Electrocardiograms were observed in 168 patients with typhoid fever and were analyzed according to the duration of illness and hemoglobin level. The following results were obtained. 1) 124 patients out of 168 patients showed abnormal electrocardiographic findings. 2) The most prevalent abnormal findings were observed during third to fourth week of illness. 3) The lower the hemoglobin level, the higher frequency of electrocardiographic abnormalities were found. 4) Among the electrocardiographic disorders, sinus tachycardia was the most common finding and it was found in 60 cases(35.7%). The major abnormalities were ST-T change, low QRS voltage, prolongation of Q-T interval and prolongation of P-R interval: the over all incidence of these were 26.8%, 15.5%, 13.7% and 9.55 respectively. In addition to the major abnormalities, incomplete right bundle branch block (5.4%), premature ventricular contractions(3.0%) and abnormal Q wave(1.2%) were observed.

PURPOSE: Transglutaminase 4 (TGase 4) belongs to a family of enzymes that catalyzes the post-translational modification of proteins. In an attempt to establish its physiological function(s), the distribution of TGase 4 expression in the human eye was determined. METHODS: Ocular tissues obtained from five human whole eyeball postmortem (40(+1) weeks at gestation age, 2 months, 48, 66, 76 years) were stained with monoclonal antibodies against human TGase 4 using indirect immunohistochemical method. RESULTS: TGase 4 was found in the lacrimal glands, corneal epithelium and endothelium, conjunctival epithelium, lens epithelium, retina (inner segment of photoreceptor, external limiting membrane, outer plexiform layer, inner plexiform layer, retinal nerve fiber layer and internal limiting membrane), iris, ciliary muscle, ciliary nonpigmented epithelium and trabecular meshwork. Endothelium of blood vessels in all ocular tissues was also stained. Conjunctival stroma, choroid, anterior tenon's capsule were faintly stained. No evidence of immunostaining for TGase 4 was found in the corneal stroma, iris stroma, lens nucleus, ciliary process, sclera, extraocular muscle and optic nerve. CONCLUSIONS: The expression pattern of TGase 4 was different from those of other TGase isoforms in the human eye. This result may be helpful in further investigation of the role of TGase 4 in the ocular tissue.

Moyamoya disease is characterized by bilateral stenosis or occlusion of distal internal carotid artery (ICA) bifurcation including its proximal branches and abnormal vascular network (moyamoya vessel, MMV) in the vicinity of the arterial occlusions. It is the most common pediatric cerebrovascular disease in Eastern Asia, particularly in Korea and Japan. The etiology is still unknown, but much about the pathology from autopsies, factors involved in its pathogenesis, and its genetics have been studied and reported. It may cause ischemic attacks or cerebral infarctions in children and cerebral hemorrhage in adults. Because of its aggressive clinical course in very young children, the need for early detection and treatment has been recognized. Magnetic resonance imaging (MRI)/MR angiography (MRA), cerebral hemodynamic studies, and cerebral angiography are used for the diagnosis. The treatment basically focuses on prevention of further ischemia and infarction through revascularization. Technically, direct and indirect bypass methods are used. The treatment strategy needs to be individualized in each patient. Outcomes of revascularization procedures are excellent in preventing transient ischemic attacks (TIAs) in most patients.

