Na deficiência de ferro, que pode culminar anemia por disfunção eritropoiética, prevalente em leitões e seres humanos, a hemoglobina pode ter alterações estruturais denominadas hemoglobinopatias. O estudo determinou a influência do ferro nos tipos de hemoglobina de leitões neonatos. Perante os resultados se verificou que hemoglobina do leitão tem corrida semelhante à humana, e nos animais que apresentaram anemia ferropriva não houve aparecimento do traçado Hb A2, que pode estar diminuída em casos de deficiência de ferro em seres humanos. / Hemoglobin is a globular protein consisting of the protein fraction (globin chains), heme fraction which is the binding of the bivalent iron ion, and the combined globin help classify the hemoglobin in Hb Adult (Hb A), Fetal (Hb F) and Adult 2 (Hb A2). The iron deficiency can predispose anemia by erythropoietic dysfunction, prevalent in pigs and humans and the hemoglobin may have structural changes denominated hemoglobinopathies. The study determined the influence of iron to the types of hemoglobin neonate pigs. On the results was found that the pig hemoglobin is similar to human in electrophoresis. The piglets showed deficiency anemia there was appearance of line Hb A2, which may be diminished in cases of iron deficiency in humans. / CNPq: 158890/2015-9 / CNPq: 130399/2014-0 / CAPES: 23028003201-2014-41

Medeiros, Fernanda Peres. January 2009 (has links)
Orientador: Julio Carlos Canola / Banca: Áureo Evangelista Santana / Banca: Georgea Bignardi Jarretta / Resumo: No presente estudo foi analisado o parênquima hepático com características homogêneas e ecogenicidade difusa reduzida (G1), aumentada (G2) e normal (G3), em relação ao perfil dos animais, dimensão do fígado e achado bioquímico e hematológico. Amostras de sangue obtidas por punção venosa da jugular ou da cefálica do antebraço foram encaminhadas para realização de hemograma e dosagem sérica de ALT, FA, proteínas totais, albumina, globulina, uréia e creatinina. Dos 30 cães que compuseram o G1, 30 (100%) apresentaram evidência das paredes portais e da vesícula biliar, 23 (76,67%) fígado com dimensão preservada e bordos em ângulos agudos, 15 (50%) faixa etária entre 1 e 6 anos de idade e 8 (26,67%) eram da raça lhasa apso. Não houve predisposição quanto ao sexo, assim como não foram identificadas alterações significativas nos exames bioquímicos e hematológicos dos cães do G1. Quanto aos diagnósticos clínicos atribuídos para estes cães, houve maior prevalência de gastrinterite (43,33%). Dos 30 cães do G2, 27 animais (90%) apresentaram hepatomegalia e arredondamento dos bordos hepáticos, 18 (60%) tinham idade superior a 9 anos, 16 (53,33%) eram fêmeas e 9 (30%) eram da raça poodle. Houve elevação da atividade sérica de FA e elevação de ALT, redução nos níveis de proteínas séricas totais, albumina, globulinas, eritrócitos e volume globular, além de leucocitose por neutrofilia, com desvio à esquerda, eosinopenia, linfopenia e monocitose nos cães do G2. Neste grupo houve prevalência de doenças metabólicas (54%), como diabetes mellitus e hiperadrenocorticismo, além das hepatopatias crônicas (17%), atribuídas ao uso contínuo e prolongado de corticóide e drogas anticonvulsivantes. Dos 30 cães do grupo controle (G3), 22 (73,33%) apresentaram...

