Abstract:
Objective To study the effects of fluorine and aluminum on index of hematologic tests of rats. Methods According to body mass,56 Wistar rats of 130-200 g were randomly divided into control,low-fluorine (F),middle-F,high-F,low-F + aluminum(Al),middle-F + Al,high-F + Al group,8 rats in each group were given a series of doses of fluoride and aluminum,which were (0 + 0),(100 + 0),(200 + 0),(300 + 0),(100 + 10),(200 + 10),(300 + 10)mg/L After 90-day intragastrie administration,blood samples were collected on eyes of rats to undergo blood routine test,including red blood cell (RBC),lymphocyte (LYM),platelet (PLT),hemoglobin (HGB),white blood cell (WBC),hematocrit (HCT),mean corpuscular hemoglobin (MCH),mean corpuscular-hemoglobin concentration(MCHC),mean corpuscular volume(MCV),and at the same time some blood biochemistry indicators related to functio ns of liver and kidney were determined such as aspartic acid aminotransferase(AST),alanine aminotransferase(ALT),alkaline phosphatase(ALP),Crea(Cr) and Urea. Organ coefficient of liver and kidney were calculated. Results The difference of RBC,HCT,MCV among all groups of rats was statistically significant(F = 3.202,3.316,2.915,P < 0.05). The RBC,HCT of the low-F group[(7.59± 2.40)×10~(12)/L,0.51±0.11],the middle-F group[(8.60±1.16)×10~(12)/L,0.55±0.05],the high-F group[(9.23± 0.60)×10~(12)/L,0.54±0.03],the low-F + Al group[(9.25±0.79)×10~(12)/L,0.53±0.04],the middle-F + Al group[(7.98±2.14)×10~(12)/L,0.49±0.08]and the high-F + Al group[(7.61±3.17)×10~(12)/L,0.49±0.16]were significantly higher than that in the control group[(4.46±3.10)×10~(12)/L,0.31±0.16,P< 0.05 or < 0.01)]. The MCV of the middle-F group[(64.06±6.51)fl],high-F group[(58.67±1.13)fl],low-F + Al group[(57.78± 1.57)fl]and the middle-F + Al group[(63.04±10.64)fl]were significantly higher than the control group[(78.54± 15.57)fl,P < 0.05 or < 0.01]. The difference of AST and Urea among all the groups of mrs serum was statistically significant(F= 2.847,5.549,P < 0.05 or < 0.01). The serum AST of low-F group[(399.00±54.99)U/L],the middle-Fgroup[(465.60±76.99)U/L],the high-F group[(465.80±75.41)U/L],the low-F + Al group[(346.00±69.26) U/L],the middle-F + Al group[(437.40±68.31)U/L]and the high-F + Al group[(403.00±30.61)U/L]were all significantly higher than that in the control group[(336.67±94.34)U/L,P < 0.05],and the high-F group significantly higher than the high-F + Al group(P < 0.05). The serum Urea of the middle-F group[(7.70±0.52)mmol/L],the high-F group[(8.44±1.30)mmol/L],the low-F + Al group[(7.83±0.62)mmol/L],the middle-F + Al group [(7.73±0.47)mmol/L],and the high fluoride + aluminum group[(7.70±0.21)mmol/L]were all significantly higher than that in the control group[(6.55±0.50)mmol/L,P< 0.05 or < 0.01],and the low-F group was significantly lower than the low-F + Al group(P < 0.01),however the high-F group was significantly higher than that in the high-F + Al group(P< 0.05). The liver organ coefficient of the low-F group(2.94±0.36) was higher than the low-F + Al group (2.60±0.15,P < 0.05). Conclusions Fluorine and combination of aluminum and fluorine have toxicity on rats to a certain extent,including the proliferation of crythrocytes of rat,while the cell size gets smaller and the cell quality is deteriorated,meanwhile functions of liver and kidney are impaired. Aluminum shows different joint action in different concentrations of fluorine.
