Re: Water content of a cell ?

Dear Michael,

Re your recent posting. I have done some work with Neuntron activation
analsyis of breast tissues. I used freeze-drying technique to prepare the
tissues. I computed the wet/dry ratio of weight and it came out to be
mean=2.37, median 4.52, range=2.85-5.5.  For normal breast tissue,
median=1.91, range 1.4-3.4. This gives some idea on the water content of
cells, tho indirectly.

You could refer to my papers:

Ng KH, Bradley DA, Looi LM, et al Differentiation of elemental composition
of normal and malignant breast tissue by instrumental neutron activation
analysis. Appl Rad Isot 1993; 44:511-6.

Ng K H, Bradley DA, Looi LM. Elevated trace element concentrations in
malignant breast tissues. Brit J Radiology 1997 April (in press).
