    Notes: The changes in central venous pressure (CVP) in patients who received ergometrine, oxytocin, ergometrine with oxytocin (Syntometrine), or no oxytocic drug in the third stage of labour have been compared. The results showed that there was a significant rise in central venous pressure after the administration of ergometrine and Syntometrine. When diazepam was given late in the first stage of labour to a group of patients who received Syntometrine during the course of delivery the changes in CVP were not significantly different from those of the control group. In addition, the administration of oxytocin in the management of the third stage did not produce a significant rise in CVP. The volume of blood lost was significantly reduced in all subjects by the use of oxytocic drugs.

    Notes: Abstract— The distibution of 14C in the brains of rats that had been given [U-14C]glucose (10μCi/100g body wt.) at 10 min before death was followed for 20 min post mortem. The results indicated that the input of glucose-carbon into the tricarboxylic acid cycle stopped instantaneously after death. Although the proportion (more than 40 per cent) of tissue-14C combined in the amino acids associated with the cycle did not change significantly, there was a characteristic redistribution of 14C within the amino acid fraction after death: significantly, the 14C content of glutamate decreased andthat of GABA increased. The GABA/glutamate specific radioactivity ratio which in vivo was 0-58, increased progressively in the first 5 min after death, reaching a value of 0-93. However, by 5 min the rise in the ratio stopped abruptly, although GABA accumulation continued at about half the initial rate beyond that time. These results indicated that GA BA formation is compartmented in the brain andpermitted the evaluation of certain kinetic parameters of the two compartments which could be distinguished under the experimental conditions. One of the compartments was evidently a summation of a number of subcompartments which had certain features in common, such as a low GABA flux relative to the amount of glutamate. The properties of the other compartment were compatible with those of nerve terminals functioning with GABA as the transmitter. This compartment contained about 2 per cent of the total glutamate, but the glutamate pool was labelled about three times more than the average. Further, this compartment accounted for about 50 per cent of the total GABA formation flux andcontained GABA in high concentrations (the probable values were about seven times the mean).

    Notes: Abstract— A small basic protein (mol.wt. 12,000), referred to as the P2 protein, was extracted with dilute acid from delipidated bovine root myelin and purified by ion exchange chromatography on cellulose phosphate. It appeared homogeneous on polyacrylamide gel electrophoresis. The P2 protein had a distinctly different amino acid composition than the larger basic protein (mol.wt. 18,000), referred to as the P1 protein, that is also present in peripheral nerve myelin. It contained relatively more hydrophobic residues and much less histidine and proline. The P2 protein conjugated with peroxidase was bound by lymph node cells and infiltrates in rabbits sensitized with whole bovine root myelin. No binding was evident with the bovine central nervous system myelin basic protein. Chemically and immunologically, the P2 protein appears to be specific to peripheral nervous system myelin. The isolated P2 protein produced mild clinical symptoms of experimental allergic neuritis, but no histological evidence of disease. It was suggested that the P2 protein is an important antigen for experimental allergic neuritis, and that its antigenic determinants are likely to be conformation-dependent.

    Notes: Changes are advocated in some of the definitions, units and notation current in electron diffraction. The purpose of those changes is to separate descriptions of properties of materials from the experiments intended to measure them, and to exhibit as clearly as possible the relationship between the differing properties of a material accessible in X-ray and electron work.

    Notes: With a Mach-Zehnder interferometer, salt concentration profiles were measured in a reverse osmosis system under natural convection with the membrane in a vertical position. The measured concentration profiles compared favorably with those predicted theoretically as long as the motion remained laminar. At large distances from the leading edge, however, the flow developed a wavy pattern, especially for bulk salt concentrations in excess of 0.1 moles/liter. As expected, whenever this motion became especially pronounced, the concentration of salt at the membrane surface was less and the production rate of fresh water greater than that predicted using the laminar analysis.
