成年绿头鸭(Anas platyrhynchos)被喂食了含有10 ppm和10 ppm的饮食... 当饮食中除了10 ppm外还含有10 ppm时,12只雄性鸭子中没有一只生病。与对雄性中毒的保护作用相比,对繁殖成功的一些测量指标来说比单独使用更糟糕。都通过降低孵化成功率和鸭苗存活率来减少鸭苗的产生,但的组合比单独使用更糟糕。对照组每只雌性平均产生7.6只幼崽... 而同时喂食的雌性只产生了0.2只幼崽。对于的联合处理,致畸作用也更糟;对照组的胚胎中记录到6.1%的畸形,喂食甲基汞化物的胚胎中为16.4%,喂食代甲酸的为36.2%,喂食甲基汞化物和代甲酸的为73.4%。饮食中甲基汞的存在大大增强了组织中的储存。喂食10 ppm的雄性鸭子的肝脏平均含有9.6 ppm,而喂食10 ppm加10 ppm的雄性鸭子的肝脏平均含有114 ppm。然而,并没有增强的储存。结果表明,对成体可能是相互拮抗的,而对幼体可能是协同的,即使在同一实验中也是如此。
Adult mallards (Anas platyrhynchos) were fed ... a diet 10 ppm mercury plus 10 ppm selenium. ... When the diet contained 10 ppm selenium in addition to the 10 ppm mercury, none of 12 males became sick. In contrast to the protective effect of selenium against mercury poisoning in males, selenium plus mercury was worse than selenium or mercury alone for some measurements of reproductive success. Both selenium and mercury lowered duckling production through reductions in hatching success and survival of ducklings, but the combination of mercury plus selenium was worse than either mercury or selenium alone. Controls produced an average of 7.6 young per female ... and females fed both mercury and selenium produced 0.2 young. Teratogenic effects also were worse for the combined mercury plus selenium treatment; deformities were recorded in 6.1% of the embryos of controls, 16.4% for those fed methylmercury chloride, 36.2% for those fed selenomethionine, and 73.4% for those fed methylmercury chloride and selenomethionine. The presence of methylmercury in the diet greatly enhanced the storage of selenium in tissues. The livers of males fed 10 ppm selenium contained a mean of 9.6 ppm selenium, whereas the livers of males fed 10 ppm selenium plus 10 ppm mercury contained a mean of 114 ppm selenium. However, selenium did not enhance the storage of mercury. The results show that mercury and selenium may be antagonistic to each other for adults and synergistic to young, even within the same experiment.

每10只雄性ICR小鼠一组,被给予含有40毫克/克饲料的氯化甲基汞,以及饮用中含有或不含有20毫克/毫升的褪黑素,持续5周。单独接受氯化甲基汞处理的小鼠表现出神经毒性的迹象(异常翻正反射、蹒跚步态、倒伏姿势)的数量更多,并且在治疗35天后的死亡率高于同时接受氯化甲基汞褪黑素处理的小组。这表明褪黑素的抗氧化能力可以减少氯化甲基汞的毒性......
Groups of 10 /male ICR/ mice were given methylmercury chloride at a concentration of 40 mg/g of diet, with or without melatonin at a concentration of 20 mg/mL in drinking-water, for 5 weeks. Greater numbers of animals treated with methylmercury alone showed signs of neurotoxicity (abnormal righting reflex, staggering gait, fallen posture) and a higher rate of mortality after 35 days of treatment than the group receiving methylmercury plus melatonin. It was suggested that the anti-oxidative capacity of melatonin reduces the toxicity of methylmercury ...

组织化学定位(通过增强放大)显示的分布不同。在大鼠饮用含有16毫克/升甲基汞化物的后10天,首次在大脑中发现了的沉积。这些沉积最初出现在脑干,然后是大脑皮层和视上核,最后是小脑和丘脑。20天后,小脑皮层的沉积仅限于普尔杰细胞和戈尔吉上皮细胞,而脊髓中的沉积则限于前运动神经元;小脑皮层的颗粒细胞未发生染色...在每天腹膜内注射0.16-0.8毫克/千克体重的甲基汞化物后,也看到了类似的染色...由于小脑颗粒细胞是甲基汞的靶细胞...,缺乏染色表明只有去甲基化的可以通过增强放大方法检测到。当使用相同的方法对猕猴的枕叶沟皮层进行染色时,六个月后在天胶质细胞和小胶质细胞中看到了大量的沉积,而神经元的染色出现得更晚,即使在18个月后仍然很浅...在给予每周剂量的(3)H-甲基汞的松鼠猴中,蛋白质中的含量增加,并且发现在受损但未在未受损的神经元中。
Histochemical localization (by silver amplification) of mercury showed a different distribution. The first deposits of mercury in rat brain became apparent 10 days after exposure to 16 mg/L of methylmercury chloride in drinking-water. The deposits were found initially in the brain stem, then in the cerebral cortex and supraoptic nucleus, and finally in the cerebellum and thalamus. After 20 days, the deposits in the cerebellar cortex were restricted to Purkinje cells and Golgi epithelial cells and those in the spinal cord to the anterior motor neurons; the granule cells of the cerebellar cortex remained unstained ... Similar staining was seen after daily intraperitoneal administration of methylmercury chloride at 0.16-0.8 mg/kg bw ... As the cerebellar granule cells are target cells for methylmercury ..., the absence of staining indicates that only demethylated mercury can be detected with the silver amplification method. When the cortex of the calcarine sulcus of macaque monkeys was stained by the same method, large deposits were seen in the astrocytes and microglia after six months, whereas staining of neurons appeared later and remained faint even after 18 months ... In squirrel monkeys given weekly doses of (3)H-methylmercury, the amount in protein increased, and it was found in damaged but not in undamaged neurons.

