Abstract:
Objective To study the relationship between the complete blood count (CBC) and coal‐buring caused fluorosis of fe‐male rats .Methods Female SD rats were randomly divided into three groups :control group ,medium‐fluorine group and high‐fluo‐rine group .Rats in each exposed group were fed with fodder containing different proportions of corn dried by burning coal from flu‐orosis endemic areas to establish coal‐burning fluorosis model (fluoride of fodder were 47 .8 mg/kg and 96 mg/kg) .The corn of control group′s fodder was collected from non endemic areas (fluoride was 5 .2 mg/kg) .At 60 days ,120 days and 180 days ,the tail vein bloods were analyzed with automated analyzer .Results Compared with medium‐fluorine group ,the WBC of high‐fluorine group decreased at 60 d and 120 d(P<0 .05) .Compared with control group ,the RBC of fluoride treated groups decreased at each time point (P<0 .05) ,especially at 120 d .At 60 d and 120 d ,the Hb ,HCT and MCV decreased(P< 0 .05) .At 180 d ,only the MCV of high‐fluorine group increased obviously(P<0 .05) .At 120 d ,the Hb ,HCT of fluoride treated groups were less than those at 60 d and 180 d (P<0 .05) .The MCV of high‐fluorine group was same as above(P<0 .05) .At 180 d ,the MCV of medium‐fluo‐rine group decreased less than that at 60 d (P< 0 .05) .The MCH of fluoride treated groups increased at each time point (P<0 .05) .At 120 d ,the MCH of medium‐fluorine group increased more than its at 60 d and 180 d (P<0 .05) .At 180 d ,the MCH of higher‐fluorine group increased than those at 60 d (P<0 .05) .Conclusion Fluorosis has varied influence on blood cell of SD rats , especially on red blood cell system .In the early and mid stages ,the coal‐buring caused fluorosis showed the small RBC high pigment anemia .In the late stage ,the coal‐buring caused fluorosis showed the big RBC high pigment anemia .