Blood samples obtained by cephalic or jugular venipunture were submitted for hemogram and ALT, ALP, total proteins, albumin, globulin, urea and creatinine analysis. Among the 30 dogs in G1, 30 (100%) presented portal venous and gall bladder wall clarity, 23 (76.67%) presented normal liver size and edges, 15 (50%) were from 1 to 6 years old and 8 (26.67%) belonged to the lhasa apso breed. No predispositions were found according to gender, as well as no significant alterations in biochemical and hematological exams were observed in G1. The most prevalent disease found in this group was gastroenteritis (43.33%). Among the 30 dogs in G2, 27 (90%) presented hepatomegaly and rounded hepatic edges, 18 (60%) were over 9 years old, 16 (53.33%) were female and 9 (30%) belonged to the poodle breed. The laboratorial findings related to this group were increased ALT and ALP serum activity, decreased levels of total protein, albumin, globulin, erythrocytes and hematocrit, as well as leukocytosis with neutrophilia and a left shift, eosinopenia, lymphopenia and monocytosis. The most prevalent diseases found in this group were metabolic disorders (54%), such as diabetes mellitus and hyperadrenocorticism, and chronic hepatopathies (17%) due to prolonged and continuous use of corticoid and anticonvulsive drugs. Among the 30 dogs in the control group (G3), normal liver size and edges were presented in 22 (73.33%). In this group, no alterations were seen in laboratorial exams. / Mestre

Os itens verificados pelo controle de qualidade devem apresentar um percentual de conformidade superior a 75%, e os estéreis deverão apresentar conformidade superior a 99,5%. O objetivo do presente trabalho foi controlar a qualidade da triagem hematológica e dos hemocomponentes: concentrado de hemácias (CH), plasma fresco congelado (PFC), crioprecipitado (CRIO) e concentrado de plaquetas (CP) produzidos no Hemocentro do Hospital das Clínicas da Faculdade de Medicina da Universidade Estadual Paulista da cidade de Botucatu. Este estudo foi dividido em duas etapas, na primeira foram realizados os controles da qualidade da triagem hematológica e analisadas 747 amostras de sangue obtidas de doadores voluntários de sangue. A metodologia utilizada nesta etapa envolveu a realização de hematócrito de ponta de dedo pelo método clássico de centrifugação utilizando equipamento Hemato Stat II e a determinação de hematócrito usando a técnica de referência automatizada (equipamento Horiba ABX). No período da segunda etapa, foram controladas 643 amostras, distribuídas em CH (282), PFC (150) Crio (20) CP standard (181) e CP aférese (10).Para o controle de qualidade dos CHs foram analisados os aspectos, volume e hematimetria. Para os produtos plasmáticos foram os aspectos, volume e fatores da coagulação (TP, TTPA, FV, FVIII e fibrinogênio). E para o controle dos CPs foram os aspectos, volume, pH, contagem do numero de plaquetas e cultura microbiológica. No controle de qualidade da triagem hematológica o resultado obtido para comparação entre as duas técnicas apresentou uma discrepância de 48,1% entre elas.

The blood and their components should be collected, processed and transfused under the most rigorous conditions. The items checked by quality control must present a compliance rate of over 75%, and the sterile line must be more than 99.5%. The objective of the present work was to control the quality of the hematological screening and of the blood components: red blood cells concentrated (RBCC), fresh frozen plasma (FFP), cryoprecipitate (Cryo) and platelets concentrates (PC) produced in the Hemocenter of the Hospital of Clinics of the Faculty of Medicine, Universidade Estadual Paulista, in Botucatu. This study was divided in two stages. In the first stage, the quality controls of hematological screening were applied, and blood samples from 747 voluntary donors were analysed. The methodology used in this stage involved the realization of finger tip hematocrit by the classic method of centrifugation, using Hemato Stat II equipment, and of hematocrit determination, using the technique of automated reference (equipment Horiba ABX). During the second stage, 643 samples were controlled and distributed in: RBCC (282), FFP (150), Cryo (20), PC (181) and apheresis PC (10). For quality control of RBCC, the aspects, volume and hemocytometry were analyzed. For the plasmatic products, the aspects, volume and factors of coagulation (PT, APTT, FV, FVIII and fibrinogen) were analysed.And for the control of PCs they were, the aspects, volume, pH, counting of the number of platelets and microbiological culture.

