Analysis and distribution of Pb and Cd in different mice organs including liver, kidney, spleen, heart and blood were evaluated after treatment with different aqueous concentrations of garlic (12.5-100 mg/l). Atomic absorption spectrometry (AAS) was used for analysis of Pb and Cd in these organs. Treatment of Cd-Pb exposed mice with garlic (12.5-100 mg/l) reduced Pb concentrations by 44.65, 42.61, 38.4, 47.56, and 66.62% in liver, kidney, heart, spleen and blood respectively. Moreover, garlic reduced Cd levels by 72.5, 87.7, 92.6, 95.6, and 71.7% in liver, kidney, heart, spleen and blood respectively. The suppressed immune responses in mice pretreated with Cd-Pb mixture were reversed by 48.85, 55.82, 81.4 and 90.7 in the presence of 100, 50, 25, and 12.5 mg/ml of garlic extract.
