He activity of y-GT also had dose- dependent and time-dependent effect and became lowest on day 7 at the concentration of 0.5 and 1.0 umol/L. The activity of TAT increased. On day 4, the cells treated with 0.25, 0.5 and 1.0 umol/L of As2O3 had higher activity compared with control group (P.05) and it continued afterwhile.

AT随着各给药组时间的延长而上升，并随给药剂量增大而上升程度更大，培养第4天，0.25 μmol／L浓度的亚砷酸组TAT的比活性较对照组高(P＜0.05)，0.5 μmol／L、1 μmol／L浓度的亚砷酸组TAT的比活性较对照组更高(P＜0.01)，以后各天给药组均高于对照组(P＜0.01)。

objective to observe the effect of unithiol for the treatment of arsenic apicitis.methods sixty-three patients received therapy with 5% unithiol and the therapeutic effect was retrospectively analyzed.results 59 of 63 teeth were cured with the cure rate 92%; no effect was observed in 4 cases.conclusion unithiol can be effectively used for the treatment of arsenic apicitis.

目的 观察二巯基丙磺酸钠治疗砷性根尖炎的疗效。方法 63例患者患牙63颗接受5%二巯基丙磺酸钠治疗，回顾分析其疗效。结果 63颗患牙经本药治疗后59颗显效，占93.7%；4颗无效。结论二巯基丙磺酸钠可有效并安全用于治疗砷性根尖炎。

P53mt gene play a certain role in the development of skin cancer from arseniasis caused by coal-burning; the detection of P53mt protein can show whether pathological changes of skin due to the disease is malignant or benign.

结论燃煤型砷中毒致皮肤癌变过程中，P53mt基因起一定作用。P53mt蛋白的检测可用于燃煤型砷中毒病变皮肤的良、恶性鉴别。

Methods 0, 2.5, 5, 10, 15 and 20 μmol/L arsenious acid-treated human hepatocellular carcinoma HepG2 cells were cultured under hypoxia for 8 hours.
