The key to feature extraction is to select the optimal feature combination from all the features. In this study, the optimal color feature combination,{/G,(R+4G+B)/6, H variance, S variance}, is selected using genetic neural network at first. Then the main texture features including the mean, variance, energy and entropy of the cooccurrence matrix, the secondary texture features including the maximum frequency number, absolute uniform, inertia and importance of the co-occurrence matrix are extracted.

在此基础上，提出适合多阈值和小目标图像分割的免疫遗传图像分割方法，该方法借鉴了生物免疫系统自调节、抗原识别和记忆功能，并结合了遗传算法对图像进行自适应区域的阈值分割，改善了遗传算法优化复杂问题时存在收敛速度慢和易陷于局部最优的不足，克服了传统阈值分割方法对目标大小的限制，是一种新型的有效的图像分割方法。

Materials and 64 dust acarid allergic rhinitis outpatients were randomly divided into 2 groups, 31 patients in the control group were treated with general immunotherapy, 33 patients in the trial group were treated with NHD, the serum level of IL-4, IL-5 was detected by ELISA.

常年性变应性鼻炎患者64例，随机分为常规免疫治疗组31例，标准化尘满变应原疫苗治疗组33例，比较两组患者在接受免疫治疗后的疗效及血清IL-4、IL-5水平。

According to the latest research in priority and deficiency of evolution algorithm and the influence of biologic immunity, a new algorithm-immunity algorithm is advanced.

在研究现有进化算法的优越性与存在不足的基础上，受生物免疫原理的启发，提出了一种新的算法--免疫算法。

The spleen has much more functions besides blood filtering and storing, haematogenesis, and immunization, and its immune function has characteristics of twoway and phase.

脾脏是机体免疫神经内分泌网络调节中心的一个重要组成部分，它不仅具有滤血、免疫、造血和储血等功能，而且其免疫功能具有&双向性&和&时相性&的特点。

A better understanding of the function of spleen has been gained recently, owing to the in-depth studies on the structure, cellular function, secretion and innervation of spleen. It is generally accepted that the spleen is the important part of the regulation network between immune, nerve and endocrine system. The spleen has much more function besides blood filtering and storage, haematogenesis, and immunization, and its immune function has characteristics of \\\\\\\"two-way\\\\\\\" and \\\\\\\"phase\\\\\\\".

近年来，随着对脾脏组织结构、细胞功能、分泌功能和神经支配的深入研究，对于脾脏的功能有了更加深入的认识：脾脏是机体免疫-神经-内分泌网络调节中心的一个重要组成部分，其功能并不仅仅局限于滤血、免疫、造血和储血等，而且脾脏的免疫功能具有&双向性&和&时相性&的特点。

In contrast, the improv ement of HCV core-specific CTL activity with an IL-2-producing construct coimmuniza tion was not obvious, which maybe resulted from the low-level expression of IL -2 vector-pDOR. CONCLUSION DNA vaccine of HCV combined with IL-12 expr essive plasmid can get better therapeutic effects, and it might represent an approach to the gene therapy against HCV infection.

佐以不同的细胞因子，可增强基因疫苗诱生的免疫应答强度，可能使机体对基因疫苗的免疫应答朝着有利于优先诱导CTL免疫应答，清除病原体的方向发展。

Methods Lewis rats were immunized with the protein extracted from electric organ of Narcine timilei, the clinical manifestations were observed every day, and repetitive nerve stimulation,single fiber electromyography and the levels of acetylcholine receptor antibody were detected on the 49th days post immunization. The content of the protein extracted from electric organ of Narcine timile was 35.4 mg/mL, and the protein could respond with AChRAb from the serum of seropositive myasthenia gravis patient.

参照徐氏法从丁氏双鳍电鳐的电器官提取AChR蛋白，并采用Folin-酚试剂法及酶联免疫吸附法检测提取蛋白的含量及活性；以提取的蛋白主动免疫Lewis大鼠，每天观察其临床表现，并于免疫后7周进行低频重复电刺激、单纤维肌电图及血清中AChRAb水平的检测。
