Estudio de la concentración de Na en sangre y eritrocitos: su distribución en las razas ovinas españolas

Abstract

According to the results of sortie authors on the distribution of Na and K in red blood cells and whole blood, in 1.831 sheep, distributed in 8 breeds with 14 ecotypes, we have studied the distribution of Na in whole blood, plasma and red blood cells, with their correlations between K. concentrations. We cannot find two kinds of Na in red blood cells, parallell y it is the same with K in red blood cells, perhaps because the breeds studied belong to LK type, in general. In the same way, we have analyzed the relations between Na to whole blood and red blood cells and we find out the conclusion that it is more efficient to analyze the values of Na red blood cells, to specify the different details in the distribution, because it is not possible to compare them with the characteristics of Na in the whole Mood. Finally, this study has demostrate the difficulty in characterizing the sheep"s breed studied, by means of the Na red blood cell}; parameter. Some correlations are evaluated and considered, for the parameters studied: Na whole blood: Na red blood cell, r=0,630 (P<0,001); Na red blood cell: packed red blood cells, r=0,279 (P<0,001), Na red blood cell: Na plasma, r-0,174 (P<0,001); Na; K red blood cell, r=0,167 (P<0,001) Na: K whole blood, r:=-0,488 (P<0,001); Na: K plasma, r= 0,261;; K whole blood: K red blood cell, x-0,970 (P<0,001).

En un totao de 1.831 ovinos, distribuidos en 8 razas con 14 ecotipos se estudia la distribución de Na en sangre total, plasma y eritrocitos y las concentraciones de K igualmente en sangre total, plasma y eritrocitos. No podemos establecer dos tipos de Na eritrocitarios, paralelamente a lo que ocurre con el K eritrocitario, posiblemente porque las razas ovinas estudiadas pertenecen al tipo LK, en general. Se comenta la dificultad de poder caracterizar por el parámetro "Na eritrocitario" dichas razas. Finalmente se estiman y discuten una serie de correlaciones entre los parámetros sanguíneos estudiados: Na sangre total; Na eritrocitario, r=0,630 (P<0,001) Na eritrocitario: V.H., r=0,279 (P<0,001); Na eritrocitario: Na plasmática, r=0,174 (P<0,001); Na : K plasmático, r=0,261; K sangre total:K eritrocitario, r=0,970 (P<0,001).
