BACKGROUND: The action of ultraviolet rays on DNA causes the main photobiologic response of cells to ultraviolet rays. To study this effect, tritiated thymidine autoradiography was used. Recently 5-bromo-2deoxyuridine(BrdU), an analogue of thymidine, immunohistochemistry has been developed and is used in the detection of synthetic phase cells. Compared to autoradiography, there are several advantages of BrdU immunohistochemistry; a shorter processing time, no requirement of specific facilites. PUVA, the combination method of UVA and Psoralen has lots of photobiologic effects. OBJECTIVE: Using Brdu immunohistochemistry, the effect of PUVA on the DNA synthesis of tape stripped mouse epdermis was studied. METHOD: Mice stripped by adhesive tape for enhancing DNA synthesis were injected intraperitoneally with 50mg/kg of BrdU immediately after stripping and at 6, 12, 14, 16, 18, 20, 22, 24 and 48 hours after tape stripping for decision of the time for PUVA. The skin diopsies were taken and the specimens were stained by BrdU immunohistochemistry. Single systemic PUVA exposure was performed on the stripped epidermis in peak synthetic time after tape stripping. The irradiation dose of UVA was 5J/cm(2). 8-MOP was administered at 90 minutes before UVA irradiation via a feeding tube with the dose of 16mg/kg. Mice were injected intraperitoneally with 50mg/kg of BrdU immediately after PUVA and at 12, 24, 48, 72 hours, and 7 days after PUVA. The skin biopsies were taken and the specimens were stained by BrdU immunohistochemistry. Positively labeled cells were counted per 5mm epidermis. RESULT: The results can be summerized as follows : 1. The mean numbers of BrdU labeled cells of each groups according to time after tape stripping were 11.0+/-4.4 at immediate, 24.0+/-9.7 at 6 hours 31.4+/-18.1 at 12 hours, 55.0+/-16.1 at 14 hors, 25.8+/-9.7 at 16 hors, 44.2+/-15.7 at 18 hors, 47.6+/-15.6 at 20 hors, 33.4+/-12.3 at 22 hors, 38.0+/-16.3 at 24 hors, and 22.0+/-8.2 at 48 hors group. The mean number of BrdU labeled cells was observed at 14 hors after tape stripping (p<0.05). So by tape stripping DNA synthesis was enhanced maximally at 14 hours after tape stripping. 2. The man numbers of BrdU labeled cells of each groups according to time after PUVA were 11.0+/-7.5 at immediate, 32.2+/-13.2 at immediate, 32.2+/-13.2 at 6hors, 26.4+/-13.4 at 24 hours, 18.0+/-3.4 at 48 hours, 40.3+/-8.3 at 72 hours, and 27.8+/-11.0 at 7 days group. The lowest number of BrdU labeled cells was observed immediately after PUVA(p<0.05). The decreasein the number of BrdU labeled cells significantly persisted 48 hours after PUVA(p<0.05). CONCLUSION: The inhibitory effect on DNA synthesis of PUVA might be sustained 48 hours after PUVA. DNA synthesis was recovered at 72 hours after PUVA and sustained for 7 days.

We experience still a number of cases of residual polipmyelitis with severe deformities which have not been treated for more than 10 years in Korea. During the period of January to August in 1970, 40 cases of residual poliomyelitis had corrective operations performed at Department of Orthopedic Surgery, Pusan National University Hospital. Among those Two cases showed extreme deformities of hips and knees, having not been treated at all for past 18 years. There were flexion contractures of hips 50/80(Rt/Lt) and knees 90/90 in case 1 and flextion contractures of hips 75/90 and knees 80/100 in case 2. Various controversial methods of surgical treatment have been described since 1914 when Soutter introduced a procedure for flexion contracture. In case 1 the procedures of Soutter and Yount, division of the hamstring tendons and posterior capsulotomy of knee were performed by the authors. The bilateral contractures were not corrected completely and the residual deformities remained. In case 2 a compelet correction was obtained by release of iliopsoas insertion and supracondylar osteotomy combined with the operations done in case 1. From this clinical observation the authors reached to the conclusion that the release of insertion of iliopsoas muscle and supracondylar osteotomy are the essential procedures for correction of flexion contracture of hip and knee.

