Bcl-2 oncoprotein is being localized to mitochondria and interfering with programmed cell death (apoptosis) independent of promoting cell division in the lymphoid and nonlymphoid cells. The bcl-2 oncoprotein expression has been reported in follicular lymphomas as well as in diffuse non-Hodgkin's lymphoma, leukemia and a variable propotion of Hodgkin's lymphoma cases. Recent evidence suggests that some lymphomas protected from apoptosis is conferred through expression of Epstein-Barr virus(EBV) latent membrane protein which turn to cause upregulation of bcl-2. To define the role of the bcl-2 oncoprotein and EBV in lymphoid malignancy, we tried immunohistochemical studies with anti-bcl-2 antibody and In situ hybridization (ISH) with EBV-encoded small nuclear RNAs(EBER) in the paraffin embedded sections of 46 non-Hodgkin's lymphoma (NHL) cases and 20 Hodgkin's lymphoma (HL) cases. Bcl-2 oncoprotein expression was found in 37 of 46 cases (80%) of NHL with relatively strong cytoplasmic staining, and in 14 of 20 cases (70%) of HL with weak cytoplasmic staining in limited small numbers of RS, Hodgkin and lacunar cells. The widespread presence of bcl-2 oncogene in many different types of both NHL and HL supports that the extended cell survival through overexpression of bcl-2 gene protein may be a growth advantage of neoplastic lymphoid cells. In the ISH analysis for EBV, the presence of EBV was detected in 17 of 20 cases (85%) of HL, compared to 6 of 44 cases(13.6%) of NHL. It appears to be no direct correlation between overexpression of bcl-2 oncoprotein by neoplastic lymphoid cells and the presence of EBV in NHL but it seems to be a definite association between EBV and HL.
3.The Mediating Role of Smoking and Body Mass Index on the Relationship between Alcohol Consumption and Blood Triglyceride Levels among Korean Adults: The 7th Korean National Health and Nutrition Examination Survey
Korean Journal of Health Promotion 2021;21(4):167-174
Background:
Although there are many studies of association between alcohol consumption and hypertriglyceridemia with categorized variables, it is insufficient to study association between quantity of alcohol consumption and triglyceride levels as continuous variables. Therefore, this study investigates direct effect of alcohol consumption on triglyceride levels. Additionally, this study examines indirect effects through smoking and body mass index (BMI).
Methods:
This study uses data from the 7th Korean National Health and Nutrition Examination Survey. Among the participants, 5,867 adults ≥20 years of age are enrolled. To test the association between quantity of alcohol consumption and triglyceride levels and indirect effects through smoking and BMI, this study conducts multi-regression analysis by SPSS PROCESS macro.
Results:
The results are as follows. First, alcohol consumption has positive(+) effects on smoking, BMI, and triglyceride levels significantly. Second, smoking and BMI have a positive(+) effect on triglyceride levels significantly. Third, alcohol consumption has positive(+) effects on triglyceride levels through smoking and BMI indirectly.
Conclusions
Alcohol consumption has a direct effect on triglyceride levels, also has indirect effects through smoking and BMI positively.

Purpose:
The prevalence of nonalcoholic steatohepatitis (NASH) is increasing with the increasing prevalence of childhood obesity. Although NASH has a high risk of progression to liver fibrosis and cirrhosis, few studies have reported noninvasive markers for predicting hepatic fibrosis in children. This study aimed to evaluate and compare the diagnostic accuracies of serologic biomarkers and scoring systems for hepatic fibrosis in obese children with NASH.
Methods:
A total of 96 children were diagnosed with NASH based on liver biopsy findings and divided into two groups according to the degree of liver fibrosis: mild (stage 0–1) or advanced (stage 2–4). Clinical and laboratory parameters and serum levels of hyaluronic acid and type IV collagen were measured. The aspartate aminotransferase/platelet ratio index (APRI) and fibrosis-4 (FIB-4) score were calculated.
Results:
Among the noninvasive markers, only serum type IV collagen level and FIB-4 were significantly different between the two groups. The area under the receiver operating curve of each biomarker and scoring system was 0.80 (95% confidence interval [CI]: 0.70–0.90) for type IV collagen at an optimal cutoff of 148 ng/mL (sensitivity 69.8%, specificity 84.6%), followed by 0.69 (95% CI: 0.57–0.83) for APRI, 0.68 (95% CI: 0.56–0.80) for FIB-4, and 0.65 (95% CI: 0.53-0.77) for hyaluronic acid.
Conclusion
Type IV collagen as a single noninvasive serologic biomarker for hepatic fibrosis and FIB-4 as a hepatic fibrosis score are beneficial in predicting advanced hepatic fibrosis and determining proper diagnosis and treatment strategies before fibrosis progresses in obese children with NASH.

Dermatophytes infect the human hair, skin, nail and cause the dermatophytosis. The extracellular and intracellular proteinases of the dermatophytes commonly occur in the genus Trichophyton like T. rubrum, T. mentagrophytes, and T. granulosum. These enzymes play a prominent role in growth, multiplication and infection of the host tissue. Extracellular proteinases have been purified from the species of Trichophyton and Microsporum. We purified the proteinase partially from the culture filtrate of the Trichophyton tonsurans through Mono-Q and Superose 12 column and investigated its biochemical and enzymatic characters. The molecular size of the proteinase was estimated to be 41 kDa by SDS-PAGE. And pI was 3.2. The optimal temperature and pH for an enzymatic activity were 27C and 7.5, respectively. The purified porteinase degraded the keratin, bovine serum albumin, hemoglobin. The serine proteinase inhibitor like PMSF and DFP inhibited the proteolytic activity of the purified enzyme whereas the cysteinase inhibitor did not. These results demonstrated that the purified proteinase is a serine proteinase and can contribute the tissue invasion.

Precise bracket positioning is essential in modern orthodontics. However, there can be alterations in the vertical position of a bracket due to several reasons. The purpose of this study was to evaluate the effect of variations in the vertical bracket position on the crown inclination in Korean patients with normal occlusion. From a larger group of what was considered to be normal occlusions obtained from the Department of Orthodontics, College of Dentistry, Seoul National University, each of the final 10 subjects (6 males and 4 females, with an average age of 22.3 years) was selected. The dental models of each of the subjects were scanned three-dimensionally by a laser scanner, and measurements drawn from these were made on the scanned dental casts of the subjects were input into the computer program. From this the occlusal plane and the bracket plane were determined. The tooth plane was then constructed to measure the crown inclination on the bracket plane of each tooth. From a practical standpoint, information was obtained on the extent to which the torque of a tooth would be changed as the bracket position was to be moved vertically (in +/-0.5 mm, +/-1.0 mm, +/-1.5 mm) from its ideal position. A one way analysis of the variance (ANOVA) was used to compare each group of the different vertical distances from the bracket plane on a specific tooth. Duncan's multiple comparison test was then performed. There were statistically significant differences in the crown inclination among the groups of different vertical distances for the upper central incisor, upper lateral incisor, upper canine, upper first and second molars, lower first and second premolars, and lower first and second molars (p<0.05). On the upper anterior teeth, upper molars, lower premolars and lower molars, the resultant torque values due to the vertical displacement of the bracket were different depending on the direction of the displacement, occlusal or gingival. This study implies that the torque of these teeth should be handled carefully during the orthodontic treatment. In circumstances in which the bracket must be positioned more gingivally or occlusally due to various reasons, it would be useful to provide the chart of torque alteration of each tooth referred to in this study with its specified bracket prescription.
