Figure 4: Effect of Intraperitoneal (i.p.) injection of dendrosomal curcumin (DNC) in rats chronically treated with morphine on the expression of naloxone (2 mg/kg, i.p.)-induced jumping. Rats receiving DNC with morphine (DNC/Nal, n=6) were compared with the ones pretreated with vehicle (Carrier/Nal, n=7). Ordinate represents the number of rats. * P < 0.05, chi-square test.
