Recently, we have experienced case of juxtapapillary retinal angioma. This patient was a 32-year-old Korean woman who visited our hospital because of blurred vision in her left eye for about 20 days. At the time of examination, the visual acuity of this eye was 0.3. Ophthalmoscopic examination revealed a sherical, highly vascularized tumor at the temporal margin of the optic papilla and peripapillary retinal exudates. This case was presented with a brief review of the literature.

We experiened a case of electrical retinopathy, following industrial electrocution. The patient complained of acute visual loss due to corneal edema, anterior chamber reaction, lens opacities, vitrons reaction, retinopathy and secondary glaucoma. The visual acuity was improved during hospital day and short term after discharge period, but worsened,eventually by progressive anterior chamber and posterior segment pathologies, that is lens opacities and optic atrophy etc, We Performed several ocular examinations, including visual field, fundus phetography and fluorescein angiography during admission and follow-up pericd. A brief review of the literature is described.

During development of central nervous system, cell proliferation, cell migration, cell differentiation and cell death are required. It has been reported that a number of cells are dying during development in the mammalian retinae examined so far, but the pattern of cell death has not been clarified yet. In addition. little has been studied on cell proliferation after birth. This study was conducted to identify histogenesis, cell death and cell proliferation in the retinae of the developing rats by light and electron microscopic methods as well as by immunohistochemical method using anti-proliferating cell nuclear antigen [PCNA] antiserum. The results were as follows : 1. In the developing rat, from postnatal 0 through 7 days, retina consisted of ganglion cell layer, inner plexiform layer and neuroblast layer. Neuroblast layer could be subdivided into three sublaminae : sublamina a, sublamina b and sublamina p, from postnatal 3 through 7 days. 2. From postnatal 10 days, retina consisted of ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer and outer nuclear layer. 3. Cells undergoing degeneration were observed from postnatal 0 to 13 days, and patterns of cell death were apoptosis, cytoplasmic degeneration and autophagic degeneration. 4. PCNA-immunoreactivity was seen in the cells located in sublaminae b and p of the neuroblast layer at postnatal 0 and 1 days. From postnatal 3 days PCNA immunoreactivity decreased. At 7-day-old rat, PCNA-Immunoreactive cells scattered in the distal part of sublamina p of the neuroblast layer.No immunoreactivity was observed from postnatal 10 days. These results demonstrate that retinal cell proliferation ends at postnatal 7 days, and histogenesis of retina is completed at postnatal 10 days, and superfluous cells during retinal development are eliminated by apoptosis, cytoplasmic degeneration and autophagic degeneration.

BACKGROUND: It is well known that the cutaneous tuberculosis especially skin tuberculids is difficult to detect early and make a confirm diagnosis because the organism is seldom detected in a lesion by conventional methods such as AFB stain and culture. The polymerase chain reaction is a very powerful molecular biological tool in diagnosing infectious, neoplastic and genetic diseases. It has the merit of employing various samples, and to improving sensitivity by the modification of PCR techniques. Usage of the routinely formalin-fixed paraffin-embedded tissue as a sample for PCR is very useful in clinical examination, however the sensitivity and specificity have been known to be decreased. OBJECTIVE: To evaluate the efficacy of the nested-PCR in the diagnosis of different types of cutaneous tuberculosis, we tried to detect the DNA of Mycobacterium tuberculosis from routinely formalin-fixed paraffin-embedded tissue. METHODS: The various cutaneous tuberculosis and infectious granulomatous disease were retrospecitively selected by the findings of clinical, histopathological and bacterial culture. There were 9 cases of lupus vulgaris, 4 tuberculosis verrucosa cutis, 2 papulonecrotic tuberculid, 2 erythema induratum and 4 lupus miliaris disseminatus faciei. To amplify the 123bp DNA fragment of a repeated insertion sequence IS6110, two pairs of primers composing outside and inside primers were applied. RESULTS: The positive band was found in 10(91% ) of lupus vulgaris, 3 of tuberculosis verrucosa cutis, 1 papulonecrotic tuberculid and 1 erythema induratum. Four of the LMDF and 5 of the infectious granulomatous diseases were negative. CONCLUSION: The nested-PCR using routinely formalin-fixed paraffin-embedded tissue is a useful diagnostic tool if combined with the result of other clinical data. Also it may provide further insight into pathogenesis of skin tuberculids and the differential diagnosis of granulomatous skin diseases.

It is a rare occurrence that cervical cancer and aplastic anemia are combined, but eight cases were reported since Fujiu's report in 1968. There has been no one who have reported the case of like this in Korea. And so, we report this case for the support of idea of treatment in aplastic anemia patient combined with cervical cancer. The knowledges required are early detection of malignancy and the individualization of the treatment according to the status of the patient, the bone marrow function saving procedure and the prevention of the patient from death involved with bleeding and sepsis induced by infection.

OBJECTIVE: To determine whether cyclooxygenase (COX)-1 and COX-2 are expressed differentially during the whole gestational period in the pregnant human uterine cervix and if they are involved in the process of labor. METHODS: Nine patients were matched for obstetrical history and maternal age were divided into an abortion group who aborted between 13 and 16 weeks(n=3), a preterm group who delivered between 20 and 37 weeks(n=3), and a term group who delivered between 37 and 42 weeks of gestation(n=3). Immediately after vaginal delivery cervical biopsy samples were obtained and immunohistochemically stained for COX-1 and COX-2 and the degree of staining was evaluated by H-scoring system. RESULTS: Expression of COX-1 and COX-2 was found in epithelial and stromal cells of uterine cervical tissues of preterm and term group. The immunohistochemical expression of COX-1 and COX-2 was strongest in the term group compared to the preterm group in stromal cells(HSCORE : 2.0 vs. 4.0 ; 2.0 vs. 3.0), and in epithelial cells(HSCORE : 1.0 vs. 3.0 ; 1.0 vs. 3.0). CONCLUSION: Although small amount of the groups were investigated, in the pregnant human uterine cervix, COX-1 and COX-2 are found to be expressed, and both shows the strongest expression in term cervical tissue. It is suggested that the uterine cervix, under the control of prostaglandins, is actively involved in the process of labor, and it is thought that the role of COX-1 and COX-2 is more important in parturition process with advancing gestational age.
