| 2 | Family aggregation in a population of chronic arsenic poisoning associated with high arsenic coal burning显示文摘About 2600 cases of chronic arsenic poisoning (CAP) in Southwest China-Guizhou Povince represent a unique case of CAP in the world associated with indoor high As coal burning.An epidemiological investigation in 4 clans (694 subjects,male 299,female 395) was launched in one Cun(village) in JL area(21000 residents,about 2000 CAP cases).(1)Clan G(possible Hanized Yi origin).The ancestors,a couple settled here in Qing dynasty.CAP prevalence was 43.3%(93/215).It was found that in 9 of 25 brotherhood groups all the members suffered with CAP.(2) An non-consanguinous branch of family G.The ancestor,a boy was adopted by family G in 1890s.The incidence rate was 20.8%(11/53) which was lower than that in clan G(consanguineous)(P=0.00261,r=0.344),though both clans have been living in the same family for 4 generations.(3)Clan B(Han origin).The ancestor moved the family from Nanjing in Ming dynasty.The CAP prevalence is 45.5%(75/165).(4)Clan P(ethnic Miao).The CAP prevalence is 3.9(9/232),far less than other ethnic clans,for example,less than clan G (consanguineous)(P=3.706E=23,r=0.052944).The observation suggests possible family aggregation of CAP in high As coal using area.further work is required. | LinGF ChenJG | 2002 | 中国药理学与毒理学杂志2002，16，6： | 0 |
