Phthisis bulbi, resulting from repeated ocular inflammation and infection or ocular trauma, causes various degeneration of ocular tissue as well as changes in ocular external shape. It shows the impression of scleral thickening with calcification of ocular tissue and an unusual ossification as well. Having observed 31-year-old patients of phthisis bulbi and band keratopathy caused by repeated operation after ocular trauma years ago, we extracted the tan brown colored shell-like firm tissue in posterior segment and report sclerotic impression of some of ocular tissue and histopathologic finding of the typical ossificationof ocular tissue during the course evisceration.

2.The Effect of Retinoic Acid on Experimentally-Induced Proliferative Vitreoretinopathy in the Rabbit.
Journal of the Korean Ophthalmological Society 1997;38(10):1755-1763
The proliferative vitreoretinopathy was a complication followed by operation of rhegmatogenous retinal detachment. It was the mot, comon cause of a failure of retinal detachment surgery. It was characterized by the growth of cellular fibrous membrance in detached both retinal side and vitreous and also developed by giant retinal dialysis, posterior segmental trauma, excessive cryotherapy, endophthalmitis, retianl vascular disease. In order to prevent and treat of proliferative vitreoretinopathy, various methods of operation and drugs have been researched. We executed the experiment using the rabbit to observe the effect of retinoic acid that is known by inhibition of migration and proliferation of retinal pigment epithelial cell and fibroblast in vitro. With 121 eyes of rabbit, we induced the proliferative vitreoretinopathy by injecting of human retinal pigment epithelial cell, human fibroblast, and rabbit fibroblast into eyeball of rabbits. The extent of proliferative vitreoretinopathy was compaired by injecting those cells with the group that was injected by retinoic acid and control. The result was that in those cell groups, the extent of proliferative vitreoretinopathy was significantly higher in the rabbit fibroblast group than the other two groups(P<0.05). And in the groups that were injected retinoic acid, when subconjuctivaly injected(0.3mg/0.3ml), proliferative vitreoretinopathy was effectively suppressed and when intravitrealy injected (0.05mg/0.1ml), vitreoretinopathy was more increased than the control group. This result was probably caused by high concentration of retinoic acid in vitreous and further evaluation with various concentration of retinoic acid is needed. In conclusion, we recommend a rabbit fibroblast and subconjunctival injection of retinoic acid for the study on the suppressive effect of proliferative vitreoretinopathy.

Secondary eyeball injury can be caused by head injury as well as direct injury of the eyeball or the orbit. Authors of this report have researched on 117 patients who were applied for ophthalmic examination which in care of the neurosurgical department and have researched frequency of secondary eyeball injury, association between the eyeball injury and the head injury, and favourable frequency of the eyeball injury which were developed without direct injury of the eyeball. There were 21 eyes(9.0%) with external ocular abnormality in 18 patients which included lagophthalmos, ptosis, paralytic strabismus, and there were 14 eyes(6.0 %) with posterior segment abnormality which were vitreoretinal hemorrhage, option. injury and papilledema in 11 patients. In association between the head injury and the eyeball injury, there were many external paralytic injury in basal skull injury and many posterior segment injury in cerebral parenchymal injury. After their injury, follow-up was executed in 3 month interval for 12 month. 15 eyes with external ocular abnormality and 8 eyes with posterior segment abnormality showed favourable progression. Posterior segment abnormality improved statistically significant at 3 month after injury(p<0.05). Secondary ophthalmic injury can be caused by various head injuries. Based on periodic observation, external ocular abnormality improved frequently at more than 9 months after injury. In cases of posterior segment abnormality, there was statistically significant improvement at 3 month after injury(p<0.05). Thus careful observation and treatment should be made in its early stage.

