  natural aberration rate
     The natural aberration rate was 2.18% and the average aberra- tion rate was 53.7% after RT(P<0.01). The relation between chromosomal aberration and the recent radiation effect was as follows.
     本组病人的自然畸变率为2.18%; 放射治疗后患者的平均畸变率为53.7%,明显高于自然畸变率(P<0.01)。

本文对60名80岁以上的老年人,进行外周血淋巴细胞分裂指数、染色体众数和自然畸变率的检查,并以22名健康中年人对照。结果指出:老年组外周血淋巴细胞的分裂指数较对照组显著下降,二倍体细胞减少,非整倍体增加,特别是亚二倍体细胞显著增加,染色体的自然畸变率也有显著差异。老年组男女间均无差异,由此看出人的衰老因素十分复杂,而外周血淋巴细胞的分裂指数,染色体众数和自然畸变率的改变,可作为研究衰老的微观指标之一。

The purpose of the present experimeats was to analyse the frequencies of meiotic non-disjunc tion and structural aberrations by comparative cytogenetic investigations in unfertilised oocytes (MH)and first-cleavage zygotes after pre-ovulatory treatment of female mice with cyclophos phamide ( CYC, 25, 50, 100mg/kg ) . CYC (100mg/kg ) induced meiotic non-disjunction, but no structural aberrations were detected at oocytes (MII ) .On the contrary, at first-cleavage zygotes, CYC revealed a strong clastogeaic effect,...

The purpose of the present experimeats was to analyse the frequencies of meiotic non-disjunc tion and structural aberrations by comparative cytogenetic investigations in unfertilised oocytes (MH)and first-cleavage zygotes after pre-ovulatory treatment of female mice with cyclophos phamide ( CYC, 25, 50, 100mg/kg ) . CYC (100mg/kg ) induced meiotic non-disjunction, but no structural aberrations were detected at oocytes (MII ) .On the contrary, at first-cleavage zygotes, CYC revealed a strong clastogeaic effect, as well as aneuploidy.The increase of frequencies of first-clearage zygotes with structural aberrations appeared to be correlated with the doses used.These results indicate that an intervening round of ,DNA replicatlon is necessary for a CYC induced DNA lesion to be transformed into a structural aberration.

采用超排卵技术使ICR雌性小鼠排卵,排卵前用环磷酰胺(CYC 25、50、100mg/kg)处理后与雄性小鼠交配,分析小鼠卵母细胞(MⅡ)及第一次分裂合子的染色体非整倍体及结构畸变。 对照小鼠MⅡ及第一次分裂合子均未发现有染色体非整倍体及结构畸变。环磷酰胺100mg/kg处理组小鼠MⅡ非整倍体率显著增加,但未见染色体结构畸变。 在小鼠第一次分裂合子中,环磷酰胺可使雌原核染色体非整倍体率增加,并诱发多种染色体结构畸变,畸变率随环磷酰胺剂量的增加而增加。该分析技术具有自然畸变率低、灵敏、快速等 优点。

The paper reports the chromosomal aberration of 80 cases with esophageal carcinoma treated for the first time with radiotherapy(RT). The natural aberration rate was 2.18% and the average aberra- tion rate was 53.7% after RT(P<0.01). The relation between chromosomal aberration and the recent radiation effect was as follows. Patients with high natural aberration rate before RT got poor effects, while those with lower rate got better results(P<0.05). The patients with higher rates of chromosomal aberration after RT got better results than those with lower rates (P<0.01). We believe that the results have an instructive significance for the study of the esophageal cancer's genesis and the evaluation of radiation effect during the treatment of esophageal carcinoma.

观察了80例首次进行治疗的食管癌患者放疗前后外周血中淋巴细胞染色体畸变情况。本组病人的自然畸变率为2.18%;放射治疗后患者的平均畸变率为53.7%,明显高于自然畸变率(P<0.01)。染色体畸变与近期放疗效果有如下关系:①患者自然畸变率高疗效差,反之疗效好(P<0.05)。②患者放疗后染色体畸变率高疗效好,反之疗效差(P<0.01)。该结果对食管癌的发病研究和食管癌放疗效果评价有指导意义。
