Study of the Information Dissemination Service--Health Sciences Library, State University of New York at Buffalo.

The Information Dissemination Service at the Health Sciences Library, State University of New York at Buffalo, was established June 1970 through a three-year grant from the Lakes Area Regional Medical Program, Inc. Analysis of two samples of user request forms yielded results which significantly substantiate findings in prior biomedical literature utilization studies. The findings demonstrate comparable utilization patterns by user group, age of material, journal titles, language, time to process request, source of reference, and size of institution.

Evaluation of Thyopac-3 test in the in-vitro assessment of thyroid function.

Thyopac-3, a new commercial test kit for the in-vitro assessment of thyroid function, has been appraised in a group of 411 patients. The Thyopac-3 test was found to be simple and rapid to perform and accurate in diagnosis. Of 117 patients shown to be euthyroid by other criteria, 5% had Thyopac-3 values outside the normal range (derived from a group of 135 normal patients), and 10 of 79 thyrotoxic and 4 of 37 hypothyroid patients had values within the normal range.In a direct comparison in 190 patients with the resin uptake test the Thyopac-3 test emerged very favourably in regard to diagnostic accuracy and was technically easier and quicker to carry out. There was a non-linear negative correlation between results from the two procedures.

The rabbit as a subject in behavioral research.

Domestic rabbits were exposed to a wide variety of variables employed in behavioral research. It was found that: (1) Although food could be used as a reinforcer, the long periods of severe deprivation required to reduce body weight made its use impractical. (2) Water was an efficient reinforcer in that it maintained high rates of behavior after 22 hr of deprivation. (3) Except that rates of responding were higher, fixed-ratio and variable-interval schedules of reinforcement produced patterns of behavior similar to those demonstrated by rats and pigeons. (4) Although the duration of the post-reinforcement pause was a function of the duration of the interval under fixed-interval schedules, scalloping, as defined as a gradually increasing rate of responding between reinforcement, was not evident. (5) When provided with the means to both turn on and turn off intracranial stimulation, the duration of the stimulation and the frequency with which it was turned on and off was a function of the intensity of the stimulation. (6) Electric shock could suppress behavior and maintain escape responding, but would maintain avoidance responding only in a few subjects.
