Abstract:


Background & Objective: Age-dependent Organophosphates (OPs) toxicity is a controversial topic. The present study was designed to investigate the effect of the sub-acute exposure to diazinon (DZN), one of the main OPs insecticides, on the hematological alterations in adult and aged male rats.

Methods: For the aim of this approach, the adult and aged rats were administered with DZN (15 mg/kg, orally) for 4 weeks. Then, the blood samples were collected from the retro-orbital sinus for measuring red blood cell (RBC), hemoglobin (Hb), hematocrit (Hct), platelets (PLT), MCV (mean corpuscular volume), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin (MCHC).

Results: The obtained results indicated that DZN significantly decreased RBCs (4.93 ± 0.41), Htc (28.12 ± 1.21), Hb (10.31 ± 0.36), MCHC (30.51 ± 2.04), MCV (62.86 ± 2.58), and PLT (265.6 ± 34.81) values in the adult and aged rats versus the age-matched control rats. Moreover, RBC, Hb, and Htc levels decreased significantly in the aged rats versus adult rats. However, no significant differences were observed between MCHC, MCV, and PLT levels in adult and aged rats. Moreover, the MCH concentration did not change in any group. Additionally, DZN did not deteriorate the hematological alterations in the aged rats versus adult rats.

Conclusion: the present study showed that the toxicity of DZN is not associated with age. However, more studies should be conducted to confirm this finding.