除了大鼠之外,所有测试物种的脑血比都大于1……在猴子中,这个比率始终很高,在所有物种中,多次给药后的比率高于单次给药后的比率。品系和性别的差异对小鼠血液中的浓度影响大于对大脑中的浓度影响。在大脑中,雌性小鼠的浓度高于雄性小鼠。在大鼠中,也观察到了大脑浓度的性别差异,但大脑与血液的比例没有差异。在连续四天口服剂量为8 mg/kg bw的甲基汞化物后6到12天,雌性大鼠大脑中的浓度为8.8 ug/g,雄性大鼠为6.7 ug/g……在重度暴露的长臂猿中,脑干的浓度与小脑和大脑的大部分区域相似,除了枕叶,枕叶的浓度最高……丘脑的浓度略高于枕极……在猪中,大脑、小脑和视神经的浓度差异很小,且都高于脊髓……在豚鼠中,小脑的浓度最低……在大鼠中,最高的浓度发现于脊髓根和神经节,其次是大脑皮层和小脑……,但是小脑、延髓和大脑不同区域的浓度差异很小。
Except in rats, the brain:blood ratios were greater than 1 in all species tested ... The ratio was consistently high in monkeys, and in all species it was higher after multiple dosing than after the administration of a single dose. Differences in strain and sex affected the concentration of mercury in blood of mice more than that in brain. The concentration in the brain was higher in female than in male mice. A similar sex difference in brain mercury concentrations, but without a difference in the brain:blood ratio, was seen in rats. Six to 12 days after four daily oral doses of methylmercury chloride at 8 mg/kg bw, the concentration of mercury in brain was 8.8 ug/g in female and 6.7 ug/g in male rats ... In heavily exposed squirrel monkeys, the brain stem had approximately the same concentration as the cerebellum and most of the cerebral regions, with the exception of the occipital lobe, which had the highest concentration ... The thalamus had somewhat higher concentrations than the occipital pole ... In pigs, the concentrations in the cerebrum, cerebellum, and optic nerve differed only slightly, and all had higher concentrations than the spinal cord ... In guinea-pigs, the cerebellum had the lowest concentration ... In rats, the highest concentration was found in the spinal roots and ganglia, closely followed by the cerebral cortex and the cerebellum ..., but the concentrations in the cerebellum, medulla oblongata, and various areas of the cerebrum differed only slightly.

被圈养的大贼鸥(Catharacta skua)血液和羽毛中的动态在56周内进行了监测。在换羽开始之前,的摄入仅来自它们维持生命所需的小沙丁鱼(Sprattus sprattus)配给。在换羽的前半段,除了从沙丁鱼中摄入之外,鸟类在20周内每周都会被喂食不同剂量的甲基氯。在换羽的后半段,停止给药,的摄入仅来自沙丁鱼。整个研究过程中采集了血液样本,并监测了羽毛的生长。在换羽开始之前,浓度在前51到71天内增加,此后似乎趋于平稳。基于哺乳动物药代动力学的重复给药模型通常过于简单,无法适用于本研究中的鸟类。在换羽期间,血液中的消除最好用三室模型来描述。羽毛中的浓度与它们生长时的血液中的浓度显著相关,这表明血液和羽毛反映了同一时间段内的摄入。个体在将摄入的排泄到羽毛中的能力上有所不同。
Mercury dynamics in the blood and feathers of captive great skuas, Catharacta skua, were monitored over 56 weeks. Prior to the onset of molt, mercury intake was solely from their maintenance ration of sprats, Sprattus sprattus. For the first half of molt, in addition to mercury intake from sprats, birds were fed different doses of methylmercuric chloride weekly for 20 weeks. During the second half of molt, dosing was stopped and mercury intake was solely from sprats. Blood was sampled throughout the study and feather growth was monitored. Prior to the onset of molt, mercury concentrations increased over the first 51 to 71 days and appeared to level off after this period. Repeated dosing models based on mammalian pharmacokinetics were, in general, too simplistic to be applicable to the birds in the study. During molt, the elimination of mercury from the blood is probably best described by a three-compartment model. Mercury concentrations in feathers were significantly correlated with those in blood at the time of their growth, suggesting that blood and feathers reflect mercury intake over the same time period. Individuals varied in their ability to excrete ingested mercury into the feathers.

