Progression of foot pad swelling of different groups of BALB/c mice. The infected groups of mice received 5 × 10³ infective stationary phase promastigotes in the hind foot pad (s.c). Every week after challenge the foot pad swelling was measured using a caliper. The data are expressed in units (1 unit = 10^-2 cm of the net increase in foot pad thickness). The groups included Group P; infected but non-treated, Goup OP; infected treated with sessami oil (carrier of thalidomide), Group TP; infected treated with thalidomide in sessami oil, Group GP; infected treated with glucantime, Group TGP; infected treated with thalidomide and glucantime.
