BACKGROUND: Recently in Europe, some epidemiologic studies reported that various physical symptoms and social, psychological wellbeing are related to low blood pressure. But in Korea, none has been studied on symptoms related to low blood pressure yet. In this study, we would like to see if the somatic symptoms and social, psychological wellbeing shown t,o be related to low SBP is truly associated with it. METHODS: Questionnaire interview was done to the people who have visited Department of family practice in two university hospitals and two health promotion center from April, 1996 to August, 1996. Seven somatic symptoms and Psychosocial Wellbeing Index(PWI) for the evaluation of social, psychological health status were included in the questionnaire. SAS statistics packages was used in statistical precess. We used logistic regression to see the frequency of somatic symptoms related to the systolic blood pressure(SBP) group and the confirmation of confounding variables was done by ANOVA. RESULTS: Total of 304 completed the questionnaire. Average age was 44 years old and average SBP was 115.4+/-16.4. 84 of them (27.6%) felt that they had a low BP & 69 were women compared to 21 men, being meaningfully more common. 107(35.2%) people answered that they had heard that their blood pressure was low and 66% were from doctors. Only 32(38.1%) of the group who felt of having hypotensive symptoms and 38 of the group who heard of having hypotension actually had SBP of below 100 mmHg. Vocation, income, smoking & alcohol history, present illness, marital status were not significant as a confounding variable. SBP of 100 or below group had a less presentation of fatigue & significantly higher PWI than the group of above 100mmHg (p<0.05). The group who felt that they had a low BP had more complaints of fatigue, dizziness, palpitation, cold hands and feet and had significnatly higher PWI than the group who didnt. CONCLUSIONS: SBP of 100mmHg or below group has more frequent manifestion of fatigue and low level of sociopsycholgiacl health index than the above 100mmHg group. But most of the people who complained of hypotensive symptoms didnt have low blood pressure and a lot of them misunderstand of having low blood pressure and after checking blood pressure by doctors, so great deal of caution is called for when seeing patients.

GVHD (Graft-versus-Host Disease) results from the cytotoxic T lymphocytes from the bone marrow recognizing the recipient's minor histocompatibility antigens. In experimental murine models, either CD4+ or CD8+ T-cell subsets can cause GVHD, depending upon the particular strain combination utilized. Recent studies suggest that the keratinocyte undergo apoptosis in GVHD. However, morphological data supporting this concept are still lacking. The present study was undertaken in order to document apoptosis in experimental acute GVHD via sequential analysis of ultrastructure .Acute GVHD was produced across minor histocompatibility loci using appropriately matched murine strains. Acute GVHD was mediated with the use of highly purified preparations of donor CD4+ and CD8+ T-cell subsets. Whole T cells were used as a positive control and T cell depleted bone marrow as a negative control. Conventional transmission electron microscopy was used to define apoptosis structurally Sequential ultrastructure revealed that the keratinocyte underwent apoptosis in CD4+, CD8+ and whole T cell groups. This study demonstrates the sequential ultrastructure of the keratinocyte undergoing apoptosis from the beginning to the end. Both of the basal and the suprabasal keratinocytes show the morphology of early apoptosis, and the detachment of the tonofibril from the basement membrane and the adjacent cell was the general findings in the apoptotic cell Sequences of the cytoplasmic condensation was demonstrated . Through ultrastructural quantitation the apoptotic indices were depicted in all the experimental groups. Characteristically, numerous lymphocytes underwent apoptosis in CD8+ groups at day 28 and 35.

