ABSTRACT: Aim: To compare the improvement in erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) as well as safety of tadalafil dosed at 20 mg on-demand and 5 mg once daily among ED patients. Materials and methods: A total of 194 ED patients visited between March 2010 and June 2011 were recruited. Out of 194 individuals, 168 (86.6%) met inclusion criteria after completing the two-week screening period (V0). The Patients were randomly allocated into two groups: (i) 20 mg of tadalafil as needed (Group 1: n = 84, 50.0%) and (ii) 5 mg of tadalafil once daily (Group 2: n = 84, 50.0%). Blood pressure (BP), heart rate (HR) and the five-item version of the International Index of Erectile Function (IIEF-5) were assessed immediately before initiation of treatment (V1) and after four (V2) and twelve weeks of treatment (V3). In men with an IPSS of ≥ 8 at V1, IPSS, maximal flow rate (Qmax) and post-void residual volume (PVR) were also assessed. Results: Of the 168 patients, 134 (79.8%; Group 1: n = 68, 81.0%; Group 2: n = 66, 78.6%) patients completed the trial. IIEF-5 improved in both groups, and the mean change was larger in Group 2 at V3 (4.9 ± 4.2 vs. 6.5 ± 4.5; p = 0.032) Similarly, though IPSS (with ≥ 8, n = 88, 65.7%; Group 1: n = 44, 64.7%; Group 2: n = 44, 66.7%) improved in both groups, the mean change was larger in Group 2 at V3 (-2.8 ± 4.3 vs. -4.8 ± 4.1; p = 0.026). Qmax and PVR did not differ significantly in either group. Conclusions: Once daily tadalafil was more efficacious in treating both ED and LUTS than on-demand dosing. However, no differences were observed between the two dosing schedules with regard to the improvement in LUTS when stratified by improvement in ED. The side effects were insignificant for both dosing schedules.

ABSTRACT: This study was conducted to assess outcomes (according to patency) of vasectomy reversal (VR) in qualified patients with postvasectomy pain syndrome (PVPS). A total of 32 patients with PVPS undergoing VR between January 2000 and May 2010 were examined retrospectively. Of these, 68.8% (22/32) completed a study questionnaire, either onsite at the outpatient clinic or via telephone interview. Preoperative clinical findings, preoperative and postoperative visual analogue scale (VAS) pain scores, patency and pregnancy rate and overall patient satisfaction were analyzed. For the latter, a four-point rating of (1) cure, (2) improvement, (3) no change or (4) recurrence was used. The mean age was 45.09±4.42 years and the mean period of follow-up was 3.22 years (0.74-7.41). Patency rates were 68.2% (15/22) and pregnancy rates were 36.4% (8/22). The mean VAS was 6.64±1.00 preoperatively and 1.14±0.71 postoperatively (P<0.001). The difference in the mean preoperative and postoperative VAS was 6.00±1.25 (4-8) in the patency group and 4.43±0.98 (3-6) in the no patency group (P=0.011). A significant difference in procedural satisfaction with surgical outcome was observed between patency and no patency groups (P=0.014). In conclusion, in PVPS patients requiring VR, a significant difference was observed between the patency and no patency groups in terms of pain reduction and the degree of patient procedural satisfaction.

ABSTRACT: The low efficiency of conventional therapies in achieving long-term survival of lung cancer patients calls for development of novel options. Revisiting of aerosol gene delivery may provide an alternative for safe and effective treatment for lung cancer. In this study, imidazole ring-containing urocanic acid-modified chitosan (UAC) designed in the previous study was used as a gene carrier. The potential effects of phosphatase and tensin homolog deleted on chromosome 10 (PTEN) on Akt-related signals and cell cycle regulation were evaluated. Aerosols of UAC-PTEN were delivered into K-ras(LA1) lung cancer model mice through the nose-only inhalation system twice a week for total 4 weeks. Delivered PTEN suppressed lung tumor development significantly through nuclear complex formation between PTEN and p53, suppressing Akt-related signals as well as cell cycle regulation. Together, our results suggest that aerosol delivery of UAC-PTEN may be compatible with noninvasive in vivo gene therapy.

