目的调查分析燃煤型氟中毒儿童与成人血锌含量的改变状况。方法随机选取本市燃煤型氟中毒患者50例和当地健康人群50例作为观察对象,以燃煤型氟中毒患者为研究组,以健康人群为对照组。给予两组进行空腹抽取静脉血,同时测定血锌的含量,此外,收集尿液及测尿氟的含量,然后组间比较差异。结果研究组中尿氟含量相对于对照组比较高(P<0.05),血锌含量相对于对照组比较低(P<0.05)。结论在燃煤型氟中毒的儿童及成人中,其体内的血锌含量出现降低的现象。
Objective To investigate the changes of blood zinc levels in children and adults with coal-based fluorosis. Methods Fifty cases of coal-burning fluorosis in our city and 50 cases of local healthy population were randomly selected as the observation object, the coal-burning fluorosis patients as the research group and the healthy population as the control group. The two groups were given fasting venous blood, meanwhile, the content of blood zinc was measured. In addition, urine and urinary fluoride contents were collected and compared among groups. Results The urinary fluoride content of the study group was higher than that of the control group (P <0.05), and the blood zinc level was lower than that of the control group (P <0.05). Conclusions In children and adults exposed to coal-based fluorosis, blood zinc levels in the body are reduced.
