Sialidase activity identical to 0.0196 mg per ml of liberated sialic acids (2.11 Units) was detected in small intestinal contents of goats. Mg++ and Ca++ induced in vitro detection in mucosa cells of both small and large intestines. Magnesium alone induced sialidase activities identical to 0.0128 mg per ml of liberated sialic acids (1.38 Units) and 0.0166 mg per ml (1.79 Units) in small and large intestinal mucosal cells, respectively. Mg++ and Ca++ together induced higher sialidase activities identical to 0.0191 mg per ml (2.06 Units) and 0.0194 mg per ml (2.09 Units) in small and large intestinal mucosal cells, respectively. The enzyme activity was slightly higher in large than in small intestinal mucosal cells. The results are discussed in relation to control of African animal trypanosomiasis.
在山羊小肠内容物中检测到唾液酸酶活性,相当于每毫升释放的唾液酸0.0196毫克(2.11单位)。镁离子(Mg++)和钙离子(Ca++)在体外可诱导小肠和大肠黏膜细胞中的检测。单独的镁离子在小肠和大肠黏膜细胞中分别诱导出相当于每毫升释放的唾液酸0.0128毫克(1.38单位)和0.0166毫克(1.79单位)的唾液酸酶活性。镁离子和钙离子共同诱导小肠和大肠黏膜细胞中更高的唾液酸酶活性,分别相当于每毫升0.0191毫克(2.06单位)和0.0194毫克(2.09单位)。酶活性在大肠黏膜细胞中略高于小肠黏膜细胞。结合非洲动物锥虫病的控制对结果进行了讨论。