ABSTRACT: The long-term survival of lung cancer patients treated with conventional therapies remains poor and therefore the need for novel approaches remains high. This has led to the re-emergence of aerosol delivery as a therapeutic intervention. In this study, glucosylated polyethylenimine (GPEI) was used as carrier to investigate programmed cell death 4 (PDCD4) and PDCD4 mutant (D418A), an eIF4A-binding mutant, on PDCD4-related signaling and activator protein-1 (AP-1) activity in the lungs of AP-1 luciferase reporter mice. After confirming the efficiency of GPEI as a carrier in lungs, the effects of aerosol-delivered PDCD4 were investigated in AP-1 luciferase reporter mice. Aerosol delivery of GPEI/PDCD4 through a nose-only inhalation facilitated the apoptosis of lungs whereas aerosol PDCD4 mutant did not. Also, such aerosol delivery regulated proteins relevant to cell-cycle control and suppressed AP-1 activity. Results obtained by western blot analysis, immunohistochemistry, luciferase assay and deoxynucleotidyl-transferase-mediated nick end labeling study suggest that combined actions such as facilitating apoptosis, controlling cell cycle and suppression of AP-1 activity by PDCD4 may provide useful tool for designing lung tumor prevention and treatment by which PDCD4 functions as a transformation suppressor in the future.

ABSTRACT: Chitosan has been investigated as a non-viral vector because it has several advantages such as biocompatibility, biodegradability and low toxicity with high cationic potential. However, the low specificity and low transfection efficiency of chitosan need to be solved prior to clinical application. In this paper, we focused on the galactose or mannose ligand modification of chitosan for enhancement of cell specificity and transfection efficiency via receptor-mediated endocytosis in vitro and in vivo.

ABSTRACT: Lung cancer has emerged as a leading cause of cancer death in the world; however, most of the current conventional therapies are not sufficiently effective in altering the progression of disease. Therefore, development of novel treatment approaches is needed. Although several genes and methods have been used for cancer gene therapy, a number of problems such as specificity, efficacy and toxicity reduce their application. This has led to re-emergence of aerosol gene delivery as a noninvasive method for lung cancer treatment. In this study, nano-sized glucosylated polyethyleneimine (GPEI) was used as a gene delivery carrier to investigate the effects of Akt wild type (WT) and kinase deficient (KD) on Akt-related signaling pathways and protein translation in the lungs of CMV- LucR-cMyc-IRES-LucF dual reporter mice. These mice are a powerful tool for the discrimination between cap-dependent/-independent protein translation. Aerosols containing self-assembled nano-sized GPEI/Akt WT or GPEI/Akt KD were delivered into the lungs of reporter mice through nose-only-inhalation-chamber with the aid of nebulizer. Aerosol delivery of Akt WT caused the increase of protein expression levels of Akt-related signals, whereas aerosol delivery of Akt KD did not. Furthermore, dual luciferase activity assay showed that aerosol delivery of Akt WT enhanced cap-dependent protein translation, whereas a reduction in cap-dependent protein translation by Akt KD was observed. Our results clearly showed that targeting Akt may be a good strategy for prevention as well as treatment of lung cancer. These studies suggest that our aerosol delivery is compatible for in vivo gene delivery which could be used as a noninvasive gene therapy in the future.

ABSTRACT: Extracellular matrix (ECM) plays important roles in tissue engineering because cellular growth and differentiation, in the two-dimensional cell culture as well as in the three-dimensional space of the developing organism, require ECM with which the cells can interact. Especially, the bioartificial liver-assist device or regeneration of the liver-tissue substitutes for liver tissue engineering requires a suitable ECM for hepatocyte culture because hepatocytes are anchorage-dependent cells and are highly sensitive to the ECM milieu for the maintenance of their viability and differentiated functions. Galactose-carrying synthetic ECMs derived from synthetic polymers and natural polymers bind hepatocytes through a receptor-mediated mechanism, resulting in enhanced hepatocyte functions. Attachment and functions of hepatocytes were affected by physico-chemical properties including ECM geometry as well as the type, density and orientation of galactose. Also, cellular environment, medium composition and dynamic culture system influenced liver-specific functions of hepatocytes beside ECM.

