Objective: The primary objective of this study was to evaluate the effect of Paljung-san on lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH). Methods: We researched four men with BPH and LUTS, who were treated 3 times a day for 10 days with Paljung-san. The International Prostate Symptom Score (IPSS) and post void residual urine (PVR) were evaluated. Results: The mean decrease in IPSS total score was 13 points (P=0.007, Mann-Whitney test). The reduction of IPSS was more prominent in the obstructive subscore but was not significant (P=0.057, Mann-Whitney test). Furthermore, Paljung-san reduced PVR. Conclusions: After the 10-day treatment period, Paljung-san improved total IPSS score, especially in the obstructive subscale score, and reduced post void residual urine.

Benign Prostatic Hyperplasia(BPH) is the most common benign tumor seen in the western male, and it is found in 50% of men over 50 years of age. It is characterized by the formation of large discrete lesions in the periurethral region. As they enlarge, these nodules tend to compress the urethra and cause partial or almost complete obstruction of .urine flow. The etiology of BPH is uncertain, but the increasing incidence with advancing age suggests the possibility of an imbalance between male and female sex hormones. In the past, most patients have had multiple indications to support the decision to initiate therapy. But both the urologic surgeon and the patient must be clearly aware of the results that can be expected and the risks involved in achieving them. The aims of this study are to investigate and summarize the current trends of treatment for BPH so as to suggest the effective and available way to treat the disease. In Oriental medicine, the BPH is recognized as uroschesis and ischuria, and the etiology is mainly in stagnated blood and insufficiency of the kidneys. The point of treatment of BPH is recovery of urination, and the treatment can be approached in two ways through herb drugs and acupuncture. Some of the herb drugs have substances which reduce BPB. Acupuncture therapy stimulates the pelvic plexus and is reported to be effective for voiding. Suppository, massotherapy, rectal injection, locus injection and attachment of herb drugs to the navel or the acupoint are announced as the effective treatments. So, this study of the approach and application of these treatments on BPH would be necessary.

Purpose: To evaluate the initial experience and outcome of photo-selective vaporization of the prostate (PVP) for benign prostatic hyperplasia (BPH) in Pakistan with the use of a 980 nm diode laser. Materials and Methods: A prospective study was performed from November 2016 to December 2017. A total of 100 patients diagnosed with bladder outlet obstruction secondary to BPH who planned for PVP were enrolled in the study. PVP was carried out with a diode laser at 980 nm (Biolitec Diode 180W laser) in a continuous wave with a 600 nm (twister) fiber. Baseline characteristics and perioperative data were compared. Postoperative outcomes were evaluated by International Prostate Symptom Score (IPSS), post void residual (PVR) and maximum urinary flow rate (Qmax) at 3 and 6 months after surgery. Results: The mean age was $65.82{\pm}10.42$, mean prostate size was $67.35{\pm}16.42$, operative time was $55.85{\pm}18.01$ and total energy was $198.68{\pm}49.12kJ$. At 3 months and 6 months, significant improvements were noted (p<0.001) in IPSS $7.04{\pm}1.69$ (-18.92), Qmax $19.22{\pm}4.75mL/s$ (+13.09) and and PVR $18.89{\pm}5.39mL$ (-112.80). Most frequent problems were burning micturition (35%) and terminal dysuria (29%). No significant difference in postoperative hemoglobin was seen in patients who were on anti-platelet drugs. Conclusions: PVP with a diode laser is a safe and effective procedure for the treatment of BPH and is also safe in patients who are on anti-platelet agents.

In this study, the marker compounds of Curcumae Rhizoma (CR) were simultaneously quantified by high-performance liquid chromatography equipped with a photodiode array detector and the anti-inflammatory effects of CR extract and marker compounds in human benign prostatic hyperplasia epithelial-1 (BPH-1) cell lines were investigated. The marker components (4S,5S)-(+)-germacrone-4,5-epoxide, furanodienone, and germacrone, were separated on Gemini $C_{18}$ columns ($250mm{\times}4.6mm$, $5{\mu}m$) at $40^{\circ}C$ by using a gradient of two mobile phases eluting at 1.0 mL/min. Prostaglandin $E_2$ ($PGE_2$) levels in Human BPH-1 cells were determined with an ELISA kit. The coefficients of determination in a calibration curve of each analyte were all 0.9997. The limits of detection and quantification of the three compounds were $0.10-0.32{\mu}g/mL$ and $0.30-0.98{\mu}g/mL$, respectively. The content of three compounds, (4S,5S)-(+)-germacrone-4,5-epoxide, furanodienone, and germacrone, in the CR sample were found to be 5.79 - 5.92 mg/g, 4.72 - 4.86 mg/g, and 1.06 - 1.09 mg/g, respectively. Regarding pharmacological activity against benign prostatic hyperplasia, CR and its components significantly suppressed $PGE_2$ levels of BPH-1 cells. The established analysis method will help to improve quality assessment of CR samples and related products. In addition, CR and its components exhibit antiinflammatory activity in BPH-1 cells, suggesting the inhibitory efficacy of these compounds against the pathogenesis of BPH.

