Benign prostatic hyperplasia (BPH) is frequently observed in intact middle-aged or older male dogs with symptoms ranging from asymptomatic to various symptoms such as urination, dyschezia, dysuria, tenesmus, and intermittent serosanguinous or clear serous exudate. A 4-year-old, intact male Welsh corgi with symptoms of intermittent hematuria and serosanguinous exudate at the urethral opening was diagnosed with BPH and intraprostatic hematocyst through ultrasonographic examination and cytology test. The dog was internationally adopted for reproductive purposes and needed to undergo BPH treatment while maintaining fertility. Thus, 2.5 mg finasteride was administered orally once a day for treatment option and therapeutic effects were observed, including loss of clinical symptoms and reduced prostate and intraparenchymal cyst size.

Background. This study was done to identify the prevalence of benign prostatic hyperplasia(BPH) and BPH-related symptoms among community-dwelling elderly men in Korea. In addition, quality of life and health care-seeking behavior were explored. Methods. A total of 417 elderly men were surveyed using the IPSS (International Prostatic Symptom Score) and a structured questionnaire on health care-seeking behaviors. Results. The prevalence of BPH was $19.7\%$. Of those with BPH, $80.3\%$ reported mild symptoms, $13.2\%$ moderate symptoms, and $6.5\%$ severe symptoms. The severity of BPH-related symptoms was significantly correlated with quality of life. Among those with BPH, $42.7\%$ had never consulted with anyone about their symptoms. Conclusions. BPH has emerged as a serious public health problem in elderly men. Elderly people who experience worse symptoms of BPH have a lower quality of life. Many elderly with BPH do not seek health care, mainly due to misconceptions about BPH. The provision of educational programs for BPH may significantly improve the quality of life of elderly men.

This study aimed to investigate variables affecting subjective memory impairment in the elderly with benign prostatic hyperplasia. We used 179 survey data collected from the urology department of two metropolitan general hospitals. The subjects were patients with benign prostatic hyperplasia. T-test, one-way analysis of variance, and $Scheff{\acute{e}}^{\prime}s$ test were performed to identify differences among variables. Pearson's correlation-coefficient and stepwise multiple regression were used to identify variables that affect subjective memory impairment. This study revealed that lower urinary tract symptom and activities of daily living were statistically significant variables, with an explanatory power of 30.0%. The lower urinary tract symptom was due to the benign prostatic hyperplasia increasing the risk of subjective memory impairment. Treatment of the lower urinary tract symptom was delayed because as the elderly got older, they increasingly recognized benign prostatic hyperplasia as a reasonable symptom. Timely intervention and early screening are necessary to prevent lower urinary tract symptom. Finally, programs to reduce the incidence of lower urinary tract symptom and educate nurses to assess, evaluate, perform intervention for subjective memory impairment should be developed.

Objectives: To evaluate the reliability of a pattern identification tool for benign prostatic hyperplasia and to examine the relationship between pattern identification tool readings and IPSS and uroflowmetry. Methods: We analyzed 56 patients diagnosed with benign prostatic hyperplasia from December 27th, 2017 to December 26th, 2018 by two different Korean medical doctors and followed with a pattern identification tool and by IPSS and uroflowmetry. One week later, the patients were retested to analyze the reliability of the pattern identification tool, determined with the intraclass correlation coefficient (ICC) using the test-retest method. The correlation between IPSS and uroflowmetry was analyzed with the Pearson coefficient. Result: The reliability of the pattern identification tool for benign prostatic hyperplasia was evaluated as "poor agreement beyond chance" (ICC=0.349). The reliability of each pattern identification score was evaluated as "good" for Yang Deficiency of Kidney, Yin Deficiency of Kidney, Deficiency of Middle Qi, and Dampness-heat of Lower Energizer. The internal consistency was evaluated as "good" for Yang Deficiency of Kidney, Yin Deficiency of Kidney, and Dampness-heat of Lower Energizer, and as "excellent" for Deficiency of Middle Qi. The correlation between pattern identification and IPSS was evaluated as a "moderate positive correlation" for all pattern identifications. The average flow rate and maximum flow rate using uroflowmetry was evaluated with "moderate negative correlation" for Yang Deficiency of Kidney and Dampness-heat of Lower Energizer. Conclusion: The reliability of a pattern identification tool for benign prostatic hyperplasia was evaluated as "poor agreement beyond chance." Further research is needed.

Objective: This study evaluates the effectiveness and safety of moxibustion for benign prostatic hyperplasia (BPH). Methods: Using the keywords "benign prostatic hyperplasia", "benign prostatic hypertrophy", "benign prostatic enlargement", "prostatic hyperplasia", and "moxibustion", we searched papers in numerous databases, including National Discovery for Science Leaders (NDSL), Korean Traditional Knowledge Portal (KTKP), Oriental Medicine Advanced Searching Integrated System (OASIS), Research Information Sharing Service (RISS), PubMed, Embase, and CENTRAL. The search range included randomized controlled trials (RCTs). Papers not matched with inclusion criteria were excluded. The methodological quality of each RCT was assessed using the Cochrane risk-of-bias tool. Where appropriate, meta-analyses were performed. Results: Initially, 77 studies were found. Of these, 11 duplicate studies were removed and 27 were excluded following title and abstract screening. After the remaining 39 papers were scanned, 13 RCTs were selected and analyzed. Among these 13 RCTs, five compared moxibustion therapy and oral medication, seven compared moxibustion plus acupuncture therapy and oral medication, and one compared moxibustion plus acupuncture therapy and sham-moxibustion. The meta-analysis showed positive results for the use of moxibustion therapy in terms of International Prostate Symptom Score (IPSS), Quality Of Life (QOL), Maximum Flow Rate (Qmax), Prostate Volume (PV), and the efficacy rate. The meta-analysis showed positive results for the use of moxibustion plus acupuncture therapy in terms of IPSS, QOL, and the efficacy rate. Conclusions: This meta-analysis of clinical trials suggests that moxibustion is effective intreating BPH patients. The results of this study could be applied to clinical treatment of BPH. However, additional large-scale clinical researches should be conducted.

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.

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.

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.
