| Primaquine and chloroquine are used for the treatment of malaria; evidence from the literature suggests that these drugs may induce oxidative stress. In this study we investigated the effects of primaquine and chloroquine on oxidative damage and DNA damage in brain, liver and kidney of rats after 7, 14 and 21 days of administration. Our results demonstrated that primaquine causes DNA damage in brain after 7, 14 and 21 days, and in liver after 7 and 14 days. Moreover, primaquine increases TBARS levels in the kidney and protein carbonyls in the brain after 14 days, and decreases protein carbonyls in the liver after 7 days. Whereas chloroquine causes DNA damage in the kidney after 7 and 14 days, and in the liver after 14 and 21 days, increases TBARS levels in... |

| The aim of this work was to study the effect of antimalarial drugs on the bioavailability of 99mTc-MDP in rats. Mefloquine (MQ) and artemisinin (AM) were administered in two treated groups (T) and sorbitol in control group (C) for 7 days. Then, 99mTc-MDP was injected in all groups and %ATI was calculated. A significant increase of %ATI in MQ group, from C to T, occurred in spleen (0.35±0.10to0.58±0.13), liver (1.69±0.28to3.31±0.07) and blood (0.79±0.17to2.09±0.53). The %ATI increased significantly in AM group:femur (2.76±0.59to5.98±0.70), liver (1.69±0.28to4.59±0.68), lungs (0.29±0.05to6.22±0.86), spleen (0.35±0.10 to0.86±0.15) and blood (0.79±0.17 to4.65 ±0.74). A significant decrease of %ATI occurred in MQ group:bladder (0.75±0.07to0.26±0.05), stout... |
