针对兔子序列的生成提出了一种基于链表的实现方法,并采用C语言编程实现.选取不同的起点,该方法可生成大量0—1序列,能较好地应用于数字水印中决策等需求.同时,该方法能更形象地表达兔子序列的生成过程,进一步体现链表的动态存储特性,可作为"数据结构"与"程序设计"等课程的实践案例. 相似文献

为探讨虾血对抑制兔耳瘢痕增生的影响,以成年新西兰大耳白兔建立兔耳增生性瘢痕模型,将增生性瘢痕块分为对照组(A组)、虾血治疗组1(B组)和虾血治疗组2(C组),以不同组瘢痕组织石蜡包埋HE染色,观察虾血治疗对瘢痕组织中成纤维细胞、胶原纤维的影响。结果表明:肉眼观察虾血治疗组的瘢痕较空白对照组有改善;光镜下见虾血治疗组成纤维细胞减少,胶原纤维含量降低且排列较规则有序,差异具有显著性(p<0.001);虾血治疗组2微血管均数较少,抑制疤痕增生效应最好(p<0.01);虾血可能具有抑制兔耳增生瘢痕的形成及瘢痕组织增生的作用。 相似文献

Defensin is one of preserved ancient host defensive materials formed in biological evolution. As a regulator and effector molecule, it is very important in animals' acquired immune system. This paper reports the defensin gene from the mixed liver and kidney cDNA library of abalone Haliotis discus hannai Ino. Sequence analysis shows that the gene sequence of full-length cDNA encodes 42 mature peptides (including six Cys), molecular weight of 4 323 Da, and pI of 8.02. Amino acid sequence homology analysis shows that the peptides are highly similar (70% in common) to other insects defensin. Because of a typical insect-defensin structural character of mature peptide in the secondary structure, the polypeptide named Haliotis discus defensin (hd-def), a novel of antimicrobial peptides, belongs to insects defensin subfamily. The RT-PCR result of Haliotis discus defensin shows that the gene can be expressed only in the hepatopancreas by Gram-negative and positive bacteria stimulation, which is ascribed to inducible expression. Therefore, it is revealed that the Haliotis discus defensin gene expression was related to the antibacterial infection of Haliotis discus hannai Ino. 相似文献
