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.

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.

In order to investigate the effects of diathermy and cryosurgery on the scleral shrinkage, nonperforating surface diathermy and cryocautery were applied in rabbits eyes. The premarked scleral segments were measured by corneal microscope with micrometer, and the resultant elevation of the intraocular pressures was pressures was measured by Schiotz tonometer. In the eyes treated by 10 diathermy in 5 X 3mm area, average 20.1% of scleral shrinkage was observed. There was no significant difference between shrinkages in the meridional and latitudinal directions. In the eyes treated by cryopencil no significant changes were found. Diathermy applications in 3 X 10mm area in the sclera induced 36.9% increase in the intraocular pressure which lasted about 9 minutes. On the other hand, cryoapplication did not produce such an elevation in ocular tension.

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.

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.
