BACKGROUND: Ethyl crbmate(EC) has been identified at low microgram quantities in various fermented beverages, destiled products and tobacco smoke. EC has long been known as a carcinogen. Oxidation of the ethyl group of EC is followed by dehydration to yield the carcinogen vinyl carbamate (VC). This is further oxidized to vinyl carbamate epoxide(VCO). VC and VCO proved to be much more carcirogenic than EC. OBJECT: The objective of this study is to compare the potency of carcinogenic ability and histologic changes in skin tumors induced by EC, VC, or VCO. METHODS: In this exeriment, the tumor induction was performed by painting the mouse skin once a week for five weeks with EC, VC and VCO solution, and then 12-0-tetradecanoyl-phorbol-13-acetate(TP2) was treated in the same manner twice a week for 35 weeks. We biopsied the skin at B 0, 15, 25, 30 and 35 weeks and stained the specimens with hematoxylineosin. RESULTS: The time period for the first appearance of papilloma was 6 weeks in the VC-TPA and VCO-TPA group, but, 15 weeks in the EC TPA group. The average number of papilloma showed a statistically sign.ficant difference after 15 weeks between the EC-TPA, VC-TPA and VCO-TPA group. The occurrence of keratoacanthoma and squamous cell carcinoma was 16 and 21 weeks respectively. Histologic changes, such as epidermal layers, pseudohorncysts, degree of hyperkeratosis, hypergranulosis, dysplasia and dyskeratotic cells were more prominent in the papil loma than in the non-papilloma lesion. Dermal changes disclosed similiar findings, that is, increased dermal thicknes, proliferation of vessels and hair follicles, and fibrosis of the dermis. Squamous cell carcinomis and keratoacanthomas were produced only in the VCO-TPA group. CONCLUSION: From the above results it is concluded that VC and VCO have a more potent carcinogenic potential than EC. Various skin tumors, such as papilloma, keratoacanthoma or squamous cell carcinoma were prorduced by the above carcinogens.

Pneumocystis carinii is a pulmonary pathogen of immunocompromised humans or other mammals. Its infection results from activation of organisms involved in latent infection or from new infection through the air. Almost all children are known to be infected within 2 to 4 years of birth, though prenatal transplacental transmission has not yet been demonstrated. In this study we observed experimental P. carinii infection in neonatal rats, thus investigating the possibility of transplacental vertical transmission by Diff-Quik staining of the lung impression smears and in-situ hybridization for lung sections. The positive rate of P. carinii infection in immunosuppressed maternal rats was 100%, but that in normal maternal rats was 0%. Cystic forms of P. carinii were observed in three of six 1-week old neonatal rats born of heavily infected mothers, but none of them was positive by in-situ hybridization. Five weeks after birth, cystic forms were detected in four neonatal rats. In the lobes of the lungs, no predilection site of P. carinii was recognized. Counts of cystic forms on smears and the reactivity of in-situ hybridization in the lungs of neonatal rats were significantly lower than in maternal rats. The present findings suggest that P. carinii is rarely transmitted through the placenta and proliferates less successfully in the lungs of neonatal rats than in mothers.

Tegafur [1-(tetrahydro-2-furyl)-5-fluorouracil], the prodrug of 5-fluorouracil, is an anticancer agent. Several cutaneous reactions have been reported following systemic 5-fluorouracil for the treatment of malignancies. We report a patient with marked inflammation of the actinic keratosis following the use of tegafur for stomach carcinoma. The side-effect with 5-fluorouracil was beneficial as most actinic keratosis cleared following the inflammatory reaction. Dermatologists and oncologists should be aware of this potential side-effect, not only because it may become more prevalent but, most importantly, because it is not an allergic reaction to 5-fluorouracil but a dose-dependent response, and the chemotherapy may be continued in most patients.

PURPOSE: To identify clinical characteristics and preoperative factors that influence the surgical results of an intermittent exotropia patient who underwent lateral rectus recession after the age of 10 years. METHODS: A retrospective study was performed based on the medical records of 45 patients who underwent unilateral lateral rectus recession or bilateral lateral rectus recession for intermittent exotropia after the age of 10 years and who had undergone at least three months of postoperative follow-up. The authors investigated the clinical characteristics and factors associated with surgical success according to gender, age at surgery, fusion ability, preoperative angle of deviation, preoperative difference between near and far angles of deviation, vertical deviation, spherical equivalent of refractive error, Randot stereo test and postoperative angle of deviation at one week, one month, and three months. The postoperative deviation change according to the time between groups who underwent surgery before and after 10 years of age for intermittent exotropia was also compared. RESULTS: Surgical success was defined as a final deviation of less than 10 prism diopters. Patients without vertical deviation had a better surgical outcome than did patients with vertical deviation (p=0.022). There was no significant difference in the postoperative deviation changes between groups who underwent surgery for intermittent exotropia before 10 years and after 10 years of age. CONCLUSIONS: Among the many preoperative influencing factors, vertical deviation showed a significant difference in postoperative improvement after intermittent exotropia surgery undergone after the age of 10 years. There was no difference in the aspects of surgical success between surgeries for intermittent exotropia before and after the age of 10 years.

We investigated the clinical aspect and immunologic parameters of childhood and adult vitiligo in our clinics and made a comparative study. The childhood vitiligo showed the following results : similar incidence of clinical patterns with adults except for the lower incidence of the acrofacial type than in adults ; less involvement in the extent of lesion of disease than in adults ; higher incidence of family history than with adults ; of the precipitating factors, trauma is the main one whereas emotional stress is for adults ; higher association with halo nevi than adults ; and lower incidence of serum autoantibodies than adults. We have ascertained that childhood vitiligo is a distinct subset of vitiligo, showing the above features which will be studied in more patients in a long term follow-up clinical study.

The recent hypothesis about the pathophysiology of schizophrenia has been centered mainly on two theories, i.e. dopamine hypothesis and serotonin hypothesis. We investigate the correlations between plasma metabolite concentrations and clinical symptoms in schizophrenic patients. The purpose of our study was to examine whether the plasma levels of HVA(homovanillic acid) and 5-HIAA(hydroxyindoleacetic acid) are significantly different in schizophrenics, compared to normal controls. And, with the intention of clarifying the interaction between dopaminergic system and serotoninergic system, the ratio of HVA/5-HIAA also was measured. The second purpose was whether the basal(pre-treatment) levels of these metabolites show the correlation with clinical symptoms. Finally, third purpose was whether basal HVA and 5-HIAA levels can be held as a predictor of treatment response. We used scale for the Assessment of Positive Symptoms(SAPS) and Scale for the Assessment of Negative Symptoms(SANS) as the clinical symptom rating scales. Our results were as followed, 1) only the level of basal plasma HVA was significantly differ in schizophrenics. 5-HIAA and HVA/5-HIAA were not. 2) basal HVA showed significant correlation with SAPS score, especially delusion subscale. 3) the higher was the basal HVA level, the more improvement in clinical symptoms was observed. The basal 5-HIAA level and the HVA/5-HIAA ratio did not show any significant findings. These results support the dopamine hypothesis of schizophrenia, but fail to examine on the possible involvement of serotonin in schizophrenia.
