PURPOSE: Atopy is a state of allergic response, mediated by IgE, to common environmental allergens. In recent decades, there has been an increase in prevalence of atopic disorders in children in developed countries. The factor associated with the rise of atopy incidence may be declining exposure to some infection opportunities. The aim of this study is to determine if the immune response to Mycobacterium tuberculosis can suppress atopy by investigating the association between tuberculin responses and serum IgE. METHODS: We divided the patients into two groups according to tuberculin skin test. Group A showed positive response (induration diameter > or =10mm), while Group B showed negative response (induration diameter< l0mm). A comparison was made between the two groups in terms of age, sex, serum total IgE and allergen-specific IgE. RESULTS: Twenty-one patients comprised Group A and 72 comprised Group B. The mean serum total IgE concentration and the number of patients showing positive MAST in Group B was significantly higher than that of Group A (P<0.05). CONCLUSION: In our study, there was an inverse association between delayed hypersensitivity to Mycobacterium tuberculosis and atopy.

PURPOSE: The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS: A retrospective study of patients receiving root-shaped screw-type dental implants placed from January 2000 to December 2009 was conducted. 6385 implants were placed in 3755 patients. The following data were collected from the dental records and radiographs: patient's age, gender, implant type and surface, length, diameter, location of implant placement, bone quality, prosthesis type. The correlations between these data and survival rate were analyzed. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. RESULTS: In all, 6385 implants were placed in 3755 patients (3120 male, 635 female; mean age 65 +/- 10.58 years). 108 implants failed and the cumulative survival rate was 96.33%. There were significant differences in age, implant type and surface, length, location and prosthesis type (P<.05). No significant differences were found in relation to the following factors: gender, diameter and bone quality (P>.05). CONCLUSION: Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival.

We reviewed the cases of five patients with colonic inertia who were treated with total abdominal colectomy and ileorectal anastomosis at the Wonkwang University Hospital from June 1994 to november 1995. All of the 5 patients with chronic constipation underwent, a colon study, colonoscopy, anorectal manometry, defecography, balloon expulsion test, and a study of the total and segmental colonic transit of radioopaque markers to diagnose the colonic inertia. The ratio of male to female was 1:4, the mean age 58 years, the average duration of symptom 41.8 months, and the average time between bowel movements 18.4 days. There was no specific operative morbidity and mortality and the average hospital stay was 14 days. At follow-up ranging from 3 months to 20 months they had excellent stool control and 1-2 bowel movements per 1-2 days. All were satisfied with the procedure.

BACKGROUND: As the mean life span is prolonged, the concern about health care in postmenopuasal women is now promoted. Expecially, osteoporosis is the serious health problem in postmenopausal women. Bone mineral density in postmenopause is controlled by that in premenopause. Therefore, we searched for the factors which contribute to bone mineral density in premenopause. METHODS: The study subjects who visited the Health Screening and Diagnosis Center in Yeungnam University Hospital from March 1998 to July 1999 was measured BMD at the lumbar spine using Dual Energy X ray Absorptiometry. Subjects were checked past medical history, life style(smoking, drinking, physical activity, exercise etc.), birth history, breast feeding, oral pill intake. The subjects who had disorders known to interfere with bone metabolism and premature menopausal and surgical menopausal women were excluded from the study. And we reviewed the results of the laboratory and radiologic findings which had done in Health Screening and Diagnosis Center. RESULTS: 352 women were included in this study. The number of normal BMD was 228 and the number of osteopenia was 124. Weight, height, BMI, exercise was significant positively correlated with bone mineral density(p<0.05). Previous operation history was significant negatively correlation with bone mineral density(p<0.05). Multiple logistic regression result showed that weight was the most significant factor affecting to BMD and the history of operation and exercise were significant factor affecting BMD(p<0.05). CONCLUSION: In postmenopausal women, who has low weight, past operation history and lack of exercise were need to evaluation of BMD and education for prevention of osteoporosis is needed.

BACKGROUND: Although pulmonary resection is the standard approach for the management of pulmonary metastases from soft tissue sarcoma, most of them are unresectable and chemotherapy remains the only option. The effectiveness of the cytotoxic drugs may be limited by the toxicities that occur before the therapeutic dose is reached. The regional administration of doxorubicin using pulmonary arterial perfusion in a rodent model can produce 10 to 25 times higher concentrations in the lung than systemic administration with minimal systemic toxicities. However, it is unclear whether a high concentration of doxorubicin has beneficial effects for killing cancer cells. MATERIAL AND METHOD: We studied this to evaluate the dose-dependent cytotoxic and apoptotic effects of doxorubicin on methylcholanthrene-induced rat fibrosarcoma(MCA) cells. This study examined the cytotoxicity and apoptosis-related gene expressions(Fas, FasL, Bax, caspase 1, caspase 2, caspase 8, Bcl-2, Bcl-xL, Bcl-xS) in MCA cells after 24 hours exposure to various concentrations of doxorubicin such as 1, 5, 10, 50, and 100 micrometer. RESULT: Dose-dependent cytotoxicity was observed after 24 hours exposure to doxorubicin. However, peak apoptosis after 24 hours exposure was observed at 5 micrometer of doxorubicin. Above 5 micrometer, apoptotic activity was decreased with dose-increment. All mRNA levels of apoptosis-related genes after 24 hours exposure were up-regulated above the control level at 1 micrometer of doxorubicin and then decreased by doxorubicin dose-increment except caspase 8, which showed higher levels than the control level at 5 micrometer. Apoptosis-related protein levels were highest at 1 micrometer of doxorubicin and then decreased by doxorubicin dose-increment. However, Bax and Bcl-xL proteins steadily showed higher levels than the control throughout the different concentrations of doxorubicin. CONCLUSION: These results suggest that apoptosis is the main cytotoxic mechanism in low concentrations of doxorubicin in MCA cells and apoptosis-related genes, such as Bax, caspase 8, a can kill MCA cells, even when apoptosis is inhibited, and have its propriety for achieving much cytotoxicity against MCA cells.

