Pressure influences the rate of fibrin polymerization: decompression accelerates, compression decelerates.
We report here that the rate of fibrin polymerization is accelerated by decompression: the rate is essentially doubled by reducing the pressure by one-half (380 torr, 14.7 PSI or 1/2 ATM) and increased by 3.6 times with respect to the control at 25 torr (0.48 PSI or 1/30th ATM). We also report here that the rate of fibrin polymerization is decelerated by compression; at 5.2 X 10(5) torr (10,000 PSI or 680 ATM) polymerization is inhibited and/or reversed.
