Influência da esplenectomia na capacidade física em ratos

Abstract: Muitas das alterações fisiológicas provocadas IntroduçãoDesde a Antigüidade, em diversas culturas, como a hebraica, a grega e a romana, pressupunha-se que a retirada do baço melhorava o desempenho físico de soldados e atletas. Observações experimentais, porém sem critério científi-co, do século XIX e do início do século XX, reforçaram essa impressão. 1Por outro lado, estudos cientificamente conduzidos em diferentes animais, como o rato, o cão e o cavalo, mostraram que, em situações de esforço físico maior, o b… Show more

“…Benefits from an increase in the oxygen-carrying capacity of the blood must be set against an increase in blood viscosity, and thus a potential reduction in maximal cardiac output; the latter effect is compounded by a decrease of plasma volume, particularly when exercising in the heat. Observations on rats (Alberti, Petroianu, Riocha, & Caldeira, 2009;Caldeira, Rocha, Alberti, & Petroianu, 2005) compared splenectomised and sham-operated animals after 120 days of recovery. Somewhat surprisingly, the two groups of female animals showed no differences in physical performance, but the splenectomised males were able to run at 24 m · min -1 on a 12% treadmill slope for a longer period than control animals (10.2 vs. 6.7 min).…”

“…Its relevance is resides in the lack of knowledge of the the path of parenchymal circulation of this organ. Studies on the anatomy and splenic operations used findings from animals merged to humans' [4][5][6][7][8][9][10]22 . Although there are differences in the anatomy and physiology of the spleen between species, the knowledge gained in animal studies may assist in research on humans.…”

“…Within the spleen, arteries follow the trabeculae as trabecular arteries. Upon leaving the trabeculae, the arteries are surrounded by the white pulp in the form of a lymphocytes sheath (periarterial lymphatic sheat -PALS) [4][5][6][7][8][9][10] .…”
