Available in PDF, EPUB and Kindle. Book excerpt: The relationship of local skin temperature and the onset of sweating to the local cutaneous blood flow was studied in the forearm and calf. T HE PURPOSE OF THE INVE TIGATION WAS TO APPRAISE THE POSSIBLE RELATION OF SWEAT GLAND ACTIVITY TO THE CUTANEOUS VASODILATATION WHICH HAS BEEN ATTRIBUTED TO BRADYKININ OR TO INTRACRA IAL TEMPERATURES. The onset of sweating was not marked by any apparently related increases in the rate of cutaneous vasodilatation. On the contrary, the onset of sw ating was follo ed often by a stabilization or ev n a decrease in the l vel of cutaneous blood flow. The relations of the latter to the local skin temperature were complex, particularly in the forearm. There appeared to be additional unidentified influences, possibly vasomotor, operating on the skin vessels during transitional phases in the relation of skin temperature to blood flow. (A UTHOR).

Download or read book Local Sweating and Cutaneous Blood Flow During Exercise in Hypobaric Environments written by Margaret A. Kolka and published by . This book was released on 1987 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of acute hypobaric hypoxia on local sweating and cutaneous blood flow was studied in four men and four women (follicular phase of menstrual cycle), who exercised at 60% of their altitude-specific peak aerobic power for 35min at barometric pressures (Pb) of 770 Torr (sea level), 552 Torr (2,596 m), and 428 Torr (4,575 m) at an ambient temperature of 30 deg C. We measured esophageal temperature (Tes), mean skin temperature (T sk, 8 sites), and local sweating (ms) from dew-point sensors attached to the skin at the chest, arm, and thigh. Skin blood flow (SkBF) of the forearm was measured once each minute by venous occlusion plethysmography. There were no gender differences in the sensivity (slope) or the threshold of either ms/Tes relationships for the three regional sites decreased with increasing altitude, although these differences were not significant between the two lower PBs. The slope of SkBF/T was reduced in five of the eight subjects at 428 Torr. Enhanced body cooling as a response to the higher evaporative capacity of the environment is suggested as a component of these peripheral changes occuring in hypobaric hypoxia.
Download or read book Cutaneous Blood Flow and Local Sweating After Systemic Atropine Administration written by Margaret A. Kolka and published by . This book was released on 1986 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Localized cutaneous vasodilation (flush) is seen following systemic atropine administration. To verify calculated enhanced dry heat loss with actual changes in cutaneous blood flow, four men were studied in both control and atropine experiments during moderate exercise. Esophageal temperature (Tes) and arm sweating (ms) by local dewpoint were measured continuously. Skin (forearm) blood flow (FBF) was measured twice each minute by venous occlusion plethysmography. Injection of atropine (2 mg) caused an increased sensitivity in FBF to Tes with no change in the vasodilator threshold. An elevated Tes onset for sweating occurred with no change in the sensitivity of ms to Tes. No elevation in either forearm or Tsk occurred before the onset of vasodilation, however, both mean skin (Tsk) and local arm temperatures were higher in the atropine experiments after 15 minutes of exercise. Systemic atropine resulted in higher cutaneous vasodilation at the same core temperature with the local skin temperature following passively. The effect of systemic atropine in simulation of increased cutaneous vasodilation is suggested to result by a combination of central and local response which may be mediated through the release of vasoactive substances. Keywords: Anticholinergic drugs; evaporative heat loss; skin blood flow; thermoregulation.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes current information concerning the regional adjustments of cutaneous vascular tone during body heating. Most of the data to which reference is made were obtained in the writer's laboratory. The importance of the local skin temperature in accounting for the cutaneous vasodilatation is emphasized and the role of bradykinin is discounted. The regional differences in the onset, temporal sequence, and extent of the cutaneous vasodilatation are not explained by reference to a central thermostat in the hypothalamus.

