Bronchial artery embolization is well-accepted and widely used for management of massive and recurrent hemoptysis. This may either provide a definite therapeutic measure or a stabilizing effect on the patents in preparation for surgery. Retrospectively we reviewed 129 cases(106 patients) of bronchial artery embolization with Gelfoam pudding & Ivalon for control of hemoptysis from July 1985 to january 1991. The causes of hemoptysis were pulmonary tuberculosis(80.2%). Bronchiectasis(11.3%), asperigilloma(2.8%), and others(5.7%). The cases of pulmonary tuberculosis included tuberculous bronchiectasis (40.0%), active(34.1%), undetermined(14.1%) and inactive(11.8%). @ES The results were as follows: @EN Immediate control of hemoptysis was achieved in 104 of 122 cases(85.2%). Immediate control of massive hemoptysis was achieved in 94 of 107 cases(87.6%) and of chronic intermittent hemoptysis in 10 of 15 cases(76.0%). Hemoptysis recurred in 39 of 90 follow up cases(43.3%) on follow-up studies performed ranging in period from 2 to 49 month after the initial studies. Thirty three of 81 cases of massive hemoptysis recurred(40.7%) and six of 9 cases of chronic intermittent hemoptysis recurred(67.0%). One years rebleeding rate of massive hemoptysis was 34.6%. The rebleeding cases of massive hemoptysis were controlled by conservative treatment in 25 of 33 cases(75.8%). In conclusion. Bronchial artery embolization for hemoptysis control is effective in massive hemoptysis, but nearly ineffective in chronic intermittent hemoptysis, The goal of bronchial artery embolization is lifesaving procedure without permanent effect. Especially hemoptysis related to pulmonary tuberculosis.

CT has facilitated early recognition and treatment of focal brain injuries in patients with head trauma. However. CT shows relatively low sensitivity in identifying nonhemorrhagic contusion and injuries of white matter. MR is known to be superior to CT in detection of which matter injuries, such as diffuse axonal injury. MR imaging in 14 cases of diffuse axonal injury on 2.0T was studied. The corpus callosum, especially the body portion, was the most commonly involved site. The lesions ranged from 5 to 20 mm in size with ovoid to elliptical shape. T2WI was the most sensitive pulse sequence in detecting lesions such as white matter degeneration, hemorrhagic and nonhemorrhagic contusion. The lesions were nonspecific as high and low signal intensities on T2WI and T1WI respectively. CT showed white matter abnormality in only 1 case of 14 cases. We propose MR imaging as the primary imaging procedure for the detection of diffuse axonal injury because of its multiplanar capabilities and higher sensitivity.

Callus is a nonpenetrating circumscribed hyperkeratosis produced by repeated friction or pressure. It occurs on parts subjected to intermittent pressure, particularly on the palms and soles, and particularly over the bony prominences of the joints. In painful callosities of the feet, ill-fitting shoes and orthopedic problems of the foot (bunions, exostoses) are some of the etiological factors to be considered. Gout is a condition of inborn metabolic and/or acquired form of the disease characterized by hyperuricemia, tophaceous deposits of sodium urate and recurrent attacks of arthritis. We present a case of callus caused by tophi. The patient was a 45-year-old man who had complained of a painful, well-demarcated, hyperkeratotic plaque on the heel of the left foot for 18 months. After the tophi beneath overlying whitish thickened skin had been removed, the skin lesion disappeared and to date has not recurred.

