PG - 211-4 AB - Exposure to either the dialyzed urine preparation (<500 Da) or the remaining substances (>500 Da) did not induce expression of Fos-immunoreactive cells in the mitral/tufted cell layer of the accessory olfactory bulb (AOB), whereas exposure to a mixture of these preparation did induce expression. These results suggest that a combination of low and high molecular weight substances is necessary for the increases in Fos-immunoreactivity in the AOB.
