A comparison is made of the staining results obtained with Nitro-BT and MTT-Co++ as acceptors when DPNH is the substrate in frozen sections of cold formol-calcium-fixed rat kidney (normal and following ligation of the blood vessels) and human liver containing lipofuscin granules. The kidney results are evaluated in terms of mitochondrial morphology seen after classical mitochondrial stains and in electron micrographs. It is concluded that, except for formazan deposition on lipid-aqueous interfaces, Nitro-BT staining indicates the intracellular localization of oxidative enzymes, at least at the level of light microscopy. In contrast, the use of MTT-Co++ is not reliable for such intracellular localizations. The deposition of the formazan of MTT-Co++ is determined in large part by physicochemical factors other than enzyme localization. Despite marked abnormalities of the mitochondria in cells of the ligated kidney, MTT-Co++ formazan is generally deposited in the same dotlike fashion as in cells of normal kidney.

Abstract. The waterfall effect describes the separation of charge by splashing at the base of a waterfall. Smaller drops that have a net negative charge are created, while larger drops and/or the bulk maintain overall charge neutrality with a net positive charge. Since it was first described by Lenard (1892) the effect has been confirmed many times, but a molecular explanation has not been available. Application of our fluctuation-correlation model of hydrophobic hydration accounts for the negative charge observed at aqueous interfaces with low permittivity materials. The negative surface charge observed in the waterfall effect is created by the preferential adsorption of hydroxide ions generated from the autolysis of water. On splashing, shear forces generate small negative drops from the surface, leaving a positive charge on the remaining large fragment. The waterfall effect is a manifestation of the general phenomenon of the negative charge at the interface between water and hydrophobic surfaces that is created by the preferential adsorption of hydroxide ions.
