去毒毒素

Pseudomonas cocovenenans subsp farinofermentans-bacterium responsible for some food poisoning, were first isolated from fermented corn in the North-east of China in 1977. The studies were conducted in our laboratory during the last decade on the antigen structure, identification methods for the bacterium by biochemical techniques and the characteristics of Bongkrekic acid, including structure, inducing machinism and curing method of the toxin.

椰毒假单胞菌酵米面亚种是我国学者于1977年在东北酵米面中毒食物中发现的一种新的食物中毒菌，我们曾对其菌体抗原结构，生化鉴定和检测方法以及其产生的毒素-米酵菌酸的结构、产毒机制和消毒、去毒等方面进行了深入的研究。

Researches on aflatoxin detoxification by traditional methods, as well as biological strategies are reviewed in this study.

文章对传统去毒方法和新型生物技术降解黄曲霉毒素的研究进行了综述。

This study has provided first molecular evidence that the mRNA expression of CYP1A was significantly induced in response to domoic acid. We suggest that phaseⅠxenobiotic metabolizing enzymes CYP1A, instead of phaseⅡxenobiotic metabolizing enzymes GST, might be major detoxified enzymes in the metabolism of amnesic shellfish poisoning toxin, domoic acid.

我们认为第Ⅰ时相去毒酶CYP1A是DA代谢的关键的酶，它可通过生物转化降低DA的毒性，而第Ⅱ时相去毒酶GST在DA代谢过程中的作用不显著，使毒素不能被有效地排出体外。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
