Abstract:
Objective To observe the effect of low arsenic sub-chronic exposure on blood routine test index in rabbits to pave a way for screening early injury of the low arsenic exposure. Methods Twelve healthy male rabbits were randomly divided into four groups. They were administrated with As at the concentration of 0(control), 10, 50 and 250 μg/L in the drinking water. Blood samples were collected from the vein of the ear edge in 8 weeks, and blood test routine including leukocyte (WBC), lymphocyte (LYM), lymphocyte percentage (LYM%), neutrophil (GRA), neutrophil percentage (GRA%), monocyte (MON), monocyte percentage (MON%), red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin content (MCH), mean corpuscular hemoglobin concentration(MCHC), RDW, platelets(PLT), mean platelet volume(MPV), platelet hematocrit(PCT) and platelet distribution width (PDW), were detected by the ABX-60 hemocyte analyzer. Results Compared with the control group, the WBC, GRA and GRA% increased in 0, 50 and 250 μg/L groups, but there was no significance(P > 0.05). PLT and MPV had a statistical significance in 4 groups(F = 4.07,4.20, all P < 0.05). Compared with the control group[(292.00±16.97)×109/L, (7.10±0.99)fL], PLT decreased in the 250 μg/L group [(221.33±22.50)×109/L] and MPV decreased in the 50μg/L group [(5.57±0.46)fL] significantly (P < 0.05). The other index didn't change obviously. Conclusions Sub-chronic low level arsenic exposure may lead to the change in the blood system. The blood routine test may be considered for early injury of the arsenic poisoning.
