We analyzed the clinical result of trabeculectomy with amniotic membrane transplantation which has antifibrotic and antiinflammatory action in risky glaucoma patients. Subjects were included four eyes of four patients with neovascular glaucoma, one eye of one patient with primary open angle glaucoma and four eyes of three patients with congenital glaucoma. After limbal based scleral flap was made in triangular shape with 5x4 mm sized, amniotic membrane, sized by 6x6 mm with epithelial side up, was placed on the scleral flap and then sutured to medial and lateral portion at 3 mm superior to base of scleral flap base with 10-0 nylon(2 points). The state of bleb, intraocular pressure and complications were observed at postoperative 1st, 3rd, 6th and 9th week. The IOP was reduced from 33.6+/-11.1 mmHg, to 15.5+/-6.5 mmHg at postoperative one week, 17.0+/-8.3 mmHg at three weeks, 16.9+/-8.1 mmHg at six weeks, 17.1+/-6.4 mmHg at nine weeks. 6 eyes(77.7%)had controlled IOP under 21 mmHg without antiglaucomatous agents at last follow up. Avascular blebs were observed throughout postoperative period in all subjects. Postoperative complications were shallow anterior chamber in one eye at 1st week and low intraocular pressue in one eye at 1st, 3rd week, that resolved at six weeks. Trabeculectomy with amniotic membrane transplantation on the scleral flap appeared to be effective as an augment therapy for filtering surgery in risky glaucoma.

PURPOSE: To evaluate the effect of amniotic membrane transplantation which has anti-inflammatory functions and facilitates epithelialization on leaking blebs. METHODS: Patients who had bleb leakage after trabeculectomy were included, 2 eyes of 2 patients with primary open-angle glaucoma and 1 eye of 1 pa-tient with primary angle-closure glaucoma. After amniotic membrane was transplanted in the conjunctiva and cornea at the center of bleb leakage, the state of bleb leakage was observed retrospectively. RESULTS: In the first patient, there was no bleb leakage at postoperative day 1 and showed epithelialization at postoperative day 10. At two days after surgery, bleb leakage was controlled in the second patient and it showed epithelialization at four days after surgery. From the first day after surgery, there was no bleb leakage in the third patient. The patients were put on T-lens because of foreign body sensation, which was improved two days after surgery, and were epithelialized in 1 week. Out of all three eyes, there was no avascular bleb with leakage. CONCLUSION: Amniotic membrane can be a useful therapy of bleb leakage , which may cause the complications after trabeculectomy in glaucoma patients.

OBJECTIVE: To evaluate the changes of maximum fibrillation potential amplitude and root- mean-square (RMS) value of denervation potential after nerve injury using power spectrum analysis. METHODS: The sciatic nerve was transected in 8 rats, and was compressed in 6 rats. Denervation potentials were collected in gastrocnemius using monopolar needle weekly after nerve injury. The change of RMS value of 1 second epoch of denervation potentials with time was evaluated and compared with the change of maximun fibrillation potential amplitude. RESULTS: In nerve-transected rat, the RMS value declined linearly with time after injury. On the contrary, the amplitude of fibrillation potentials declined much rapidly during first 3 weeks. In nerve-compressed rat, both the RMS value and amplitude of fibrillation potential increased for 2 weeks after injury, and declined thereafter. As the result of simple regression analysis, the changes of RMS value correlated better than changes of fibrillation amplitude in all 8 nerve-transected rat. CONCLUSION: The RMS value of denervation potentials correlated well with time after nerve injury in animal experiments. Measurement of the RMS value might be helpful to evaluate the time after peripheral nerve injury, but long-term human data should be essential for clinical application.

