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.

9.Medial transposition of the lateral rectus muscle in experimentally induced medial rectus paralysis.
Korean Journal of Ophthalmology 1991;5(1):9-14
When the oculomotor nerve is completely paralyzed, the affected eye shows severe outward displacement and poor cosmetic appearance. Past results of many surgical procedures for oculomotor palsy have been generally unsatisfactory. We tried a new surgical approach experimentally, in which the disinserted lateral rectus muscle was used as an adductor by medial transposition of the muscle. Five adult cats underwent disinsertion of the medial rectus muscle of both eyes to induce iatrogenic medial rectus paralysis. The disinserted medial rectus was removed as far back as possible to prevent reattachment. Then, the right lateral rectus muscle was disinserted and passed beneath the superior rectus muscle and resutured to the sclera 4mm superoposterior to the medial rectus insertion site. After excision of the bilateral medial rectus, a large exotropia of an average 47.6 delta (42.0-55.5 delta) was induced. The medial transposition of the right lateral rectus produced an average 36.6 delta (24.8-45.8 delta) correction of the exotropia. A satisfactory cosmetic result was achieved by this procedure.

Urinary tract infections constitute a large clinical problems that particularly affect catheter indwelling patients, causing morbidity and mortality. To investigate 1) the rate of infection by duration of catheter indwelling in patients of several kinds of disease, 2) the kinds of colonized bacteria and the similarity or difference of the bacterial species cultured in the urine and catheter of same patient, and 3) the comparison of sensitivity to antibiotics of cultured bacteria of both material, bacterial culture and antibiotic sensitivity test were done from urine and proximal tip of catheters in 31 catheter indwelling patients who had been administered, sometimes intermittently, various antibiotics. The rate of bacterial infection increased markedly with the lengthening of catheter indwelling period in urine and catheter cultures, 22.2% and 33.3% at 1 week, both 50% at 2-3 weeks, 78.6% and 85.7% at 4 weeks respectively The results of bacterial culture from both material were same in 27 (87.1%) patients. The gram negative bacteria composed of 41 (89.1%) species in cultured bacteria. The three frequent species were 16 (34.8%) Escherichia coli, 9 (19.6%) Klebsiella pneumonia, and 6 (13.0%) Morganella morgagni. The overall sensitivity of urine cultured bacteria to tested antibiotics showed minor difference from that of catheter, susceptible in 70.4%, and 73.8%, resistant in 28. 6%, and 24.6%, respectively. Almost all of the patients indwelling catheter longer than 4 weeks had bacterial infection or colonization in urine and proximal catheter-tip in spite of preventive administration of antibiotics. The urine culture only may be enough instead of culturing both the urine and proximal catheter-tip in long-term catheterized patients. Routine antibacterial drug administration should be taken into consideration not to be overused in long-term catheter indwelling patients.
