Objective Detection of S-100B protein in different degree meconium pollution level in serum of children with value.MethodsIn 2012 June to 2013 December in our department were simple meconium stained amniotic fluid in term newborns in 73 cases, and set up for the observation group, and according to the amniotic fluid pollution degree is divided into 47 cases of amniotic fluid of Ⅰ-Ⅱdegree pollution group and 26 cases in grade Ⅲmeconium group during the same period, selected 20 cases without amniotic fluid contamination in term healthy newborns for the control group, the groups were compared in S-100B protein content difference.ResultsⅢmeconium stained amniotic fluid were within 6h serum S-100B was significantly higher than that in control group(P<0.01), and the degree of contamination of amniotic fluidⅠ-Ⅱgroup compared with the control group, no significant difference(P>0.05).Ⅲ meconium stained amniotic fluid in children with 72h also increased.ConclusionThird degree meconium stained amniotic fluid but normal Apgar score of newborns may still exist in clinical brain injury, so pay close attention to.

PURPOSE: MEN1 gene mutation causes multiple endocrine neoplasia type 1. It also suggests that somatic MEN1 gene mutation plays a role in sporadic endocrine tumor. In this study, we examined whether somatic mutations of MEN1 gene are responsible for sporadic parathyroid tumors and correlate with clinical manifestations of parathyroid tumors. METHODS: Somatic mutation of MEN1 gene in the formalin-fixed, paraffin-embedded parathyroid tumor tissue from 8 adenomas, 2 carcinomas and 1 hyperplasia were analyzed by direct sequencing. Clinicopathological parameters were reviewed from medical records and compared with the mutational data. RESULTS: Eight of eleven (73%) sporadic parathyroid tumors had somatic MEN1 mutations of 14 different types. In the 14 types, 13 were a point mutation which is composed of 8 missense mutations, 2 nonsense mutations and 3 silent mutations. One of 14 types is a frameshift deletion of 27 base pairs in exon 2. Somatic mutation was frequent in the exon 2 and exon 10. Four types of polymorphism were found. There was no correlation between the presence of mutations and clinicopathological phenotype of parathyroid tumors. CONCLUSION: This result suggests that somatic mutation of MEN1 gene plays a definite role in sporadic parathyroid tumor formation.

Strumal carcinoma of the ovary is rare tumor of germ cell origin characterized by intimate mixture of thyroid tissue and carcinoid. We report a strumal carcinoid tumor associated with ipsilateral follicular cyst and contralateral mature cystic teratoma of the ovary in a 47-year-old woman. Histologically it was composed largely of trabeculae partly of insular carcinoid and focally of individual thyroid follicles. Many cells in the carcinoid areas and even some follicular areas contained abundant argyrophile granules, and they also, in the corresponding areas, demonstrated thyroglobulin. Electron microscopic findings revealed abundant neurosecretory granules and colloid material in the same cell. We agree that this tumor is derived from hybrid showing thyroid and neuroendocrine differenciation.

PURPOSE: The purpose of this study was to identify congruence between self-perception and objective status of obesity according to %Fat, and to investigate health promotion lifestyle in college women. METHODS: The participants were a convenience sample of 392 college women who were eligible and agreed to participate in this study. Respondents were asked questions using a health promotion lifestyle profile and were evaluated for their body composition using InBody 3.0. The data were analyzed with SPSS 14.0 program, which was used for Chi square, ANOVA, and post-hoc comparison with Scheffe. RESULTS: The major findings were as follows; 1) Overall, 41.8% of participants misclassified their perceived status of weight by %Fat standards and kappa was 0.329. 2) Two percent were underweight by BMI but overweight by %Fat and 39.0% normal weight by BMI but overweight by %Fat. 3) There were significant differences in health promotion lifestyle according to self-perception of body weight but there was no difference in health promotion lifestyle according to %Fat standards. CONCLUSION: These findings suggest the necessity for development and application of tailored health promotion program based on self-perception of body weight and %Fat in order to reform incorrect body image and health behavior in college women.

Objective To discuss the value of digital tomosynthesis for detection of pulmonary nodules. Methods Thirty patients suspected of having pulmonary nodules underwent chest radiography, digital tomosynthesis and CT examination. Above image data were transferred to postprocessing work station and were reviewed by 2 radiologists with 3 years of chest-radiology diagnosis experience in a double-blind method. The number, location and size of nodules were recorded. Then, 2 radiologists reviewed the all images once more, and discuss in consensus. The sensitivities of chest radiography and digital tomosynthesis for detection of pulmonary nodules were respectively calculated according to the CT results. Chi-square test was used for radiography, digital tomosynthesis and CT examination. Results Of 30 patients, 21 were detected having pulmonary nodules by X-ray radiography and 9 were negative, the total number of 40 nodules was detected, while 89 nodules in 26 patients were detected by digital tomosynthesis, and only 4 patients were negative. CT demonstrated 102 nodules in 27 patients, and 3 patients were negative. Taking CT as "gold standard", the sensitivities of X-ray radiography and digital tomosynthesis were 27.4%(28/102)and 87.2%(89/102), X~2=4.35, P<0.05, respectively. Conclusion Digital tomosynthesis has a high sensitivity for detection of pulmonary nodules compared with X-ray radiography, and could be an excellent and necessary supplementary technique of X-ray radiography.

