BACKGROUND: Helicobacter pylori(H. pylori) has been implicated in the pathogenesis of chronic active gastritis and peptic ulcer disease. All patients with ulcers who are infected with H. pylori receive antimicrobial therapy. Therefore diagnosis of H. pylori infection is imperative for the treatment gastritis or ulcer patients. We evaluated the four diagnostic methods and three culture media for the isolation of H. pylori. MATERIALS AND METHODS: Rapid urease test(CLO test), modified Gram stain, culture, and nested polymerase chain reaction (PCR) were performed with 108 gastroscopic biopsy specimens from patients with peptic ulcer or chronic gastritis. Among them 40 specimens were inoculated onto each of 5% sheep blood agar, e99 Yolk emulsion (EYE) agar, and 7% horse blood agar containing antibiotics. RESULTS: The positive rates were the highest by the PCR(72%), 67% by modified Gram stain, 64% by CLO test, and 57% by culture. Among the three media the horse blood agar (selective medial) gave the highest isolation rate (48%), followed by sheep blood agar (45%), and EYE agar (38%). CONCLUSION: Though PCR was the most sensitive method for the detection H. pylori modified Gram stain was sensitive enough, simple, rapid, and economical as the routine diagnostic method of H. pylori. For the culture of H. pylori combination of sheep blood agar as nonselective media and horse blood agar as selective media would show the highest isolation rate.

BACKGROUND: Microlymphocytotoxicity test is most widely used for HLA Class l typing but almost all laboratories depend on imported HLA Class 1 typing trays. Matching criteria for the selection of HLA- matched platelets to treat platelet refractoriness is not as strict as for bone marrow transplantation. Therefore, with the acquisition of various antisera against high frequency HLA antigens, self-made HLA typing trays can be used for HLA typing of HLA-matched platelet donors. METHODS: 140 samples obtained during placental delivery were tested for the presence of HLA antibodies against a well-characterized panel of 90 cells. Specificity of HLA antisera were determined by evaluating the correlation coefficient r of the 2 x 2 table, x2 test. Antisera strength was evaluated by the strength index. RESULTS: HLA antibodies were detected in 25 samples by primary screening and 23 samples also showed a positive reaction in secondary screening(16%). Among 23 samples, 1 1 antisera were of reagent grade quality and 7 were monospecific antisera. DISCUSSION: Imported HLA typing trays can be replaced by harvesting HLA antisera against HLA antigens which are relatively common in Koreans through continuous HLA antibody screening using gushed out blood during placental delivery.

Klinefelter' syndrome is a disorder of sexual differentiation in males, characterized by the presence of two or more X-chromosomes, hypogonadism, and lack of secondary sexual characteristics. The association between Klinefelter' syndrome and glomerulonephritis has been reported, while cases of glomerulonephritis associated with Klinefelter' syndrome are rare. We report the Korean case: a 31-year-old man with Klinefelter' syndrome who developed glomerulonephritis. The patient's urine analysis shows microscopic hematuria and the result of kidney biopsy was minimal change disease. The onset and course of his disease might have been influenced by the sex hormone imbalance.

Total abdominal hysterectomy was considered an inadequate treatment method for invasive cervical cancer. Usually the procedure was inadvertently performed on patients who were thought preoperatively to have benign conditions. Survival for patients with gross disease remaining after inappropriate hysterectomy is poor. So, early cancer detection and proper management with precise pretreatment staging is necessary to avoid inadequate hysterectomy, especially in cases of gross residual disease. Cervical cancer typically recurs at the vaginal vault or in the pelvis; however it can recur distantly in the abdomen or lung. Although recurrences have been reported at laparoscopic trocar sites, it is unusual to have recurrence in the abdominal wall after laparotomy. A case of isolated metastasis to the abdominal wall after treatment of unexpected invasive cervical cancer found at total hysterectomy is presented with a brief review of the literature.

