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.

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.

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.

Purpose: This study evaluated the objective changes in the contralateral eye after unilateral cataract surgery. Methods: The study was designed as retrospective observational study. It included 44 patients who underwent unilateral cataract surgery. Collected data were uncorrected and corrected visual acuity, spherical equivalent, intraocular pressure, contrast sensitivity (CS), stereoacuity, and anterior segment optical coherence tomography parameters. Data were collected preoperatively, and 1 week and 1 month postoperatively for each eye. Results: Following unilateral cataract surgery, the pupil size of the fellow eye decreased from 3.46 mm to 3.17 mm (postoperative week 1, p = 0.003) and 3.08 mm (postoperative month 1, p < 0.001). Anterior chamber depth of the fellow eye increased significantly from 3.16 mm to 3.27 mm (postoperative week 1, p = 0.005) and 3.26 mm (postoperative month 1, p = 0.001). Uncorrected distance visual acuity (UDVA) of the fellow eye improved significantly at postoperative week 1 (p = 0.042) and postoperative month 1 (p = 0.044). Change of UDVA of the fellow eye at postoperative month 1 was significantly correlated with that of the treated eye (p = 0.039). Conclusions Anterior chamber structures changed and UDVA improved in the contralateral eye after unilateral cataract surgery in our cohort. Because fellow eyes were positively affected by monocular cataract surgery, it would be good information if planning for unilateral cataract surgery due to inevitable reasons.

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.
