PURPOSE: Metalloproteinases (MMPs) and tissue inhibitors of metalloproteinase (TIMPs) have been linked to the angiogenic process in general. In order to understand the potential roles of MMPs and TIMPs in corneal neovascularization process, we examined the expression and activities of MMP-2, MMP-9, TIMP-1 and TIMP-2 during the course of suture-induced corneal neovascularization in rat model. METHODS: Corneal neovascularization of rat cornea was induced by suturing. The expression of MMP-2, MMP-9, TIMP-1 and TIMP-2 in sutured corneas was examined by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR). The activities of MMP-2 and MMP-9 were measured before and after suture by gelatin zymography. RESULTS: MMP-2 proenzyme, and TIMP-1, -2 were expressed in normal corneas, predominantly in corneal epithelium. After injury, expression of MMP-2, MMP-9, TIMP-1 and TIMP-2 increased, notably in healing corneal epithelium, infiltrating inflammatory cells, stromal fibroblasts, and ingrowing vascular endothelial cells. The intensity of immunostaining and enzymatic activities of MMP-2 and MMP-9 paralleled the magnitude of inflammatory cell infiltration, which peaked around day 7 after suture. Immunoreactivity of MMP/TIMP decreased significantly two weeks after suturing. At day 35 after suture, staining of MMP-2, TIMP-1, -2 remained visible only in corneal epithelium and vascular endothelial cells. CONCLUSIONS: MMPs as well as TIMPs were upregulated during suture-induced corneal neo-vascularization, suggesting that both may take part in extracellular matrix remodeling in the corneal wound healing, inflammatory, and neovascularization processes.

PURPOSE: The purpose of this study is to illustrate MR patterns of bone marrow of calvarium and vertebral body in normal subjects according the age distribution and to understand the course of the fatty replacement from red marrow. METHODS AND MATERIAL: We retrospectively evaluated MR examinations of the calvaria(n=71), cervical spine(n=71), thoracic spine(n=65), Imbar spine(n =68) in subjects without bone marrow abnormality whose age ranged 3 weeks to 74 years. Three distinctive patterns were categorized on Tl-weighted images of the skull. In pattern 1, uniformly low signal intensity with or without very small areas of high intensity in frontal and occipital bones is noted. In pattern 2, frontal and occipital bones have uniformly high signal intensity, and patchy area of high intensity appears in parietal bone. In pattern 3, the entire skull has uniformly high signal intensity. In the spine, four patterns were categorized on Tl-weighted MR images. In pattern 1, the vertebral body has uniformly low signal intensity except for linear areas of high intensity superior and inferior to basivertebral vein. In pattern 2, bandlike and triangular areas of high signal intensity are found in the periphery. Pattern 3 and 4 have diffusely distributed areas of high signal intensity; pattern 3 consist of numerous indistinct dots measuring a few millimeter or less, and pattern 4 consist of fairly well marginated areas ranging in size from 5 to 1.5cm. RESULT:In the calvaria, 73% of pattern 1 were younger than 20 years, pattern 2 were evenly distributed, and 86% of pattern 3 were older than 40 years. In the spine, 87% of pattern 1 were younger than 40 years, 72% of pattern 3 were in 40 to 50 years, and 87% of pattern 4 were older than 50 years. Pattern 2 were evenly distributed in the cervical and thoracic spine, but in the thoracic spine 62% were younger than 30 years. CONCLUSION:It is concluded that younger age group shows mainly pattern 1, whereas elderly group has pattern 3 or 4 in the calvarial and vertebral body marrow. This suggests that conversion to fatty marrow begin locally and progress diffusely with age.

PURPOSE: There have only been a few studies on optimal usage of injection material in the regional nerve block for lower extremity operations. The purpose of this study was to evaluate the efficacy of different concentrations of ropivacaine. MATERIALS AND METHODS: A total of 339 patients underwent lower extremity surgery under ultrasound-guided nerve block (combined femoral and sciatic nerve block) at a Chungnam National University Hospital between March 2016 and February 2017 and were randomly assigned to three groups: Group A (0.5%, 44 ml), group B (0.6%, 30 ml), and group C (0.75%, 30 ml). The interval between nerve block procedure and onset of the complete anesthetic effect (complete anesthetic time) was investigated. The degrees of intraoperative pain, and postoperative pain were evaluated using a visual analogue scale (VAS) score. Patient's satisfaction (0–10) was investigated. To evaluate the efficacy in accordance with the concentration under the same dose and same volume, group A and B were compared with group C respectively. RESULTS: There were 108, 118, and 113, in groups A, B, and C, respectively; and there were no significant differences with respect to the number, age, sex, and type of operation (p>0.05). The mean complete anesthetic times were 78.5, 76.4, and 58.6 minutes, respectively. The mean intraoperative VAS scores were 2.04, 0.62, and 0.24; and the mean postoperative VAS scores (6 hours/12 hours) were 2.41/4.08, 0.27/1.24, and 0.38/1.54. The mean patient's satisfactory scores were 8.53, 9.38, and 9.40, respectively. Compared with group C, group A showed significantly longer complete anesthetic time (p < 0.05) and higher intra, postoperative VAS scores (all p < 0.05). Group B showed longer complete anesthetic time (p < 0.05), but no significant difference of intra, postoperative VAS scores (all p>0.05). Patient's satisfactory scores in both group A and B were similar to group C (p>0.05, p>0.05). There were no specific adverse reactions in all groups. CONCLUSION: Ropivacaine 0.6% as well as 0.75% are safe and effective anesthetics under the same volume (30 ml) for regional nerve block of the lower extremity. However, taking into account of the longer complete anesthetic time, the operation start time must be adjusted.

Rotational vertebral artery syndrome (RVAS) is a rare disease entity. RVAS is characterized by recurrent attacks of vertigo, nystagmus, ataxia, and tinnitus, which is elicited by head-rotation when the contralateral dominant vertebral artery is compressed, leading to an acute reduction of blood flow in the vertebrobasilar territory. A 50-year-old female presented with a whirling type vertigo which, when turning her head to the left, compressed the dominant right vertebral artery, as documented by the dynamic neck angiography. The patient underwent posterior cervical decompression of the foramina transversaria and the surrounding soft tissues at the level of C1-C2. The patients's symptom disappeared after the surgery and she has been followed up for the last four months without the recurrence of vertigo.

BACKGROUND: Automated external defibrillator(AED) represent a major breakdown to permit more widespread application of the principle of early defibrillation. Many recent efforts to improve emergency medical services(EMS) and increase survival rates are simply efforts to get defibrillation to patients as rapidly as possible. AED is major innovation for the prehospital care of ventricular fibrillation cardiac arrest patients. The purpose of this study is to evaluate the course of initial training to three different groups(nurses, firefighters, and EMT trainee) to use AED. METHOD: We studies the efficacy of education of AED to 33 nurses, 15 EMT trainee, and 16 firefighters. Training lasted 75 mins and included 45 mins an overview of defibrillation, protocols for using the AED, and operation of the AED(Laerdal Heartstart 3000),15 mins demonstraion.4 check list was used to grade the performance of cardiopulmonary resuscitation, operation of the AED, and the time required to deliver the first three defibrillations. RESULT: There were no statistically significant differences in performance and time required to deliver an electrical countershock among the groups(p=0.4). To the second test 92fo of all group completed all steps successfully. The step most often foiled was the preparing of the AED for defibrillation. CONCLUSION: In nurses, EMT trainee, and firefighters, it is both feasible and effective to train AED use irrespective of the degree of the trainee.