ABSTRACT: A 45-year-old South-Korean man presented with abdominal distension, progressive paresthesia and motor weakness of both lower extremities. Our case was identified as polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin change (POEMS) syndrome based on diagnostic criteria. Circulating M components of POEMS syndrome consist mainly of IgG or IgA-lambda and rarely IgM-lambda, IgG-kappa or isolated light chains. In this case, the M-band on serum protein electrophoresis and isolated IgA heavy chain on serum immunofixation electrophoresis were demonstrated, but there was no abnormal light chain. We suggest that this case may be associated with a pattern of abnormal secretion of monoclonal protein or a coincidence of a heavy chain disease in POEMS syndrome, even though the latter possibility may be very rare.

ABSTRACT: To determine the distribution of HLA-DR type and FcgammaRIIa/IIIa polymorphisms, and to analyse the combined effects of these genes for susceptibility in Korean systemic lupus erythematosus (SLE) patients.
A total of 299 SLE patients meeting 1982 ACR criteria and 144 Korean disease-free controls were enrolled. Genotyping for the FcgammaRIIa 131 R/H and FcgammaRIIIa 176 F/V was performed by polymerase chain reaction (PCR) of genomic DNA using allele-specific primers. HLA-DRB1 typing was performed by the PCR-SSOP method.
There was significant skewing in the distribution of the three FcgammaRIIa genotypes between the SLE patients and the controls [P = 0.002 for R/R131 vs R/H131 and H/H131, relative risk (RR) 2.6 (95% CI 1.3-5.2)], but not in FcgammaRIIIa genotypes. HLA-DRB1*15 allele was significantly more prevalent among SLE patients than the control population [P < 0.02, RR = 1.7 (1.1-2.6)]. HLA-DRB1 genotypes or allele frequencies of the SLE patients with nephritis did not differ significantly from those of the SLE patients without nephritis. We analysed the combined effects of the two candidate genes on SLE susceptibility. HLA-DRB1*15 allele was a significant predictor of SLE in individuals who were not homozygous for FcgammaRIIa-R/R131 [RR = 2.1 (1.2-3.7), P < 0.008], and the FcgammaRIIa-R/R131 genotype vice versa [RR = 5.3 (1.9-15.4), P < 0.001]. However, an additive or synergistic effect of both susceptible genes on relative risk for SLE was not evident.
Our results suggest that FcgammaRIIa-R/R131 homozygote and HLA-DRB1*15 allele are independent risk factors in Korean SLE patients without additive or synergistic effects.

ABSTRACT: The objectives of this study were to assess the quality of marital life (QML) in patients with spondyloarthropathy (SpA) in Korea and to identify possible gender differences in QML in patients with SpA. This was a case-control study at the outpatient unit of a tertiary care medical centre. Subjects were the patient group, composed of 47 married patients with SpA, and a comparison group composed of 47 healthy married adults with similar demographic characteristics. QML was measured using the Marital Satisfaction Inventory, Revised. As a result, QML was similar for both the male patients and the healthy men. However, the female patients had higher scores on the global distress scale (59.8 +/- 6.3 vs. 53.8 +/- 5.6, P=0.021) and the aggression scale (50.5 +/- 7.9 vs. 44.3 +/- 5.4, P=0.016) than the female comparison group. At the same time, the female patients demonstrated higher scores on the global distress scale (59.8 +/- 6.3 vs. 54.7 +/- 7.2, P=0.035) than the male patients. In conclusion, QML in Korean males with SpA was not greatly different from that of the male comparison group. However, QML in the female patients was characterised by higher global distress and a higher probability of aggression from their partner, but no significant sexual dissatisfaction.

