Fifteen hundred seventy-one leprosy patients registered in the leprosy Mission Hospital from Mar. 1957 to Sep. 1980 were investigated for dapsone resistance by clinical and bacteriological aspects. The results are as follows: There were 29 suspected dapsone-resistant cases out of a total 1571 registered leprosy patients (1. 85%), 26 of 650 of lepromatous type(4. 00%), and 3 of 164 of borderline type (l. 83%). In 1969, we observed the first case if suspected dapsone-resistant leprosy. Since then, suspected dapsone-resistant cases increased and we observed as many as 8 cases in 1977. But frequency of cases has decreased since 1978. (countinued..)

Tuberous sclerosis is a complex neurocutaneous disease inherited as an autosomal dominant pattern, which is characterized by facial angio-fibroma, mental retardation and seizures. Many cases have been reported in the literatures, but familial cases are relatively rare. We present 9 cases of tuberous sclerois occuring througb 3 generations, which are 3 cases of angiofibroma, mental retardation and seizures, 2 cases of facial angiofibroma and seizures, 1 case of mental retardation and seizures and 3 cases who showed facial angiofibroma only. Two brothers in this family reveald icthyosis vulgaris without tuberous sclerosis.

Dermatitis herpetiformis occurs rarely in childhood and certain features of the disease in children differ from its manifestation in adults. The eruptions are commonly bullous, show little predilection for the typical regional pattern of the adults, may be nonpruritic, have a shorter course, and often are resistant to the usual therapy. A review of literature shows that in patients over 50 years of age or older the tendency is to manifecst predominantly, although not as strikingly for children, a vesicobullous type of dermatitis herpetiformis with large bullae, varying 1 to 5cm or more in diameter. The authors present two cases of bullous dermatitis herpetiformis confirmed by histology; the first case is a 5 year-old boy who has tense bullae, pustules, and pigmentations on the inguinal region, lower abdomen, buttocks, face, and extensor surfaces of the extremities of 1 yars duration; the second case is a 44 year old housewife who has eruptions of vesicles, bullae, and erosion on the buttccks, back, abdomen, ext;remities, oral cavity, and vulva of 15 days' duration. The authors reviewed the relevant literature and discussed the clinicaI feat ures of both cases thoroughly.

A xanthoma is a localized collection of tissue histiocytes containing lipid and is usually associated with hyperlipidemia. Tendinous and tuberous xanthomatosis have been found in association with familial hypercholesterolemia, Type III hyperlipidemia, beta-sitosterolemia and cerebrotendinous xanthomatosis. Tendinous and tuberous xanthomatosis without hyperlipidemia have been reported very rarely. Especially tendinous xanthomatosis without hyperlipidemia have not been reported at all in korea. We are reporting a patient with tendinous and tuberous xanthomatosis accompanied by normal plasma lipids

Mammary carcinoma was induced in rats by itravenous injection of N-methy-N-Nitrosourea. Microangiography was perfromed to evaluate the microvascular alterations in mammary carcinoma after irradiation. The tumors were givena single dose of 1.400 rads using Co-60 telethrapy unit with field size of 4 x 4 cm at 40 cm SSD. The dose ratewas 147.5 rads per minute. Microangiography was performed prior to irradiation and at one, two, and four weeksfollowing irradiation. The results are as follows: 1. Before irradiation, mammary carcinoma in rats tended to formlobules and the basic vasculature consisted of peripheral vascular pattern with central penetrating vessels. Theperipheral vascular pattern was always richer than that of the center. Irregular and tortuous vessles stretchedfrom the periphery into the center of lobule. 2. One week following irradiation, an increase in the number ofsmaller, tortuous vessels and decreased intervasular distance were obseved in the central portion of each lobule.This finding seems to be due to an improved filling of some previously existing but unfilled vessels. This maylead to improved metabolic changes and reoxygenation. 3. Later's changes of microvasculature after irradiation aretortuosity, irregularity, narrowing, abrupt tapering, fragmentation, and extravasation. These findings progressedafter a lapse of time. 4. The results can be considered as the microangiographic demonstration of the fact that reoxygenation after irradiation is mainly due to dilatation of the collapsed tumor vessels.

Alteration in the hormone level associated with menstrual cycle influences the interaction between the urethra and bladder as well as detrusor function, maybe due to the common embryological origin of lower female genital and urinary tract. We tried to investigate the effect of the menstrual cycle on cystometric diagnosis through this retrospective study. 60 women with regular menstruation were enrolled in this study. The study groups were divided into 2 groups, Group I was women whose symptoms were not influenced by the menstrual cycle, Group II was women whose symptoms were adversely affected premenstrually. The majority of normal cystometric diagnosis were made in the luteal phase (Group I: 42.9% vs 4.4%, p<0.05; Group II: 50.0% vs 22.2%, p<0.05). But diagnosis of genuine stress incontinence, detrusor instability, mixed genuine stress incontinence and detrusor instability were frequently made in the follicular phase of mentruation. Normal cystometric diagnosis in the group II were more commom than the group II ( 36.8% vs 19.7%, p<0.05 ). The results of this study reveal that the timing of cystometric evaluation may influence the the detection of a positive diagnosis. In patients whose symptom are influenced by their menstrual cycle, the luteal phase may not be the correct time to make an accurate diagnosis.

The Naka-Rushton equation of the form, R = R(max) I(n)/(I(n)+K(n)), has been used to describe the b-wave luminance-response function of the scotopic electroretinogram. Rmax is the asymptotic value of the b-wave amplitude as a function of stimulus luminance I, K is the luminance that produces a b-wave amplitude that is one-half R(max), and n is a dimensionless constant that controls the slope of the function. These three parameters are often used in research laboratories, since it can show selective changes in each parameter. The present study describes these parameters (R(max) = 354 +/- 28 uV, n = 0.80 +/- 0.06, log K = -2.26 +/- 0.15 log cd. sec/m2) and the values obtained from the derivative analysis of Naka-Rushton equation (Anastasi et al) in 20 normal pigmented rabbit eyes. However, Naka-Rushton equation accurately describes the function only at low to moderate flash luminances. At high flash luminances, a second amplitude increase appears in the function.

The Naka-Rushton equation, R=R(max) I(n)/(I(n)+K(n)), has been used to describe the luminance-response function of the scotopic electroretinogram. R(max) is the asymptotic value of the b-wave amplitude as a function of stimulus luminance, K is the intensity that produces a b-wave amplitude that is one-half R(max) and n is a dimensionless contant that controls the slope of the function and represents the degree of homogeneity of retinal sensitivity. These three parameters are often used in experimental laboratories, since it can show selective changes in each parameter. The present study describes and compares the parameters of Naka-Rushton equation obtained by using ganzfeld stimuli(R(max)=363+/-32 uv, n=0.86+/-0.06, log K=-2.39+/-0.19 log cd.sec/m2) and direct flash stimuli(R(max)=354+/-28 uv, n=0.80+/-0.06, log K=-2.26+/-0.15 log cd.sec/m2) in 20 eyes of the normal pigmented rabbits respectively. The n values were significantly increased by the ganzfeld light stimuli than by the direct flash stimuli(p<0.05).
