This study was conducted to assess the prognostic value of tumor angiogenesis and Cathepsin-D in breast carcinoma, by correlating them with other clinicopathologic prognostic factors. In order to estimate microvessels within the tumor, an immunohistochemical method using monoclonal antibodies for factor VIII-related antigens (DAKO-vWf, F8/86) was used, and they were counted (perx200 field) in the most active areas of neovascularization. For the expression of Cathepsin-D, an immunohistochemical method using monoclonal antibodies (Novocastra, NCL-CDm) was performed. The microvessel count ranged from 8 to 346 per x200 field and the mean (+/-SD) was 72.46+/-54.96. The microvessel count was correlated with the estrogen receptor status, and it was also correlated with the tumor size when it was graded into four groups (1-33, 34-67, 68-100, >100), but was not correlated with other clinicopathologic parameters. Cathepsin-D was expressed in 40% (46/115) of the cases, but it was statistically correlated with the tumor size only. In conclusion, the expression of Cathepsin D and the degree of angiogenesis in breast cancer showed a correlation with the tumor size only. Therefore, they do not appear to be good prognostic parameters, according to the present study.

PURPOSE: The purpose of this study was to analyze the patterns of intervertebral disc enhancement seen in tuberculous and pyogenic spondylitis, and to evaluate their utility in differentiating between the two groups. MATERIALS AND METHODS: Magnetic resonance images obtained in 31 consecutive infectious spondylitis patients (43 discs) in whom intervention occurred due to infected vertebral bodies, were retrospectively analysed. Nineteen of the patients had tuberculosis and 12 were infected by pyogenic organisms. After analysis, the patterns of disc enhancement revealed by contrast-enhanced T1-weighted axial and sagittal MR imaging were classified as of four types: Type I, non-enhancing; Type II, enhancement of the peripheral margin of the disc; Type III, enhancement of the peripheral margin and central area adjacent to the cortical vertebral endplate; Type IV, general enhancement and/or destruction of the disc. RESULTS: There were 19 cases of tuberculous spondylitis involving 28 intervertebral discs, and the enhancement patterns observed were as follows: Type I: n=4, 14%, Type II: n=17, 61%, Type III: n=1, 4%, Type IV: n=6, 21%. Twelve cases of pyogenic spondylitis involved 15 intervertebral discs; the enhancement patterns observed in these cases were as follows: Type I: n=1, 7%, Type II: n=2, 13%, Type III: n=10, 67%, Type IV: n=2, 13%. CONCLUSION: Careful analysis of the patterns of disc enhancement occurring in infectious spondylitis can be useful for differentiating between the tuberculous and pyogenic varieties of this condition.

OBJECTIVES: The purpose of this study was to investigate the prevalence of musculoskeletal symptoms in oriental melon-growing farmers and to evaluate the ergonomic risk factors of melon cultivation. METHODS: The study included 217 subjects growing oriental melons mainly in 3 villages. Subjects were interviewed by means of a structured questionnaire. Instruments used the general features and symptom table of NIOSH to evaluate tasks using ergonomic tools (REBA, OWAS). RESULTS: A total of 202 final respondents answered. The prevalence of musculoskeletal symptoms based on the NIOSH standard criteria was 162 (75.2%). The prevalence per body part for lower back, knee and shoulder were 102 (50.5%), 86 (42.6%) and 71 (35.1%), respectively. The prevalence of pain complaints of the musculoskeletal symptom was 91 (45.0%). The prevalence of complaints per body part of lower back, knee and shoulder were 54 (26.7%), 41 (20.3%) and 37 (18.3%), respectively. Logistic regression analysis showed men were at higher risk compared to women (OR=2.409, 95% CI=1.071~5.389), and ore than 30 years of work having a higher risk compared to less than 30 years of work (OR=2.445, 95% CI=1.150~5.197). High risk tasks were moving around boxes and nursery plants for planting, transplanting nursery plants, and picking melons. CONCLUSIONS: Musculoskeletal symptoms were very highly prevalent in oriental melon-growing farmers, showing up in 75.2% of cases. They were exposed to ergonomic high risk factors such as squatting. These risk factors must be improved in some way.

OBJECTIVE: To compare the apparent diffusion coefficient (ADC) values of upper abdominal organs with 2 different 3.0 tesla MR systems and to investigate the usefulness of normalization using the spleen. MATERIALS AND METHODS: Forty-one patients were enrolled in this prospective study, of which, 35 patients (M:F, 27:8; mean age ± standard deviation, 62.3 ± 12.3 years) were finally analyzed. In addition to the routine liver MR protocol, single-shot spin-echo echo-planar diffusion-weighted imaging using b values of 0, 50, 400, and 800 s/mm2 in 2 different MR systems was performed. ADC values of the liver, spleen, pancreas, kidney and liver lesion (if present) were measured and analyzed. ADC values of the spleen were used for normalization. The Pearson correlation, Spearman correlation, paired sample t test, Wilcoxon signed rank test and Bland-Altman method were used for statistical analysis. RESULTS: For all anatomical regions and liver lesions, both non-normalized and normalized ADC values from 2 different MR systems showed significant correlations (r = 0.5196-0.8488). Non-normalized ADC values of both MR systems differed significantly in all anatomical regions and liver lesions (p < 0.001). However, the normalized ADC of all anatomical regions and liver lesions did not differ significantly (p = 0.065-0.661), with significantly lower coefficient of variance than that of non-normalized ADC (p < 0.009). CONCLUSION: Normalization of the abdominal ADC values using the spleen as a reference organ reduces differences between different MR systems, and could facilitate consistent use of ADC as an imaging biomarker for multi-center or longitudinal studies.

