大豆、硒和螺旋藻对氟铝联合中毒大鼠血红蛋白的影响

目的 观察大豆、硒、螺旋藻对氟铝联合中毒大鼠血红蛋白(Hb)的改变.方法 84只SD大鼠,按体质量随机分为对照组、高铝组、高氟组、高氟铝组、高氟铝强化大豆组、高氟铝强化硒组、高氟铝加螺旋藻组,每组12只.对照组、高铝组的饲料含氟量为5.2 mg/kg,含铝量为6.8 mg/kg,其他各组的含氟量为106mg/kg,含铝量为19.7 mg/kg;对照组、高氟组的饮水含氟量为0.69 mg/L,含铝量为0.20 mg/L,其他各组的含氟量为0.69 mg/L,含铝量为90.2 mg/L).饲养90 d后,取全血测定Hb.结果 对照组、高氟组、高铝组、高氟铝组的Hb分别为(160.8±6.3)、(142.2±15.9)、(156.1±4.9)、(145.2±6.2)g/L.氟对Hb有影响(F=29.56,P<0.05).高氟铝组、高氟铝加大豆组、高氟铝加硒组、高氟铝加螺旋藻组的Hb水平分别为(145.2±6.2)、(150.7±17.7)、(156.8±14.5)、(154.5±17.8)g/L,虽然Hb水平有升高,但差异无统计学意义(χ2=3.304,P>0.05).结论 高氟能引起大鼠血红蛋白不同程度的降低,过量铝对大鼠Hb无影响;铝没有拮抗或加强氟中毒对大鼠Hb的干扰作用.大豆、硒和螺旋藻均对氟铝联合中毒大鼠Hb有升高趋势,但未见明显的拮抗作用.

Effects of soybean, selenium and spirulina on hemoglobin of rats intoxicated with fluorine and aluminium

Objective To observe the effects of soybean,selenium and spirulina on hemoglobin(Hb)of rats intoxicated with fluorine and aluminiums.Methods According to body weight,84 SD rats were randomly divided into control group,high aluminum group,high fluorine group,high fluorine-aluminum group,high fluorine-aluminium intoxicated rats strengthened with soybean group,high fluorine-aluminium intoxicated rats strengthened with selenium group and high fluorine-aluminium intoxicated rats strengthened with spirulina group,12 in each group.Rats in the control group and the high aluminum group were fed with feed containing 5.2 mg/kg of fluorine and 6.8 mg/kg of aluminum.In other groups,fluorine wag 106 mg/Kg and aluminum 19.7 mg/kg.Fluorine and aluminum concentration in the drinking water of the control group and the high fluorine group were 0.69 mg/L and 0.20 mg/L,respectively.In other groups' drinking water,these values were 0.69 mg/L and 90.2 mg/L,respectively.Ninety days later,Hb concentration of the whole blood was tested.Results Hb concentration of the control group,the high aluminum group,the high fluorine group,and the high fluorine-aluminum group were (160.8±6.3),(142.2±15.9),(156.1±4.9)and(145.2±6.2)g/L,respectively.Fluorine had an effect on the concentration of Hb(F=29.56,P<0.05).The Hb concentration of the high fluorine-aluminum group,the strengthened with soybean group,the strengthened with selenium group and the strengthened with Spirulina group were(145.2±6.2),(150.7±17.7),(156.8±14.5),(154.5±17.8)g/L,respectively.Though the concentration of Hb had increased,there was no significant difference between the four groups(χ2=3.304,P>0.05).Conclusions High-dose fluorine could cause varied decrease in the concentration of Hb.However,aluminum has neitherantagonistic effect nor synergistic effect on the Hb of fluorotic Rat.Soybean,selenium and Spirulina show a trend to increase fluorotic rat's Hb,but they has no evident antagonistic effect.
