Abrin is one of the potent toxins isolated from the beans of plant abrus precatorius.the toxic protein consists of two disulfide-bonded subunits,the a and b chains.the b chain is a galactose-specific lectin that facilitates the binding of abrin to the cell membrane that precedes endocytosis.after entering the cells,the a chain catalytically inactivates 60s ribosomal subunits by removing adenine position 4324 of 28s r–rna,and thereby inhibits protein biosynthesis.

相思子毒素是从豆科植物(abrus precatorius l。)种子中分离的一种细胞毒性蛋白。它由a，b两条链组成，由一个二硫键相联，b链具有半乳糖凝集活性，可与细胞膜上受体结合，帮助a链进入细胞内，a链进入细胞催化失活60s核糖体亚基，从而使细胞蛋白合成被抑制。

By careful examination of these specimens both morphologically and histologically, three different species were identified, namely:(1)Abrus cantonien...

Will give you a red bean, so bright, such as blood, Abrus precatorius blessing echoed in the wind, clear sky, Acacia into the beans.

鸡骨草Abrus cantoniensis Hance，又名广州相思子、细叶鸡骨草、小叶鸡骨草，为豆科相思子属植物［1］，原产广西、广东等南部省区，以广西的栽培面积最大，是广西的道地药材，其植株含相思子碱、皂苷、黄酮苷、胆碱、甾醇类、氨基酸、糖类化合物等化学成分［2］，药用部位为去除荚果后的干燥全草，具有清热解毒、疏肝止痛之功效，用于治疗黄疸、胁肋不舒、胃脘胀痛、急慢性肝炎等疾病［3］。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
