Breathing gas carries important physiological information. Technology for detection of breathing gas has become a research focus because of the advantages of nondestructive sampling and convenient operation. Proton transfer reaction mass spectrometry (PTR-MS) plays an irreplaceable role because of the advantages of high sensitivity, fast response and good specificity. In this paper, the principle of PTR-MS is introduced first, followed by research progress of PTR-MS in the field of breathing gas detection. Factors influencing the test results are analyzed. Finally, future prospects of development for PTR-MS in the field of breathing gas detection are discussed.

A case of invasive cribriform carcinoma of the breast is presented with fine need- le aspiration cytologic features. The aspiration was performed from a papable 2.0cm mass in the upper outer quadrant of the right breast in a 53 year-old woman. The aspirate showed cellular smear composed of larger three dimensional tight clusters, smaller monolayered loose clusters, and many individual cells on the clean background. In the clusters, the tumor cells were bordering central lumina, quite similar to the cribriform in histology. The tumor cells in the clusters and individual tumor cells had uniform, small and round nuclei. The chromatin was finely granular, and nuclear membrane was smooth. No discernible nucleoli were present (nuclear grade 1-2). Unless the abundance of individual cells and the cribriform growth pattern are recognized in the smear, the cytologic diagnosis of invasive cribriform carcinoma is difficult.

BACKGROUND: This study used MDS-HC 2.0 (Minimum Data Set-Home Care) to analyze the health and the state of function of the traveling health objects. This study was intended to make use of it with the basic materials for providing them with traveling health service suited for the requirement on the health of the traveling health objects. METHODS: The subjects of this study were 1160 people (over 65 years) living under management control of local Health Center from September 7th to October 3th, 2006. This study was analyzed with inter RAI program & SPSS/WIN 10.0, chi-square -test, t-test, and ANOVA. RESULTS: The result showed that 8.97 CAPs per an elderly person was identified and the subjects over 60% had an injury problem from a fall, health prevention service, vision, IADL, pain, and cognition. The number of CAPs in general was high in higher age and the less educated, and those without a job. But, in subjects that had a life partner and a spouse, the number of CAPs was low. In CAPs by the distinction of sex, CAPs which was much more in man than women in statistics were the improvement of health, the abuse of alcohol and drinking wine, bedsore, and the weak supply system. CAPs which women had much more were the function of the heart and the lungs, pain, the performance of the doctor's advice, health prevention service, and incontinence of urine and insertion of catheter. According to the results comparing CAPs by the level of the ADL, the number of CAPs was shown that the group of ADL 2 was higher than group ADL 1. The matter in which the traveling health service had to be applied in all both ADL1 and ADL2 was injury from a fall, health prevention service, and vision. Conculsion: MDS-HC is applicable to decide the care needs for health and social service supplies. The results can be further applicable for careplan, and referral criteria in continuum of care service over long-term care spectrums.

BACKGROUND: This study aimed to empirically investigate the determinants on oxygen free radical degree which causes biological damage focusing on smoking habit and health behaviors in daily life. METHODS: In this cross-sectional study, the subjects were adult males who submitted free radical tests among the examinees of the comprehensive medical testings at an university hospital in Suwon from 2008 to 2010. Total 497 samples were used in analyses for clarifying the relations of free radical degree to age, smoking, obesity, and other health behaviors. RESULTS: First, the degree of oxygen free radical increases by 0.164 as the age group increases (P<0.05). Second, the degree of oxygen free radical increases by 0.547 as the smoking habit increases (P<0.001). Third, the degree of oxygen free radical increases by 0.087 as the exposure to hazardous factors in workplace increases (P<0.001). CONCLUSIONS: The findings of the study imply that the smoking habit has more great influence on the increase of oxygen free radical in body than any other health behaviors. The causality of free radical to smoking and health behavior was not identified due to the limit of the cross-sectional study so it needs to be studied prospectively in the future.

