The air-borne fungi are usually considered to be as non-pathogenic and saprophytic organisms. However, those can be causative factors of certain allergic disease, and produce mycotoxic diseases such as caused by aflatoxin B1,or opportunistic infections, since various kinds of antitumor agents and adrenocorticosteroids have been introduced to therapeutics, and those who are affected some malignant tumors or metabolic anomalous diseases. As the first step toward. understanding and controlling the diseases, the studies on the population of air-borne fungi seem to be necessary. Authors studied the fluctuations of population of air-borne fungi at monthly intervals from June 1974 through May 1975 and at various times of the day at different places in th hospital, and the results obtained were as follows: 1. The identified fungi species and the percentage of colony counts of each species were Hormodendrum sp. (37. 2% ), Penicillium sp. (18. 8% ), Aspergillus sp, (17. 6 % ), Alternaria sp. (6.3 %), Mycelia sterila (2.6 %), Paecilomyces sp. (1.2 %) RhodO torula sp. (1. 1 % ), Oospora, sp. (0, 7 % ), Rhizopus sp. (0. 6 %. ), Geotrichum sp. (0.4%), Monilia sp. (0.4%), Mucor sp. (0.4%), Trichoderma sp. (0.4%.), Trichosporon sp. (0. 1%), Stemphylium sp. (0. 1 % ), Helminthosporium sp. (0. 1%) Gliocladium sp. (0. 1,: ), Saccharomyces sp. (0. 1 % ), Trichothecium sp. (0. 03 % ), and other unknown species(11. 6%) in decreasing order of frequency. 2. The monthly fluctuations of number of cultured colonies of four major airborne fungi (Hormodendrum, Penicillium. Aspergillus, and Alternaria) were 649 in June, 105 in July, 372 in August, 431 in September, 188 in October, 241 in November and 89 in December 1974, and 92 in January, 115 in February, 77 in March, 178 in April and 116 in May 1975. 3. It was suggested that there might be a relationship among the humidity, the temperature and the population of the air-borne fungi because the abrupt drop in July seemed to be related to high level of tbe,humidity (86.8%) and the temyerature (24. 3'C). And since the total number of colonies decreased markedly in December 1974 and Junuary 1975, it seemed to be closely related to cold weather temperature. 4. The number of cultured colonies at various times of the day did not show much fluctuation, except that Aspergillus sp. showed sudden tremendous increase at. one occasion, at 3: 00 P.M. on 15th of June and that gradual increase of Hormodendrum sp. was noted on another occasion from 12: 00 A.M. on 15th of September. 5. With regard to the locations of sampling, such as the operating room, laboratory, ward and out-patient department in the hospital, the difference in the identified. fungi species, the number of colony counts and the relationship with the humidity A the temperature was not evident. Authors reviewed relevant literatures and made discussions also.

Leprosy has two polar types. The one tuberculoid leprosy (TL) is characterized by well preserved cellular immunity with a good prognosia and the other lepromatous leprosy(LL) shows no cellular immunity with a poor prognosis. The preaent study was designed to measure the activity of adenosine deaminase (ADA) in sera and erythrocytes of leprosy patients, as it's activities are known to be decreased in immune deficiency diseases. There were no significant differences in the erythrocyte ADA activities among normal subjects(9. 60+4. 43 units/1012 cells), TL patients (7. 12+2. 51 units/1012 cells) and LL patients(6. 96+0. 81 units/1012 cells), The ADA activities in sera of TL patients(20.15+2. 90 units/L) did not differ from those of normal subjects(20.44+ 2. 07 units/L), but the LL patients(17. 52+3. 30 units/L) showed a slightly lowered activity than those of normal subjects.

Since Epsteins report in 1963, which identified topical corticosteroid therapy as a possible cause of striae formation, many adverse effects resulting from topical steroids therapy has heen observed in dermatological practice. In this study, 365 cases of side-effects with topical steroids in Department of Dermatology, Chonnarn University Hospital from 1972 to 1981 were analyzed, and the results obtained can be summerized as follows; 1. During this pericd, themean average percent of side effects with topical steroids was 0.85 of the yearly total patients and 12 different kinds of side-effects were found to be present in this study. 2. The annual rate of increase of side-effects with topical steroids (2.4%) was higher than that of yearly total patients (0.5%) and the annual frequency of the 12 side-effects was shown in Table 1. 3. The frequency of the 12 side-effects by age group was shown in Table 2. 4. The frequency of the 12 side-effects by season, sex and region was shown in Table 8. 5. The frequency of the 12 side-effects by lesion site was shown in Table 5. 6. T.he mean period of application with topical steroids was 4. 18 months and applied topical steroids were betamethasone-17-valerate(30.4%), fluocortolone (22.7%), hetamethasone dipropionate(12.9%), fluocmolone acetonide (9.0%) and prednisolone(8.8%) respectively. 7. The most frequent topical steroids and period of application causing each side-effects were as follows: betamethaaone-17-valerate for 1 month resulting in Steroid acne, betamethasone-17-valerate for 2 months resulting in Telangiectasia rubeosis et steroidica, triamcinolone acetonide for 1 month resulting in Perioral dermatitis and betarnethasone-17-valerate for 11 months resulting in Atropic striae.

