BACKGROUND: bFGF, a member of the fibroblast growth factor family, potently induces vascular smooth muscle cell proliferation and decreased synthesis of the collagens. OBJECTIVE: For further investigation of the effect of bFGF on extracellular matrix homeostasis in the skin, we evaluated the expression of type I and type VII collagen gene at the transcriptional levels. METHOD: We examined that recombinant human bFGF affects the expression of genes involved in ECM synthesis and remodeling in human dermal fibroblasts cultures as judged by Northern blot analysis. RESULTS: The steady state levels of type I and VII collagen gene mRNA were decreased with age dependent pattern up to 0.13 and 0.44 folds respectively. The transcriptional levels of type I collagen mRNA were increased by TGF-B, treatment but markedly decreased by bFGF as well as TNF-a. But there were no synergistic effects bFGF and TNF-a on type I collagen gene expression. The levels of type VII collagen gene expression were increased by both bFGF and TGF-B,. The TNF-a showed slightly antagnostic effects on type VII collagen gene expression. CONCLUSION: The type I and VII collagen gene expression in dermal fibroblasts is clearly subjected to modulation by the cytokines including bFGF with uncoordinate regulatory pathway. In addition to its function of vascular proliferation, bFGF also may play a major role in physiologic skin condition and in repair process such as formation of a stable dermoepidermal junction during skin wound healing.

Pathological study was performed on the 135 cases (137 lesion) of early gastric cancer (EGC) diagnosed during the period from 1970 to 1988. The gastrectomy specimens were obtained from Pusan National University Hospital and Pusan Paik Hospital. The statistical analysis was applied on the point of pathological and epidemiological aspects. The results obtained were summarized as follows: 1) The proportion of patients with EGC of all gastric cancer diagnosed in Pusan area during the period of 1970 to 1974 was 1.3%, those during 1975 to 1979 was 1.7%, those during 1980 to 1984 was 7.8%, and those during 1985 to 1988 was 20.0% respectively. 2) The model age group was 6th decade in both sexes. The average age of patients with EGC was 50. 1-year-old in men and 47. 9-year-old in women respectively. The sex ratio (M/F) was 2 : 1 but it was lower for young people than for old people. 3) The proportion of sites involved by the EGC in the stomach was as follows : the antrum 61%, the body 39%, and the cardia and fundus 0.01%. The intestinal type cancer more frequently involved the lower portion than the upper portion of the stomach. 4) Regarding the distribution of the gross types of EGC, the elevated group (Type I, IIa) accounted for 14%, the flat type (Type IIb) accounted for 4%, and the depressed group (Type IIc, III) accounted for 82%. There was no correlation between the gross type and the depth of the lesion. The elevated group was more frequent in intestinal type than in diffuse type. 5) The size distribution of the EGC was as follows : 46% of the lesions were smaller than 2.0 cm in diameter, 47% were between 2.1 to 5.0 cm, and 7% were larger than 5.1 cm. There was no correlation between the size of the lesion and the gross type. 6) The intestinal type of EGC was 77 lesions (56.2%) and the diffuse type 60 lesions (43.8%). The ratio of both types (I/D) was 1.3 : 1, and it was lower for younger people than for old people. 7) Ten of 135 cases (7%) had lymph node metastases. The metastatic rate of EGC confined to submucosa was much higher than that of EGC confined to mucosa only, but the metastatic rate was not related with the size of the lesion.

The ankle joint is a modified complex hinge joint which plays an important role in weight bearing, walking and standing. Injuries about the ankle joint cause destruction of not only bony architecture but often also the ligamentous and soft tissue component. So the goal of the treatment of ankle fracture is restoring normal relations of ankle mortise and regaining a smooth articular surface. The author have reviewed 84 cases of ankle fractures which were treated through the admission in the Orthopedic Department, In Je Medical College Pusan Paik Hospital from June 1979 to August 1986. The average duration of the follow-up was one year. The results obtained from this study were as follows : 1. The most common type was Danis-Weber type C. Nexts were B and A in order. According to the classification of Lauge-Hansen, the most common type was Pronation-external rotstion(39.2%). 2. In Danis-Weber type B and C, satisfactory result was obtained by operative treatment. 3. Danis-Weber's classification was very practical criteria for treatment of the ankle fracture.

Most obviuos will be the several anatomic differences between the proximal femur of the child and the adult. Fractures of the femoral neck in the children are extremely rsre and usually are the result of severe trauma in 80% of the cases. This accounts for the high frequency of serious associated injuries. In this injury the vascular anatomy changing with age, continuing growth potential and the effect of deforming forces play critical roles in high complication rate and these make treatment difficult. But still any secure guidelines for the treatment of this injury are not established and this is a field which requires more active research and further progress in future. 26 cases treated at Paik Hospital from Jan. 1979 to June 1988 were analyzed in clinical and radiological aspect and the following results were obtained. 1. The commonest type was Cervicotrochanteric fracture in 13 cases(50%),displaced one 21 cases. 2. In Transepiphyseal, Transcervical and Cervicotrochanteric fracture by early reduction and internal fixation, and in Intertrochanteric fracture by conservative treatment we gained satisfactory results. 3. We experienced 2 cases of coxa vara in nonthreaded pin used cases, 4 cases of premature epiphseal closure and 4 cases of avascular necrosis in threaded pin used ones. 4. Complications were developed in 13 cases (50%). These were 5 cases of coxa vara(19.2%) 4 cases of premature epiphyseal closure (15.4%) and 4 cases of avascul necrosis (15.4%). 5. Avascykar necrosis was developed in displaced fracture of Transcervical or Cervico- trochanteric fracture beyond postoperative 1 year. So. we recommend periodic long follow up for evaluation of avascular necrosis.

Hepatocellular carcinoma represents approximately 90% of the primary liver cancers. Recently, its incidence tends to be increased. Thirsty seven cases from 1986 to 1991 diagnosed as hepatocellular carcinoma by resection were analyzed to know their histopathologic feature and related clinical findings. The average age at the time of resection was 53.1 years, with frequent occurrence in third and fourth decades. Microscopically, the trabecular type was the most frequent growth pattern (35.1%) and classic hepatocyte-like cell type was the most frequent cell type (75.7%). The tumors are mainly moderately differentiated and frequently associated with liver cirrhosis. In comparison of cytological differentiation with liver cirrhosis, there was a tendency for well-differentiated tumors to arise in cirrhotic livers more often than poorly differentiated tumors, and the tendency was statistically significant. But differentiation and tumor size did not show significant correlation. Also statistically significant correlations were not observed between the level of alpha-fetoprotein and tumor size, and between the level of alpha-fetoprotein and differentiation.