Taxol, an anticancer drug, blocks cell division by stabilizing microtubules. However, taxol has distinct cell-cycle-independent effects. For example, taxol and bacterial LPS induce strikingly similar responses in murine microglial cells. Here, we report that taxol, like LPS, provides a ""second"" signal for murine microglial cell activation to induce tumoricidal activity. Tumoricidal activity determined by MTT assay appeared that taxol or LPS alone weakly activated microglial cells to kill P815 mastocytoma cells, whereas combinations of taxol or LPS with IFN-r synergized to activate macrophages to lyse tumor cells in a dose dependent manner. Secretion of nitric oxide (NO) correlated with tumor cell killing, and the activated microglial cells failed to kill tumor cell targets in the presence of N'-monomethyl-L-arginine (N'MMA), a competitive inhibitor of NO synthase (NOS). Treatment of the cells with anti-TNF-a neutralizing antibodies clearly blocked taxol plus IFN-r induced tumoricidal activity as well as NO production. Collectively, the data illustrate the potential for taxol to activate microglial cell mediated-antitumor mechanisms in addition to its better characterized role as an anti-mitotic agent.

BACKGROUND: Adhesion molecules are related to cell-to-cell interaction and inflammatory interaction. In addition, adhesive interactions between tumor cells and adjacent cells and/or extracellular matrix play important roles in the complex process of tumor growth and development. Among these adhesion molecules, expression of intercellular adhesion molecule-1 (ICAM-1) has been identified in colon cancer, bladder cancer, lung cancer, melanoma, pancreatic cancer and hepatocellular carcinoma. In the current study, we analyzed serum ICAM-1 concentrations to investigate the relationship between the serum ICAM-1 level and prognosis in patients with lung cancer METHODS: Serum ICAM-1 was measured in 84 patients with lung cancer according to the pathologic type and clinical stage using the ICAM-1 ELISA kit. The Kaplan-Meier method was used to analyse survival time. RESULTS: There was no difference in serum ICAM-1 concentration among the different stages of lung cancer. Furthermore, there was no difference observed between histologic tumor type with regard to serum ICAM-1 concentration. Although the difference was not significant, the overall survival times of patients with a low serum ICAM-1 concentration (< 306 ng/mL) was longer than that of patients with a high concentration (> or=306 ng/mL) in non-small cell lung cancer patients. CONCLUSION: These results suggest that high levels of serum ICAM-1 reflect poor prognosis for patients with non-small cell lung cancer.

STUDY DESIGN: Genetic screening of the estrogen receptor 2 (ESR2) genes in patients with ossification of the posterior longitudinal ligament (OPLL). OBJECTIVE: We studied the relationships between ESR2 gene polymorphisms and OPLL to understand the pathophysiology of OPLL. SUMMARY OF LITERATURE REVIEW: The OPLL has a strong genetic component. Several familial surveys and human leukocyte antigen (HLA) haplotype studies reveal that genetic background is an important component in the occurrence of OPLL and a large number of gene analysis studies were utilized to clarify the susceptible gene for OPLL, including COL11A2, BMP-2, TNF-alpha, NPPS, leptin receptor, transforming growth factor (TGF)-beta, Retinoic X receptor, ER, IL-1, PTH, and VDR have been performed. MATERIALS AND METHOD: Genomic deoxyribonucleic acid (DNA) samples obtained from 164 patients (93 men and 71 women) with OPLL and 219 control subjects, without the disease (105 men and 114 women) were amplified by polymerase chain reaction, and polymorphism genotypes were determined by the restriction endonuclease digestion. The distribution of genotypes was compared between the patients with the disease and the control subjects. RESULTS: The polymorphism of ESR2 [rs1256049, exon6, Val328Val, p=0.018, odd ratio (OR)=2.41, 95 confidence interval (CI)=1.15-5.02 in the recessive model] only showed statistically significant association between the control and the OPLL groups. The rest SNPs of ESR2 did not show any significant differences between the control and the OPLL groups. CONCLUSIONS: Estrogen receptor 2 (ESR2) gene polymorphisms (rs 1256049) was associated with OPLL. In future studies, we will perform target SNP chip between OPLL and candidate gene.
