Synovial chondromatosis is an uncommon disorder characterized by metaplastic formation of multiple cartilaginous and osteocartilaginous nodules within connective tissue of the synovial membrane of joints. Osteochondroma is a benign lesion of osseous and cartilagenous origin. It is frequently found in the general skeleton, but is rare in the mandibular condyle. We experienced 2 patients with abnormal appearance of temporomandibular joint. Histologic diagnoses were not obtained, because surgery was unwarranted in view of the lack of symptoms and the benign differential diagnosis. We describes 2 cases that show the characteristics of both disease simultaneously.

PURPOSE: This study aimed to provide comparative measurements of the effective dose from direct and indirect digital panoramic units according to phantoms and exposure parameters. MATERIALS AND METHODS: Dose measurements were carried out using a head phantom representing an average man (175 cm tall, 73.5 kg male) and a limbless whole body phantom representing an average woman (155 cm tall, 50 kg female). Lithium fluoride thermoluminescent dosimeter (TLD) chips were used for the dosimeter. Two direct and 2 indirect digital panoramic units were evaluated in this study. Effective doses were derived using 2007 International Commission on Radiological Protection (ICRP) recommendations. RESULTS: The effective doses of the 4 digital panoramic units ranged between 8.9 microSv and 37.8 microSv. By using the head phantom, the effective doses from the direct digital panoramic units (37.8 microSv, 27.6 microSv) were higher than those from the indirect units (8.9 microSv, 15.9 microSv). The same panoramic unit showed the difference in effective doses according to the gender of the phantom, numbers and locations of TLDs, and kVp. CONCLUSION: To reasonably assess the radiation risk from various dental radiographic units, the effective doses should be obtained with the same numbers and locations of TLDs, and with standard hospital exposure. After that, it is necessary to survey the effective doses from various dental radiographic units according to the gender with the corresponding phantom.

OBJECTIVE: To analyze the methylenetetrahydrofolate reductase (MTHFR) mutation in patients with recurrent spontaneous abortion. MATERIAL AND METHOD: The blood samples of patients with recurrent spontaneous abortion were tested by PCR-RFLP method. RESULTS: Of 51 cases of study group, 14 (27.5%) were normal, 25 (49.0%) were heterozygosity, and 12 (23.5%) were homozygosity. Of 58 cases of control group, 20 (34.5%) were normal, 30 (51.7%) were heterozygosity, and 8 (13.8%) were homozygosity. But the difference between two groups was not significant (p=0.190). CONCLUSION: Hyperhomocysteinemia due to MTHFR mutation is a cause of recurrent spontaneous abortion. Therefore, the study for MTHFR mutation should be included in the workup of recurrent spontaneous abortion.

Plasma cholesterol is increased in normal aging in both rodents and humans. This is associated with reduced elimination of cholesterol and decreased receptor-mediated clearance of plasma low-density lipoprotein (LDL) cholesterol. The aims of this study were: (1) to determine age-related changes in plasma lipid profiles, and (2) to determine the effect of fenofibrate, an activator of peroxisome proliferator activated receptor alpha (PPAR alpha), on plasma lipid profiles in normal rats on a standard diet. Male Sprague-Dawley (SD) rats (n=15) were fed standard chow and water from 10 to 25 weeks of age. During that period, we measured daily food intake, body weight, fasting and random blood glucose levels, plasma total cholesterol (TC), triglycerides (TG), and free fatty acid (FFA) levels. At 20 weeks of age, all rats were randomly divided into two groups: a fenofibrate group (in which rats were gavaged with 300 mg/kg/day of fenofibrate) and a control group (gavaged with water). Fenofibrate treatment lasted 5 weeks. There were no significant changes in daily food intake, blood glucose, and plasma TG level with age. Body weight, plasma TC, and FFA levels were significantly increased with age. Fenofibrate significantly decreased plasma concentrations of TC and FFA, which had been increased with age. However, fenofibrate did not influence the plasma concentration of TG, which had not increased with age. These results suggest that fenofibrate might have a novel role in preventing age-related hypercholesterolemia in SD rats on a normal diet.

