The experimentally observed pseudo-first order rate constant k is increased in the presence of DNA (18,19). This enhanced reactivity is a result of the formation of physical BaPDE-DNA complexes the dependence of k on DNA concentration coincides with the binding isotherm for the formation of site I physical intercalative complexes (20). Typically, over 90% of the BaPDE molecules are converted to tetraols, while only a minor fraction bind covalently to the DNA bases (18,21-23). The dependence of k on temperature (21,24), pH (21,23-25), salt concentration (16,20,21,25), and concentration of different buffers (23) has been investigated. In 5 mM sodium cacodylate buffer solutions the formation of tetraols and covalent adducts appear to be parallel pseudo-first order reactions characterized by the same rate constant k, but different ratios of products (21,24). Similar results are obtained with other buffers (23). The formation of carbonium ions by specific and general acid catalysis has been assumed to be the rate-determining step for both tetraol and covalent adduct formation (21,24).

Inorganic arsenicals such as arsenic trioxide, sodium arsenite, lead arsenate, calcium arsenate and Paris Green have been used for many years as soil sterilants. Organic arsenical herbicides, in which the organic group is bonded directly to the arsenic atom, have been used extensively for post-emergence control of weeds in cotton. Several of the more important herbicides are sodium cacodylate (monosodium dimethylarsenic acid) and sodium salts of methane arsonic acid. The latter compounds exist in two principal forms the monosodium salt (MSMA) at pH6.4 and the disodium salt (DSMA) at pH10.2.

Microscopic analysis. From each experimental group of specimens with incipient lesions, two specimens were selected randomly for microscopic analysis. Two adjacent slices (500 pm thickness) were prepared from each specimen with a diamond wire sectioning machine (model 3242, Well, Le Lode, Switzerland). The slices were fixed in 1.0 ml 4% paraformaldehyde, 1% glutardialdehyde in 0.1 M sodium cacodylate buffer, pH 7.4, for one week. One slice of each pair was subsequently demineralized in 2.0 ml 0.1 M acetic acid, 2.5% glutardialdehyde, pH 4.0. 

Specimens were post-fixed in 1% OSO4 in sodium cacodylate buffer, dehydrated in ascending alcohol solutions, and embedded in Epon LX 112. Semi-thin sections (1.0 pm thickness) were cut with a diamond knife and stained with Richardson s dye (contains methylene blue) or PAS-reagent. Micrographs were made with an Olympus New Vanox microscope. 

TABLE 11.1. Association Constants of Various Nucleic Acids with Neomycin. From top to bottom, various polynucleotides with their conformational preference (B- to A-form) are listed in 10 mM sodium cacodylate, 100 mM NaCl, 0.1 mM EDTA, pH 6.8. RNA targets that have previously been shown to bind neomycin are also listed. These targets are examples of RNA secondary structures that show high-affinity binding to aminoglycosides. Solution conditions for RNA targets vary as shown...