ABSTRACT: Dual-labeled galactosylated chitosan-graft-poly(ethylene glycol) (PEG) (GCP)/DNA complexes were prepared and their hepatocyte-specific delivery and cellular distribution were investigated by confocal laser scanning microscopy (CLSM). The complexes were transfected into hepatocyte through specific interaction of galactose moiety of the GCP and asialoglycoprotein receptors (ASGPR) of the hepatocytes. The GCP/DNA complexes taken up by the hepatocytes were rapidly released into the cytoplasm, but nuclear trafficking of the released complexes was slow and rate-limiting process. The more efficient transfection of the complex occurred in the human-derived HepG2 cells than in primary hepatocytes.

ABSTRACT: Systemic lupus erythematosus (SLE) is an inflammatory multisystem disease of unknown etiology with immunologic aberrations. Many studies have shown that genetic and environmental factors are implicated in the development of SLE. Angiotensin-converting enzyme (ACE) affects various immune phenomena through the renin-angiotensin and kallikrein-kininogen systems by creating angiotensin II and inactivating bradykinin. We investigated the correlation between insertion/ deletion polymorphism of the ACE gene and the clinical manifestations of SLE, especially vascular involvement and lupus nephritis. Two-hundred and eleven Korean patients fulfilling the ACR criteria and 114 healthy subjects were enrolled. The ACE genotype was determined by polymerase chain reaction using genomic DNA from peripheral blood. The nephritis patients were classified by the WHO classification. In addition, the activity and chronicity index were used to assess the severity of renal involvement. We evaluated vascular involvement by the presence or absence of hypertension, Raynaud's phenomenon, livedo reticularis, antineutrophil cytoplasmic antibody and the SLICC/ACR Damage Index. The gene frequency of ACE gene polymorphism was as follows: II 39 vs 34%, ID 41 vs 50%, DD 20 vs 16% in SLE patients and controls, respectively. There was no difference in genotype frequency between both groups. There were no significant differences between the distribution of ACE gene genotypes and lupus nephritis and its related parameters, including WHO classification, activity index, chronicity index, renal dysfunction and amount of 24 h urinary protein. The ACE genotypes and alleles did not affect the presence of vascular manifestations evaluated, but the frequency of DD genotype was significantly low in SLE patients with Raynaud's phenomenon compared to those without Raynaud's phenomenon (P = 0.002 for ACE ID vs DD and II, OR 2.7, 95% CI 1.43-5.09; P=0.023 for ACE DD vs ID and II, OR 0.33, 95% CI 0.12-0.89). Also skewing from DD to II genotype was noted in patients with anti-Sm antibody compared to those without anti-Sm antibody (P = 0.025 for ACE DD vs ID and II, OR 0.21, 95% CI 0.05-0.93). The onset age of serositis was older in patients with the ID genotype than the others (ID= 34.5+/-10.8, II + DD = 25.6+/-10.2, P= 0.002). Also the onset age of malar rash was older in patients with II genotype than the others (II=26.7+/-8.4, ID+DD=21.3+/-9.0; P=0.021). The patients with I allele showed a significantly higher frequency of serositis (P = 0.022). Taken together, the I/D polymorphisms of ACE gene did not affect susceptibility of SLE, lupus nephritis and the vascular manifestations, including Raynaud's phenomenon, in Korean SLE patients, although the DD genotype was negatively associated with Raynaud's phenomenon among SLE patients. However, it would be valuable to evaluate the role of other genes potentially related to vascular events, such as endothelin, nitric oxide or angiotensin II receptor as well as ACE gene.

