 2 weeks of treatment, DU-145 cells (2×10⁶) were inoculated subcutaneously into the right flank to establish tumor xenografts. Tumor dimensions were measured twice a week using calipers and volumes were calculated. RESULTS Anthocyanin treatment of DU-145 cells resulted in 1) significant increase in apoptosis in a dose-dependent manner, 2) significant decrease in p53 and Bcl-2 expressions (with increased Bax expression), and 3) significant decrease in PSA and AR expressions. In the xenograft model, anthocyanin treatment significantly inhibit tumor growth. CONCLUSION This study suggests that anthocyanins from black soybean inhibit the progression of prostate cancer in vitro and in a xenograft model.

Abstract
Whereas it has been assumed that genetically modified tissues or cells derived from somatic cell nuclear transfer (SCNT) should be accepted by a host of the same species, their immune compatibility has not been extensively explored. To identify acceptance of SCNT-derived cells or tissues, skin grafts were performed between cloned dogs that were identical except for their mitochondrial DNA (mtDNA) haplotypes and foreign gene. We showed here that differences in mtDNA haplotypes and genetic modification did not elicit immune responses in these dogs: 1) skin tissues from genetically-modified cloned dogs were successfully transplanted into genetically-modified cloned dogs with different mtDNA haplotype under three successive grafts over 63 days; and 2) non-transgenic cloned tissues were accepted into transgenic cloned syngeneic recipients with different mtDNA haplotypes and vice versa under two successive grafts over 63 days. In addition, expression of the inserted gene was maintained, being functional without eliciting graft rejection. In conclusion, these results show that transplanting genetically-modified tissues into normal, syngeneic or genetically-modified recipient dogs with different mtDNA haplotypes do not elicit skin graft rejection or affect expression of the inserted gene. Therefore, therapeutically valuable tissue derived from SCNT with genetic modification might be used safely in clinical applications for patients with diseased tissues.

Abstract
Purpose The purpose of this study is to compare changes in voiding pattern after midurethral sling surgery (MUS) between the stress urinary incontinence (SUI) group and the overactive bladder (OAB)+SUI group. Materials and Methods From January 2008 to February 2011, a retrospective survey was conducted of 225 female patients who had been diagnosed with SUI and undergone MUS. The subjects were divided into the SUI group and the OAB+SUI group. Changes in the overactive bladder symptom score (OABSS) and American Urological Association-Symptom Index (AUA-SI) before and three months after the MUS were compared. Results Of the 225 patients, 165 patients (73.3%) were classified as SUI group, and 60 patients (26.7%) were classified as OAB+SUI group. The mean age of the subjects was 54.7 years (range, 31-80 years), and the mean age of patients was 53.9 years (range, 34-80 years), and 56.8 years (range, 31-78 years) in the SUI group and OAB+SUI group. In SUI group, voiding symptom and storage symptom among the AUA-SI were significantly increased (p<0.05). OABSS were slight increased, but was statistically insignificant (p=0.847). In OAB+SUI group, voiding symptom score and OABSS showed a significant increase (p<0.05), but storage symptom score showed an insignificant increase (p=0.790). Conclusions OAB may occur in approximately 18% of SUI patients who undergo MUS surgery, and voiding dysfunctions with deteriorated voiding symptom and storage symptom may also occur. The deteriorated OAB was shown in 45% of SUI patients with OAB after the surgery.

