Primary biliary cirrhosis is frequently associated with a variety of disorders presumed to be autoimmune in nature, such as Sjogrens syndrome, scleroderma, rheumatoid arthritis, systemic lupus erythematosus, and autoimmune thyroiditis. Scleroderma has been recognized in association with primary biliary cirrhosis. Most cases present as the CREST (calcinosis cutis, Raynauds phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) syndrome. Isolated pulmonary hypertension develops in a small proportion of patients, nearly all of whom have limited cutaneous involvement. We report a case who has diffuse scleroderma associated with primary biliary cirrhosis and isolated pulmonary hypertension.

Intraspinal neurenteric cysts are rare congenital lesions that results from abnormal separation of germ layers in the third week of embryonic development, which may cause spinal compression. Although, the diagnosis of neurenteric cyst was very difficult prior to operation, MRI has proven to be a useful imaging modality in detection, localization and characterization of intraspinal neurenteric cysts. We recently experienced intraspinal neurenteric cyst in two patients who presented with progerssive quadriparesis. Myelography, CT myelography and MRI were taken and complete excision was performed. The MRI findings are presented and the literature is reviewed.

PURPOSE: A common finding of carotid artery on magnetic resonance angiograms(MRAs) is a signal dropout along the posterior wall of carotid bulb due to reverse flow. The purpose of this study is to evaluate variable flow patterns on bifurcated carotid arterial phantoms using steady-state flow. MATERIALS AND METHODS: We designed phantoms of a bifurcated carotid artery with acrylic materials. Flow patterns were evaluated with axial and coronal imaging of MRA(2D-TOF, 3D-TOF), color Doppler imaging, and computational fluid dynamics (CFD) within the phantoms constructed of an automated closed-type circulatory system filled with 4% sugar solution. These findings were compared with findings obtained from normal volunteers. RESULTS: Axial 3D-TOF MRA images exhibited closer resemblance to the contour of the inner wall of phantoms when compared to coronal 2D-TOF MRA imaging. However, 2D-TOF MRA showed good contrast difference of signal intensities between forward flow area and reverse flow area. Dark zones with reduced signal intensities due to reversed flow were separated from the outer wall of the internal and external carotid arteries by a thin layer of forward flow along the wall on the source slice image of MRA. The general hemodynamics of the phantoms on MRA were identical to hemodynamics on color Doppler imaging and CFD. The results obtained with the phantoms matched the findings on normal volunteers. CONCLUSION: Although representations of bifurcated carotid arterial phantoms on axial 3D-TOF MRA were excellent if ideally desinged, the zone of reversed flow could be a significant factor in creating distorted image when the zone of reversed flow contacted directly with curved or deformed arterial wall.

The authors analysed the CT findings in 75 cases diagnosed as gastric carcinoma by U.G. I.S. or endoscopy in a 3)1, year period. The comparative analysis betw~en CT findings and surgical pathologic findings was done in 55 cases who underwent surgery. 20 cases could not be operated upon because of distant metastasis. The gastric carcinoma was devided into 4′ stages according to the staging system of the American joint Committee on Cancer. The CT findings were then compared and the following results noted : 1. The relationship with gastric wall thickening and penetratioil degree of tumori no thickening (Iesser than 1.0 cm) of 3 cases showed all of T1, 11 of localized thickening (1. 0.1 .5cm) showed 7 of T2, 38 of localized thickening (more than 1.5 cm) showed 37 of T3 and 3 of diffuse thickening showed all of T4a. 2. The accuracy of Iymph node detection by CT scan, 1) Regionaf tymph node showed 86% in operative f in ding and 73% in pathologic. 2) Extragastric Iymph node showed 87% in operative finding and 89% in pathologic. 3) Retro-peritoneallymph node showed 96% in operative finding and 95% in pathologic. ic. 3. In operated cases, there was one case of false positive distant metastasis and three false negative cases. 20 cases of non-operated cases showed distant metastasis such as liver, lung or kidney. 4. 55 cases were classified as stage 1 in 4 cases, 11 in 18, 111 in 23 and IV in 10 by pathologic findings, and 1 in 3, 11 in 24, 111 in 19 and IV in 9 by CT. The overall accuracy by CT stagi ng is 75%. 5. Among a total of 75 cases, there were 46 operable cases by CT finding an d 43 operabl e cases by pathologic staging. There we re 29 inoperable cases by CT finding and 27 cases by pathologic staging. Therefore, there was a 93% overall accuracy by CT stagi ng in terms of determination of operability. 6. The accuracy of adhesion into adjacent structure by CT finding was 69%. compared with operable finding.

