This survey was conducted from January 1991 to May 1991. Two hundred and eight residents in 4 government supported homes for the aged and hundred and eleven living in the community in Taegu, Korea, were examined to evaluate the depression and the anxiety of the aged with combined anxiety and depression scale (CADS) and somatization symptom check list (SCL). There are no significant differences between residents in the home for the aged and those living in the community on the total scores of CADS and SCL. However, in the case of the total score of CADS of the female subjects in the home for the aged were significantly higher than those of the community residents. The elderly in the home for the aged tended to have pure depression, while community residents were likely to have anxiety and depression. Fifty-two subjects of home for the aged and sixty-nine of the community scored over 50 points of CADS, which indicates considerable depression or anxiety. In psychosocial factors, the subjects who in the following situations had statistically significant higher scores than others. The results were as follow. Poor health, unhappiness, unsatisfaction to the past occupation, pessimistic thought in future view for both group and unsatisfaction of the relationship with familiar people for the elderly in the community. The SCL scores of two groups subgrouped by under 49 and 50 on CADS showed significant differences between each subgroup on all of the SCL items. It could be suggested that somatic symptoms for the aged is a sign of depression.

We investigated the anti-inflammatory effect of Pyunkang-tang extract (PGT), a complex herbal extract based on traditional Chinese medicine that is used in Korea for controlling diverse pulmonary diseases, on cigarette smoke-induced pulmonary pathology in a rat model of chronic obstructive pulmonary disease (COPD). The constituents of PGT were Lonicerae japonica, Liriope platyphylla, Adenophora triphilla, Xantium strumarinum, Selaginella tamariscina and Rehmannia glutinosa. Rats were exposed by inhalation to a mixture of cigarette smoke extract (CSE) and sulfur dioxide for three weeks to induce COPD-like pulmonary inflammation. PGT was administered orally to rats and pathological changes to the pulmonary system were examined in each group of animals through measurement of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels in bronchoalveolar lavage fluid (BALF) at 21 days post-CSE treatment. The effect of PGT on the hypersecretion of pulmonary mucin in rats was assessed by quantification of the amount of mucus secreted and by examining histopathologic changes in tracheal epithelium. Confluent NCI-H292 cells were pretreated with PGT for 30 min and then stimulated with CSE plus PMA (phorbol 12-myristate 13-acetate), for 24 h. The MUC5AC mucin gene expression was measured by RT-PCR. Production of MUC5AC mucin protein was measured by ELISA. The results were as follows: (1) PGT inhibited CSE-induced pulmonary inflammation as shown by decreased TNF-α and IL-6 levels in BALF; (2) PGT inhibited the hypersecretion of pulmonary mucin and normalized the increased amount of mucosubstances in goblet cells of the CSE-induced COPD rat model; (3) PGT inhibited CSE-induced MUC5AC mucin production and gene expression in vitro in NCI-H292 cells, a human airway epithelial cell line. These results suggest that PGT might regulate the inflammatory aspects of COPD in a rat model.

PURPOSE: The goals of cranioplasty are to protect the brain from trauma and restore normal cranial contour with as few complication as possible. In patient who suffered from cranial defect, the most satisfactory form of cranioplasty may be archived with autogenous bone grafts. We report on the treatment of large frontal bone defect using pericranial flap and split-rib graft. METHODS: A 29-year-old male was referred to our department. He was involved in an automobile accident resulting in large frontal bone and sinus defect and skull basal defect. The reconstruction was undertaken using galeal frontalis myofascial flap and split-rib cranioplasty using bicoronal incision. RESULTS: The postoperative course was successful. For 9 months follow up period, there was no complication about hematoma, infection, CSF leakage and washboard deformity. He was pleased with the results even when absolute symmetry was not achieved. CONCLUSION: We experienced large frontal bone and sinus defect and skull basal defect patient and successfully treated with split-rib graft and galeal frontalis myofascial flap.

