    Notes: Summary This study examined the effects of two stabilised analogues of TRH, RX 77368 and CG 3509, in a rat cerebral ischaemia model produced by unilateral occlusion of the middle cerebral artery. The analogues were given intraventricularly after artery occlusion. The extent of the cortical ischaemia was evaluated after 10 days by somatosensory evoked potential (SEP) recording, followed by tetrazolium staining of brain slices for NADH-diaphorase activity. RX 77368 (2×10 μg; 15 min, 24 h) significantly improved the survival rate, protected the SEP and reduced the area of infarct. In contrast, neither a smaller dose of RX 77368 (2×3 μg) nor a 4 h delay in the treatment had any significant beneficial effects. Although CG 3509 (2×10 μg) resulted in an apparent improvement in survival, its overall effects were not statistically significant. The findings indicate that stabilised TRH analogues may have beneficial effects when given to animals with focal cerebral ischaemia.

    Notes: Summary This paper is concerned with our investigation into the effects of temperature on the liquid chromatography absorbance baseline. Measurements were made to quantify the effects in terms of wavelength and solvents. Five solvents commonly used in HPLC were investigated, methanol, propanol, hexane, heptane and acetonitrile. The alcoholic solvents were found to have a high absorbance sensitivity to temperature at wavelengths around their ‘UV cut off’ points. Possible mechanisms for this effect are discussed and include solvent impurity, density changes and inter-molecular bonding.

    Notes: Abstract The “Telecommunication Management Network” standard (ITU-T M.3010), the Network Magagement Forum “OMNIPoint” program, and many related developments are summarized. TMN and OMNIPoint are presented as a means to achieve integrated network management in the telecommunications industry by calling for all management systems to include an interoperable interface which permits each system to be integrated into a larger management hierarchy. By means of such interfaces, hierarchical integration of management systems can be achieved within the administration of a single service provider. Interoperable interfaces also make possible the interconnection of multiple service providers and the connection of customer to service provider, resulting in the possibility of industry wide integration of management infrastructures at all levels.
