Previous histochemical studies have demonstrated that collidine abolished the osmiophilia and the chromaffin reaction of the synaptic vesicles, an effect which was ascribed to the release of stored neurotransmitters. Other studies indicated a relationship between the inhibition of Na+,K(+)-ATPase and

Prior work using cell culture has shown that certain synthetic carotenoid derivatives are more effective than natural carotenoids in preventing photosensitized cell killing. These carotenoid derivatives are either cationic or are weak bases. We have now found that of one

The pKa of verapamil was determined by measuring the partition coefficient of verapamil between n-heptane and aqueous buffer solution at various pH values. The magnitude of the effects of ionic strength or temperature on the pKa of verapamil was in

The fluorescent properties of 2-hydroxy Nile red dye (HONR) proved to be highly sensitive to the basicity of hydrogen bond acceptors. Fluorescence quantum yields and fluorescence decay profiles were measured as the function of the concentration of organic nitrogen compounds

Rat pineal nerve endings contain a population of small and of large synaptic vesicles that are either electron lucent or have electron-dense cores. It has been reported that their osmiophilia is eliminated when collidine buffer is used in the fixation
