Water Structure Differences between Healthy and Cancerous Tissues
Kenneth S. Marsh, Thomas E. Wagner, Carlton F. Hazlewood
Abstract:
Magnetic
Resonance Imaging (MRI) is used to diagnose disease by presenting
differences between healthy and diseased tissues. MRI measures
response of water protons, and therefore differences in water
structure. Measurable differences in water structure between healthy
and cancer cells could potentially be exploited for improved treatment
if such differences resulted in altered solubility, drug action or
sensitivities to radiation. This study was designed to differentiate
Magnetic Resonance response between water in the extracellular matrix
and intracellular water in cancer and healthy cells. The discussion
concludes that water structure in cancer cells does differ from that in
healthy cells. This conclusion suggests that further studies on drug
action are warranted.

Water Structure Changes in Dilute Solutions of Physiologically Active Substances
Kenneth S. Marsh, Ki Brissey, Su-il Park
Abstract:
100
samples of dilute solutions of physiologically active substances were
prepared in water and a vicinal water solution which simulated cellular
interfaces. The solutions were then scanned in a medical MRI. The
results demonstrate that dilute solutions of these substances yield a
wide range of response suggesting that the water protons are
experiencing variations in the water environment. The vicinal
solutions exhibited more contrast than the corresponding bulk water
solutions. The suggestion is that physiologically active substances
modify water structure, especially interfacial water, and that this
influence on water structure is part of their physiological effect.