BACKGROUND: During the adolescent growths spurt, iron deficiency becomes more common, particularly with the additional factors of menstrual blood loss in females and the androgen-related rise in hemoglobin concentration in males. This study was conducted to investigate the iron status in the adolescent students. METHODS: Venous peripheral blood was sampled from 178 males(79 of 12-13years, 99 of 15-16years) who were 1st grade students of two boy's middle schools and two high schools and from 186 females(87 of 12-13years, 99 of 15-16years) who were 1st grade students of two girl's middle schools and two high schools. Laboratory procedures included a hemoglobin, hematocrit, serum iron, TIBC and serum ferritin. Transferrln saturation was calculated. RESULTS: 1) Mean values were hemoglobin 13.7+/-0.78 g/dl, hematocrit 40.6+/-2.47%, serum iron 127.6+/-43.02 ug/dl, TIBC 387.9+/-47.73 ug/dl, transferrin saturation 33.3+/-11.38%, and serum ferritin 26.1+/-16.90 ng/ml in 12-13years old males. 2) Mean values were hemoglobin 13.7+/-0.85 g/dl, hematocrit 40.9+/-3.79%, serum iron 99.4+/-34.93 ug/dl, TIBC 387.8+/-45.53 ug/dl, transferrin saturation 26.2+/-9.99%, and serum ferritin in 22.7+/-14.18 ng/ml in 12-13years old females. 3) Mean values were hemoglobin 15.2+/-0.84 g/dl, hematocrit 45.9+/-2.77%, serum iron 144.9+/-51.97 ug/dl, TIBC 419.8+/-52.46 ug/dl, transferrin saturation 34.2+/-10.44%, and serum ferritin 31.2+/-20.91 ng/dl in 15-16years old males. 4) Mean values were hemoglobin 13.2+/-0.89 g/dl, hematocrit 39.9+/-2.78%, serum iron 111.1+/-39.78 ug/dl, TIBC 392.8+/-50.06 ug/dl, transferrin saturation 28.9+/-10.85%, and serum ferritin 21.4+/-17.11 ng/ml in 15-16years old females. 5) The prevalence of iron deficiency was 8.9% and 10.1% in 12-13years and 15-16years old males respectively. In 12-13years and 15-16years old females, the prevalence was 16.1% and 29.3% respectively. The prevalence of iron deficincy anemia was 1.1% and 2.0% in 12-13years and 15-16years old female and absent in male. CONCLUSIONS: Although hemoglobin is normal, we recommend to check other parameters to optimize the identification of individuals with iron deficiency.

BACKGROUND: Methicillin-resistant Staphylococcus aureus is a major etiologic agent of hospital acquired infection. Coagulase negative staphylococci (CNS) species are previously regarded as contaminants. However nowadays CNS were regarded as an important cause of bacteremia. So in this study we wanted to analyze the patterns of plasmids and antimicrobial susceptibility test of Staphylococcus species isolated from clinical specimens. METHOD: Plasmid DNA was extracted and then processed through restriction enzyme digestion for plasmid analysis of S. aureus and antimicrobial susceptibility, which was done by agar dilution method. For S. epidermidis plasmid analysis was done without enzyme digestion. RESULTS: All of MRSA have 1 to 5 plasmids. There exists 6 patterns of S. aureus plasmid without enzyme digestion. With EcoRI and HindIII digestion pattern were more distinct and clear. For S. epidermidis enzyme digestion is not needed. Antimicrobial susceptibility patterns of S. aureus are simple whereas S. epidermidis showed variable patterns. CONCLUSIONS: For the plasmid analysis of S. aureus restriction enzyme digestion is required and for the S. epidermidis, the pattern of plasmids are variable so without restriction enzyme analysis we can obtain several patterns. Plasmid analysis will be used as a good epidemilogical tool for Staphylococcus.

Phosphoinositide-specific phospholipase C(PLC) is known as a key enzyme which produces two major second messengers: diacylglycerol and inositol 1,4,5 trisphosphate. Although it has been suggested that PLC beta isozymes have important roles in nervous system, less is known about the function of PLC beta in development of nervous system. We have localized the mRNA expressions of PLC beta isozymes in the postnatal rat brains by id firm hybridization histochemistry. In the postnatal rat brains, each isozyme of PLC beta showed differential expression pattern. The expression of PLC beta1 mRNA was found in various areas including olfactory bulb, cerebral cortex, caudate putamen, hippocampus, dentate gyrus, and cerebellum. In general, the expression in these areas was gradually increased after birth (PO) until postnatal day 21 (P2l) and slightly decreased to adult level. The expression of PLC beta2 mRNA was not found in postnatal rat brains. The expression of PLC beta3 mRNA was found from P0, peaked at Pl4, and decreased to adult level in the purkinje cells of cerebellum. PLC beta4 mRNA was strongly expressed in the thalamus, cerebellum, cerebral cortex, and olfactory bulb. In these areas, the expression was gradually increased after birth, peaked at P2l, and decreased to adult level. In whole body parasagittal sections of 18 day old rat embryo, PLC betal mRNA was exclusively expressed in nervous tissue, PLC beta3 and PLC beta4 were expressed in various tissues, and the expression of PLC beta2 was not found in any kind of rat tissues. From the different spatiotemporal mRNA expression patterns of PLC beta isozymes in the postnatal rat brains, it is suspected that each PLC beta isozyme may have specific role in signal transduction for postnatal development of rat brain.

