【瘦肉精的危害】
“瘦肉精”进入动物体内后主要分布于肝脏。肌肉中含量较肝脏低很多。人摄入后在体内存留时间较长,其不良反应主要有:可引起心率加速,特别是原有心律失常的病例更易发生心脏反应,可见心室早搏、ST段与T波幅压低,还会发出肌肉震颤,引发四肢、面颈部骨骼肌震颤,尤其是交感神经功能亢进的病例更易发生。此外,还可引起代谢紊乱、血钾降低,引起心慌、肌肉震颤、头痛以及脸部潮红等。对心率失常、高血压、青光眼、糖尿病、甲状腺机能亢进等疾病的患者有较大危害。

三、分子生物学诊断方法
随着生物科学技术的快速发展,一些分子水平上的检测方法在毒素检测上得到了普遍应用。Kadra等为了验证PCR的准确可靠性,用PCR方法对不同来源的产气荚膜梭菌及毒素进行分型验证,将90株产气荚膜梭菌用细菌生化试验等方法进行验证,然后用小鼠血清中和试验进行定型,再用PCR法扩增α、β和ε三种毒素基因片段,zui后将两种定型方法鉴定的血清型进行验证,结果表明,两种方法定型*。表明PCR法准确可靠,且比小鼠的血清中和试验节约成本,方便可靠。于晓霞等为了寻找一种快速、准确的方法检测产气荚膜梭菌毒素型,采用SDS-PAGE的方法,对不同的产气荚膜梭菌分离株所产的外毒素蛋白进行分子量测定,从而确定所产外毒素的种类,确定菌株型。Fach等首先研究了用聚合酶链反应(PCR)方法检测毒素,参考毒素其他杆菌的磷脂酶C基因,设计了保守区域的针对基因特异性的引物,用PCR法扩增除了基因片段与毒素基因内的序列**,表明可以使用PCR方法检测毒素基因,从而验证细菌型。Warren等应用PCR方法对包埋在福尔马林里的含有产气荚膜梭菌的病料进行基因检测,扩增到了α、β和ε毒素基因,虽然产气荚膜梭菌已经死亡,但产气荚膜梭菌基因依然没有被破坏,因而PCR方法可以检测死亡产气荚膜梭菌的存在。
拟杆菌属(Bacteroides)又称类杆菌属,是拟杆菌科的一属,为革兰氏染色阴性、无芽孢、专性厌氧的小杆菌。
拟杆菌属正常寄居于人和动物的肠道、口腔、上呼吸道和违禁品道。人们zui初对拟杆菌的认识就是由它的致病性引起的。随着时间的推移和研究的深入,尤其是微生态学的发展,人们逐渐认识到拟杆菌是人和动物体内大量存在的正常菌群,约占成年个体肠道菌群的1/4以上。拟杆菌和其它菌群以及宿主之间有着复杂而微妙的关系,对宿主的健康起着重要的作用。同时拟杆菌也是条件致病菌,当其正常的微生态平衡被打破时,可引发内源提共染。因此可以说拟杆菌犹如一把违禁品剑.一方面具有益生机制,另一方面又具有致病机制。
拟杆菌属中比较重要的是脆弱拟杆菌和产黑色素拟杆菌。

Third, molecular biology diagnostic methods
With the rapid development of biological science and technology, some molecular level detection methods have been widely used in the detection of toxins. Kadra et al. In order to verify the accuracy and reliability of PCR, the Clostridium perfringens and toxin from different sources were identified by PCR. 90 strains of Clostridium perfringens were confirmed by the method of bacterial biochemistry, The mouse serum neutralization test was performed. The three α, β and ε toxin gene fragments were amplified by PCR. Finally, the serotypes identified by the two typing methods were validated. The results showed that the two methods were consistent. PCR method is accurate and reliable, and cost-saving than the mouse serum neutralization test, convenient and reliable. Yu Xiaoxia and so in order to find a rapid and accurate method for the detection of Clostridium perfringens toxin type, using SDS-PAGE method, different Clostridium perfringens isolates of exotoxin protein molecular weight determination , To determine the type of exotoxin produced, to determine the strain type. Fach et al first studied the use of polymerase chain reaction (PCR) detection of toxins, with reference to other phospholipase C toxins gene, designed a conserved region of the gene-specific primers, amplified by PCR in addition to gene fragments and toxins gene The exact sequence within the sequence indicates that the toxin gene can be detected using the PCR method to verify the bacterial species. Warren et al. Used PCR to detect the genes encoding C. perfringens embedded in formalin and amplified the alpha, beta, and etoxin genes. Although Clostridium perfringens has died, However, the Clostridium perfringens gene is still intact, and thus the PCR assay can detect the presence of Clostridium perfringens death.
Bacteroides (Bacteroides), also known as Bacteroides genus, is a genus of Bacteroides, Gram-negative, non-spore, obligate anaerobic bacteria.
Bacteroides sits normally in the intestine, mouth, upper respiratory tract, and contraband of humans and animals. People's first understanding of Bacteroides is caused by its pathogenicity. With the passage of time and the deepening of research, especially the development of micro-ecology, people gradually come to realize that Bacteroides is a normal flora abundant in human and animals, accounting for more than 1/4 of the intestinal flora of adult individuals. Bacteroides and other flora and host have a complex and delicate relationship between the host's health plays an important role. Bacteroides at the same time is also a condition of pathogenic bacteria, when its normal micro-ecological balance is broken, it can lead to endogenous mention compound. So it can be said that Bacteroides is a contraband sword. On the one hand, it has a probiotic mechanism and on the other hand, it has a pathogenic mechanism.
Bacteroides is more important in Bacteroides fragilis and Bacteroides melanoidum.
