This study was undertaken to investigate the effect of superoxide dismutase(SOD) to sunburn cell production and development of UV-induced ear swelling reaction in mouse skin after ultraviolet irradiation. In this study, a total of 60 ICR female albino haired mice were used and divided into two groups, A(UVB: 150mJ/cm) and B(UVB:300mJ/cm). Groups of mice were injected intravenouly with SQD(300mJ,/1000cm) just befare UVR and after completion of UVR. The results were as follows . 1. The number of sunburn cells was significantly decreased by injection of SOD (300ug.1000ug)(p<0.05). 2. The number of sunburn cells in a group of mice which was given SOD 1000ug was significantly decreased more than in SOD 300pg(p<0.05). 3. Ear swelling reaction was not significantly suppressed by injection of SOD(300 Pa. 100SC)(p<0 05)

Adenoma of the nipple is a benign tumor of the lactiferous ducts of the nipple which frequently causes erosion of the surface. It can clinically mmic Paget's disease and histologically be misdiagnosed as a well-differentiated adenocarcinoma. A 20-year-old woman developed an erythematous oozing patch on the right nipple two years ago, which subsequently developed iiito verrucous surfaccd papules. A biopsy specimen of the lesion showed focal acanthosis of the epidermis. The tumor was composed of fairly well-circumscribed, glandlike structures within the nipple stroma. Ductlike struciures, papillary areas, solid nests of cells and cysts lined by squarnous epithelium, could be seen, Two cell types lining the ducts were recognized; inner columnar cells and peripherally located cuboidal cells. Although simple excision of the adenoma is the treatment of choice, our case was treated successfully by electrucoagulation.

In 1983, Nora et. al. reperted 35 cases of bizarre parosteal osteochodromatous proliferations of the hands and feet. All lesions occured on proximal phalanges, metatarsals, or metacarpals. The gross appearance was typically that of a small osteochondroma. Radiologically, the proliferations lacked both central continuity of the tumor with the underlying osseus medulla and flaring of the adjacent cortices. Histologically, the lesion exhibited marked proliferative activity, irregular bohy cartilaginous interface, and enlarged, bizarre, and binucleate chondrocyte. The authors experienced a case of bizarre parosteal osteochondromatous proliferation of the right foot in a 61 year-old female which arised from the proximal phalanges of second toe, hostologic and radiologic findings were consistent with the bizarre parosteal osteochondromatous proliferation. The mass was treated by excision, and neither recurrence, nor malignant change was observed up to one year follow-up period.

Longitudinal growth acceleration of the femoral shaft after fracture in children has been recognized since the late nineteenth century, Orthopaedic surgeons have attempted to compensate for the leg length discrepancy by allowing union to occur with some degree of shortening, but logitudinal overgrowth following fractures of the tibial shaft in children has been rarely studied. Thirty-one children, treated for fracture of the shaft of tibia, were studied prospectively to assess the consequent increase in longitudinal growth of the tibia. The material presented in this paper is the result of the study of thirty-one children with fractured tibia who were treated in the Department of Orthopaedic Surgery of Kangnam Sacred Heart Hospital of Hallym University, since 1986 October, the age of the child varied from 3 years to 13 years, these cases have been followed from 30 months to 40 months. We have made a radiologic study of fracture of the tibial shaft with a view to analysing the results according to a number of factors, including the sex and the type, site and degree of overriding of fracture, and method of treatment, and then the degree of overgrowth was compared with unaffected side. 1. The average tibial overgrowth following tibial shaft fracture is 7mm. 2. Growth of the femur was not affected by the tibial fracture.

The study was undertaken to evaluate the heat resistance by split dose hyperthermia in various time intervaland temperature. For the experiments, 96 mice were divided into 2 groups: the first, 36 mice were used to evaluatethe skine reaction of mouse tail to single dose hyperathermia, the second, 60 mice were used to evaluate heatresistance by split dose hyperthermia in variuos time intervals. The results obtained are summarized as follows;1. The ND was 101 minutes at 43degrees centigrade(C) and 24 minutes at 45degrees C. 2. For a 1degrees C increasein temperature, a half in time was required to same degree of skin reaction. 3. Heat resistance was significantlydeveloped in split dose hyperthermia at 43degrees C and 45degrees C. 4. Development, maximum and decay of heatresistance were constant regardless of change in temperature. In summary, heat resistance in split dosehyperthermia is important in study and clinical application of heat therapy in malignant disease.

Osteochondritis usually occurs in the epiphyseal center of children. Common sites of involvement of osteochondritis are the femoral head, tarsal navicular, talus, lunate, but the patellar involvement is rare. The exact cause of osteochondritis is unknown but it is believed to be traumatic or nontraumatic (idiopathic) in origin. This disease was first described by Kohler in 1908 and characterized by radiographic finding of increased density in the patella We have experienced here one case which is believed to be osteochondritis of the patella.

