ABSTRACT
The mouse was chosen as an animal model because of the possibility of being genetically manipulated, having lineages originated through induced or spontaneous mutations. The mutant pearl mice have reduced levels of adenine and serotonin nucleotides in the dense platelet granules and they are a model for Hermansky- Pudlak syndrome. The Vwf-/- mice were genetically modified to present mutations in the Vwf gene, to study von Willebrand disease. Other mice are genetically modified to have hemostatic changes, such as type A hemophilia (deficiency of coagulation factor VIII) and B (deficiency of coagulation factor IX). This work aimed to analyze the blood count of pearl mice, hemophiliac A and B and von Willebrand disease and test collection techniques. Twenty mice from each strain were used, ten males and ten females that were weighed weekly until the age of two months, after which they were weighed monthly. Three blood samples were collected from each animal in three different ways caudal vein, saphenous vein and retro-orbital plexus. Regarding the growth curve, males are heavier than females, less HB males who are smaller than children up to the fifth week of age. And there was little difference in weight between the lines compared to the genetic background. The analyzed data of the hemograms were the white blood count (WBC), red blood cell count (RBC), hematocrit (HCT) and platelet count (PLT). It was concluded that the best collection method was the retro- orbital for all strains and the saphenous vein in the case of pearls, the least recommended method was the caudal vein. The weight curve is important to obtain a weight x age relationship over the physical development of the animals. It was noticed that hemophiliacs A really have high mortality, probably caused by internal bleeding. With hemogram data, there were also some differences between strains, such as the WBC of pearls and HA being higher than that of C57BL/6 and Vwf-/- and C57BL/6 also have a higher RBC value than the other strains and the HB, the lowest. The HCT had very similar values, varying between 41% and 51%. And PLT tend to have a higher value among males than females of all strains. It was possible to see some differences between lineages, gender and age, but more collections are still needed.
RESUMO
O camundongo foi escolhido como modelo animal pela possibilidade de ser manipulado geneticamente, tendo linhagens originadas através de mutações induzidas ou espontâneas. Os camundongos pérolas mutantes possuem níveis reduzidos de nucleotídeos de adenina e serotonina nos grânulos densos de plaquetas e são um modelo para a síndrome de Hermansky-Pudlak. Os camundongos Vwf-/- foram modificados geneticamente para apresentarem mutações no gene Vwf, para estudo da doença de von Willebrand. Outros camundongos são modificados geneticamente para apresentarem alterações hemostáticas, como as hemofilias do tipo A (deficiência do fator VIII da coagulação) e B (deficiência do fator IX da coagulação). Este trabalho teve como objetivo analisar o hemograma de camundongos pérolas, hemofílicos A (HA) e B (HB) e Vwf-/- testar técnicas de coleta. Foram usados 20 camundongos de cada linhagem, sendo dez machos e dez fêmeas que foram pesados semanalmente até os dois meses de idade, após isso foram pesados mensalmente. Foram coletadas três amostras de sangue de cada animal de três vias distintas veia caudal, veia safena e plexo retro-orbital. Com relação à curva de crescimento, os machos são mais pesados do que as fêmeas, menos os machos HB que eram menores que as fêmeas até a quinta semana de idade. E houve pouca diferença de peso das linhagens comparadas com o fundo genético. Os dados analisados dos hemogramas foram a contagem leucocitária (WBC), contagem de hemácias (RBC), hematócrito (HCT) e contagem de plaquetas (PLT). Conclui-se que o melhor método de coleta foi a retro-orbital para todas as linhagens e a veia safena no caso dos pérolas, e o método menos recomendado foi pela veia caudal. Percebeu-se que os hemofílicos A realmente possuem alta mortalidade, provavelmente causada por hemorragias internas. Com os dados dos hemogramas, houve também algumas diferenças entre as linhagens, como o WBC dos pérolas e HA ser mais alto do que dos C57BL/6 e Vwf-/- e os C57BL/6 também possuem um valor de RBC mais alto do que as outras linhagens e os HB, o mais baixo. O HCT teve valores bem parecidos, variando entre 41% e 51%. E as PLT tendem a ter um valor maior entre os machos do que das fêmeas de todas as linhagens. Foi possível ver algumas diferenças entre as linhagens, gênero e idade, porém ainda é necessário mais coletas.
