Abstract
Preservation of the property of semipermeability of cell appendages in the brain (which is responsible for shrinking) during exposure to hypertonic buffer at various times after death was investigated in experiments on rats. Membranes of the appendages were found to retain the property of semipermeability even 48 h after death. Prefixation of cadaver material in glutaraldehyde has no effect on the sensitivity of the appendage membranes to the osmotic strength of the surrounding solution.
