Lo mismo sucedio en el caso del VGM y la CMHG (116,1-149,9 fL y 33,0-33,35 %, respectivamente).
[12] realizaron una evaluacion hematologica despues de la estimulacion con una cepa virulenta de Eimeria tenella en pollos inmunizados con la cepa atenuada o proteinas de esporozoitos de la cepa homologa y reportaron diferencias significativas (P<0,05) entre los tratamientos para la pp, lin, ht, eos, mon, y los indices eritrocitarios (VGM y CMHG).
where dp/dt is the pressure increase in time, t, at a steady state; V ([cm.sup.3]) is the downstream volume; T ([degrees]C) is the temperature; A ([cm.sup.2]) is the effective membrane area; p (cmHg) is the upstream pressure; and l (cm) is the membrane thickness.
The apparent dissolved [O.sub.2] permeation coefficient, [P.sub.L] [[cm.sup.3] (STP)cm/([cm.sup.2] s cmHg)], was determined using the following equation:
where K [[cm.sup.3](STP)/(A cm s cmHg)] is the peculiar electrode constant of the electrode rod; [i.sub.[infinity]] (A) is the amount of current in steady state of the permeate side; and [c.sub.1] and [c.sub.2] are the theoretical and experimental feed [O.sub.2] concentrations, respectively.
The apparent dissolved C[O.sub.2] permeation coefficient, [P.sub.L] [[cm.sup.3] (STP)cm/([cm.sup.2] s cmHg)], was determined using the following equation:
where dC/dt ([cm.sup.3](STP)cm) is the C[O.sub.2] concentration increase in time (i.e., [c.sub.1]-[c.sub.2]), V ([cm.sup.3]) is the cell volume of the permeate side, and p' (cmHg) is the partial C[O.sub.2] pressure.
The [P.sub.G] ([O.sub.2]) and [P.sub.G] (C[O.sub.2]) of the base membrane were 153 X [10.sup.-10] and 979 X [10.sup.-10] [cm.sup.3](STP)cm/([cm.sup.2] s cmHg), as shown in our previous study [19].
The pattern may be explained by the difference in permeability of the evolved gases (it was found that [N.sub.2] is less permeable than and C[O.sub.2] with PE ([N.sub.2] = 2.7 c[m.sup.3] mm/s c[m.sup.2] cmHg and C[O.sub.2] = 35 c[m.sup.3] mm/s c[m.sup.2] cmHg) (2) or by the differences in endothermic and exothermic reaction, which is explained in the next section.
