After Drainage implant surgery, erosion of conjunctiva or cornea over tube can occur about 5%in late postoperative period. Scleral allograft for exposed tube should be used to prevent secondary infection. We report three glaucoma patients treated graft with autologous buccal mucosal transplantation for recurrent tube exposure. First case was a 68-year-old male patient with neovascular glaucoma due to central retinal vein occlusion. Second case was a 37-year-old female patient with pseudophakic glaucoma. Third case was a 70-year-old male patient with diabetic neovascular glaucoma. Ahmed glaucoma valve implant surgeries were done for three patients. For tube exposure, we used autologous buccal mucosal transplantation. There was no recurrent erosion and intraocular pressure was maintained well more than 6 months of follow-up. In cases for tube exposure, we introduce that autologous buccal mucosal transplantation can be used to treat tube exposure.

Systemic sclerosis is a generalized connective tissue disorder. It is characterized by fibrosis, degenerative changes and vascular lesions affecting the skin, joints, skeletal muscles and multiple internal organs. Clinical renal disease in systemic sclerosis ranges from scleroderma renal crisis to more subtle abnormalities. Scleroderma renal crisis is characterized by malignant hypertension and rapidly progressive renal failure. It can be successfully treated with angiotensin converting enzyme inhibitors, but remains the most feared complication of systemic sclerosis. We have experienced a 57 year old female patient who visited emergency room with a sudden onset of mental deterioration, azotemia and oliguria. She was under symptomatic treatment for Raynaud's phenomenon for 2 years. Renal biopsy of the patient showed onion-skin configuration in the interlobular arteries which is characteristic of scleroderma renal crisis. She proceded to maintenance hemodialysis despite a angiotensin converting enzyme inhibitor treatment. We report a case of SRC with a brief review of literature.

PURPOSE OF STUDY: To compare on bone formation between ovariectomized rats and normal rats after graft of alloplastic bone material. MATERIAL AND METHODS: Twenty female rats were used in this study. They were divided into two groups by each ten rats. One group was ovariectomized and grafted alloplastic bone material. Other group was non-ovariectomized and grafted alloplastic bone material. After a healing time of 4 weeks, the animals were sacrificed and decalcified preparations were routinely processed for histologic evaluations. RESULTS: Ovariectomy group was significantly lesser bone formation compared with non-ovariectomy group. CONCLUSIONS: Ovariectomy acts as a negative factor in new bone formation.

BACKGROUND: Cardiac tamponade is associated with the expiratory increase and the expira-tory decrease in left ventricular filling flow. With Doppler echocardiography, we analyzed the respiratory variations of mitral and tricuspid inflows, and pulmonary and hepatic venous flows in patients with cardiac tamponade. METHODS: Respiratory hemodynamic changes in mitral and tricuspid inflows and pulmonary and hepatic venous flows were evaluated using Doppler echocardiography in 13 patients (6 men and 7 women; mean age 51+/-13 years) with large pericardial effusion and clinical cardiac tamponade, and compared the results with those of 11 control subjects (3 men and 8 women, mean age 53+/-13 years). Doppler examination was repeated after pericardiocentesis in 6 patients. RESULTS: Peak velocity of early diastolic mitral inflow (E velocity) decreased during inspiration compared with expiratory increase; the mean percentage change was 40%. Peak velocity of late diastolic mitral inflow (A velocity) decreased 13% during inspiration. E/A ratio decreased 31% during inspiration. Deceleration time (DT) and isovolumic relaxation time (IVRT) increased by 26% and 44%, respectively, during inspiration. But respiratory variations of tricuspid inflow were opposite to those of mitral inflow. Tricuspid E velocity increased during inspiration and decre-ased during expiration. The mean percentage change was 123%, which was larger than thte 40% of mitral inflow. The most characteristic findings of pulmonary venous flow during respiration were the expiratory increases of peak diastolic velocity (DV) and diastolic time-velocity integral (D-TVI). The mean percentage changes of peak systolic velocity (SV), DV and D-TVI during respiration were 27%, 45% and 53% respectively. In contrast, the SV and DV of hepatic venous flow increased during inspiration and decreased during expiration. The respiratory variations of peak systolic reverse flow velocity (SR) and peak diastolic reverse flow velocity (DR) were opposite to those of SV and DV. DR notably increased during expiration, and the mean percentage change was 61%. The ratio of RFI (Inspiratory reverse flow integral) to FFI (forward flow integral) of the tamponade group was 270%. The mean percentage changes of each parameters decreased after pericardiocentesis. CONCLUSION: Patients with cardiac tamponade showed inspiratory increases of diastolic tri-cuspid filling flow and hepatic forward flow. Expiratory increases included diastolic mitral filling flow, pulmonary venous systolic and diastolic flow, and hepatic venous reverse flow. Such res-piratory variations decreased after pericardiocentesis.

