CT may be valuably used indetermination of proptosis. Normal value of eyeball protrusion was measured innormal Koreans using CT. Among 86 Koreans, 26 have normal both eyes, but 60 have one normal eye with one abnormaleye (chiefly, proptosis and and eyeball tumor) The results of 112 eyes are as follows; Absolute measurement of“a”, that is, the distance between cornea & IZL (interzygomatic line) is 16.0±3.4mm in male (for 63 eye),15.7±4.0 mm in female for 49 eyes. Ratio of “a” over “A” (A-P diameter of eyeball) is 57±12% is male (for 63eye), 57±14% in female (for 49 eye) Discrepancy of eyeball protrusion between both eyes is 0.67±1.5mm (for 26adults) Practically, normal range of eyeball prototrusion(“a”) is 12.6mm< male< 19.4mm, 11.7mm

The type-specific PCR and the sequence analysis of 56 kDa gene of Orientia tsutsugamushi infected in field rodents specimens have shown intratypic genetic heterogeneity in genotype Karp. In sequence comparison, this genetic heterogeneity was mainly due to insertion or deletion of a repeated unit in variable domain I (VDI) region. These results suggested that genetic duplication or deletion of the specific sequence rnight be involved in intratypic genetic heterogeneity of Orientia tsutsugamushi.

The retrospective analysis on the clinical utility and side effects of the metrizamide myelography andmetrizamide CT-cisternography were made in 292 patients. Metrizamide CT proved valuable in the diagnosis ofintraspinal neoplasms with total block in myelography, demonstrating the upper margin of the neoplasms in a largenumber(75%) of the cases with neoplasm. Metrizamide study also clearly showed the nature and extent of thesyringomyelia, and arachnoid cyst. Metrizamide CT was also helpful in the diagnosis of spinal stenosis, spinaltrauma and infectious disease of the spine. The most common side effects were transient minor meningealirritations (headache, nausea, vomiting and dizziness)which persisted no more than 48 hours in most of thepatients. Five patients developed major complications such as grand mal seizure, toxic psychosis or asepticmeningits.

It was well known that atrial myocytes systhesize atrial natriuretic peptide[ANP], and secrete it into the atrial lumen through the atrial endocardium. But the mechanism for regulation of ANP secretion has not been clearly elucidated, because there was little information of the atrial morphology concerning basal lamina. Basal lamina is surmised as one of barriers that control the movement of ANP, a large molecule. This study was attempted to elucidate the morphological characteristics of basal lamina and connective tissue fibers of atrial endocardial layer by scanning electron microscopy. Basal lamina was exposed by removal of the overlying endothelium. This was achieved by using OsO4 maceration, immersion in aqueous boric acid or EDTA treatment. After removal of the endothelial cell, the specimens were exposed to ultrasonic vibration in case of need. The external surface of basal lamina showed a fairly smooth appearance on the whole, although a few irregular folds are often encountered. Fenestrations, 0.1-1 micrometer in diameter, were randomly observed on the basal lamina, and they were circular to oval in shape. Margin of fenestrations was somewhat distinct and some was divided into two parts by linear structures. The structural differences of fenestrations between right and left atria were not found. The fibroreticular lamina under the basal lamina was revealed by removal of the endothelial cells and their basal lamina. This layer was consisted of interwoven fine fibers. These fine fibers were repeatedly divided and fused, forming reticular network. Some fine fibers connected with basal lamina. Some connective tissue fibers below fibroreticular layer were collected into thick bundles running parallel to myocytes. Above results may serve as a basis for the physiological and morphological studies of atrium.

As Kelsey stated “Four out of five individuals will have a significant complaint of back painat one time or another in their lives and impairment of the spine are the most frequent cause of time lost from work”., low back pain affects the quality of life for just about everyone, medical and economic impacts of low back pain are enormous. Nevertheless, neither the government not industry has been seriously involved in the study of the cause, prevention, and management of back pain. The purpose of this study was to review and analysis the clinical materials of low back painand draw differences, if any, between discogenic and stenotic low back pain. Three hundreds and fourty nine cases suffering from low back pain and/or sciatic pain, excluded fresh traumatic and inflammatory conditions of the spine, have been admitted and treated at Dept. of orthopaedic surgery, Eul-Ji General Hospital, Dae-Jeon from May, 1981 to April, 1984. They were consisted of H.N.P. (172 cases), Spinal stenosis (61 cases), Spondylolisthesis (42) cases), Degenerative joint Disease of the spine (48 cases), and Others (26 cases). Among them, two hundred and twenty six cases who were followed more than four months were mainly subjectecl to this study.
