Human diphyllobolthriasis is chiefly caused by infection with Diphyllobothrium latum(D. latum) through eating raw or unproperly cooked fish such as salmon, trout or perch. D. latum is worldwidely distributed, but not a common parasite of humans, and its prevalence in Korea is not high. The first worm-proven case of D. latum infection was first reported in 1971 and about 30 cases have been reported in Korea until now. However, with the increasing popularity of eating raw salmon, trout and perch, this tapeworm infection tends to increase in Korea. Most of the patients infected by D. latum have not showed the specific symptoms and only non-specific gastrointestinal symptoms(anorexia, nausea, vomiting, diarrhea, abdominal pain). We report a case which includes a chain whitish, threadlike tapeworm segments spontaneously discharged in the patients stool. On reviewing the literature, the present case is the first report of D. latum infection by eating cultured salmon. The patient was treated with 600mg single dose of Praziquantel.

BACKGROUND: Recently in Korea, the rate of addictive drug abuse is rapidly increasing in men on salary, housewives, and even in adolescents, who have been considered to be free from drugs, which presents a serious problem to the society. Especially, the habituation to gateway drug, such as cigarettes and alcohol, before 15 years old, would lead to the increased possibility of other drug abuse, including illicit drugs. Thereupon in this study, we intended toreview the effect of adolescents smoking an the drug abuse and deviated behaviors. METHODS: On September, 1997, randomly selected were 12 classes, an the basis of 2 classes per grade, from the two schools which was located each in Seoul and Buchean. And survey was dane on 610 students with non non-nominl, self-reported questionnaire. RESULTS: The rate of adolescent smoking was 28.1% in male students and had increasing tendency of "the higher the grades, the higher the smoking rate"(17.0% in the 1st gade, 31.5% in the 2nd grade, 35.9% in the 3rd grade). The smoking rate of female students was 12.3%. From the 2nd grade of middle school to the 2nd grade of high school was the critical period when the smoking habit was initiated in almost 90% of the students. The experiencing rates of drug abuse in studied subjects were as follows : drinking(79.0%), stimulants(4.8%), sedatives(4.1%), hypnotics(3.1%), glue sniffing(1.5%), butane gas(0.7%), marijuana/hemp(0.2%). They were higher in the smoking group than in the nansMoking group, showing statistical significances in most items except hypnotics and marijuana/hemp. Also simihr results were shown in deviated behaviors between the groups. CONCLUSIONS: With the concerted efforts of family, school, society and natian, we as family physicians should make efforts to delay and prevent adolescent's smoking, which is a gateway to drug abuse and deviated behaviors, and to increase people's recognition of health risks caused by smoking, and to provide proper program for adolescents to stop smoking.

Obesity is one of the well-known risk factors of breast cancer. We evaluated the relationship between serum adiponectin and resistin levels and breast cancer risk in 41 biopsy-proven breast cancer patients and 43 age- and body mass index-matched controls. The mean serum adiponectin level was lower in the breast cancer group than the control group (6.93+/-3.2 microgram/mL, vs. 7.60+/-3.5 microgram/mL), but this difference did not reach statistical significance (p=0.37). There was a statistically significant difference in serum resistin levels between the groups (breast cancer group 5.23+/-6.9 ng/mL vs. control 1.46+/-2.0 ng/mL; p<0.001). The risk of breast cancer was significantly increased in the highest tertile group for serum resistin level compared to the lowest tertile group (adjusted odds ratio 2.77 [95% CI 1.40-5.50]). The lymph node metastasis was significantly increased in the patients with less than the median adiponectin level (p=0.017). In the patients whose resistin level was higher than the median, the frequency of tumor with the highest histological grade was significantly increased (p=0.025). In conclusions, both the low serum adiponectin levels and high resistin levels are likely to be associated with increased breast cancer risk in Korean women.

7.Effects of Nano-sized Calcium on Intestinal Absorption and Bone Turnover
Journal of Korean Society of Osteoporosis 2011;9(1):107-114
OBJECTIVES: We compared the effects of two different nano-sized calcium supplements (synthesized by wet-chemical method or the dry-grinding method of calcium carbonate) and one micro-sized calcium supplement (calcium carbonate) on intestinal absorption and bone turnover in 20 young women. MATERIALS & METHODS: This study was carried out with a three week cross-over design. The subjects ingested one of three different calcium supplements (1 dose of 500 mg Ca++) at 8 AM, which was repeated three times weekly. Serum and urine samples were collected before and after the calcium load using a time table (serum sampling 0, 2 hr, 4 hr, 8 hr after loading; urine sampling 0, 4 hr, 8 hr after loading). RESULTS: Serum ionized calcium and parathyroid hormone concentrations significantly changed in response to all calcium supplements loading, the difference among calcium supplements was not significant. However, the postload urinary excretion of calcium and the N-telopeptide/creatinine ratio were significantly different among three calcium supplement over time by repeated measured ANOVA. CONCLUSIONS: The results of this study suggest the effect of nano-sized calcium supplements synthesized by the wet-chemical method is superior to the other calcium supplements in intestinal calcium absorption and bone turn-over.