In order to achieve a satisfactory esthetic result of periodontal surgery or implant in maxillary anterior area, periodontists must be aware of normal alveolar bone anatomy. The purpose of this study was to evaluate the relationship of alveolar bone morphology to tooth shape and form. 78(mean age : 25 yrs) periodontally healthy volunteers participated in this study. Two maxillary central incisor and one lateral incisor were selected to study. With minimal local anesthesia, guttapercha cone inserted to labial gingival sulcus of selected teeth just after bone sounding with periodontal probe. Metal ball (4mm diameter) attached to palatal fossa of central incisor. Then, periapical radiograph was taken according to long cone paralleling technique. After film scan, labial alveolar bone profile reproduced along interproximal bone and apical ends of gutta-percha cones on computer screen. By utilizing computer program, the distance from height of interproximal bone to the labial bone crest in central incisor-central incisor and central incisor-lateral incisor area was measured and converted to real distance by using vertical length of metal ball on film. After measuring crown length & width of central incisor, the 10 individuals ranked lowest CW/L ratio (crown width/length ratio) and the 10 ranked highest were selected as having a long-narrow(group N), or a short-wide(group W) form of the central incisors. Means of the distance from height of interproximal bone to the labial bone crest of group N, W were calculated and compared by means of independent t-test. The results were as follows: 1. Mean distance from the height of the interproximal bone to the labial bone crest was 3.5+/-0.7mm between two central incisor, and 2.8+/-0.6mm between central and lateral incisor. 2. Mean CW/L ratio of group N was 0.57, and group W was 0.8. Mean distance from the height of the interproximal bone to the labial bone crest of group N was higher than group W in both measured area(measurements of group N, W were 3.9+/-0.2mm and 3.5+/-0.2mm between two central incisor, 3.0+/-0.2mm and 2.8+/-0.2mm between central and lateral incisor), but there were no statistically significant differences when the groups were compared. Within the limits of the present study, there was a tendency that subjects with long-narrow teeth have more scalloped alveolar bone profile than subjects with short-wide teeth in upper anterior area, but no statistically significant differences were found.

Two autopsy cases of asphyxia due to oxygen deficiency are reported. The first case is that a 38-year-old man died in a storehouse. Many pears were stored in a storehouse and the its atmosphere was strictly controlled. The second case is that a 42-year-old man died in the boiler room of a fishing ship. Much amount of Freon gas escaped due to a defect of the refrigerator in the boiler room. The victim entered the boiler room because he repaired the refrigerator. But, the victim died when he entered the boiler room immediately. In this article, the autopsy findings and the contents of the investigation of scene of two cases are described.

OBJECTIVE: After drawing and stacking contour of structures, which are identifed in the serially sectioned images, three-dimensional (3D) images can be made by surface reconstruction. The 3D images can be selected and rotated in a real time. The purpose of this research is to compose software of automatic surface reconstruction for making 3D images. METHODS: Contours of 55 structures in the 613 magnetic resonance images of whole body were drawn to make segmented images. We composed automatic software for stacking contours of a structure, for converting the contours into polygons, and for connecting vertices of the neighboring polygons to fill gaps between polygons with triangular surfaces. The surface reconstruction software was excuted to make 3D images of 55 structures. RESULTS: Virtual dissection software, on which 3D images could be selected and rotated, was composed. CONCLUSION: For other research, this like program can be composed for automatic surface reconstruction; several kinds of commercial software can be used for manual or automatic surface reconstruction. Investigators might choose one of the methods in consideration of their only circumstances.

OBJECTIVE: Cadaver's sectioned images with high resolution and real color could be used as the source of realistic three-dimensional images. If the sectioned images are registered to a patient's MRIs, three-dimensional images with high resolution and real color that fit the patient, can be produced; the three-dimensional images enable realistic virtual surgery for the patient. The objective of this study was to verify the registration of a cadaver's sectioned images to a patient's head MRIs. METHODS: The sectioned images of the heads of cadaver were associated with segmented images selected at 3 mm intervals. The patient had his head MR scanned at 3 mm intervals; the MRIs were segmented. Software to register the cadaver's sectioned images to the patient's MRIs was developed. On this software, the corresponding dots were identified on both the sectioned images and the MRIs either manually or automatically using segmented images. RESULTS: The registered sectioned images corresponded to the patient's MRIs. Both manual and automatic registrations were satisfied. CONCLUSION: Further study is needed for registering sectioned images to actual patients.

