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： sham- operated （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 pdor 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.

Improvement of erectile function by Korean red ginseng （Panax ginseng） in a male rat model of metabolic syndrome

引用

Asian Journal of Andrology 2013年第3期15卷 395-399页

作者： Sung-Dae kim Young-Joo kim Jung-Sik Huh sae-woong kim Dong-Wan Sohn Department of Urology School of Medicine Jeju National University Jeju 690767 Korea Department of Urology College of Medicine The Catholic University of Korea Seoul 150713 Korea

The seriousness of metabolic syndrome is not due to the disease itself but its promotion of other diseases, such as erectile dysfunction and cardiovascular and cerebrovascular diseases. We investigated the effects of Korean red ginseng （KRG, Panax ginseng） extract on erectile function in a rat model of metabolic syndrome. We divided the rats into three groups： control, metabolic syndrome＋normal saline （N/S） and metabolic syndrome ＋ KRG. To determine the occurrence of metabolic syndrome in all groups, body weight and various biochemical parameters （e.g., blood glucose, insulin, cholesterol） were measured, and the intra-abdominal glucose tolerance test was performed. To investigate penile erection, the peak intracavernosal pressure （ICP）, mean arterial pressure （MAP） and Masson＇s trichrome stain were evaluated. Erectile function was also investigated by measuring the cyclic guanosine monophosphate （cGMP） levels of the corpus cavernosum. We found that the various biochemical parameters and body weight were similar in the metabolic syndrome＋KRG group and the control group, although the values were slightly higher. The peak ICP/MAP ratio of the metabolic syndrome＋N/S group was markedly decreased compared to the other groups. The cGMP level of the corpus cavernosum in the metabolic syndrome＋N/S group was significantly lower than that of the other groups. As demonstrated in this model of metabolic syndrome with erectile dysfunction, KRG may improve erectile function.

We evaluated the biocompatibility of a dimethylpolysiloxane-coated micro-device which had been designed for monitoring real-time bladder volume in previous studies. The extract assay with dimethylpolysiloxane which had been used for coating the micro-device to measure the bladder volume was performed as an in vitro cytotoxicity test. For in vivo biocompatibility testing, the inflammatory responses around the implantation site of the micro-device in subcutaneous tissue of rat were assessed by light microscope with H＆E stain and fluorescence microscope with ED1 stain and von Willebrand factor stain. The averages of cell viability in dimethylpolysiloxane group were 84.6% and 82.3% at 24 h and 72 h incubation, respectively. The qualitative evaluations with light and fluorescence microscope revealed that the inflammatory changes peaked during 2 weeks but almost disappeared at 4 weeks after implantation of devices. The quantitative evaluations for granulation layer formation and neovascularization showed that the thickness of the layer in dimethylpolysiloxane group peaked during 2 weeks but it came to be stabilized at 4 weeks as thin as at 2 weeks in control group, and the frequency of neovascularization was higher in dimethylpolysiloxane group than in control group but it was not increased with time. The dimethylpolysiloxane-coated micro-device is thought be a reliable bio-medical device.

Aim： To evaluate the efficacy and safety of SK3530, a newly developed type 5 phosphodiesterase inhibitor （PDE5I）, in Korean men with erectile dysfunction （ED）. Methods： A total of 119 patients were randomized at 10 centers in Korea to receive either SK3530 （50, 100, or 150 mg; n = 89） or placebo （n = 30） taken 1 h before anticipated sexual activity for an 8-week period. The patients were evaluated at baseline and 4 and 8 weeks after beginning therapy. Efficacy was assessed using the International Index of Erectile Function （IIEF）, Sexual Encounter Profile （SEP）, and the Global Assessment Question （GAQ）. Safety was analyzed by adverse events, laboratory values and vital signs. Results： At the end of the study, all the primary and secondary efficacy end-points were statistically significantly improved by SK3530 compared with placebo （P 〈 0.05）. Of the 89 patients in the treatment arm, 36 （42.3 %） achieved normal erectile function after treatment, including six patients with severe ED. Treatment-related adverse events occurred in 32 patients. The most common adverse events were flushing, headache, dizziness and eye redness （10.9%, 7.6%, 2.5% and 2.5%, respectively）, and most were mild. Only two patients discontinued treatment during the study period because of adverse events. Conclusion： The results of our phase Ⅱ study have confirmed the efficacy and safety of SK3530 in a broad population of men with ED of various etiologies and severity. The optimal doses in terms of efficacy and safety were determined to be 50 mg and 100 mg, respectively.

This study was undertaken to determine the impact on ejaculatory function of tamsulosin （0.2 mg） given once daily （OD） for 12 weeks and to identify risk factors for ejaculatory dysfunction in patients undergoing this treatment. Males with an International Prostatic Symptom Score （IPSS） ≥ 8 were enrolled in this study. All participants completed questionnaires, including the IPSS and the Male Sexual Health Questionnaire （MSHQ）, and serum prostate-specific antigen, transrectal ultrasound and uroflowmetry with post-void residual were measured. After initiating 0.2 mg OD tamsulosin, patients were re-evaluated on the fourth and twelfth weeks of medication. The chi-squared test, the independent t-test and one-way ANOVA were used to compare means. Binary logistic regression analysis was used to calculate the odds ratio for all risk factors. A total of 177 men constituted the study cohort. No significant difference was observed between baseline and follow-up for the erectile function, ejaculatory function, satisfaction, sexual activity and desire domains （EFD, EjFD, SDA and ADD） or for erectile or ejaculatory bother mean scores. After 12 weeks, the overall incidence of ejaculatory dysfunction （EjD） was 13.4%. Incidences of the seven different types of EjD （decreased frequency, delay, dryness, decreased strength/force, decreased volume, decreased pleasure and pain at ejaculation） were 2.4%, 3.1%, 3.9%, 3.9%, 6.3%, 7.1% and 3.1%, respectively. Baseline EjFD scores were higher for I PSS responders than for non-responders （26.09 vs. 24.06, P=0.03）. An EjFD score reduction was more frequent in IPSS responders. The incidence of EjD was small, but not negligible and was more frequent in patients with less lower urinary tract symptoms, a smaller prostate, higher baseline MSHQ totals and higher EjFD scores.

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.

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.
