We evaluated MR imaging of spondylolytic spondylolisthesis degenerative spondylolisthesis and retrolisthesis in 14, 9 and 20 patients respectively. Sagittal and axial spin echo and gradient echo images were obtained with 25-30cm FOV and 5mm/0.5mm thickness/gap by using spine surface coil. Sagittal images showed defects of pars interarticularis just inside of the pedicles of spines in all the cases of spondylolytic spondylolisthesis with relatively variable signal intensity. Displaced vertebrae were commonly observed at L5 (8/14) in spondylolytic spondylolisthesis, at L4 (5/9) in degenerative spondylolisthesis and at variable locations in retrolisthesis. The mean length of displacement of vertebrae in spondylolytic spondylolisthesis was about 7mm and less displacement was onserved in degenerative spondylolisthesis and retrolisthesis. Seven, four and six cases of pseudobulging of disk at displaced level were observed in cases of spondylolytic spondylolisthesis, degenerative spondylolisthesis and retrolisthesis respectively. Seven, five and 14 cases of true disk lesions were onserved in cases of spondylolytic spondylolisthesis, degenertive spondylolisthesis and retrolisthesis respectively. Grade II neural foraminal stenoses (obliteration of one half epidural fat of neural foramen) were commonly (8/14) seen in spondylolytic spondylolisthesis, however the other two types showed less severe neural foraminal stenosis. In conclusion, MR imaging is a highly accurate method for the diagnosis and evaluation of spondylolisthesis and associated lesions of spine and disks.

The authors evaluated high resolution computed tomographic (HRCT) findings of the isolated rabbit lungs with paraquat poisoning, and the findings were correlated with pathologic specimens. The purposes of this study are 1) to obtain the HRCT findings of the normal rabbit lung, 2) to find out if pulmonary pathology can be induced in rabbits by paraquat, and 3) to correlate the HRCT findings to those of pathology. Thirty rabbits were divided into three groups: group I included four control rabbits; group II included 16 rabbits given paraquat intraperitoneally(IP group); and group III included 10 rabbits given paraquat intravenously(IV group). The rabbits were sacrificed seven, 10 and 14 days after injection of various amount of paraquat, and then the lungs were isolated for HRCT and pathologic studies. Gross and microscopic findings of the three groups of control and paraquat-injected rabbit lungs were correlated with HRCT findings. Pulmonary congestion, mild thickening of alveolar walls and septae, and multifocal micro-atelectasis were the main pathologic findings of the lungs in both groups of the rabbits. Pulmonary hemorrhage was noted in five (31%) of 16 rabbits of IP group and three (30%) of 10 IV group. Pulmonary edema was seen in one rabbit (6%) of IP and four (40%) of IV group. Typical pulmonary fibrosis was seen in one rabbit of IP (6%) and IV (10%) group, respectively. There was no correlation between the amount of paraquat and frequency of the pulmonary pathology. Pulmonary fibrosis was seen at least one week after the paraquat injection. On HRCT, pulmonary hemorrhage and edema appeared as diffuse air-space consolidation and pulmonary fibrosis as linear or band-like opacities. However, minimal changes such as mild congestion.

Though basal cell carcinoma is the most frequent and increasing malignant tumor of the skin in Korea, its pathological analysis has been done only on the small numbers. So, we did a comprehensive pathologic study on the 283 patients with basal cell carcinoma diagnosed in the Department of Pathology, Seoul National(233cases) and Chung-Ang(50cases) University Hospital during 1975-1992. The age distribution was ranged from 15 to 84 years with highest incidence rate in the age group of 5th-8th decades and 83.7% of all patients were over 40 years of age. Sex difference was not noted. The most common site was face occuring in 235 out of 283cases(83.0%) especially in the eyelid(25.5%), nose(17.9%) and cheek(16.6%). The most frequent histopathologic type was solid type(54.0%) followed by mixed(23.9%), adenoid(7.5%), and metatypical(4.7%). Among 51 mixed type, all showed solid components with adenoid(51.0%) followed by morphea(25.5%) and metatypical type(13.7%). And among 14 recurrent cases, solid type is found in 50% of cases. The characteristic clinicopathological findings are solid arrangement of tumor cells with various histological pattern and predominant occurence on the face.

