We analysed a retrospective study of 22 aphakic bullous keratopathy patients (22 eyes) with penetrating keratoplasty for 5 years from January 1987 to December 1991 in the Department of Ophthalmology at St. Mary's Hospital, Catholic University Medical College. The results were as follows; 1. Of the 22 eyes with aphakic bullous keratopathy 16 eyes (72.7%) had previously undergone intracapsular cataract extraction, 6 eyes (27.3%) had extracapsular cataract extraction. 2. The mean time from cataract extraction to aphakic bullous keratopathy to penetrating keratoplasty was 13.8 months. 3. After keratoplasty, the visual acuity of 20 among the 22 transplants (90.9%) were significantly improved compared to the preoperative levels, however that of 2 among the 22 transplants were worse than the preoperative levels. The factors limiting postoperative visual acuity were senile macular degeneration and graft failure. 4. Postoperative complications were glaucoma (2 eyes, 9.1%), cystoid macular edema (1 eye, 4.6%) and graft failure (1 eye, 4.6%).

Phenylketonuria is metabolic disorder that results from a deficiency of the hepatic phenylalanine hydroxylase. But among patients with hyperphenylalaninemia, the defect resides in one of the enzymes necessary for production or recycling of tetrahydrobiopterin (BH4). The reduction of BH4 affects not only phenylalanine metabolism but also formation of the tyrosine related neurotransmitter, dopamin and tryptophan related neurotransmitter, serotonin. Administration of L-dopa and 5-hydroxytriptophan seems to be the most effective treatment and may prevent irreversible neurologic damage if started early in life in hyperphenylalaninemia due to deficiency of cofactor BH4. Therefore, all patients with PKU and hyperphenylalaninemia should be tested for BH4 deficiency as early as passible. So we measured reduced forms of biopterin in urines of 19 phenylketonuria patients by Funkushima and Nixon method and 13 of PKU patients measured dihydropterin reductase (DHPR) in white blood cells by modified Narisawa method. We could not find abnormal pterin patterns of cofactor BH4 and normal value of DHPR. All Korean 19 PKU children were classic PKU. A missense mutation has been identified in the phenylalanine hydroxylase (PAH) gene of 16 Koran PKU patients. 5 mutations (IVS4, Y204 C, R243Q, Y356 X, R413 P) have been identified. The frequency of these mutations was found to be 50% of PKU alleles. The IVS4 mutation had a high frequency in Korea and southern China, due to the result of the founder effect and genetic drift. the R413 P mutation, which may have originated in the regions surrounding the Baikal, expanded to northen China and Japan. We were not able to find Caucasian mutations in Korean ptiets. PKU mutations occured after racial divergence between Caucasian and Mongoloids. We observed that PKU patients with Y 204 C and R413 P mutations showed mild mild clinical phenotype but IVS4 mutation had severe mental retardation. the establishment of genotype will therefore aid in the prediction of clinical phenotypes in patients with this disease. So, pterin and DHPR measurement and DNA analsis will be useful for prognosis and proper treatment of PKU patients.

Hyperreflexic bladder is a disease manifested in patients with spinal cord lesions above the sacral segment. The treatments for hyperreflexic bladder are medical therapy, interruption of innervation, argumentation cystoplasty, etc. We treated four hyperreflexic bladder patients with 12% a phenol injection into the subarachnoid space for sacral nerve block. Before treatment the average bladder capacity was about 100 ml, and there was one case of autonomic dysreflexia. After the subarachnoid block the average bladder capacity increased above 300 ml and maximal intravesical pressure decreased below 30cmH2O, autonomic dysreflexia disappeared in one patient. The decreased bladder compliance after nerve block was managed by repetitive bladder overdistention. We suggest that subarachnoid block is easier and more effective than sacral nerve block individually, and is a treatment for hyperreflexic bladder refractory to medical therapy.

The authors presented 9 cases of surgically treated CSF rhinorrhea, two of which were spontaneous and 7 were traumatic delayed. The duration of leakage was longer than 1 month in most cases and seven of the nine cases were complicated by meningitis. The leakage site was most accurately detected by metrizamide computed tomographic cisternography(MCTC) and the most frequent leakage site was the cribriform plate. Good surgical results were obtained by direct repair and/or shunt without recurrence during follow-up period from 7 months to 2 years.

OBJECTIVE: T(-)-Epigallocatechin gallate(EGCG) `a green tea polyphenol' is a potent antioxidant and known to reduce the free radical-induced lipid peroxidation. In our previous study, systemic administration of EGCG immediately after ischemia has been shown to inhibit the hippocampal neuronal damage in the gerbil model of global ischemia. Polyamines, especially putrescine(PU) is thought to be important in the generation of brain edema and neuronal cell damage associated with various types of excitotoxic neuronal injury. We investigate the effects of delayed administration of EGCG on the changes in polyamine levels and neuronal damage after transient global ischemia in gerbils. METHODS: To produce transient global ischemia, both common carotid arteries were occluded for 3 min with micro-clips. The gerbils were treated with EGCG(50mg/kg, i.p.) immediately or 2hr after ischemia. Putrescine levels were examined in the cerebral cortex and hippocampus 24 hours after ischemia using high performance liquid chromatography. RESULTS: PU levels in the cerebral cortex and hippocampus were increased significantly after the ischemia. The administrations of EGCG immediately after the ischemia attenuated the ischemia-induced increase of PU level, however, 2 hr delayed EGCG administration did not reduce the increase of PU level. EGCG administered immediately or 2 hr after ischemia significantly reduced neuronal damage in the hippocampal CA1 region, respectively. CONCLUSION: These findings suggest that EGCG may has a promise in the management of stroke.

Journal of Cerebrovascular and Endovascular Neurosurgery 2012;14(3):186-191
OBJECTIVE: The objective of this study is to verify the relationship between subarachnoid hemorrhage (SAH) volume (not Fisher grade) and development of cerebral vasospasm prospectively. METHODS: Patients who visited our hospital with a diffuse or localized thick subarachnoid blood clot seen on computed tomography (CT), taken within 48 hours after SAH and the aneurysm was confirmed by CT Angiogram (CTA) from March 2010 to July 2011 were enrolled in this study. CTA was checked at least twice after admission. Angiographic vasospasm (AVS) on CTA was defined as irregularity or narrowing of intracranial vessels on follow up CTA compared with initial CTA. Total intracranial hemorrhage (ICH) volume (subdural, SAH, intracerebral and intraventricular) was calculated and SAH volume (all supratentorial and infratentorial cisterns) was also calculated using the MIPAV software package. RESULTS: A total of 55 patients were included in our study. Thirty six patients did not show AVS on CTA or clinical deterioration (non vasospasm group: NVS). AVS without ischemic neurologic symptoms was observed in four patients and development of symptomatic vasospasm (SVS), defined as AVS with ischemic symptoms, was observed in 15 patients. SAH volume in SVS patients was statistically larger than that in NVS patients (p < 0.05). Total ICH volume in SVS patients was larger than that in NVS patients. However, the difference was not statistically significant. CONCLUSION: Results of this study indicate an association of development of vasospasm with the SAH volume, not intracranial hemorrhage.