OBJECTIVE: Surfactant protein (SP)-A and SP-D are involved in host defense mechanism. The author was prompted to perform a study on morphologic change and SP-A, SP-D level of surfactant after pulmonary injury inflicted by intratracheal bleomycin injection. METHODS: Fifteen white adult rats each weighing 250 g (Sprague-Daw ley) were divided into study (receiving bleomycin, n=9) and control groups (n=6). Study group were given a intratracheal injection of belomycin (5 mg/kg). Two groups were grown for five weeks at twenty five degrees Celsius, after which lung tissue were examined for morphologic change and SP-A and SP-D levels were measured using Western blot assay with densitometer. RESULTS: Before the study, the average weight of the study group was 286.69+/-14.54 g, and control was 286.69+/-14.54 g. Five weeks later, the average weight of the study group was 347.31.31+/-60.53 g and control group 352.71+/-16.84 g. However, no statistical significance was noted. On light microscopy, the control group exhibited normal findings while widening of lung interstitium and fibrotic change coupled with more prominent inflammatory cell infiltration were noted in the study group. The SP-A level were 15.34+/-1.52 ODU/microgram in the study group and 7.70+/-2.81 ODU/microgram in the control. SP-D level were 3.53+/-1.46 ODU/microgram and 7.51+/-2.33 ODU/microgram in the study and control groups respectively, there was a statistical significance (p<0.05). CONCLUSION: The morphologic change after pulmonary fibrosis induced by intratracheal bleomycin injection in white rats can be summarized as chronic inflammatory cell infiltration, fibroblast proliferation, deposition of collagen tissues, and lowering of SP-D level were noted. The increase of SP-A level is subject to further study in the future.

OBJECTIVE: The aim of this study was to investigate the prevalence of spinal deformities such as scoliosis, thoracic kyphosis and lumbar lordosis in Korean elementary school students. METHOD: Five hundred forty Korean elementary school students were preliminary screened for spinal deformities by physical examinations and the three dimensional skeletal analysis system. The study time and pain regions were investigated in sitting on chairs that commonly used in Korean elementary school. RESULTS: The prevalence of scoliosis, thoracic kyphosis and lumbar lordosis were 9.8%, 18.7% and 23.1%. There was a significant difference in study time between spinal deformity group and control group (p<0.01). In spinal deformity group, pain regions were low back (45%), posterior neck (23%), buttock (21%) and shoulder and elbow joints (11%). CONCLUSION: The spinal deformities showed high prevalence in elementary school students assessed by the three dimensional skeletal system analyser. The long term follow-up evaluation and confirmative radiographic study will be necessary to assess curve progression in spinal deformity group.

The objective of this study is to differentiate the mild dementia of Alzheimer type from the questionable dementia and non-demented elderly using the neurocognitive assessment. Subjects of 28 women who were registered to kwangju Community Mental Health Center were as follows: 14 non-demented, 9 questionable dementia, 5 mild dementia of Alzheimer type. The diagnosis were made using DSM-IV, Clinical Dementia Rating Scale. The neurocognitive functions were assessed with following test tools 1) attention: Digit span, Visual span, Continuous attention; 2) memory: Logical memroy, Verbal paired associates-easy/hard 3) visual perception and visuospatial ability: Visual recognition test, Construction; and 4) language: Comprehension and Aphasia severity rating scale; 5) higher cortical function: Hypothesis formation, Perseveration, Similarity, Judgment, and Go-No-Go test. Group differences were analyzed with one way ANOVA test in SPSS 8.0 for win and LSD method as post-hoc analysis. The questionable dementia group showed significant difference in Verbal paired associateseasy pair, Construction, Aphasia severity rating scale and Similarity from the non-demented normal control group but showed no difference from the mildly demented group. These results suggest that the questionable dementia is actually very early or very mild stage of dementia of the Alzheimer type.

BACKGROUND: There are evidences that uPA and its inhibitor play a key role in tumor spread. We studied whether uPA and PAI-1 expressions could serve as prognostic parameters along with clinical, gross and microscopic findings in gallbladder carcinomas. METHODS: We analyzed 42 cases of gallbladder carcinomas by immunohistochemical staining and clinicopathologic parameters. RESULTS: uPA and PAI-1 were more frequently expressed in the adenocarcinoma than in the normal or benign gallbladder tissue. The uPA expression in the glands of low grade adenocarcinoma was significantly correlated with both distant and lymph node metastases. The uPA expression in the stroma around the low grade adenocarcinoma was significantly correlated with either distant or lymph node metastasis. The PAI-1 expression was significantly correlated with lymph node metastasis only for both distant and lymph node metastases. In multivariate analysis, the lymphatic invasion was significantly related to poor survival (p= 0.0115). In univariate analysis, the cases without lymphatic invasion had prolonged survival. Positive expression of uPA in the glands of low-grade adenocarcinoma was significantly correlated with poor survival (p=0.0391). CONCLUSION: In conjunction with clinicopathologic findings, expressions of uPA and PAI-1 may be useful prognostic markers in gallbladder carcinomas.

