OBJECTIVE: The purpose of this present study was to compare mouse embryo development in 3 commercial media and hatching competence of mouse embryo with or without enzymatic treatment. METHODS: Collected 375 mouse embryos were divided into three groups, and then cultured in IVF-20 (G2), Medicult IVF (M3), P-1 (blastocyst M), respectively. Three day mouse morulae were cultured in G2 media treated with pronase. The results were analyzed using Chi-square test, and considered statistically significant when p<0.01. RESULTS: The developmental rate of 2 cell mouse embryo after 72 hours was highest in IVF-20 (G2) among conventional 3 media. The hatching rate of mouse morulae was low when clultured in G2 media without pronase during 48 hours. However, it was higher when cultured in media treated with l mg/ml, 2.5 mg/ml, 5 mg/ml pronase, respectively. CONCLUSIONS: Using good media and digestion of zona pellucida with enzymatic treatment improve development and hatching rate of embryo. Therefore, implantation and pregnancy rate could be improved.

PURPOSE: World wide studies have reported many cases of the normal variants of the hepatic artery in healthy individuals. Unfortunately, there are few medical reports in Korea, this study presents the results and analysis of the anatomical variants in the hepatic artery. METHODS: This study analyzed the blood supply of the liver in 131 patients who had received hepatic angiography and superior mesenteric angiography from January 1996 to September 2003 at the Maryknoll general hospital. RESULTS: The hepatic artery pattern with a normal hepatic artery pattern was observed in 101 out of 131 cases (77.1%) ; the right and left hepatic arteries arising from the proper hepatic artery, which arising from the common hepatic artery. The normal variations in the hepatic artery pattern were observed in 30 out of 131 cases (22.9%) ; the replaced right hepatic artery arising from the superior mesenteric artery was observed in 14 out of 131 cases (10.7%). The replaced left hepatic artery arising from the left gastric artery was observed in 6 out of 131 cases (4.6%). The common hepatic artery arising from the superior mesenteric artery was noted in 4 out of 131 cases (3.1%). The accessory left hepatic artery arising from the left gastric artery was observed in 1 out of 67 cases (0.7%). Other variants were noted 5 out of 131 cases (3.8%). CONCLUSION: Knowledge of the patterns and frequency of the variants in hepatic artery is increasing with the larger number of national reports on the hepatic artery variants, which can be great help in surgical operations, hepatic arterial embolization, or liver transplant.

Background: To evaluate the drug prescription patterns for men diagnosed with benign prostatic hyperplasia (BPH) in Korea. Methods: We extracted the data of 3% of the national patient samples including men aged ≥ 40 years between 2012 and 2017 from the Health Insurance Review and Assessment database and investigated the drugs prescribed for men with the BPH code N40. Men with a diagnosis of BPH but not receiving treatment were excluded. The primary outcome was the drugs prescribed and the changes in drug prescription pattern over 6 years for men first diagnosed with BPH. Results: Alpha blockers were the most commonly prescribed drugs in men with BPH, and tamsulosin was the most common. The proportion of prescriptions increased steadily. The number of prescriptions for anticholinergics (ACH) increased, but decreased with the start of mirabegron prescriptions in 2015. Prescriptions of mirabegron are increasing rapidly and replacing ACH. Based on the prescription pattern by drug category, alpha blocker monotherapy decreased, whereas combination therapies such as alpha blocker + 5-alphareductase inhibitors (5ARI), and alpha blocker + 5ARI + ACH increased steadily. As for the number of prescriptions by drug ingredient, tamsulosin monotherapy was the most common, and the combination therapy of tamsulosin and mirabegron increased. Conclusion Alpha blockers were the most commonly prescribed drug for men first diagnosed with BPH in Korea from 2012 to 2017, and tamsulosin was the most common alpha blocker. Prescriptions of combination therapy and mirabegron are gradually increasing.

PURPOSE: Transurethral resection of prostate(TURP) is the gold standard for the treatment of benign prostate hyperplasia(BPH) at the present. But many attempts have been made to develop minimally invasive method. We studied the efficacy of transurethral needle ablation(TUNA) of prostate for treatment of BPH. MATERIALS AND METHODS: We performed TUNA in 20 BPH patients including 13 patients with acute urinary retention. Preoperatively all patients were evaluated using urinary flow rates, International Prostate Symptom Score(1-PSS), Quality of life and cystoscopic examination. The urinary flow rates, 1-PSS and Quality of life were checked at 1, 3 and 6 months after TUNA in all patients. RESULTS: The average value of peak flow rate of the patients with urinary retention were 10ml/sec, 12ml/sec and 13ml/sec at 1, 3 and 6 months follow-up. The average value of Qmax of the patients without urinary retention were 9ml/sec preoperatively and increased to 13ml/sec, 13ml/sec and 14ml/sec at 1, 3 and 6 months postoperatively. 1-PSS of patients with urinary retention improved from average 26 at preoperation to 14, 13, 10 at 1, 3 and 6 months postoperatively. Quality of life of patients with urinary retention improved from average 5 at preoperation to 2, 2, 2 at 1, 3 and 6 months postoperatively. The average value of patients without urinary retention improved from average 26, 5 at preoperation to 14, 11, 11 and 2, 2, 2 at 1, 3 and 6 months follow-up. No patients complained of erectile dysfunction and retrograde ejaculation postoperatively. CONCLUSIONS: The result of our preliminary study suggest that TUNA can be considered to be a simple, safe and efficacious procedure for the treatment of BPH including urinary retention.
