Quantimet analysis of Pathlogical Changes of Blood Circulatory Disturbances in Rat / 中华创伤杂志

ABSTRACT

The pathological changes of blood circulatory disturbances of the rat lungs induced by blast or blast burn injuries were analysed quantitatively by quantimet 920. After infusion fixation with 40% formalin, the different relevant grey levels were viewed in four longitudinal sections of left and right lungs. The different greg levels corresponded with the severity of circulatory disturbancecs, espesially with the hemorrhage. Because various degrees of disturbances play different roles in the pathophysiological effect on the body, weight coefficinet 0, 1, 2, 4 were designed respectively according to the grey level, the sum of both all grey area of the lung and corresponding weight coefficinet indicates the value of the degree of circulatory disorder in the injuried lung. Thus the severity of the pathlogical changes could be estimated quantitatively.
