The entire field of information processing in medicine is today already spread out and branched to such an extent that it is no longer possible to set up a survey on relevant literature as a whole. But even in narrow parts of medical informatics it is hardly possible for the individual scientist to keep up to date with new literature. Strictly defined special bibliographies on certain topics are most helpful.In our days, problems of optimal patient scheduling and exploitation of resources are gaining more and more importance. Scientists are working on the solution of these problems in many places.The bibliography on »Patient Scheduling« presented here contains but a few basic theoretical papers on the problem of waiting queues which are of importance in the area of medical care. Most of the papers cited are concerned with practical approaches to a solution and describe current systems in medicine.In listing the literature, we were assisted by Mrs. Wieland, Mr. Dusberger and Mr. Henn, in data acquisition and computer handling by Mrs. Gieß and Mr. Schlaefer. We wish to thank all those mentioned for their assistance.

ABSTRACT Fractionation of monkey pituitary glands gave an oxytocin fraction in low yield which showed a counter-current distribution coefficient equivalent to that obtained with oxytocin from other species. Fractionation and chromatography of monkey vasopressin on carboxymethyl cellulose gave arginine-vasopressin of 60% purity, based on amino acid analysis and specific activity. Counter-current distribution on a small scale gave arginine-vasopressin of 89% purity. Reports by others that monkey pituitary glands contain arginine-vasopressin, based on pharmacological activities, are substantiated by the chemical data presented here.