Hurthle cell tumors are an infrequent neoplasm of the thyroid gland in adults. Hurthle cell tumors represent 4. 5% to 10% of all primary thyroid epithelial neoplasms in the foreign literature. It has been known as Hurthle cell tumor since Ewing was the first to use this term in 1928. Tumor occurring in an infant was described by Symmers(1941) and Morrow(1945). The authors experienced a case of congenital Hurthle cell tumor of the thyroid gland in a 2 months old boy. He was admitted to the pediatric surgical department because of a growing mass in the neck since birth. Ultrasonogram showed a huge lobulated homogenous solid mass with medium level echogenicity in the region of the thyroid gland. Subtotal thyroidectomy of right lobe and total thyroidectomy of left lobe were done. The specimen measures 2x3x1.5 cm and 7x3x3 cm, respectively. It was an encapsulated, yellow gray firm and solid mass. The cut surface was smooth, glistening and homogenous. Microscopicully, the tumor was composed of tightly packed regular follicles lined by polyhedral, cuboidal, large cells with a granular acidophilic cytoplasms. The nuclei are vesicular, usually only a little bit larger than those of normal thyroid cells.

PURPOSE: This study aims at confirming the effects of the chest meridian massage on the post-anesthetic recovery of general anesthesia appendectomy patients. METHOD: The research was post-test designed as a nonequivalent control group among quasi-experiments tested. The data was collected from June 20, 2003 to October 14, 2003 at a hospital in P city. In the collected data, using SPSS Win 10.0 program, these general features were analyzed by real numbers and percentages; the homogeneity among variables by chi2-test and t-test and the research hypothesis by the t-test. RESULT: Hypothesis 1; The experimental group receiving the treatment of the chest meridian massage will have a much higher post-anesthetic recovery score than that of the control group not receiving it was supported(t=2.544, p=.014). Hypothesis 2; The experimental group receiving the treatment of the chest meridian massage will have a much shorter time of stay in the recovery room than that of the control group not receiving it was supported(t=-4.919, p=.000). CONCLUSION: According to these results, it may be concluded that Chest Meridian Massage is effective in producing a higher level of post-anesthetic recovery score and helps appendectomy patients reduce the time of stay in the recovery room. Therefore the chest meridian massage can be considered as an intervention therapy for directly nursing general anesthesia appendectomy patients.

The purpose of this study was to observe mandibular condyle shape and position in an asymptomatic population. In o rder to carry out this study, 142 temporomandibular joints in 71 adults(35 males, 36 females), who were asymptomatic for temporomandibular joint disorders and had no history of prosthodontic or orthodontic treatments, were selected, and rad iographed using the Accurd-200 head holder(Denar Co., U.S.A.) for lateral individualized corrected tomograms. Mandibular condyles were classified morphologically and evaluated in positional relationships with articular fossae and articular eminences at centric occlusiohn and 1 inch mouth opening. The obtained results were as follows : 1. In the classification of mandibular condyle shape, the convex type was more prevalent in trascranial radiograms and tomograms taken at medial, central, and lateral locations. 2. In the mandibular condyle position at centric occlusion, the mandibular condyles were palced posterior to the center of articular fossae in trascranial radiograns and anterior to the center of articular fossae in tomograns taken at medi al, central, and lateral locations. 3. In the mandibular condyle position in right and left TMJs at centric occlusion, the mandibular condyles were placed bilateral asymmetric relationships to the articular fossae in trascranial radiograms and tomograms taken at medial, cent ral, and lateral location, 4. In the mandibular condyle position at 1 inch mouth opening, the mandibular condyles were placed anterior to the arti cular eminences in trascranial radiogramas and tomograms taken at central location and posterior to the articular eminen ces in tomograms taken at medial and lateral locations.

The neuromuacular blocking effects of the repeated bolus injection and continuous injection of vecuronium have been compared in 20 patients by means of evoked twitch tension. Group I received a loading dose (0.08 mg/kg) of vecuronium and followed by maintenance doae (0.02 mg/kg) when twitch tension had recovered to 25% of control. Group II received a loading doses (0. 08mg/kg) of vecuronium plus a continuous infusion delivering 0.06 mg/kg/hr. Anesthesia was maintained with nitrous oxide, oxygen and 1.5% enflurane. The neuromuscular blocking effect were reversed by the neostigmine 1.0 mg and robinul 0.2 mg when twitch tension had recovered 25% control in both groups near the end of operation. With repeated injection of vecuronium (group I), the duration of blockade of 25% recovery was 21.6+/-4.2 minutes and the recovery times from 25% to 75% was 6.8+/-1.9 minutes The continuous infusion of vecuronium (group II) produced consistent neuromuscular blockade at the average level of 90% twitch depression. The times from the end of infusion to 25% and fr,om 25% to 75% are averaged 16.0+/-2.5 and 4.2+/-0.7 minutes respectively. The reeovery index was more rapid in infusion group than maintenance group (P<0.05).
