The research of degree of incidence of genomic changes (of micronuclei) in mucous cells of gastric superficial-foveolar epithelium in contaminated and not contaminated mucous of stomach was made. Histopathological research of micronuclei and helicobacter was made in gastric biopsy specimen of patients with diagnosis-chronical gastritis (ICD-10K29.3) in group of patients who lived in radiation contaminated areas and in groups of people, who had no factors of radiation influence in anamnesis. people, who lived in the radiation contaminated areas, whose mucous was infected by Helicobacter pylori, had the highest frequency of mucous cells with micronuclei. In the group of patients from radiation contaminated areas with Hp-associated gastritis frequency of appearance of mucous cells with micronucleus in the mucous of stomach have five time more, than patients, whose mucous of stomach was not infected (p Helicobacter pylori can success in mutagenic effect of radiation factor.

为了研究切尔诺贝利事故清理工作者和其他受照射人员外周血淋巴细胞,选取切尔诺贝利事故清理工作者和其他受照射人员作为试验组,采用常规方法取指尖外周血制备涂片,空气干燥,对氨基苯甲酸混合,Giemsa法染色,光镜下计数每人500个细胞样本,观察记录具有尾状突起细胞核发生率,进行统计学处理。未照射对照组的外周血淋巴细胞尾核发生率在0%～0.6%,平均值0.16。而大多数受照射对象都出现较多具有尾核的淋巴细胞。照射组的淋巴细胞出现尾核最大值是3.2%,平均值是0.50%。切尔诺贝利事故清理工作者的带尾核的淋巴细胞出现的几率显著高于对照组(p<0.01)。外周血淋巴细胞尾核可能是一种有意义的受照射标记物,受照射淋巴细胞尾核的异常出现可能起因于双着丝粒所形成的染色体桥的断裂。对于更加详尽地获取辐射生物效应信息,回顾性研究辐射剂量效应可能具有重要的理论和实践价值。
