In this study, we aimed to investigate the prevalence and perception of premature ejaculation （PE） in young and middle-aged Korean men. The study was conducted using an Internet-assisted questionnaire. A total of 2 037 Korean male adults, aged 20 years or older, were randomly sampled based on age and residency. The questionnaire developed by the PE Study Group of the Korean Andrological Society includes four categories （overall sexual function, symptoms, distress and treatment） with a total of 16 questions. For each question, symptoms were evaluated by a scale ranging from 0 to 10. Intravaginal ejaculation latency time was ‘5-10 min＇ in 38.6%, followed by ‘longer than 10 min＇ in 2919%, ‘2-5 min＇ in 23.6%, ‘1-2 min＇ in 5.4% and ‘shorter than 1 min＇ in 2.5%. In our series, 27.5% of respondents reported having PE. Control over ejaculation within a recent 3-month period was 6.2 points on average. Respondent complaints of PE-related stress averaged 7.1 points and stress-related complaints from sexual partners averaged 7.1 points. The effect of PE on sexual life was 6.8 points. Of the respondents determined as having PE, 42.6% responded that they were inclined to receive treatment. Results from this study suggest that the prevalence of PE diagnosed by the respondent on his own was approximately 27.5% in young and middle-aged men in Korea. PE-related stress had a significant effect on the stress, sexual activity and quality of life of the respondent and his sexual partner.

A Case of Secondary Iris Cyst AfterPupilloplasty

Open Journal of Ophthalmology 2013年第1期3卷 13-15页

作者： Ja Young Lee Sun woong kim Eun Suk Koh Jee Ho Chang Department of Ophthalmology College of Medicine Soonchunhyang University Bucheon Korea Department of Ophthalmology Hando Hospital Ansan Korea Department of Pathology College of Medicine Soonchunhyang University Bucheon Korea

Purpose: To investigate the pathogenesis of a secondary iris cyst with an immunohistochemical method. Methods: Single observational case report. A pathologic specimen was obtained from a 5-year-old girl who was found to have a secondary iris cyst. She had a history of previous penetrating ocular trauma and subsequent cataract surgery and pupilloplasty. Immunohistochemical staining with cytokeratin (CK) 19 and CK3 was used. Results: After immunohistochemical staining, the inner wall showed positive staining for CK19, which is specific for limbal, peripheral cornea and conjunctival epithelium, and negative staining for CK3, which is specific for corneal epithelium. Conclusions: With the aid of immunohistochemical analysis, a conjunctival epithelial origin was indicated, and pupilloplasty was identified as the causal event of the iris cyst while the possibility of primary iris cyst was ruled out.

To evaluate patient preferences for sildenafil citrate or tadalafil （PDE-5 inhibitors available for the treatment of erectile dysfunction [ED]） and assess potential reasons for these preferences. Methods： This open-label study was conducted on Korean men taking sildenafil, at least 6 weeks prior to study entry, for ED. Following screening, patients continued sildenafil treatment for 4 weeks, then after a 1-week washout period, switched to tadalafil for 8 weeks. Patients then continued with their treatment of choice during an extension phase. Psychosocial factors （time concern, spontaneity, sexual self-confidence） were evaluated using Psychological and Interpersonal Relation- ship Scales （PAIRS）, while timing of dose to sexual attempt patterns were assessed from patient diaries. Results： The present study enrolled 160 Korean men （mean age 55 years） with prior median sildenafil use of 585 days. During the extension phase, 73.7% of patients elected to take tadalafil, whereas 26.3% chose sildenafil （P 〈 0.001）. After switching from sildenafil to tadalafil, mean PAIRS time concern scores decreased from 2.54 to 2.42 （P = 0.002）, with no statistically significant differences observed between the sildenafil and tadalafil assessment phases in sexual spontaneity and self-confidence scores. Sexual attempts made 〉 4 h to 〈 36 h post-dose occurred in 4.5% of patients during the sildenafil assessment phase compared with 17.5% during the tadalafil assessment phase. Conclusion： After experiencing both sildenafil and tadalafil, the majority of patients exhibited a preference for tadalafil. This preference might be influenced by psychosocial factors, such as decreased time concerns, and a broader window of opportunity available for sexual activity.

1 前言近年来,紫外固化水基涂料由于可减少空气污染,降低火灾危险,改善现场健康条件,提高安全性,尤其是以水作为紫外固化体系稀释剂,降低了有毒气体对环境的污染,解决了粘度控制和活性稀释剂影响固化膜性能之间的矛盾,而且易于清洗,因而得到广泛的工业应用.有2种水基体系:含外加表面活性剂的乳液或胶体分散液和水溶性或水分散型含亲水性基团的树脂体系.前者制备时通常加入表面活性剂,有助于形成稳定的乳液.但外加的表面活性剂影响最终产品的性能,即留在紫外固化膜中的表面活性剂使涂层具有水敏性.后一种体系不用加入表面活性剂,而是在疏水性分子主链或末端引入亲水性基团,如非离子和离子基团,生成水溶性或水分散型树脂.在引入的亲水基团中,非离子基团的优点是不用有毒的有机中和剂,而离子基团的引入有利于提高固化膜的机械性能.一般认为离子基团形成凝聚体,在基体中形成物理交联,因而提高了最终膜的机械性能.在近期的文章中,我们介绍了用引入亲水性基团的方法合成水分散型和水溶性聚氨酯丙烯酸酯及其紫外固化的性能.本文介绍新型水分散型和水溶性聚氨酯丙烯酸酯的合成及其在紫外固化方面的应用.同时介绍了UV固化涂料性能和新型聚氨酯丙烯酸酯膜的机械性能.

把柠檬酸应用于土壤，可以增强4种农作物植物对铀的堆积。通过添加柠檬酸，印度芥菜枝叶中铀的堆积星较高（平均2000毫克，千克，干重），canola根部中铀的堆积垦较高（3500毫克/千克，干重）。进行试验的植物组织中铀迁移率的关系是：根部〉幼苗≌枝叶。向日葵花卉堆积的铀的浓度接近或高于根部堆积的铀浓度，而向日葵种子中的铀浓度接近于零。总之，由于印度芥菜地上组织较高的铀堆积量，印度芥菜被推荐为是一种可以进行植物提取的物种。向砂质土壤和粘质土壤中添加柠檬酸，两种土壤中的植物对铀的堆积（增强的）没有较大差异（p〈0．05）。然而，结果表明，向土壤中添加柠檬酸可以引起铀向地下迁移，并且能污染地下水。在文章最后也对被植物吸收的铀的物种形成进行了讨论。
