We describe herein a case of tick bite ocurring to a 23-year-old man who has a characteristic lesion clinically and histopathologically. The tick(Ixodes sp.) was still attached to the brownish and erythematous, indurated skin of the scrotum. The engorged tick which was carefully removed from the skin with a scalpel was 8.7mm in length and 5. 5 mm in width. Histopathologically, characteristic amorphous eosinophilic materigl is deposited around a round space where the hypostorne of the tick was inserted. Heavy inflammatory cell infiltratton in the mid and lower dermis is composed mainly of neutrophils and eosinophils. A certain area of the lower dermis shows edema and capillary dilatation along with the mixed inflammatory cell infiltration, TVide excision of the indurated lesion including the tick was done. The clinical and hsitopathological findings of the tick bite was discussed.

Lipodystrophia centrifugalis ahdominalis infantilis(LCAI), an atypical form of progressive lipodystrophy, is a diseaee named by Imamura et al in 1971, and reported a few cases in japan. We report a case who has diagnosed as LCAI. The patient ia 5 and half year old boy. He had 2cm by 7cm sized, linear depressed leaion with surrounding erythema on the right inguinal region which was noticed 5 months prior to first diagnosis. There was no family history, no physical abnormality except skin lesion. Cornplete blood cell count, urinalysis, stool examination, liver function test and chest X-ray were within normal limit. Biopsy specimens from the depressed lesion and surrounding erythematous area revealed slight atrophy of the epidermis, a mild lymphocyte infiltration around the vesaels and eccrine glands in the upper part of derrnis, markedly decreased amount of subcutaneous adipoae tissue with mild lymph- ocyte infiltration in depressed area and marked lymphocyte infiltration, intermingled with histiocyte in surrounding erythematous area, but normal amount of adipase tissue.

Respiratory effects of acute coronary embolism were studied in mongrel dogs. Coronary embolism was produced by Agress's method and respirtory effects were observed for two hours. In the experimental group, in which coronary embolism was produced, there were relative decreases in respiratory rate and arterial oxygen saturation along with relative increases in tidal volume, minute ventilation, ventilation equivalent and arteriovenous oxygen difference compared to those in the control group. However, differences in these various measurements between tow groups, those in tidal volume and arterial oxygen saturation, have greatly diminished in two hours. These facts suggest that changes in respiratory rate, minute ventilation, ventilation equivalent and arteriovenous oxygen difference in the experimental group are early but short-lasting responses to acute coronary embolism, whereas changes in tidal volume and arterial oxygen saturation occur early and last longer.

We recently encountered a case of pemphigus vulgaris, which was localized within the oral mucosa and esophagus. The patient was a 62-year-old women, who had had a few recurrent erosions on the oral mucosa for 1 year. Newly developed erythematous erosions on the esophagus appeared 7 days pre previously. Histopathological findings showed suprabasal blisters in the epithelium of the buccal and esophageal mucosa. On direct immunofluorescence, intercellular IgG and C3 bindings were found in the epithelium of the buccal mucosa. Treatment with oral steroids resulted in a remission of the lesions and the other skin lesions were not found for a period of 6 months.

Herpes gestationis(HG) characterized by the development of autoantibodies to the basement membrane is a pruritic bullous dermatosis of pregnancy and the postpartum period. HG is diag nosed on the basis of clinical findings, and a direct or indirect immunofluorescent test including an assaying for the denmonstration of IgG autoantibody in the serum. We report a case of herpes gestationis in Korea which showed a typical clinical and histopathologic findings accuring in a 30-year old primiparous patient. We could confirm the diagnosis in this case by in vitro C3 staining, and immunoblot analysis which revealed the presence of antibodies in her sertim against 180kD antigen of epidermal protein.

BACKGROUND: The elderly ex-smokers are not free from the effect of previously exposed smoking, and have a tendency to participate in health promoting behavior eagerly. This study was designed to evaluate factors that affect pulmonary function in the elderly ex-smokers. METHODS: The ex-smokers with normal chest radiological findings who visited Seoul National University Hospital Health Promotion Center were analyzed. The effect of various factors including age, height, smoking amount, and duration of smoking cessation on pulmonary function indices were analyzed with bivariate correlation analysis. Multiple regression analysis was performed using factors indentified significant in bivariate correlation tests. RESULTS: Multiple regression analyses were done for the all age group and the elderly group. Factors significantly affecting Forced vital capacity(FVC) were height,age and duration of smoking cessation for both grroups. Smoking amount was not significant. Forced expiratory volume in 1 second(FEV1) was significantly influenced by height, age, duration of smoking cessation, and smoking amount for both group. In the all age group, peak expiratory flow(PEF) was siginificantly influenced by age, regular exercise, and duration of smoking cessation. In the elderly group, PEF was significantly affected by height, age, regular exercise, and duration of smoking cessation. The factors significantly affectiong FEV1/FVC were age, smoking amount in the all age group, and regular exercise, smoking amount in the elderly group. CONCLUSION: Smoking amount was a significant factor decreasing FEV1 in the elderly ex-smoker. Duration of smoking cessation was significant in normalization of pulmonary function indices in both the all age group and the elderly group. It is inferred that smoking cessation is beneficial in reversing the adver sely affected pulmonary function indices even in the elderly.

Brunner's gland adenoma(or Brunneroma) is clinically relevant tumor-like lesion of the duodenum which is composed of submucosal Brunner's gland tissue. Since the first case by autopsy was described by Cruveihier in l935, there have been less than 190 reports in the world literature, Brunner's gland adenoma is an extremely rare entity that accounts for only 10.6% of benign duodenal tumors, which are themselves relatively rare representing 0.008% of all surgical and autopsy specimens. The clinical manifestation of this tumor are non-specific gastrointestinal complaints, such as bloating or epigastric pain, and tumor often gives rise to melena or obstruction, It is postulated that this tumor are hamartomas rather than true neoplasm. However, they undergo rarely malignant transformation. We report on a case of a large pedunculated Brunner's gland adenoma, which was successfully polypectomized.