The distribution of GABA and/or glycine like immunoreactive nerve terminals on the soma of the masseteric gamma motoneurons were investigated using retrograde tracing of WGA-HRP (wheat germ agglutinin conjugated horseradish peroxidase) and postembedding immunogold labeling methods in serial ultrathin sections. Quantitative analysis of 140 nerve terminals apposing on somata of gamma motoneuron size less than 21 mm in average diameter was performed. The results obtained were as follows. 1. Synaptic covering % of apposing nerve terminals was 21.45+/-11.48% and packing density was 12.85+/-6.17. 2. Nerve terminals immunoreactive (IR) to GABA or glycine were F type containing pleomorphic vesicles with round shape predominant. Majority of nerve terminals immunonegative to GABA or glycine were S type containing spherical vesicles and few of them were F type. 3. 11.42+/-10.00% of examined nerve terminals were IR to GABA only, and 12.71+/-9.85% were IR to GABA and glycine, and 15.21+/-9.58% were IR to glycine only. 4. Synaptic covering % of nerve terminals IR to glycine only was highest (4.58+/-4.50%), followed in order by GABA and glycine (3.18+/-2.77%), and GABA only (2.38+/-2.06%). 5. Among all terminals, immunonegative nerve terminals (60.66+/-14.65%) were much more than nerve terminals immunoreactive to GABA and/or glycine (39.34+/-14.65%) These results show that inhibitory synaptic input and synaptic organization of the masseteric gamma motoneurons reveal characteristic features in contrast to that of alpha motoneurons and which may correlated to the electrophysi-ological characteristics of masseteric gamma motoneurons.

OBJECTIVE: Our purpose was to compare the clinical efficacy of intravaginal misoprostol and that of intravenous sulprostone for termination of second-trimester pregnancy. METHODS: The patients were assigned to misoprostol and sulprostone group, and the misoprostol group was further divided into two groups according to gestational age. In the misoprostol group, the patients at or before 20 weeks of gestation received 400 microgram of intravaginal misoprostol every 4 hours until labor pain was established, 200 microgram every 6 hours after 20 weeks of gestation. In the sulprostone group, intravenous sulprostone was infused at the speed of 100 microgram/hr after cervical ripening with 3 mg of intravaginal dinoprostone. RESULTS: At or before 20 weeks of gestation, the median time from induction to completion of termination was longer, but the success rate within 24 hours was less in the misoprostol group than in the sulprostone group (18.75 vs. 7.15 hours, p=0.015; 50% vs 92%, p=0.014, respectively). After 20 weeks, there was no significant difference in median induction time or success rate within 24 hours (5.54 vs. 8.0 hours, p>0.05; 100% vs. 100%, p>0.05, respectively). There was no significant difference in the prevalence of complication or change of hemoglobin after termination between two groups. CONCLUSION: Sulprostone may be more effective for termination of pregnancy at or before 20 weeks of gestation and misoprostol may be as effective as sulprostone after 20 weeks of gestation. But considering less cost and complication, the efficacy of misoprostol should be further investigated for termination of second- trimester pregnancy.

OBJECTIVES: This study was conducted to propose the need of re-establishing the criteria of the body weight classification in the elderly. We compared the Asia-Pacific Region Criteria (APR-C) with Entropy Model Criteria (ENT-C) using Morbidity rate of chronic diseases which correlates significantly with Body Mass Index (BMI). METHODS: Subjects were 886 elderly female participating in the 2007-2009 Korea National Health and Nutrition Examination Survey (KNHANES). We compared APR-C with those of ENT-C using Receiver Operating Characteristics (ROC) curve and logistic regression analysis. RESULTS: In the case of the morbidity of hypertension, the results were as follows: Where it was in the T-off point of APR-C, sensitivity was 67.5%, specificity was 43.1%, and Youden's index was 10.6. While in the cut-off point of ENT-C, it was 56.7%, 56.6%, and 13.3 respectively. In the case of the morbidity of diabetes, the results were as follows: In the cut-off point of APR-C, Youden's index was 14.2. While in the cut-off point of ENT-C, it was 17.2 respectively. The Area Under the ROC Curve (AUC) of the subjects who had more than 2 diseases among hypertension, diabetes, and dyslipidemia was 0.615 (95% CI: 0.578-0.652). Compared to the normal group, the odds ratio of the hypertension group which will belong to the overweight or obesity was 1.79 (95% CI: 1.30-2.47) in the APR-C, and 2.04 (95% CI: 1.49-2.80) in the ENT-C (p > 0.001). CONCLUSIONS: We conclude that the optimal cut-off point of BMI to distinguish between normal weight and overweight was 24 kg/m2 (ENT-C) rather than 23 kg/m2 (APR-C).
