摘要： A study of the digestive system of skid-row alcoholics at the termination of a drinking episode revealed varying degrees of physiologic disturbance of one or more of the digestive organs. These functional alterations were usually minor and were frequently transient. The disturbances noted were: (1) reductions in gastric hydrochloric acid; (2) variations in urine uropepsin values above and below normal; (3) increases in serum lipase and amylase suggestive of subacute pancreatitis; (4) hepatomegaly accompanied by minor and transient alterations of liver function tests; (5) transient minimal deficits of gallbladder filling and emptying, and (6) frequent abnormalities in the tests for intestinal absorption of xylose and potassium iodide.

摘要： In the human, the antagonistic, extensor-flexor system of the leg is an example of a common type of neurophysiological feedback system. After a brief introduction to the neuroanatomy and physiology of this feedback system, the paper formulates transfer functions from temporal response data available in the literature. A feedback stability analysis, based on the extension of Nyquist's stability criteria to multiple-loop systems and utilizing flow-graph techniques, demonstrates the stable behavior of the system. Expressions are given relating the sensitivity of the system to variations in muscle response and Golgi tendon organ (tension receptor) response. By considering the events taking place at synapses and end-plates during "isometric tension-small knee angle excursion" conditions as stationary stochastic processes, an external "noise" input to the system is given, whose spectrum is derived from the statistics of a shot-process representation of these events. The paper concludes with some correlations between the analytical results and clinical syndromes. © 1959 University of Chicago.