OBJECTIVE: The purpose of our study was to assess prevalence of carotid intraplaque hemorrhage (IPH) and associations between territorial acute infarction and IPH on magnetization-prepared rapid acquisition with gradient-echo (MPRAGE) in patients with acute neurologic symptoms. METHODS: 83 patients with suspected acute neurologic symptoms were evaluated with both brain diffusion weighted imaging (DWI) and carotid MPRAGE sequences. Carotid plaque with high signal intensity on MPRAGE of >200% that of adjacent muscle was categorized as IPH. We analyzed the prevalence of IPH and its correlation with territorial acute infarction. RESULTS: Of 166 arteries, 39 had a carotid artery plaque. Of these arteries, 26 had carotid artery stenosis less than 50%. In all carotid arteries, MR-depicted IPH was found in 7.2% (12/166). High-signal intensity on DWI was found in 17.5% (29/166). Combined lesion with ipsilateral high-signal intensity on DWI and IPH on carotid MPRAGE sequence was found in 6 lesions (6/166, 3.6%). Of patients with carotid artery plaque, MR-predicted IPH was found in 30.8% (12/39) and match lesions with high-signal intensity on DWI and MPRAGE was found in 15.4% (6/39). MR-predicted IPH was significantly higher prevalence in high-grade stenosis group (p=0.010). Relative risk between carotid MPRAGE-positive signal and ipsilateral high-signal intensity on DWI in arteries with carotid artery plaques was 6.8 (p=0.010). CONCLUSION: Carotid MPRAGE-positive signal in patients was associated with an increased risk of territorial acute infarction as detected objectively by brain DWI. The relative risk of stroke was increased in high-grade stenosis categories.

BACKGROUND: Allogeneic or autologous bone marrow transplantation (BMT) or peripheral blood stem cell transplantation (PBSCT) has been settled a modality of treatment in hematologic malignantdisorders or solid tumors. Because engraftment or not was important for the direction of treatment and prognosis of the patients, various methods, judging it early were groped. Instead of an absoluteneutrophil count (ANC) or platelet count in PB, we used reticulocyte parameters as early predictors of hematopoietic engraftment. METHODS: We measured the ANC with reticulocyte parameters daily in 25 patients receiving allogeneic BMT or PBSCT (n=17, 30.82+/-9.97 years old) and autologous PBSCT (n=8, 30.63+/-8.55 years old) from January 2002 to February 2003 in Kyungpook National University Hospital. Wedefined erythroid engraftment as the first day of a mean corpuscular volume of reticulocyte (MCVr)>or=105 fL and immature reticulocyte fraction (IRF) >or=10% in the second rising peak and myeloid engraftment as the first day of ANC >or=500/microL. RESULTS: The erythroid engraftment occurred after a mean time of 16.24+/-4.16 days in allogeneic graft and 14.00+/-3.55 days in autologous graft and the myeloid engraftment occurred 17.94+/-3.23 days and 15.00+/-2.78 days, respectively. In the allogeneic graft, the erythroid engraftment occurred earlier than the myeloid engraftment (P=0.03). In the autologous graft, the erythroid engraftment preceded the myeloid engraftment; however, it was not statistically significant (P=0.47). Among 3 cases, wherein the erythroid engraftment occurred later than the myeloid engraftment in allogeneic graft, 2cases were ABO-incompatible PBSCT. CONCLUSIONS: Considering that the successive increase of immature reticulocytes preceded that of ANC in most cases, we concluded that as an early indicator of hematopoietic engraftment, reticulocyte parameters such as IRF and MCVr were useful especially observing them simultaneously.

OBJECTIVE: To identify fetal gender using fetal DNA in maternal plasma. METHODS: DNA from maternal plasma of 55 pregnant women(47: inpatients, 8: outpatients) underwent a sensitive Y-PCR assay to identify gender. RESULTS: Of the inpatients, fetus-derived Y sequences were detected in 26(80.6%) of the 31 maternal plasma samples from women bearing male fetuses. None of the 16 women bearing female fetuses had positive results from plasma DNA. Eighteen weeks is earliest gestation of gender identification. Of the outpatients(GA 8-11 weeks), fetus-derived Y sequences were detected in 7 of the 8 maternal plasma. Only one patient's fetal gender(GA 9 weeks) was identified. The others were not identified at this moment. CONCLUSION: We identified fetal DNA in maternal plasma. The sensitivity of Y-PCR was 80.6% in women bearing male fetus and the specificity was 100% in women bearing female fetus.

BACKGROUND: Interleukin 31 (IL-31) is a T helper type 2 effector cytokine that plays an important role in the pathogenesis of atopic and allergic diseases. IL-31 may be involved in promoting allergic inflammation and in inducing airway epithelial responses such as allergic asthma. METHODS: Single-base extension analysis was used to detect the genotypes of IL-31 single nucleotide polymorphisms (SNPs), and we compared the genotype and allele frequencies of the IL-31 SNPs between patients with asthma and healthy controls. RESULTS: There were no significant differences in the genotype and allele frequencies of the IL-31 SNPs between patients with asthma and healthy controls. Furthermore we compared the genotype and allele frequencies of IL-31 SNPs between patients with atopic asthma, those with non-atopic asthma and healthy controls. This showed that the SNPs were not associated with the susceptibility to atopic asthma. There were no significant differences in the haplotype frequencies of IL-31 SNPs between patients with asthma and healthy controls. In patients with asthma, the IL-31 SNPs were significantly correlated with total serum levels of IgE (p=0.035). CONCLUSIONS: Our results indicate that, the IL-31 SNPs may be associated with IgE production in patients with asthma.
