Proposta de um protocolo de terapia celular para o tratamento da doença pulmonar obstrutiva crônica

The main feature of pulmonary emphysema is airflow obstruction resulting from the destruction of the alveolar walls distal to the terminal bronchioles. Existing clinical approaches have improved and extended the quality of life of emphysema patients. However, no treatment currently exists that can change the disease course and cure the patient. The different therapeutic approaches that are available aim to increase survival and/or enhance the quality of life of emphysema patients. In this context, cell therapy is a promising therapeutic approach with great potential for degenerative pulmonary diseases. In this protocol proposition, all patients will be submitted to laboratory tests, such as evaluation of heart and lung function and routine examinations. Stem cells will be harvested by means of 10 punctures on each anterior iliac crest, collecting a total volume of 200 mL bone marrow. After preparation, separation, counting and labeling (optional) of the mononuclear cells, the patients will receive an intravenous infusion from the pool of Bone Marrow Mononuclear Cells (BMMC). This article proposes a rational and safe clinical cellular therapy protocol which has the potential for developing new projects and can serve as a methodological reference for formulating clinical application protocols related to the use of cellular therapy in COPD. This study protocol was submitted and approved by the Brazilian National Committee of Ethics in Research (CONEP - Brazil) registration number 14764. It is also registered in ClinicalTrials.gov (NCT01110252). (c) 2013 Sociedade Portuguesa de Pneumologia. Published by Elsevier Espana, S.L. All rights reserved.

Expressão da proteína nuclear de proliferação celular (PCNA), da B-Catenina e do Agnor, na etapa inicial do processo de carcinogênese quimicamente induzido pelo DMBA, em borda lateral de língua de hamsters sírio dourado(Mesocricetus auratus)

The oral cancer model in hamsters shows many simílarities with developmental oral cancer in humans. The proliferating capacity is one the most characteristics of neoplásica ce/Is and detection of these ce/Is allow us, throughout of its counting, to achieve an estimated tumour growing index, with a consequent repercussion about prognostic and in the treatment of those lesions. 40 golden Syrian hamsters, both genders, aged between two to six mouth and weight 150g in average were used. The left síde of tangue of each animal was painted for eight consecutive weeks, with a solution of DMBA. Tongues were removed, fixed in 10% buffered fonnal solution. The histological slides were stained by AgNOR technique and by PCNA and β-catenin immunohistochemical antibodies. Statistical analyzes were performed by ANOVA one-way test and Tukey test. We may conclude that an association between AgNOR and PCNA might indicate the higher proliferating activity of the analyzed celIs. The experimental carcinogenesis model in hamster tongue is an available methodology for immunohistochemistry study. And finally, PCNA and β-catenin immunohistochemical antibodies may be used to analyze possible premalignant areas in oral leukoplakia

Indução de morte celular por apoptose decorrente da irradiação com Raios-X: um ensaio com células mamárias humanas tumorais

Apoptosis is a form of programmed cell death selectively removes abnormal cells, and thus contributes to maintaining the balance of the dynamics of cell reproduction. Therefore the verification of the occurrence of apoptotic cell death after a pathological stimulus is crucial for the analysis of the maintenance of normal cell cycle of a given tissue or organ. In this experiment were used cells lines human mammary tumor MDAMB231, T47, MCF7, which were irradiated with X-rays at a dose of 5 Gy in a time interval of 15 seconds, and filtration of 1mm aluminum. Samples containing the cells were grown in a specific culture medium, containing fetal bovine serum and growth factor, and two samples were prepared with each of the cell lines, one to be irradiated, and another that has not been irradiated, which denoted by negative control of the irradiation. The primary goal of the experiment was to verify and compare the rates of apoptosis in each cell lines, in which were irradiated and that were not irradiated, using flow cytometry as a method for detecting apoptotic cell death in together with specific markers annexin V and propidium iodide. Data from the readings made by flow cytometry were analyzed and interpreted using the software WinMDI statistical graph. By comparing the indices relating to the readings of positive and negative for specific markers of apoptosis, based on differences in the statistical data presented lectures regarding the cellular irradiated and not irradiated, collude cells in question once...
