摘要:

SUMMARY:(i) An account of the changes in calibre of vessels, Irradiated with various doses of γ‐rays from60Co., has been described, from direct microscopic observations of vessels,in vivo, using the Sandison Clark ear chamber technique.(ii) Attention has been drawn to the essential dynamic character of the reactions, with particular reference to changes in normal vasomotion.(iii) The changes have been analysed, by certain pharmacological techniques designed to test the functional integrity of irradiated vascular smooth muscle.(iv) Descriptions are given of “immediate” vascular dilation the primary roentgen erythema and the secondary roentgen reaction, and the factors responsible are analysed.(v) The observations have been made on vessels “isolated” from epithelial proximity, and the indirect effects of epithelial damage on vascular reactions are discussed.(vi) The fallacy which underlies the conception of radiation, erythema as a static dilation of blood vessels, is discussed, in view of the

摘要:

SUMMARY1The Scientific Committee on the Effects of Atomic Radiation established by the United Nations General Assembly accepts the view that the irradiation of human beings, and especially of their germinal tissue, has certain undesirable effects.2Information received so far indicates that, in certain countries (Sweden, United Kingdom, United States of America) by far the most important artificial source of such irradiation is the use of radiological methods of diagnosis and that this may be equal in importance to radiation from all natural sources. It is possible that such radiation may be having a significant genetic effect on the population as a whole.3The Committee is fully aware of the importance and value of the medical use of radiations but it wishes to draw the attention of the medical profession to these facts and to the need for a more accurate estimate of the amount of exposure from this source. The help of the medical profession would be most valuable to make it possible to obtain fuller information on this subject.4The Committee would be particularly grateful for information through appropriate governmental channels on ways in which the medical irradiation of the population can be reduced without diminishing the true value of radiology in diagnosis or treatment.
