Download or read book The Effect of Propylthiouracil on the Oxygen Consumption and Radioiodine Metabolism of the Frog Rana Pipiens in Winter written by Herman Matthew Meisner and published by . This book was released on 1961 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was undertaken to evaluate the physiological importance of the thyroid gland in the adult frog, Rana pipiens , in winter. Male frogs, weighing between 40-55 grams, were kept in running water and fed liver once a week. The thyroid gland was chemically inhibited by oral administration of 1.5 mg. of propylthiouracil three times a week. Oxygen consumption was measured weekly from December 21 to February 23 with volumetric respirometers at a temperature of 16+0.1°C. There were never any significant differences between the metabolic rates of the propylthiouracil inhibited frogs and the controls over the entire experimental period. Propylthiouracil effectively blocked the thyroid radioiodine uptake and blood conversion ratio, but after nine weeks, thyroid iodine stores were only reduced by one-half. This low secretion rate together with the fact that propylthiouracil did not alter metabolic rate suggests that the frog thyroid is of no calorigenic importance during the winter. The seasonal thyroid activity pattern was found to be characterized by a regression in the iodine concentrating capacity of the thyroid gland and blood from August to December, and reactivation towards the end of February. The appearance of monoiodotyrosine and diiodotyrosine in the circulation of Rana pipienS indicates that thyroidal deiodinase is unable to reduce iodotyrosines to iodide. It is postulated that there is an association between the presence of iodotyrosines in the circulation and the reduced thyroid function of poikilotherms.

Available in PDF, EPUB and Kindle. Book excerpt: In the middle and late 1960s, when it was clear that neuroendocrinology was established as a discipline in its own right, it occurred to us that auto biographical accounts of the pioneer work in this field by the major par ticipants would provide a highly interesting and informative account of his tory in the making. With the death of G. W. Harris in late 1971, and the loss thereby of an outstanding pioneer and personality in neuroendocri nology, it appeared to us to be even more urgent to undertake such a ven ture and collect as many stories as possible. The three of us agreed that initially we would limit our invitations to the senior investigators whose re search careers lay mostly behind them, with the hope that if this venture proved successful, we could ask younger and still very active researchers in neuroendocrinology to contribute to a subsequent volume. Most of those invited to write for this book agreed to do so, but regrettably there remain some notable absentees. The authors were requested to write a personal, and even idiosyncratic, account of the steps taken, and the motivation and drive that led them to develop their interest in the relationship between the brain and the endocrine system.