Abstract
PURPOSE Patients in the intensive care unit (ICU) are usually at greater risk for acquiring urinary tract infections (UTIs). Few studies have focused on UTIs specifically acquired within the ICU. We studied the change in bacterial species causing UTIs in ICU admitted patients in 2001 and 2011. MATERIALS AND METHODS We reviewed the medical records of a total of 2,890 ICU patients who had undergone urine culture in 2001 and 2011 at the Yeouido and Bucheon St. Mary's hospitals. Changes in causative organisms and their antibiotic sensitivity between the years 2001 and 2011 were analyzed. RESULTS Escherichia coli (E. coli) was the most common organism in ICU-acquired UTIs in 2001 and 2011 in our study. The pathogens that significantly increased in 2011 compared to 2001 were Pseudomonas, and Klebsiella species (P < .05). In 2011 gram-negative organisms showed relatively higher sensitivities to amikacin, imipenem, and tazocin (72.0%, 77.5% and 76.1%, respectively), whereas they showed relatively lower sensitivities to third-generation cephalosporins and ciprofloxacin (55.2% and 45.0%, respectively). In 2011 gram-positive organisms showed high sensitivities to teicoplanin and vancomycin (91.1% and 87.9%, respectively), whereas they showed low sensitivities to ampicillin and ciprofloxacin (24.1% and 25.5%, respectively). The antibiotic resistance rate of Pseudomonas species was nearly doubles that of E. coli. CONCLUSION Infections caused by Pseudomonas and Klebsiella species were found to have increased significantly in 2011. Pseudomonas species had a significantly lower susceptibility to antibiotic sensitivity than other identified organisms.

Abstract
A 7-year-old boy was diagnosed with a recurrent embryonal rhabdomyosarcoma in the retroperitoneum. After resection of the mass, direct end-to-end anastomosis of the ureter was not possible owing to the length of the resected segment. Accordingly, we performed ureteral substitution by using the appendix to repair the ureteral defect.

Abstract
OBJECTIVE To investigate the effects of new herbal formula (KBMSI-2) on erectile dysfunction in streptozotocin (STZ)-induced diabetic rat model. METHODS Twenty four Sprague-Dawley male rats were randomly divided into three groups; control (n=8), diabetes model (n=8), diabetes + KBMSI-2 200 mg/kg treatment (n=8) groups. The diabetes induced groups received a single intraperitoneal injection of STZ. Distilled water was administered in the control and model groups. To investigate the penile erection, intracavernosal pressure (ICP) and intracavernosal pressure/mean arterial pressure (ICP/MAP) were recorded in all groups. Serial sections of the penis were used to perform Masson's trichrome stain. The expression of neuronal nitric oxide synthase (nNOS), endothelial NOS (eNOS) and cyclic guanosine monophosphate (cGMP) concentration in the isolated corpus cavernosum were analyzed by Western blotting. RESULTS Peak ICP/MAP ratio was increased in the KBMSI-2 treatment group compared with the model group (P<0.05). Masson's trichrome staining confirmed that the smooth muscle component was increased in the KBMSI-2 treatment group compared with the model group (P<0.05). The nNOS, eNOS and cGMP expression of KBMSI-2 200 mg/kg treatment group was increased compared with the model group (P<0.05). CONCLUSION This study showed that herbal formula of KBMSI-2 improved the erectile function by preserving the smooth muscle content and inhibiting the fibrosis of the corpus cavernosum in STZ-induced diabetic rat model.

Abstract
PURPOSE The aim of this study was to investigate the anti-inflammatory effects of a new herbal formula (WSY-1075) in a nonbacterial prostatitis rat model. MATERIALS AND METHODS Prostatitis was induced in male Wistar rats (n=32) by treatment with 17 beta-estradiol and dihydrotestosterone for 4 weeks. After the induction of prostatitis, the rats were randomly divided into one of four treatment groups: control (n=8), ciprofloxacin (n=8), WSY-1075 (100 mg/kg) (n=8), and WSY-1075 (400 mg/kg) (n=8). After 4 weeks of treatment, the prostatic proinflammatory cytokine (tumor necrosis factor-α, interleukin [IL]-6, and IL-8) levels and histological findings were noted. RESULTS The ciprofloxacin and WSY-1075 treatment groups showed significantly decreased proinflammatory cytokine levels compared with the control group. Histologically, treatment with ciprofloxacin and WSY-1075 significantly suppressed the severity of prostatitis lesions compared with those in the control group. No differences in the proinflammatory cytokine levels or histologic findings were observed with the dose dependent treatment of WSY-1075. CONCLUSIONS The new herbal formula, WSY-1075, showed effective anti-inflammatory activities in the prostate and may be useful for the clinical treatment of nonbacterial prostatitis. Our findings suggest that WSY-1075 has a beneficial effect on the prevention and treatment of nonbacterial prostatitis.

