Purpose: Testosterone replacement therapy is an effective treatment for late-onset hypogonadism (LOH) despite a few con-traindications and side-effects. The aim of this study was to determine whether modified Ojayeonjonghwan (KH-204, Korean herbal formula) improved LOH. KH-204 is a strong antioxidant herbal formula. We evaluated the effect of Korean herbal pre-scription on androgen receptor (AR) expression in an aged rat model of LOH. Materials and Methods: Eighteen-month-old rats were used as aged LOH rat models. Eighteen Sprague-Dawley rats were ran-domly divided into three equal groups of six animals each and treated with one of the following: 1) normal control group (oral administration with distilled water, n=6), 2) KH-204 200 group (oral administration with 200 mg/kg of KH-204, n=6), and 3) KH-204 400 group (oral administration with 400 mg/kg of KH-204, n=6). After four weeks of treatment (once daily, distilled water or KH-204), serum testosterone levels, changes in testicular and epididymal weight, Western blotting analysis of AR ex-pression and measurement of oxidative stress were examined. Results: Treatment with the herbal formulation KH-204 200 mg/kg and 400 mg/kg (1) increased the weights of testis and epi-didymis; (2) increased the level of serum testosterone; (3) increased the level of superoxide dismutase and reduced the level of 8-hydroxy-20-deoxyguanosine; and (4) upregulated AR expression in testicular tissue. Conclusions: KH-204 might be an effective alternative for LOH. It improves antioxidant mechanisms and increases testicular AR expression without side-effects.

<P>To evaluate the adequate therapeutic dosage of clomipramine 15 mg/day and clomipramine 30 mg/day in male patients with premature ejaculation (PE), this study enrolled men aged 20-65 years who met diagnostic criteria for PE including Intravaginal Ejaculation Latency Time (IELT) less than 2 min for at least 75% of their sexual intercourses. Subjects received placebo, clomipramine 15 mg, or clomipramine 30 mg prn (2 similar to 6 h before intercourse) for 4 weeks. Efficacy was assessed using fold change, percentile change, and mean change of IELT, as well as Drug Coitus Interval Time (DCIT). A total of 101 patients were randomized into the placebo group, clomipramine 15 mg group, and clomipramine 30 mg group. Analyses of fold changes of IELT in each group revealed that the IELT of both the clomipramine 15 mg group and clomipramine 30 mg group was significantly increased 4 weeks after administration than the placebo group. Adverse events were reported by 11.76, 32.35, and 57.57% of patients in the placebo group, clomipramine 15 mg group, and clomipramine 30 mg group, respectively. Most common adverse events in the clomipramine treatment groups were gastrointestinal disorders and psychiatric disorders of mild to moderate severity. On-demand regimen of clomipramine 15 mg resulted in a significant improvement in IELT and was superior to a regimen of clomipramine 30 mg in terms of risk-to-benefit ratio.</P>

<P>GreenLight laser photoselective vaporization of the prostate (PVP) was established as a minimally invasive procedure to treat patients with benign prostatic hyperplasia (BPH). However, it may be difficult to achieve adequate tissue removal from a large prostate, particularly those with an enlarged median lobe. The purpose of this study was to investigate the feasibility and clinical effect of a 120-W GreenLight high-performance system laser vaporization-resection for an enlarged prostate median lobe compared with those of only vaporization. A total of 126 patients from January 2010 to January 2014 had an enlarged prostate median lobe and were included in this study. Ninety-six patients underwent vaporization only (VP group), and 30 patients underwent vaporization-resection for an enlarged median lobe (VR group). The clinical outcomes were International Prostate Symptoms Score (IPSS), quality of life (QOL), maximum flow rate (Q max), and post-void residual urine volume (PVR) assessed at 1, 3, 6, and 12 months postoperatively between the two groups. The parameters were not significantly different preoperatively between the two groups, except for PVR. Operative time and laser time were shorter in the VR group than those in the VP group. (74.1 vs. 61.9 min and 46.7 vs. 37.8 min; P?=?0.020 and 0.013, respectively) and used less energy (218.2 vs. 171.8 kJ, P?=?0.025). Improved IPSS values, increased Q max, and a reduced PVR were seen in the two groups. In particular, improved storage IPSS values were higher at 1 and 3 months in the VR group than those in the VP group (P?=?0.030 and 0.022, respectively). No significant complications were detected in either group. Median lobe tissue vaporization-resection was complete, and good voiding results were achieved. Although changes in urinary symptoms were similar between patients who received the two techniques, shorter operating time and lower energy were superior with the vaporization-resection technique. In addition, vaporization-resection may have a beneficial effect on storage symptoms.</P>

