Abstract:
:To explore the mechanisms mediating the effects of acute morphine on the immune system, effects of ganglionic blockade with chlorisondamine on acute high dose morphine-induced alterations in blood lymphocyte proliferation, white blood cell counts, spleen lymphocyte proliferation and splenic natural killer (NK) cell cytolytic activity were examined in male Sprague--Dawley rats. Two hours after morphine (30 mg/kg, s.c.) administration, blood lymphocyte proliferation (ConA) was decreased 85%; this effect was antagonized by chlorisondamine (5 mg/kg, i.p.). Notably, however, such morphine exposure did not significantly decrease splenic lymphocyte proliferation, although depression of NK cell activity was also evident and appeared to be chlorisondamine-sensitive. Immune effects of morphine 1 h after treatment were somewhat different. In this case, blood lymphocyte proliferation decreased and plasma levels of corticosterone increased, with ED(50) values of 2.2 and 7.8 mg/kg, respectively. Splenic lymphocyte proliferation and NK activity were also significantly depressed in the 1-h exposure paradigm, but only after administration of 30 mg/kg morphine. These results indicate that chlorisondamine blocks the effects of relatively high doses of morphine on blood lymphocyte activity and indicate that blood lymphocyte proliferation is more sensitive to effects of acute morphine exposure than splenic lymphocyte proliferation, NK cell cytolytic activity and activation of the HPA axis.
