The use of a pneumatic tourniquet is potentially associated with injury to underlying muscles, vessels, and nerves if excessive pressure occurs beneath the toumiquet. In order to minimize the risk of soft tissue injury, the lowest tourniquet pressure that maintains a bloodless operative field should be used. A clinical study was undertaken to evaluate the pneumatic tourniquet setting required for adequate hemostasis in upper extremity surgery. From March to September in 1984, the subcutaneous soft tissue pressure of the 20 upper extremities beneath a pneumatic toumiquet in the arm were measured directly and the following results were obtained. 1. The underlying subcutaneous soft tissue pressure was not affected by adult, age, arm circumference, and blood pressure of normal range. 2. The underlying subcutaneous soft tissue pressure showed direct correlation with the tourniquet pressure respectively. 3. A tourniquet preasure of more than 250 mmHg was not rarely required in a normotensive individual.

BACKGROUND/AIMS: Treatment of chronic hepatitis B with interferon results in a sustained loss of hepatitis B virus DNA and hepatitis B e antigen (HBeAg) and remission of liver disease only in a proportion of cases. Recently, mutations of hepatitis B virus (HBV) core gene have been reported as being related to the failure of interferon treatment in chronic hepatitis B. This study investigated whether core gene mutations of HBV are related to non-response to interferon therapy and whether the recurrence of HBeAg and HBV DNA in initial responders to interferon therapy is associated with the emergence of HBV core gene mutants. METHODS: The precore/core gene sequence was determined by polymerase chain reaction (PCR) and direct sequencing of PCR product in serum samples obtained before interferon treatment from 10 responders and 10 non-responders to interferon therapy. In addition, precore/core gene sequence was determined in serum samples obtained before interferon treatment and after recurrence from 10 patients who showed recurrence of HBeAg and HBV DNA after initial response to interferon therapy. RESULTS: In samples from 10 responders, there were 7 missense mutations and 71 silent mutations. However, there were 43 missense mutations and 109 silent mutations in samples from 10 non-responders. In samples obtained before interferon treatment from the 10 patients who showed recurrence after initial response, 8 missense mutations and 74 silents mutations were found. The nucleotide sequences from the samples obtained after the recurrence showed 6 silent nucleotide substitutions compared with the sequences from the samples obtained before interferon treatment. CONCLUSIONS: Mutations in the core protein of HBV occur more frequently in non-responders than responders to interferon therapy of chronic hepatitis B and may be a factor responsible for the failure of interferon treatment. The recurrence of HBeAg and HBV-DNA in initial responders to interferon therapy is not associated with the emergence of the HBV core gene mutants.

PURPOSE: This study aimed to investigate the effects of vasopressin and desmopressin on the contractile and relaxative responses of rabbit cavernosal smooth muscle. MATERIALS AND METHODS: Isometric tension studies were conducted to investigate the effects of vasopressin(10(-14)-10(-8)M) and desmopressin(10(-14)- 10(-8)M) on the contraction and relaxation responses of rabbits cavernous muscle strips in an organ bath. The effects of pretreatment with phenylephrine(10(-5)M), L-NAME(10(-5)M) and indomethacin(10(-5)M) on the contraction and relaxation responses of the vasopressin and desmopressin were also investigated. The statistics were analyzed by Student's t-test and ANOVA. RESULTS: Vasopressin contracted the strips in a dose-dependent manner, while desmopressin did not. The phenylephrine-induced contraction was dose-dependently increased by vasopressin, but it was dose-dependently relaxed by desmopressin. L-NAME pre-treatment did not block the relaxation response, but indomethacin pre-treatment did. Vasopressin- induced contraction occurred the via V(1) receptor, while desmopressin- induced relaxation occurred via the V(2) receptor. CONCLUSIONS: Vasopressin, in pathophysiological circumstances, would worsen erectile dysfunction. On the contrary, desmopressin, which may induce an endothelium-dependent relaxation of the cavernous smooth muscles, would be good for erectile function.

