Number of pithed rats utilized in the six main sets and their subsequent division into the different groups (n = 5 each with no exception) used in the present study. The animals in set 1, set 2, and the first box of set 3 represent the control group animals (without ritanserin-pretreatment, n = 35). On the other hand, the second and third boxes of set 3, as well as sets 4, 5 and 6 represent the animals that were pretreated i.v. with 100 μg/kg ritanserin (n = 100)