Pituitary stalk interruption syndrome (PSIS) is a newly discovered rare endocrinological syndrome characterized by structrual defect of pituitary and multiple deficiencies of a series of hypothalamic hormones, and thus leading to a cluster of clinical symptoms. This review will illustrate the genetic pathogenic factors influence on embryonic development, and briefly introduce the current studies of Whole-Exome Sequencing on PSIS.

PURPOSE: The objective of this study was to determine the active and environmental tobacco smoke (ETS) in biological samples (plasma, saliva and urine) among high school students in Korea. METHODS: Study samples were from 99 nonsmoker or smoking volunteers from high school in Kyungki-do in 2000. ETS was defined as the having smokers of their family members or their friends. Urinary samples were extracted with ethyl ether at pH 10.5, and the extract was injected in GC-NPD. Plasma or saliva was extracted with methylene chloride at pH 10.5 and the quantification was performed with GC-MS (SIM). Peak shapes and quantitation of nicotine and cotinine were excellent, with linear calibration curves over a wide range of 1 to 3000 ng/mL. RESULTS: The results are as followings1. The prevalence of smoking among study subjects were 18.2% among males and 6.1% among females. A 69.7% of total subjects among both males and females were exposed at ETS. 2. The primary metabolite cotinine of nicotine was good indicator of ETS exposure in nonsmokers. Salivary cotinine was found to be highly correlated to the concentration of cotinine in plasma (r=0.9480). 3. Urine cotinine was increased among those with smokers in their family members, while salivary or blood cotinine was increased among with smoking friends. 4. Blood cotinine was highly correlated with salivary cotinine, but it was relatively poorly correlated with urine cotinine. CONCLUSIONS: In conclusion, the results show how the students in high school in Korea suffer from secondhand smoke. It appeared that salivary cotinine was easy to collect and best way to predict the ETS among adolescents

The expression of two cell proliferation indices, the proliferating cell nuclear antigen( PCNA), using the monoclonal antibody in the immunoperoxidase method, and the nucleolar organizer regions (NORs), using silver nitrate staining technique, were assessed in formalin-fixed paraffin embedded material of transitional cell urinary bladder carcinomas. The aim of our study was to examine comparatively the expression of PCNA and the number of NORs in 37 transitional cell bladder carcinomas and to investigate how they correlate with tumor grade and the disease stage. It was noticed that the PCNA expression rate(%) related to grade was statistically significant only between grades II and III (p<0.05), while that between grades I and II was not statistically significant(p > 0.05). The mean number of AgNORs per nucleus between grades I and II and between grades II and III were statistically significant(p<0.05). As far as the correlation of PCNA expression rate(%) with the stage is concerned, PCNA expression rate (%) was higher in the invasive tumors(p<0.05) than in the superficial tumors and AgNOR Numbers was also greater in the invasive tumors(p <0.05). The linear correlation coefficient between PCNA expression rate (%) and AgNOR counts was 0.52(p <0.001) In conclusion, a considerable relationship was found between the histological grade and each of the two indices used. A good correlation was also demonstrated between each of PCNA expression rate(%) and AgNOR scores to the pathologic stage. Our results suggest that PCNA expressionrate( % ) and AgNOR scores may be prognostic induces in urinary bladder cancer.

The purpose of this study is to present the results of the clerkship evaluation by the students using questionnaire, to discuss the problems revealed in performing the evaluation, and to find out the ways to improve the evaluation. In 2000, the evaluation has been conducted by the Department of Radiology, Seoul National University College of Medicine. The questionnaires filled-up by 97 junior students who completed the clerkship schedule of 2 weeks were analyzed in this study. The questionnaire consisted of 28 structured items with 5-grade scale each, the contents of which included the amount and level of the overall clerkship course and those of 5 subtypes of the clerkship(self-learning, student conference, student seminar, on-site clerkship, and small group discussion with faculty). In small group discussion, enthusiasm of each faculty, delivery effect, and difficulty of the contents were also evaluated. As a result, the most items were assessed to be slightly better than average(3 or 4 point of 5 scale). It was found that the small group discussion was most favored, whereas the student seminar was least favored. Faculty activity was also scored to be better than average. There were no significant differences among all faculty activity. The limitation of this study is failure of assessing the validity and reliability of the student response. In order to improve the evaluation, we should consider following four subjects: First, all the items are carefully developed to enhance the validity and reliability of the evaluation. Second, students should be fully informed of the objects of the evaluation before it is carried out. Third, teaching support facilities for the faculty are needed. Finally, an organization which takes complete charge of the instruction evaluation must be established.
