1.A Clinical Observation on Donor Nephrectomy for Renal Transplantation Using horacoretroperitoneal Approach.
Korean Journal of Urology 1979;20(5):463-467
A clinical observation was made on 10 donors for renal transplantation which were done at dept. of urology university hospital from April 1978. to August 1978. The following results were observed: 1. Donors were 3 male and 7 female, aged ranging from 1970 to years old. The most common age group was fifties 2. The related donors were 9 and unrelated was 1. 3. Seven donors had sam ABO blood type with the recipient and 3 had different. The HL-A match grade showed that 2 were B grade and 1 was C grade and 7 were D grade. The failed 3 patient had same ABO blood type with donor and all in D grade. 4. Seven were nephrectomized left and 3 were right. The postoperative course were all uneventful and discharged from POD 9 to 13. 5. The thoracoretroperitoneal approach used for donor nephrectomy: gave good operative field and easy operative technique.

2.A Statistical Study of Recurrent Urolithiasis Preliminary Report.
Korean Journal of Urology 1978;19(6):537-543
A statistical analysis was made on patient of recurrent urinary stones during the period from May 1972 to April 1977 in the Department of Urology of Han Yang University Hospital and the results were obtained as following: 1. Among the 894 patient of in-patient, 290 patient were urinary stone patients (32.8 %). 2. The recurrent patients were 11 (20%), with the follow-up period from 1 year to 10 years, in whom follow-up was possible. 3. The most common age group of recurrent stones were from 20 to 40 years old ( 72.8%). 4. The mean period from primary stone to recurrent stone was 4.4 years. 5. Among the recurrent patient, 2 were prolonged recumbency patients and one had duplicated ureter. Others were idiopathic recurrent stones. 6. If the primary stone was removed by operation, recurrent stone was some hard to be passed spontaneously.

In Asia, mammography following the injection of foreign materials into the breasts for cosmetic augmentation is frequently seen and diagnosis based on the typical radiologic findings is straightforward. We report the unusual radiologic findings in two patients with foreign body granulomas caused by injected foreign materials and discovered incidentally during screening work up. The mammographic findings were bilateral, hyperdense, spiculated masses, with occasional microcalcification, and at sonography, markedly hypoechoic, spiculated solid masses, located near the pectoralis muscle and partly extending into it, were observed. These radiologic findings mimicked malignancy.

5.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.

Medulloepithelioma(diktyoma) is a uncommon congenital tumor that is generally believed to arise from the embryonic neuroepithelium of the medullary tube. This tumor usually arises from the ciliary body epithelium. But medulloepitheliomas of the retina and optic nerve may also occur, although it is extremely rare, because the embryonal medullary epithelium that lines the optic vesicle is continuous with the epithelium lining the cavity of the optic nerve during the early embryonal period. The occurrence of medulloepithelioma of the optic nerve is exceptionally rare, with only a few cases have been previously reported. We report a first case of medulloep-ithelioma of the optic nerve head in Korea in a 5-year-old girl who presented with a poor vision and squint of the left eye.

8.The Effect of Nitric Oxide on Cultured Bovine Retinal Pigment Epithelial Cell.
Journal of the Korean Ophthalmological Society 1996;37(12):2048-2058
Nitric oxide (NO), a potencially toxic radical, is generally regarded as a multi-potent molecule to be implicated in a wide range of biological function. The presence of nitric oxide synthase(NOS) in the retina, the constitutive isoform in photoreceptor outer segments and and the inducible form in retinal pigment epithelial (RPE) cells, has been demonstrated. The effect of NO in retina has been studying mainly as neurotransmitter. Present study was undertaken to find the role of NO in cultured bovine retinal pigment epithelial cells. Cultured bovine retinal pigment epithelial cells were treated with various concentrations of NO generator, S-nitroso-N-acetyl-D, L-penicillamine (SNAP). The survival fractions were measured by MTT assay. The morphologic changes were observed with inverted phase contrast microscope and electron microscope. To evaluate the characteristics of cell death, cells were lysed for DNA extraction, and the agarose gel electrophoresis was done. NO brought a decrease in the survival fraction of cultured bovine retinal pigment epithelial cells as concentrations increased. At high concentrations, cells became sparse. Electron microscopic study showed destruction of nuclear membrane and chromatin condensation in 1 mM SNAP treated group. These findings were compatible with apoptotic cell death that was supported with DNA laddering pattern in agarose gel electrophoresis. NO can induce damage to retinal pigment epithelial cells, and damaged cells are destined to apoptotic cell death.

Solid pseudopapillary tumor of the pancreas is a rare tumor that affects young females with low malignant potential and good prognosis with more than 90% survival at 5 years. Metastasis is very rare. We report the case of a 74-year-old female who had pancreatic solid-pseudopapillary tumor and synchronous hepatic metastasis.

A case of clear cell adenocarcinoma arising in the female urinary bladder, which is accompanied by endometriosis of the urinary bladder and the uterus, is reported. The carcinoma protruded into the vesical lumen as a fungating mass, and had a tubulocyotic pattern. The tumor cell had intracytoplasmic glycogen and electron microscopically short microvilli on their surface, resembling clear cell acenocarcinoma of the female genital tract including ovary. This is the fourth case report of clear cell adenocarcinoma complicating vesical endometriosis, and may support the view that clear cell carcinome arises from endometriosis which, in turn, from the Mullerian remnant.
