BACKGROUND: In patients with endometrial carcinoma, preoperative evaluation of exact staging has important prognostic and therapeutic implications. The incidence of pelvic and aortic lymph node involvement in endometrial carcinoma depends on grade of tumor differentiation and depth of myometrial invasion. MATERIAL AND METHOD: To evaluate whether MRI provides a preoperative assessment for staging of endometrial carcinoma, MRI was undertaken in 28 patients, a few weeks before operation. Myometrial invasion was devided in three categories, and involvement of cervix, adnexa, and pelvic cavity were classified. RESULTS: The results of MR imaging were compared with these of pathology. The preoperative MRI staging of endometrial carcinoma was correct in 22 out of 28 patients. In the evaluation of myometrial invasion, the MR imaging underestimated in 4 cases and overestimated in 1 case. CONCLUSION: In patients with endometrial carcinoma, MR imaging is very useful in the assessment of the depth of myometrial invasion, stromal invasion of cevix, lymphatic & pelvic metastases and extent of the lesion.

PURPOSE: This study was aimed to evaluate the recurrence rate of a giant cell tumor (GCT) of the bone. MATERIALS AND METHODS: The medical records of fifty four patients who were diagnosed with a giant cell tumor of the bone between March 1980 and December 2008 were analysed retrospectively. Among 54 patients, 27 were men, remaining 27 were women with the mean age of 33.1 years (range, 13-67 years). The mean duration of follow-up was 67.1 months. RESULTS: Twenty-one patients (38.9%) had a local recurrence. The mean time to recurrence was 21.5 months (range, 2-59 months). The local recurrence rate of the upper extremities was higher than that of lower extremities. According to Campanacci classification, patients with a grade I diseae had lower recurrence rate than those with grade II or III disease. There was no significant differences in the recurrence rates based on cryotherapy, the filling of bone cement or bone grafts and surgical margin. CONCLUSION: To prevent local recurrence of GCT of bone, curettage of the tumor and elimination of the remaining cells are more important than adjuvant therapy.

An attenuated classical swine fever virus (CSFV), Suri strain, is a va.iant derived from a vaccine virus, LOM strain. This study was performed to elucidate the molecular biologcal properties of CSFV Suri strain, and to obtain the basic data for molecular epidemiological approaches for the disease. The truncated form of gp55 gene without the C-terminal transmembrane domain, in size of 1,023bp, was amplified by RT-PCR and sequenced by dye terminator cyclic sequencing method, and inserted into BamHI site of pAcGP67B baculovirus vector, establishing a cloned pAcHEG plasmid. By the nucleotide sequences determined, 341 amino acid sequences were predicted. As compared the nucleotide and amino acid sequences of gp55 of Suri with the various CSFV, Suri strain showed the high homology over 99.1% with ALD and LOM strains, but comparably the lower homology with Alfort and Brescia. In comparison of amino acid sequence in variable domain of gp55 protein, the similar tendency of homology was observed. In hydrophobicity analysis, all of four CSFV strains revealed the analogous patterns of hydrophobicity. The numbers and locations of N-glycosylation site and cysteine residues in gp55 were analyzed, those of Suri strain being coincident with ALD and LOM strains. The results suggest that gp55 in Suri strain has the high similarity to those in ALD and LOM strains in terms of the nucleotide and amino acid sequences and the functional properties of gp55 protein..

PCR implication using the primers for gag, pol and rev genes in BLV (bovine leukemia virus) proviral DNA and syncytium assay were carried out for the Korean native goats experimentally infected with bovine leukemia virus to investigate pathogenesis of BLV in the goats, and to establish a model animal for BLV infection. The oligonucleotide primers used in PCR revealed very high specificity, The minimal amount of FLK-BLV cellular chromosomal DNA to detect the integrated BLV proviral DNA was 10 ng. The peripheral blood lymphocytes from the goat infected with BLV were examined at regular intervals by PCR amplification and syncytium assay. Pol or gag genes were detected in none of three infected goats at the 1st week post-infection (p.i.). At the 4th week p.i., one of three goats showed the amplified gag gene. Thereafter detection rates for the genes were increased, indicating that the BLV proviral genes were integrated in all of the lymphocytes from three goats, at the 16th weeks p.i., when it was evident in syncytium assay that the lymphocytes from all of three goats were infested with infective BLV. Investigating the tissues from the necropsied goats at the 8th month p.i., the amplified BLV proviral genes and infective BLV were detected in all of the peripheral lymphocytes from three infected-goats. Among various tissues examined, the amplified BLV proviral genes were observed in spleen and superficial cervical, mandibular and retropharyngeal lymph nodes, and the infective BLV, in superficial cervical and mandibular lymph nodes. It was assumed that the Korean native goat was quite susceptible to BLV infection, indicating that the goat could be a good model animal for BLV.

