HIGH AND LOW DENSITY WATER AND RESTING,ACTIVE AND TRANSFORMED CELLS

Resting and active states of cells are described in terms of the expectation, derived from experiments with aqueous polymers, that they contain two modified forms of water: high density, reactive, fluid water and low density, inert, viscous water. Low density water predominates in a resting cell and is converted to high density water in an active cell. It is proposed that switching from one state to another is an integral part of cellular function. When this ability is lost cells are transformed either to a state of rigor or to a hyperactive state in which they no longer depend upon external signals.     

SPHINGOLIPIDS AND PHOSPHOLIPIDS IN MICROSOMES AND MYELIN FROM NORMAL AND PATHOLOGICAL BRAINS

—Myelin and microsomes were separated from human cerebral white matter and cortex respectively using the technique of 15% caesium chloride and their sphingolipid and phospholipid contents estimated. Normal brains as well as cerebral material from cases of metachromatic leucodystrophy, Krabbe's disease and Tay-Sachs’disease were studied. Gangliosides were not present in normal myelin but were found in microsomes and in myelin from the pathological material. The ratio of cerebroside to sulphatide in myelin was 4 to 1 in normal, 1 to 20 in metachromatic and 7 to 1 in Krabbe's disease. The results in the human material are briefly discussed.