Recently the use of I-PSS (International prostate symptom score) is highly recommended for the evaluation of symptomatic benign prostatic hyperplasia (BPH) and many linguistic translations have been made. Regardless the validity and reliability of linguistic translation, there might be several social and cultural factors which affect to the symptom severity in BPH. We tried to show the prevalence of prostatism and the effect of social and cultural background which could affect to the results I-PSS questionnaire in Korea. A total of 841 men (40~79 years) who visited 4 health care center were included. Because of 107 men had medico-surgical history relating to voiding, final eligible subjects were 734. Total symptom scores increased by age decades (40~49, 50~59, 60~ 69, 70~79; median 7, 8, 11, 12 respectively). The rate of mild (0~7); moderate (8~19); and severe (20~35) symptom in 40th, 50th, 60th and 70th were 55.5%; 39.3%; 1.2%, 45.4%; 46.5%; 8.1%, 30.4%; 53.9%; 15.7% and 28.1%; 43.8%; 28.1% respectively. One cause of these high prevalence of prostatism in Korea is relatively very small proportion of readily treated BPH patients in general population (0.5%). Another factor of the high prevalence of prostatism is thought to be the different social and cultural concept to voiding status. These factors limit comparability of I-PSS questionnaire between different countries.

While T-cell non-Hodgkin's lymphoma (NHL) associated with hemophagocytic syndrome (HPS) has been frequently observed, B-cell NHL associated with HPS has been rarely reported. We report a case of hepatosplenic B-cell lymphoma associated with HPS in a 41-year-old woman who presented with fever of unknown origin. An abdominal CT scan revealed splenomegaly with focal splenic infarction. Splenectomy and a liver wedge biopsy showed sinusoidal-pattern infiltration of medium to large tumor cells with positive reaction to a B-lymphocyte marker. Findings on bone marrow examination showed proliferation of histiocytes with avid hemophagocytosis.

This study was designed to investigate the relationship between nutritional intake and caries experience of junior high school students. The sample consisted of 295 boys and 356 girls in Kangwha county. Dependent variables were total caries experience, occlusal surface caries experience, smooth surface caries experience and DMFS score (Decayed, Missing, Filling Tooth Surface score). Independent variables such as pit and fissure retentiveness of first molars, oral hygiene status, intraoral acidogenicity were also measured by dentists. Other independent variables such as toothbrushing habits, socioeconomic conditions, between-meal eating habits, and daily nutritional intake were determined during an interview. Univariate and multivariate analysis was performed to evaluate how nutritional intake influences caries experience. The results were as follows: 1. The most influential factor on dental caries experience was pit and fissure retentiveness. 2. Dietary fiber and potassium were the significant nutritional factors on total caries experience and occlusal caries experience, and niacin was the significant nutritional factor on smooth surface caries. 3. DMFS score was positively associated with the daily amount of carbohydrate and niacin intake, and negatively associated with total energy intake. The above results suggested that pit and fissure retentiveness was the most influential factor on caries experience. However, in this study, the intake of potassium and niacin was identified to influence the caries experience in addition to confirming the well-known relationship between fiber and carbohydrate intake.

PURPOSE: Hepatocellular carcinoma (HCC) is one of the most aggressive malignancies. Recently, the overexpression of programmed cell death 1 (PD-1) and PD-1 ligand 1 (PD-L1) has been shown to correlate with poor prognosis in many cancers. However, the expression of PD-L1 or PD-1 ligand 2 (PD-L2) and clinical outcomes have not been fully investigated in HCC. MATERIALS AND METHODS: Formalin-fixed paraffin-embedded samples were obtained from 85 patients with HCC who underwent surgery. The expression of PD-Ls (PD-L1, PD-L2) was evaluated by immunohistochemical analysis. RESULTS: The proportion of high expression groups of PD-L1 and PD-L2 was 27.1% and 23.5%, respectively. Univariate analysis revealed that tumor size (p < 0.001), histological differentiation (p=0.010), PD-L1 expression (p < 0.001), and PD-L2 expression (p=0.039) were significant prognostic factors of overall survival in patients with HCC. Multivariate analysis revealed that overall tumor size (hazard ratio [HR], 4.131; 95% confidence interval [CI], 2.233 to 7.643; p < 0.001 and HR, 3.455; 95% CI, 1.967 to 6.067; p < 0.001) and PD-L1 expression (HR, 5.172; 95% CI, 2.661 to 10.054; p < 0.001 and HR, 3.730; 95% CI, 1.453 to 9.574; p=0.006) were independent prognostic values for overall and disease-free survival. Patients with high expression of PD-Ls had a significantly poorer survival than those with low expression (p < 0.001, p=0.034). CONCLUSION: The overexpression of PD-Ls in HCC patients is correlated with survival and tumor recurrence. Further evaluation of PD-1 and PD-Ls as therapeutic targets and predictive biomarkers for HCC is warranted.