PURPOSE: This study was undertaken to evaluate how well anorectal manometry diagnose anal sphincter injury, especially with regard to the parameter of radial asymmetry. METHODS: Anorectal manometry were performed in 27 male patients with anal fistula of transsphincteric type. The postoperative values of each manometric parameter including radial asymmetry (RA) were compared with preoperative ones. And also, the association between the sites of functional defect assessed by cross-sectional pressure data under station pull-through (SPT) technique and those of anatomical defect made by fistulotomy operation were determined. RESULTS: Under rapid pull-through (RPT) technique, maximum resting pressure (MRP); 113.1 21.3 mmHg (preoperative value) vs 68.0 18.5 mmHg (p=.000) (postoperative value), RA of MRP; 16.7 3.7% vs 24.1 7.5% (p=.002), Maximum squeeze pressures (MSP); 199.0 35.2 mmHg, 169.6 48.7 mmHg (p=.006), RA of MSP; 15.5 3.7%, 22.8 3.5% (p=.000). Under SPT technique, MRP; 100.4 39.5 mmHg vs 71.2 34.6 mmHg (p=.000), RA of MRP; 16.3 7.9% vs 24.2 10.8% (p=.026), MSP; 299.1 71.6 mmHg vs 231.4 90.3 mmHg (p=.004), RA of MSP; 13.0 6.1% vs 22.0 8.4% (p=.001). Sites of functional defects interpreted upon SPT data were coincidental with sites of anatomical defects made by fistulotomy in 88.9% (MRP) and 92.6% (MSP) of cases. CONCLUSIONS: Manometric radial asymmetry could be a useful parameter in diagnosing anal sphincter injury and locating the site of defect.

We have recently experienced a case of cysticercosis treated with praziquantel. The patient, 22-year-old female, with 43 cystic masses had marked clinical response to the administration of praziquantel (75 mg/kg/day) for 7 days. It seems that praziquantel, anticestodal agent, might be a safe and effective therapy for this infection.

Increased death rate resulted from cardiovascular disease called for the study on the autonomic nervous system and cardiovascular system. It is known that an HRV (heart rate variability) spectrum analysis based on ECG (electrocardiograph) signals could be used to define activity of sympathetic and parasympathetic nervous system noninvasively. However, it is important to prove whether suggested HRV analysis method could provide the useful information for observing autonomic nervous system quantitatively and objectively before clinical application. In this study, 14 rats were used and divided into two groups, sympathectomy group and vagotomy group, respectively. During the experiment, ECGs of rats were collected three times at each experimental condition. After the application of Berger's series algorithm to the ECG raw data, HRV spectrum was obtained via FFT (fast Fourier transform). Power contents for each frequency bands were calculated from HRV waveforms. Two peak values, HF (high frequency) and LF(low frequency), representing autonomic nervous system status were used to extract the parameter, HF/LF ratio. Results showed that HF/LF values were increased for the sympathectomy group and decreased for the vagotomy group. It implies that the variations in HF/LF components exhibits the information for the classification of ANS(autonomic nervous system) function quantitatively. HRV analysis algorithm developed from this study could be expanded for the observation of autonomic nervous system variations in human.

OBJECTIVE: This study aimed to propose clinical guidelines for placing miniscrew implants using the results obtained from 3-dimensional analysis of maxillary anterior interdental alveolar bone by cone-beam computed tomography (CBCT). METHODS: By using CBCT data from 52 adult patients (17 men and 35 women; mean age, 27.9 years), alveolar bone were measured in 3 regions: between the maxillary central incisors (U1-U1), between the maxillary central incisor and maxillary lateral incisor (U1-U2), and between the maxillary lateral incisor and the canine (U2-U3). Cortical bone thickness, labio-palatal thickness, and interdental root distance were measured at 4 mm, 6 mm, and 8 mm apical to the interdental cementoenamel junction (ICEJ). RESULTS: The cortical bone thickness significantly increased from the U1-U1 region to the U2-U3 region (p < 0.05). The labio-palatal thickness was significantly less in the U1-U1 region (p < 0.05), and the interdental root distance was significantly less in the U1-U2 region (p < 0.05). CONCLUSIONS: The results of this study suggest that the interdental root regions U2-U3 and U1-U1 are the best sites for placing miniscrew implants into maxillary anterior alveolar bone.
