BACKGROUND: Superoxide disrnutase(SOD) provides a protective defease mechanism against potential cytotoxicity of superoxide radical in the aerobic organism. Although human skin is constantly at risk for developing acute and chronic changes by ultraviolet radiation and phototoxic reactions with exogenous and endogenously procluced photosensitizing molecules, studies in SOD in the human skin are rare. OBJECTIVE: We measured the level of SOD activities in the scar tissues and the normal human skin specimens. This study was to investigate changes of SOD activity by age, sex, and regional differences of SOD activities in the scar issues and the normal skin. METHODS: Aut,hors assayed the level of SOD activit,ies in 32 scar tissues(male 8, female 24) and 11 normal human skin specimens(male 8, female 3), which were obtaine 3 from face/neck(17 and 3 specimens), forearm(only 4 scar tissues), trunk(10 and 8 specimens), and lower extremity(only 1 scar tissue). RESULTS: First, activities of total SOD, Cu, Zn-SOD, and Mn-SOL ere 18.93+5.49, 16.97+55.31, and 1.96+0.90 units/mg proteiii respectively in the scar tissues. Second activities of total SOD, Cu, Zn-SOD, and Mn-SOD were 17.27+7.09, 13.82+6.44, and 3.45+1.07 units/mg protein respectively in the normal skin. Third, the changes of total SOD, Cu, Zn-SOD, and Mn-SOD activities by age and sex were similar each other and three were no significant, differneces between age groups in total, Cu, Zn- SOD, and Mn-SOD activities. Fourth, in sun exposed area and unexposed area there were no significant differences in the scar tissues in SOD activities. But, SOD activite.(total, Cu, Zn, and Mn-SOD) in face/neck were higher than those in trunk and lower extremity in tae normal skin(P<0.05). CONCLUSION: These findings suggest that there are no differences in the intrinsic SOD activities by age and sex in the mature scar tissues and the normal skin. Differences between exposed and unexposed area in the normal skin are due to the induction of exogenous SOD activity by sun-light generation of superoxide radicals. In wound, increased production of leukocyte derived superoxide radicals is the main factor of increased level of SOD activity.

PURPOSE: The purpose of this paper is to discuss the characteristic CT and MR findings in persistent hyperplastic primary vitreous(PHPV) and to compare the detectability of those findings in each modality. MATERIALS AND METHODS: We retrospectively evaluated CT and MR findings in 32 patients with PHPV. Twenty-five patients had CT, 13 patients had MR, and 6 patients had both CT and MR. RESULTS: Major findings of PHPV in 32 patients on both imaging modalities were lens deformity(78%), shallow anterior chamber(72%), heterogeneous vitreous opacity(72%), enhancing hyaloid artery or remnant of fibrotic hand(69%), and microophthalmos(67%). Minor findings were retinal detachment(22%), and vitreous hemorrhage(6%). In MRI, lens deformity(92%) and shallow anterior chamber(85%) were detected most commonly whereas in CT, opaque vitreous(80%) was the most common finding. Findings of enhancing hyaloid vessel or remnant of fibrotic band, considered characteristic of PHPV, were more commonly detectable in MR (85%) than CT(52%). CONCLUSION: Characteristic MR and CT findings of PHPV were lena deformity, shallow anterior chanber, heterogeneons vitreons opacity, enhanciny hgalind artery or remnant fibrotic band, and microphthalmos. MR seemed to be more useful than CT in detecting Globe pathology.

A 67 year old male patients was anesthetized with halothane for a open reduction of the fractured right femur shaft. The patient was admitted to the emergency room after he had cerebra1 contusion and fracture of the femoral shaft by a traffic, accident. Anesthesia was continued for one and a, half hours without any problem. At around one and a half hours of anesthesia, the patient developed cardiac arrest and resuscitation was performed immediately. The patient's life was saved by resuscitation and the operation was completed without any further problem. At the time of the resuscitation, a tension pneumothorax was recognized but anesthesia was continued with immediate, proper management. Closed thoracotomy was performed at the recovery room after anesthesia and the patient recovered from anesthesia without any other problem.

Induced hypotension is a well established adjunct to anesthesia which provides improved operating conditions for a wide variety of surgical procedures without significantly increasing the risk to the patient. Since introduction of hypotensive anesthesia in 1964 by Gardner, there has been a wide choice of methods for inducing hypotension during anesthesia, most of which are based on the concept of arteriolar dilatation. Hypotensive anesthesia was attempted on ten patients for total hip replacements which were done at Gospel Hospital, from Feb. to Oct. in 1979. The patients selected did not have a liver problem, and this was determined by SGOT and SGPT, and without a limit of age or sex. The hypotension was induced with 2~3% halothane, 50% N2O and 50%, O2and the blood pressure averaged for systolic pressure 71. 22 mmHg and for diastolic pressure 50. 09 mmHg, The average duration of the induced hypotension was 57. 0 minutes and the blood loss during operation was 300 ml on average. During the hypotensive anesthesia, the urine output decreased by 27. 0% and during the recovery period from hypotension urine output increased by 20%. On our experience, we can conclude that hypotensive anesthesia provides good operative conditions and can be performed without damage to vital organs and can reduce blood loss during operation.

Localized fibrous tumor is an uncommon submesothelial origin tumor found in pleura most commonly. Sixty five-year-old man with right lower quadrant pain was admitted. He was treated with resection of tumor and was diagnosed as localized fibrous tumor of pelvic cavity. He is now being followed up without any evidence of recurrence for 34 months. This case is presented with reviewing references.

Complications of penile prosthesis include malfunction, infection and patient dissatisfaction. Herein, a rare complication of a retained reservoir having eroded into the bladder after the removal of the penile components of a three-piece penile prosthesis, is reported. A 39-year-old man complained of irritative voiding symptoms. The symptoms had developed 4 years after the removal of the penile components of the prosthesis. The erosion of the reservoir into the bladder was discovered incidentally during the treatment of bladder calculi. The reservoir was removed by an open vesicolithotomy.
