Many kinds of genetic changes have been known to be associated with malignant lymphoma and bcl-2, p53 and c-myc are some examples. We investigated the expression of p53 and c-myc protein in follicular and diffuse B cell lymphoma by immunohistochemistry to study the possible role of these proteins in the lymphomagenesis and transformation of the tumor. The rearrangement of bcl-2 oncogene and the immunoglobulin heavy chain gene was searched for in those cases by polymerase chain reaction(PCR). Paraffin-embedded tissues of fifteen follicular lymphomas and 14 diffuse lymphoma cases were used. The results of immunohistochemical staining are summarized as follows: 1) p53 positivity is significantly higher in diffuse lymphoma than in follicular lymphoma(P=0.001); 2) c-myc expression is not increased in diffuse lymphoma compared with follicular lymphoma; 3) PCNA index is significantly higher in diffuse lymphoma than in follicular lymphoma(P=0.03) but there was no statistically significant correlation between PCNA index and p53 positivity(P=0.44); 4) Eight out of 14 cases of follicular lymphoma and 12 of 14 cases of diffuse lymphoma showed rearrangement of the immunogloblulin heavy chain gene; 5) bcl-2 oncogene rearrangement was identified in only one case of follicular lymphoma and all the diffuse type lymphomas were negative in bcl-2/IgH rearrangement. In conclusion, assuming that the follicular pattern of B-cell lymphoma often transforms to diffuse type in later stages, c-myc over-expression might be an earlier event than p53 mutation in the process of tumor progression in B-cell lymphoma. bcl-2/IgH gene rearrangement in follicular lymphoma is a rare finding in Korea compared to that of Western countries.

The isomorphic response of Koebner is a well-known phenomenon commonly associated with psoriafsis, but it has been also descrilbed in conjunction with a host of other disordered. We described five cases of erythema multiforme showing lesions of easily recognizsble Koebnei phenomena. Traumas to the skin do not cause erythema multiforme, however when a patient is in an active stage of the disease, physieal factor such as traumas occuring in normsl daly-life may contribute to the distribution of skin lesions as have been seen in our patients ; clinicians should aware of this point for better understanding of clinical features in erythema multiforme.

Although heterotopia of pancreatic tissue is a developmental anomaly found in approximately 2% of all autopsies, pancreatic tissue within the thorax and mediastinum is uncommon. In most of these instances, the pancreatic tissue is a component of gastroenteric duplication cysts, intralobar pulmonary sequestrations or teratomas. We describe an anterior mediastinal cyst consisting entirely of pancreatic tissue. A previously healthy 27-year-old woman was admitted due to chest pain during deep inspiration. The computed tomographic scan of the thorax showed a large cyst occupying the right anterior mediastinum. The excised multilocular cystic lesion measured 12 cm in maximum diameter and contained a brown, turbid fluid. The wall was fibrotic and showed a haphazard mixture of ducts and exocrine acini without islets. The histogenesis of this lesion is unclear.

A clinical analysis was done on forty-five patients with fracture of the femoral neck, who have been admitted and treated at our orthopedic department during the period of 6 years, from January 1975 to December 1980. The following results were obtained: Age over 60 comprised 60% of the patients. Male to female ratio revealed no significant difference, being 21 to 24. However, with advancing age, female was affected more frequently than male. The major cause of injuries were “fall or slip down” occuring in 33 patients (73.3%) and “hit by car” in 12 patients (26.7%). Of the 39 patients in whom Garden's calssification of fracture could be applied. Stage II was the most common type occuring in 29 patients (75%), followed by Stage N in 6(15.4%), and Stage 5 in 4 (10%). Of the total 45 cases, forty patients were reduced and fixed with multiple Knowles pins and two patients with Jewett nail. Three patients with neglected treatment of the fracture for over 1 to 4 months were treated with primary replacement arthroplasty of the femur in two and total hip replacement in one. Fractures were united within 3 months in 10 patients (23%), 4 to 6 months in 19 patients (45.2%), and non-union in 2 patients. Relationship between accuracy of reduction using Gardens alignment index and develepment of avascular necrosis was evaluated. Of the 27 patients with reduction in the range of 155 180 in both frontal and lateral views, 3 patients were developed avascular necrosis, and of the 9 patients with reduction of less than 155 in frontal view or greater than 180 in lateral view, 4 patients were developed avascular necrosis.

The incidence of pelvic fractures with or without dislocation of the sacro-iliac or symphysis pubis, is continually increasing. Such injuries not only are serious but can result in disabling complications and deaths. The author reviewed 57 cases of Malgaigne fractures treated at the orthopedic department of Kyungpook National University Hospital during the period from January 1978 to December 1977, and analized as to the cause of injury by mechanical forces, type of fracture, average duration for treatment and complications. We have adopted the classification of unstable fractures of Dunn and Morris. The fractures were classified as followes: vertical shear, 11: bucket handle, 8: lateral compression, 6: straddle, 5: total pelvic disruption, 4: dislocation, 3. Twenty-four patients were male thirteen, female. Traffic accident caused the injury in twenty-seven of the patients, accident of mine and factory, each three. Two fell from heights. Frequent associated soft tissue injuries were rupture of bladder (6 patients) and rupture of urethra (10 patients) The principle of treatment consisted of skeletal traction through the lower limb (supracondyle of femur) on the involved side and balance skin traction on the normal side. Pelvic sling were used. In lateral compression type, reduction was obtained by application of lateral skeletal traction with pelvic screw. Traction was continued for eight weeks. After discarding the traction physiotherapy start in bed and continued for further four weeks. Complete reduction of the displaced fragment and an adequate period of immobilization in recumbency is necessary to obtain the best results in treatment of Malgaigne fractures.
