Benign prostatic hyperplasia (BPH) is the most common prostate disease in middle aged and elderly men. Therefore, identifying risk factors for BPH is crucial for understanding the etiology and for undertaking interventions or targeting strategies. The survey was carried out in two steps: first, pilot study was conducted prior to the main study in order to estimate baseline characteristics. Second, main study investigated prevalence and risk factors of BPH by clinical diagnostic tests and questionnaire. A total of 641 male aged 50-79 years participated in this community-based cross-sectional study. Using 24 hour recall of food consumption, we found that animal fat intakes increased the risk of BPH with adjusted for age, chronic bronchitis, PSA level, drinking frequency, and excercise frequency (odds ratio 1.84,95% confidence interval 1.10-3.06) . Although BPH has been considered as unavoidable disease with advancing age, if these dietary risk factors are clearly identified, it can be prevented effectively by laying special emphasis on those at risk.

Recently, several alternatives have been attempted in the management of benign prostatic hyperplasia (BPH) to reduce morbidity of traditional transurethral resection of the prostate (TURP). Among new modalities, transurethral electrovaporization (TEVP) is considered as a promising alternative. To evaluate the safety and initial efficacy of JEVP using the roller loop electrode (ProSurg Inc. USA) on BPH patients, we compared the results of TEVP with those of TURP and visual laser ablation of the prostate (VLAP). In this study, a total of 115 patients with symptomatic BPH were underwent TEVP (n=17), TURP (n=59) or VLAP (n=39) since 1995. Before treatment, patients were evaluated with an International Prostate Symptom Score (IPSS) and the measurement of maximal uroflow rate (MFR) and postvoid residual urine (PVR). After treatment, the operative and hospital records were reviewed. The uroflowmetry and IPSS were re-evaluated 3-10 months after treatment. In clinical outcome of re-evaluation compared to the preoperative parameters, there was a clinically significant improvement in three procedures. TEVP resulted in 62% reduction in IPSS (TURP, 73% : VLAP, 69%), 84% improvement in MFR (TURP, 113% : VLAP, 91%), and 74% reduction in PVR (TURP, 88% : VLAP, 78%). TEVP had shorter duration of hospitalization and catheterization than the others. TEVP was associated with lower rates of treatment-related complication than TURP. In conclusions, TEVP is considered as a useful procedure to treat symptomatic BPH. And, the advantages of TEVP over TURP include excellent intraoperative hemostasis, lower morbidity, shorter hospital stay and simple technique. In addition the advantages over VLAP include lower cost, shorter duration of catheterization and early symptom improvement.

Agaricus blazei mycelial liquid culture extract (ABMLCE) promoted the production of testosterone (TS) in TM-3 mouse Leydig testis cells. Now, we report that ABMLCE containing eritadenine (EA) as a minor constituent (15.3 mg/100 g) reduced $5{\alpha}-reductase$ 2 ($5{\alpha}-R2$) enzyme activity and dihydrotestosterone (DHT) content which are key constituents for the benign prostatic hyperplasia (BPH) inductions. RWPE-1 prostate cells were grown in a Keratinocyte serum-free medium (K-SFM) containing ABMLCE (0~50 ppm), EA (0~10 ppm,), and finasteride (FS $10{\mu}M$: a positive control) in a 24-well plate for 24 hr. Supernatants collected from cell-cultured media were used for the assay of $5{\alpha}-R2$, superoxide dismutase (SOD), catalase (CAT) and cyclooxygenase-2 (COX-2) enzyme activities, and for TS, DHT, tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) and $interleukin-1{\beta}$ ($IL-1{\beta}$) contents by their assay kits. The $5{\alpha}-R2$ activity and DHT content were proportionally reduced (p<0.05) to concentrations of ABMLCE. The SOD and CAT enzyme activities were significantly (p<0.05) elevated concomitant with ABMLCE concentrations, while COX-2, $TNF-{\alpha}$ and $IL-1{\beta}$ showed reverse results (p<0.05). Similarly, the effects of EA were similar to those of ABMLCE. Efficacies of ABMLCE 50 ppm and EA 10 ppm in $5{\alpha}-R2$ and DHT reduction were similar to those of $10{\mu}M$ FS. These results suggest that ABMLCE and EA reduced $5{\alpha}-R2$ and DHT through their anti-inflammatory and anti-oxidative actions. This implies that ABMLCE containing EA could be a beneficial material in the cure of BPH in humans.

