Many factors exert an influence on enzyme activity and thus on the rate of reactions that they catalyse. The most important of these factors are pH, temperature, substrate concentration, and the concentration of some inhibitors present. A solution of the enzyme diastase, which breaks down molecules of the polysaccharide starch to the disaccharide maltose by hydrolysis, was provided. Activity of these enzyme was measured by the rate at which starch was removed from the reaction mixture. These experiments were designed to study this reaction rate under varying conditions and the following results were obtained. 1. The range of optimum pH for this enzyme at room temperature was 4.0-7.0 and the optimum pH was 5.0. 2. The range of optimum temperatures for this enzyme at pH 7.0 was 30-50 degrees C and the optimum temperature was 40 degrees C. 3. The relationship between the enzyme activity and substrate concentration could be expressed by the Michaelis-Menten equation. The limiting velocity of these enzyme at room temperature and pH 7.0 was 415 microgram starch removed/ml of reaction mixture/min and Km, Michaelis constant, was 343 microgram/ml. 4. Inhibitors NaCl and HgCl2 blocked this enzyme activity completely at 1% and 0.01% respectively.

PURPOSE: Osteoporosis is generally regarded as disease of women and there are extensive data about post-menopausal osteopotosis, but there is relatively little information concerning the osteoporosis in aging male. We aimed to determine the relationships between age ,androgen and bone mineral density (BMD) in elderly korean men. MATERIALS AND METHODS: We evaluated the sex hormones and BMD of 82 elderly men between May 1999 and April 2000. Serum free testosterone (FT), total testosterone (TT), DHT, LH, FSH and Prolactin were measured by RIA. BMD at anteroposterior L2-4, femoral neck, ward's triangle, femoral trochanter and femoral shaft were determined by dual-energy X-ray absorptiometry. We defined group I as free testosterone <10ng/dl and group II as 10ng/dl. RESULTS: Serum LH and FSH increased with age. There was a significant decrease in serum FT with age, but T concentrations remained unchanged. There were significant declines with age in BMD at femoral neck, Ward's triangle, femoral trochanter, femoral shaft. Serum FT were significantly correlated to BMD at anteroposterior L2-4, femoral neck, Ward's triangle, femoral trochanter, femoral shaft. After controlling for age, serum FT were significantly correlated to BMD at femoral trochanter, femoral shaft. Mean BMD was significantly lower in group I than group II at anteroposterior L2-4, femoral shaft. CONCLUSIONS: We suggest that FT is a male osteoporotic marker in man older than 50 years and bone mineral density should be considered for diagnosis of male osteoporosis associated with PADAM, especially when FT is lower than 10ng/dl.

Retrospective clinicopathologic analysis of 15 patients with the phyllodes tumors(PT) of the breast, diagnosed at SNUH over 6 years period, was done. By light microscopy, 8 cases were diagnosed as benign, and 7 cases were diagnosed as malignant. Mean ages o the patients were 37 and 34 years in malignant and benign, respectively. Most of those cases were presented with a palpable mass of the breast. None of the patients with malignant PT had distant metastasis, Local recurrences were experienced in 3 patients among the malignant PT, and one patient among the benign PT. One of 7 malignant PT was coexisted with simultaneous ipsilateral infiltrating duct carcinoma. The clinical course was not well correlated with pathologic features. The prognostic significances of several histopathologic parameters were assessed for possible correlation with local recurrence, metastasis and death; stromal cellularity, stromal cellular atypism, mitotic activity, tumor contour, necrosis, tumor size and heterologous stromal elements. Immunohistochemistry using antibody to vimentin, proliferating cell nuclear antigen(PCNA) and epidermal growth factor receptor(EGF-R) were analysed. In the 5 cases of benign PT, the stromal cells stained diffusely positive for vimentin and 3 cases of malignant tumors show similar staining for vimentin. The percentage of PCNA-positive cells were higher in the malignant PT than in the benign ones; they were 3.5% to 60% in malignancy, while they were less than 60% in all benign PT. The results of EGF-R staining were correlated with the histologic classification; only 2 cases out of 8 benign PT show diffusely positive staining of EGF-R in the cytoplasm, but 6 cases out of 7 malignant PT show positive findings.

We reviewed 40 cases of femoral shaft fractures in children treated with split Russel traction and initial fracture angulation above 10 degree. The treatment of femoral shaft fractures in children is various according to age. Satisfactory results have been reported with split-Russel traction. At an average follow-up of 33 months, we obtained following results about remodelling of fracture site & physeal site, possible acceptable angulation of fracture. 1. The average time of traction was 18 days, and hip spica cast was applied for 28 days. 2. Malunion within 25degrees in flexion & 23degrees in valgus & 24degrees in varus was well corrected spontaneously. 3. Average correction of initial angular deformity was 86% at last follow up. 4. Anterior angulation was corrected at 83%, varus 87%, valgus 88%. 5. Remodelling according to direction of deformity was no statistical correlation (P>0.05), and then spontaneous correction of angular deformity was same without relation to direction of deformity. 6. Remodelling according to site was statistical correlation (P<0.05), fracture site 26%, physes 74%. And proximal physes 36%, distal physes 38%.

BACKGROUND: Psoriasis is a disabling and intractable disease influencing the psychosocial life of the patients. Patients who are frustrated with orthodox medicine may explore alternative therapies. OBJECTIVE: This study was done to research on the actual condition of the use of alternative medicine in the patients with psoriasis. METHODS: A self-administered questionnaire was constructed, and was given to the patients to answer our questions. RESULTS: Among 128 patients with psoriasis, 61 (47.7%) reported previous use of one or more forms of alternative medicine. The absence of satisfactory long-term effects of physician-provided therapy was the main reason for patients trying alternative medicine. Persons without skin s disease and the mass media were the main sources of information on alternative medicine. CONCLUSION: Alternative therapies were widely utilized by subjects participating in this study, and dermatologists need to be aware of alternative treatments employed by their patients.

Fiber-reinforced composite(FRC) was developed as a structural component for dental appliances such as prosthodontic framework. FRC provides the potential for fabrication of a metal-free, excellent esthetic prostheses. It has demonstrated success as a result of its simple fabrication, natural colour, and marginal integrity, and fracture resistance of veneering composite resin and the FRC material. Although it has lots of merits, clinical and objective data are insufficient. The purpose of this study was to evaluate the fracture strength and marginal fitness of fiber-reinforced composite bridge in the posterior region for clinical application. Sixteen bridges of each group, Targis/Vectris(R), Sculpture-fibrekor(R)and In-Ceram, were fabricated. All specimens were cemented with Panavia 21 to the master dies. Strength evaluation was accomplished by a universal testing machine (Instron). The marginal fitness was measured by using the stereoscope (X50). The results were as follows. : 1.The fracture strength according to the materials was significantly decreaed in order In-Ceram(238.81+/-82). Targis Vectris(176.25+/-18.93), Sculpture-Fibrekor(120.35 +/-20.08) bridges. 2.FRC resin bridges were not completely fractured, while In-Ceram bridges were completely fractured in the pontic joint. 3.The marginal accuracy was significantly decreased in order Targis/Vectris (60.71micrometer), Sculpture-Fibrekor(73.10micrometer). In-Cream Bridge(83.81micrometer). 4.The fitness of occlusal sites had a lower value than the marginal sites(P<0.001), and the marginal gaps of inner site of the pontic were greater than that of outer sites of the pontic. Fiber reinforced composite bridges are new, esthetic prosthesis and can be clinically used in anterior regions and short span bridges. However, caution must be exercised when extrapolating laboratory data to the clinical situation because there are no long term clinical data regarding the overall success of the FRC.
