Benign prostatic hyperplasia (BPH) is one of the most common diseases among elderly men. As the old-age population is increasing recently, it is to our interest to observe the growing BPH within them. In BPH, the dihydrotestosterone (DHT) acts as promotes prostate growth. It inhibits enzyme $5{\alpha}$-reductase that is involved in the conversion of testosterone to the DHT activity which reduces the excessive prostate growth. Through experiments, the effects of Phellius linteus water extract performed on the BPH rats were induced by testosterone treatments. For 12 weeks, Sprague-Dawley rats were treated with testosterone for the induction of BPH. Rats were divided into four experimental groups: the not treated group (N), the testosterone injection and D.W treatment group (TN), the testosterone injection and Phellinus linteus treatment group (TP) and testosterone injection and finasteride treatment group (TF). Prostate weight, volume and weight ratio in the TP group and the TF group were significantly lower than the TN group. Testosterone and DHT levels in the TN group were significantly higher than that of the N group. And the TP group was significantly decreased than that of the TN group. While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation; the TP and TF groups showed trophic symptoms and were lined by flattened epithelial cells, thus, the stromal proliferation is relatively low as compared to the TN group. These suggest that Phellinus linteus water extracts may be an useful remedy for treating the benign prostatic hyperplasia.

This study is to increase the accuracy of the diagnosis of benign prostatic hyperplasia by presenting a method that can accurately measure the residual urine amount of the bladder by using an ultrasound image. Agar powder, Propanol and distilled water were used as materials for making a phantom. In order to measure the volume, a $10m{\ell}$ cylinder, syringe and beaker were used. The image was obtained by scanning phantoms produced into six shapes. Each constant value was obtained by using the expression designed to measure the residual urine amount of the bladder and was compared and analyzed. The measuring method of Bladder volume was presented and a constant value for each shape was obtained and five observers measured it five times. According to the results of clinical application, the errors of Ellipse-beanbag, Shield-shield were 11.0%, 18.2%, respectively. Constant values depending on the shape of each phantom were presented in order to accurately measure the volume of the bladder in measuring the amount of residual urine for the diagnosis of benign prostatic hyperplasia. The accuracy of the volume using this was verified statistically(p > 0.05). Therefore, it is considered to be useful in diagnosing benign prostatic hyperplasia by using the ultrasound imaging measuring method presented.

In the present study, we investigated the inhibitory effect of heat-killed Enterococcus faecalis (E. faecalis) and live E. faecalis on benign prostatic hyperplasia (BPH). The BPH rat model was established by administering male rats with testosterone propionate (TP, 5 mg/kg, in corn oil) via subcutaneous injections daily for four weeks after castration. The rats were divided into five groups: Con, corn oil-injected (s.c.) + DW administration; BPH, TP (5 mg/kg, s.c.) + DW administration; BPH+K_EF, TP (5 mg/kg, s.c.) + heat-killed E. faecalis (7.5 × 10¹² CFU/g, 2.21 mg/kg) administration; BPH+L_EF, TP (5 mg/kg, s.c.) + live E. faecalis (1 × 10¹¹ CFU/g, 166 mg/kg) administration; BPH+Fi, TP (5 mg/kg, s.c.) + finasteride (1 mg/kg) administration. In both of BPH+K_EF and BPH+L_EF groups, the prostate weight decreased and histological changes due to TP treatment recovered to the level of the Con group. Both of these groups also showed regulation of androgen-signaling factors, growth factors, and apoptosis-related factors in prostate tissue. E. faecalis exhibited an inhibitory effect on benign prostatic hyperplasia, and even heat-killed E. faecalis showed similar efficacy on the live cells in the BPH rat model. As the first investigation into the effect of heat-killed and live E. faecalis on BPH, our study suggests that heat-killed E. faecalis might be a food additive candidate for use in various foods, regardless of heat processing.

Objectives : The aim of this study is to evaluate the effect of Paljeong-san pharmac-opuncture(PJS) on the rat model of benign prostatic hyperplasia(BPH). Methods : Rats were divided into 5 groups, with 6 rats in each group. The 5 groups included sham-operated group(sham group), BPH model group(BPH group), finasteride-treated group (fina group), PJS-treated groups(PJS 10 and PJS 100 group). Testosterone was injected subcutaneously to the castrated rats except sham group for BPH model. During 4-week experimental period, finasteride(5 mg/kg) was administrated orally once daily in fina group, PJS in PJS 10(10 mg/kg) and PJS 100(100 mg/kg) group and normal saline in sham and BPH group were injected subcutaneously once daily at Jungwan($CV_{12}$). We checked prostate weights, serum concentration of dihydrotestosterone(DHT), morphologic changes of the prostate, and the amount of expression of the proliferating cell nuclear antigen(PCNA) and $5{\alpha}$-reductase gene to evaluate the effect of PJS after 4-week experimental period. Results : 1. PJS and finasteride treatment reduced prostate weights comparing with BPH group, but PJS-treated groups showed no significant changes, unlikely fina group. 2. PJS-treated groups showed significant degreases in concentration of DHT. 3. PJS-treated groups showed significant degreases concentration-dependently in the amount of expression of the PCNA and $5{\alpha}$-reductase gene. 4. PJS treatment showed shrinking of thickness in the prostatic epithelial tissue. Conclusions : PJS has the effects that improve the symptoms of BPH through inhibiting proliferation of the prostatic tissues.

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.