    Reactions of alkylgold(I) complexes [AuRL](R = Me, L = PMe3, PMe2Ph, or PMePh2; R = Et, L = PMePh2) with hexafluorobut-2-yne give first the mixed-oxidation-state complexes [LAu(F3C)CC(CF3)}AuR2L], which react further to give either the binuclear gold(I) complexes [LAu(F3C)CC(CF3)}AuL] or the products of cis in-sertion of the alkyne into the original Au–C bond, [AuL(F3C) CCR (CF3)}]. The course of
    烷基(I)配合物[AuRL](R = Me,L = PMe 3,PMe 2 Ph或PMePh 2 ; R = Et,L = PMePh 2)与六丁-2-炔的反应首先产生混合氧化-态络合物[LAu (F 3 C)C C(CF 3)} AuR 2 L],它们进一步反应生成双核(I)络合物[LAu (F 3 C)CC C(CF 3)} ] AUL或产物顺在-插入可以炔成原始的Au-C键,[AUL (F的3 ç)C CR(CF 3)}]。此后续反应的过程取决于L和R的性质以及溶剂,并且已经研究了反应机理。氯化氢与[LAu (F 3 C)CC C(CF 3)} AuMe 2 L](L = PMe 3)反应,裂解乙烯基(I)键,得到[AuCIL]和[AuMe 2 L (F 3 C)ç CH(CF 3)}],而属卤化物的HgCl 2,[PTX 2(PMePh 2)2 ]}最初反应以

    phenylselenolate mercury alkyl compounds, PhSeHgMe and PhSeHgEt, have been structurally characterized by X-ray diffraction, thereby demonstrating that both compounds are monomeric with approximately linear coordination geometries; the mercury centers do, nevertheless, exhibit secondary Hg***Se intermolecular interactions that serve to increase the coordination number in the solid state. The ethyl derivative, PhSeHgEt
    硒酸烷基化合物PhSeHgMe和PhSeHgEt在结构上已通过X射线衍射进行了表征,从而证明这两种化合物都是具有近似线性配位几何结构的单体。但是,中心确实表现出二次Hg *** Se分子间相互作用,从而增加了固态的配位数。乙基衍生物PhSeHgEt在室温下容易进行Hg-C键的蛋白解裂解,释放出乙烷,而PhSeHgMe在相似条件下几乎没有反应性。有趣的是,PhSeHgEt的Hg-C键的裂解也比硫醇盐类似物PhSHgEt的裂解更容易,这表明的配位促进了-碳键的蛋白解。苯硒酸酯化合物PhSeHgR(R = Me,Et)也与例如PhSHgR和RHgCl进行简并的交换反应。在每种情况下,烷基均保持与199Hg核的偶联,从而表明交换过程涉及Hg-SePh / Hg-X基团的复分解,而不是Hg-R / Hg-R基团的复分解。

Herein, it is reported that the N,N‐disubstituted benzimidazole‐based thione 1 containing a N−CH2CH2OH substituent converts MeHgCys and MeHgSG complexes to less toxic water‐soluble HgS nanoparticles (NPs) and releases the corresponding free thiols CysH and GSH from MeHgCys and MeHgSG, respectively, in solution by unusual ligand‐exchange reactions in phosphate
    甲基汞(MeHg +)等有机物是对人类最具毒性的物质。除了抑制蛋白质外,MeHg +还通过与内源性巯基半胱酸(CysH)和谷胱甘肽(GSH)牢固结合形成MeHgCys和MeHgSG复合物,发挥细胞毒性作用。在此,据报道含有N-CH 2 CH 2的N,N-二取代的苯并咪唑酮1OH取代基将MeHgCys和MeHgSG复合物转化为毒性较小的溶性HgS纳米颗粒(NPs),并通过在37°C下在磷酸盐缓冲液中进行不寻常的配体交换反应,分别从MeHgCys和MeHgSG中释放出相应的游离醇CysH和GSH。但是,尽管含有N-CH 2 CH 2 OH取代基,但相应的N-取代的苯并咪唑酮7和N,N-二取代的咪唑酮3未能转化MeHgX(X = Cys和SG)到相同的反应条件下的HgS的NP,这表明不仅N-CH 2 CH 2 OH基团,但在苯并咪唑环和N,N-二取代1导致在1:1 MeHg共轭
