动物外伤的观察治疗

在对甲壳素及壳聚糖的制法作了一些试验的基础上，用壳聚糖自制成外伤料用于动物外伤愈合方法的实验，取得较好的效果。     

动物生理信号计算机自动测试与分析系统在药物毒理研究中的应用

从中草药中寻找新药已成为当今药学界的研究热点。新药在进入临床前的实验时,动物的毒理研究是必不可少的,而动物生理信号的测试是其毒理研究中重要的组成部分。长期以来测试动物生理信号所沿用的描笔式记录仪存在着许多缺陷。我们结合药学、电子工程学和计算机软件等多学科的综合优势,研制了一套计算机控制的、用于动物生理信号的检测与分析系统,并用大鼠进行了实验验证,实验结果表明该系统通用性强、自动化程度高、存贮信息量大、所获实验数据更为科学和合理。计算机的引入将会促进中草药药理和毒理传统研究手段的更新和发展。     

畜牧业和谐发展之路--绿色生态养殖

绿色畜牧业乃畜牧业发展的必然趋势。现在的养殖业存在许多问题，畜产品残留物及动物排泄物影响动物本身、人类和环境，带来了一系列危害。采取措施发展绿色生态养殖，才能促进畜牧业和谐协调发展。     

几种脊椎动物红细胞血型的比较研究

采用两种方法对脊椎动物各纲的代表动物小白鼠、家兔、家鸽、蟾蜍、鲫鱼的红细胞血型进行了研究 .方法一 :采用人类抗A、抗B标准血清与上述动物的红细胞进行反应 ,结果均未出现凝集现象 ,表明 :这几种动物的红细胞膜上 ,没有与人类抗A、抗B标准血清起反应的A凝集原和B凝集原 .方法二 :采用同种动物的血清与同种动物不同个体的红细胞进行反应 ,结果 :上述几种动物的红细胞与同种内不同个体的血清均不发生凝集反应 .     

土壤侵蚀造成徐连山丘区农业环境恶化及其逆转途径

长期的土壤侵蚀使徐连山丘区农业环境不断恶化:土层变薄、肥力降低、砂砾增多、裸岩面积扩大和旱涝灾害加剧。防治的基本对策应为:在山丘区经济建设中加强水土保持工作,加强以坡改梯为中心的农田基本建设,加速植被覆盖并进而加强耕作管理。     

蚯蚓和蚓粪喂养革胡子鲶的试验研究

动物蛋白饵料不足,是影响革胡子鲶产量的原因之一,本试验表明,蚯蚓和蚓粪可作为革胡子鲶的优良动物蛋白饵料.用蚯蚓和蚓粪喂养革胡子鲶,既可提供各种必需氨基酸、维生素和微量元素,还可促进池塘中有益浮游生物的生长,改变水质,从而提高质量,增加经济效益.     

肝再生

肝脏在受到损害或切除之后,可以显示出强大的再生能力。肝再生这一现象早已被人们发现并研究。肝脏再生的启动因素有哪些,又是如何适时终止的?在肝再生过程中,哪些基因的表达发生了变化?哪些信号通路参与了肝再生过程?这些问题一直是研究者关注的焦点。本文将对肝再生研究的这些热点问题进行综述。     

Histories of molecules: Reconciling the past

Molecular data and methods have become centrally important to evolutionary analysis, largely because they have enabled global phylogenetic reconstructions of the relationships between organisms in the tree of life. Often, however, molecular stories conflict dramatically with morphology-based histories of lineages. The evolutionary origin of animal groups provides one such case. In other instances, different molecular analyses have so far proved irreconcilable. The ancient and major divergence of eukaryotes from prokaryotic ancestors is an example of this sort of problem. Efforts to overcome these conflicts highlight the role models play in phylogenetic reconstruction. One crucial model is the molecular clock; another is that of ‘simple-to-complex’ modification. I will examine animal and eukaryote evolution against a backdrop of increasing methodological sophistication in molecular phylogeny, and conclude with some reflections on the nature of historical science in the molecular era of phylogeny.     

Can we agree on an ecological classification of subterranean animals?

That the ties between any obligate subterranean species and the hypogean environment depend on the interplay of a species' own physiological characteristics and all of the ecological characteristics of the adjacent epigean habitat(s), including biotic factors, has been emphasized. The reasons why troglomorphy cannot be included within criteria for classifying cave dwellers have been demonstrated. After a review of historic classifications, standardized definitions of the most widely used terms are proposed. The most easily recognized are four categories which are terminological approximations of the classic Schiner‐Racovitza terminology: (1) troglobiont is a species or population, strictly bound to a hypogean habitat; (2) eutroglophile is an essentially epigean species, but able to maintain a permanent subterranean population; (3) subtroglophile is inclined perpetually or temporarily to inhabit a subterranean habitat but is bound to the surface for some biological functions (e.g. feeding); (4) trogloxene is a species only occurring sporadically underground.
