Use of Dimethyl Sulphoxide for Preserving Corneal
SINCE it was discovered by Polge, Smith, and Parkes (1949) that living cells could be protected during freezing and thawing by adding glycerol to the storage medium, various substances and methods have been used in an attempt to achieve better results (Fleming,: 1952; Eastcott, Cross, Leigh, and North, 1954; Lovelock, 1954). We have been concerned with retaining the viability of corneal tissue ...

interactions which can be done when more structural information is available, but they do provide order of magnitude estimates of interaction strengths. Evidently, considerable rearrangement of charge driven by reduction significantly raises the effective dielectric. It seems likely that centres S-2 and FR-2 are apparently low-potential clusters merely because they are the middle clusters in th...
متن کاملCongenital malformations induced by dimethyl sulphoxide in the golden hamster.
Dimethyl sulphoxide (DMSO) is a relatively simple organic compound with a molecular weight of 78. It has been reported to be exceptionally non-toxic and has been used extensively in biological systems as a cell preservative, including freeze storage (Porterfield & Ashwood-Smith, 1962; Dougherty, 1962), and as a radioprotective agent against X-irradiation in mice (Ashwood-Smith, 1961). Recent cl...
متن کاملDimethyl sulphoxide protects cells against polypeptide toxins and poliovirus.
The effect of dimethyl sulphoxide and other cryoprotective compounds on the sensitivity of cells to polypeptide toxins and to poliovirus was tested. In the presence of these compounds, which all affect membrane fluidity, the cells were protected against the toxic proteins and against poliovirus. The large protection obtained was not due to reduced binding and endocytosis of the toxins. Apparent...
متن کاملDirect acoustic impedance measurements of dimethyl sulphoxide with benzene, carbon tetrachloride and methanol liquid mixtures
Ultrasonic impedance has directly been measured for various binary mixtures using a novel experimental technique. The mixtures are dimethyl sulphoxide with benzene, carbon tetrachloride and methanol at 295 K in different mole fraction ratios. The acoustic impedance of binary mixtures thus obtained was found to be in good agreement with those calculated from experimentally measured ultrasonic ve...
