BACKGROUND: Sulfonylurea is recommended to be taken before meal. But since premeal administration is against Koreans usual medication habit, it can be the cause of poor compliance. Such recommendation is based on the results of a few clinical trials about appropriate medication time. But most of the clinical studies had a limitation : observe only acute effects of medication, subjects were only healthy volunteer. So the chronic effect of sulfonylurea of each kind must be validated. METHODS: From 1996 May to 1996 July, data were collected from diabetic patients who visited an university hospitals for managing diabetes and used a intermediate-acting sulfonylurea. The subjects were randomized to two groups of premeal group and postmeal group, by chart number and were asked to take the previous medicine according to assignment. After 1 month medication, mixed meal tolerance test was done with 300Kcal carbohydrate, 400+/-50Kcal diet. The subjects were switched to the other group and 2nd mixed meal tolerance test was done 1 month later. The Area under curves was calculated in preand post-prandial glucose curve and was compared by paired t-test. RESULTS: During the study period, total 16 diabetic patients were enrolled. There was no significant statistical difference between pre-prandial group and post prandial group in AUC. CONCLUSIONS: Intermediate-acting sulfonylurea can be administered at any time in relation to meaL.

Allergic contact dermatitis is a prototype of delayed hypersensitivity reaction. Langerhans cells, keratinocytes and T lyrnphocytes play major roles in the pathogenesis of allergic contact dermatitis. We observed Langerhans cells and keratinocytes in contact sensitized epidermal sheets of mice and performed mixed epidermal cell lymphocytes reaction with normal epidermal cells and contact sensitized epidermal cells to determine the lymphocyte stimulating capacity of contact sensitized epidermal cell. We obtained following results : 1. The Langerhans cells were decreased in number and morphologically damaged in contact sensitized epidermis. 2. Ia antigen expression on keratinocytes was detected in almost all contact sensitized epidermal sheets. 3. The allogeneic lymphocyte stimulating capacity of contact sensitized epidermal cells was greater than that of normal epidermal cells. 4. The allogeneic lymphocyte stimulating capacity of contact sensitized epiderrnal cells was lost after treatment of epidermal cells with anti Ia antibody and complement. From these results, it is conceivable that the contact sensitized epidermal cells can amplify the immune reactions by stimulating the lynphocytes which are infiltrated in contact sensitized epidermis.

Two cases of Bleeding Meckel's Diverticulum Using (99m)Technetium-Pertechnetate Scanning are presented. (99m)TC-pertechnetate was used in the diagnosis of Meckel's Diverticulum by Jewette et al in 1970 for the first time. The affinity of this isotope for the parietal cell of the gastric mucosa makes it ideal for delincating ectopic gastric tissue. It noninvasiveness can be used in early screening test of occult gastrointestinal bleeding in pediatric age group.

Of 2,740 industries in Jeonbug area which are covered by industrial insurance policy, 462 facilities which the accidents related to industry occurred during the year of 1979 were studied, and the results are summarized as follows; 1. The accidents related to industry occurred in 462 industries of the total 2,740 industrial facilities in Jeonbug area as of 1979. 2. The incidence rate accident per 1,000 workers was 34.3(49.2 in male workers and 12.8% in female workers), the frequency rate of the total industries in Jeonbug area was 13.36, and severity rate was 1.3. 3. The frequency rates and severity rates by type of industry in study area were quit different to compare with those of national rates. 4. The incidence rate of construction industry was 223.6 per 1,000 workers, and that of transportation-communication industries were 78.6. 5. The proportion of industrial accidents of 20-24 age group was 22.1 percent of the total accidents, and the proportions decreased according to age increase. 6. The incidence rate in the industry having less than 49 workers was 20.6 per 1,000 workers, that of industry with 50-99% workers was 26.7, that of industry with100-199 was 51.9, that of industry with 200-499 was 80.2 and that of with more than 500 workers was 40.7. 7. The accidents which occurred in the workers with experience of less than one year was 69.4 percent of the total accidents, otherwise, the longer the workers have worked the less accident they have. 8.The most accidents occurred in the shift between 10 to12 o'clock, and 16 to 18 hour. 9. The primary causes of the industrial accidents were found to be collisions, machinery, falling objects and falls. 10. The site of injury by type of industry were quit different, and the major site of injury was finger. 11. The laceration and open injuries of the accidents related to industry were 37.2 percent of the total ceases, and fractures or dislocations were 28.5 percent, and contusions were 6.5% percent. 12. Death rate of industrial accident was 5.0 per 1,000 workers, and those of industry were 47.6 in transportation, 42.8 in construction industry, 24.4 in mine industry, and 2.0 in manufacturing industry.

Concomitant with progressive rise in incidence of loosening of conventional total hip replacement arthroplasty which is mainly due to improper surgical technique and cement fixation, has been increased the incidence of revision. In addition to technical failure, there are many risk factors that effect the loosening, such as young active person, obesity, men, osteopomsis, those with bone stock deficiencies as congenital dysplasia of the hip, and those with previous hemiarthroplasties, etc.. Many experimental and clinical studies have been tried to decrease the incidence of loosening in conventional total hip replacement arthroplasty. One of these trials is the cementless total hip replacement arthroplasty with its simplicity of the surgical procedure. We have experienced 426 hips of the total hip replacement arthmplasty in 396 patients from January 1973 to December 1982, among whom 21 hips in 20 patients who had been undertaken revisional arthroplasty were followed up. The longest follow-up was 7 years and 3 months and the shortest was 2 years, the average being 2 years and 4 months. 1. Ankylosis of the hip and sequeale of the infected hip were most common in primary diseases of our revision cases. 2. Revision with cementless total hip replacement arthroplasty of a loosened conventional total hip replacement arthroplasty appears to be available as an effective alternative. 3. Initial attempt with cementlass total hip replacement arthroplasty to prevent loosening after conventional total hip replacement arthroplasty seems to be preferable for patients with ankylosis of the hip or sequeale of the infected hip, especially who are active and young.

Wiskott-Aldrich Syndrome is an X-linked disorder characterized by recurrent infection, thrombocypenia and eczema. Various defects in cell-mediated immunity and deficient antibody reponse to carbohydrate antigens have been described. We experienced a case of Wiskott-Aldrich Syndrome of 28 months old male patient. He has been suffered from multiple petechiae with bleeding, recurrent pyogenic infections and generalized eczema since 3 months of age. Immunological abnormalities are as follows: 1) Serum IgM was gradually decreased, while IgA and IgE were increased. 2) Antibody response against polysaccharide antigen (PRP) was not observed after 3 times of PRPT immunization. 3) CD4/CD8 ratio was reversed (0.6). 4) Proliferative response of mononuclear cells was significantly reduced, and CMI skin test also showed negative results. A brief review of literature was made.
