    Notes: Summary Over a 24-h period, Wistar rats from 4 litters, 6 to 9 days old, were given five intraperitoneal injections of a solution of 0.9% sodium chloride containing sodium fluoride (3 mg F/kg body weight). Within-litter controls were used. All rats were killed by decapitation 2 h after the final injection and the rat heads, cut sagittally, were processed for protein histochemistry. The intensity of staining of the protein in the enamel matrix of the upper jaw molar tooth buds was quantified using the two-wavelength method of microphotometry. A significant increase in the intensity of staining of fluoride-treated tissues over controls was observed with the histochemical methods specific for arginine (P〈0.01), tyrosine (P 〈 0.05), and cysteine (P〈0.05). Other histochemical methods specific for amino acid groups failed to show any significant difference between fluoride and non-fluoride-treated enamel matrix.

    Interactions of ligands with lithium picrate in dioxane (1990)
    Springer
    Journal of solution chemistry 19 (1990), S. 425-436 
    Details
    ISSN: 1572-8927
    Keywords: Complexation ; lithium picrate ; competition method ; dioxane ; ion binding ligands

    Topics: Chemistry and Pharmacology
    Notes: Abstract The interaction of several cyclic ethers, poly(ethylene glycol dimethyl ether)s, nitriles, esters and ketones with lithium picrate in dioxane at 25°C was investigated by means of a competition method using cross-linked poly(ethylene oxide) (PEO) as the insoluble ligand. The Langmuir-Klotz isotherm of LiPi binding to the PEO gel gave an apparent binding constant, K′, as a function of the concentration of added ligand. Plots of 1/K′ vs. the ligand concentration then yielded the formation constant, K L , of the ligand complex with LiPi. The results demonstrate that in dioxane one ligand molecule binds to LiPi. While there is some dependence on the Gutmann donicity number of the respective ligands, steric factors often play a dominant role in determining the value of K L . The results were compared with complexation data obtained on similar systems but by different methods.
