Fig. 4. The level of OFQ/N-IR was increased in the hippocampus of rats sensitized to cocaine.

Fig. 4

Rats were injected with saline or cocaine (20 mg/kg, i.p.) once daily for three days and sacrificed on day 8. Brain regions were isolated, homogenized and assayed for the level of OFQ/N-IR as described under legend to figure 2. Data are mean (±SEM) of 6 rats/group. *indicates a significant increase as compared to saline group (p<0.05).
