    Notes: Cet article examine comment les calculateurs modernes servent ou pourraient servir en comptabilité nationale, soit pour ľutilisation des comptes, soit pour leur préparation.Du premier point de vue ľauteur insiste ďabord sur la complexité croissante des comptes nationaux qui rend difficile leur usage à partir de la forme classique de tableaux imprimés et tend à rendre nécessaire leur transcription sous forme de cartes perforées, cequi permettra de faire à la machine un certain nombre de travaux élémentaires sur les comptes.On peut également penser que les calculateurs permettraient des sondages rapides sur certains éléments des comptes en cours de préparation.Enfin, les utilisations des calculateurs électroniques pour ľanalyse des comptes, ľétude des modèles de projection et leur résolution sont bien connues.En ce qui concerne ľutilisation des calculateurs pour la préparation des comptes ľauteur montre que, étant donné le caractère imparfait du système statistique dans de nombreux pays, les comptes économiques des années passées sont en partie préparés àľaide de véritables modèles qui permettent de passer des données de base aux comptes et qui peuvent dans certains cas être résolus àľaide de calculateurs électroniques.Là oùľinformation statistique est meilleure, des éléments des comptes peuvent être calculés directement par agrégation des données élémentaires. On peut donc penser qu'une époque viendra où la plus grande partie des comptes nationaux sera préparée àľaide de machines électroniques à partir des données de base.On peut alors imaginer un monde où les transactions élémentaires seraient enregistrées au moment où elles seraient réalisées, rendant ainsi entièrement automatique la préparation des comptes nationaux. Mais alors les machines pourraient réunir les modèles de préparation et les modèles ďutilisation des comptes. Ľétape intermédiaire que constitue la préparation et la publication des comptes sous la forme actuelle deviendrait alors inutile.

    Notes: Abstract. Drought resistance in terms of plant production under conditions of drought stress was previously defined for several spring wheat (Triticum aestivum L.) varieties. Four varieties, differing in their drought resistance by this definition, were compared in their physiological responses to water stress, as induced by polyethylene glycol 6000 in the growth medium.Drought resistance was associated with osmotic adjustment, total root mass production under stress, maintenance of some stomatal permeability under stress, and maintenance of turgor at a given level of drought stress, by either osmotic adjustment or elevated plant water potential.Drought resistance was not associated, in this experiment, with plant top growth under stress or non-stress conditions, maximum leaf area per plant, plant transpiration, and total root mass production under non-stress conditions.

    Notes: Abstract: This study examined the effect of streptozotocin diabetes of 5 weeks duration on the profile of slow orthogradely transported radiolabelled protein in rat sciatic motoneurones. The diabetic rats showed a retardation of the tail of the slow-component profile. This selective retardation was unaffected by treatment with an aldose reductase inhibitor, although this treatment reduced the accumulation of sorbitol and prevented the depletion of myo-inositol in the sciatic nerves of the treated diabetic rats. Other groups, treated with myo-inositol, had normal or elevated sciatic nerve myo-inositol levels in the presence of accumulated sorbitol. The axonal transport profiles from both control and diabetic myo-inositol-treated groups gave normal tail velocities but an altered shape such that retardation of the tail of the profile may have been present in both. The study concludes that rats with 5 weeks streptozotocin diabetes show retardation of the velocity of the most slowly transported proteins in sciatic motoneurones, and that this defect is not linked to the polyol pathway.

    Notes: Summary The effects of orally-administered myo-inositol have been compared with those of an aldose reductase inhibitor on acute neurological defects in experimentally diabetic rats. Three groups of streptozotocin-treated diabetic rats (50mg/kg, IP) together with three groups of age-matched controls (saline, IP) were compared. One pair of groups (control and diabetic) were untreated for 3 weeks, another pair of groups received daily oral myo-inositol (667 mg/kg) and the third pair received an aldose reductase inhibitor (ICI 105552; 50 mg·kg-1·day-1, orally). The untreated diabetic group showed statistically significant deficits in accumulation, proximal to 24 h sciatic nerve constrictions, of choline acetyltransferase activity by comparison with untreated controls (2.8±0.4 versus 5.1±0.4nmol acetylcholine ·h-1·nerve-1; p〈0.001). The untreated diabetic rats also showed a fall in motor nerve conduction velocity of 6.2±0.7 m/s which was statistically significant (p〈0.001). Treatment of the diabetic group with myo-inositol prevented the development of both defects of axonal transport and conduction velocity; both measurements were similar to those of the myo-inositol treated control rats. Likewise the diabetic rats which received aldose reductase inhibitor showed prevention of both defects. Nerves from untreated diabetic rats showed marked sorbitol accumulation and a statistically significant reduction in myo inositol content by comparison with the untreated controls (sorbitol, 1.56 ±0.22 versus 0.8±0.01 and myo-inositol, 1.47±0.10 versus 2.3±0.10 nmol/mg; p〈0.001). Treatment of the diabetic rats with myo-inositol elevated the myo-inositol levels in nerve (3.05±0.22 nmol/mg) without affecting nerve sorbitol levels. Treatment of diabetic rats with aldose reductase inhibitor also normalised nerve myo-inositol (2.75±0.20 nmol/mg) and reduced nerve sorbitol (0.08±0.01 nmol/mg). These findings are consistent with the suggestion that both treatments prevent the development of the two functional defects by normalising the nerve myo-inositol content.

    Notes: Résumé Nous avons mesuré l'activité spontanée de rats mâles et femelles recevant des rations contenant 10%, 25% et 60% de protéine et 29% de graisses non-saturées ou 31% de graisses saturées. Les rats ont été maintenus isolés dans des cages à stabilimètre 6 jours de suite. On a comparé les données obtenues pendant les 3 derniers jours. On n'a pas trouvé de différences significatives dans l'effet des différents régimes, ni pour les mâles ni pour les femelles.

    Notes: Résumé On a examiné l'élevation de la glycémie chez les rats des 2 sexes après administration orale de sucrose. Une sécrétion de glucose semble prendre place en même temps que l'absorption de cette substance. On suggère un mécanisme basé sur l'interaction du glucagon, du glucose-6-phosphate et de l'insuline suivant l'administration de sucre. Les expériences témoins semblent éliminer la possibilité que ces résultats soient dus au stress.
