To the descending colon and rectum , because of the pH increased the activity of proteolytic enzymes increased, so it is generally believed that the ascending colon where is the best delivery site for protein peptide drugs.

至降结肠及直肠等处，由于 pH 值升高，蛋白水解酶的活性明显增强，故一般认为升结肠处为蛋白多肽类药物的最佳给药部位。

The results show that all the hmgr genes from pigs, cattle and chickens are astable enzyme proteins with the same gene sequence characteristics and encoding protein and physical and chemical properties; all the amino acid sequences have a high degree of homology, containing two conservative HMG-CoA binding motifs and two NADPH binding motifs; all the amino acid sequences, containing signal peptide, are secreted proteins; they are all hydrophobic transmembrane proteins with five transmembrane domains; random coil and α-helix are the main structural elements in the HMGR polypeptide chain; all the predictions of three-dimensional structure are V- shaped; there are more closer evolution relationship between the HMGR gene from pigs and cattle.

结果表明：猪、牛和鸡HMGR基因序列特点及编码蛋白质理化性质基本相同，均属不稳定类酶蛋白；保守结构域氨基酸序列具有高度的同源性，均含有保守的2个β-羟基-β-甲基戊二酸单酰辅酶A结合基序和2个还原性烟酰胺腺嘌呤二核苷酸结合基序；均有信号肽，属分泌型蛋白质；属于跨膜的疏水性蛋白，均有5个跨膜结构域；无规则卷曲和α-螺旋是HMGR多肽链中的主要结构元件；三维结构预测都呈"V"字形；猪和牛HMGR基因的进化关系最近。

The OsCMO contains 10 exons and 9 introns and encodes a protein with 410 amino acids,which shows 62﹪, 51﹪, 51﹪, 51﹪ and 50﹪ identities in amino acids to CMOs from Arabidopsis thaliana,Atriplex hortensis, Amaranthus tricolor, Suaeda liaotungensis and Beta vulgaris respectively. Semi-quantitative RT-PCR assay revealed OsCMO was significantly up-regulated in the rice seedlings under salt, cold and drought stresses. It suggests that OsCMO might play an important role in rice responses to abiotic stresses.

该基因含有10个外显子和9个内含子，其开放阅读框编码一条长为410个氨基酸残基的多肽，与拟南芥、山菠菜、苋、碱蓬和甜菜等植物的胆碱单加氧酶的氨基酸序列的一致性50﹪～62﹪。mRNA分析表明OsCMO基因在水稻幼苗组织中的表达受高盐、低温和干旱等胁迫的上调诱导表达，表明该基因可能在抵御非生物胁迫中发挥重要作用。

Objective To detect the level of anti-SSA-60 000 autoantibody in patients with autoimmune diseases as well as its assay methods.

目的 建立便捷的检测抗干燥综合征A抗原(分子量为60 000的多肽成分)的自身抗体的方法，以利于疾病的早期诊断和病程监控。

It is possible that the rLL37 is expressed in procaryotic cell by fusion and it possesses a strong bactericidal activity.

改良的人源性LL37多肽以原核细胞进行融合表达是可行的，并具有较强的杀菌活性。
