Chrysobalanus icaco (abajeru; C.icaco) is recommended in the treatment of diabetes and other clinical disorders. Blood constituents labeled with technetium-99m (99mTc) are used in nuclear medicine. The aim of this study was to verify the effects of an abajeru extract on the labeling of blood constituents with 99mTc and on the shape of red blood cells (RBC). Blood samples(Wistar rats) were incubated with abajeru extract and the labeling of blood constituents with 99mTc and morphology of RBC were carried out. The results showed significant (P&lt;0.05) alteration of labeling of blood constituents with 99mTc and the morphometry (perimeter/area ratio) of the RBC in presence of the extract. These data suggest that this abajeru extract could alter the labeling of...

Head and neck cancer is one of the 10 most frequent cancers worldwide, with an estimated 500000 new cases diagnosed annually. Treatment of head and neck cancers require a multidisciplinary approach due their complexity and the functional and esthetic alterations that cancer can cause. The interest of the scientific community in a specific subject can be evaluated by analyzing of the number and the quality of published papers on the topic. The information obtained from PubMed (www.ncbi.nlm.nih.gov/sites/entrez) has been used as a tool in various publications to aid the evaluation of the scientific interest in specific research areas The aim of this work is to evaluate, using PubMed, the scientific interest in studies of head and neck cancer treatments such...

The aim of this study was to evaluate the effect of in vivo treatment with an aqueous cinnamon extract on the labeling of blood constituents with 99mTc and on the morphology of red blood cells from Wistar rats. Animals were treated with cinnamon extract at different doses and for different periods of time. As controls, animals treated with 0.9% NaCl. Labeling of blood constituents with 99mTc was performed. Plasma, blood cells and insoluble fractions were isolated. Radioactivity in each fraction was counted and the percentage of radioactivity (%ATI) was calculated. Also, blood smears were prepared to morphological analysis of red blood cells from. Data showed that in vivo cinnamon extract did not significantly (p&gt;0.05) modify the %ATI of blood...

Buzhong Yi Qi Wan (Buzhong) is a medicinal herb widely used in Traditional Chinese Medicine to treat the digestive and circulatory systems. Red blood cell and plasma proteins labeled with technetium-99m (99mTc) are used in nuclear medicine. The aim of this work was to investigate the effects of an aqueous Buzhong extract on the labeling of blood constituents with 99mTc. Heparinized blood (Wistar rats) was incubated in vitro with different Buzhong extract concentrations and 99mTc-labeling was performed. Plasma (P) and blood cells (BC) were separated and soluble (SF-P, SF-BC) and insoluble (IF-P, IF-BC) fractions were isolated. The radioactivity on blood constituents was determined and the percentage of incorporated radioactivity (%ATI) was calculated....

Clove (Caryophyllus aromaticus L.) has been used for clinical procedures. Blood constituents labeled with technetium-99m (99mTc) are used in nuclear medicine. The aim of this work was to evaluate the effects of clove extract on the labeling blood constituents with 99mTc and on the morphology of red blood cells. Blood samples were incubated with clove, stannous chloride and 99mTc. Plasma, blood cells, insoluble fractions of plasma and blood cells were separated. The radioactivity was counted and percentage of radioactivity (%ATI) to each blood fraction was calculated. The shape and morphometric parameter (perimeter/area ratio) were evaluated. Clove extract altered significantly (p&lt;0.05) the %ATI of blood constituents and the shape of red blood cells...

Autores: Santos-Filho,Sebastião David; Presta,Giuseppe Antonio; Paoli,Severo de; Missailids,Sotiris; Fonseca,Adenilson de Souza da; Bernardo-Filho,Mario.
Radiotherapy is a cancer treatment that uses high-energy X-rays or other types of ionizing radiation to try to kill the cancer cells in various organs/tissues. PubMed is a database used as a tool in various publications. The aim of this work was to evaluate, in the PubMed, the number of publications (NP) in radiotherapy and cancer in various organs related to the pelvic floor as well as brachytherapy. The searches were performed (August 2008) in the PubMed (http://www.pubmed.com) using the words: (i) radiotherapy (RT) or cancer (CA), (ii) RT and CA, (iii) RT and CA and prostate, RT and CA and testis, RT and CA and breast, RT and CA and kidneys, RT and CA and vulva, RT and CA and vagina, RT and CA and penis, RT and CA and uterus, RT and CA and ovary, RT and...