Graves' disease, the main cause of hyperthyroidism in the pediatric age group, is very rare in children younger than 4 years old but can seriously interfere with growth and development if not recognized and treated. Here we report a case of a 3-year-old girl with Graves' disease who presented with goiter, exophthalmos, heat intolerance, and hyperactivity. At her first visit, her serum concentrations of triiodothyronine (T3) and free thyroxine (free T4) were normal, whereas that of thyroid-stimulating hormone (TSH) was decreased. Antimicrosomal antibody was 7,053.94 IU/mL, and TSH-binding inhibitory immunoglobulin was 31.62%. A thyroid scan showed diffuse enlargement with markedly increased uptake of both thyroid glands. Although T3 and free T4 levels were initially normal, she developed hyperthyroidism 3 months later. She was finally diagnosed with Graves' disease and treated with methimazole for 6 months. This is the first report of Graves' disease in children younger than 4 years old in Korea.

To evaluate the efficiency of the diabetes mellitus screening program, the records of screening examinations for general workers and official workers at a general hospital in Taegu city were analysed. Six alternatives of the diabetes mellitus screening program were compared in terms of cost-effectiveness. The screening program I which was already used in the examination for general workers, screening program II for official workers, alternative program (A) which was the same method as screening program I without urine sugar test for the second examination in a hospital, a1ternative program (B) with the test for fasting blood sugar (FBS) in a worksite, alternative program (C) with the test for postprandial blood sugar (PPBS) in a worksite, alternative program (D) with the first test for FBS and the second test for PPBS of negatives for FBS test in a worksite, alternative program (E) with the first test for PPBS and the second test for FBS of negatives for PPBS test, and alternative program (F) with the test for urine sugar in a worksite. To compare the cost-effectiveness between alternatives, the cost (Won) per positive detected for diabetes mellitus (cost-effectiveness ratio) was calculated. The cost per positive detected was 37,767 Won for screening program I, 50,441 for screening program II, 37,433 for alternative program (A) , 27,645 for alternative program (B), and if it was assumed that the positive rate for negatives of FBS would be 2.0 %, 28,541 for alternative program (C) , 35,458 for alternative program (D) , 38,488 for alternative program (E) . However, that for alternative program (F) was varied with the positive predictive value (PPV) of urine sugar test for diabetes. The cost per positive detected was lowest(18,689 Won) when PPV was 93 %, whereas, highest (88,106) when PPV was 20 %. The critical value of PPV was 64 %. The alternative program (F) was most efficient when PPV was 64% or more. Considering the prevalence for diabetes mellitus, PPV for urine suger test, and feasibility of screening examination, alternative program (B) will be proved as the most efficient screening program. In conclusion, either program (B) or program (F) will be the most efficient method for screening a large population depending on the positive predictive value of fasting urine suger test.

This study was designed to evaluate the potential application of MRI in differentiating static blood from thrombus, age-related changes of thrombus and the signal differences of the intravascular thrombus in various pulse sequences. External jugular vein was ligated at both upper and lower ends to form a static blood column, and thrombin was injected into the column to cause venous thrombosis in a total of 15 mongrel dogs. The MR images were obtained with T1-and T2-weighted spin echo and gradient echo techniques, immediately after the formation of static blood and after 2 hour, 1 day, 1 week, 2 weeks and 4 weeks of the formation of thrombus at a 2.0T MR unit. The signal intensities of the thrombus and adjacent muscles were compared stubjectively, and the signal intensity ratio was compared objectively by the measurement of the signal intensities using a cursor. The MRI findings were compared with histologic findings. The signal intensities of static blood were hyperintense in all pulse sequences, and those of 2-hour, 1-day and 1-week-old thrombi were hyperintense in all pulse sequences. The number of experimental thrombi which showed isointensity on T1-and T2-weighted image, and hypointensity on gradient echo image increased as thrombi aged. The signal intensities of 2-week-old thrombus were isointense on T1-weighted image, hyperintense on T2-weighted image, and hypointense on gradient echo image, while those of 4-week-old thrombus were isointense on T1-weighted and T2-weighted image, and hypointense on gradient echo image in most experimental thrombi. There was a tendency to decrease in a signal intensity ratio as thrombi aged on T1-weighted, T2-weighted and gradient echo images(P<0.01) Histologically, thrombus was not formed and lumen was filled with many red blood cells(RBCs) in 2-hour-old specimen, but fibrin mesh was visible and RBCs decreased in number in 1-day-old specimen. In 1-week-old specimen, vessel was contracted and lumen was filled with thombus, RBCs, platelets, many fibrins and capillary-like strucrutes. The histologic findings of 2-week-old thrombus were similar to those of 1-week-old one except calcification. In 4-week-old specimen, vessels were contracted and lumen was obliterated with fibrosis and organization of the thrombus. Therefore, it is possible to diagnose thrombus, and to assess sequential changes of MRI findings of thrombus by using all pulse sequences, and these results can be essential bases for the interpretation of MR images of patients with venous thrombosis.