Effect of Etomidate and Thiopental on Intraocular Pressure associated with Induction of Anesthesia and Tracheal Intubation (Facilitated with Succinylcholine) Jae Wan Kim, M.D., Yoon Hee Kim, M.D., Sang Woong Lee, M.D. and Sae Jin Choi, M.D. Department of Anesthesiology, College of Medicine, Chungnam National University, Daejeon, Korea Background: Good control of intraocular pressure (IOP) during induction and maintenance of anesthesia is essential for the success of intraocular surgery. Etomidate produces a significant and somewhat greater reduction in IOP than thiopental. This study was designed to compare the effects of etomidate on IOP with those of thiopental in partients receiving succinylcholine, and in whom tracheal intubation was performed. Methods: Forty ASA physical status Ⅰor Ⅱ patients undergoing elective surgery were divided into thiopental group (n = 20) or etomidate group (n = 20). Intraocular pressure was measured before induction, 1,2, and 3 minutes after administration of an intravenous induction agent, after administration of succinylcholne, immediately after intubation and 2 minutes after intubation. Systolic blood pressure and heart rate were recorded simultantaneously. Results: Both agents produced significant decreases in IOP after administration. At 3 minutes after administration of an agent and after administration of succinylcholine, the IOP of the etomidate group was significantly lower than that of the thiopental group (P < 0.05), but there were no significant differences between the groups in IOP at other stages. Conclusions: Etomidate is not a more effective intravenous induction agent to control the increase of intraocular pressure following tracheal intubation with succinylcholine than thiopental (Korean J Anesthesiol 2001; 41: 153~158)

<P><B>Background</B></P><P> Mesenchymal stem cell therapy (MSCT) and defocused low-energy shock wave therapy (ESWT) has been shown to ameliorate erectile dysfunction (ED). However, the interactions and effects of action between MSCT and ESWT remain poorly understood. In this study, we investigated the mechanisms of combination therapy with MSCT and ESWT in a rat model of diabetic ED. </P><P><B>Materials and Methods</B></P><P> Eight-week-old male Sprague-Dawley rats were randomly divided into 2 parts. Diabetic rats induced by streptozotocin (65 mg/kg) were randomly divided into 4 groups: (1) DM control group, (2) DM + ESWT group, (3) DM + MSCT group, and (4) DM + ESWT + MSCT group. The sham group was a normal control group (without streptozotocin). MSCT and (or) ESWT were, respectively, administered to each group according to the proposal for 8 weeks. Immediately after recording of intracavernous pressure (ICP), the penis was then harvested for histologic analysis, ELISA, and Western blotting. </P><P><B>Results</B></P><P> The ratio of ICP/MAP was significantly higher in the DM + ESWT + MSCT group than in ESWT or MSCT treated group (<I>P</I> < 0.05). Also, the treatment stimulated angiogenesis and vasodilatation in the corpus cavernosum (<I>P</I> < 0.05). ESWT increased the quantity of MSCs in the corpus cavernosum and also induced MSCs to express more VEGF in vitro and vivo (<I>P</I> < 0.05) which activated the PI3K/AKT/mTOR and NO/cGMP signaling pathways in the corpus cavernosum. The combination approach stimulated autophagy and decreased apoptosis in the corpus cavernosum. NGF and BDNF expressions were higher in the DM + ESWT + MSCT group than in the DM control group (<I>P</I> < 0.01). Furthermore, the treatment promoted the MSC recruitment by inducing penile tissues to express more PECAM and SDF-1. </P><P><B>Conclusions</B></P><P> Combination of LI-ESWT and MSCT can get a better result than a single treatment by expressing more VEGF which can take part in autophagy by triggering the PI3K/AKT/mTOR signaling pathway. This cooperative therapy would provide a new research direction in ED treatment for the future.</P>

