Analysis of Skin

The discoloring is likely to be caused by the photoreduction of silver chloride and/or silver phosphate in the skin. X-ray dispersive analysis of skin and other tissues reveals that the granules consist of silver complexed with sulfur and/or selenium. The photoreduced deposits are not removed by the body, and there are no clinical means of removing them.

To assess the types of data that may be used for QSAR analysis of skin permeabihty, refer to the reviews of Geinoz et al. (2004), Moss et al. (2002), and Vecchia and Bunge (2004b). There has been a wide variety of types of skin permeabihty data used for QSAR modeling. However, most data sets tend to be relatively small for QSAR development, typically between 5 and 20 compounds. In addition, it must be pointed out that most usable data were pubhshed from the 1960s to the 1980s. Because of the small number of individual data in data sets, it is appropriate to...

At the present time, extracts from some forty-five species of dendrobatid frogs have been examined, but detailed analyses have been carried out and published for only about one-half of these species. Sites of collection of various species of Phyllobates and Dendrobates for analysis of skin extracts are shown in Figs. 1 and 2. The five species of the genus Phyllobates all contain batrachotoxins (797, see Table 3). Certain Phyllobates species also contain pumiliotoxins and histrionicotoxins (797, unpublished results). The some thirty species of the genus Dendrobates whose skin extracts have been examined contain only the simpler dendrobatid alkaloids, that it is the pumiliotoxins, the histrionicotoxins, the gephyrotoxins, and related compounds 80, 187-190, unpublished results see Table 22). As yet, dendrobatid alkaloids have not been positively identified in skin extracts from ten species of a third genus of dendrobatid frogs, the usually cryptically colored Colostethus.