PURPOSE: It is very important to obtain vascular access that resists repeated punctures and maintains an adequate blood flow for performing hemodialysis in patients with end stage renal disease. This study was designed to identify the risk factors that may influence the early patency rate of arteriovenous fistulas (AVFs). METHOD: We analyzed 304 cases of AVFs in 299 patients who underwent hemodialysis access surgery in our hospital from January 2000 to March 2007. The rate of early access failure and the risk factors of early access patency were evaluated retrospectively. RESULT: The rate of early access failure of an AVF was 14.5%. The early access failure group showed a higher incidence in women and in the patients with a previous history of ipsilateral central venous catheterization. Further examination by multivariate analysis demonstrated that a history of ipsilateral central venous catheterization was an independent risk factor for early access failure of AVFs. CONCLUSION: A history of ipsilateral central venous catheterization was an independent risk factor for early access failure of AVFs in this study.

OBJECTIVES: Rodenticide Vacor causes a severe peripheral neuropathy in humans. Electrophysiologic studies on a peripheral motor nerve-skeletal system of Vacor-treated rat showed decreased amplitude of muscle action potential without conduction velocity abnormalities. The ultrastructural studies of the neuromuscular junction were performed to clarify the anatomic site of the Vacor-induced peripheral neuropathy in male Wistar rats. METHODS: After oral administration of a single dose of Vacor, 80 mg/kg of body weight, to the experimental animals, neuromuscular junctions within the interosseous muscles of the hind foot were observed in time. RESULTS: No axon terminal change was noted until 24 hours after the administration of Vacor. Remarkable loss of presynaptic vesicles and swollen endoplasmic reticulum in the axon terminal were developed at 3 days after Vacor treatment. Progressive degenerative changes consisting of marked loss of presynaptic vesicles, focal disruption of membrane in the axon terminal with disappearance of the number of the damaged axon terminal appeared, and flattening of postsynaptic folds was also seen. CONCLUSIONS: These results suggest that degenerative changes in axon terminal at neuromuscular junction may contribute to the peripheral neuropathy developed in the early phase of Vacor poisoning.

The purpose of this study was to examine the mRNA levels of TNF-alpha and IL-6 in the cell lines of normal oral keratocyte and oral squamous cell carcinoma. Total RNA was extracted from these cell lines, observed under UV light, developed by radiographic films of PCR products via reverse transcriptase polymerase chain reaction (RT-PCR) amplication, and measured with densitometer. Each mRNA level of these cell lines divided by beta-actin mRNA level was compared to that of normal control group. The results were as follows : 1. Higher mRNA expression of TNF-alpha than IL-6 in the normal oral epithelial cell line. 2. In general, expression of mRNA of IL-6 appeared 3-4 times more in tumor cell lines than in control group. 3. mRNA expression of TNF-alpha showed variable expression in tumor cell lines, unlike normal cell line. 4. There are no special connections between differentiation of oral cancer cell lines and mRNA expression of TNF-alpha and IL-6. From the above results, expression of mRNA of IL-6 in the cell lines of squamous cell carcinoma used in this study has higher than the normal oral epithelial cell line, but there are no relationship between the differentiation of oral cancer cell lines and the expression of mRNA of TNF-alpha and IL-6.
