The Development Of Electrophysiological Techniques Allowing "In Situ" Measurement Of Electrical Changes Within Smooth Muscle Cells Of Mesenteric Micro-Vessels, William J. Willems

Master's Essays (1922 - )

The primary objective or this study is essentially to acquire further knowledge of the factors involved in the nervous and humoral control of vascular smooth muscle tone. The relative importance of the nervous and endogenous vasotropic humoral control or vasomotor tone under normal conditions as well as under conditions or hypotension can be evaluated, at least in part, by observing the electrical activity occurring in single vascular smooth muscle cells of the mesenteric microcirculation. This thesis describes: 1) the development of electrophysiological methods for the measurement of such activity in ''in situ" micro-vessels with circulation and innervation intact, and 2) …

Effect Of Between-Meal Eating On Stomach Emptying Time, Bernice Peterson

Loma Linda University Electronic Theses, Dissertations & Projects

As yet there is little agreement among health workers as to whether the practice of between-meal eating is harmful, beneficial, or indifferent in its influence on health. Studies which have been done heretofore on between-meal eating have been concerned with the effects on growth, appetite, daily nutrient intake, regularity, body metabolism, overweight, work efficiency, and dental caries. It appears that the possible physiological effects of between-meal eating have been only partially explored. The problem of this study was the effect of eating between meals on stomach emptying time.
