Resumo

Background: The emergence of the NUDE and SCID immunosuppressed mice lineages generated knowledge on various mechanisms of lymphocyte maturation and human autoimmune diseases. Information on haematological and biochemical parameters of these lineages is still scarce, making it impossible to infer homeostasis by comparing data, or to detect genetic influences on the parameters for these species. Haematological and biochemical tests were carried out on Balb/c NUDE and C57BL/6 SCID mice of both sexes, aiming to analyse the presence of genetic influence on possible variations of such parameters and to verify reference values for both lineages.Materials, Methods & Results: One hundred and forty mice (Mus musculus) of the Balb/C NUDE and C57BL/6 SCID lineages were used in the present study. The animals were previously anesthetized, the blood collection procedure was performed by cardiac puncture and the samples were collected in the presence of heparin and intended for haematological and biochemical evaluation, under standardized conditions. The haematological evaluation consisted of red blood cell count, leukocyte counts, platelet counts, haematocrit, haemoglobin concentration, mean corpuscular volume (MCV), and mean corpuscular haemoglobin concentration (MCHC). The quantified biochemical parameters were: urea, creatinine, alanine aminotransaminase (ALT), aspartate aminotransaminase (AST) and alkaline phosphatase (ALP). While analysing the obtained data, it was possible to observe that only females presented divergences (P < 0.05) in the red blood cell series, in haemoglobin and in mean haemoglobin concentration (MCH). Regarding the analysis of the white blood cell series, females only presented differences (P < 0.05) in the leukocyte count. For males, there were variations (P < 0.05) in the counts of leukocytes, eosinophils, lymphocytes and neutrophils.[...](AU)