Abstract
Purpose: There are few studies about clinical courses following acute bacterial prostatitis (ABP). We evaluated the progression rates of chronic bacterial prostatitis (CBP) and inflammatory chronic pelvic pain syndrome (CPPS) after ABP treatment. Also evaluated the characteristics of the patients who developed CBP and inflammatory CPPS after ABP treatment. Methods: Total 437 patients compatible with a confirmed diagnosis of ABP from 5 urological centers between 2001 and 2010 were enrolled to study. We defined chronic infection (CI) as a progression to CBP and inflammatory CPPS after treatment of ABP in admission periods when followed up at 3 months or more. Results were analyzed between two groups: recovered without CI (group A, n=385) and developed to CI (group B, n=52). Results: Of the 437 ABP patients, 1.3% (6/437) progressed to CBP and 10.5% (46/437) progressed to inflammatory CPPS. The progression rate of CI was 11.8% (52/437). The patients who developed to CI were higher in alcohol consumption rate, diabetes, voiding symptoms, prior manipulation rate, enlarged prostate volume, catheterization history rate and short duration of antibiotic treatment (P<0.05). Conclusions: The identification and characterization of these factors may accelerate the development of preventive, diagnostic and therapeutic strategies for the treatment of CI from ABP.

Abstract
Purpose We evaluated adult patients with acute epididymitis to identify the frequency of actual sexual contacts and the causative organism, and compared clinical examinations, degrees of manifested symptoms, and radiological test results. Materials and Methods We reviewed the medical records of 65 patients older than 18 years presenting with acute epididymitis who had been treated between 2002 and 2011. Scrotal ultrasonography, urinalysis, and urine culture were performed to diagnose the acute epididymitis. Patients were divided into negative (n=45) and positive (n=20) urine culture groups. Then the latter groups were subdivided into a sexually transmitted organism (STO) culture group (n=13) and a non-STO (n=7) culture group. Data on any history of sexual contact, scrotal pain and tenderness, symptoms of urethritis (discharge, dysuria, urethral burning, or irritation), and lower urinary tract symptoms (dysuria, frequency, and urgency of urination) were obtained from all of the subjects. Results Patients in the positive urine culture group were significantly younger than those in the other group (p=0.224) and were more likely to have a history of sexual contact at least two weeks prior to onset of epididymitis (p=0.012). They had also a significantly enlarged epididymal head and significantly more severe complaints of pain or tenderness than those of latter group (p=0.348, p=0.288). However, the difference in these measures between the STO and non-STO group was not significant, except in the case of age (p=0.044). Conclusions Patients of the positive urine culture group with acute epididymitis were significantly younger and more sexually active than the others. They also had severe pain or tenderness and an enlarged epididymal head. There was a close association between clinical symptoms, a positive urine culture, and ultrasonographic findings.

Abstract
PURPOSE This study took a retrospective approach to investigate patients with catheter-associated urinary tract infection (CAUTI) over 2 years at a single hospital's intensive care unit (ICU) to identify meaningful risk factors and causative organisms. MATERIALS AND METHODS A retrograde analysis was performed on patients with indwelling catheters between January 2009 and December 2010 in Yeouido St. Mary Hospital medical and surgical ICU. CAUTI was defined as isolated bacterial growth of 100,000 colony-forming units or more either 48 hours after transfer to the ICU if a urinary catheter was placed before the transfer or 48 hours after insertion if the catheter was inserted in the ICU. Only the patients whose culture results were negative before ICU admission were included. RESULTS There were a total of 1,315 patients with indwelling urinary catheters in our hospital's medical and surgical ICU between January 2009 and December 2010. Of these patients, 241 had positive urine culture results, and 61 had CAUTI. Using multivariate logistic regression analysis, those with diabetes were 4.55 (p<0.001) times as likely to have occurrences of CAUTI than were those without and also had a 1.10-fold (p<0.01) longer duration of an indwelling catheter. Upon urine culture, among the 61 patients with CAUTI, Escherichia coli was the most common bacterium grown; it was identified in 24 patients (38.7%). CONCLUSIONS The factors and causative organisms contributing to the development of CAUTI in the management of ICU patients must be considered to prevent the occurrence of UTIs in this setting.

