| Abstract | |
We used pregnant female mongrel dogs, froco Control centers of Zoonoses of São Paulo and region, in different periods of gestation. The animais had been submïtted the general clinic examination and to a ultrasonographyc evaluation for determination of the time of pregnancy period. The development of technologies can assist the prematura diagnoses of genetic alterations, in animais is something new, however still basic for the future. One of these techniques and the biopsy of fetal chorion which in allows them to collect in little invasive fetal tissue and to submit this the chromosomic and DNA examïnations. Through this we obtain to identify the embryo sex with total exactness. Also carry through a study on the composition of the fetal fluids, which we found the respectìvely he following results to amniotic and allantois liquida pH 8,19 and 7,13, protein 144,44 and 121.11, density 1007,5 and 1011,44, Creatinina 2.21 and 22.71, Albumina 0,28 and 0,13, alkaline Fosfatase 432,94 and 22,73, total protein 0,22 and 0,24, thus concluding the great similarity of the fetal fluids with urine. The gross shape of the umbilical cord in supplied to some interesting data such to them as the relation of size between the embryo and the umbilical cord which is of 2:1, another interesting data that are the relation of weight between the placenta and the umbilical cord is the ratio of 11,5:1. Microscopicolly the umbilical cord of the dog possess proper aspects as the confluente of the umbilicais veins occurring next the abdominal cavity, the walis of the veins (2) are thin and arteries (2) are muscular and thick, allantois duct are between situated the four vasas. The yoik sac presents great amount of capillaries, thin wall and yoik. (AU) | |