BACKGROUND/OBJECTIVES: Benign prostatic hyperplasia (BPH) is the most common prostate disease and one of the most common chronic diseases caused by aging in men. On the other hand, there has been no research on BPH using Abeliophyllum distichum Nakai (A. distichum). Therefore, this study investigated the effects of A. distichum on BPH. MATERIALS/METHODS: A. distichum leaves were extracted with distilled water, 70% ethanol, and 95% hexane as solvents. Subsequently, the inhibitory effects of each A. distichum extract on androgen receptor (AR) signaling were evaluated in vitro. The testosterone-induced BPH model was then used to confirm the efficacy of A. distichum leaves in 70% ethanol extract (ADLE). RESULTS: ADLE had the strongest inhibitory effect on AR signaling. A comparison of the activity of ADLE by harvest time showed that the leaves of A. distichum harvested in autumn had a superior inhibitory effect on AR signaling to those harvested at other times. In the BPH rat model, the administration of ADLE reduced the prostate size and prostate epithelial cell thickness significantly and inhibited AR signaling. Subsequently, the administration of ADLE also reduced the expression of growth factors, thereby inactivating the PI3K/AKT pathway. CONCLUSIONS: An analysis of the efficacy of ADLE to relieve BPH showed that the ethanol extract grown in autumn exhibited the highest inhibitory ability of the androgen-signaling related factors in vitro. ADLE also inhibited the expression of growth factors by inhibiting the expression of the androgen-signaling related factors in vivo. Overall, ADLE is proposed as a functional food that is effective in preventing BPH.

BACKGROUND/OBJECTIVES: Benign prostatic hyperplasia (BPH) characterized by an enlarged prostate gland is common in elderly men. Corni Fructus (CF) and Schisandrae Fructus (SF) are known to have various pharmacological effects, including antioxidant and anti-inflammatory activities. In this study, we evaluated the inhibitory efficacy of CF, SF, and their mixture (MIX) on the development of BPH using an in vivo model of testosterone-induced BPH. MATERIALS/METHODS: Six-week-old male Sprague-Dawley rats were randomly divided into seven groups. To induce BPH, testosterone propionate (TP) was injected to rats except for those in the control group. Finasteride, saw palmetto (SP), CF, SF, and MIX were orally administered along with TP injection. At the end of treatment, histological changes in the prostate and the level of various biomarkers related to BPH were evaluated. RESULTS: Our results showed that BPH induced by TP led to prostate weight and histological changes. Treatment with MIX effectively improved TP-induced BPH by reducing prostate index, lumen area, epithelial thickness, and expression of BPH biomarkers such as 5α-reductase type 2, prostate-specific antigen, androgen receptor, and proliferating cell nuclear antigen compared to treatment with CF or SF alone. Moreover, MIX further reduced levels of elevated serum testosterone, dihydrotestosterone, and prostate-specific antigen in BPH compared to the SP, a positive control. BPH was also improved more by MIX than by CF or SF alone. CONCLUSIONS: Based on the results, MIX is a potential natural therapeutic candidate for BPH by regulating 5α-reductase and AR signaling pathway.

Oxidative stress is a key factor in the pathogenesis of benign prostatic hyperplasia (BPH) that leads to inflammation. This study aimed to evaluate the ameliorative effects of Salvia miltiorrhiza Bunge extract (HLT-101) on BPH through the regulation of oxidative stress and inflammation. A testosterone propionate (TP)-induced BPH rat model was orally administered HLT-101 (20, 40, or 80 mg/kg), and its effects on oxidative stress- and inflammation-related gene expression were examined. Further, HLT-101 was assessed for its effect on reactive oxygen species (ROS) levels and Nrf-2/HO-1 signaling pathways in BPH-1 cells. HLT-101 decreased testosterone-induced excessive free radical production and inflammatory factor activation. Moreover, HLT-101 treatment significantly decreased the intracellular ROS level in the TNF-α and IFN-γ treated BPH-1 cells through the activation of Nrf-2. In addition, HLT-101 treatment inhibited the NF-κB pathway and androgen receptor (AR) signaling, which is highly linked to the pathogenesis of BPH. Therefore, HLT-101 has the potential to be an effective treatment reagent for BPH because of its ability to reduce inflammation and oxidative stress via Nrf-2/HO-1 signaling.

