Critical Studies on the Determination of the Thyroid Secretion Rate in Cold-adapted Animals

Languages : en
Pages : 42
Book Description
There is ample evidence in the literature showing that cold adaptation in mammals can be accompanied by increased as well as by decreased thyroid activity. Measurement of thyroid secretion rate by determining the amount of L-thyroxine required to bloc the thyroidal I131 release, according to Perry's method, revealed that the thyroxine requirement of 6 degrees C-acclimated rats was twice as high as that of controls (5.5 = 0.7 micrograms/100g/day against 2.73 = 0.3 micrograms /100g/day for the controls). The requirement of the white rats acclimatized to cold outdoors during the winter on the other hand, was less than in the controls (1.8 micrograms/100g/day). The larger amount of thyroxine found in the feces of the 6 degrees C-acclimated rats (5.75 = 0.3 micrograms/day as compared to 2.84 = 0.4 micrograms/ day for the controls), the similar rate of urinary elimination of I131 in both groups, and the greater fecal elimination of the same isotope in the 6 degrees C-rats indicates that the greater requirement for thyroxine in these animals is at least partly due to increased fecal loss of the hormone.

Recognition and Alleviation of Distress in Laboratory Animals
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309108179
Category : Science
Languages : en
Pages : 137
Book Description
Scientific advances in our understanding of animal physiology and behavior often require theories to be revised and standards of practice to be updated to improve laboratory animal welfare. This new book from the Institute for Laboratory Animal Research (ILAR) at the National Research Council, Recognition and Alleviation of Distress in Laboratory Animals, focuses on the stress and distress which is experienced by animals when used in laboratory research. This book aims to educate laboratory animal veterinarians; students, researchers, and investigators; animal care staff, as well as animal welfare officers on the current scientific and ethical issues associated with stress and distress in laboratory animals. It evaluates pertinent scientific literature to generate practical and pragmatic guidelines. Recognition and Alleviation of Distress in Laboratory Animals focuses specifically on the scientific understanding of the causes and the functions of stress and distress, the transformation of stress to distress, and the identification of principles for the recognition and alleviation of distress. This book discusses the role of humane endpoints in situations of distress and principles for the minimization of distress in laboratory animals. It also identifies areas in which further scientific investigation is needed to improve laboratory animal welfare in order to adhere to scientific and ethical principles that promote humane care and practice.
