ResultsESC(the extract of Solidago canadensis L.) markedly prolonged the writhing latent period and decreased the times of writhing of mice induced by ip acetic acid, while it had no obvious effect on the pain threshold value in hot plate test. ESC significantly prolonged the tussive latent period of mice, decreased the tussive times and increased phenolsulfonphthalein excretion quantity of trachea of mice. ESC was nontoxic according to the acute toxicity test.

结果首次对国产加拿大一枝黄花进行了体内药理作用研究，发现加拿大一枝黄花提取物能显著延长醋酸致小鼠扭体潜伏期，减少扭体次数；但未明显提高热板法实验小鼠的痛阈值；能显著抑制浓氨水所致小鼠咳嗽潜伏期和咳嗽次数；显著增加小鼠气管的酚红排泌量；急性毒性实验表明加拿大一枝黄花提取物无明显毒性，既不引起小鼠死亡也不影响小鼠体重正常增加。

在不降低DDP和TAX疗效的情况下，YR-1对化疗药物所致荷瘤动物免疫功能的降低和骨髓抑制具有明显的拮抗作用，提示YR-1对化疗所致的免疫功能损伤和骨髓损伤具有保护作用。

The experimental results show that the distributions of content and toxicity equivalent quantity of PAHs in raw coal are similar to coal gasification but this compositions and contents are different. The rise of coal rank leads to the decrease of the content and TEQ of PAHs in raw coal and the increase of TEQ during coal gasification, while the content of PAHs emission from coal gasification increases first and then decreases with the increase of coal rank. The total PAHs contents generated in coal gasification of some sorts of coals are higher than in raw coal. The types of PAHs formed in coal gasification include undecomposed PAHs in raw coal, pyrosysthensis PAHs, and radical polymerization PAHs at high temperature.

试验结果表明：煤气化前后多环芳烃质量分数和毒性当量质量分数的分布特徵相似，但多环芳烃的组成和质量分数不同；煤化程度增加，原煤多环芳烃质量分数和毒性当量质量分数减小，煤气化多环芳烃质量分数先增后减，毒性当量质量分数与煤化程度呈线性关系；部分煤种气化多环芳烃的质量分数高於原煤多环芳烃质量分数，且煤气化多环芳烃的种类分为原煤未分解的多环芳烃、热解合成的多环芳烃、自由基高温缩合生成的多环芳烃。
