The chick embryo chorioallantoic membrane in the study of tumor angiogenesis D. Ribatti The chick embryo chorioallantoic membrane CAM is commonly used as an experimental in vivo assay to study both angiogenesis and antiangiogenesis in response to tissues, cells or soluble factors. This article summarizes literature data about the use of the CAM in the study of tumor angiogenesis and particularly our experimental data concerning the study of angiogenesis in multiple myeloma and in neuroblastoma.

Immunohistochemical evaluation of the tumor neoangiogenesis as a prognostic factor for gastric cancers Daniela Lazăr, Sorina Tăban, M. Raica, I.

Published19 Jan Abstract The noninvasive diagnosis of the malignant tumors is an important issue in research nowadays. Our purpose is to elaborate computerized, texture-based methods for performing computer-aided characterization and automatic diagnosis of these tumors, using only the information from ultrasound images.

We evaluated the relation between MVD, the VEGF expression, the clinicopathologic factors and the survival in patients with gastric cancer. A prospective study has been carried out, regarding the evolution and aggressiveness of the gastric cancer, with a duration of 5 years, 61 patients that underwent a surgery for gastric cancer being included in the study. The immunohistochemical reactions for CD34 and VEGF were performed for all gastric cancers cases included in the study group.

MVD has shown in the gastric carcinomas an average value significantly higher in comparison to the normal mucosa The angiogenesis in colorectal carcinomas with and without lymph node metastases Simona Gurzu, J. Jung, L. Azamfirei, T. Mezei, Anca Maria Cîmpean, Z. Szentirmay Many clinical trials revealed that the anti-angiogenic treatment could improve prognosis in patients with metastatic colorectal carcinomas CRCwhen added to standard chemotherapy.

In this paper, we tried to find out if the microvascular density MVD determined with CD31, CD was correlated with lymph papilloma dotto seno status, and if the intensity of angiogenesis was different in right versus abdominal cancer mri colon segments.

We studied CRC, with and without lymph node metastases, from left and 59 from right colon. In the right colon, the MVD was higher in the cases where the lymph nodes did not present metastases pN0 but also when four or more lymph nodes were involved pN2. In the rectum and sigma, the angiogenesis presented the highest intensity in pN0 and pN1 stage lymph nodes with metastasesdecreasing in pN2 stage.

In the descendent colon segment, the MVD did not present differences between the cases with and without lymph node metastases. Our study reveals that the most indicated cases for antiangiogenic treatment seem to be the pN0 and pN1 cases in the rectum and sigma, respectively pN0 and pN2 cases in the ce pastile elimina viermii colon.

We tend to believe that abdominal cancer mri angiogenesis intensity in CRC is higher in early-stages of the tumoral proliferation but it is not an increasing process, having rather an oscillating character. Therefore, the angiogenesis remains an independent prognostic and predictive factor and the antiangiogenic treatment is necessary to be individualized for each patient. Myocardial stunning. Morphological studies in acute experimental ischemia and intraoperatory myocardial biopsies D.

Laky, Liliana Abdominal cancer mri, V. Cândea Myocardial stunning represent a consequence of abdominal cancer mri ischemia with reversible regional contractile dysfunction dependent persist from minute to days after reperfusion, despite the absence of irreversible damage and restoration of coronary blood flow.

The evolution of these new ischemic entity were described by experimental acute ischemia and repeated intraoperatory myocardial biopsies effectuated near patients with heart disease, excluding those with cardiac failure and atrial fibrillation. Using histological histoenzymological and particularly ultrastructural methods, only reversible mitochondrial and sarcoplasmatic reticulum lesions, slight glycogen granules depletions and sporadical dissociation of myofilaments by edema were seen.

Major mechanism for the state was suggested: generation of oxygen derived free radicals with consequent oxidative stress and impaired calcium homeostasis. Rare morphological appearance on stunned myocardium was signaled in the references, our collective first made these studies in Romania.

Most of them have been interpreted as epidermal proliferations secondary to the lymphoid infiltrate.

We randomly selected 21 cases of KA from our archives and performed an immunohistochemical study for CD30 in all of them. In four cases, the inflammatory infiltrate abdominal cancer mri not be studied, since the lesions had been enucleated.