Background : Clinical practice guidelines define "systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances" and help to improve patient care. The purpose of this study is to develop a clinical practice guideline for the most effective diagnoses and treatments of benign prostatic hyperplasia based on patient preference and clinical need. Methods : For this research project, extensive literature searches (208 articles) were conducted. As well, critical reviews and syntheses (meta-analysis) were used to evaluate empirical evidence and significant outcomes of the BPH literature. Questionnaires about clinical practice for BPH patients were distributed and consensus meetings were undertaken to grasp variations in clinical practice and to reach agreement on the guideline's development. The guideline was promoted under the sponsorship of the Korean Medical Association and the Korean urological Cancer. Society. For the task, the Benign Prostatic Hyperplasia Guideline Panel was composed of multidisciplinary experts in the field. Results : BPH is a disease that affects a patient's quality of life. This Clinical Practice Guideline was developed for the typical man over age 50 with symptoms of prostatism, but with no significant medical morbidities such as diabetes or other known causes of voiding dysfunction, such as urethral stricture or neurogenic bladder. The guidelines detail the relative benefits and obstacles associated with all diagnostic and treatment approaches, including watchful waiting. Conclusion : This guideline provides a cornerstone for our medical association. It represents the most current scientific knowledge regarding the development, diagnosis, and treatment of BPH. It will be revised and updated as needed.

본 연구는 전립선비대증이 노화 및 남성호르몬 과다분비로 인해 유발된다는 가설을 바탕으로 순화기간을 마친 12주령이 된 수컷 쥐에 testosterone을 30일간 피하주사하여 노화 및 testosterone 분비 증가로 인한 전립선비대증 유발 모델 rat을 제작하였다. 실험군은 총 4군으로 각 군당 10마리씩 정상군(N 군), 음성대조군(DO 군), 어성초 추출물 투여군(HO 군) 및 양성물질 finasteride 투여군(FO 군)으로 나누어서 진행하였다. 고환절제술을 한 후 testosterone을 투여한 결과 N군에 비해 나머지 세 군, DO, HO 및 FO군 모두에서 체중이 유의적으로 감소하였다. 전립선의 부피는 N군에 비해서 DO군에서 유의적으로 증가하였으며, HO군과 FO군에서는 DO군에 비해 유의적으로 감소되는 경향을 나타내었다. 전립선의 무게 또한 HO군 및 FO군에서 DO군에 비해 유의적으로 감소되었다. 체중 당 전립선의 비율은 N군에 비해 DO군, HO군 및 FO군에서 유의적으로 증가하였으며, 특히 DO군에 비해 HO 및 FO군은 각각 유의적인 감소를 나타내었다. 혈중 testosterone 및 DHT의 농도는 N군에 비해 모든 군에서 유의적으로 증가되었으나, DO군에서 증가된 혈중 testosterone 및 DHT의 농도는 어성초 추출물 및 finasteride의 공급으로 유의적으로 감소되는 경향이었다. 어성초 추출물의 공급으로 인한 조직병리학적 변화양상을 관찰한 결과 어성초추출물 공급군에서는 DO군에 비해 상피세포, acinar gland, 관상피 세포, 세포핵, 분비선들의 변형 및 위축이 감소하여 정상적인 형태를 나타내고, 양성대조군으로 사용된 finasteride 처리군의 형상과 비슷한 양상을 나타내었다. 어성초 추출물에 대한 이러한 효과는 향후 분자생물학적으로 기전연구들이 더욱 필요하지만 본 결과로 미루어 어성초 추출물 내 함유된 다양한 페놀 및 플라보노이드와 같은 생리활성 성분들은 지금까지 알려져 있던 발모 및 여드름 개선뿐만 아니라 이와 유사한 기전을 가지고 있는 전립선비대증 개선에도 효과적으로 기여할 수 있을 것이라 기대된다.
