To determine the prevalence and risk factors of hypertension we performed cross-sectional study in a rural area. We measured BP and body mass index(BMI), and interviewed adult residents over 30-year-old age. 337 males and 357 females participated the survey. BP was checked twice and the mean was used to determine age and sex specific mean BP and prevalence of hypertension. Prevalence of definite hypertension(BP>or=160/95 or on medication) was 14. 0% in males and 17. 7% in females. Risk factor for hypertension was analysed by multiple logistic regression; age (10years: OR=l. 7) and BMI(1 BMI unit: OR=l. 2) were positively associated with hypertension but smoking(1 pack year: OR=0.9) was shown to have inverse relationship.

BACKGROUND: Superior migration of humeral head has been conventionally determined by measuring the acromiohumeral distance (AHD), We sought to devise a novel measurement system more reliably and accurately than AHD. We described a structural landmark called 'C-line'. In this study, we investigated the clinical usefulness of 'step-off of the C-line (SOC)' compared to that of AHD. METHODS: The C-line formed from the medial margin of the proximal humeral head continuing up to the inferior margin of the articular glenoid and then to the lateral border of the scapula. The superior migration of the humeral head triggered by a rotator cuff tear introduces a discontinuity in this C-line. We measured the distance of this discontinuity. We enrolled 144 patients who underwent a rotator cuff repair. We selected 58 controls who didn't have any cuff lesions apparent on magnetic resonance imaging. Using radiographs derived from standardized true anteroposterior views of the shoulder, we measured the SOC and the AHD. We used t-tests for statistical analyses. RESULTS: A rotator cuff tear was associated with an increase in SOC and a decrease in AHD. In control group, the mean SOC was 1.29 ± 1.71 mm and AHD was 9.71 ± 2.65 mm. In cuff tear group, the mean SOC was 3.15 ± 3.41 mm and AHD was 8.28 ± 1.76 mm. The mean SOCs of the patient group in relation to the mean SOC of the control group according to tear size, the SOCs of medium tear and lager groups showed statistically significant increase (p<0.05). CONCLUSIONS: The SOC may be a similarly effective to diagnose cuff tears of medium size and larger compared with AHD.

The cytolytic activity of CD4' T cells, both human and murine, has been clearly demonstrated in the immune response to mycobacterial infection and suggested to play a significant role in the protection and immunopathology. However, Uttle is known about the differentiation of CD4' CTL. In order to address this issue, we examined the influences of some factors on the generation of CD4' CTL specific to mycobacterial antigens. After 7 days' stimulation of PBMCs from healthy tuberculin reactors with mycobacterial antigens, the cytolytic activity of purised CD4' T cells toward autologous macrophages infected with mycobacteria was measured by Cr release assay. First, we found that both of live M. tubeiculosis and soluble antigens (ST-CF) induced the cytolytic activity of CD4' T cells, although the inducibility of the former was slightly greater than the latter. Second, the cytolytic activity was maximally induced at the relatively low antigen concentration (0.2:1 bacteria:monocyte ratio or 0.5 mg/ml of ST-CF). Finally, in the presence of increasing amounts of neutralizing anti-IL-12 or anti-IFN-r MoAb, the cytolytic activity of CD4+ T cells was decreased in a dose-dependent manner. These results suggest that low dose of antigen, its particulate type give mycobacteria), IL-12, and IFN-r give some positive signals for the generation of CD4+ CTL.

Although ultrasonography replaced many invasive studies in biliary tract diseases, direct cholangiography does still play an important role in the diagnosis and management of choledocholithiasis. Endoscopoic retrograde cholangiography (ERC) is regarded as the best method in evaluation of exact extent of the disease and its frequent complication, cholangitis. Authors analysed 56 cases of choledocolithiasis diagnosed by ERC and compared these with ERC in 18 cases of normal, 22 cases of cholecystitis, 15 cases of clonorchiasis and 9 cases of parenchymal diseases of liver. The results are as follows; 1. ERC findings of choledocholithiasis are filling defects by stoneor stones, dilation of common hepatic as well as common bile ducts and findings of cholangitis. 2. ERC findings of cholangitis are dilatation of larger intrahepatic biliary radicles and acute peripheral tapering, decrease of arborization, increased or right angle branching pattern, straightening and rigidity as well as irregular narrowing of intrahepatic biliary trees. This findings are observed in majority of choledocholithiasis. 3. Over9mm in diameter at intraprancreatic portion of common bile duct was regarded as abnormal, with 95% sensitivity,85% specificity and 91% diagnostic accuracy by decision matrix analysis. 4. In the presence of dilatation of CBD and findings of cholangitis in ERC, one should consider choledocholithiasis in spite of absence of stone defect.

Condyloma acuminatum, a benign disease caused by a filtrable virus, occurs predominantly in the perianal andgenital areas. The lesions are noninvasive but are subject to recurrence. In rare instances, a more aggresive formof this disease, known as "giant condlyloma acuminatum" or "Buschke-Lownestein tumor", occures. In this form,infiltration of the lesion into surrounding structures takes place. This tumor has been reported to occurprincipally in the genitourinary tract. The authors experienced a cases of giant condyloma acuminatum originatingfrom rectum in 67 years old male patient which recurred 3 months after electrofulguration.
