Mechanisms of Systemic Regulation Acid-Base Regulation, Ion Transfer and Metabolism

Contents

This volume presents aspects of cellular mechanisms and generalized functions related to import and export of substance, intracorporeal transfer and maintenance of the overall status of animals: the regulation of ammonia detoxification by metabolic mechanisms, the renal elimination of organic acids as metabolic end products, the unmodified elimination of ammonia across cell membranes and epithelia; the effect of morphological changes in the branchial epithelium in response to varying external conditions on acid-base and ionic regulation in fish; the regulatory role of natriuretic peptide hormones for osmoregulation and hemodynamics in fish; the modulation of Na+ and K+ channels, as well as Na+/K+ and proton pump activity by intracellular pH in high resistance epithelia; the character of intracellular signals controlling ionic and acid-base regulation in avian nasal gland cells; behavioral body temperature reduction as an alternative and energetically advantageous approach to increasing oxygen supply under conditions of hypoxia; the metabolic and external detoxification in animals exposed to high levels of hydrogen sulfide.
