通过对近年来广西近岸海域贝类样品的麻痹性贝毒素小白鼠生物法和高效液相色谱法检测结果的分析，表明广西近岸海域多处地区和多种生物含有麻痹性贝毒素；4-5 月及7-11月为两个毒性值的年高峰期；GTX4、GTX5和GTX3毒素成分的检出率较高等。

The Culture of Green beaus in extract solution of seven poisonous mushrooms resulted in different effects. There are obvious difference among the content of the proteins in Green beaus which were cultured in extract solution of seven poisonous mushrooms, and it is thought that α-amanitin in extract solution of these mushrooms can inhibit the function of RNA polymerase Ⅱ in eukaryoctic cells and further inhibit the synthsis of protein.

用鹅膏菌属含α-毒伞肽的毒素粗提液培养新鲜绿豆，结果在36小时后，各种不同毒苗的毒素粗提液培养的绿豆生长情况有明显不同，用紫外吸收法测定蛋白质含量，发现毒素粗提液培养的绿豆细胞中蛋白质含量比蒸馏水培养的有明显下降，这表明α-毒伞肽的作用机理的确是通过抑制RNA聚合酶Ⅱ而寻致蛋白质合成减少。

Chenopodium serotinum is the most susceptive, and D. sanguinalis, Polygonum aviculare, Beckmannia syzigachna, Chenopodium album and Alopecurus japonicus took second place.

该毒素在150μg/mL浓度下，对马唐胚根生长抑制率达44.59%；当毒素浓度达到200μg/mL时，叶绿素含量下降18.41%；在500μg/mL浓度下，毒素对供试的23种杂草产生的毒害程度不同，其中小藜对毒素最为敏感，其次为马唐、萹蓄、菵草、藜和日本看麦娘等恶性杂草。

The effect of Coriaria lactone on amino acid nerve transmission substance: Coriaria lactone is a kind of nerve toxicant can made amino acid nerve transmission substance content of insect change and the content of GABA increase obviously, the content of Glu change little or decrease slightly.

马桑毒素对昆虫氨基酸神经递质的影响：马桑毒素是一种神经毒剂，作用于昆虫引起体内的氨基酸神经递质含量发生变化，其中GABA含量明显升高，GLU含量变化不大稍有下降，并且马桑毒素侵入虫体后，试虫具有兴奋-吐出中肠液-瘫软-昏迷-死亡的症状，表明马桑毒素是试虫的神经传导中GABA的特殊拮抗剂。

Armigera and M. separata mid-gut juice, but, other less than 60kD proteins also can be got by M. separata mid-gut juice .4 Many Bt Cry1AcE toxins can be got by the method of precipitate and resolve, which have high purity.

在相同的时间下，粘虫中肠消化液蛋白酶活性比棉铃虫中肠消化液要高；在37℃条件下，棉铃虫中肠消化液经过30和60min将130kD的Bt CrylAc原毒素酶解为60kD的毒素，而粘虫中肠消化液经过30和60min对Bt CrylAc原毒素酶解作用，除得到60kD的毒素外还得到了40kD和分子量更小的蛋白。

Of particular interest are toxic or biologically disruptive impacts of anthropogenic chemicals such as pharmaceuticals, industrial organics, agricultural chemicals, and by-products such as chlorinated compounds from water disinfection and waste incineration; natural toxins and their impacts biotransformation and metabolism of toxigenic compounds, food chains for toxin accumulation or biodegradation; assays of toxicity, endocrine disruption, mutagenicity, carcinogenicity, ecosystem impact and health hazard; environmental and public health risk assessment, environmental guidelines, environmental policy for toxicants.
