Fetal Whole-Body Fluid, Cardiovascular And Endocrine Dynamics : Computer Analysis Of Regulatory Mechanisms, Peter Stuart Gold
Fetal Whole-Body Fluid, Cardiovascular And Endocrine Dynamics : Computer Analysis Of Regulatory Mechanisms, Peter Stuart Gold
Loma Linda University Electronic Theses, Dissertations & Projects
The dynamics of transcapillary fluid and protein distribution and endocrine regulation of cardiovascular function were studied in chronically instrumented fetal sheep during the third trimester. Average experimental changes in vascular pressures, blood volume, plasma hormone concentrations, hematocrit and plasma protein concentration were analyzed using mathematical modeling and parameter optimization techniques in order to determine values for the major parameters which regulate fluid, protein and endocrine dynamics and to determine endocrine dose-response relationships to changes in cardiovascular function. The hormones which were considered are arginine vasopressin (AVP), angiotensin II (AII), epinephrine (EPI) and norepinephrine (NE). Vascular disturbances which were considered include …
A Semiquantitative Analysis Of The Chorda Tympani Taste Pathway In The Rat Brain With The 2-Deoxyglucose Method, Charles L. Hardison
A Semiquantitative Analysis Of The Chorda Tympani Taste Pathway In The Rat Brain With The 2-Deoxyglucose Method, Charles L. Hardison
Loma Linda University Electronic Theses, Dissertations & Projects
This thesis is based on a semiquantitative analysis of four nuclear relay centers [nucleus tractus solitarius (NTS), parabrachial nucleus (PBN), ventroposteromedial nucleus (VPM), gustatory neocortex (GNC)] in the chorda tympani nerve pathway. Metabolic changes were examined by the 2-deoxyglucose method in which one chorda tympani nerve was chemically stimulated and its contralateral side lesioned. Coronal sections of four taste centers were prepared for autoradiography and Nissl staining. Densities of the autoradiograms were determined by means of a video based image processor. Relative differences in the optical density ratios of the stimulated versus lesioned nuclear grey matter areas to white matter …