In the chronic osteomyelitis of the ilium the infection is often so diffuse that removing all sequestra and small cavities are practically impossible. Either the partial or total resection of the ilium has been thought as a standard method of treatment in these situations. According to authors experience, the partial resection is not sufficient for removing such diffuse lesions, and all the patients that underwent the total resection of the ilium have been suffering from the instability with severe Trendelenburg gait because of the loss of the abductor origin. These results are far from a satisfactory one in modern orthopedic field in which many reconstructive surgeries have been done for the disabled patients. Removal of only one cortex followed with the closed suction irrigation technique are applied in three cases. The result of this operation is as good as that removing the total ilium in controlling the infection, and there are no patients who are suffering from the gait disturbance. The inner or outer cortex could be safely and widely removed without affecting the hip joint of the affected side.

We report a case of anosacral cutaneous amyloidosis in a 74 year-old-man. The skin finding is a patch of the size of a childs palm on the sacral area, consisting of brownish macular lines that radiate frorn the anus. Histopathology revealed defiosits of homogenous eosinophilic mateial s in the papillary dermis. Congo red staining and dylon staining was positive. Immuohistochemical staining using anti SAP antibodies and anti-keratin antibodies showed positive reactions.

Isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament has been thought very rare. We also had experienced only nine cases of above injury in our center during 5.5 years from January, 1976 to June, 1981. Eight cases of them were followed for an average of the thirteen months, but one of them was eliminated from the study because follow-up study was impossible for the case. The purposes of this paper are to present eight cases of isolated avulsion fracture of the tibial attachment of the posterior cruciate ligament and to discuss the causes and mechanisms of the injury and the method of screw fixation for the avulsed fracture fragment. Seven were injured by traffic accident and one by fall on the knee. All cases seemed to be injured by the force directed against the flexed knee which violently stroke the anterior surface of the proximal end of the tibia or inferior portion of the knee and drove it backwards. We found the tear of posterior capsule only in one patient who was seeming injured by extensive force. All cases were treated operatively by means of screw fixation, and excellent results were obtained in five cases, good in two, and fair in one case.

Evaluation and management of the anterior cruciate ligament (ACL) deficient knee pose several problems. For acute injuries, the essential factors are diagnosis of the ACL rupture and associated injuries, and selection of the appropriate method of the management. Until recently, the frequency of complete disruption of the ACL was though to be less than that of the medial collateral ligament. However, there is little doubt that the ACL is the most frequently torn ligament in the knee. Diagnosis may be made with a combination of tests: Anterior drawer, valgus or varus stress test, Lachman, and pivot shift. If the patients is unable to relax because of pain or fear, examination under the anesthesia should be performed. Treatment can be surgical or nonsurgical. Since the ACL is vital to normal knee function, surgical intervention is advisable in the majority of cases of acute disruption. Authors analyzed the records of 58 cases of acute knee ligament injuried patients treated at the department of Orthopaedic Surgery, Kang-Nam St. Marys Hospital, Catholic Medical College and Center, from November 1982 to January 1984, with follow-up range from 6 to 20 months. 1. Among 58 cases, 41(71%) had anterior cruciate ligament injury and 39(67%) had medial collateral ligament injury. 2. The causes of injury were mostly traffic accident (77%) and majority of the patients was in their twenties and thirties of age. 3. Among 41 cases of ACL Injury, 5 had isolated anterior cruciate injury, 27 cases (66%) had associated medial collateral injury, 9 (22%) had associated lateral collateral injury, and 7 (17%) had associated posterior cruciate ligament injury. 4. Meniscal injury was found only in 6 cases (15%); 4 medial and 2 lateral menisci. 5. Majority of anterior cruciate injured patients (71%) had more than 5mm joint openning than normal side in valgus or varus stress radiogram with the knee in extension. 6. In all cases of anterior cruciate ligament injured patients, the Lachman test was positive under the general anesthesia, hut anterior drawer test was positive in 80%. 7. In about 90% of the cases, the anterolateral rotatory instability (ALRI) test was positive and this finding was accentuated when the lateral collateral ligament was torn. 8. Among 41 cases, 16 (39%) had failure at the insertion site, 7 (17%) had tibial spine avulsion, and 9 patients each (22%) had tear at the ligament substance level and had grade II sprain. 9. In twenty-three, primary repair was done, in 9, primary intra-articular recopstruction was performed and 9 were treated conservatively. The result was from fair to excellent almost in all cases.
