1. Episodic angioedema associated with eosinophilia
Abstract: We report a 12-year-old girl who presented with recurrent angioedema on the face, trunk, and extremities, and concomitant marked weight gain for 5 years. During the episode, her white blood cell count increased to 47.7×109/L with 89.9% eosinophils, followed by elevated serum level of IL-5, IgE, IgM, and LDH. Histopathology showed perivascular eosi

2. Promoting inflammatory lymphangiogenesis by vascular endothelial growth factor-C (VEGF-C) aggravated intestinal inflammation in mice with experimental acute colitis
Angiogenesis and lymphangiogenesis are thought to play a role in the pathogenesis of inflammatory bowel diseases (IBD). However, it is not understood if inflammatory lymphangiogenesis is a pathological consequence or a productive attempt to resolve the inflammation. This study investigated the effect of lymphangiogenesis on intestinal inflammation by overexp

3. Expression of lymphatic markers and lymphatic growth factors in psoriasis before and after anti-TNF treatment
BACKGROUND: Angiogenesis is an early stage of psoriatic lesion development, but less is known about lymphagiogenesis and its role in the development of psoriasis. OBJECTIVE: To examine the expression of specific lymphatic markers and lymphatic growth factors in untreated psoriatic skin, in the unaffected skin of patients and skin of healthy volunteers, as w

4. Angiotensin II type 1 and 2 receptors and lymphatic vessels modulate lung remodeling and fibrosis in systemic sclerosis and idiopathic pulmonary fibrosis
OBJECTIVE: To validate the importance of the angiotensin II receptor isotypes and the lymphatic vessels in systemic sclerosis and idiopathic pulmonary fibrosis. METHODS: We examined angiotensin II type 1 and 2 receptors and lymphatic vessels in the pulmonary tissues obtained from open lung biopsies of 30 patients with systemic sclerosis and 28 patients wi

5. VEGF-C e densidade de vasos linfáticos em carcinoma espinocelular de boca: associação com as metástases linfonodais ocultas e com o prognóstico dos pacientes / VEGF-C and lymphatic vessel density in oral squamous cell carcinoma: association with occult lymph node metastasis and patients prognosis
This study evaluated the lymphatic vesssel density (LVD) in correlation with the vascular endothelial growth factor-C (VEGF-C) expression by tumors cells and with clinical and pathological variables in patients with oral squamous cell carcinomas (OSCC). Eighty-seven patients with primary OSCC, clinically T1N0M0 or T2N0M0, with occult lymph-node metastases (p

6. Analise comparativa da eficácia do método imuno-histoquímico (d2-40 e cd34) e coloração de rotina (he) para detecção de invação vascular linfática e sanguinea no carcinoma gástrico
BACKGROUND: Worldwide, gastric carcinoma (GC) is the second largest cause of cancer-related death. The TNM staging system for GC is widely used and it provides important prognostic information, especially with regards to the lymph node status. The presence of lymphatic invasion (LVI) detected on the primary tumor is the strongest risk factor for lymph node m

7. Comparison of blood neoangiogenesis and lymphatic vascularization in colorectal adenomas from patients with and without concomitant colorectal cancer
Blood and lymphatic vessel proliferation is essential for tumor growth and progression. Most colorectal carcinomas develop from adenomas (adenoma-carcinoma sequence) in a process due to accumulation of molecular genetic alterations. About 5% of adenomatous polyps are expected to become malignant, but data on the differential angiogenic patterns of these lesi

8. Efeito do tempo da compressão mecânica extrínseca após escleroterapia em veias de orelhas de coelhos
Introduction: The compression therapy is recognized as effective in the treatment of venous and lymphatic diseases. Despite the scientific evidence on some clinical indications, there is still much to be investigated. Objectives: To investigate whether venous compression time of 120 hours after sclerotherapy is sufficient to prevent blood reperfusion in the

9. Testicular morphology and morphometry in mice chronically exposed to arsenic / Morfologia e morfometria testicular de camundongos adultos submetidos à exposição crônica ao arsenato
There is an increasing concern about the potentially harmful effects of several environmental pollutants, as for instance, the inorganic arsenic, one of the main pollutants of the water worldwide. The intoxication by arsenic can be acute or chronic, and lead to a variety of pathologies and impairment of male reproductive system. This work aimed to investigat

10. Individual risk prediction of node and distant metastasis based on lymphangiogenic intensity in typical pulmonary carcinoid tumor / Predição do risco individual de metástase linfática e hematogênica em função da intensidade da linfangiogênese no tumor carcinóide típico broncopulmonar
Typical pulmonary carcinoids are neuroendocrine cells proliferations and they were former considered lung adenomas with no hematogenic or lymphatic metastatic potential. However, it is known that up to 20% of patients develop metastatic disease. It is mandatory that new studies be developed due to the variation in clinical presentation of these patients. It

11. Adenocarcinoma colorretal: aspectos anatomopatológicos e imuno-histoquímicos do crescimento tumoral, do citoesqueleto e de marcadores de regulação do pH intracelular / Colorectal adenocarcinoma:anatomopathological and imunohistochemical aspects of tumor growth, cytoskeleton and of intracellular pH regulator markers
The aims of this study in colorectal carcinoma were: 1) Verify the distribution of the most important anatomopathological variables, and identifying their relationship with lymph node or liver metastasis. 2) Considering the associations obtained in the first aim, a group of variables was selected to verify the prediction of lymph node or liver metastasis. 3)

12. A imunoexpressão de VEGF-A, a densidade microvascular e linfatica determinadas pelo CD34 e D2-40, podem não ser fatores inidicativos de recidiva de carcinoma invasivo inicial de mama / VEGF-A expression, microvessel and lymphatic vessel density may not be predicting factors of early breast cancer agressiveness
Objetivo: Avaliar a relação da angiogênese em carcinomas invasivos iniciais da mama com fatores clínico-patológicos indicativos de recorrência. Casuística e Métodos: Em 92 casos de pacientes com neoplasia maligna invasiva e inicial da mama e submetidas à pesquisa de comprometimento do linfonodo-sentinela (LS) pesquisou-se a imunoexpressão de VEGF-A
