Figure 2: Pictorial presentation of the activity of NP PMM formulation on promastigotes; A) Cs-Chs-Hb NP without drug as control. The cells were healthy, motile with high population density. B) Under the treatment of Cs- Chs Hb-PMM reduced number of cells with changed cell morphology and less motility were observed. C) Normal PMM with IC50 135 μM at 48 hrs. Cs-Chs Hb-PMM with IC50 was found to be 80 μM at 48 hrs.
