Objective To analyze the expression of skin proliferous cell nucleus antingen of patients with arseniasis caused by coal-burning.

摘要］ 目的分析燃煤型砷中毒患者皮肤增殖细胞核抗原的表达。

Human arseniasis is still the problem which has been paying close attention to so far in the internal and external medical field.

人类砷中毒至今仍是国内外医学界关注的课题。

MATERIALS AND METHODS: Using telomeric repeat amplification protocol assay and ABC immunohistochemical technique, the level of telomerase activation and PCNA expression were evaluated in 29 skin lesions of arseniasis patients and 10 cases of normal skin.

材料与方法：采用端粒重复序列扩增法和免疫组化ABC法检测29例砷中毒患者病损皮肤及10例正常皮肤组织中的端粒酶活性和PCNA表达情况。

Methods PCR-SSCP and PCR product cloning, sequencing were performed to detect mutation of p16 gene exon 2 in peripheral blood of 60 patients with arseniasis caused by coal-burning pollution,at the same time,PCR-based methylation assay was performed to analyze the methylation of p16 gene exon 1. Results No p16 gene exon 2 mutation was found in 60 cases.

采用聚合酶链反应-单链构象多态性分析和PCR产物克隆测序技术对60例砷中毒患者外周血中p16基因第2外显子突变情况进行检测，同时采用甲基化敏感的限制性内切酶方法对p16基因第1外显子甲基化情况进行分析。

Chronic arsenicism of the skin has been- documented to be extraordinarily high on the southwestern coast of Taiwan, especially in the endemic area of blackfoot diease.

台湾西部沿岸有较高的皮肤砷癌盛行率，其中以乌脚病地区最高。

In this paper, the distribution, type and geographically epidemic character of arsenism in China were reported.

Methods: Genetypes were determined by PCR RFLP approaches in 99 healthy controls and 92 patients with endemic arsenism.

本研究分析了新疆奎屯地区汉族人群中DNA修复基因XPDLys751Gln多态和地方性砷中毒发病风险的关系，现将结果报道如下。

Objective To understand the distribution of state of endemic arsenism in Jilin province.

目的 查清吉林省地方性砷中毒病区的病情情况。

Objective To clinically study the effect of Ginkgo leaf on hepatic damage resulting from coal- burning arsenism and its mechanism.

目的观察银杏叶片对燃煤型砷中毒慢性肝损害的临床疗效，并探讨其作用机制。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