PURPOSE: The purpose of this study is to evaluate imaging and histopathologic findings including the immunohistochemical characteristics of invasive micropapillary carcinoma (IMPC) of the breast. METHODS: Twenty-nine patients diagnosed with IMPC were included in the present study. Mammographic, sonographic, and magnetic resonance imaging (MRI) findings were analyzed retrospectively according to the American College of Radiology Breast Imaging Reporting and Data System lexicon. 18F-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) findings were also evaluated. Microscopic slides of surgical specimens were reviewed in consensus by two pathologists with a specialty in breast pathology. RESULTS: Most IMPCs presented as a high density irregular mass with a non-circumscribed margin associated with microcalcifications on mammography, as an irregular hypoechoic mass with a spiculated margin on ultrasound, and as irregular spiculated masses with washout patterns on MRI. PET-CT showed a high maximum standardized uptake value (SUVmax) (mean, 11.2). Axillary nodal metastases were identified in 65.5% of the patients. Immunohistochemical studies showed high positivities for estrogen receptor and c-erbB-2 (93.1% and 51.7micro, respectively). CONCLUSION: Even though the imaging characteristics of IMPCs are not distinguishable from typical invasive ductal carcinomas, this tumor type frequently results in nodal metastases and high positivities for both estrogen receptor and c-erbB-2. The high SUVmax value that is apparent on PET-CT might be helpful in the diagnosis of IMPC.

BACKGROUND: It has been suggested that all components of the renin-angiotensin-aldosterone system (RAAS) are present in the vascular wall and that the vascular RAAS modulates vascular tone and vascular hypertrophy. One of the catalytic step in the RAAS cascade is the local conversion of angiotensin I to angiotensin II (Ang II) by angiotensin converting enzyme (ACE). One of the major sources of ACE in the vasculature is vascular smooth muscle cells (VSMC). Here, we provide insight into the intrinsic mechanisms by which the components of RAAS regulate gene expression of ACE in cultured smooth muscle cells of the rat and we also investigated the effects of cytokines on ACE mRNA. METHODS: RNA was extracted from the primary cultured VSMCs. We analyzed the expression levels of ACE by competitive reverse transcription-PCR using recombinant RNA as an internal standard. RESULTS: 1) ACE mRNA level was increased markedly by aldosterone in a dose- and time-dependent manner, indicating that there exists positive feedback mechanism within RAAS. 2) The induction of ACE mRNA by aldosterone was inhibited by spironolactone. 3) Aldosterone-stimulated expression of ACE was also inhibited by Ang II, which shows that Ang II acts as a negative regulator of the expression of ACE in RAAS cascade. 4) Interleukin-1beta or TNF-alpha did not induce ACE mRNA expression. 5) However, mixture of interleukin-1betaand TNF-alpha(CytoMix) significantly increased the expression of ACE. It was also shown that CytoMix increased aldosterone-stimulated ACE mRNA expression in an additative manner. CONCLUSION: These results indicate that the expression of ACE in smooth muscle cells is modulated by the components of RAAS and cytokines. The intrinsic positive and negative feedback controls of RAAS would play an important role in the pathogenesis of vascular diseases.

PURPOSE: To evaluate the relative value of arterial, portal and delayed phase images in the measurement of hepatic metastatic mass arising from gastrointestinal malignant tumor using spiral CT. MATERIALS AND METHODS: Thirty-three with 45 metastatic tumors of the liver underwent tri-phasic spiral CT. For this purpose one or two lesions were chosen in each patient whose primary tumor was shown to be stomach cancer(n=15), colon cancer(n=16), or ileal cancer(n=1). Tumor size ranged from 1 to 12.2 (mean, 4.3)cm. Arterial, portal and delayed phase images were obtained at 30 -35 seconds, 70 -75 seconds, and 3 minutes, respectively, after the injection of contrast materials. Using a work station, two radiologists independently measured the longest diameter of the selected lesions, and a second measurement was taken three days later. Contrast, as well as intra-and interbserver differences among the three phases, was statistically analysed. RESULTS: Intra- and interobserver difference were, espectively, 2.3 and 3.8 mm during the portal phase; 3.3 and 4.6 mm during the arterial phase; and 2.9 and 4.5 mm during the delayed phase. ANOVA with Tukey's multiple comparison showed that none of these differences were statistically significant. Contrast between mass and liver parenchyma was especially clear during the portal phase (p=0.0001, using the Kruskal-Wallis CONCLUSION: Intra- and interobserver differences in the measurement of hepatic metastatic tumors were statistically insignificant during all three phases. The least difference and best contrast were seen during the portal phase.
