PURPOSE: To compare the characteristic MR findings of infectious sacroiliitis (IS) and ankylosing spondylitis(AS). MATERIALS AND METHODS: We retrospectively reviewed MR findings in eight patients with IS (pyogenic in six, tuberculosis in two) confirmed by culture and clinical follow-up, and in six with AS by HLA-B27 typing. A control group of 13 asymptomatic volunteers was formed, and they underwent MRI. Findings were analysed for morphology, degree of bone erosion, and adjacent soft tissue change. CT findings of AS in four patients and IS in four were also compared to MR findings. RESULTS: MR characteristics of IS included unilaterality (100 %), abnormal cartilage signal intensity (100 %), bone marrow change (100 %), contrast enhancement (100 %), erosion (63 %), and soft tissue change (63 %). MR findings of AS showed bilaterality (67 %), abnormal cartilage signal intensity (80%), bone marrow change (80 %), erosion (80 %), contrast enhancement (44 %) and soft tissue change (10 %). CT scan showed bony sclerosis and erosion (86 %), and abnormal joint space (71 %). CONCLUSION: MR findings of sacroiliitis were loss of thin zone of a cartilage and erosions on T1-weighted image, and increased signal intensity on T2-weighted image. MRI is regarded as a useful diagnostic method where conventional diagnosis is difficult, and is able to image cartilage abnormalities directly and noninvasively. Significant differences in MR findings between IS and AS were not noted, however.

OBJECTIVE: To evaluate whether co-culture of oocytes on vero cell monolayers from Day 0 (Day 0 group) after egg retrieval results in an increase in developmental capacity such as fertilization rate, embryo quality, blastulation and clinical pregnancy rate compared with co-culture of oocytes from Day 1 (Day 1 group). METHODS: Sperms were treated with Hams F-10 supplemented with 10% human follicular fluid (hFF). Vero cells for co-culture were prepared in TCM-199 with 10% FBS. Oocytes were co-cultured from Day 0 and fertilized oocytes were co-cultured from Day 1 on vero cell monolayers in DMEM with 10% and 20% hFF, respectively after egg retrieval. On day 1, 2 and 5, fertilization rate and grade of embryos and blastocysts were evaluated. Results (fertilization rate, cleavage rate, grade of embryos and blastocysts and pregnancy rate) were considered statistically significant when p value was less than 0.05 using t-test and ci2. RESULTS: In sibling oocytes of same cycles, no differences were found in fertilization rate (94.6 vs. 91.4%), cleavage rates (94.6 vs. 91.4%), embryo grade (on day 2 and 3) and blastulation (65.6 vs. 57.0%) and their grade. In different oocytes of different cycles (patients), no differences were found in fertilization (79.8 vs. 78.3%), cleavage rates (77.7 vs. 76.4%) and blastulation (56.0 vs. 45.3%), but pregnancy rate was higher in the Day 0 group than in the Day 1 group (60.0 vs. 42.9%). CONCLUSIONS: This study revealed that the embryonic development capacities were not affected by the different co-culture time in the sibling oocytes of same cycles. Although no statistical significance, because of small size of study, there was a trend for higher pregnancy rates in Day 0 group compared to Day 1 group in different oocytes of different cycles.

OBJECTIVES: Urinary hippuric acid levels have been usually determined to ' evaluate workers exposed to toluene. Food and drink intake could affect urinary hippuric acid excretion and this study was carried out to investigate what kinds of food and drink would affect urinary hippuric acid excretion. METHODS: The subjects were 136 medical school students. Authors measured urinary hippuric acid levels three times from 10 a. m. to noon; before, one hour after and two hours after food or drink-intake, and they were asked not to eat from the previous night (9 p. m) of testing. We selected six diets (bread and coffee, brown sauce noodle, Korean style meal, noodle, pork'galbi and rice and soybean stew and rice), six fruits (apple, grape, orange, pear, persimmon and plum) and five beverages (Alps-D(R), Demisoda(R), Orange juice(R), Pear juice(R) and Pocari sweat(R)). Analysis of urinary hippuric acid was performed by high performance liquid chromatography. RESULTS: Intake of popular Korean diets, fruits and some drinks didn' t affect urinary hippuric acid excretion. But intake of sodium benzoate-contained Alps-D(R) increased urinary hippuric acid excretion. CONCLUSIONS: For the health examination on workers exposed to toluene, the history of diet and fruit intake can be negligible, but that of beverage intake should be included.

