The present study aims are investigating the effects of oral administration of AgNPs on some blood the parameters to show potential of toxicity of AgNPs as tool therapy and diagnosis. In this study, 20 healthy male and female rats were used. Randomly, rats were divided into 5 groups depending on the period variable respectively; AgNPs-treated rats' groups for a period of 3 days in concentration 0.2 and 0.4 gm/kg B.W, while the second period after 20 and 30 days after treatment with concentration 0.08 and 0.008 gm/ kg B.W. In addition to a control group. A Manual method was used to measure Hematological parameters. Rats treated with AgNPs showed the significant P<0.05 decrease in Hemoglobin, Packed Cell Volume, Red Blood Cells. Also, Mean Corpuscular Volume; Mean Corpuscular Hb and Mean Corpuscular Hb Concentration. Platelets levels and White Blood Cell Count were After the administration of AgNPs, a protective effect on hematopoietic levels and on Red Blood Cell morphology were shown respectively as it is assessed by Leishman stained blood smears resulted in ovalocytosis at the dose 0.4 gm/kg body weight, while at the dose, 0.08 gm/kg showed echinocytes, acanthocytes, tear drop, stomatocyte and codocyte (target RBCs). Thus, it is concluded that oral administration of AgNPs caused a decreased in the level of Hb concentration, PCV, RBC, MCV, MCH, MCHC, but increase PLTS and WBCs. It means that AgNPs has a toxic effect on blood.