Purpose: To evaluate the effect of the intense pulsed light (IPL) and meibomian gland (MG) expression (MGX) combination therapy according to the total numbers of sessions in the meibomian gland dysfunction (MGD). Methods: Ninety patients with MGD were included. Patients had maximal five sessions of IPL (Aqua Cel, Jeisys Medical) and MGX combination therapy at 2-week intervals. The ocular surface disease index (OSDI) questionnaire score, MG profile grades, tear matrix metalloproteinase-9 (MMP-9), tear break-up time (BUT), tear osmolarity, tear secretion, and corneal erosions were evaluated. Results: The number of patients who had a total of one to five sessions (1S to 5S) was 10, 25, 17, 20, and 18, respectively. The time-serial decrease of OSDI scores was significant in patients who had three or more sessions (3S, p = 0.002; 4S, p < 0.001; 5S, p < 0.001). The MG expressibility grade decreased with two or more sessions (2S–5S, p < 0.001), but the meibum quality significantly improved with all sessions (1S, p = 0.012; 2S, p = 0.024; 3S, p = 0.015; 4S, p < 0.001; 5S, p < 0.001). Although tear BUT increased even in patients with one session (1S, p = 0.040; 3S, p = 0.005; 4S, p = 0.006; 5S, p = 0.021), tear MMP-9, osmolarity, Schirmer I, and corneal erosions were not improved in every number of sessions. The female sex was the sole contributor to the final symptomatic improvement (p = 0.042), and the MGD stages were not related to the final OSDI decrease. Conclusions The OSDI score, MGD grades, and BUT were improved after the IPL and MGX combination therapy in MGD patients. Unlike MGD grades and tear film instability might be improved just after a few sessions, the overall subjective relief was accomplished in three or more sessions.

The majority of clinical studies on moyamoya disease (MMD) have focused on anterior circulation. The disease involvement of posterior circulation in MMD, mainly in the posterior cerebral artery (PCA), has been mentioned since the early 1980s, and it has been repeatedly emphasized as one of the most important factors related to poor prognosis in MMD. However, its clinical features and outcome have only been elucidated during the last few years. In this review, the angiographic definition of PCA stenosis is summarized. The clinical features are elucidated as being either early-onset or delayed-onset, according to the time of PCA stenosis diagnosis in reference to the anterior circulation revascularization surgeries. The surgical strategy and hypothesis on the mechanism of PCA stenosis is also briefly mentioned. It appears that some MMD patients may show PCA stenosis during the early or late course of the disease and that the presenting symptoms may vary. Because the hemodynamic compromise caused by PCA stenosis may respond well to surgical treatment, clinicians should be aware of the condition, especially during follow-up of MMD patients.

PURPOSE: This study was designed to compare the amount of polymerization shrinkage of dual-cure resin cements according to different polymerization modes and to determine the effect of light activation on the degree of polymerization. MATERIALS AND METHODS: Four kinds of dual-cure resin cements were investigated: Smartcem 2, Panavia F 2.0, Clearfil SA Luting and Zirconite. Each material was tested in three different polymerization modes: self-polymerization only, immediate light polymerization and 5 minutes-delayed light polymerization. The time-dependent polymerization shrinkage-strain was evaluated for 30 minutes by Bonded-disk method at 37degrees C. Five recordings of each material with three different modes were taken. Data were analyzed using one-way ANOVA and multiple comparison Scheffe'test (alpha=.05). RESULTS: All materials, except Panavia F 2.0, exhibited the highest polymerization shrinkage-strain through delayed light-activated polymerization. No significant difference between light activation modes was found with Panavia F 2.0. All materials exhibited more than 90% of polymerization rate in the immediate or delayed light activated group within 10 minutes. CONCLUSION: As a clinical implication of this study, the application of delayed light activation mode to dual-cure resin cements is advantageous in terms of degree of polymerization.
