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.

Known as the bible of biomedical engineering, The Biomedical Engineering Handbook, Fourth Edition, sets the standard against which all other references of this nature are measured. As such, it has served as a major resource for both skilled professionals and novices to biomedical engineering. Biomedical Signals, Imaging, and Informatics, the third volume of the handbook, presents material from respected scientists with diverse backgrounds in biosignal processing, medical imaging, infrared imaging, and medical informatics. More than three dozen specific topics are examined, including biomedical signal acquisition, thermographs, infrared cameras, mammography, computed tomography, positron-emission tomography, magnetic resonance imaging, hospital information systems, and computer-based patient records. The material is presented in a systematic manner and has been updated to reflect the latest applications and research findings.

The evolution of technological advances in infrared sensor technology, image processing, "smart" algorithms, knowledge-based databases, and their overall system integration has resulted in new methods of research and use in medical infrared imaging. The development of infrared cameras with focal plane arrays no longer requiring cooling, added a new dimension to this modality. Medical Infrared Imaging: Principles and Practices covers new ideas, concepts, and technologies along with historical background and clinical applications. The book begins by exploring worldwide advances in the medical applications of thermal imaging systems. It covers technology and hardware including detectors, detector materials, un-cooled focal plane arrays, high performance systems, camera characterization, electronics for on-chip image processing, optics, and cost-reduction designs. It then discusses the physiological basis of the thermal signature and its interpretation in a medical setting. The book also covers novel and emerging techniques, the complexities and importance of protocols for effective and reproducible results, storage and retrieval of thermal images, and ethical obligations. Of interest to both the medical and biomedical engineering communities, the book explores many opportunities for developing and conducting multidisciplinary research in many areas of medical infrared imaging. These range from clinical quantification to intelligent image processing for enhancement of the interpretation of images, and for further development of user-friendly high-resolution thermal cameras. These would enable the wide use of infrared imaging as a viable, noninvasive, low-cost, first-line detection modality.

Many advances have been made in the field of thermoregulation in the past few years. These include our understanding of Fever, which is now considered not simply a rise in deep body temperature foHowing infection, but just one aspect, though perhaps the most easily measured, of the Acute Phase of the Immune Response. Classification and identification of the Cytokines and the availability of recombinant material has greatly aided this research. Similarly, our understanding of the Hypothalamo-Pituitary Adrenal Axis has altered our way of thinking about temperature regulation. Of importance are the problems associated with adverse climatic conditions and survival, and the problems encountered by the neonate and the hibernator. At the biochemical level, our knowledge of the control of heat production and the role of brown adipose tissue is rapidly advancing. All these issues and many others were discussed at a Symposium 'Thermal Physiology 1993' held in Aberdeen, Scotland in August 1993 under the auspices of the Thermal Physiology Commission of the International Union of Physiological Sciences. Six main aspects of the subject of temperature regulation are included in this book, namely, Fever (including the Acute Phase of the Immune Response and Thermoregulatory Peptides), Neurophysiology of Thermoregulation, Neonatal Thermoregulation, Mechanisms of Heat Production, Ecological and Behavioural Thermoregulation, and Emerging Themes in Thermoregulation.
