[Total body washout (T.B.W.) in the rat. II) Instrumental and laboratory controls].

TBW can be performed even without help of a cardiopulmonary machine (CPM). Low temperature and Ht levels are compatible with cardiac, and cerebral electric activity. Such conditions may be reached only by perfusing cold liquids and utilizing the cardiac and respiratory activity of the animals, with no use of machines.

[Enzymatic changes in the lymph in the thoracic duct and right lymphatic duct during extracorporeal circulation in the dog (author's transl)].

The authors analysed the various enzymes in the lymph of the thoracic duct and the right lymphatic duct in a series of 15 dogs submitted to extracorporeal circulation, the experimentors noted a series of diffuse cellular lesions which involved transiently the main organs. This lesion seems only to occur at first; independent of the duration of the by-pass, probably due to hypoxia following the rapid and massive introduction of priming. Our conclusion from this research is that lymph analysis is more revealing for knowledge of enzyme behaviour than blood analysis.
