We have tried this experiments about measure of Human Body Fat from transverse body scans with Magnetic Resonance Image (0.5, Tesla). Images were created with a spin echo sequence using a repetition time 500msec, echo time 20msec, and 1cm length between 10mm cross sectional slices, and gained through a whole body. In vivo quantification of body fat with MRI was measured by two healthy Females Volunteers, each cut obtained with MRI was analyzed, traced papers on the view finder, and then digitized, at last calculated for the areas of Human Body Fat. The results of this study can be summarized as follows : Through the analyses of the Ratio of Human Body % Fat with MRI and Densitiometry, in Sub.1, Sub.2, MRI is estimated higher than Densitiometry, that is, Keys & Brozek's Method (1960) has the most remarkable score gaps, 6.94% (Sub.1), 6.21%(Sub.2). Chinn & Alleys Method (1960) has showed the score getting closest to MRI, 1.67% (Sub.1), 1.36%(Sub.2). And Siri's (1956) Brozek et al's (1963), which have been used as the most popular methods, make the difference of 4% approximately. As a result of this study, such as preceding studies about it Ratio of Human Body Composition with MRI has considered to be validated and trusted. Therefore, if we estimate for Ratio of Human Body Fat with much more subjects than this experiments we can suggest that the method with MRI is possible to develope low data adaptable in every field.

Neurilemoma is benign never-sheath tumor which has been described as painless mass and is usually discovered incidentally. It is the most common tumor of peripheral nerve origin and may arise in any nerve where Schwann cells occur. There are few domestic reports which were clinically evaluated in tens of cases of neurilemoma so far. We evaluated on the 56 cases of neurilemoma confined to the trunk and extremities, in the aspect of clinical characteristics, radiology, pathology, EMG, surgical treatment and postoperative results, who were surgically treated at the Department of Orthopedic Surgery of Seoul National University from 1984 to 1994. Among 56 patients, male were 29 and female were 27, and there was no sexual difference. The average age at surgical intervention was 46.4 years (16–83yrs) and 46.4% of patients were in the age of fourties and fifties. The anatomical locations of the tumors were as followed: upper extremities in 22(39%) cases, neck and supraclavicular area in 15(27%) cases, sacrum and lower extremities in 14(25%) cases and trunk in 5(9%) cases. Symptoms were palpable mass in 55 cases, local tenderness in 14, radiating pain in 11, pain in 10, paresthesia in 11, motor weakness in 2 cases. The average follow up period was 19.1 months(13–56 month). Median nerve was involved most frequently(14%), then ulnar nerve(11%). There was no cases which occurred in multiplicity or associated with neurofibromatosis. Marginal excision was done in 51 cases(91%), incisional biopsy only in 4 cases(7%), wide excision in 1 case. The size of the tumors in the longest axis was smaller than 2cm in 9 cases, between 2 and 4cm in 31 cases, between 4 and 6cm in 13 cases and more than 6cm in 3 cases. Malignant change or recurrence was not found in all cases.

The amplification of c-myc oncogene was evaluated in 42 cases of ovarian carcinomas to correlate with clinical parameters. Using oligonucleotide primers, sequences from the c-myc exon-3 gene and from a control gene, tissue plasminogen activator (tPA), were amplified simultaneously by polymerase chain reaction (PCR). After the products of differential PCR (d-PCR) were electrophoresed, slot blot hybridization was performed, and hybridized with P32 dATP-labeled myc and tPA oligonucleotide probes and then autoradiographed. The signal intensities of the two products were quantitated by densitometry and the ratios of two products (c-myc/tPA) were measured. The ovarian carcinomas showed significantly increased amplification of c-myc oncogene Oligonucleoti compared to normal control group (p<0.05). 15 of 42 cases (35.7%) showed various degrees of the MYC gene amplification up to 27 folds in various histologic types of ovarian carcinomas. No significant differences of the MYC gene amplification according to histologic subtypes, tumor action) grades and clinical stages of ovarian carcinomas were present.

Maintaining the blood supply of the interdental alveolar bone is crucial for preserving the interdental papilla. Rebuilding the interimplant papilla between adjacent implants is more difficult than rebuilding the interdental papilla between the natural tooth and implant. Therefore, preserving the interimplant tissue is necessary when adjacent implants are closely placed. In this case report, three effective methods for maintaining the surrounding tissue, namely strategic serial extraction, immediate implantation, and provisionalization of adjacent maxillary central incisors, were performed. The marginal gingiva and interimplant papilla were well maintained for 24 months.

PURPOSE: To compare the efficacy of the transconjunctival releasable suture technique for pars plana vitrectomy using 23-gauge (23G) instruments versus the conventional 20-gauge (20G) technique. METHODS: A retrospective and interventional case series was consecutively performed for 199 eyes of the 192 patients that were a part of this study. Clinical data were reviewed retrospectively regarding the operation time, preoperative and postoperative intraocular pressure, visual acuity and astigmatism for 54 consecutive patients who received a 23G releasable suture vitrectomy and for 98 consecutive patients who received a 20G conventional vitrectomy during the period between April 2007 and September 2010. RESULTS: Mean operation time based on the operation record was 88.5 +/- 20.1 minutes in the 23G releasable suture vitrectomy group and 102.1 +/- 23.1 minutes in the 20G conventional vitrectomy group, respectively (p = 0.01). The last best-corrected visual acuity (BCVA) was significantly better than the preoperative BCVA in both patient groups (p = 0.01, p = 0.01). The 23G releasable suture group showed less surgically induced astigmatism than the 20G conventional vitrectomy group. Vitreous bleeding was observed to be in 6 eyes (5.9%) in the 23G group, and in 8 eyes (8.2%) in the 20G group. In addition, ocular hypertension was noted to be in 3 eyes (3.0%) in the 23G group, and 6 eyes (6.1%) in the 20G group. No serious complications such as postoperative hypotony or endophthalmitis were observed in either group. CONCLUSIONS: The 23G releasable suture technique is as effective as the 20G conventional technique and offers several advantages.

PURPOSE: To evaluate factors associated with the direction of horizontal deviation in the sensory strabismus of patients with unilateral organic amblyopia. METHODS: The medical charts of 53 patients who had been diagnosed with sensory strabismus between 2000 and 2009 were reviewed retrospectively. The underlying ocular disease, time of onset and the duration of vision impairment, refractive error and axial length of the fixing eye, and the direction and angle of deviation were analyzed to determine the distribution of underlying diseases and any factors relevant to determining the direction of the horizontal deviation. RESULTS: Congenital cataracts were the most common underlying disease, found in 33 patients, followed by acquired cataracts, optic nerve disorders, retinal detachment, glaucoma and lens subluxation. Among the 50 patients with horizontal strabismus, 11 had esotropia and 39 had exotropia. The incidence of esotropia was significantly higher when the fixing eye had hyperopia or emmetropia, than when the eye was myopic. Age of onset of vision deterioration and at diagnosis of sensory strabismus, and the axial length of the fixing eye had no relationship to the direction of horizontal deviation. In addition, the duration of visual impairment had no significant relationship with the direction or extent of horizontal deviation. CONCLUSIONS: The most common cause of sensory strabismus was congenital cataracts and the most frequent type of strabismus was exotropia. With respect to the direction of horizontal strabismus, esotropia occurred significantly more often when the refractive error of the fixing eye was hyperopia or emmetropia than when the fixing eye was myopic.
