Fate of metallic mercury in the body.

为了了解过氧化氢酶对物质汞暴露小鼠体内分布和排泄的影响，进行了以下实验。1 .金属汞暴露的非致凝血小鼠(A)动脉血中金属汞浓度高于正常小鼠(N)，但动脉血中汞离子浓度反之。暴露于金属汞的小鼠呼出的汞量与暴露于金属汞的小鼠的汞浓度成正比。A组和N组小鼠分别注射乙醇(E)或氨基三唑（AT），然后接触金属汞。小鼠呼出的汞量依次为A- at >N- at >A- et >N- et >A>N。N- et组肾汞浓度和尿汞浓度均高于N- et组。暴露于金属汞的孕鼠胎儿汞浓度与血汞浓度之比依次为A- at >N- at >A>N。

In order to know the effect of catalase on the distribution and excretion of the mice exposed to matellic mercury, following experiments were performed.1. Concentration of metallic mercury in an arterial blood of acatalasemic mice (A) exposed to metallic mercury was higher then that of normal (N), but concentration of mercuric ion in the arterial blood was vice vera.2. Amounts of mercury exhaled from mice exposed to metallic mercury were in proportional with mercury concentration exposed mice.3. Both mice of A and N were injected with ethanol (E) or aminotriazole (AT) followed by being exposed to metallic mercury. The amount of mercury exhaled from mice is descending order of A-AT>N-AT>A-ET>N-ET>A>N. Concentration of mercury in kidneys and urine of N-ET was higher than that in N, respectively.4. The ratio of mercury concentration in fetus to that in blood of pregnant mice exposed to metallic mercury was in the descending order of A-AT>N-AT>A>N.
