The roentgenologic diagnosis of chronic bronchitis: a reassessment with emphasis on parahilar bronchi seen end-on.

In an attempt to reassess the accuracy of the roentgenologic diagnosis of chronic bronchitis, we have studied the chest radiographs of approximately 300 men comprising roughly equal numbers of normal subjects and patients with chronic obstructive pulmonary disease (COPD). Emphasis has been placed on the thickness of bronchial walls visualized end-on in the parahilar zones, identified in roughly 80% of both groups. Step-wise discriminant analysis of six variables showed that the median estimate of bronchial wall thickness was of some value in discrimination.

[Evaluation of sectorial fluid movement by measurement of the global impedance of the body. Study during hemodialysis and during treatment with major diuretics].

During courses of haemodialysis or treatment with powerful diuretics, the clinician at the present time bases his actions on blood pressure levels which reflects blood volume and on weight variation which is dependent on water loss. The authors show, in studying variations in total body impedance at 5kHz and 1kHz and their ratio R, that there exists another method of observation which complements the basic notions provided by blood pressure levels and baseline weight. They were thus able to detect the possible formation of cellular oedema due to excessively rapid osmotic depletion. The method makes possible the evaluation of these sectorial fluid transfers when they occur, even though they are not evident clinically. This easy to use method is perhaps less rapid than the usual means of observation but is nevertheless more rational and provides information on electrolyte balance.

[Effect of rubratoxin B on the respiration of liver mitochondria in the rat].

The in vitro effect of rubratoxin B on the electron transport system of rat liver mitochondira was investigated. This mycotoxin depressed oxygen consumption in ADP-lacking mitochondira and in ADP-coupled mitochondria, using succinate or beta-hydroxybutyrate as substrats. Rubratoxin B is neither an oxidative-phosphorylation inhibitor nor uncoupling agent. Its effect is compared with aflatoxin B1.
