Schematic representation of the most commonly used machines are shown in Figures 88 and 89. While, because of the large cross section of its extrudates, the reciprocating piston extrusion press (Figure 88a) is not normally used for pharmaceutical applications, screw extruders (Figure 88b and c) may find varied applications. However, the most commonly utilized equipment features differently arranged press rollers and perforated dies (Figure 89). If the extrusion bores are long and without relief counter-bores, relatively high densification...

Schematic representation of glucose (or galactose) transport by the enterocyte. Glucose binds to the receptor, facilitated by the simultaneous binding of two Na+ at separate sites. The glucose and Na" " are released in the cytosol as the receptor affinity for them decreases. The Na" " are actively extruded at the basolateral surface into the intercellular space by Na+,K+-ATPase, which provides the energy for the overall transport. Glucose is transported out of the cell into the intercellular space and thence to portal capillaries, both by a serosal carrier and by diffusion. (Reproduced with permission from G. M.
