The experiments here recorded had three main objects :— ( a ) To investigate the effects of X-rays upon chick embryos of different ages irradiated in ovo (Part I). ( b ) To discover how far the destructive effect of radiation upon the tissues is due to a direct action of X-rays upon the individual cells, and how far it may be attributed to an indirect action resulting from physiological disturbance in the organism (Part II). ( c ) To determine if possible the nature of such indirect action (Part III). The authors are indebted to the Medical Research Council, by whom the expenses of these investigations were defrayed.

AbstractDuring the first half of the twentieth century, the mining industry in Britain was subject to recurrent disputes about the risk to miners’ lungs from coal dust, moderated by governmental, industrial, medical and mining bodies. In this environment, precise measurements offered a way to present uncontested objective knowledge. By accessing primary source material from the National Archives, the South Wales Miners Library and the University of Bristol's Special Collections, I demonstrate the importance that the British Medical Research Council (MRC) attached to standardized instrumental measures as proof of objectivity, and explore the conflict between objective and subjective measures of health. Examination of the MRC's use of spirometry in their investigation of pneumoconiosis (miner's lung) from 1936 to 1945 will shed light on this conflict and illuminate the politics inherent in attempts to quantify disability and categorize standards of health.

A avaliação da dispneia tem sido feita por meio de instrumentos como escala de Borg modificada, a escala de cores e a escala do Medical Research Council modificada (mMRC). O objetivo deste estudo foi correlacionar a frequência respiratória com a sensação de dispneia, através das escalas citadas, correlacioná-las entre si e verificar se o grau de alfabetização influenciou na resposta do paciente sobre a sensação de dispneia. Para avaliar o esforço físico utilizou-se o teste de caminhada de seis minutos. Este foi um estudo prospectivo, transversal e analítico-descritivo composto por 124 voluntários com diagnóstico de doença pulmonar. Para comparar as variáveis categóricas entre os grupos foram utilizados os testes Qui-Quadrado e exato de Fisher. Para comparar as variáveis contínuas foi utilizado o teste Kruskal-Wallis e para análise de correlação foi utilizado o coeficiente de correlação de Spearman. A idade média foi de 55,9 (± 13,08 anos), 14% eram analfabetos. Nos tempos de análise houve correlação positiva entre as escalas mMRC e Borg, r = 0,43, r = 0,61 e r = 0,55. Entre as escalas mMRC e Cores, observou-se correlação negativa. Concluiu-se que a frequência respiratória correlacionou-se com as três escalas. O grau de alfabetização não modificou a resposta do paciente em relação à sensação de dispneia.Palavras-chave: dispneia, fisioterapia, avaliação.
