In an attempt to elucidate the pathological changes following common bile duct ligation, the present study was undertaken in male Sprague-Dawley rats. Morphologic studies of the livers were performed at 1, 2, 3, 5, 7, 9, 11, 13 and 15 weeks after common bile duct ligation. In an attempt to clarify the relationship between the process of bile duct formation and the nature of primitive cells observable around the primitive biliary structure, light microscopic, immunohistochemical and electron microscopic studies were performed. The results were noted as follows: 1) Light microscopically, proliferation of biliary cells began in the periphery of portal areas and expanded toward hepatic lobules. In severe cases of biliary structure proliferation, hepatocytic cords and classic hepatic lobules were inconspicuous. 2) Immunohistochemically, CK-19 expression was limited to biliary structures in protal areas and proliferated biliary epithelial cells. In the serial sections of paraffin block, proliferated intrahepatic biliary structures were associated with those of portal areas. Some oval cells in the ductular hepatocytes were stained for both CK-19 and MNF 116. 3) Ultrastructurally, the proliferated biliary epithelial cells divided into three patterns: absence of lumen, formation of incomplete lumen, and formation of complete lumen. Furthermore these patterns had spectral continuity of maturation in their structures. 4) In some biliary structures, individual biliary cells pushed the basement membrane toward neighboring tissue with accompanying destruction of basement membranes, patterns of budding. Sometimes these cells and hepatocytes comprised the same lumen. In summary, the results obtained by the present study indicate that proliferated biliary structures may be derived from the preexisting intralobular or portal biliary system.

Rotatory Instability of the permitting abnormal external totation of the tibia on the femur is the result af forced abduction of the flexed knee and external rotation of the tibia. The basic lesion is a tear in the medlal capsular ligament. The authors have reported clinical study in 40 patients with medial collateral ligament injuries who were treated by operative methods in the Orthopedic Department at the Taegu Presbyterian Hospital from January 1973 to Octdber 1979. of 40 patients, pes anserinus transplantation was performed on 15 patients and direct repair on 25 patients. The results are as followings: 1. All the patients were seen with a complete rupture of the medial collateral ligament and of these 45% had rupture of the femoral attachement. 2. Exellent to good result were more often obtained in recent injuries of less than 2 weeks rather than those in older Injuries. 3. Exellent to good result were more often obtained in the groups of Pes Anserinus tranplantation than the groups of direct repair. 4. In all cases of groups of pes anserinus transplantation, permanent sensory palsy af the patellar branches of the saphenous nerve was present due to the location of the surgical incision.

l6-year-old male and 48-year-old female with systemic lupus erythematosus (SLE) and renal disease presented with vesiculobullous eruptions during severe attack of the disease. They showed hypocomplementernia, and high ANA titers. Histopathologic findings revealed subepidermal blister and leukocytoclastic vasculitis, Direct immunofluorescence demonstratedlinear deposits of IgG, IgA and lgM at the dermoepidermal junction. The vesiculobullous eruption of SLE may be an important marker reflecting disease activity and prognosis.

BACKGROUND: We investigated the effectiveness of fibular strut allograft augmentation of proximal humerus fractures to prevent varus deformity in patients over the age of 65 years with insufficient medial support. METHODS: We analyzed the clinical and radiological outcomes of locking plate fixation with adjunct fibular strut allograft augmentation in 21 patients with proximal humeral fractures. The inclusion criteria were age (65-year-old or older); presence of severe medial comminution; inadequate medial support; and those who could participate in at least a one year follow-up. The average age was 76.4 years. We analyzed each patient's Constant score, our indicator of clinical outcome. As radiological parameters, we analyzed time-to-bone union; restoration of the medial hinge; difference between the immediately postoperative and the last follow-up humeral neck-shaft angles;; and anatomical reduction status, which was assessed using the Paavolainen method. RESULTS: A successful bone union was achieved in all patients at an average of 11.4 weeks. We found that the average Constant score was 74.2, showing a satisfactory outcome. The average difference in the humeral neck-shaft angles between the immediately postoperative time-point and at the final follow-up was 3.09°. According to the Paavolainen method, the anatomical reduction was rated excellent. The medial hinge was restored in 14 of 21 patients. Although we did not find evidence for osteonecrosis, we found that a single patient had a postoperative complication of screw cut-out. CONCLUSIONS: Fibular strut allografting as an adjunct treatment of proximal humeral fractures may reduce varus deformity in patients with severe medial comminution.
