PURPOSE: The purpose of this study was to explore the effects of abdominal breathing on relieving anxiety in women diagnosed with preterm labor. METHOD: This was a pilot study, which was based on a repeated pre-post experiment design without a control group. Seven patients with preterm labor who were admitted to Y university medical center, Seoul, Korea, participated in the experiment. They were under receiving ritodrine hydrochloride(Yutopa) as tocolytic therapy and did not have any other complications. The patients were taught abdominal breathing, which is a modified version of Mason's breathing technique. The experimental treatments were done 33 times from February 18 to June 19 in 2005. RESULT: After abdominal breathing, the average psychological anxiety level decreased significantly. The physical anxiety levels of preterm labor patients were measured by blood pressure, pulse, and skin temperature. After abdominal breathing, the average systolic and diastolic blood pressure decreased from 117.3mmHg to 107.6 mmHg (z=-3.85, p<.001) and from 67.3mmHg to 62.7 mmHg (z=-3.14, p<.005), respectively. The average pulse rate also decreased from 97.2/min to 89.8/mim (z=-4.76, p<.001). The average skin temperature increased from 94.0 to 94.9(z=-4.80. p<.001). CONCLUSION: Abdominal breathing is effective for relieving anxiety of women diagnosed with preterm labor. This study, however, has been limited to short-term effects, and therefore further studies are required in order to examine the long-term effects of abdominal breathing.

PURPOSE: To evaluate the expression of senescence-related proteins according to the aging process and to determine the role of senescence-related proteins in the bone tissue and their effects on the process of bone union. MATERIALS AND METHODS: 18 Sprague-Dawley rats (8 weeks old: 7, 32 weeks old: 6, and 70 weeks old: 5) were used in the experiment. A unilateral closed femur fracture was made, and the fracture callus was obtained 2 weeks after the fracture. The ossification process was observed in proliferative chondrocytes, the hypertrophic chondrocytes, and in the mesenchymal layer individually by immunohistochemistry, using p16, p21, c-fos and c-jun antibodies. RESULTS: There was no significant differences in the manifestation of p-16, p-21, c-fos, c-jun gene according to the age. The positive ratio of p-16 was maximal in proliferative chondrocytes (54.93%) and decreased in the mesenchymal layer (46.48%), and in hypertrophic chondrocytes (10.85%), in order. The positive ratio of c-fos was maximal in proliferative chondrocytes (73.32%) and decreased in the mesenchymal layer (51.84%), and in hypertrophic chondrocytes (9.64%), in order. CONCLUSION: We believe that senescent genes in the bone tissue participate in the differentiation of osteochondral cells and in the process of fracture callus ossification.

Up to 1937, 357 cases of tongue tuberculosis had been reported. However, Since potent antituberculosis drugs had been introduced, the incidence of oral tuberculosis lesions has been dramatically decreased. This might be related to the marked vascularity of the tongue which enables a high concentration of the drug to be reached to the lesion. Both the primary and secondary types of tuberculosis can be revealed in the oral cavity. In the primary type, the causative organisms are directly inoculated in the oral mucosa of a person who has never been tuberculosis earlier and who has not acquired an immunity to the disease, In the secondary type, tuberculosis of the oral cavity is coexistent with pulmonary disease. We report a case of tongue tuberculosis with pulmonary tuberculosis, with a review of literature.

We evaluated the results of sequential SPECT dual-isotope imaging with Tl-201 and Tc-99m MIBI in 24 patients, all of whom also had coronary angiography within the past one month. Coronary angiography showed that 12 patients had no CAD, 4 patients had one-vessel CAD, 7 patients had two-vessel CAD and 1 patient had three-vessel CAD. Serial studies of resting Tl-201 and dipyridamole stress Tc-99m MIBI were completed within 2 hours. When more then 50% of coronary artery narrowing was considered significant. The overall sensitivity and specification of CAD detection were 91.7%. The sensitivity of CAD detection in patients with one-vessel and multi-vessel diseases was 75% and 100%, respectively. Therefore, sequential dual-isotope SPECT demonstrated high sensitivity and specificity of CAD detection. In conclusion, sequential dual-isotope imaging is feasible and can be completed in a short time and may therefore enhance laboratory throughput and patient convenience.