BACKGROUND: Tsutsugamushi disease, which is caused by Orientia tsutsugamushi, is an acute febrile illness transmitted by infected mites. Recently, the incidence rate has been increased especially in the Daejeon and Chungcheongnam-do. We analyzed the patients with tsutsugamushi disease, who lived in Daejeon and Chungcheongnam-do, to find out their clinical manifestations and factors affecting the disease duration. METHODS: A total of 102 patients who were diagnosed with tsutsugamushi disease at the department of family medicine in a university hospital from September 2005 to November 2005 were studied. We analyzed their clinical characteristics and investigated the clinical factors associated with disease duration in tsutsugamushi disease by multiple regression analysis. The term "disease duration" was defined as the interval from symptom onset to discharge. RESULTS: Among 102 patients, 33 were males and 69 were female, and the mean age was 57.4 years. The average interval from symptom onset to admission was 6.6 days. The average interval from symptom onset to discharge was 14.5 days. From multiple regression analysis, interval from symptom onset to admission (beta=0.470, P<0.001), serum albumin level (beta=-3.441, P= 0.019), and abnormal findings of chest X-ray (beta=2.925, P=0.021) were shown to independently contribute to disease duration (R(2)= 0.458). CONCLUSION: Disease duration is significantly correlated with clinical factors such as abnormal findings of the chest X-ray, lower serum albumin level, and longer interval from symptom onset to admission. These factors could be used as parameters of the severity of disease in patients with tsutsugamushi disease.

BACKGROUND: The aim of this study was to elucidate the relationship between nonalcoholic fatty liver disease diagnosed by ultrasonography and the metabolic syndrome defined by NCEP-ATP III criteria. METHODS: Sixty-nine adult male subjects with negligible alcohol consumption underwent an anthropometric and laboratory investigation. The ultrasound scan of the liver was performed to determine the presence and the severity of nonalcoholic fatty liver disease. RESULTS: Nonalcoholic fatty liver disease was diagnosed in 36 cases by ultrasound scan. According to the severity of nonalcoholic fatty liver, triglyceride, HDL- cholesterol, alanine aminotransferase, aspartate aminotrasnferase, fasting insulin level, HOMA-IR, and obesity related variables (body mass index, percent body fat, waist circumference) showed a significant difference. The independent variables which account for the severity of nonalcoholic fatty liver disease was waist circumference, and alanine aminotransferase which is a predictor of nonalcoholic steatohepatitis. The prevalence of metabolic syndrome was 41% vs 6.1% in nonalcoholic fatty liver group vs control group, respectively, and the odds ratio was 11.1 (95% CI 2.29~53.6). The prevalence of nonalcoholic fatty liver was increased with increasing the number of features of metabolic syndrome. CONCLUSION: Nonalcoholic fatty liver disease was closely related to the metabolic syndrome and the severity classification of nonalcoholic fatty liver by ultrasound scan could be useful to predict of the severity of insulin resistance, and the risk of nonalcoholic steatohepatitis.

PURPOSE: Breast cancer has been reported as the most common cancer of women in the United States, Western Europe and Korea and about 210,000 and 10,000 women in United States and Korea every year, respectively are diagnosed with it. Breast cancer is curable with an early diagnosis, and many researchers have made efforts to find a marker for this malady, heat shock protein (HSP) consists of 6 groups, it is highly preserved throughout both the prokaryotic and eukaryotic cells and it acts as a molecular chaperone that's involved in protein folding. HSPs have been recently reported to be related with breast cancer. In this study, we investigated the changes of expression of HSP60 in tissues and cell lines of breast cancer. METHODS: We obtained breast cancer tissues and normal tissues from breast cancer patients, and we purchased several cancer cell lines from American tissue culture correction. We treated the tissues and the cell lines of human breast cancer with heat shock protein. Proteins and mRNAs were isolated from the tissues and the cells and then we performed Western blotting, reverse transcriptase-Polymerase chain Reaction and fluorescence activated cell sorter analysis on them. RESULTS: On Western blot, HSP60 was more overexpressed in the tissues and the cell lines of breast cancer than in the normal breast tissues and cell lines. The expression of HSP60 showed 2 types of molecular weight differences in the tissues and cell lines of breast cancer, and specifically, low HSP60 was over-expressed in the cancer tissues. There was no difference between the breast cancer cell lines and the normal cell lines in the expressions of HSP60 mRNA, according to the treatment with heat shock. Also, there was no relationship between phosphorylation and the structural difference of HSP60 protein, according to HSP60 protein's molecular weight. The expression of HSP60 has been mostly reported at the mitochondria; however, in this study, it was more predominantly detected at the cytoplasm than at the mitochondria in the breast cancer cell lines. CONCLUSION: We conclude that HSP60 may be used as a diagnostic marker for breast cancer. Detailed investigation of the usefulness and significance of the HSP60 expression as a prognostic factor is required in further studies.