From the other 17 cases, in Only one case was graded as 1, and interestingly, this case corresponded to a keratoacanthoma in regression. We also wonder if the cases described as either lymphomas or lymphomatoid papulosis with keratoacanthomatous changes are nothing more but simple keratoacanthomas.

Petrisor, Simona Eliza Abdominal cancer mri, Maria Sajin, Gioconda Dobrescu, Irina-Draga Caruntu This paper develops a comparative study between similar subtypes of colonic and rectal adenocarcinoma, based on their immunohistochemical profiles for Ki, p53 and bcl-2 markers, in order abdominal cancer mri evaluate the prediction value for the investigated markers, according to the histologic subtype and location.

Thirty cases of adenocarcinoma were investigated, 15 with colonic and 15 with rectal location. For both locations, the cases included five well-differentiated, five moderately differentiated and five low differentiated subtypes. The semiquantitative analysis of the immunohistochemical reactions was based on the Ki and p53 index, respectively, counted as number of positive cells from abdominal cancer mri and negative cells.

The mean value of Ki index for colonic, respectively rectal adenocarcinoma was The abdominal cancer mri reaction for bcl-2 was present in seven The use of the Wald tests permitted the assessment of the predictive power for the investigated markers according to the pathologic subtype and location.

The immunohistochemical evaluation of Ki, p53 and bcl-2 yields refined information on colorectal tumor biology. Our study confirms, from the statistic point of view, the role of p53, followed by Ki, as predictive factors. Prostate-specific antigen may serve as a pathological predictor in breast cancer Diana Narița, A.

Anghel, Marilena Motoc PSA prostate-specific antigena serine protease with chymotrypsin-like activity is the most useful tumor marker for prostate cancer screening, diagnosis, prognosis and monitoring.

The identification of PSA in normal and tumoral mammary gland was regarded as a curiosity, but the confirmation of PSA expression in the mammary gland by others teams of researchers and the identification of specific mRNA in tumors with PSA immunoexpression initiated new perspectives for studies.

The aim of this study was to examine the prevalence of PSA in breast cancers and to evaluate the correlations between PSA expression and some clinicopathological markers. PSA expression was observed in Angiogenesis and tumor histologic type in primary breast cancer patients: an analysis of needle core biopsies S. Vameşu Angiogenesis, the formation abdominal cancer mri new blood vessels from a preexisting vascular bed, is a complex multistep process, which abdominal cancer mri also permit metastasis.

To investigate how tumor angiogenesis correlates with tumor histologic type in breast carcinoma diagnosed on core biopsy, microvessels were counted and graded the density of microvessels within the initial invasive carcinomas of abdominal cancer mri. Using laryngeal squamous papilloma pathology microscopy, the number of microvessels was counted manually in a subjectively selected hot spot in the most active areas of neovascularization per x fieldand their values were separated as above or below median low and highwithout knowledge of the outcome in the patient or any other pertinent variable.

When tumors were classified as high or low MVD, based on a cut-off value Assessment of tumor angiogenesis may therefore prove valuable in selecting patients with early breast carcinoma for aggressive therapy. Mărgăritescu, M. Surpățeanu, L. Stepan In spite of the progresses achieved in abdominal cancer mri treatment, paraziți în tratamentul copiilor and chemotherapy, the survival rate in oral squamous cell carcinoma OSCC remain unchanged among past three decades, which made this neoplasia a major problem of health in the entire world.

Considering the differentiation grade, the cases were histopathologically classified as 9 cases of well-differentiated squamous carcinoma, 14 cases of moderately differentiated squamous carcinoma, and 19 cases of poorly differentiated squamous carcinoma.

The E-cadherine immunoexpression study indicated an immunostaining degree 3 in well-differentiated squamous carcinoma, 2 in moderately differentiated squamous carcinoma, and 1 in poorly differentiated squamous carcinoma. The results of CD44 immunostaining indicated in most of the cases an immunostaining degree 2, especially in moderately differentiated OSCC. Immunostaining degree 1 corresponded to poorly differentiated OSCC. The results indicate the possibility of using the two-immunohistochemical markers as prognostic factors in OSCC.
