Spectra of Positrons Lifetimes in Choose Gel Drugs

antiphlogistic drugs were investigated. The basic components in them were sodium salts of diclophenac and they difiered from one another with the chemical composition of other components. It was found that in all of the investigated spectra there occurred a component which testifled to the formation of positronium. The difierences in the values of ortho-Ps component lifetimes and their intensity can be attributed to the presence of ingredients modifying the efiects of the drug.
