[Pathological modifications of the P wave due to probable primary changes in intra-atrial conduction].

Two cases of variable changes in ECG P oscillation not due, as is usually the case, to familiar cardiac or respiratory conditions suggested a review of the literature on the subject. It is concluded that these anomalies are the result of changes in the intra-atrial conduction of the stimulus through preferential ways or to aberrant atrial conduction. These are situations of no little practical interest because they may be precursors of major rhythm disturbances such as atrial flutter or atrial fibrillation.

[Echinococcal cysts of the adrenal glands. Review and diagnostic discussion].

Observation of an exceptional case of hydatid cyst of the suprarenal gland triggered an extensive review of the literature on the subject and an analysis of the disease from a historical-statistical, biological, aetiopathogenic, anatomopathological and clinical point of view. All these were analysed as an aid to diagnosis which is always difficult despite the many effective diagnostic tools now available. The difficulty derives essentially from the rarity of the condition and the fact that its clinical features often appear not to confirm or to underestimate the initial diagnostic suspicion.

Translational discrimination between embryonic and adult mouse globin mRNAs in the rabbit reticulocyte lysate system.

In the present study mouse adult (alpha, beta) and embryonic globin (x, y, z) mRNas are compared for their capacity of being translated in a micrococcus nuclease treated rabbit reticulocyte lysate. The results of these experiments indicate that: 1) alpha and beta adult RNAs are translated with a higher efficiency as compared to the alpha-like and beta-like embryonic mRNAs; 2) adult beta and embryonic beta-like messengers are translated more efficiently than their corresponding adult alpha and embryonic alpha-like messengers; 3) the alpha/beta synthetic ratio, both for adult and embryonic globins is highly dependent upon the concentration of globin mRNAs. For embryonic globins the ratio decreases from 0.21 at low mRNA concentration to 0.11 at high mRNA concentration. For adult globin mRNAs the alpha/beta chain synthetic ratio decreases from 1.4 to 0.9 within the same range of concentration.