Endodermal sinus tumor of the mediastinum is a very rare malignant tumor, usually affecting young adolescents, and its histologic findings are characteristic as that of gonadal germ cell origin. We describe the cytologic finding of fine needle aspiration of mediastinal endodermal sinus tumor in a 19-year-old male patient, comparing with tissue section. The tumor cells in smears were usually in tight clusters with large overlapping cells, which were arranged in a papillary or microacinar pattern, suggesting carcinoma. The tumor cells were large, round or oval with a small amount of cytoplasm which was occasionally vacuolated and had indistinct border. The nuclei were large, pleomorphic, and vesicular with large promi- nent nucleoli. The tissue sections showed typical findings of endodermal sinus tumor. Careful correlation of cytological findings and the serum alpha-fetoprotein level would be helpful to confirm the diagnosis.

PURPOSE: The purpose of this study was to investigate factors that influence married female immigrants' perceived health status. METHODS: This study was a retrospective review of dataset from the 2012 National Multicultural Family Survey in Korea. Data were analyzed using descriptive statistics, t-tests, an analysis of variance (ANOVA), Pearson correlation analysis, and multiple regression with the data of 3,014 married female immigrants. RESULTS: Multiple regression analysis showed that demographic factors (age, education level, nationality, period of residency in Korea, and residential area), socio-economical factors (monthly family income, employment, support from the government for basic living, and Medicaid), social support factors (marital conflict, satisfaction with family relationships, some one to talk about self or family matters, meeting with homeland friend, and participation in community meeting), and immigration factors (life satisfaction, experience of social discrimination, and difficulties with living and using medical care) were associated with perceived health status. CONCLUSION: It is important to pay closer attention to immigrant women who have low economic status, less social support, experience difficulties with living in Korea and using medical care. An effective support system for this population should be developed in order to help them successfully transition.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having pre- dominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei, The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchioloalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.

Objective To evaluate myocardial apoptosis with 99Tcm-C2A-GST myocardial imaging using the recombined C2A domain of Synaptotagmin Ⅰ by gene engineering. Methods ( 1 ) The C2A gene was inserted into the prokaryotic glutathione S-transferate (GST) fusion protein expression plasmid pGEX-6P-1. The recombinant plasmid was transformed into E. coli BL21. C2A-GST fusion protein was purified after BL21 was induced with isopropyl-β-D-1-thiogalactopyranoside (IPTG). (2)The activity of fusion protein was identified by cell binding test with fluorescein-5-isothiocyanate (FITC)-C2A-GST. (3) The C2A-GST fusion protein was labeled with 99Tcm using 2-iminothiophene hydrocoride method. Radiochemical purity was determined with thin layer chromatography. (4)99Tcm-C2A-GST (7.4 MBq) was injected to ischemia-reperfusion rat models through tail vein. The image was acquired with SPECT at 1 h after injection, and then hearts were removed, rinsed with saline and dyed with triphenyl tetrazolium coride (TTC). The ischemic myocardium was separated from the viable myocardium and was weighted. Its radioactivity was measured by gamma counting. The difference of uptake of radiotracer between ischemic myocardium and normal myocardium was compared using percentage activity of injected dose per gram of tissue ( % ID/g) with standard deviation. SPSS 12.0 and t-test were used for data analysis. Results ( 1 ) C2A-GST fusion protein wassuccessfully expressed and its relative molecular weight was 3.8 × 104. (2) FITC-C2A-GST binding to apoptotic cells could be observed by fluorescent microscopy. (3) The radiochemical purity of 99Tcm-C2A-GST was (98.90 ±0.43)%. (4)The imaging studies showed that there was focal uptake of radioactivity in the ischemic myocardium. In vitro uptake of 99Tcm-C2A-GST was (2.41 ±0.32) % ID/g by the ischemic myocardium, however 99Tcm-C2A-GST-N-hydroxysuccinimide (C2A-GST-NHS) was (0. 82 ± 0. 24) % ID/g. There was statistically significant difference between those two groups (t = 10. 6, P ＜0.01 ). Conclusion The C2A domain of Synaptotagmin Ⅰ expressed by gene engineering can be used as the tracer for noninvasive detection of ischemic myocardium in the ischemia-reperfusion rat model.
