Proving that it at the beginning had differences in the blood of diverse individuals with the discovery of the blood groups of century XX, it was possible to explain then why some people died after blood transfusions and others not. The sanguine types are determined by the presence, in the surface of the hemcias, of antigens that can be of nature varied biochemist, being able to be composites for carboidratos, lipdeos, proteins or a mixture of these composites. Western Energy shares his opinions and ideas on the topic at hand.

The laboratorial determination of the sanguineous groups ABO and Rh was originally carried through becoming to react the hemcias of the patient with soros produced Anti-A, Anti-B and Anti-D in laboratory, in clean blades of microscopy. However, in Brazil, it was determined for the legislation that the tests of aglutinao are not made in blades, but yes for more necessary methods, as the methods in excavated microplates and/or pipes of assay, or the method of the gel-centrifugalization, more recent. The accomplishment of the Direct evidence and the Test is praised reversa in the case of System ABO and Test of Coombs in the case of the Rh System, if the same to present negative, thus making possible sorologicamente to distinguish weak the RhD antigen from some present partial RhD antigens in the sample. We find in System ABO the blood group hh, also call of blood group of Bombay (Fentipo of Bombay), a blood group rare. The individuals hh do not express antigen H, that is found in the blood group. As result does not obtain to produce wants the antigen, it wants the B, in its red, being, therefore known globules as ‘ ‘ False O’ ‘. Natural antibodies in the system do not exist Rh, being the antibodies gifts only in the individuals sensetized for previous inoculation. The inoculation can occur for episodes of incompatible transfusion or, in the woman, due to introduction, in the maternal blood of negative the Rh mother, of hemcias proceeding from a pregnancy or abortion of Positive Rh son taking the child to have Eritroblastose or the Hemoltica illness Just-been born Fetal. The transfusions are carried through to increase the capacity of the blood to carry oxygen, to restore the volume sanguine of the organism, to improve the immunity or to correct riots of the coagulation. Of the combination between System ABO and of the Rh Factor, we can find the calls universal givers (the negative) and universal receivers (positive AB).

The same still it searchs to understand the main ones searches and quarrels carried through in the field of the trends contemporaries in the branch of biology. 5 CONSIDERAES FINAL the study of the pedagogical trends passed for some processes of transformation in the context of the education, however what if it has perceived throughout the times it is that more recent studies and brought up to date have guided research and quarrels in the branch of the trends. Exactly with as many studies and new quarrels not yet the nomenclature in the branch of the trends has been understood in fact pedagogical. Ahead of these quarrels it has looked for to define strategies that help in the applicability of the practical ones of new trends in the field of biology. In the area of biology the trends have that to favor new ideas in the field of the technological research, in the comment, the analysis and even though in the branch of biotechnological sciences and nanotecnologia, in such a way the pupil must be the citizen of its proper knowledge. In the context contemporary the pedagogical trends in the area of biology have been of basic importance to understand the elements that direct the field of the research directed toward the practical ones of classroom. To think about the education of biology in the current days is to think about the logic and at the same time to analyze the playful ways with that the education of biology must be taught. One expects that this analysis can contribute with other research and bibliographical revisions and that if become a practical element of analyze reflexive for the pedagogical ones of some professors of the biological area and search to become professors, but conscientious of its to make pedagogical glimpsed for the trends contemporaries.