Abstract
PURPOSE We evaluated the differences in calculi characteristics and their prevalence according to the presence of lower urinary tract symptoms between adult patients examined at the Urology Department and those examined at the Health Promotion Center (HPC). MATERIALS AND METHODS The prevalence of prostatic calcification, characteristics of calculi (number, size, and location), and differences in lower urinary tract symptoms were compared and analyzed for 479 subjects who underwent transrectal ultrasonography at the HPC and the Urology Outpatients Department at our hospital from October 2009 to October 2010. RESULTS Of 479 subjects, 268 patients were examined at the HPC, and 211 were examined at the Urology Outpatients Department. Between the two groups, age, prostate-specific antigen levels, prostate volume transrectal ultrasonography, International Prostate Symptom Score (total, voiding, and storage), quality of life, and the prostatic calcification rate were significantly higher in the patients who visited the Urology Outpatients Department. The prevalence of prostatic calcification was 41.5% (199/479), with 36.1% (97/268) from the HPC and 48.3% (102/211) from the Urology Outpatients Department. When the characteristics of prostatic calcification were compared, there were no significant differences in the appearance, size, or location of the calculi between the two groups. CONCLUSIONS The prevalence of prostatic calcification was high in patients complaining of lower urinary tract symptoms; however, there were no significant differences in the characteristics of the calculi. This finding leads us to believe that prostatic calcification can aggravate lower urinary tract symptoms but does not result in differences according to the number, size, or appearance of the calculi.

Abstract
OBJECTIVE To survey cases of benign prostatic hyperplasia (BPH) among patients visiting urologists with lower urinary tract symptoms (LUTS) at general hospitals in Korea and to investigate treatment outcomes in current clinical practice. METHODS This was a multicenter, prospective study conducted in 18 urology centers in Korea. The symptoms of BPH were observed via the International Prostate Symptoms Score (IPSS), transrectal ultrasonography, uroflometry, prostate, specific, antigen, PSA) and postvoid residual volume at the baseline, 1 week, 4 weeks, 12 weeks, 24 weeks, and 52 weeks after initial evaluation. The patients were divided into three groups according to age (group I: 50-59; group II: 60-69; group III: 70 years or older). RESULTS Of the 1054 screened men, 966 were enrolled and 917 were diagnosed with BPH. Total IPSS and storage subscores were significantly higher in group III than in group II or I. By month 12, significant improvements on total IPSS and voiding subscores were demonstrated in group I over groups II and III (P = .02. 03, respectively). The incidence of dual combination therapy was significantly higher in the patients whose prostate volume was ≥30 mL and whose PSA was ≥1.5. CONCLUSION At the initial visit, patients with LUTS/BPH, especially those who were relatively young, visited urologic centers because of to voiding symptoms rather than storage symptoms. In contrast, elderly men who visited the urologic centers complained not only of voiding symptoms but also storage symptoms. However, at 12 months' follow up, all of the age groups showed improvement in both storage and voiding symptoms.

Abstract
Although tert-butyl hydroperoxide (t-BHP) is commonly used to induce oxidative stress, little is known about the time- or dose-dependence of its oxidative effects. In this study, we examined hepatotoxicity and oxidative stress in male rats at various times (0-24 h) after t-BHP (0, 0.2, 0.5, 1 or 3 mmol/kg, ip) treatment. Serum hepatotoxicity parameters were increased from 2 h following 1 mmol/kg t-BHP and reached their maximum values at 8 h. Plasma malondialdehyde levels were maximally elevated by 62% at 0.5 h and returned to control levels by 4 h. Hepatic glutathione levels were decreased between 0.5 and 2 h, and hepatic glutathione disulfide levels were increased at 2h. Interestingly, hepatic glutathione levels were increased at 24 h, which may be attributed to up-regulation of glutathione synthesis through induction of gamma-glutamylcysteine ligase expression. The elevation of hepatotoxic parameters and plasma MDA was observed from 0.5 to 1 mmol/kg t-BHP, respectively, in a dose-dependent manner. Considering that the maximal dose resulted in 20% lethality, 1 mmol/kg of t-BHP may be suitable for evaluating antioxidant activity of tested compounds. Our results provide essential information to characterize the t-BHP-induced oxidative stress and hepatotoxicity.