PURPOSE: The aim of this study was to evaluate the efficacy of a daily dose of tadalafil 5 mg as well as its safety for the cardiovascular system in men with erectile dysfunction. MATERIALS AND METHODS: This study included a total of 162 men who were administered a daily dose of tadalafil 5 mg between April and December of 2009. A total of 127 men completed the 8-week clinical trial. The International Index of Erectile Function (IIEF)-5, blood pressure, and heart rate were measured before treatment with tadalafil (V1) and 4 (V2) and 8 weeks (V3) after treatment with tadalafil. Adverse effects were assessed at V1, V2, and V3. In cases in which the International Prostate Symptom Score (IPSS) was > or =8 at V1, maximal flow rate (Qmax) and postvoid residual volume (PVR) were measured. RESULTS: The IIEF-5 values were 11.25+/-3.18, 14.56+/-3.79, and 16.91+/-3.56 at V1, V2, and V3, respectively, with significant improvement (V1 vs. V2, p<0.001; V1 vs. V3, p<0.001). The IPSS values were 10.59+/-5.56, 9.07+/-6.06, and 8.15+/-6.10 at V1, V2, and V3, respectively, and the differences were statistically significant (V1 vs. V2, p<0.001; V1 vs. V3, p<0.001). There were no significant differences in blood pressure or heart rate. Adverse effects were observed in 7 men (5.51%) at V2 and in 5 men (3.94%) at V3. CONCLUSIONS: Tadalafil 5 mg administered once-a-day may be effective in improving erectile function. Adverse effects on the cardiovascular system may be minimal. In addition, it is believed that this may also be effective in improving voiding symptoms.

A thermal neutron beam facility utilizing a typical tangential beam port for Neutron Capture Therapy was installed at the HANARO, 30 MW multi-purpose research reactor. Mixed beams with different physical characteristics and relative biological effectiveness would be emitted from the BNCT irradiation facility, so a quantitative analysis of each component of the mixed beams should be performed to determine the accurate delivered dose. Thus, various techniques were applied including the use of activation foils, TLDs and ionization chambers. All the dose measurements were performed with the water phantom filled with distilled water. The results of the measurement were compared with MCNP4B calculation. The thermal neutron fluxes were 1.02E9 n/cm2 s and 6.07E8 n/cm2 s at 10 and 20 mm depth respectively, and the fast neutron dose rate was insignificant as 0.11 Gy/hr at 10 mm depth in water. The gamma-ray dose rate was 5.10 Gy/hr at 20 mm depth in water. Good agreement within 5%, has been obtained between the measured dose and the calculated dose using MCNP for neutron and gamma component and discrepancy with 14% for fast neutron flux. Considering the difficulty of neutron detection, the current study support the reliability of these results and confirmed the suitability of the thermal neutron beam as a dosimetric data for BNCT clinical trials.

PURPOSE: In cases of patients who underwent bipolar hemiarthroplasty (BPHA) for treatment of a pertrochanteric fracture, we compared and analyzed the amount of blood loss and complications between a group using the cemented stem and a group using the cementless stem. MATERIALS AND METHODS: A total of 104 patients who underwent BPHA for treatment of a pertrochanteric fracture in our hospital for three years and 10 months (From January 2008 to October 2011) were included in this study. Among the 104 patients, 64 patients with a cemented stem were categorized into group 1, and the other 40 patients with an uncemented stem were categorized into group 2. Before surgery, the type of stem was determined by the bone quality of the proximal femur, which had been evaluated with a simple X-ray. Then, after surgery, the amount of blood loss and complications were compared between the two groups. RESULTS: Expected blood loss during the operation was 389.8 cc in group 1, and 395.3 cc in group 2(P=0.88). Postoperatively, average drained blood loss was 219.6 cc in group 1, and 338.1 cc in group 2. Cemented stem was associated with significantly less blood loss (P=0.004). The average operation time in group 1 and in group 2 was 96 minutes and 72 minutes. There was no significant difference in operating time (P=0.85). In addition, there was no difference in INR (International Normalized Ratio) and BMI (Body Mass Index) (P=0.28 and 0.08) regarding total amount of postoperatively drained blood loss. There was no occurrence of hypotensive shock or fatal pulmonary embolism in either group. Three cases of periprosthetic fracture occurred in group 2. CONCLUSION: Fewer occurrences of postoperative blood loss and fewer complications were observed in the cemented stem group than in the cementless stem group. Preoperative evaluation of bone quality and use of the cement stem for patients with poor bone quality may be a good treatment method that can help to reduce complications.

