An analysis of the edge damage of membranes studied in vitro.
A mathematical formula was developed for estimating the effect of membrane edge damage on the membrane permeability measured in vitro. It was assumed that in the chambers compressed against each other with identical force, the membrane edge damage depends on their radius and is characteristic for different tissues. Transport of rubidium and albumin across the human amnion and the rabbit mesentery was measured in two chambers with different active areas and this made it possible to estimate the extent of membrane edge damage.