OBJECTIVES: Health-related quality of life (HRQoL) is an important outcome for middle school students. This study was designed to illustrate the effect of social support and class cohesiveness associated on HRQoL. METHODS: The subjects comprised 516 students from three middle schools in Daegu, South Korea that responded to a self-administered questionnaire in February 2014. The purposes of the questionnaire were explained to the subjects. RESULTS: The total mean of HRQoL was 81.1+/-15.3. Social functioning showed the highest score of 87.1+/-15.3 and emotional functioning showed the lowest score of 73.8+/-21.5. Teacher support (B=3.185, p=0.001) had a significant effect on the physical health summary scores. Class cohesiveness (B=2.237, p=0.022), friendships (B=5.102, p<0.001) and teacher support (B=2.498, p=0.006) had a significant effect on the psychosocial health summary scores. Finally, class cohesiveness (B=2.137, p=0.016), friendships (B=4.133, p<0.001) and teacher support (B=2.670, p=0.001) had a significant effect on the overall scores. CONCLUSION: The results of this study provide a basis for the development of strategies to improve health-related quality of life for middle school students, namely that relevant programs should be based on the improvement of social support and class cohesiveness.

Journal of Nutrition and Health 2023;56(6):615-628
Purpose:
Increasing levels of domestic fine dust (DFD) have emerged as a serious problem that threatens public health by causing chronic respiratory diseases and skin aging. The present study was performed to investigate the inhibitory effects of Gryllus bimaculatus (the two-spotted cricket), which has recently attracted attention as an edible insect in South Korea, on DFD-induced aging and inflammation.
Methods:
To verify that DFD causes skin aging and investigate the anti-aging effect of an aqueous ethanolic-Gryllus bimaculatus extract (AE-GBE), human diploid fibroblasts (HDF) were treated with 100 μg/mL of European reference material (ERM)-CZ100 dust for 24 hrs in the presence or absence of 100 μg/ml AE-GBE. Aging and cellular toxicities were assessed by measuring reactive oxygen species (ROS) levels, DNA fragmentation, and β-galactosidase activity. The protein levels of cyclooxygenase (COX) 2, matrix metalloproteinase (MMP)-1, and collagen were measured by western blot, and the mRNA expressions of inflammationrelated genes were assayed by quantitative reverse transcriptase polymerase chain reaction.
Results:
Treatment with ERM-CZ100 induced an aged phenotype in HDF cells, as evidenced by increased ROS levels, DNA fragmentation, and senescence-associated β-galactosidase activity, but cotreatment with AE-GBE significantly reduced these inductions. The mRNA expressions of pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α, induced by ERM-CZ100 were also reduced by AE-GBE cotreatment, which also reduced COX2 expression. Moreover, ERM-CZ100-induced MMP-1 expression and reduced collagen type I expression were recovered by AE-GBE treatment.
Conclusion
These results suggest that AE-GBE is a potential treatment for domestic fine dust-induced skin inflammation and inflammaging.
