Plasma renin activity, plasma aldosterone and distal urinary acidification in diabetics with chronic renal failure.

The renin-angiotensin-aldosterone system and the acidification capacity of the renal tubule were studied in 13 diabetic patients with chronic renal failure. As a whole, the group showed hyporeninaemic hypoaldosteronism (HH). Studied alone, 12 of the 13 patients presented the requirements for HH. This group showed hypercholaemic hyperkalaemic metabolic acidosis with a disturbance in renal acidification which may be classified as Type IV renal tubular acidosis. The results of this group were compared to those of another two groups; one of diabetic patients without chronic renal failure and the other with chronic renal failure (C Cr less than 40ml/min); both were seen to show different behaviour to that of the group affected by the two processes.

[Right ventricle with double outlet and intact interventricular septum. Report of 1 case and review of the literature].

Double outlet right ventricle with an intact interventricular septum is an exceedingly rare malformation. Only six other cases have been found in the world literature. The clinical, electrocardiographic, radiological and anatomical features of this condition were reviewed on the occasion of the diagnosis of a new case. Cardiac catheterisation and angiography performed in only one other case is not definitive in the presence of mitral atresia.

Independent temporal expression of two N-substituted aminoacyl-tRNA hydrolases during the development of Artemia salina.

Encysted embryos of the crustacean Artemia salina contain an enzymatic activity which hydrolyzes N-acetylphenylalanyl-tRNA to N-acetylphenylalanine and tRNA. The enzyme apparently does not hydrolyze other free or N-substituted aminoacyl-tRNAs. The levels of this enzyme do not significantly change during embryonic and early larval development. In contrast, an unspecific hydrolase active on several N-substituted aminoacyl-tRNAs is practically absent in the encysted embryos and during embryogenesis and appears abruptly during larval development. The independent temporal expression of these two hydrolases during Artemia salina differentiation makes this organism siuitable for the study of the physiological role of these enzymes.
