Novel Arsenic Nanoparticles Are More Effective and Less Toxic than As (III) to Inhibit Extracellular and Intracellular Proliferation of Leishmania donovani

Table 2

(a) Inhibition of parasite infection (at 37^°C for 24 hours). (b) Inhibition of parasite attachment (at 4^°C for 4 hours).

(a)

Sets	Total number of macrophages	Numbers of infected macrophages	Numbers of internalized parasites inside the macrophages
Control	500
2 M As-NP	500
0.1 M As (III)	500
1.0 M As (III)	500
2 M As (III)	500

values for number of infected macrophages and internalized parasites are 0.001 which is statistically significant.

(b)

Sets	Total number of macrophages	Numbers of infected macrophages	Numbers of attached parasites in the surface of macrophages
Control	200	52^#	68^#
2 M As-NP	200	22^#	23^#

values for number of infected macrophages and attached parasites are 0.0014 which is statistically significant.
