Research Abstract

1949年から1989年の間に,旧ソ連(現カザフスタン共和国)セミパラチンスク核実験場(SNT)において458同の核実験(地上30回,大気中88回,地下340回)が行われ、SNT地域住民に急性・慢性の放射能被爆をもたらし,高い頻度で造血系,循環器系,腫瘍性疾患等が発症している。
私たちは既に、SNT周辺の高線量被爆地域:HIR(1.0Sv以上)における唇顎口蓋裂発症率および口腔疾患罹患率は中等度被爆地域MIR(0.5-1.0Sv)や対照地域:CONと比較して有意に上昇していること、HIRの欠損歯数,口腔疾患罹患率,全身疾患罹患率はCONと比較して有意に上昇していることを明らかにした、また、核実験場周辺住民から採取した血液および唾液・歯垢由来のDNAを用いて、CONとHIRの成人で,因子A[IL-1α(889),IL-1β(-511)遺伝子多型]と因子B[地域差]を従属変数,喪失歯数(CON:10,37本,HIR:15.43本)を日的変数として,二元配置法による分散分析を行い,遺伝子多型により喪失歯数の違いがみられ(p<0.01)、地域差がより大きな喪失歯数への影響因子と考えられ,その因子として放射線の影響が最も強く疑われた。
