Aspects Of Anuran Metabolism: Effects Of Chronic Hypoxia On Maximal Oxygen Uptake Rates And The Fate Of Lactic Acid, Thomas Charles Solberg
Aspects Of Anuran Metabolism: Effects Of Chronic Hypoxia On Maximal Oxygen Uptake Rates And The Fate Of Lactic Acid, Thomas Charles Solberg
Dissertations and Theses
Some aspects of anuran metabolism are examined, with special emphasis on possible limitations to aerobic metabolism and the effect of chronic hypoxia acclimation on maximal rates of aerobic metabolism and the metabolic fate of lactic acid accumulated after anaerobic metabolism.

Anuran Activity Energetics, Scott R. Landrey
Dissertations and Theses
This thesis presents two separate experiments concerning aerobic and anaerobic amphibian energetics. The first study (Part I) investigates differential alterations in the kinetics of the anaerobic enzyme lactate dehydrogenase, in nine species of anurans with varying natural histories. The second study (Part II) studies changes in different anaerobic and aerobic physiological parameters in a single species (Rana catesbeiana) after six weeks of chronic exercised, unexercised-captive and for field frogs. The common theme of these two experiments involves the potential for physiological changes due to environmental stress. Part I examines different species to infer a possible evolutionary relationship to …
Factors Affecting Thyrotropin Secretion In Superfused Rat Anterior Pituitary Cells, Frederick Scott Bartlow
Factors Affecting Thyrotropin Secretion In Superfused Rat Anterior Pituitary Cells, Frederick Scott Bartlow
Dissertations and Theses
The use of static in vitro pituitary cultures has been indispensible for examining the regulation of anterior pituitary hormone secretion. While the static cultures have shown the effects of various chemical stimulators of hormone secretion, the dynamics of such secretion has not been assessed before in vitro. The in vitro superfusion method, which partially stimulates in vivo physiologic conditions, allows for the observation of the dynamics of pituitary hormone secretion.