ABSTRACT: Our aims were to translate WOMAC and Lequesne osteoarthritis (OA) indices into Korean (KWOMAC, KLequesne) and confirm their reliability, validity, and responsiveness.
The WOMAC and Lequesne indices were translated into Korean by three translators and translated back into English by three different translators. Fifty consecutive patients with OA were asked to rate the comprehensibility of the questions on a 4-point scale. The comprehensibility (responding with 'good' and 'very good') ranged from 78% to 99%. Test-retest was performed in another 47 patients with knee OA. The final 53 patients with knee OA, within the context of a clinical trial of two non-steroidal antiinflammatory drugs for 4 weeks, were studied to assess the internal consistency, construct validity, and responsiveness of the Korean versions.
The test-retest reliability of the KWOMAC 3 subscales and the KLequesne yielded intraclass correlation coefficients of 0.79-0.89 and 0.87. The Cronbach standardized alphas were 0.81-0.96 and 0.75, respectively. For the construct validity, the correlation coefficients of both the KWOMAC subscales and the KLequesne with patient pain assessment and patient global assessment were between 0.30 and 0.70 and the KWOMAC subscales correlated with the KLequesne (0.41-0.55). For responsiveness, the KWOMAC and KLequesne scores significantly improved by 4-week post-treatment compared with pre-treatment; effect size values were between 0.41 and 0.69 for the KWOMAC subscales and 0.70 for the KLequesne; and the relative efficiency values of the KWOMAC subscales vs the KLequesne were between 0.87 and 0.90.
The reliability, validity, and responsiveness of the KWOMAC and the KLequesne are confirmed.

ABSTRACT: This study was performed to investigate whether peroxisome proliterator-activated receptor-gamma (PPAR-gamma) exerted an anti-inflammatory effect on rheumatoid synovial cells and inhibited dysregulated proliferation. The expression of PPAR-gamma mRNA in cultured human synoviocytes and THP-1 cells was analysed by RT-PCR. PPAR-gamma was expressed in normal, osteoarthritis (OA), rheumatoid arthritis (RA) synovial cells as well as a human monocytic cell line, THP-1. In RA and OA synoviocytes, the induction of inflammatory cytokine mRNA expression such as TNF-alpha and IL-1beta was significantly inhibited by the natural PPAR-gamma agonist, 15 deoxy-Delta(12,14)prostaglandin J(2)(15d-PGJ(2)). The effect of PPAR-gamma on the nuclear factor (NF)-kappaB activity was tested by electrophoretic mobility shift assay (EMSA). Both troglitazone and 15d-PGJ(2)markedly inhibited TNF-alpha-induced NF-kappaB activation at 30 microM. However, PPAR-gamma agonist neither reduced proliferation nor induced apoptosis in RA synoviocytes when measured by XTT assay and fluorescence activated cell sorter (FACS) analysis. In contrast, it induced apoptosis in a dose-dependent manner in THP-1 cells and augmented TNF-related apoptosis-inducing ligand (TRAIL)-induced apoptosis as well. In conclusion, these data demonstrate that PPAR-gamma is expressed in human synoviocytes and THP-1 cells, and the PPAR-gamma activation inhibits expression of inflammatory cytokines in RA synoviocytes. Furthermore, PPAR-gamma activation induces apoptosis by itself and augments TRAIL/Apo2L-induced apoptosis in THP-1 cells. These results suggest that PPAR-gamma agonists may provide a new therapeutic approach for RA.

ABSTRACT: Lactobionic acid bearing galactose group was coupled with chitosan for liver specificity, and poly(ethylene glycol) (PEG) was grafted to galactosylated chitosan (GC) for stability in water and enhanced cell permeability. Complex formation of galactosylated chitosan-graft-PEG (GCP)/DNA complexes was confirmed by agarose gel electrophoresis. Compared to GC/DNA complex, the stability of GCP/DNA complex could be enhanced. Particle sizes of GCP/DNA complexes decreased as the charge ratio of GCP to DNA increased and had a minimum value around 27 nm at the charge ratio of 5. Conformational change of DNA did not occur after complex formation with GCP compared to conformation of DNA itself. GCP/DNA complexes were only transfected into Hep G2 having asialoglycoprotein receptors (ASGR), indicative of specific interaction of ASGR on cells and galactose ligands on GCP.