PURPOSE: Diallyl disulfide (DADS), an organosulfur compound in garlic, has been reported to be effective in inhibiting the growth of several human tumor cell lines. The aim of this study was to determine whether DADS induced growth inhibition in MCF-7 breast cancer cell lines and to understand the molecular mechanism by which DADS acts. METHODS: MCF-7 cell lines were incubated with various concentrations of DADS for various time intervals and the cytotoxicity was determined by MTT assay. We examined the changes of intracellular proteins related to apoptosis, such as bcl-2, bax and PARP in cells treated with DADS. To study the expression level of bcl-2 and bax, which serve as modulators of apoptosis, we performed RT-PCR and western blot analysis. RESULTS: MCF-7 cells treated with DADS led to the suppression of viability and proliferation in both a time and concentration dependent manner. Microscopic observation revealed typical features of apoptosis in the DADS-treated cells, further verified in nuclear DAPI staining. Flow cyto-metry analysis with FITC-annexinV and propidium iodide (PI) demonstrated that the apoptotic cell population with AnnexinV+/PI- increased dramatically from ~0.8% to ~75% after 24h exposure to 500 microM DADS in MCF-7 cells. Cell cycle analysis demonstrated that the number of apoptotic cells increased with the increasing time of the DADS treatment. Additionally, thermore, we investigated the effects of DADS on apoptosis related gene expression in MCF-7 cells. PARP cleavage was markedly increased in the DADS treated cells with time. This result indicated that DADS induced the caspase-dependent apoptotic pathway. We also found down-regulation of bcl-2, however no significant change of Bax expression was observed after DADS treatment. Conclusion: Taken together, these results indicate that DADS induces apoptosis by activating a caspase pathway involving the activation of Bcl-2 but not of Bax. Our findings suggest chemotherapeutic potentials of DADS in human breast cancer.

PURPOSE: Administration of antiretroviral drugs to mothers and infants significantly decreases mother-to-child human immunodeficiency virus (HIV) transmission; cesarean sections and discouraging breastfeeding further decreases this risk. The present study confirmed the HIV status of babies born to mothers infected with HIV and describes the characteristics of babies and mothers who received preventive treatment. METHODS: This study retrospectively analyzed medical records of nine infants and their mothers positive for HIV who gave birth at Korea University Ansan Hospital, between June 1, 2003, and May 31, 2013. Maternal parameters, including HIV diagnosis date, CD4+ count, and HIV ribonucleic acid (RNA) copy number, were analyzed. Infant growth and development, HIV RNA copy number, and HIV antigen/antibody test results were analyzed. RESULTS: Eight HIV-positive mothers delivered nine babies; all the infants received antiretroviral therapy. Three (37.5%) and five mothers (62.5%) were administered single- and multidrug therapy, respectively. Intravenous zidovudine was administered to four infants (50%) at birth. Breastfeeding was discouraged for all the infants. All the infants were negative for HIV, although two were lost to follow-up. Third trimester maternal viral copy numbers were less than 1,000 copies/mL with a median CD4+ count of 325/microL (92-729/microL). Among the nine infants, two were preterm (22.2%) and three had low birth weights (33.3%). CONCLUSION: This study concludes that prophylactic antiretroviral therapy, scheduled cesarean section, and prohibition of breastfeeding considerably decrease mother-to-child HIV transmission. Because the number of infants infected via mother-to-child transmission may be increasing, studies in additional regions using more variables are necessary.

BACKGROUND: Anaphylaxis is a systematic allergic reaction, which may be fatal. However, despite its seriousness, its low level of incidence has prevented in depth studies. Thus, we analyzed the causes of anaphylactic shock in patients admitted in a tertiary hospital, observed its clinical symptoms, and formed a basis for adequate emergency treatment, as well preventive methods. METHODS: The patients who visited Ajou university hospitals from June 1994 to May 2000(7 years) and who met the 1974 JAMA definition were selected for this retrospective study. The analysis of causative agents was made on the basis of clinical symptoms and the patients' chief complaints at the time of admission. Patients diagnosed with anaphylactic shock included those showing at least two types of IgEmediated symptoms; and those with a simple rash or breathing difficulties were excluded from the study. RESULTS: Of 36 patients, 22 were male and 14 female, Those below the age of 20 comprised 16.7% of the patients(6 patients), between 20 and 29 comprised 16.7%(6 patients), 30 and 39 comprised 25%(9 patients), 40 and 49 comprised 27.8%(10 patients), over 50 comprised 14%(5 patients). The overall percentage show 70% of the patients in active adult age group. Rash was the most common clinical symptoms(89%, 32 patients) and hypotension the second(75%, 27 patients), followed by respiratory distress, fainting, and arrhythmia. Causative agents were insect bites, including bee stings(15 patients), medication(12 patients), food(8 patients), and unknown(1 patients). Nine(9) of the 36 case, were diagnosed as having an atopic origin. CONCLUSION: Bee sting was the single most common cause in the insect criteria while penicillin and NSAIDs accounted for most of medication-induced cases. Food showed a varied distribution. An atopic origin was not a basis for anaphylactic shock, but did show a two-fold increase of prevalence. This study is the first of its kind in addressing anaphylactic shock, a potentially severe illness, over a period of 7 years.

