BACKGROUND/OBJECTIVES: Recently, herbal medicines have gained attention for the treatment of benign prostatic hyperplasia (BPH), a common disease in elderly men. In this study, we aimed to determine the effect of ethanol extract of Asparagi radix (EAR), which is traditionally used to treat various diseases, on BPH development using a testosteroneinduced BPH model.MATERIALS/METHODS: Testosterone propionate (TP)-treated Sprague–Dawley rats were used to establish a BPH model in vivo. EAR was orally administered along with TP, and finasteride was used as a positive control. All rats were sacrificed at the end of the experiment, and pathological changes in the prostate tissue and levels of key biomarkers associated with BPH pathogenesis were assessed. RESULTS: Oral administration of EAR significantly inhibited TP-induced BPH by reducing the prostate weight, lumen size, and epithelial thickness in a concentration-dependent manner. EAR also significantly abrogated the expression of 5α-reductase type 2 (SRD5A2), proliferating cell nuclear antigen, and prostate-specific antigen (PSA) induced by TP.Additionally, serum levels of testosterone, dihydrotestosterone, and PSA were elevated in the TP-induced group but decreased in the EAR-treated group. EAR also decreased the expression levels of the androgen receptor (AR) and its coactivators in TP-induced BPH model rats. CONCLUSION Our findings revealed that EAR protected against BPH by inhibiting 5α-reductase activity and AR signaling pathway, suggesting its potential for BPH treatment.

Background: Hand hygiene is considered the simplest and most cost-effective method of infection prevention. Regular observation and feedback on hand hygiene compliance are key strategies for its enhancement. This study evaluated the effectiveness of hand hygiene surveillance, including direct observation and feedback, by comprehensively analyzing the reported hand hygiene compliance within the Korean National Healthcare-Associated Infections Surveillance System from 2019 to 2022. Methods: Participating medical institutions included general hospitals and hospitals with infection control departments that consented to participate. Hand hygiene surveillance was conducted using direct observation. Collected data, including healthcare workers, clinical areas, hand hygiene moments, and hand hygiene compliance, were recorded to calculate hand hygiene compliance rates. Additionally, the volume of alcohol-based hand sanitizers used per patient per day was investigated as an indirect indicator of hand hygiene compliance. The study was conducted from July 2019 to December 2022. Results: Hand hygiene compliance increased from 87.2% in Q3 2019 to 89.9% in 2022. Nurses and medical technologists showed the highest compliance rates, whereas doctors showed the lowest compliance rates. Intensive care units excelled in compliance, whereas emergency de partments lagged. Compliance was highest after patient contact and lowest when the patient’s surroundings were touched. Larger hospitals consumed more alcohol-based hand sanitizers than smaller hospitals did. Conclusion This study confirmed an improvement in hand hygiene compliance through sustained surveillance, indicating its contribution not only to preventing infection transfer within healthcare facilities but also to fostering a culture of hand hygiene in the country.