PURPOSE: There has been many reports for the effect of attenuation correction on myocardial perfusion SPECT. We studied the effect of attenuation correction with CT (computed tomography) in patients with normal coronary angiography. MATERIALS AND METHODS: Fifteen patients with normal coronary artery on angiography and low likelihood of coronary artery disease were enrolled in this study (male: 6, female: 9, mean age: 58+/-8 year). Myocardial perfusion SPECT was done with Millennium VG with Hawkeye device (GE, SPECT/CT camera). A visual analysis and polar map quantification (Emory tool box) was performed. In quantitative analysis, percent uptake of each myocardial wall on polar map (percent of maximal uptake) was compared between non-corrected (NC) and corrected (AC) images. RESULTS: Visual analysis showed AC images led to an increase of uptake in the inferior wall, but decrease of uptake in the anterior wall, apex and septum. Liver activity is also increased in AC images. In quantitative analysis, the percent uptake is decreased in the anterior wall, apex and septum, but increased in the inferior wall. It is helpful to interpret the images in the inferior wall after AC, but difficult in the apex and anterior wall after AC. CONCLUSION: AC is helpful in the inferior wall. But in the apex or anterior wall, AC must be carefully applied to normal perfused myocardium.

Main bronchial reconstruction is anatomically suitable for benign main bronchial stenosis. But, it has been hardly recommended for operative mortality and morbidity. This study was aimed at providing validity and the proper clinical information of bronchoplasty for benign main bronchial stenosis by reviewing the results we obtained over the last ten years for main bronchial reconstruction operations. We retrospectively reviewed admission and office records. Twenty eight consecutive patients who underwent main bronchoplasty were included. Enrolled patients underwent main bronchial reconstruction for benign disease (tuberculosis in 21, trauma in 4, endobronchial mass in 3). Concomitant procedures with main stem bronchoplasty were performed in 19 patients. There were no incidences of postoperative mortality and significant morbidity. There were 2 cases of retained secretions, and these problems were resolved by bronchoscopy or intubation. All of the patients are still alive without obstructive airway problem. Bronchoplasty should be considered as one of the primary treatment modalities, if it is anatomically feasible.

PURPOSE: N-13 ammonia uptake and retention in the myocardium is related to perfusion and metabolism. There are several potential advantages of N-13 ammonia positron emission tomography (PET) to detect myocardial ischemia, such as higher spatial resolution, greater counting efficiencies, and robust attenuation correction. But there are few reports comparing Tc-99m myocardial perfusion single photon emission tomography (MPS) and N-13 ammonia PET. We thus compared adenosine stress N-13 ammonia PET/CT and Tc-99m sestamibi MPS in patients with suspected coronary artery stenosis. MATERIALS AND METHODS: Seventeen patients (male 13 : 63+/-11 years old) underwent adenosine stress N-13 ammonia PET/CT (Discovery ST, GE), Tc-99m sestamibi MPS (dual head gamma camera, Hawkeye, GE) and coronary angiography within 1 week. N-13 ammonia PET/CT and Tc-99m sestamibi MPS images were assessed with a 20-segment model by visual interpretation and quantitative analysis using automatic quantitative software (Myovation, GE). RESULTS: Both sensitivities and specificities of detecting an individual coronary artery stenosis were higher for N-13 ammonia PET/CT than Tc-99m sestamibi MPS (PET/CT: 91%/ 89% vs MPS: 65%/ 82%). N-13 ammonia PET/CT showed reversibility in 52% of segments that were considered non-reversibile by Tc-99m sestamibi MPS. In the 110 myocardial segments supplied by the stenotic coronary artery, N-13 ammonia PET/CT showed higher count densities than Tc-99m MPS on rest study (p<0.01), and the difference of count density between the stress and the rest studies was also larger on N-13 ammonia PET/CT. CONCLUSION: Adenosine stress N-13 ammonia PET/CT had higher diagnostic sensitivity and specificity, more reversibility of perfusion defects and greater stress/rest uptake differences than Tc-99m sestamibi MPS. Accordingly, N-13 ammonia PET/CT might offer better assessment of myocardial ischemia and viability.

Prolymphocytic leukemia is a chronic lymphoproliferative disorder, characterized by prominent splenomegaly, prolymphocytes accounting for more than 55% of circulating lymphocytes, no significant peripheral lymphadenopathy and short term survival with terminal fatal multi-organ failure. We report a case of B-cell prolymphocytic leukemia in a 57-year-old woman who presented with easy bruising and arthritis for 1 year and low abdominal pain for 2 months. Physical examination revealed gingival hypertrophy and mild splenomegaly. On peripheral blood smears the leukocytes were markedly increased in number due to leukemic cells that count about 62% of leukocytes. The bone marrow aspiration smear and biopsy revealed diffuse infiltration of medium to large prolymphocytes having moderate amount of basophilic cytoplasm, round to oval nuclei with coarse chromatin, and prominent nucleoli. Abdominal pain aggravated despite chemotherapy, and pelvic computed tomography (CT) revealed a huge lobular pelvic mass which had increased in size on the follow-up CT. Total hysterectomy with bilateral adnexectomy was performed. Microscopic findings included massive infiltration of prolymphocytic cells in the uterus, upper vaginal wall, bilateral ovaries, and bilateral mesosalpinges. On immunohistochemistry, the leukemic cells showed B cell gamma light chain phenotype.