Epithelioid sarcoma is a malignant soft tissue neoplasm with an uncertain histogenesis. We report the imprint cytologic features of epithelioid sarcoma in the left shoulder of a 29-year-old male patient. Imprint cytologic findings showed dissociated and loose aggregates of anaplastic epithelioid cells on the necrotic, bloody, and inflammatory background. Tumor cells were round to polygonal shaped. Tumor cells had vesicular nuclei with abundant cytoplasm. The nuclei were irregular in shape and often eccentrically located. Some tumor cells were oval to spindle shaped. Binucleated and multinucleated cells were found. Intracytoplasmic vacuoles were present. On immunohistochemical stain, the tumor cells were positive for epithelial membrane antigen, vimentin, and CD34.

Cribriform-morular variant of papillary thyroid carcinoma is an unusual and peculiar subtype of papillary thyroid carcinomas. It occurs both sporadically and in association with familial adenomatous polyposis. We report here on two cases of cribriform-morular variant of papillary thyroid carcinoma in a 33-year-old woman and in a 21-year-old woman. On gross examination, both cases were multicentric. The first case showed two well-encapsulated yellow solid masses in the right (2.0 cm) and the left lobes of the thyroid gland (0.5 cm). The second case showed four well-encapsulated gray-white solid lobulating masses and nodules in the right (4.5 and 1.2 cm) and the left lobes (1.1 and 0.8 cm) of the thyroid gland. Microscopically, both cases exhibited an intricate blending of papillary, cribriform, trabecular, spindle, and solid patterns of growth with morular areas. Typical nuclear features of papillary carcinomas were focally seen. Immunohistochemically, the tumor cells were positive for thyroglobulin, thyroid transcription factor-1 (TTF-1), and beta-catenin, but were negative for calcitonin.

PURPOSE: To evaluate the signal characteristics of intracranial hemorrhage, as seen on fluid attenuatedinversion recovery(FLAIR) MR imaging according to various stages, and to compare FLAIR imaging with spin-echo T1-and T2-weighted MR imaging. MATERIALS AND METHODS: We retrospectively evaluated fast FLAIR images along withspin-echo T1- and T2-weighted MR images of 32 lesions in 26 patients (12 males and 14 females, aged 3-84 yrs) withintracranial hemorrhagic lesions. For imaging, a 1.5T unit was used, and the nature of the lesions was found to beas follows : intracranial hemorrhage(n=15) ; tumor(n=9) ; infarction (n=4) ; arteriovenous malformation (n=3) ;and arachnoid cyst with hemorrhage(n=1). On the basis of spin-echo MR imaging, lesions were classified as acute,early subacute, late subacute, early chronic, or late chronic stage. The signal characteristics of intracranialhemorrhage were analysed in accordance with each staging, as seen on MR FLAIR imaging, and compared to the stagingseen on spin-echo T1- and T2-weighted MR imaging. RESULTS: For the 32 hemorrhagic lesions, staging was found to beas follows : acute(n=4) ; early subacute(n=8) ; late subacute(n=11) ; early chronic(n=5) and late chronic(n=1). Inthe remaining three patients with arteriovenous malformation, the stage of the hemorrhage was found to be mixedsubacute and chronic. The signal intensity of hemorrhage, as seen on FLAIR imaging during the acute andearly-subacute stage, was low, and during the late subacute stage it was high ; for T2WI, the findings weresimilar. FLAIR imaging, however, showed that hemorrhage intensity during the early chronic stage was low, and thatof the late chronic stage was very low ; these findings were similar to those of T1WI. CONCLUSION: The signalintensity of intracranial hemorrhage, as seen on FLAIR imaging, was not characteristic ; it was similar to that ofT2WI during the acute and subacute stages, and similar to that of T1WI during the chronic stage. When usedtogether with spin-echo T1- and T2-weighted MR imaging, however, FLAIR imaging may be useful for theclassification of chronic intracranial hemorrhage as either early or late stage.
