摘要
为研究不同剂量氟化钠对獭兔的影响,试验建立獭兔氟中毒模型并对獭兔血液、骨骼、肝脏、肾脏等器官氟含量进行测定。试验獭兔日龄(30±5)d,体重(1.1±0.2)kg,数量24只,分为3组:对照组、试验Ⅰ组(10mg/(kg·d)氟化钠组)和试验Ⅱ组(20mg/(kg·d)氟化钠组),试验共100d。结果表明,试验第100天测定的骨骼和牙齿氟含量在各组之间均差异显著(P<0.05),且骨骼和牙齿的含氟量随时间和摄入氟剂量的增加而递增;肾脏和肝脏氟含量在各组之间均差异不显著(P>0.05);试验Ⅰ、Ⅱ组间血液氟含量差异不显著(P>0.05),但都与对照组差异显著(P<0.05)。氟化钠作为氟化物来源可用来建立獭兔自然状态氟中毒症,骨骼和牙齿累积氟能力强,血液、肝脏和肾脏累积氟能力弱。本试验为进一步研究獭兔氟中毒及其防制提供了理论参考。
In order to study the influence of different doses of sodium fluoride on rex rabbit,rex rabbit fluorosis model was established and the fluorine contents of blood,bone,liver,kidney and other organs in rex rabbit were examined to provide a theoretical reference for the further research.Rex rabbits（age（30±5）days,weight（1.1±0.2）kg）were divided into three groups：Control group,test group Ⅰ（10 mg/（kg·d）NaF group）and test group Ⅱ（20 mg/（kg·d）NaF group）.The tests lasted 100 d.The results showed that,on the 100 th day,fluoride contents of bone and tooth were significantly different（P〈0.05）,and they were positively correlated with the time and intake of fluoride;The fluoride contents of kidney and liver were slightly different（P〈0.05）,and they were not significantly different between both test groups（P〈0.05）.The fluoride contents of blood were not significantly different between group Ⅰ and group Ⅱ（P〈0.05）,but both had no significant changes compared with control group（P〈0.05）.Sodium fluoride as a fluoride source could be used to simulate the natural state of rex rabbit fluorine poisoning.The fluoride accumulating ability in bone and tooth were stronger while the ability in blood,liver and kidney were weaker.
