Fibrinogen levels in mammals suffering from bacterial infections 总被引：3，自引：0，他引：3
In a retrospective survey of fibrinogen levels and neutrophil counts in 388 blood samples from mammals suffering from bacterial infection, the combined results of the two tests provided positive confirmation of infection in a greater percentage of samples than did the results of either test alone. In Perissodactyla, Artiodactyla and Proboscidea, the fibrinogen level was abnormal more often than the neutrophil count. It was concluded that a fibrinogen estimation is a valuable addition to routine haematological screening procedures in mammals. 相似文献

The stopped-flow technique has been applied to the determination of dissociation, phosphorylation, and bimolecular reaction constants for the inhibition of acetylcholinesterase by a potent organophosphate in the presence of a chromogenic substrate. The advantages of the method for inhibition studies are compared with those of an earlier spectrophotometric technique. 相似文献

Quanitative methods of assessing the architecture of small intestinal mucosa have been applied to biopsy material from normal dogs. Mucosal samples taken from four predetermined sites show that there are significant quantitative differences between the various levels of the small bowel. Animals of one year of age and older show no correlation between age or weight and mucosal dimensions. The significance of these findings, in relation to examination of biopsy material from cases of clinical small intestinal disease, is discussed. 相似文献

Histological sections from the small intestines of dogs showing clinical signs of small intestinal malabsorption have been examined using morphometric techniques. Weibel graticule measurements appear to be a useful adjunct to the subjective assessment of villus atrophy. Severe clinical signs of small intestinal malabsorption may be associated with a patchy distribution of lesions throughout the small bowel. 相似文献