This study was performed to evaluate the relationship between biological markers of lead exposure and thyroid functions among male workers occupationally exposed to inorganic lead. 30 male workers exposed to inorganic lead at smelting and battery factories were investigated, and 30 male control workers who were not exposed to inorganic lead occupationally were chosen for this study. The data were obtained using direct interview and assessment of biological markers of lead exposure and thyroid indices. As biological markers for lead exposure, blood ZPP. blood lead, urine lead and hemoglobin were measured. As thyroid indices. TSH and FT4were determined. The results of the study were summarized as follows 1. Levels of ZPP, blood lead, and urine lead were significantly higher in lead-exposed group than in nonexposed control group(p<0.01 all). Hemoglobin level was significantly lower in lead-exposed group than in nonexposed group(p<0.01). 2. Study subjects had normal values of TSH and FT4 But TSH level was insignificantly lower in lead-exposed group than in nonexposed control group(p=0.11) and FT4 level was significantly lower in lead-exposed group than in nonexposed group(p<0.01). 3. As the result of simple regression analysis in lead-exposed group. FT4 level was negatively correlated with the amount of smoke, blood ZPP, and blood lead(p < 0.05 all). 4. In lead-exposed group, FT4 was used as a independent variable and age, the amount of smoke, blood ZPP, and blood lead were entered as a dependent variables in the model. As the result of multiple regression analysis with stepwise selection method, the amount of smoke and blood ZPP were negative predictors of FT4(p=0. 04, p=0.09, respectively). In conclusion, levels of TSH and FT4were lower in lead-exposed group than in nonexposed control group. In lead-exposed group, FT4 level was negatively correlated with amount of smoke, blood ZPP, and blood lead in simple regression analysis. To clarify this relation, further research between lead exposure and thyroid function may be required for worker with long-term lead exposure or high lead exposure.

"Mirror-writing" is the simultaneous process of reversing individual letters and composing word strings in reverse direction. It is reported that the lesions which cause "mirror-writing" are left parietal lobe, left basal ganglia, right supplementary motor area, left supplementary motor area, left cingulate gyrus, and left angular gyrus. To explain this phenomenon, several theories have been proposed such as the motor, the visual dominance, the supplementary motor area, the visio-spatial, the visual word- form, the hemisaptial factor or directional and the reflected graphemic representation hypotheses. With reviewing some of literatures, we present a case of "mirror- writing" of posterior corpus callosum lesion which is not included in the aforementioned those.

Crossed aphasia refers to language disturbance induced by unilateral right hemisphere (non-language dominant) injury in right-handed people who had no previous history of brain damage. Crossed aphasia occurs in less than 2 percent who developed a aphasia. We report a case of a 49-year-old right handed man with language disturbance after right middle cerebral infarction. He showed nonfluent crossed aphasia with Gerstman syndrome such as right-left disorientation, finger agnosia, acalculia and agraphia, but not with apraxia and neglect. At 7 weeks after onset, language function indicated improvement in spontaneous speech and at 19 weeks after onset, improvement in spontaneous speech, comprehension, repetition, naming and reading.

The Caudal regression syndrome is characterized by sacrococcygeal or lumbosacrococcygeal agenesis, of variable extent, most often accompanied by multiple musculoskeletal abnormalities of the pelvis and legs. It is rare fetal complication of diabetic pregnancy. Although the exact teratogenic mechanism is not known, hyperglycemia appears to play a crucial role as a teratogen. Strict control of diabetes preconceptually and in early pregnancy is presumed to reduce the risk of occurrence. We report a case of caudal regression syndrome detected by pelvic radiography and MRI in the newborn of the diabetic mother.

Subacute sclerosing panencephalitis (SSPE) is a slowly progressing, chronic persistent fatal central nervous system disease, involving gray and white matter, especially white matter caused by measles virus that affecting children and young adult. 45 to 68% of affected individuals had measles before the age of 2. Current knowledge of the pathogenesis of SSPE involves mutation of the measles virus, resulting in lack of production of the M(Matrix)-protein. No therapeutic maneuvour gas been proven conclusively to be of value. But recently intraventricular alpha-interferon (a-IFN) injection combined with oral inosiplex increase the length of survival and may bring remission or stabilization in SSPE. We report a case of SSPE which was diagnosed by history, clinical manifestation, typical EEG findings, high titer of measles antibodies in cerebrospinal fluid and serum by hemagglutinin inhibition method. We tried intraventricular a-IFN injection via Ommaya reservoir and oral inosiplex.

The coexistence of aspergillosis and squamous cell carcinoma (SCC) in the maxillary sinus was very rare. To our knowledge, this is the second report of coexistent SCC and aspergillosis in the maxillary sinus. A 58-year-old man underwent surgery for unilateral maxillary sinus infection with oroantral fistula. In the surgical specimen, SCC and aspergillosis were co-detected with routine and immunohistochemical stainings. Moreover, human papillomavirus 18 (HPV-18) was detected by polymerase chain reaction in the sinus specimen. The patient was re-operated with subtotal maxillectomy and has been followed up for two years without any evidence of recurrence or metastasis. Although it is not understood how aspergillosis could induce carcinoma formation, the chronic inflammation caused by prolonged fungal infection might be carcinogenic. Moreover, HPV-16 and -18 were another causative pathogens of SCC in the head and neck region. We recommend careful examination, including preoperative cytology, in patients with maxillary sinus fungal infections because of the potential for cancer development.
