Both of the ESD were proportional to kVp 2.2 to kVp 2.5 and were linear proportion to mAs. Inverse square law exists in the relationship of focus-film distance, FFD, and ESD. The impacts of field size and patient thickness to ESD are negligible. Optimized operating condition is chosen to improve the diagnosis rate and to reduce the patient dose. The ESD, 0.12±0.06 mGy, performing the optimized operating condition of chest x-ray examinations, is less than both values of reference doses recommended by NRPB and IAEA.

研究结果发现，入射表面剂量随操作条件而变，以相同的条件照射，三相位X光机所造成表面剂量大约是单相位X光机的1.9倍；入射表面剂量与kVp的2.2至2.5次方成比例，与mAs约成线性正比，与焦斑至底片距离的关系大约符合平方反比定律；照野面积及身体厚度虽会影响表面剂量的大小，但其程度远低於kVp及mAs的影响。

Results Acute oral LD50 were 278 mg/kg and 56.2 mg/kg in rats and mice respectively, while dermal LD50＞2 000 mg/kg and inhalative LC50＞3 000 mg/m3. Skin and eye irritancy were estimated to be negative and mild respectively. Cumulative coefficient was 2.3 and allergic rate was 0%. A negative result was observed in Ames assay while increased frequencies of bone marrow micronuclei and spermatocyte chromosome aberrations were noted in the high dose (11.24 mg/kg) group.

结果 大小鼠急性LD50分别为278 mg/kg和56.2 mg/kg；大鼠经皮LD50＞2 000 mg/kg；急性吸入LC50＞3 000 mg/m3；无皮肤刺激性，轻度眼刺激性；蓄积系数2.3；致敏率为0；Ames试验结果阴性；微核和染色体在高剂量组(11.24 mg/kg)与阴性对照组相比有高度显著性差异(P＜0.01)；大鼠90天亚慢性经口的最大无作用剂量为2.825 mg/kg。

The results showed that mercury chloride (0.5 and 1.5mg/kg BW) had obviously toxicity to the liver and the kidney of mouse, and the dose of 1.5mg/kg BW could damage the ovary function and reduce the number of superovulation oocytes.The results also showed that mercury chloride could inhibit the extruding of the first polar body and affect the quality and the viability of mouse oocyte and reduce the rate of IVF,but little impact on germinal vesicle breakdown of mouse oocyte in vivo.

结果表明，0.5和1.5mg/kg BW汞对小鼠的肝脏、肾脏有明显的毒性作用，1.5mg/kg BW组还对卵巢有明显的毒性作用，并能显著降低超排卵的卵母细胞数；汞对体内卵母细胞生发泡破裂没有影响，但可以抑制卵母细胞第一极体的释放，影响卵母细胞的存活率并降低体外受精率。

MeV ions result in high damage rate, and the relation between remained sample and dose almost consistents with the target model.

MeV离子导致了高的损伤速率，残存率和离子剂量之间的关系也基本符合靶模型的预期。

Statistical analysis was done for the rate of bone marrow cell micronucleus induced by different dose of formaldehyde.

KM strain mice immunosuppressed with 7. 5～10mg/L DEX in drinking water had the higher oocysts output and fewer dead than other groups.(4) There was no significant difference infection rate between groups inoculated with different number CSO and groups inoculated CSO with conserved different time. Trial were divided into control, groups of 50mg/kg /d, 100 mg/kg /d and 200 mg/kg /d dose of the drug to study the anticryptosporidial activities of nitazoxanide in an immunosuppressed mice model. The experimental results showed the treatment with 200mg/kg bw /day was significant inhibition of oocyst excretion. To detect the two cryptosporidiums strain C.

实验结果表明：C.parvum虫种能够感染上本实验所采用的BALB／c和昆明小白鼠两种小鼠，而C.andersoni没有能够感染本次实验小鼠；且从小鼠感染后的排卵囊量和小鼠的生存状态来看，采用5～6周龄的KM鼠能获得最大量的隐孢子虫卵囊，小鼠的死亡数最少；每升饮水中地塞米松量为7.5mg～10mg组比12.5mg以上组小鼠死亡数量少，比5mg／L以下组排卵囊数量多；接种不同卵囊数和卵囊的保存时间这两个参数均对小鼠受感染后的排卵囊情况影响不大。
