Benign prostatic hyperplasia (BPH) is one of the common disease in elderly men. Recently old-age population is increased and we are growing more and more interested in clinical importance of BPH. In this study, the effect of PLX, which was the mixture of tomato extract (including 2% of lycopene) and chitooligosaccharide, on prostatic cancer cell and testosterone-induced BPH in adult rats of the Sprague Dawley strain was determined. The cell viability was evaluated by MTT method using L929 and LNCaP cell line, pretreated with various concentrations of PLX. The expression of prostatic specific antigen (PSA) and 5${\alpha$}$-reductase genes were evaluated by realtime PCR using LNCaP cell line and compared various concentrations of PLX with 50 ${\mu}$M of finasteride. An experimental prostatic hyperplasia was induced in male Sprague Dawley rats by giving testosterone for 8 weeks. After 2 weeks from start of giving testosterone, PLX and finasteride were administered orally once a day. The results were analyzed with prostate weight per body weight at 8 weeks. Cell viability of L929 cell line decreased specifically at the concentration of 2000 ${\mu}$g/mf of PLX. The cytotoxicity of PLX to the LNCaP cell line was shown at above 500 ${\mu}$g/ml of PLX. The inhibitory effect of PLX to the expression of PSA and 5${\alpha$}$-reductase genes in LNCaP cell line increased with the concentration of PLX. In vivo study, the results of PLX and finasteride administered group were 3.75${\pm}$0.60 and 3.49${\pm}$0.49 prostate weight ${\times}10^3$/body weight, which were lower than the result of BPH induced group (4.74${\pm}$0.58). These results suggested that PLX may be an effective material in BPH by having the role of the 5a-reductase inhibitor.

Purpose: The aim of this study was to evaluate inflammation parameters and assess the utility of the neutrophil-lymphocyte ratio (NLR) as a simple and readily available predictor for clinical disease activity in patients with nenign prostate hyperplasia BPH. We also aimed to investigate the relationship between inflammatory parameters with ${\alpha}$-blocker therapy response, and evaluate the potential association between NLR and the progression of benign prostatic hyperplasia (BPH). Materials and Methods: We examined 320 consecutive patients (July 2013-December 2013) admitted to our outpatient clinic with symptoms of the lower urinary tract at Bozok University. The mean age was 60 (range, 51-75) years. Complete blood count (CBC), prostate-specific antigen (PSA), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were assessed. Correlations between PSA, CRP, ESR, prostate volume, International Prostate Symptom Score (IPPS), maximum urinary flow rate (Qmax), and NLR were assessed statistically. Patients were divided into two groups: high and low risk of progression. Results: NLR was positively correlated with IPSS (p=0.001, r=0.265), PSA (p=0.001, r=0.194), and negatively correlated with Qmax (p<0.001, r=-0.236). High-risk patients a had a higher NLR compared with low-risk patients, based on IPSS (p<0.001), PSA (p=0.013), and Qmax (p<0.001); however, there were no significant differences between the groups in terms of age (p>0.05), and prostate volume (p>0.05). Conclusions: NLR can predict BPH progression. We propose that increased inflammation is negatively associated with clinical status in BPH patients and suggest that NLR can give information along with LUTS severity which may be used as a readikly accessible marker for patient follow-up.

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.

Benign prostatic hyperplasia (BPH), which is the most common disorder in elderly men, involves androgenic hormone imbalance with chronic inflammation that causes imbalance between cell apoptosis and cell proliferation. As the root cause of the BPH remains unclear and synthetic drugs for treatment of BPH have undesirable side effects, the development of effective alternative medicines has been considered. Chinese Skullcap has been considered natural remedy to treat pyrexia, micturition disorder and inflammation. Although skullcap has effective properties on various diseases, the effects and molecular mechanism of Skullcap on BPH are not fully understood. Therefore, in this study, we evaluated the efficacy of Chinese Skullcap root extract (SRE) in testosterone-induced BPH rats. Compared with the untreated group, the SRE treatment group suppressed pathological alterations, such as prostate growth and increase in serum dihydrotestosterone and $5{\alpha}$-reductase levels. Furthermore, SRE significantly decreased the expression of androgen receptor and proliferating cell nuclear antigen. SRE also restored Bax/Bcl-2 balance. These effect of SRE was more prevalent than commercial $5{\alpha}$-reductase inhibitor, finasteride. Taken together, we propose that SRE suppresses abnormal androgen events in prostate tissue and inhibits the development of BPH by targeting inflammation- and apoptosis-related markers. These finding strengthens that SRE could be used as plant-based $5{\alpha}$-reductase inhibitory alternative.

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.

