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.

In order to exmaine the mutagenicity of cadmium dichloride the author studied the induction of sister chromatid exchanges in chinese hamster ovary K1 cells which treated with cadmium dichloride at various concentrations. The results obtained were as follows: 1. In cells treated with 10(-4) M cadmium dichloride, a small number of cells were visable but no mitosis was bound. 2. The frequencies of sister chromatid exchanges in cells treated with 10(-5) M and 10(-6) M cadmium dichloride as 10.7 +/- 1.9 and 8.3 +/- 2.1, respectively, were significantly increased for control (6.0 +/- 2.3). (p<0.05). 3. There were dose-dependent relationship between the concentration of cadmium dichloride and frequency of sister chromatid exchanges in cells treated with cadmium dichloride at concentration ranging from 10(-5) to 10(-7) M.

While for the last thirty years Dapsone (4,4, diaminodiphenyl sulfone; DDS) has been the chemotherapeutic treatment of choice in the management of leprosy, other non-sulfone compounds have been used when patients have shown either sulfone resistance or sulfone sensitivity. Unfortunately, however, there have gradually appeared a significant number of dapsone resistant and non-sulfone resistant patients (i. e., patients resistant to the conventional chemotherapeutic management of leprosy), thus necessitating the synthesis of additional antileprotic medication. At present, it appears that Lamprene (Clofazimine) is the most adequate preparation for the treatment of sulfone and/or other anti-leprotic drug resistant cases, as well as reactive states. The work of Browne and Hogerzeil in 1962, and subsequent studies by ether workers, have demonstrated lamprenes anti-leprotic and anti-inflamatory effects. The drug has also been need successfully in the management of the reactive patient. However, as its most untoward side effect, the drug causes an unsightly darkening of the skin in those areas where the concentration of M. leprae is greatest. Because the literature provides only sparse data on the effect of lamprene on the morphological (MI) and bacteriological (BI) indices of bacteriologically open patients, the authors undertook the following study: Eighteen dapsone resistant patients, two of whom were in lepra, reaction, received a daily dose of 100mg. of lamprene during a period. ranging from 4 to 22 months. Patients were kept under close clinical observation and bacteriological samples were taken at an average of three month intervals from eight different sites on the body, All subjects were in residence at the National Leprosy Hospital of Korea on Sorok island. The study yielded the following results: 1) Within 3 to 8 months after the administration of lamprene, the MI decreas d to the base line in all patients save one. 2) In the short term administered group (less than 10 months), 6 of 1R patients showed a BI increase in inverse proportion to an MI decrease during the initial stage of lamprene administration. However, the BI began to decrease between the 4th and 5th months of treatment. Of the remaining 7 patients, all showed a decrease in both BI and MI. 8) In the long term administered group (more than 10 months), the BI, an indicat- or in the evaluation of long term administration, gradually decreased in 4 of 5 patients. In the remaining patients the BI increased. The authors regard the inverse relationship between the BI and MI as the result of the increment of bacilli secondary to the destruction of M. leprae by lamprene. That groups showed a decrease in both BI and Ml is interpreted as lamprenes biochemical intervention so as to render M. leprae more susceptible to phagocytosis. While. no ready explanation can account for the single case in which the BI increased and the MI also increased, the pos. ibility that there might be a strain of M. leprae resistant to lamprene must be ruled out. thus, given the above results, the authors conclude that lamprene is a valuable antileprotic drug not only for DDF>resistant patients but also for patients in lepra reaction. Moreover, this drug seems to find its best setting in the leprosarium where the untoward side effect of darkened skin does not in any way diminish the patients social relationships.

Multiple neurofibromatosis is known to be a genetic disease with the autosomal dominant inheritance pattern. In clinical practice, however, we can hardly ever find a case in which the autosomal dominant inheritance is demonstrable, because sporadic mutation is believed to cause about 50 % of the observed rnultiple neurofibromatosis cases, and because such patients show reduced fertility. The authors observed a family case in which the typical autosomal dominant inheritance could be demonstrated. Among 17 consanguinities of the 3 generations studied, 12 had developed multiple neurofibrornatosis. The presumed reason for the high incidence of the disease in the family studied is 2 fold: 1) The autosomal dominant gene responsible for the disease is highly penetrable. 2) The mutant gene responsible for the disease, for some unexplained reason, was transmitted from patient No. 1 to a.ll of her offsprings, instead of to only half of her offsprings, as would be expected.

Among the skeletal tuberculous spondylitis is high incidence and curable disease, if early diagnosis and treatment are possible. We reviewed clinical manifestations and radiologic analysis of 30 cases tuberculous spondylitis from May 1983 to Sept. 1986, at Yeungnam medical center, Yeungnam University. The results were follows: 1. The frequent involve sites were thoracolumbar vertebra. 2. The continuous lesion is 86.7% of the all cases. 3. The most common type was intervertebral type, and lytic and sclerotic lesion were same incidence. 4. Paravertebral abscess, kyphosis and disc space narrowing were demonstrated more than 80.0% of the cases. 5. Computed tomography was more accurate diagnostic method rather than conventional plain study to evaluation of extent of lesion, involvement of spinal canal and cord, and size and location of paravertebral abscess. And CT guided abscess drainage procedure was helpful to diagnosis and treatment. 6. Ultrasonography was helpful to differential diagnosis between paravertebral abscess and other solid mass, and useful to follow up study of paravertebral abscess after treatment.

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.
