A new and rapid titration of antimony(III) with potassium dichromate, with iron(II) as inductor.

The optimum conditions for the titration of antimony(III) with dichromate, and diphenyl-aminesulphonic acid as indicator, have been established. No iodine catalyst is used; the analytical reaction is based on an induced reaction with iron(II) as inductor. The titration can be done as easily as an iron(II) titration and the end-point is equally sharp. Titrations are possible with 0.01N solutions.

A double blind study of pimozide versus chlordiazepoxide in anxiety neuroses.

Eighteen patients diagnosed as anxiety states were treated under double blind conditions for a four week trial period with pimozide and chlordiazepoxide after randomisation. No significant differences could be demonstrated between chlordiazepoxide and pimozide as far as therapeutic efficacy or toxicity were concerned. Pimozide administered in a single daily dose was as effective as chlordiazepoxide administered in divided daily doses for the relief of anxiety symptoms.
