The purpose of this study was to identify factors influencing sleep disturbance among benign prostate hyperplasia (BPH) patients in South Korea. A trained reporter filled out the questionnaire by explaining and reading the sentences to 164 BPH patients in J city. The questionnaire consisted of international prostate symptom score (IPSS), anxiety, depression, sleep disturbance. There was a statistically significant difference in sleep disturbance of participants according to income, regular exercise, and number of disease. There were statistically significant correlations between sleep disturbance and IPSS (r=.45, p<.001), anxiety (r=.59, p<.001), depression (r=.42, p<.001). The influential factors for sleep disturbance were anxiety (${\beta}=.41$, p<.001), income (${\beta}=-.36$, p<.001), IPSS (${\beta}=.28$, p=.021). These factors accounted for 41.2% of the variance in sleep disturbance. The result of this study can be used as a basic data for development of a management strategy considering convergent relationship between IPSS and anxiety in order to decrease sleep disturbance of BPH patients.

Purpose: This study was done to examine the relationship of benign prostatic hyperplasia(BPH) symptoms, anxiety, and depression, and to identify factors influencing quality of sleep in patients with BPH. Methods: 86 BPH patients were the subjects of this study. The collected data was analyzed into descriptive statistics, t-test, ANOVA, Pearson's correlation, and multiple regression analysis. Results: The quality of sleep of the BPH patients had negative correlations with BPH symptoms, anxiety, and depression. The significant factors influencing quality of sleep were house income, anxiety, explained 43.2% of the variance. Conclusion: It is necessary to develop a nursing intervention that manages anxiety decrease of the BPH patients.

Prostate ultrasound is used to diagnose prostate cancer, BPH, prostatitis and biopsy of prostate cancer to determine the size of prostate. BPH is one of the common disease in elderly men. Prostate is divided into 4 blocks, peripheral zone, central zone, transition zone, anterior fibromuscular stroma. BPH is histologically transition zone urethra accompanying excessive nodular hyperplasia causes a lower urinary tract symptoms(LUTS) caused by urethral closure as causing the hyperplastic nodule characterized finding progressive ambient. Therefore, in this study normal transition zone image for hyperplasia prostate and normal transition zone image is analyzed quantitatively using a computer algorithm. We applied texture features of GLCM to set normal tissue 60 cases and BPH tissue 60cases setting analysis area $50{\times}50pixels$ which was analyzed by comparing the six parameters for each partial image. Consequently, Disease recognition detection efficiency of Autocorrelation, Cluster prominence, entropy, Sum average, parameter were high as 92~98%.This could be confirmed by quantitative image analysis to nodular hyperplasia change transition zone of the prostate. This is expected secondary means to diagnose BPH and the data base will be considered in various prostate examination.

We evaluated the benign prostatic hyperplasia (BPH) with Yacon pill, the preparation composed of Smallanthus sonchifolius, Torilis japonica and Acorus gramineus. A total of 45 rats were divided into five groups. One group was used as a control and the other groups received subcutaneous injections of testosterone for 4 weeks to induce BPH. Yacon pill extract (200 or 400 mg/kg) was administered daily for 4 weeks to two groups by oral gavage concurrently with testosterone. The rats euthanized, the prostate and body weights were recorded, and tissues were subjected to hormone assay. In addition, we investigated proliferating cell nuclear antigen (PCNA) expression in the prostate using immunoblotting. Rats with BPH showed significantly increased prostate weights, increased dihydrotestosterone (DHT) levels in the serum and increased PCNA expression in the prostate; however, Yacon pill extracts treated rats showed significant reduction of prostate weights, DHT levels and PCNA expression compared with the BPH group. Conclusively, Yacon pill showed the possibility as ameliorable agents of BPH symptoms.

We reported previously that the extracts of Yacon tuber and leaf have spermatogenic activity and testosterone level increasing effect in men. The aim of this study was to investigate the mechanism of testosterone level increasing effect of Yacon tuber and leaf extracts. In this study, we found that Yacon leaf extracts and chlorogenic acid, a constituent of Yacon extracts showed significantly inhibition effect of testosterone degradation in rat liver homogenate. We suggest that this could be a part of direct mechanism about increasing effect of testosterone level. Futhermore, we evaluated the inhibition effect of testosterone metabolism of Torilis japonica and Coix lacryma-jobi have been reported as $5{\alpha}$-reductase inhibitor. The inhibition ratio of testosterone metabolism of these were Torilis japonica>Coix lacryma-jobi>Yacon. We also evaluated the benign prostatic hyperplasia (BPH) score with the preparation composed of these natural product, Yacon pill. It showed the decreased the BPH score in men. Rats with BPH showed significantly increased dihydrotestosterone (DHT) levels in the serum; however, Yacon pill extracts treated rats showed significant reduction of DHT levels compared with the BPH group. Conclusively, Yacon pill showed the possibility as ameliorable agents of BPH symptoms.
