1. Efeitos de um extrato aquoso de porangaba (Cordia salicifolia) na marcação de constituintes sanguíneos com tecnécio-99m e na morfologia de hemácias
Effects of a Cordia salicifolia (porangaba) extract on the labeling of blood cells (BCs) with technetium-99m ((99m)Tc) and on the morphology of red BCs were evaluated. Labeling of cellular and molecular structures with (99m)Tc depends on a reducing agent. Some physical characteristics, as visible absorbance spectrum, electric conductivity, and refractive ind

3. Estudo de efeitos de um extrato aquoso de farinha de casca de maracujá (Passiflora edulis f. flavicarpa) na marcação de constituintes sangüíneos com Tecnécio 99m, na morfometria das hemácias e na biodisponibilidade do radiofármaco Pertecnetato de Sódio em ratos Wistar
Blood constituents labelled with technetium-99m (99mTc) has been used with radiobiocomplexes in several procedures in nuclear medicine. Some natural and sintetic drugs are capable to interfere on the labeling of blood constituents with 99mTc, on the morphology of red blood cells (RBC) and on the biodistribution of radiobiocomplexes. The aim of this study was

4. Effect of an extract of Artemisia vulgaris L. (Mugwort) on the in vitro labeling of red blood cells and plasma proteins with technetium-99m
O objetivo desse trabalho foi avaliar o efeito da Artemisia vulgaris L.(artemisa) na marcação dos constituintes sangüíneos com tecnécio-99m (99mTc). Amostras de sangue obtidas de ratos Wistar foram incubadas com um extrato de artemisa e o processo de radiomarcação dos constituintes sangüíneos foi realizado. Plasma e células sangüíneas foram isola

5. Efeitos de um extrato aquoso de buzhong yi qi wan (fórmula magistral chinesa) na marcação de constituintes sanguíneos com tecnécio-99m, na morfologia e na fragilidade osmótica de hemácias de ratos Wistar
Technetium-99m (99mTc) has been used to obtain several radiobiocomplexes utilized to aid in the diagnosis of diseases. Blood constituents, as red blood cells (RBC) and plasma proteins, have been labeled with 99mTc. Natural and synthetic drugs can alter the labeling of these constituents. The aim of this work was to investigate the possibility of a Bu

6. Comparação de efeitos dos extratos de Hypericum perforatum (Hipérico) e de Mentha crispa (Hortelã) em diferentes modelos experiemtais
Avaliações clínicas têm sido possíveis com radiobiocomplexos marcados com tecnécio-99mTc (99mTc). Drogas naturais ou sintéticas são capazes de interferir na marcação de estruturas sanguíneas com 99mTc, assim como na biodistribuição de radiobiocomplexos. Também tem sido descrita a toxicidade de vários produtos naturais. O objetivo deste estudo

7. An aqueous extract of Pfaffia sp. does not alter the labeling of blood constituents with technetium-99m and the morphology of the red blood cells
Plants have been used for the human beings as food, as additives and/or as medicines. There are controversies about the biological effects of several natural products and, it is worthwhile to try to develop experimental assays to evaluate properties of extracts of plants. Pfaffia sp. is utilized in popular medicine and various properties have been attributed

8. Avaliação dos efeitos do extrato etanolico de Curatella americana sobre a marcação de elementos sanguineos com tecnecio 99M e na sobrevivencia de cultura bacteriana
Technetium 99m (Tc-99m), as sodium pertechnetate (Na99m,-c04), is a radionuclide employed in nuclear medicine clinical evaluations. Curatella americana is a plant from the Brazilian "cerrado" and its bark is used as antiulcerogenic. It has been described that the interaction of drugs alters the biodistribution of radionuclides, as well as its binding to bloo

9. Effect of Ginkgo biloba on the labeling of blood elements with technetium-99m: in vitro study
Ginkgo biloba is the phytoterapic most used in popular medicine in the treatment of cerebral senescence. Red blood cells (RBC) labeled with technetium-99m (Tc-99m) is used for several evaluations in nuclear medicine. This labeling depends on a reducing agent, usually the stannous ion. Any drug, which alters the labeling of the tracer, could be expected to mo

10. Effect of barbatimão [Stryphnodendron adstringens (Mart.) Coville] infusion on the labling of blood elements with technetium-99m
The Barbatimão is a tree which bark is rich in tannin. It is used on popular medicine as a wound healing agent, in the treatment of gastric lesions, as anti-leishmanial agent and as anti-inflammatory. Red blood cells (RBC) are labeled with technetium-99m (Tc-99m) and are utilized in many procedures in nuclear medicine. Some authors have reported that drugs

11. Radiometal labeling of recombinant proteins by a genetically engineered minimal chelation site: technetium-99m coordination by single-chain Fv antibody fusion proteins through a C-terminal cysteinyl peptide.
We describe a method to facilitate radioimaging with technetium-99m (99mTc) by genetic incorporation of a 99mTc chelation site in recombinant single-chain Fv (sFv) antibody proteins. This method relies on fusion of the sFv C terminus with a Gly4Cys peptide that specifically coordinates 99mTc. By using analogues of the 26-10 anti-digoxin sFv as our primary mo