Avaliação hematológica, bioquímica e hemostática de bezerros Brahman provenientes de produção in vitro (PIV) e bezerros Brahman de produção in vivo /

Mendonça, Adriane Jorge. January 2007 (has links)
Orientador: Regina kiomi Takahira / Banca: Raimundo Souza Lopes / Banca: Alexandre Secorun Borges / Banca: Graziela Barioni / Banca: Mara Regina Stipp Balarin / Resumo: Avaliou-se alterações na hematologia, bioquímica e hemostasia de 112 bezerros Brahman produzidos in vitro (PIV) comparados a 20 bezerros Brahman produzidos in vivo, bem como avaliou-se a influência dos fatores etários e sexuais sobre os mesmos exames laboratoriais nos bezerros PIV em segundo estudo. Para tanto, os 112 bezerros PIV foram divididos em 4 grupos: 0-15 dias, 16-40 dias, 60-80 dias e 81-100 dias de idade com subdivisões para sexo em cada grupo. Todos foram submetidos aos exames de hemograma, às avaliações bioquímicas da uréia, creatinina, das proteínas totais séricas (PTS), albumina e globulina e da atividade sérica das enzimas aspartato amino transferase (AST) e creatina cinase (CK). A hemostasia foi avaliada pela determinação do tempo de protrombina (TP), tempo de tromboplastina parcial ativada (TTPA) e concentração do fibrinogênio. Analisando os resultados, concluiu-se que houve influência da produção in vitro nos valores bioquímicos do soro de bezerros Brahman manifestados por aumento das globulinas e diminuição da albumina em animais PIV; o fator etário influenciou na variação dos parâmetros analisados, refletidos por diminuição de neutrófilos segmentados, monócitos, uréia, CK, PTS, globulinas e fibrinogênio, e por aumento dos linfócitos e da creatinina com o avanço da idade. Machos tem valores médios de linfócitos (grupos de 0-15 e 60-80 dias de idade) e leucócitos totais (grupo de 60-80 dias) superiores às fêmeas. Fêmeas tem valores médios de monócitos (grupos de 16-40 e 60-80 dias) e de CK (grupo de 16-40 dias de idade) superiores aos machos / Abstract: Changes on hematology, biochemistry and hemostasis were evaluated in 112 Brahman's calves derived from in vitro-produced embryos (IVP) compared with 20 Brahman's calves derived from in vivo production. Age and sexual influences were evaluated on 112 IVP Brahman's calves divided in four groups: 0-15, 16-40, 60-80 and 81-100 days of age; each group were further subdivided according to their gender. All calves were submitted to the following laboratory tests: hemogram, urea, creatinine, total serum proteins (TSP), albumin and globulin levels and the serum activities of aspartate aminotransferase (AST) and creatine kinase (CK). The hemostasis was evaluated by the prothrombim time (PT), activated partial thromboplastin time (aPTT) and fibrinogen concentration. According to the results, it was concluded that albumin and globulin were influenced by the IVP, characterized by an increase in globulin and a decrease in albumin in IVP animals. Age have influenced the variation on the parameters analyzed, characterized by a decrease in the segmented neutrophils, monocytes, urea, CK, TSP, albumin and fibrinogen concentrations, and a creatinine increase with the age advance. Males has higher lymphocytes (groups of 0-15 and 60-80 days of age) and leukocytes (group of 60-80 days of age) values than females. Females has higher monocytes (groups 16-40 and 60-80 days of age) and CK (group of 16-40 days of age) values than males / Doutor

'n Ondersoek na die vir bepaling van serum- en toepassing van essaieringstelle verwysingswaardes vir vitamien rooiselfolaat by verskillende etniese groepe

Cloete, Henny January 1992 (has links)
Thesis (MTech (Medical Technology))--Cape Technikon, 1992. / As early as 1822 it was discovered that treating a patient, who had a macrocytic anaemia, with a diet containing liver, a rich source of folic acid (folacin), brought about an excellent haematological response. extract, a source of The same happened in 1851 when a yeast vitamin B12 (cobalamine), corrected a megaloblastic anaemia. It is well known that a lack of either one or both of these vitamins is responsible for a megaloblastic anemia which has been shown to be hematologically indistinguishable yet requires different treatment to correct. It is therefore important to make a correct diagnosis as to the cause of the illness in a megaloblastic anaemia by the measurement of vitamin B12 and folate levels. Various laboratory test methods were developed over the past 20 to 30 years and through constant improvement culminated in the current radio immune assay (RIA) technique used for the measurement of vitamin B12 and folate values. This method has many advantages over the microbiological method that preceeded it, but is still dependent on normal values or reference ranges. These reference ranges, supplied with each test kit, are obtained from a white American population and are probably only applicable to the white South African population.