Background: Prostatic adenocarcinoma by Prosate cancer (PCa) is the most prevalent cancer and the second cause of cancer-related death among men in the Western world. Human papilloma virus (HPV) may be considered as a preventable risk factor. In this study, we assessed the frequencies of HPV infection in prostatic adenocarcinoma and benign prostatic hyperplasia (BPH) cases in Northeast Mexico. Materials and Methods: A total of 87 paraffin-embedded blocks (from 25 and 62 patients with definite diagnoses of BPH and adenocarcinoma, respectively) were selected and subjected to INNOLiPA HPV Genotyping to detect 28 high- and low-risk HPV types. The rates of infection were compared in the two studied groups. Results: INNOLiPA HPV demonstrated great sensitivity for HPV detection on paraffin-embedded tissue. Global prevalence was 14.9% (13/87). HPV infection was positive in 19.4% (12/62) of patients with adenocarcinoma and 4.0% (1/25) of patients with BPH. HPV-11, which is considered to be low risk, was more prevalent. Interestingly, one patient with BPH and six with prostate cancer showed examples considered to be high risk (HPV-18, -51, -52, and -66). Conclusion: A higher rate of HPV infection among Mexican patients with prostatic carcinoma than among those with BPH was observed. HPV infections may thus contribute to the risk of prostate cancer. Further studies are required to elucidate any roles of HPV infection in prostate disease in Mexico and the effect of prevention and treatment of HPV infection on prostatic adenocarcinoma.

Purpose: This study was done to examine the relationship of low urinary tract symptoms (LUTS), depression, sexual function, and health-related quality of life (HRQoL), and to identify factors influencing HRQoL in patients with benign prostatic hyperplasia (BPH) living in the community. Methods: A total of 218 patients with BPH were recruited into the study. The data were collected by personal interviews using questionnaires and were analyzed with SPSS (version 17.0) computer program, and included descriptive statistics, one-way ANOVA, Pearson's correlation coefficient, and stepwise multiple regression analysis. Results: The relationship between HRQoL and LUTS with depression had a significant negative correlation, whereas the relationship between HRQoL and sexual function had a significant positive correlation. Depression, age, LUTS, number of chronic disease, and excercise were found to be significant predictors (35.6%) of the Physical Component Summary of HRQoL. Depression, stress, smoking, LUTS, and sexual function were found to be significant predictors (48.2%) of the Mental Component Summary of HRQoL. Conclusion: To improve HRQoL of patients with BPH, nurses should focus on the factors identified in this study when doing nursing assessments, and should develop nursing intervention programs for BPH prevention and symptoms management in primary care settings.

In recent years, the number of patients with benign prostatic hyperplasia (BPH), a condition that commonly occurs in elderly men, has increased due to aging and the adoption of western dietary habits. Treatment with chemical drugs, such as finasteride or dutasteride, can cause side effects such as erectile dysfunction or sexual problems. This necessitates the development of remedies using natural substances derived from food ingredients. In this study, we investigated the inhibitory effects of Oxya chinensis sinuosa hot water extract (OCH) on BPH production in LNCaP cells, a hormone-dependent prostate cancer cell line. We found that the mRNA expression of androgen receptor (AR), prostate specific antigen (PSA), and, 5α-reductases 1, and 2 decreased following treatment with OCH. Furthermore, OCH treatment resulted in reduced protein expression of BPH regulators, such as AR. Collectively, these results suggest that OCH exerts a beneficial effect on BPH by inhibiting the AR signaling pathway, indicating the potential of OCH as a therapeutic agent for the prevention and treatment of BPH.

Purpose: The purpose of this study is to evaluate effects of aroma foot bath on urination status (Prostatic Symptom and bother score due to urinary symptoms) and stress related to urination in patients with benign prostatic hyperplasia (BPH). Methods: This study consists of pre- and post-tests in a non-equivalent group design. The 52 BPH patients selected by random sampling in G City were assigned to two groups (experimental group=26, control group=26). Data of their general characteristics, urination status and stress related to urination were collected using self-reported questionnaires. Aroma Foot Bath was performed to the experimental group for 15-20 minutes every day for a week. Descriptive statistics and independent t-test were used for the analyses in this study with the SPSS/WIN 21.0 version program. Results: Prostatic symptom and bother score due to urinary symptoms in the experimental group were improved than those in the control group (t=-7.94, p<.001). Compared to the control group, the stress related to urination in the experimental group (t=-8.78, p<.001) was significantly reduced (t=-5.21, p<.001). Conclusion: The results of this study indicate that aroma foot bath is effective in improving urination status and reducing stress related to urination in BPH patients.

Background: The role of inflammation in prostate diseases is suggested by the presence of inflammatory cells within the prostate in benign prostatic hyperplasia (BPH) and prostate cancer (PCa) patients. In addition, bacterial and viral infection may lead to chronic and recurrent inflammation of the prostate. The human papillomaviruses (HPVs) are a family of sexually transmitted viruses which have been implicated in the aetiology of cervical cancer and several other malignancies. This study evaluated the frequency of HPV infection in individuals with prostatic disease in Iran. Materials and Methods: The study included formalin fixed paraffin- embedded tissue samples of 196 primary prostate cases, including 29 PCa and 167 BPH samples. HPV DNA was purified and amplified through MY09/MY11 and GP5+/GP6+ primers with nested PCR. All patients were interviewed using a questionnaire to collect demographic information. Results: Nested PCR showed that HPV DNA was found in 17.2 percent of PCa samples and 4.8 percent of BPH samples (not significant). Conclusions: Our data do not support a significant role of HPV infection in prostatic disease in Iranian patients, but demographic data indicated a probable association between presence of HPV DNA and risk of inflammation in prostate tissue which might lead to prostate carcinoma. Further studies are required to elucidate any roles of HPV infection in prostatic disease.
