    Notes: Summary The plasma glucose, C-peptide and insulin responses to subcutaneously administered highly purified porcine, ‘semi-synthetic’ and ‘biosynthetic’ human isophane (NPH) insulin and diluting medium as control in normal male subjects were evaluated. Porcine and semi-synthetic human NPH insulins were administered at two dose levels of 0.15 and 0.30 U/kg body weight and biosynthetic human NPH at 0.15 U/kg body weight only. At the low dose level the three insulin preparations resulted in a similar maximal hypoglycaemic effect within 3–5 h after administration. However, over the remainder of the 11 h post-injection period, the plasma glucose level was lower after semi-synthetic human insulin. In contrast, at the 0.30 U/kg dose level, there was no difference in the early or late hypoglycaemic response between porcine and semi-synthetic human NPH insulins of equivalent pharmaceutical formulation. The clinical relevance of these findings needs further evaluation. The data suggest that for the ‘intermediate-acting’ NPH insulin preparations, both the species of insulin, nature and quantity of the retarding protein and their subsequent interaction may determine their time-action characteristics.

    Notes: Summary The fine structure of granular glycogen bodies (GGB) within the grey matter of the temporal cortex of 11 patients with Alzheimer's disease is described. GGB measure up to 50 μm in diameter and consist of densely packed α or β glycogen granules (never both), neither of which are membrane bound. They were noted in axons, both myelinated and unmyelinated (sometimes close to the dystrophic neurites of senile plaques), and also in other processes of indeterminate origin. Their appearance may relate to disturbances of axonal transport resulting from damage to terminals within evolving senile plaques.

    Notes: Abstract Objective: The gastrointestinal tonometer, which allows measurement of gastrointestinal mucosal CO2 and subsequent derivation of gut intramucosal pH (pHi), has been demonstrated to be a sensitive predictor of outcome following major surgery. Current theory suggests that the origin of the low pH may be hypovolaemia. This study was designed to compare the temporal sequence of changes in tonometric readings with invasive blood pressure, stroke volume, heart rate, lactate and arterial blood gas measurements during progressive haemorrhage. Design: Observational healthy volunteer study. Setting: Intensive care unit at University College London Hospitals. Subjects: Six healthy, medically qualified volunteers. Interventions: After obtaining baseline measurements, the subjects were progressively bled 25 % (range = 21–31 %) of their blood volume over a period of 1 h in two approximately equal aliquots. Equilibration was allowed for 30 min following the bleed, after which further measurements were made and the blood was then retransfused over 30 min. Measurements and main results: There was no consistent change in any of the haemodynamic variables other than gastric intramucosal CO2 : arterial CO2 gap (PiCO2− PaCO2) after removal of the first aliquot of blood, although five of the six subjects also demonstrated a fall in pHi. After removal of the second aliquot of blood, PiCO2− PaCO2 gap and pHi continued to indicate a worsening gastric intramucosal acidosis; stroke volume, as measured by suprasternal Doppler, demonstrated a marked fall, while all other variables measured had not altered consistently or to such a degree as to elicit a clinical response or cause suspicion of a hypovolaemic state. On retransfusion, all variables returned towards baseline. Conclusions: This study demonstrates the value of tonometry as an early monitor of hypovolaemia and highlights the shortcomings of other more commonly measured clinical variables.

    Description / Table of Contents: Résumé La convalescence de rats rachitiques, déficients en phosphate-vitamine D, s'accompagne d'une augmentation de deux à six fois, de l'excrétion de l'hydroxyle-proline urinaire. En utilisant le14C, cette augmentation semble dûe partiellement à une synthèsede novo plus élevée de peptides d'hydroxyle-proline (OHPr) par rapport à un groupe témoin de rats rachitiques. Il n'y a pas de différence significative en carbone radioactif ainsi que le démontre l'excrétion de14CO2 au cours de la période de guérison, par rapport à des témoins rachitiques. Il semble y avoir une synthèse augmentée d'un collagène, qui ne se laisse pas extraire, dans le tissu epiphysaire de rat rachitique, en voie de guérison. L'afflux de phosphate semble stimuler et fausser les voies de synthèse protéique de l'os, en plus de son rôle dans la minéralisation.
    Abstract: Zusammenfassung Die Heilung der Phosphat-Vitamin D-Mangelrachitis bei Ratten wird von einer zweibis sechsfachen Zunahme der gesamten Hydroxyprolin-Ausscheidung im Urin begleitet. Ein Vergleich mit rachitischen Kontrollratten mittels14C zeigt, daß diese Zunahme zum Teil auf eine höhere de novo-Synthese von Hydroxyprolin-(OHPr)-Peptiden während des Heilens zurückzuführen ist. Es besteht kein signifikanter Unterschied im markierten Kohlenstoff-Pool, wie dies durch die14CO2-Ausscheidung bei genesenden im Vergleich zu rachitischen Ratten nachgewiesen werden kann. Das Epiphysengewebe der genesenden rachitischen Ratte zeigt eine erhöhte Synthese von nicht extrahierbarem Collagen. Phosphat-Sättigung stimuliert und verändert die Proteinsynthese im Knochen, abgesehen von der Rolle, die sie bei der Mineralisation spielen kann.
    Notes: Abstract The healing of phosphate vitamin-D-deficient rachitic rats is accompanied by a two to sixfold increase in total urinary hydroxyproline excretion. In14C studies this increase is shown to be partly due to a higher rate ofde novo synthesis of hydroxyproline (OHPr) peptides in healing as compared with a control series of rachitic rats. There is no significant difference in the labelled carbon pool as shown by14CO2 excretion in the healing compared with rachitic rats. There is evidence for increased synthesis of non-extractable collagen from the healing rachitic rat epiphyseal tissue. Phosphate repletion is seen to stimulate and alter protein synthetic pathways in bone apart from the role it may play in mineralisation.

    Notes: Based on amino-acid sequence homology, it is predicted that ribosomal protein L14 is a member of a recently identified family of structurally related RNA-binding proteins. To verify this, the gene for Bacillus stearothermophilus L14 has been cloned, and the protein has been purified and crystallized. The crystals are in space group C2 with cell dimensions a = 67.0, b = 32.7, c = 49.4 Å, and β = 101.8°, and there is one molecule in the asymmetric unit (Vm = 2.0 Å3 Da−1). They are of high quality, and a native data set has been collected to a resolution of 1.6 Å, with an Rmerge of 5.3%.
