Effectiveness of glass-ionomer surface protection treatments: a scanning optical microscope study.

Due to their complex setting reaction, glass-ionomer cements require careful control of hydration during the initial 48-hour maturation period. This in vitro study was designed to evaluate the efficacy of three surface protection treatments (copal varnish, unfilled bonding resin and a dentine bonding agent) in preventing water penetration into 40 restorations placed in recently extracted third molars. The sealing ability was analysed using confocal light microscopy to visualise dye penetration into the samples. The results indicate that the dentine bonding agent, in vitro, provides a comprehensive barrier to water movement.

Endoplasmic reticulum: the major contributor to the PDE peak in hepatic 31P-NMR spectra at low magnetic field strengths.

31P-NMR spectra of liver in vivo, subcellular fractions and model systems were acquired in order to characterise further the hepatic phosphodiester peak seen at low magnetic field strengths previously shown to be predominantly due to phospholipid bilayers. The data obtained in this study in vitro suggested that the phospholipid membranes of the endoplasmic reticulum provide the dominant contribution to this phosphodiester peak. Support for this hypothesis was provided by experiments on rats. Phenobarbitone, which is known to induce proliferation of the endoplasmic reticulum produced a considerable increase in intensity of the phosphodiester peak in liver spectra in vivo.