Abstract
PURPOSE To evaluate the effectiveness of 2 more core prostate biopsy protocol in detecting the prostate cancer (PCa) by comparing 10-core prostate biopsy with 12-core according to the prostate-specific antigen (PSA) level and the prostate volume. MATERIALS AND METHODS A total of 474 men with elevated serum levels of PSA between 2.5 and 20.0 ng/mL, regardless of abnormal finding on digital rectal examination and transrectal ultrasonography, received transrectal ultrasound-guided prostate biopsies. The patients were prospectively randomized to undergo 10-core (group 1, n = 351) or 12-core (group 2, n = 123) biopsy. The PCa detection rates were assessed and compared according to the serum level of PSA and prostate volume. RESULTS Of 474 men, 128 (27.0%) were diagnosed with PCa. The PCa detection rates of 10-core and 12-core biopsies were 26.4% and 28.4%, respectively (P = .378). There was no difference in cancer detection rates according to PSA level in both groups. Comparing the cancer detection rates according to the prostate volume (< 40 mL and ≥ 40 mL), the patients with prostate volume ≥ 40 mL showed higher cancer detection rates in 12-core biopsy group (26.9%) compared with 10-core biopsy group (16.4%) (P < .05). CONCLUSION The overall cancer detection rates showed no differences in both groups. But the 12-core biopsy was a more efficient method in men with a prostate volume of ≥ 40 mL, compared to the 10-core biopsy.

Abstract
Purpose Transrectal ultrasound-guided prostate biopsy is the procedure of choice for diagnosing prostate cancer. We compared with pain-relieving effect of acetaminophen, a known drug for enhancing the pain-relieving effect of tramadol, and eutectic mixture of local anesthetics (EMLA), a local anesthetic agent, with that of the conventional periprostatic nerve block method. Materials and Methods This was a prospective, randomized, single-blinded study. A total of 430 patients were randomly assigned to three groups. Group 1 received a periprostatic nerve block with 1% lidocaine, group 2 received acetaminophen 650 mg, and group 3 received EMLA cream for pain control. All patients were given 50 mg of tramadol intravenously 30 minutes before the procedure. At 3 hours after completion of the procedure, the patients were asked to grade their pain on a horizontal visual analogue scale (VAS). The patients were also asked whether they were willing to undergo future biopsy if required. Results There were no significant differences between the three groups in terms of age, prostate-specific antigen, prostate size, or numbers of biopsy cores. The pain scores for groups 2 and group 3, which were 3.47±1.92 and 3.50±1.36, respectively, were similar and were significantly lower than that of group 1, which was 5.24±2.07. Conclusions Acetaminophen and EMLA cream with intravenous injection of tramadol are safe, easy, and effective methods of controlling pain during the procedure. These methods were more effective for pain relief than was the conventional periprostatic nerve block method.

