Figure 2. Radioimmunoassay of AVP.

Figure 2

AVP levels were measured during mid-acquisition (5 days), late conditioning (10 days) of cocaine conditioning and during the drug expression session (day12). Black bars represent cocaine-conditioned subjects. AVP was measured from NAc tissue rich punches and is expressed as pg/ml of total protein. The up regulation of AVP peptide during conditioning confirms the up regulation of the mRNA in the arrays—except for mid-acquisition. No AVP levels were found in control subjects. There were significant differences between C Mid Acquisition and E Mid Acquisition (* p<0.05), between Late Acquisition and E Late Acquisition (### p<0.001), between C Expression and E Expression (+++ p<0.001). C= Control, E= Experimental.
