Resumo: |
Glucocorticoids are used in prenatal treatments to speed up the pulmonary development in cases of prematurity risk. The administration of glucocorticoids is commonly associated with change in the production and distribution of blood cells, hyperglycemia and change in carbohydrates metabolization in target-tissue, as liver. The present research has subjected to evaluate the effect of dexamethasone application in early and mid- pregnancy of rats over hematologic, biochemist and histochemistry parameters of the offspring. A Number of 12 albinic rats was divided in: group I rats treated with dexametasona 1 to 7 pregnancy day and with placebo 8 to 14 pregnancy day; group II rats treated with placebo 1 to 7 pregnancy day and with dexametasona 8 to 14 pregnancy day; group III rats treated with dexametasona to 1 to 14 pregnancy day with dexamethasone concentration reduction of 15% to each 2 days and group IV rats treated with placebo 1 to 14 pregnancy day. Decadron® commercial formularization was managed for intraperitoneal injection daily in the dose of 0.8mg/kg/animal. For analysis of the hematologic parameters and level of full blood carbohydrates, blood samples was taken for rats in 7, 14 and 21 pregnancy day and for the offspring in 5, 10 and 15 post-birth day. For assessment of offspring glycogen liver storage, histological sections were stained by Schiff’s Periodic Acid. The results of the present research point in respect to a time-dependent effect of dexamethasone administration during the pregnancy, leading to a distinct secular alterations in the hematology as lymphopenia, eosinopenia and neutrophilia at the moments of the administration, being reversible until the end of the pregnancy when performed in early third of pregnancy and changes in plasma levels of full blood carbohydrates in the matrices and offspring are more evident in the longest treatment. |
