Anatomic regions extension

Although it would be out of place to give here an extensive account of the surface anatomy of bacteria, current interest in the exact location of compounds in the anatomical components of cells, for example, in membranes, granules, mitochondria, and ribosomes, requires a reasonably precise description of the location of teichoic acids. In its turn, this requires an understanding of the main features of the outer regions of bacteria. Gram-positive bacteria possess a rigid cell-wall which is responsible for... 

Recently, Pershing reviewed much of the extensive validation of typical in vivo skin stripping techniques. Such variables as the test region anatomical site, individual investigator technique, adhesive systems and product dose, application, and removal techniques were discussed. It was concluded that careful validation of adequate removal of residual applied... 

The permeability of human skin can vary considerably according to anatomical location (Maibach et al., 1971). The phenomenon of regional variation also applies to chemical warfare agents. One of the most extensive investigations of regional permeability in humans was conducted with VX in the late 1950s (Sim, 1962). This study demonstrated that, for example, the skin of the scrotum is 350 times more permeable than that of the back of the hand (Figure 6).