Although crystalloid solutions such as Ringer's lactate have become the standard for initial volume replacement after hemorrhage, it is controversy whether this fluid alone restores and maintains the depressed physiologic function after severe hemorrhage. Six anesthetized dogs were bled(35ml/kg) and resuscitated with Ringers lactate solution (100 ml/kg). Physiologic variables are measured initialy, after hemorrhage, after resucitation. Compared with initial value, after resuscitation data show marked reduction in hemoglobin, oxygen carrying capacity, vascular resistance, and electrolyte. But cardiac output and blood gas analysis data was not changed. Prothrombin time and partial thromboplastin time was prolongated. From this study crystalloid resuscitation in severe hemorrhagic shock restore cardiac output and perfusion, but fail to maintain adequate oxygen carrying capacity.

PURPOSE: Neuroendocrine differentiation and expression of drug resistance may affect the response to chemotherapy and the prognosis of advanced non-small cell lung cancer. We conducted retrospective study to evaluate the possibilities of neuroendocrine differentiation and drug resistance markers being used as prognostic factors in patients with non-small cell lung cancer. MATERIAL AND METHOD: Immunohistochemical staining of NSE, PgP and GST-pai with polyclonal antibodies in pathologic specimens of 47 patients with non-small cell lung cancer were done. The relationship between the expression of the markers and the response to cisplatin-based chemotherapy and the overall survival were assessed. RESULTS: NSE staining was positive in 17% and there was no difference between adenocarcinoma and squamous cell carcinoma. NSE positive patients showed increased response rate (63% vs 26%, p=0.049) and prolonged response duration (15.8mo vs 4.5mo, p=0.0007). But there was no difference in overall survival between NSE positive and negative groups. The PgP positive rate was 17% and GST-pai positive rate was 47%. No correlations were found among the expression of drug resistance, the sensitivity to chemotherapy and overall survival. CONCLUSION: Patients with non-small cell lung cancer with positive NSE showed increased response rate to chemotherapy and prolonged response duration but overall survival was not related to NSE expression. Expression of PgP and GST- were not important in predicting the prognosis in non-small cell lung cancer.

Cancer Research and Treatment 2005;37(2):103-108
PURPOSE: The purpose of this study was to evaluate the clinicopathological significance of the microvessel density and macrophage and mast cell counts in invasive breast carcinomas. MATERIALS AND METHODS: 45 invasive breast carcinomas were immunohistochemically stained with the endothelial antigen, CD34, and macrophage marker, CD68. 0.1% toluidine blue was used to highlight mast cells. The microvessel and mast cell counts were performed at x200 magnification and the macrophages at x400 magnification. RESULTS: With the 45 invasive breast carcinomas, there were no statistically significant associations between the mast cell, macrophage and microvessel counts and the tumor size and lymph node status. ER and PR negative mast cells infiltrated more than in cases of positive stati, with statistical significance (p-value=0.010 and 0.005, respectively). The macrophage counts were negatively correlated with the PR status (p-value=0.030). With respect to the c-erbB-2 status, there was no significance correlation with the mast cell, macrophage and microvessel counts. The mast cell counts showed significantly positive correlation with the microvessel counts in the invasive breast carcinomas (p-value=0.015). In a comparison of the macrophage counts with the microvessel counts, a positive tendency for both parameters, but without statistical significance (p-value=0.310). CONCLUSION: Increasing numbers of mast cells and macrophages were recruited in invasive breast carcinomas, which contribute to angiogenesis. The microvessel density in invasive breast carcinomas had no statistically significant association with the tumor size, lymph node status, and histological grade, presence of DCIS component, estrogen/progesterone receptor status and cerbB-2 status. The evaluation of angiogenesis using these methods is not thought to provide an independent clinicopathological factor in invasive breast carcinomas.
