This study was conducted to investigate the effects of Tissue Culture Medium 199 (TCM) and Dulecco's Modified Eagle Medium (DMEM) on the blastulation and grade of human oocytes on Vero cells in vitro. A cohort of 79 and 93 oocytes in metaphase II stage were used in TCM 199 and DMEM respectively. No differences were found in the nurser of oocytes showing two-pronuclei between TCM (82.3%) and DMEM (86.0%). The number of fertilized oocytes reaching the blastocyst was not significant in TCM (60.0%) and DMEM (63.1%).4 total of 89 blastocysts were categorized into the four grades (BG1, BG2, BG3 and early) depending on their morphology. The number of embryos achieving the blastocyst grade 1 (BG1) was significantly higher (p<0.05) in DMEM (50.8%) than TCM (15.0%). It is concluded that cultured oocytes in DMEM with glutamine on Vero cells should be significantly increased BG1.

PURPOSE: The purpose of this study was to investigate the physiological index, anxiety and depression by the severity of lower urinary tract symptoms in patients with benign prostatic hyperplasia. METHODS: This research was conducted from the 4th to the 27th of May in 2016 on112 patients with benign prostatic hyperplasia. The data were analyzed using a chi-square test, ANOVA, and Pearson Correlation Coefficients. RESULTS: The results demonstrated a difference depending on the dysuria period of each lower urinary tract symptom, marital status, occupation and perceived health state of the patient. The physiological index by lower urinary tract symptoms showed a difference in the maximum flow rate, amount of post-void residual urine and Prostate-Specific Antigen (PSA), and anxiety and depression factors also revealed a difference. Lower urinary tract symptoms showed a positive correlation to the amount of post voided residual urine and PSA, a negative correlation to the maximum flow rate and also indicated a positive correlation to depression. CONCLUSION: The results of the study belonging to the moderate and severe categories were high when the result was based on the categorization of subjects with benign prostatic hyperplasia with lower urinary tract symptoms. Considering that depression levels increase as the symptom intensifies and the anxiety score is also high with mild symptoms, psychological support intervention is needed when a pattern of benign prostatic hyperplasia appears.

PURPOSE: Prolonged stay in the emergency department (ED) have been associated with high mortality, but this association remains controversial. We examined the relationship between emergency department length of stay (EDLOS) and the mortality in critically ill patients undergoing traumatic emergency surgery. METHODS: A retrospective cohort study was conducted at an academic medical center with 257 critically ill patients undergoing traumatic emergency surgery from 2003 to 2004. Patients were classified into two groups those spending less than 4 hours in the emergency department and those spending over 4 hours. The groups were compared for hospital-mortality, and the data were entered into multinominal logistic regression, ROC curve, and life table using 12.0 version of SSPS. RESULTS: The overall mortality rate was 16.0%. Average length of stay was 220.1+/-138.5 minutes and 191.3+/-112.9 minutes in the survivors and non-survivor groups, respectively (p=0.212). Hospital-mortality and cumulative survival rate were similar in the group spending less than 4 hours to those in the group spending over 4 hours. The mortality was mainly related to the severity of the patients' condition (SAPS II). CONCLUSION: EDLOS did not affect hospital mortality, and EDLOS of more than 4 hours was not associated with worse prognosis.

STATEMENT OF PROBLEM: Clinically, maxillary first premolar has a high risk of fracture. This is thought to be caused by the susceptible figure which the maxillary first premolar has. In other words, sharp cusp angles of the premolar is thought to influence this situation. PURPOSE: This study was to know stress distribution of all-ceramic crown according to the cusp angle. MATERIAL AND METHOD: It was manufactured a three dimensional finite element model simplified maxillary first premolar, and then analyzed stress distribution when cusp angle was each 80 degrees, 90 degrees, 100 degrees, 110 degrees and 120 degrees. RESULTS AND CONCLUSION: 1. The von Misses stress showed that stress decreases as cusp angle increases in the central groove of the occlusal surface. 2. It showed that maximum principal stress was centered at the region of the central groove of the occlusal surface and a region which the force was inflicted. And also it appeared high on the lingual and buccal side of finish line. 3. The X axis of normal stress was focused in the central groove of the occlusal surface. The Y axis normal stress appeared high in the central groove of the occlusal surface, buccal and lingual side. 4. The Stress near the finish line showed a low value compared with stress in the region of the central groove of the occlusal surface. 5. It shows that the most dangerous angle for tooth fracture was on 80 degrees of the cusp angle and low on 120 degrees of its.

Three groups of patients with newely diagnosed hypertension, or with hypertension not optimally controlled by previous treatment, completed a comparative study on the effects of Dihydrochlorothiazide, propranolol, and prazosin on plasma lipids after three months therapy. The drugs showed equipotent antihypertensive effects(P<0.01). Dihydrochlorothiazide administration was associated with a significant elevation of total cholesterol(42%, P<0.05), and triglyceride(8.1%, P<0.01). Changes of HDL-C(5.1%), LDL-C(3.3%), and cholesterol ratio(-4.8%) were not significant. Propranolol administration was associated with significant elevation of total cholesterol(3.8%, P<0.05), triglyceride(14.5%, P<0.005), and LDL-C(5.6%, P<0.005). Reduction of HDL-C(-7.8%, P<0.05) and cholesterol ratio(-14.7%, p<0.005) was also statistically significant. Prazosin administration was associated with significant decrease in total cholesterol(-6.6%, P<0.005), triglycride(-9.6%, P<0.005), and LDL-C(-11.7%, P<0.005), and significant elevation of HDL-C(10.6%,P<0.005) and cholesterol ratio(24.2%, P<0.005) was noted.

Arthroscopic treatment of shoulder instability involves two techniques mainly, transglenoid suture technique and anterior anchoring system. However, anterior anchoring system has some disadvantages such as limited indication, high cost, technical difficulty and incapability to suture or reconstruct for all types of Bankart lesion. Disadvantages of transglenoid suture techniques are indirect suture tie, bump effect and possibility of the suprascapular nerve injury. The authors use modified transglenoid suture technique (Rhees method) for shoulder instability involving Bankart lesion, type II SLAP lesion and capsular laxity. The purpose of this study is to accurately describe the relationship between the major neurovascular structures and the pinning sites used in transglenoid suture technique (Rhees method). Placement of two or three arthroscopic Beath pinning sites was simulated in four fresh cadaveric shoulder specimens by placing Steinman pins into the glenoid rim under open field. The specimens were then dissected and the relationship of the pinning sites to the suprascapular nerve and suprascapular artery were recorded. In Bankart lesion repair, safe zone of pinning sites were 2 and 5 oclock in two portals in right shoulder, safe zone of pinning sites were 7 and 10 oclock in two portals in left shoulder. Safe direction of pinning was as possible as inferomedial side in scapula. In type II SLAP repair, safe zone of pinning sites were 2 oclock and just above 2 oclock of glenoid in right shoulder and 10 oclock and just above 10 oclock of glenoid in left shoulder. Safe direction of pinning was pararell to glenoid cavity and slightly superior in horizontal plane. From this study, these sites and directions appeared to be safe. Proper pinning depends on careful attention to the topographical anatomy about the shoulder.
