Lipocortin represents a family of similar Ca++ depentent phospholipid-binding proteins capable of blocking the activity of phospholipase A2 (PLA2) in vitro. Generally, these proteins are believed to inhibit the release of arachidonic acid from photopholipids and the formation of lipid mediators such as prostaglandin, leukotriene, and platelet activating factor. Lipocortin 1, initially identified as a glucocorticoid- responsive protein in macrophages and neutrophils has been implicated in transmembrane signal transduction during growth factor-mediated cell proliferation and transformation. To define the synthesis and its regulation, we investigated the expression of lipocortin 1 in both the mRNA and protein level in U937 cell line in the presence of several differentiation factors. The results were as follows. 1. The expression of lipocortin 1 and its mRNA was increased during TPA-induced differentiation of U937 cells to maximum of 2-fold and 5-fold respectively. Both the protein and mRNA levels decreased after 48 hours. 2. With the treatment with IFN-gamma, the expression of CD16 was increased. However, the protein and mRNA levels of lipocortin 1 were, not changed significantly. 3. Neither the dexamethasone or hydrocortisone have any effects on the expression of lipocortin 1 in both TPA-differentiated and undifferentiated U937 cells. The results from this study would give a light on defining the functional role of lipocortin 1 in macro-moncycle cell lineage and possibly some informative clues for the pathogenic mechanisms of the inflammatory diseases.

Mesenchymal Chondrcsarcoma is a rare malignant tumor originally described by Lichtenstein and Bernstein in 1959. Since the original description, several other reports of this tumor have been published, bringing the total numbers of cases in the literature to about Sixty-five. We report a case of Mesenchymal Chondrosarcoma in an 11-year-old boy who complained of a palpable mass in the region of the left iliac crest.

Kawasaki disease is described by fever lasting five days or more, bilateral conjunctival injection, changes of lips and oral cavity, polymorphous exanthema, acute non-purulent cervical lymphadenopathy, and changes of extremities. Atypical Kawasaki disease is defined as fewer than 4 of 6 criteria described above including coronary artery abnormalities. Especially, atypical clinical manifestations of Kawasaki disease appear in infants younger than 6 months old of age. Thus we recommend echocardiography in early infancy who has prolonged fever in order to diagnose atypical Kawasaki disease and treat early. We have experienced three cases of atypical Kawasaki disease with coronary aneurysm who were admitted because of fever and revealed coronary aneurysm on echocardiography.

Various anatomical defects have been described in the surviving co-twin who had stillborn, macerated monozygotic co-twin with disseminated intravascular coagulation. The suggested mechanism was the transfer of emboli or thromboplastic materials of dead fetus to co-twin through placental vascular anastomoses. Multicystic encephalomalacia is the condition defined anatomically by the presence of multiple cavities in the great part of both cerebral hemispheres. The most common pathogenesis is circulatory disturbance caused by neonatal asphyxia during the perinatal period. We experienced two cases of monozygotic twin with deceased co-twin at 26 weeks, 33 weeks of gestation and confirmed the diffuse multicystic encephalomalacia by cranial ultrasonography and MRI in a surviving co-twin. Only one patient has been followed who showed spastic cerebral palsy and severe mental retardation. We report two cases of multicystic encephalomalacia in a surviring co-twin with a intrauterine fetal death and its related literatures.

Between August 1994 and June 1995, seventeen patients diagnosed as having partial or complete ruptures of the anterior cruciate ligament on MRI were managed by non-operative methods. Among them four patients were excluded due to operation during follow-up and the results were evaluated at a one year follow-up. We selected the patients prospectively for non-operative care using the selection criteria of age, degree of instability, activity level and patient compliance. The average age of them was 37.7 years. Initially knee stress test and MRI were checked, and Cybex study and Lysholm knee scoring were done at post-trauma one year follow-up. They were managed conservatively by ROM and muscle strengthening exercises and a brace fitting schedule for three months. Among them, six cases had partial tears and seven had a complete tear initially. At the one year follow-up, five of six cases who had shown partial ruptures, and two of seven cases with complete tears, recovered continuity of the ruptured ACL on MRI. Their Lysholm knee score was 84.4, and the Cybex test showed no difference in muscle power between the injured and uninjuried side. Those patients who had loss of continuity on follow-up MRI showed Lysholm score of 57.4 and decreased muscle power on Cybex study. Although there are still controversies about the adequate management of ACL injuries, our study suggests that conservative management is a viable alternative to surgery as long as the patients are selected prudently. For more concrete results, however, careful analysis based on a longer follow up period is necessary.

Horizontal tear of the meniscus occurs most commonly in older patients. The tear begins initially with a simple horizontal cleavage which divides the meniscus into superior and inferior leaves resembling a fish mouth and which may become a flap or more complex tear with time if subjected to repeated injury. Thirty-four patients(36knees/40menisci) with horizontal tear of the meniscus, treated with arthroscopic partial meniscectomy except in 3 extensive tears at Ulsan University Hospital from Jan. 1993 to Jun. 1996, were analyzed to investigate the factors that may be associated with this type of meniscal tear, and the results were as follows; 1. The tears commonly occurred in labor workers(61.7%) and without obvious trauma history(67.6%), and the average age at the time of surgery was 44 years. 2. The most common site of the tear was posterior horn of the medial meniscus (62.5%). 3. The 40 horizontal tears consisted of 12 horizontaVcleavage(30%), 3 horizontaVflap(7.5%), and 25 horizontaUdegenerative complex tears(62.5%). 4. Degenerative changes were frequently noted in both arthroscopy(69.5%) and roentgenography (72.2%).