Abstract
PURPOSE Prostate cancer foci have a characteristic feature in magnetic resonance imaging (MRI). We aimed to assess the clinical value of MRI before prostate biopsy in prostate cancer detection. MATERIALS AND METHODS From March 2009 to June 2010, 154 patients were enrolled in this study. A total of 51 patients with a clinical suspicion of prostate cancer underwent prostate MRI by a 3T scanner before transrectal ultrasound (TRUS)-guided biopsies. A total of 103 patients with a clinical suspicion of prostate cancer underwent prostate MRI after biopsies. The sensitivity, specificity, and positive predictive value (PPV) were evaluated. In addition, tumor location of pathologic findings and ADC mapping on MRI were matched and compared. RESULTS The sensitivity of MRI before and after biopsy was 84.8% and 92.4%, respectively. The PPV of MRI before and after biopsy was 75.7% and 92.4%, respectively. The MRI location match percentage before and after biopsy was 89.3% and 94.1%, respectively. CONCLUSIONS Compared with other previous reports, our results show that the prostate cancer detection sensitivity of MRI is on the rise. Furthermore, MRI before prostate biopsy can provide more information by which to identify prostate cancer during prostate biopsy and thus reduce the false-negative rate.

Abstract
The antibiotic treatment rate of chronic bacterial prostatitis (CBP) is low, and long-term administration can result in adverse events and bacterial resistance. For these reasons, a new preventive modality, which can replace traditional antibiotic therapy, is required. To evaluate the preventive effect of selenium on CBP, the pre-treatments were divided into four groups, administered for 4 weeks, as follows: (1) control, (2) ciprofloxacin, (3) selenium, and (4) ciprofloxacin and selenium. Then, drip infusion of a bacterial suspension (Escherichia coli Z17, O2:K1; H-) into the prostatic urethra of Wistar rats was conducted to induce CBP. In 4 weeks, the results of microbiological culture of prostate and urine samples as well as histological findings of the prostate in each group were analyzed. Selenium decreased bacterial infection significantly; the decrease in infiltration rate of inflammatory cells into prostate tissues in the selenium group was similar to that in the control group. The effect of hindering bacterial infection on prostate tissue was greater in the group administered both selenium and an antibiotic than in other groups given only one of the agents. Although the findings of this study suggest that selenium can have a preventive effect against the occurrence of CBP, methods to prevent CBP are still controversial.

Abstract
PURPOSE We examined changes in the clinicopathologic characteristics of renal cell carcinoma (RCC) in the past 25 years and aimed to obtain indicators for its diagnosis and treatment. MATERIALS AND METHODS The medical records of 563 patients with confirmed primary RCC after surgical treatment from 1985 to 2010 at Seoul St. Mary's Hospital were retrospectively reviewed. Patient and tumor characteristics were compared over 3 time periods (period 1: 1985-1994, period 2: 1995-2004, period 3: 2005-2010). RESULTS Period 1 included 65 patients, period 2 included 183 patients, and period 3 included 315 patients, showing an exponential growth in the number of patients. Frequency was highest in the late 50s age group. The review of clinical symptoms showed that incidental diagnosis increased significantly. The tumor size at diagnosis gradually decreased and the proportion of small tumors less than 4 cm increased remarkably. Concerning tumor spread, organ-confined tumors (T(1-2)N(0)M(0)) increased and distant metastasis decreased. Histologically, the clear cell type made up the greatest proportion, about 90% in each period, but subtypes besides the clear cell type increased over the study period. The rate of nephron-sparing surgery increased, and exophytic masses were the most common. CONCLUSIONS Our review of the recent 25 year's worth of data on RCC from Seoul St. Mary's Hospital showed that the incidental diagnosis of RCC increased over the study period in accordance with the development of screening tests. Tumor size decreased in accordance with the progress in imaging modalities. In the future, multicenter research will be needed to analyze the characteristics of whole renal cancer in Korea.