EvoluÃÃo das polÃticas de hemoterapia no Brasil: o sistema pÃblico de hemoterapia do Cearà / Development of policies in hemotherapy in Brazil: the public system of Cearà hemotherapy

Francisco Placido de Sousa Basilio 03 April 2002 (has links)
A hemotransfusÃo à uma necessidade que acompanha a humanidade desde seus primÃrdios. A partir do sÃculo XV vÃrios estudiosos tentaram utilizar o sangue atravÃs da transfusÃo. Somente no sÃculo XX com a descoberta dos grupos sangÃÃneos e a descriÃÃo da prova cruzada, tornaram a transfusÃo como um mÃtodo cientÃfico. Os institutos de transfusÃo de sangue foram criados na Europa a partir do ano de 1920. No Brasil somente na dÃcada de 1940 surgiram as primeiras organizaÃÃes hemoterÃpicas. Em 1949 surgiu a Sociedade Brasileira de Hematologia e Hemoterapia. A primeira Lei incentivando a doaÃÃo voluntÃria de sangue no Brasil data de 1950. Com o surgimento do movimento militar em 1964 e a constataÃÃo de que numa eventual catÃstrofe nÃo haveria sangue suficiente para atender a demanda nacional, à recomendada uma definiÃÃo na PolÃtica Nacional de Sangue. Em 1965 à editado pelo Governo Federal a Lei n 4.071 disciplinando a atividade hemoterÃpica no paÃs. E este foi o primeiro passo para regulamentar estes serviÃos. Somente em 1980 à criado o Programa Nacional de Sangue e Hemoderivados â Pro-Sangue tendo com meta a implantaÃÃo dos Hemocentros no Brasil. Comparando-se o ano de 1999 quando 2.096.190 coletas de sangue foram realizadas pela Hemorrede Nacional em relaÃÃo ao ano de 2000 quando 2.329.937 pessoas doaram sangue, notamos um aumento significativo no nÃmero de doadores em todo o Brasil. A GerÃncia Nacional de Sangue e Hemoderivados responsÃvel pelo setor de sangue no Brasil estima o percentual das doaÃÃes espontÃneas em torno de 41,74% sendo que 54,99% representam os doadores de reposiÃÃo. Em 1971 surgem os primeiros bancos de sangue privados no CearÃ. Em 1983 HEMOCE inicia suas atividades. ApÃs dez anos os Hemocentros Regionais sÃo implantados no interior do Estado. Hoje a cobertura hemoterÃpica no Cearà se aproxima dos 100% atendendo a todos os hospitais pÃblicos e privados. / The hemotransfusion is a need which has accompanied the humanity since its origins. Starting from the 15th century, several specialists tried to use the blood trough transfusion, however, only in the 20th century, with the discovery of blood groups and description of the crossed proof, transfusion was recognized as a scientific method. Blood Tranfusion Institutes were created in 1920, but in Brazil, only in the decade of 1940 apperead the first hemotherapics organizations. In this period, the Brazilian Society of Hematology and Hemotherapy was founded (in 1949) and the first law motivating the voluntary donation of blood in Brazil was written (which dates from 1950). In 1964, with the appereance of the military movement and the verification that in an eventual catastrophe there would not be enough blood to assist the national demand, was recommended a definition in the National Politics of Blood. In 1965 was edited by the Federal Government the law number 4.071 which has established rules to hemotherapic activity in the country and this was the first step to regulate this kind of service. But only in 1980 the National Program of Blood and Stems â Pro-Sangue was created tends with main goal the implantation of Hemocenters in Brazil. Comparing the year 1999, when 2.096.190 blood collections were accomplished by National Hematology Network, with the year 2000, when 2.329.937 people donated blood, we noticed a significant increase in the number of donors throughout Brazil. The National Management of Blood and Stems, responsible for the blood section in Brazil, steems the percentage of spontaneous donations around 41,74% and in this estimate 54,99% represent replacement donors. In 1971, the first private blood banks showed up in CearÃ, and in 1983, HEMOCE, started to operate. Ten years later, Regional Hemocenters was implanted in the country side of the state. Nowadays, the hemotherapic coverage in Cearà approaches 100%, assisting all of the public and private hospitals.
