Prevalence of sparganum in the frog (Rana nigromaculata) was surveyed in Dae-jeon city and in suburbs of the city, Chungnam Do. 39 (3.9 per cent) out of 1,011 frogs were infected with the worm, and the highest prevalence rate of sparganum was found the frogs from Shintanjin area(11.3 per cent). Infection rates of sparganum were observed due to the body weight and sex of frogs. The highest infection rate of frogs, the body weight of 50 gms or more, showed 30.3 per cent(female: 41.7 per cent, male: none), on the other hand, no worm was found in young frogs(less than 10 gms). Distribution of sparganum in the frogs was recorded and 82.6 per cent of worms were distributed in the femoral intermuscular connective tissues of the hind legs. Among those infected frogs, number of worm burden was one to five worms, and 53.3 per cent of frogs were infected by only one worm.

Cutaneous leishmaniasis is a self-limited infection of the skin caused by Leishmania tropica, a protozoan parasite transmitted by Phlebotomus sandfly. This disease is endemic in tropical and subtropical zone, but recently many cases of cutaneous leishmaniasis were reported in Korean among the peoples who had been worked in the Middle East. We experienced five cases of cutaneous leishmaniasis developed in Korean who had been worked in Saudi Arabia and Jordan. Skin lesions of various sized, central ulcerated and marginal elevated, with serosanguinous discharge and some crust were scattered on exposed area, especially both extremities. Histopathologic findings showed hyperkeratosis, acanthosis, pseudoepitheliomatous hyperplasia, dermal infiltration of histiocytes, lymphocytes, plasma cells and neutrophils, and numerous Leishman-Donovan bodies in and around histiocytes. About 1-4 months treatment with trimethoprim-sulfamethoxazole and metronidazole, two cases were healed with hyperpigmented scar and two cases were improved but one case was not responded.

We retrospectively studied 53 cases of thymic tumors diagnosed after thymectomy to clearfied the pathologic difference of thymic tumor associated with myasthenia gravis and without myasthenia gravis. Among them, there are 23 cases with myasthenia gravis; 19 among 36 thymomas(52.8%), 3 of 4 thymolipoma (75%) and 1 squamous cell carcinoma. Lymphoma and teratoma are not associated with myasthenia gravis. There is no significant difference in the prevalence of myasthenia gravis between types of the old traditional classification of thymoma. But according to the new Muller-Hermelink classification, about two-thirds of myasthenia gravis have the thymoma with cortical cell origin. The prevalence of myasthenia gavis were relatively low in the patients with thymoma of medullary or mixed type. The frequent association of myasthenia gravis was suggesting that the thymolipoma might be a variant of thymoma, cortical type.

The Venereal Disease Research Laboratory microflocculation (VDRL) test, especially the quantitative test is well standardized, simple, rapid and, at present, the most widely used non-treponernal test in serodiagnosis and follow up sturly of syphilis. However, the UDRL test result could be influenced by room ternperature, especially in summer and winter in Korea in the abscence of proper air-conditioning and heating. This study was undertaken to evaluate the effect of room temperature on the VDRL test result and to determine the critical temperatures which alter the test result. Eighty six VDRL-reactive serum samples collected at the Soonchunhyang Medical College Hospital and the V.D. Clinic of the Chung-Ku Public Health Center in Seoul during the 7 months periods from September 1982 to March 1983 were used. The results obtained were as follows: The change in the VDRL titer was not obscrved at room temperature of between 18 C and 32 C 2. The VDRL titer became weakly reactive on the same titer or lowered to half titer at room temperature of below 18C. R. The VDRL titer increased two fold at room temperature of above 32C.(countinue..)

Herpes Gestationis is a rare polymorphous, vesiculobullous disease of pregnancy and puerperium. It is characterized by rapidly progressive skin eruption heraled initially by severe generalized pruritus. Erythematous papules and urticaria like plaques rapidly appear followed by grouped, tense, vesiculobullous eruptions. A 23 year-old pregnant woman was admitted to our departrnent of dermatology hecause of erythematous patches with pruritic vesiculobullous and pustular eruption on the whole body since third week of conception, Biopsy specimen of bullous skin lesion showed spongiosis of epidermal cells, mild necrosis of basal cells, subepidermal bulla, edema, of papillary derrnis and perivascular infiltration of inflammatory cells. Ultrastructural findings showed mild necrosis of basal cells, bulla above or below basement membrane zone and partial separation of basal larnina. Direct immunofluorescences of bullous lesion and normal appearing skin demonstrated deposition of IgG in linear pattern along basement rnembra,ne zone. After treatment with systemic corticosteroid and antihistamin, the lesions were cleared, leaving residual hyperpigmentation, and she delivered normal female baby.

It is the purpose of this study to determine the benificial effect of treatment with methylprednisolone on the enhancement of Na+, K+-ATPase activity and the increased ATP level during the 4 hours after a 400gm-cm injury to the spinal cord of cat. These results demonstrate that high dose (30mg/kg) of methylprednisolone can benificially enhance the activity of neuronal Na+, K+-ATPase during the first 4 hour after spinal cord injury. But the enhancement of this enzyme activity is not significantly increased with mega dose (60mg/kg) of methylprednisolone. Tissue level of ATP in the high dose-treated cat at 1 hour after trauma was significantly elevated, but those in high dose-treated cat at 4 hour and the 1 and 4 hours with mega dose-treated groups were not significantly increased. The protective effects of methylprednisolone in experimental spinal cord trauma are the enhancement of Na+, K+-ATPase, inhibition of the free-radical reaction and the lipid peroxidation, the increment of neuronal activity and ATP utilization. High dose(30mg/kg) of methylprednisolone is required in order to produce the acute effect in the early phase experimental spinal cord injury.