Persistent DO after relief of partial BOO was generated in the rat model, and 6 of the rats with this condition were orally administered WSY-1075. After 4 weeks of administration, cystometry was performed. Additionally, 8-hydroxy-2-deoxyguanosine and superoxide dismutase were measured to evaluate oxidative stress in the bladder. Pro-inflammatory cytokines, such as interleukin-8 and tumor necrosis factor-α, were analyzed, as were the M2 and M3 muscarinic receptors of the bladder.</P><P><B>Results</B></P><P>Significantly increased contraction pressure and a decreased contraction interval were observed in the persistent DO group after relief of BOO. Moreover, oxidative stress, pro-inflammatory cytokines, and M3 muscarinic receptors were significantly increased. After treatment with WSY-1075, significantly reduced DO was observed by cystometry in comparison with the persistent DO group. Additionally, significantly decreased levels of oxidative stress, pro-inflammatory cytokines, and M3 muscarinic receptors in the bladder were observed after treatment with WSY-1075.</P><P><B>Conclusions</B></P><P>Treatment with WSY-1075 improved persistent DO after the relief of BOO mediated by antioxidative and anti-inflammatory effects. Further studies are necessary to identify the exact mechanism of the treatment effect of WSY-1075.</P>

Purpose: This study investigated the effect of goji (Lycium chinense Mill.) on erectile dysfunction in old-aged rats. Materials and Methods: Twenty-four 18-month-old male Sprague-Dawley rats (defined as old-aged rats) were used. Treatment groups contained eight rats each: a control group, goji extract of 150 mg/kg/day group, and goji extract of 300 mg/kg/day group. Treatment was by orogastric tube once daily for 6 weeks. After 6 weeks of treatment, testes weight, serum testosterone, superoxide dismutase, nitric oxide (NO)-cyclic guanosine monophosphate (cGMP)-related parameters, intracavernous pressure/mean arterial pressure, and histological changes were examined. Results: Treatments with goji extracts increased serum testosterone level, increased the expression of endothelial NO synthase, neuronal NO synthase, and cGMP, improved the oxidative stress marker, and decreased corporal fibrosis. Conclusions: Our results indicate that goji extract may have a positive effect on erectile dysfunction via its antioxidant effects.

Purpose: As a minimal invasive device for benign prostatic hyperplasia (BPH) treatment, prostatic urethral lift (PUL) is widely accepted worldwide but not widely used in Korea. We investigated the one-year results of for patients with BPH in Korea.Materials and Methods: From April 2017 to June 2018, 42 patients with BPH were treated with PUL under local anesthesia with sedation. International Prostate Symptom Score (IPSS) and maximum urinary flow rate and post-void residual (PVR) were evaluated preoperatively and 1, 3, 6, and 12 months later.Results: Mean age was 69.57±8.58 years old, and mean prostatic volume was 37.17±12.19 cc. Preoperative total IPSS and quality of life (QOL) were 19.94±7.81 and 3.69±1.30, respectively. Total IPSS improved to 11.26±7.22 (p<0.001), and QOL was 2.42±1.43 (p=0.01) after one month. Patients showed no evidence of inflammation related to the implants. IPSS and QOL were somewhat worse after 3 months but were better than baseline at 6 and 12 months. Preoperative maximum flow rate (Qmax) was 9.71±5.45 ml/sec, and one month after surgery, it had improved to 12.63±7.33 (p=0.01); it remained good at 3, 6, and 12 months (12.63±7.38, 12.45±7.39, 14.73±9.67). PVR was not significant at any points postoperative (80.61±67.91 to 43.95±8.19, p=0.119). No patient reported retrograde ejaculation, erectile dysfunction or urinary tract infection.Conclusions: We evaluated the one-year efficacy of PUL for BPH treatment in Korea, and found significant improvement of IPSS, QOL and Qmax. It is expected that not only the improvement of voiding symptom but also the preservation of sexual function with a low risk of adverse events.
