Eighty-two strains of Escherichia coli isolated from urine specimens in Pusan University Hospital, were serotyped and analyzed for plasmid DNA profiles, PFGE profiles, MRHA of human blood cells, HEp-2 cell adherence ability and reactivity to bfpA, LT, STh and STp DNA probes. The following results were obtained. Fifty-three of the eighty-two strains belonged to thirteen different 0 serotypes, twenty-nine strains could not be typed with the antisera used. Thirty strains (43.9%) were hemolysin producer. MRHA is present on twenty-nine strains (35.37%) of eighty-two strains. MRHA positive strains carry a plasmid of 60MDa, a putative factor involved in adherence. This plasmid might be specific for MRHA positive strains. MRHA positive strains were observed in serotype 01, 018, 055, 086a, 0119, 0126, and 0142. Twenty-six strains of E. coli showed three patterns of adherence to HEp-2 cells namely, localized, diffuse, and aggregative adhesion. Twenty-two strains hybridized with the bfpA probe, while all eighty-two strains did not hybridize with the probes, LT, STh, STp. The restriction fragment patterns of chromosomal DNA digested with AotI analysed by PFGE of hemolysin-producing E. coli ten strains were compared with eight different types. Three of E. coli serotype 01, 08 and 0126 showed the same chromosomal DNA fragment patterns.

BACKGROUND: The reproducibility in grading a cervical intraepithelial neoplasia (CIN) are not perfect. The aim of this study was to assess the value of the immunohistochemical expression of p63 and the other biomarkers for grading a CIN (dysplasia and in situ carcinoma), and diagnosing invasive carcinomas. METHODS: Sixty six cervical specimens were immunostained with the monoclonal antibodies against p63, Ki-67, p27Kip1, and p53 to determine the localization. RESULTS: The p63 positive cells are well linked with squamous cell maturation and the degree of dysplasia. In mild dysplasia, the p63 positive cells were localized to the basal and parabasal cells, which gradually extended into the middle and upper layers in moderate and severe dysplasia. p63 expression was strong in immature squamous epithelium and invasive squamous cells, but was constantly absent in an adenocarcinoma. The Ki-67 positive cells were scattered from the parabasal cells to the superficial cells in accordance with the degree of dysplasia. p27Kip1 expression was noted in the intermediate cells in the normal cervix. In CIN, the p27Kip1 positive nuclei tended to extend to the basal cells, but it showed no diagnostic consistency in an invasive carcinoma. p53 expression was also variable. CONCLUSION: p63 is a useful diagnostic adjunct for grading CIN as well as for detecting microinvasion and squamous differentiation in invasive carcinoma. However, immunohistochemical expressions for the p27Kip1 and p53 have no correlation with the grade of CIN and squamous cell carcinoma.

5.Studies on the Cellular Transfer of Autoimmune Uveitis.
Journal of the Korean Ophthalmological Society 1976;17(3):259-264
After the immunization of pigmented guinea pigs with bovine rod outer segments in complete Freund's adjuvant, the regional lymph nodes were excised, teased and sedimented by centrifugation. These fresh lymphocytes were injected intravitreally (a single injection of 10 X 10 cells in 50 micro l) in 18 eyes. The involvement of the ciliary body and the choroid with polymorphonuclear leucoytes and later with round cells was noted in 16 eyes. Destructions of the visual cells of the retina were demonstrated in 8 eyes. When the fresh lymphocytes were injected subconjunctivally (50 X 10 cells in 30 micro l) four times. four of the 8 eyes showed slight infiltrations of the ciliary body and the choroid with round cells. No retinal lesion was found. Following repeated freezing and thawing of the lymphocytes. transfer experiments wereperformed with the nonviable cells and their extracts respectively. In 8 eyes injected intravitreally with nonviable cells. 2 eyes showed the infiltration of the uvea with round cells, whereas. of 6 eyes injected subconjunctivally, only one eye showed such changes. The extracts of lymphocytes were injected intravitreally in 8 eyes of which 5 eyes demon-strated moderate degree of infiltration of the uvea. Of 2 eyes injected subconjunctivally, 2 eyes. showed slight histological changes. As control experiments, lymphocytes taken from animals immunized. only with the adjuvant were treated as before and transferred to normal animals. Only one eye of 3 eyes received single intravitreal injection of fresh cells showed slight degree of infiltration of the uvea. Thus it can be concluded that the experimental autoimmune uveitis in guinea pigs could be transferred to normal animals by the transfer of non-viable lymphocytes and especially by their extracts.

The authors presented a case of malignant melanoma of the choroid which had been unsuspected clinically. The patient, 38-year-old female, came to Korea General Hospital on Dec. 5-1973 because of blind painful eye and white pupil in the left side. And she was told at local clinic that she had retinal detachment in that eye about 3 years ago. We thought of this case as secondary glaucoma due to swollen lens behind at first. Therefore cryoextraction of the lens was performed for relieving the ocular pain, on Dec. 5-1973. Increased I.O.P., however, had been persisted and ocular pain had not been improved until the patient entered this hospital again on Jan. 25-1974. Enucleation was performed and choroidal malignant melanoma (spindle type) was proven by histopathological study. The patient was instructive to us that we should always remind the possibilities of intraocular tumor behind the opaque media, in cases of unilateral glaucomatous blind eye with shallow anterior chamber.

Elastofibroma is a rare entity of slowly-growing, solid, ill-defined fibroblastic mass occurring almost exclusively in elderly persons and arising mainly from the connective tissue between the lower portion of the scapula and the chest wall. This entity has been considered to be a degenerative pseudo-neoplastic process caused by mechanical friction. We report an additional case of elastofibroma removed from the subscapular region of a 58-year-old woman. Microscopically the tumor was made up of a mixture of swollen eosinophilic collagen and elastic fibers occasionally associated with fibroblasts and mature fat cells. The elastic fibers showed a degenerated beaded appearance or were fragmented into small globules or droplets in a linear pattern.

10.A Case of Glaucomatocyclitic Crises.
Journal of the Korean Ophthalmological Society 1970;11(4):67-70
A case, 25-year-old male student who is thought to have been suffered from glaucomatocyclitic crises in the left eye, is presented. Authors have followed this patient for about one and a half years. During the time, 10 times of recurrent unilateral attacks of ocular hypertension have been noted with assoicated mild iridocyclitis. An attempt was made to evaluate the clinical pictures and review the literatures.