Download or read book Thermal and Moisture Transport in Fibrous Materials written by Textile Institute (Manchester, England) and published by Woodhead Publishing. This book was released on 2006-10-30 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transfer of heat and moisture through textiles is vital to the manufacture and design of clothing, technical and protective textiles. Continued advances in textile processing technology, the growth of manufactured nonwovens and the application of nanotechnology have resulted in a wealth of research in order to characterise the behaviour of these materials. Thermal and moisture transport in fibrous materials provides a comprehensive guide of the technological developments and scientific understanding in this area. The first section summarises the structure, geometry and stereology of fibrous materials. The fundamentals of wetting and its dynamics are also discussed. Part two analyses thermal and liquid interactions in textiles and offers insights into the thermodynamic behaviour of moisture as well as heat and moisture coupling. The book concludes with chapters on the human thermoregulatory system, interfacing between fibrous materials and the human body and innovative computer modelling simulations. Thermal and moisture transport in fibrous materials is an essential reference for all those involved in the textile industry, especially those concerned with the design and manufacture of technical textiles and protective clothing.

Download or read book Thermotherapy for Neoplasia Inflammation and Pain written by M. Kosaka and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the multitude of different forms of thermotherapy in connection with aspects of thermal physiology and cell biology. The aim is to elucidate the scientific background of therapeutic actions and to promote effective new applications at the beginning of the 21st century. Significant to these purposes is cooperation between experts in the fields of thermal biology, hyper thermic oncology, rheumatology, and balneology, as represented by the editors. Emphasis has been placed on a balanced choice of contributions, in the hope that this will enable the reader to draw helpful connections between the principles and prac tice of thermotherapy. It is apparent that a wealth of published data exists concerning thermotherapy on the one hand and thermal physiology on the other. However, in the former field empirical aspects of therapeutic usefulness prevail, while in the latter, aspects of basic science are in the foreground. Accordingly, the sources where published data may be found are quite different and as a consequence many findings of potential mutual interest published in medical journals have gone unnoticed by readers of physio logical journals, and vice versa. It is hoped that this book will bridge the gap and encourage researchers' efforts to integrate the available knowledge to attain optimal coordination of clinical and theoretical aspects.
Download or read book Temperature Regulation in Humans and Other Mammals written by Claus Jessen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do mammals manage to maintain their body temperature within the same narrow range in environments as different as polar regions and hot deserts? This advanced text describes the morphological features and physiological mechanisms by which humans and other mammals maintain their body temperature within a narrow range despite large variations in climatic conditions and internal heat production. Its 19 chapters deal with the physics of heat exchange with the environment, and the autonomic and behavioural mechanisms available to control the loss and production of heat. The neuronal basis of temperature regulation and current concepts of the central nervous interface between temperature signals generated in the body and control mechanisms are examined in detail. This book is of invaluable help for undergraduates, postgraduates, teachers, physicians and scientists.

Available in PDF, EPUB and Kindle. Book excerpt: Since the first edition of this book was published in 2004, to much acclaim, the pace of innovation in the field of skin metrology has increased and various new technologies have become available. This new, revised edition reflects these advances by presenting the current theory and practice of noninvasive investigation and measurement of the skin and its appendices in health and disease. The first, extensive part of this authoritative work is devoted to the physiology and metrology of the various structural components of the skin. Skin functions and their measurement are then discussed in detail, with sections on mechanical protection, photoprotection, barrier function, immune function, thermoregulation, and sensory function. In addition, careful consideration is given to skin disease rating and skin maps, and a unique list of physical and biological constants and units is provided. Not only is this new edition the first comprehensive, practical handbook in this domain – it will also serve as a manual of skin physiology and collates anatomical, functional, and physical quantitative data that would otherwise be arduous to retrieve because of their dispersal throughout the literature. It will prove a valuable resource for dermatologists, cosmetologists, bioengineers, physiologists, pharmacists, and all others who deal with the skin in their work.