Abstract
Chronic bacterial prostatitis (CBP) is one of the most common relapsing urinary tract infection (UTI) in males. Catechin, an extract of green tea, is known to have anti-inflammatory and antimicrobial effects against various bacteria. However, catechin can be easily degenerated during digestion, and this may result in decreased absorption into the body. Nanocatechin is catechin coated with hydroxypropyl methyl cellulose by nanotechnology. It reduces degeneration during digestion and enhances absorption of catechin into the body. We evaluated the anti-inflammatory and antimicrobial effect of nanocatechin on CBP and also analyzed plasma concentration of catechins to evaluate absorptivity in an animal model. Forty rats demonstrating CBP were randomly divided into four groups: control, ciprofloxacin, catechin, and nanocatechin. After treatment, the results of microbiological culture of prostate and urine samples as well as histological findings of the prostate in each group were analyzed. Plasma concentration of catechins in catechin and nanocatechin groups was compared. The use of ciprofloxacin, catechin, and nanocatechin showed statistically significant decrease in bacterial growth and improvement in prostatic inflammation compared with the control group. The nanocatechin group showed statistically significant decrease in bacterial growth and improvement in prostatic inflammation compared with the catechin group. Plasma concentrations of epicatechin, gallocatechin gallate, and epigallocatechin gallate were significantly higher in the nanocatechin group than those in the catechin group. These results suggest that nanocatechin has better antimicrobial and anti-inflammatory effects on rat CBP than catechin due to higher absorption into the body.

Abstract
The aim of this study was to examine the efficacy of in ovo prime-boost vaccination against infectious bursal disease virus (IBDV) using a DNA vaccine to prime in ovo followed by a killed-vaccine boost post hatching. In addition, the adjuvant effects of plasmid-encoded chicken interleukin-2 and chicken interferon-γ were tested in conjunction with the vaccine. A plasmid DNA vaccine (pcDNA-VP243) encoding the VP2, VP4, and VP3 proteins of the very virulent IBDV (vvIBDV) SH/92 strain was injected into the amniotic sac alone or in combination with a plasmid encoding chicken IL-2 (ChIL-2) or chicken IFN-γ (ChIFN-γ) at embryonation day 18, followed by an intramuscular injection of a commercial killed IBD vaccine at 1 week of age. The chickens were orally challenged with the vvIBDV SH/92 strain at 3 weeks of age and observed for 10 days. In ovo DNA immunization followed by a killed-vaccine boost provided significantly better immunity than the other options. No mortality was observed in this group after a challenge with the vvIBDV. The prime-boost strategy was moderately effective against bursal damage, which was measured by the bursa weight/body weight ratio, the presence of IBDV RNA, and the bursal lesion score. In ovo DNA vaccination with no boost did not provide sufficient immunity, and the addition of ChIL-2 or ChIFN-γ did not enhance protective immunity. In the ConA-induced lymphocyte proliferation assay of peripheral blood lymphocyte collected 10 days post-challenge, there was greater proliferation responses in the DNA vaccine plus boost and DNA vaccine with ChIL-2 plus boost groups compared to the other groups. These findings suggest that priming with DNA vaccine and boosting with killed vaccine is an effective strategy for protecting chickens against vvIBDV.

Abstract
Over the 42 month period from January 2003 to June 2006, a total of 2,952 canine biopsy specimens were received from the Veterinary Medical Teaching Hospital of Seoul National University and from veterinary practitioners across the nation. Out of these, 748 (25.34%) cases were diagnosed as canine cutaneous tumors in the Department of Veterinary Pathology, College of Veterinary Medicine, Seoul National University, Korea. Thirty-eight different types of cutaneous tumors were identified and categorized into epithelial and melanocytic tumors (56.95%), mesenchymal tumors (38.90%), and hematopoietic tumors (4.14%) located in the skin. Among these, 69.25% were benign and 30.74% were malignant. The top ten most frequently diagnosed cutaneous tumors were epidermal and follicular cysts (12.70%), lipoma (11.36%), mast cell tumors (8.82%), cutaneous histiocytoma (7.49%), basal cell tumors (6.82%), sebaceous gland adenoma (6.68%), sebaceous gland hyperplasia (5.08%), hepatoid gland adenoma (3.61%), apocrine adenocarcinoma (3.07%), and fibroma (2.81%), in order of prevalence. They comprised 68.45% of all cutaneous tumors. These top ten cutaneous tumors were distributed on the trunk (30.08%), head and neck (20.9%), extremities (19.14%), anal and perianal area (8.59%), and tail (3.91%). The age of the dogs with the ten most frequent tumors had a mean age of 8.3 years, with a range of 2 months to 19 years. When all types of tumors were considered together in the entire population, there was no difference in incidence according to sex.