Giant cell tumor of the tendon sheath(GCTTS) is a benign condition which involves the synovium of the tendonsheaths, and usually occurs around the small joints, e. g. the ankle, knee, and wrist. Histologically, GCTTS is similar to pigmented villonodular synovitis(PVNS). The authors report MRI findings of a GCTTS. This showed lower signal-intensity lesions than adjacent muscles on T1-weighted, proton density weighted, and T2-weighted images.

PURPOSE: To estimate the number of cancer cases during 2002 in Korea through a nationwide hospital based cancer registration by the Korea Central Cancer Registry (KCCR). MATERIALS AND METHODS: One hundred and thirty nine hospitals participated in the KCCR program in 2002. Cancer cases were coded and classified according to the International Classification of Diseases for Oncology 2nd edition (ICD-O-2). The software program `IARC Check' was used to evaluate the quality of registered cancer cases. Of the 122, 770 malignancies registered, 11, 732 (9.6%) duplicated malignancies were excluded. Among the remaining 102, 677 malignancies, 3, 652 (3.6%) cases with carcinoma in situ (Morphology code/2) were separated. Finally, 99, 025 malignancies were analyzed. RESULTS: Of the total of 99, 025 malignancies, 55, 398 (55.9%) cases were males and 43, 627 (44.1%) were females. More than one third of cases were from the elderly (65 years old and more). The six leading primary cancer sites in the order of their relative frequency, were stomach (24.0%), followed by the lung (16.0%), the liver (15.4%), the colorectum (11.6%), the bladder (3.2%), and the prostate (3.0%) among males. In females, the breast (16.8%) was the common cancer site, followed by the stomach (15.3%), the colorectum (10.7%), the thyroid gland (9.5%), the cervix uteri (9.1%), and the lung (6.6%). CONCLUSION: With the continued increase in cancer cases especially prostate cancer among males and thyroid cancer among females, the total number of registered cancer cases in Korea continues to rapidly increase.

PURPOSE: To evaluate the morphologic differential diagnosis of benign and malignant ductal breast tumors, as seen on US. MATERIALS AND METHODS: US findings in 29 pathologically proven cases of ductal breast tumor were retrospectively reviewed. All patients were female and their mean age was 42 years. Nineteen tumors were benign and ten were malignant, and all ductal or cystic lesions showed solid masses. According to the location of the mural nodule, we classified the sonographic appearance of these tumors into three types : intraductal, intracystic and amorphic. The intraductal type was divided into three subtypes: incompletely obstructive, completely obstructive and multiple mural nodules. For the intracystic type, too, three subtypes were designated : the intracystic mural nodule (mural cyst), intracystic mural nodule with the duct (mural cyst+duct) and intracystic multiple mural nodules. The amorphic type is defined as an atypical ductal tumor with the mural nodule extending into adjacent parenchyma. RESULTS: The margin of the duct or cyst was smooth in 68.4% of benign, and irregular in 90% of malignant ductal tumors. Internal echogeneity of the duct or cyst usually showed homogeneity in both benign and malignant tumors. 73.7% of tumors connecting the duct were benign and 50% were malignant. In benign tumors, 52.6% of mural nodule had an irregular margin, while in malignant tumors, the corresponding proportion was 100% ; both types usually showed heterogeneous hypoechogeneity. Among benign tumors, the most common morphologic type was the intraductal incompletely obstructive subtype (36.8%) ; among those that were malignant, the amorphic type was most common, accounting for 40% of tumors. No amorphic type was benign and no incompletely obstructive subtype was malignant. CONCLUSION: When ductal breast tumors are morphologically classified on the basis of sonographic findings, the intraductal incompletely obstructive subtype suggests benignancy, and the amorphic type, malignancy. The morphologic classification of ductal breast tumors based on sonography is therefore useful for the differential diagnosis of benignancy and malignancy.