BACKGROUND AND OBJECTIVES: External ear resonance (EER) can normally increase the sound pressure level at the tympanic membrane by as much as 20 dB at the frequency between 2 and 4 kHz. Perforation of tympanic membrane (TMP) may alter the resonance characteristics. Surgical modifications of the external auditory canal by tympanoplasty may also change the EER features. We aimed to analyze the EER of patients with the TMP before and after surgery. MATERIALS AND MEHTOD: This study comprised of 130 patients (135 ears) with chronic otitis media. We checked EERs before and after the surgery. The preoperative group was divided into two groups according to perforation size. Postoperatively, the EER was checked at 3, 6, 9, 12 months or after 15 months. We compared these data with the control group which comprised of 96 adult ears. RESULTS: In the preoperative group, the peak resonant gain and the frequency were not different from the control's and the peculiar negative peaks appeared around 1500 Hz in half of the cases. No significant differences were found in the first peak gains according to the perforation size. The negative peaks appeared deeper in the larger perforation group. After tympanoplasty, the gain markedly increased. As time passed, the gain tended to decrease, but did not equalize with the control's data. CONCLUSION: Additional gain should be considered in the frequency of around 1 kHz for hearing aid users with the TMP. We could expect alterations of EER after tympanoplasty, suggesting that these changes should be considered at the time of fitting hearing aids.

PURPOSE: This study was performed to evaluate the aluminum level in hemodialysis patients and to find a correlation between aluminum level and bone specific alkaline phosphatase level. METHODS: Eighty five randomly selected patients with end-stage renal disease, undergoing maintenance hemodialysis treatment over 1 year were studied. Serum aluminum and bone specific alkaline phosphatase concentration were measured. Low dose desferrioxamine test (5 mg/kg) was done. RESULTS: The serum aluminum concentration before and after low dose desferrioxamine test were 4.21+/-2.13 microgram/L and 8.89+/-4.48 microgram/L (p<0.01) respectively. Bone-specific alkaline phosphates and parathyroid hormone concentration were 39.08+/-39.90 mg/dL and 98.27+/-112.92 pg/mL. The aluminum level after desferrioxamine test was correlated with duration of hemodialysis (r=0.238, p=0.03). Aluminum level was not correlated with bone specific alkaline phosphatase level. CONCLUSION: Aluminum level was lower than that of previous studies. Aluminum level was not increased in patients with low bone specific alkaline phosphatase. Thus, it seems that serum aluminum level is not a major problem in hemodialysis patients with lower turnover bone disease. However, confirm diagnosis of aluminum related bone disease in hemodialysis patients needs combined study of bone histology with a large number of cases.

BACKGROUND:With the application of early reperfusion by thrombolysis after acute MI, the importance of nontransmural infarction is increasing. We evaluated 1) the changes of LV dimension, LV fibrosis and transforming growth factor-beta1 (TGF-beta1) mRNA expression in a rat model of nontransmural infarction and 2) effects of angiotensin converting enzyme inhibitor (ACEI) and angiotensin II receptor blocker (ATRB) treatment after nontransmural infarction. METHOD AND RESULTS: Female Sprague-Dawley rats were subjected to 45 minutes of coronary occlusion followed by reperfusion, and at 5 days after the operation, animals were randomized to untreated (MI-vehicle, n=19), captopril-treated (MI-captopril, n=15) and losartan-treated (MI-losartan, n=14) groups. LV dimension, measured by transthoracic echocardiography, was significantly increased at 26 days after MI, and both captopril and losartan treatment inhibited LV cavity dilatation (LV end-diastolic dimension (mm): MI-vehicle, MI-captopril, MI-losartan; 8.6 +/- 0.2, 7.8 +/- 0.2, 8.0 +/- 0.2, p<0.05 vs. MI-vehicle each). Interstitial fibrosis was reduced with both captopril and losartan treatment (p<0.05 vs. MI-vehicle). TGF-beta1 mRNA increased 2.6 fold at 10 days (p<0.05 vs. pre-MI), and normalized at 26 days after nontransmural MI. Captopril and losartan treatment blocked the induction of TGF-beta1 expression after nontransmural MI (p=S vs. pre-MI). CONCLUSION: After large nontransmural MI, ACEI and ATRB treatments attenuate LV remodeling and decrease interstitial fibrosis, at least partly by blocking the acute induction of TGF-beta1 mRNA expression.