BACKGROUND: Various combinations of treatment modalities have been reported in stage III non-small cell lung cancer (NSCLC), however, the standard treatment modality has not established yet. Recently, the efficacy of concurrent chemotherapy and radiation therapy has been reported in locally advanced lung cancer. We evaluate the response rate, toxicity, arid survival of concurrent chemotherapy with etoposide and cisplatin(EP) arid radiation therapy for unresectable stage III NSCLC. METHODS: Between October 1995 and December 1996, 32 patients with histologically proven unresectable stage III NSCLC without, malignant pleural effusion were entered into this study. Twenty-nine patients were eligible for the response, survival, and toxicity analysis. Induction was two cycles of chemotherapy with etoposide arid cisplatin plus concurrent chest RT to 4500cGy. Resection was attempted if the clinical response offered surgical resectability. Boost radiation therapy upto 5940cGy and one cycle of EP were performed if the disease were stable or responsive but still unresectable. RESULTS: Of 29 eligible patients, 22(75.9%) showed partial response(PR). The progression free interval was 6.3months(range 1.1 to 19.5months). Surgical resection was performed in one patient The median survival was l2.1months and one-year survival rate was 50.6%. The major toxicity was leukopenia(> or = grade 3,46%) Thrombocytopenia over grade 3 was found in 1%. Radiation pneumonitis occurred in 13 patients(46%). CONCLUSION: Concurrent chemotherapy(EP) pins radiotherapy was effective and tolerable in the treatment of unresectable stage III NSCLC.

PURPOSE: Up to 10% of recurrences develop beyond 5 years after curative treatment of localized renal cell carcinoma (RCC). Clinicopathologic features were evaluated to determine which factors are associated with late recurrence. MATERIALS AND METHODS: A total of 753 patients were diagnosed with localized RCC from January 2000 to June 2008. We enrolled 225 patients who were treated surgically and had a minimal recurrence-free survival of 60 months. Patients who had recurrence beyond 5 years after nephrectomy were defined as the late recurrence group and the remaining patients as the recurrence-free group. Multivariate logistic regression analyses and the Cox proportional hazard model were used for determination of features associated with late recurrence. RESULTS: In multivariate analyses, age older than 60 (p=0.030), Fuhrman grade > or = 3 (p=0.042), and pT stage > or = pT2 (p=0.010) showed statistical association with late recurrence. The Cox proportional hazard model showed significant differences in recurrence-free survival when we classified the patients based on pT2 (p=0.007) and on patient age > or = 60 years (p=0.039). CONCLUSION: Patient age greater than 60 years, Fuhrman grade > or = 3, and tumor stage > or = pT2 are independent risk factors of recurrence more than 5 years after surgery in patients with RCC. Therefore, close lifelong follow-up is recommended for patients with these risk factors.

PURPOSE: To predict the malignant potential of prostate cancer (PCa) according to prostate-specific antigen velocity (PSAV), PSA density (PSAD), free/total PSA ratio (%fPSA), and digital rectal examination (DRE). MATERIALS AND METHODS: From January 2009 to December 2012, 548 adult male patients were diagnosed with PCa by prostate biopsy at four hospitals in Korea. We retrospectively analyzed 155 adult male patients with an initial PSA level < or =10 ng/mL and whose PSA levels had been checked more than two times at least 6 months before they had been diagnosed with PCa, with test intervals of more than 3 months. Patients with a urinary tract infection, and patients who had previously undergone cystoscopy or surgery of the prostate were excluded. We separated patients into two groups according to Gleason sum [Gleason sum < or =7 (n=134) or Gleason sum > or =8 (n=21)] and the presence of extracapsular invasion [organ confined (n=129) or extracapsular invasion (n=26)]. Differences between the groups were compared. RESULTS: The group with a Gleason sum > or =8 or extracapsular invasion of PCa showed high PSAV and significantly lower %fPSA. There were no significant differences in PSAD and the presence of an abnormality on DRE between two groups. CONCLUSION: In PCa patients treated with other therapies besides prostatectomy, a high PSA velocity and a low %fPSA may predict high grade PCa with a Gleason sum > or =8 or the presence of extracapsular invasion.