Epstein-Barr virus(EBV) is associated with a wide spectrum of benign and malignant disorders including leukoplakia, Hodgkin's lymphoma, central nervous system lymphoma, peripheral T cell lymphoma and nasopharyngeal undifferentiated carcinoma. There are several distinctive aspects of biology of the virus that are important in investigation of virus in clinical specimens. The abundant expression of the EBER mRNA transcripts makes possible the sensitive detection of latent expression in EBV-associated tumors. Although there has been a dramatic increased interest in the direct characterization of EBV in clinical specimens, there have been few studies about the effective and reliable positive controls in performing in situ hybridization technique for EBV, especially on paraffin-embedded tissue. We applied Burkitts lymphoma cell line as positive control in EBV in hydridization using Oncor Kit. The cell block of Burkitt lymphoma cell line(CCL85 EB-3) showed strong and specific positivity for EBER in situ in nuclei of EBV infected cells.

Uterine sarcomas are relatively rare tumors of mesodermal origin that constitute 2-6% of uterine malignancies. Uterine sarcomas include endometrial stromal sarcoma (ESS), leiomyosarcoma (LMS), malignant mixed m llerian tumor (MMMT) of both homologous and heterologous type, pure heterologous sarcomas, blood vessel sarcomas, and lymphoma. Endometrial stromal tumors are divided into three types: 1) endometrial stromal nodule, 2) low-grade stromal sarcoma or endolymphatic stromal myosis, and 3) endometrial stromal sarcoma. The low grade endometrial stromal sarcoma is very rare. It shows occasional local recurrence, which might arise from endometrial stroma, from adenomyosis, and rarely from endometriosis. We have experienced a case of low grade endometrial stromal sarcoma of the uterus in a 54-year-old woman, which is presented with a review of literatures.

In an attempt to investigate which of the ST-segment parameters, e.g., ST-segment level, ST-segment slope, ST-segment index and ST-segment intergral obtained by mannual drawing can most sensitively indicate quantitatively the extent of exertional myocardial ischemia in patients with angina pectoris, 26 patients with angina pectoris underwent exrecise stress testing, using a bicycle ergometer and thallium-201 myocardial perfusion scintigraphy(Thallium-201 MPS). The exrecise was terminated either when symptoms or signs indicative of myocardial ischemia developed or when the heart rate reached the predicted maximal heart rate during exrecise. The myocardial ischemia region was quantitated by Thallium-201 MPS. The number of myocardial ischemia segments was similar in patients who had positive exrecise test(4.9+/-1.9) and in those who had negative result(3.7+/-2.2). However, it was greater in patients who showed pseudonormalization of the T wave in exercise ECG(6.3+/-2.6) than in those with negative exercise test(3.7+/-2.2)(P<0.05). The extent of myocardial ischemia region expressed by the number of myocardial ischemia segments correlates best with the ST-segment index(r=-0.83) among ST-segment slop(r=-0.60), ST-segment intergral(r=-0.59) and ST-segment(r=0.50). These data suggest that the ST-segment index is the most reliable indicator to reveal the extent of exertional myocardial ischemia among the ST-segment parameters and that pseudonormalization of T wave in exercise ECG is a finding indicative of exertional myocaridial ischemia in patients with angina pectoris.