The determination of the degree and ability of recovery of obstructive hydronephrosis is important in treatment and prediction of prognosis. Among the various methods in determination of the status of kidney, intravenous pyelography is the most important tool to evaluate the morphological and functional changes of kidney in vivo. The purpose of this experiment was the determination of process and recoverability of hydronephrosis depend on duration of unilateral uretreal obstruction. For the experiment, 32 rats were divided into 2 groups; the first group of 12 rats were used to determine the process of hydronephrosis during 1 to 4 weeks of unilateralureteral ligation and the second group of 20 rats were used to determine the recoverability of hydronephrotic kidney depend on same duration of ureteral ligation following relief of ligation. Intravenous pyelography as undertaken and renal angiography, gross and microscopic examination were added. The results obtained are summarized as follows; 1. Kidney enlargement and pelvic dilatation were progressively increased with a relation to duration of ureteral obstruction until 4 weeks. 2. Renal excretory function is not impaired until 3 weeks obstruction, but rapidly impaired to nonfunctioning in 4 weeks obstruction. 3. Renal recovery was possible following relief of ureteral ligation within 3 weeks of ureteral obstruction, but histopathological and functional recovery were impossible in 4 weeks of ureteral ligation. 4. There is no direct correlation between duration of obstruction and recoverability following relief within 3 weeks of uretral obstruction. 5. Intravenous pyelographyis a simple and accurate method to determine the degree of obstructive hydronephrosis and to evaluate morphological and functional recovery of kidney following relief of obstruction.

BACKGROUND: Many factors determine the distribution of local anesthetics in the subarachnoid space. These major factors are dosage of local anesthetics, baricity of local anesthetics, position of patient, contour of vertebral column. The temperature of local anesthetics alters the baricity of local anesthetics. At 20oC, the density of 0.5% plain bupivacaine is 1.0003 and generally act as isobaric solution in the CSF. As its temperature lowers, its baricity increases. METHODS: Forty patients (A.S.A I and II) scheduled for lower extremity operation under spinal anesthesia were randomized into four groups; group I (37oC 0.5% bupivacaine, sitting position), group II (37oC 0.5% bupivacaine, 15o head-down position), group III (4oC 0.5% bupivacaine, sitting position), group IV (4oC 0.5% bupivacaine, 15o head-down position). The patients were placed in the sitting position (Group I, III) or lateral decubitus (Group II, IV) and dural puncture was performed at the L3-4 interspace using a midline approach (25-gauge Quincke spinal needle). A free flow of clear cerebrospinal fluid was obtained before administration of drug (37oC 0.5% bupivacaine in Group I, II and 4oC 0.5% bupivacaine in Group III, IV). Patients remained in the sitting position or 15o head-down position for 3 minutes after injection. Patients in each group received a solution that had been previously equilibrated in a stove to 37oC and in a refrigerator to 4oC for more than 1 day. Syringes used to administer the bupivacaine solution were also equilibrated to 37oC and 4oC, respectively. We checked sensory block level using pin-prick test at every 5 minutes. RESULTS: There was statistic significance in sensory block level between Group I, IV and Group II, III. The maximum sensory block level and the time to maximum cephalad spread of analgesia was the T4 level and 9.6 minutes in Group I, the T5 level and 13.5 minutes in Group IV compared to the T9 level and 21 minutes in Group II, the T10 level and 18 minutes in Group III. CONCLUSIONS: The temperature of 0.5% plain bupivacaine affects sensory block level and time to block. It is concluded that the temperature of the injected solution plays an important role in the sensory spread of 0.5% plain bupivacaine.

The purpose of this study are to delineate the temporal and spatial changes of bone mineralization at the distraction gap and adjacent parent bone, and to investigate the effect of microaxial dynamization on regenerate bone healing and on development of regional osteopenia at the adjacent parent bone, during callotasis. Sixteen Korean adult mongrel dogs underwent bilateral tibial lengthening by callotasis. To the right hindlimbs, no dynamization was applied and served as control group (group I, and axial elastic dynamization was conffered to the left hindlimbs (group II). Bone mineral density(BMD) was measured by dual X-ray absorptionmetry(DXA) at immediate post-operative day, post-operative 12 day, 22 day, 36 day, 50 day, 65 day, and 85 day. Quantitative computed tomogram(Q-CT) was also taken after sacrifice to analyze temporal changes of mineralization pattern in the distraction gap. The following results were obtained; 1. In both group I and II, the BMD was lowest at the interzone in the distraction gap and increased linearly toward the corticotomy surface. This pattern did not change with time until the consolidation of the distraction gap, but the difference of BMD between the interzone and adjacent parent bone decreased with progress of consolidation. 2. During the distraction period, BMD increased progressively at the distraction gap and adjacent parent bone in both group I and II. During consolidation period, although BMD of the distraction gap still increased progressively, that of the adjacent parent bone decreased progressively in group I; the more distant from the corticotomy surface, the more decreased the relative BMD. in group II, the decrease in BMD of the adjacent parent bone was less than that in group I which was statistically significant in mid-consolidation period. In conclusion, the new bone in the distraction gap during callotasis appeared to form in bilateral direction with linear gradient from interzone toward corticotomy surface. Dynamization during callotasis not only stimulated regenerate bone healing in the distraction gap, but also prevented the occurrence of transient regional osteopenia at the distant part of the adjacent bone during midconsolidation period.