ABSTRACT: Ankylosing spondylitis (AS) is characterised by its effects on the axial skeleton. The cervical spine is also vulnerable to the disease process. Our aim was to determine the frequency of radiologic changes to the cervical spine and their correlation with clinical variables. We also used the Bath Ankylosing Spondylitis Radiology Index (BASRI) system, which is one of the reliable scoring systems of radiography, to score the global radiologic changes to the cervical and lumbar spine and the hip joints in our AS cohort. There were 181 patients with anteroposterior and lateral full-flexion views on radiography of the cervical spine here included in the study. A radiologist examined the radiologic changes to all anatomical compartments of the cervical spine in detail and graded them according to the BASRI system. We used the clinical and demographic data of our AS cohort to determine their relation to the radiographic changes. Eighty-eight patients (48.6%) showed radiological changes to the cervical spine; to the discovertebral joint 35.9%; the apophyseal joint 26.0%; atlantoaxial articulation 22.1% (atlantoaxial subluxation 13.8%); the costovertebral joint 18.2%; and to the posterior ligamentous attachment 11.6%. Using the BASRI system, 73 patients (40.3%) showed radiologic changes to the cervical spine and were graded as score 1 (1.7%), 2 (22.7%), 3 (6.6%) or 4 (9.4%). Among those graded as normal by the BASRI system, 17 showed some changes the cervical spine, such as atlantoaxial joint subluxation or narrowing, and severe osteoporosis with no other radiographic changes. Current age, disease duration, inflammatory back pain and cervical symptoms were associated with the radiographic changes to the cervical spine. The BASRI-cervical spine score correlated with the BASRI-lumbar spine and hip joint score, sacroiliitis, disease duration, and duration of inflammatory back pain and cervical symptoms. Our data suggest that radiographic changes to the cervical spine are frequent in AS, and can be predicted in the patients with old age, long duration of disease and inflammatory back pain, and cervical symptoms. Also, the BASRI scoring system showed similar results as a detailed assessment of the cervical spine in our study.

ABSTRACT: Evans' syndrome is characterised by the simultaneous or sequential occurrence of Coombs'-positive haemolytic anaemia (AIHA) and immune thrombocytopenia without underlying aetiology. It has been found to be associated with collagen vascular diseases, especially systemic lupus erythematosus (SLE) and scleroderma. However, Evans' syndrome with dermatomyositis is very rare. A 59-year-old woman, who had been taking high-dose prednisolone for a month and cyclosporin for 10 days for dermatomyositis, developed purpura on the left popliteal fossa. The platelet and haemoglobin levels decreased to 77,000/mm3 and 9.8 g/dl, respectively. Antiplatelet antibody was positive. Thrombocytopenia responded to intravenous immunoglobulin (IVIG) for a short time, but further decreased in a week. Her blood film showed features of haemolytic anaemia. Laboratory findings showed reticulocytosis and a positive direct Coombs' test. Bone marrow examination showed a mild hyperplasia of erythroid precursors and megakaryocytes. The patient was successfully treated with cyclophosphamide in addition to oral prednisolone. AIHA in connective tissue disease may develop gradually and show a benign clinical course in most patients. Therefore, we suggest that patients with dermatomyositis and anaemia should always be checked for haemolysis if there is no other explanation.

ABSTRACT: We report a 25-year-old Korean woman with Adult onset Still's disease (AOSD) presented with renal amyloidosis, which had developed four years after disease onset. We successfully treated her with prednisolone, colchicine and cyclophosphamide. A review of the literature uncovered about 10 cases, most of which were treated by various regimens that resulted in poor outcomes. Renal amyloidosis should be suspected in patients with AOSD who have unexplained proteinuria. Although the mechanism of renal amyloid deposition is not well known, earlier histopathologic diagnosis and choice of regimen may affect prognosis.