Objectives: The aim of this study is to investigate the effect of Heat-sensitive Moxibustion on Benign Prostatic Hyperplasia Methods: We searched articles from Academic Journals(CAJ) online databases, Oriental Medicine Advanced Searching Integrated System (OASIS), Searching key words were '前列腺增生', '熱敏灸' and '열민구', '전립선비대'. The search range included randomized controlled trials (RCTs). Among the articles published to 2020, 10 articles were found. After review the title, abstract and original, 3 articles were selected finally to rule out treatment combined with completely different treatments. Result: The Heat-sensitive moxibustion at acupoints in the treatment of Benign prostatic hyperplasia were significantly superior to control group after treatment in the symptoms of patients, IPSS, QOL, PVR and Qmax(P<0.05). The Heat-sensitive moxibustion can significantly reduce the incidence of temporary urinary incontinence after Transurethral resection of the prostate(TURP) and improve life quality and satisfaction of patients(P<0.05). The individualized desensitization saturated time and amount of Heat-sensitive moxibustion is superior effective to general amount and time of traditional moxibustion in the total effective rate, IPSS, Ru and Qmax(P<0.01) for Benign prostatic hyperplasia. Conclusion: Heat sensitive moxibustion directly transfer heat to the source of a disease. So it can be considered as a good treatment for Benign prostate hypertrophy. It was also shown a better effect on BPH compared to traditional moxibustion, According to the thermo principles of tumor, if the tumor cell's death temperature of 43℃ is reached, that can cause tumor degeneration. Therefore I think Heat sensitive moxibustion can be applied to various tumor disease. The results of this study could be applied to clinical treatment of BPH. However, additional large-scale clinical researches should be conducted.

Objective : In benign prostatic hyperplasia, dihydrotestosterone acts as a potent cellular androgen and promotes prostate growth. Inhibiting enzyme 5${\alpha}$-reductase, which is involved in the conversion of testosterone to the active form dihydrotestosterone, reduces excessive prostate growth. Recently Scutellaria baicalensis has been related reports about the effect of baicalein on anti-proliferation of the prostate gland. In this study, we investigated the effects of Scutellaria baicalensis on cytopathological alterations and expression of 5${\alpha}$-reductase in the rat model of benign prostatic hyperplasia induced by castration and testosterone treatment. Methods : Sprague-Dawley rat were treated with testosterone after castration for induction of experimental benign prostatic hyperplasia, which is similar to human benign prostatic hyperplasia in histopathological profiles. Scutellaria baicalensis as an experimental specimen, and finasteride as a positive control, were administered orally. The prostates were evaluated by histopathological changes, testosterone levels, and the expression of 5${\alpha}$-reductase genes. Results : While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with Scutellaria baicalensis showed a diminished range of tissue damage. In the reverse transcription-polymerase chain reaction(RT-PCR) of 5${\alpha}$-reductase genes. Scutellaria baicalensis inhibited the expression of 5${\alpha}$-reductase genes. Conclusions : These findings suggest that Scutellaria baicalensis may protect glandular epithelial cells and also inhibit stromal proliferation in association with the suppression of 5${\alpha}$-reductase. From theses results, we suggest that Scutellaria baicalensis could be a useful remedy agent for treating benign prostatic hyperplasia.

Objective : Benign prostatic hyperplasia(BPH) is one of the most common diseased among elderly men. BPH can be treated with alpha-1 adrenergic blocker or $5{\alpha}$-reductase inhibitor(Finasteride) that reduces serum dihydrotestosterone(DHT). Phellodendri Cortex Ex has been broad studied on its chemical components, pharmacological activity, and clinical effects on anti-inflammation, anti-allergy, anti-tumor, immunity, antibacteria and other bioactivities. In this study, we investigated the therapeutic effects and action mechanism of Phellodendri Cortex Ex with a BPH induced by castration and testosterone treatment. Methods : Sprague-Dawley rats were treated with testosterone after castration for induction of experimental benign prostatic hyperplasia, which is similar to human benign prostatic hyperplasia in histopathological profiles. Phellodendri Cortex as an experimental specimen, and Finasteride as a positive control, were administered orally. The prostates were evaluated by histopathological changes, and the expression of $5{\alpha}$-reductase genes. Results : While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with Phellodendri Cortex Ex showed a diminished range of the tissue damage. In the reverse transcription-polymerase chain reaction(RT-PCR) of $5{\alpha}$-reductase genes, Phellodendri Cortex inhibited the expression of $5{\alpha}$-reductase genes. Conclusions : These findings suggest that Phellodendri Cortex Ex may protect the glandular epithelial cells and also inhibit stromal proliferation in association with the suppression of $5{\alpha}$-reductase. From these results, we suggest that Phellodendri Cortex Ex could be a useful agent for treating the benign prostatic hyperplasia.

Objectives : This study aimed to evaluate the randomized controlled clinical trials (RCTs) analyzing the effectiveness of Chuna manual therapy (CMT) for benign prostatic hyperplasia (BPH). Methods : Among the literature published until May 2020, a literature search was carried out using 10 electronic databases using related keywords to identify all RCTs that applied CMT for the treatment of BPH. The Cochrane risk of bias tool was used to assess the methodological quality of each RCT. Results : Five RCTs met our inclusion criteria and were included in the analysis. These studies showed that CMT had no positive results compared to herbal medication. However, positive results were shown in terms of an increased efficacy rate, reduced international prostate symptom scores, and increased maximum flow rate when CMT was combined with acupuncture or herbal medication. Conclusions : Based on the analysis, this review has limited evidence of CMT being beneficial in the treatment of BPH. Therefore, further investigation is required using well-designed RCTs to support the effectiveness of CMT and to obtain higher evidence.