Morphometry of nuclei of the benign and malignant prostatic lesions was performed to study the relationship between nuclear size and shape and the prognosis of prostatic adenocarcinoma fifty one cases of prostatic adenocarcinoma and 13 cases of benign prostatic hyperplasia were included to evaluate area, perimeter, Dmax, Dmin, and 5 form factors of the nuclei by image analyzer(Zeiss Ibas 2000) using hematoxylin-eosin stained slides. All analytic factors of nuclear size and shape were significantly different between benign lesions and adenocarcinomas. Increased nuclear size was associated with nuclear irregularity, presence of metastasis, advanced clinical stage, and high Gleason's grade and score of prostatic adenocarcinoma. On Kaplan-Meier method, survival was decreased with older age, no hormonal treatment, stage D, high Gleason's grade and stage as well as with larger size and irregular shape of the nuclei in conclusion, morphometry of nuclei of the prostate can be a helpful tool to differentiate between be nign and malignant lesions. Nuclear morphology is thought to be associated with prognosis of prostatic adenocarcinoma.

Trichomoniasis is the most common curable sexually-transmitted infection. Most Trichomonas vaginalis-infected men are asymptomatic and can remain undiagnosed and untreated, and this has been thought to result in chronic persistent prostatic infection. Chronic inflammation is regarded as the major factor in the pathogenesis and progression of benign prostatic hyperplasia (BPH) and prostatic cancer (PCa). The aim of this study is to identify seropositivity to T. vaginalis in men with prostate tumors (BPH or PCa) visited to Hanyang University Hospital. A total of 183 men were enrolled between October 2013 and November 2014. They consisted of 139 with BPH (mean age: $64.0{\pm}0.07$) and 44 with prostate cancer (mean age: $73.3{\pm}0.18$). We carried out ELISA to identify the seropositivity to T. vaginalis. Mixed lysate antigen extracted from 8 strains of T. vaginalis was used in the ELISA. Also 58 male outpatients visited to Health Promotion Center in Hanyang University Hospital were evaluated for comparing group. As a results, seropositivity to T. vaginalis in patients with prostatic diseases was 19.7% (BPH: 18.7%, PCa: 22.7%) and it was significantly higher than the 1.7% of the comparing healthy group (P=0.001). Therefore, prostatic tumor showed higher seropositivity against T. vaginalis than normal men. As far as we know, this is the first report about seroprevalence in prostatic tumor in Korea.

Benign prostatic hyperplasia (BPH), which is commonly found in aging men, is characterized by hyperplasia of prostatic stromal and epithelial cells beginning in the periurethral zone of the prostate. The prevalence of BPH increases in an age-dependent manner. Here, we investigated the protective effects of unripe Rubus occidentalis extracts (UROE) on BPH development using a prostate cancer cell line and testosterone-induced BPH rat model. Experiments using an established hormone-dependent prostate cancer cell line (LNCaP) showed that UROE treatment significantly decreased expression of androgen-related genes, including androgen receptor (AR), prostate specific antigen (PSA), and 5-alpha reductase 2, but not 5-alpha reductase 1, which was also observed in flutamide-treated cells. Further, AR and PSA gene expression was reduced by UROE treatment under androgen-stimulated conditions using dihydrotestosterone (DHT). BPH animals displayed elevated prostate weights. However, UROE as well as finasteride treatment significantly reduced prostate weights and DHT levels compared to testosterone-induced BPH animals. Histopathological analysis also showed that UROE treatment suppressed testosterone-induced prostatic hyperplasia. Taken together, the results suggest that UROE may effectively inhibit the development of BPH and thus may be a useful agent in BPH treatment.

Objectives : Benign prostatic hyperplasia (BPH) is one of the most common diseases among elderly men. Though medicines such as 5${\alpha}$-reductase inhibitor (finasteride) have recently been developed for treating BPH, their adverse effects and low efficacy should not be overlooked. Curcuma longa has a long history of use in traditional medicines of Asian countries. Many reports conclude the component curcumin in Curcuma lonfa, has the potential to treat various diseases including prostate cancer. In this study, we investigated the therapeutic effects and action mechanism of Curcuma longa with a BPH rat model. Methods : Sprague-Dawley rats were used with subcutaneous injection of testosterone after castration, which were histologically similar to human BPH. A total of 30 rats were equally divided into five groups: Group 1 served as control (sham-operated group): Group 2 was the model group: Group 3 and Group 4 animals were administered Curcuma longa at dose levels of 0.5g/kg and 1.0g/kg: Group 5 served as a positive control group and was treated with finasteride at a dose of 1 mg/kg. The drugs were administered orally once a day for 30 days consecutively. After 31 days, the prostates were removed, and analyzed for their prostatic weight and histological examination. Results : The oral Curcuma longa ingestion group showed statistically significant decreases in their prostatic weights compared with the BPH-induced group and the oral finasteride ingestion group (p<0.05). Curcuma longa is also very safe in liver and kidney up to a dose of lg/kg. Injected testosterone histologically led to prostatic hyperplasia in rats, but oral Curcuma longa ingestion decreased this change. Conclusions : These results suggest that Curcuma longa has a definite inhibitory effect on BPH and might be an alternative medicine for treatment and prevention of human BPH.
