papers appear to report the same experiment. There are more details
in the 1994 paper.
There was a significant difference between exposed animals and controls in the frequency of leakage of albumin into the brain. The frequency was independent of the SAR level for values < 2.5 W/kg, but rose significantly for SAR values above that level. There was no significant difference between continuous and pulsed microwaves. There was no leakage of fibrinogen.
