According to the PDR {Physicians Desk Reference} the toxic amount of Nembutal in the blood starts at 12 ppm and increases to the "Usual Death Level" of between 15 to 40 ppm. This means Marilyn had more Nembutal in her system than the scale even shows.

根据医师手册，血液中"戊巴比妥"含量超过12 ppm 就会引起中毒，15-40 ppm 就达到通常的致死浓度，这就说明玛丽莲·梦露体内的"戊巴比妥"的浓度已经超出了上述致死浓度。

The tolerance of seawater fish Japanese sea bass and black rockf ishto pH and alkalinity is studied through the experiment of acute toxicity. The median lethal concentration values are obtained by the method of probability unit. The safe concentrations of alkalinity, C032- and HC03- are obtained. The signification of pH and alkalinity is estimated with analysis of variance.

本文应用急性毒性试验方法研究了海水鱼类鲈鱼黑鲪对pH、碱度、二氧化碳体系各分量的耐受性，应用概率单位法求得半致死浓度，并得到了碱度、碳酸根、碳酸氢根等的安全浓度，应用方差分析评价了pH和碱度致毒作用的显著性，探讨了不同pH、碱度范围的主要致死因子。

Objective: To investigate the effect of lethal Vibrio vulnificus infection on the blood system and the pathology changes of the major organs in mice, and to explore the possible mechanism of the related death.

Polyhedrin and virion, which were isolated and purified from Agrotis setegum nuclear polyhedrosis virus, are administered to 3-instar Heliothis armigera larvae with Heliothis armigera nuclear polyhedrosis virus. Both polyhedrin and virion could increase mortality of H. armigera larvae, shorten half mortality time and decrease half mortality concentration.

对黄地老虎核型多角体病毒的多角体蛋白和病毒粒子组分进行分离纯化，分别与棉铃虫核型多角体病毒混合感染三龄棉铃虫幼虫，发现此二种组分均能够提高棉铃虫幼虫的死亡率，缩短半致死时间，降低半致死浓度。

Objective To investigate the protective effect of ligustrazine on brain injury.Methods The effects of ligustrazine on breath time of head decollated mice and survival time of hypoxic mice induced by sodium nitrite were observed and neurological score and infarct area in the middle cerebral artery occlusion rats were measured.

目的 研究川芎嗪对脑损伤的保护作用方法采用小鼠断头法、亚硝酸钠(NaNO2)致死法、鼠大脑中动脉栓塞法，通过观察断头喘息时间、亚硝酸钠致死时间、脑缺血行评分、脑缺血面积，明确川芎嗪对脑损伤的保护作用。

Trial of acute toxicity: The mouse were given once the drugs of The root (10g/ml)and leaf (9g/ml) of Panicled Fameflower by irrigating gastric in largest volume (0.3ml/10g).

急性毒性实验：土人参根、叶水煎液浓缩制成的最大浓度(土人参根10g／ml，土人参叶9g／ml)给予小鼠最大容积(0.3ml／10g)一次灌胃，若小鼠死亡，则测定半数致死量LD_(50；若毒性很小，测不出半数致死量：则改用一日内以小鼠能耐受的最大浓度和最大容积，灌胃3次；测定其最大给药量。

The lethal effects of ethyl formate on the eggs,early larvae,late larvae,pupae and adults of Tribolium castaneum were systematically studied under laboratory conditions with EtF fumigation with different dosages,treatment duration and temperature.

在不同的药剂浓度、处理时间和温度下系统研究甲酸乙酯对赤拟谷盗T.castaneum卵、低龄幼虫、高龄幼虫、蛹以及成虫的熏蒸致死作用，结果表明处理时间和温度显著影响甲酸乙酯对赤拟谷盗各虫态的熏蒸致死效果。

Even if you assume MS is mandatory, there are enough classes that have it now that you should be able to bring MS and a healer and have room for a Boomkin as your third.
