今年是我国近代生物学的主要奠基人、中国动物学会创始人、《动物学报》创始人和第一任主编秉志先生诞辰120周年。10月18日,中国动物学会和中国科学院动物研究所在京举办了秉志先生诞辰120周年纪念会。我虽无缘亲聆秉志先生的教诲,但通过秉志先生身边工作人员和他的学生们的缅怀感言,通过这篇《秉志传略》,以及在承担《所史》的编撰过程中对许多史料的查阅,不禁深深为他强烈的爱国热忱、渊博的知识、在维护科学家的良知方面所表现出来的非凡勇气和胆识所感动,并从中受到深刻的教育。值此纪念秉志先生诞辰120周年之际,不揣浅陋,将它写出来,以表达我对秉志先生的敬仰之情。 相似文献

我国五十五年来的兽类学 总被引:1,自引:0,他引:1
中国动物学会成立55年了,这55年来,我国的兽类学的发展过程是怎样呢?愿就个人所见,提一些不成熟的看法。 近代兽类学在我国起步并不晚,20年代中期,秉志先生前后发表过有关江豚形态及老虎骨学等方面文章有9篇之多;20年代后期石声汉先生发表过以傜山兽类调查为主的4篇论文。但是后来二位都不作兽类学的研究,兽类学的工作形同夭折。到1934年,也就是中国动物学会成立那年,兽类学又重新兴起,何锡瑞先生连续发表4篇论文,傅桐生、刘承钊等先生在1937年以前也作了一定的工作。刘先生刺猬 相似文献

鲤鱼(Cyprinus carpio L.)是我国常见的淡水鱼类之一,在很多地方都可以找到,我国著名生物学家秉志先生,对鲤鱼的形态学有较系统和深入的研究,他著有《鲤鱼解剖》和《鲤鱼组织》等,但在秉志先生的工作中,因当时条件不具备,尚未使用电镜与超速离心分析技术进行工作。本文著者已用扫描电子显微镜对鲤鱼组织按秉志先生所著《鲤鱼解剖》所定的系统进行过观察,提出了一些新的资料,可能对动物学、水生生物学、水产学以及脊椎动物形态学的研究,有一定的参考价值。但对鲤鱼组织在分子水平上进行分析,尤其用超速离心分析的方法,测定它的沉降系数,尚未有人报道。本实验所用样品为鲤鱼 DNA,将其溶于0·2M 氯化钠水溶液中,PH6·5,浓度为1毫升 相似文献

In experiments on Black Sea skates (Raja clavata), the potential of the receptor epithelium of the ampullae of Lorenzini and spike activity of single nerve fibers connected to them were investigated during electrical and temperature stimulation. Usually the potential within the canal was between 0 and –2 mV, and the input resistance of the ampulla 250–400 k. Heating of the region of the receptor epithelium was accompanied by a negative wave of potential, an increase in input resistance, and inhibition of spike activity. With worsening of the animal's condition the transepithelial potential became positive (up to +10 mV) but the input resistance of the ampulla during stimulation with a positive current was nonlinear in some cases: a regenerative spike of positive polarity appeared in the channel. During heating, the spike response was sometimes reversed in sign. It is suggested that fluctuations of the transepithelial potential and spike responses to temperature stimulation reflect changes in the potential difference on the basal membrane of the receptor cells, which is described by a relationship of the Nernst's or Goldman's equation type.I.

Evolution of living organisms is closely connected with evolution of structure of the system of regulations and its mechanisms.
The functional ground of regulations is chemical signalization. As early as in unicellular organisms there is a set of signal
mechanisms providing their life activity and orientation in space and time. Subsequent evolution of ways of chemical signalization
followed the way of development of delivery pathways of chemical signal and development of mechanisms of its regulation. The
mechanism of chemical regulation of the signal interaction is discussed by the example of the specialized system of transduction
of signal from neuron to neuron, of effect of hormone on the epithelial cell and modulation of this effect. These mechanisms
are considered as the most important ways of the fine and precise adaptation of chemical signalization underlying functioning
of physiological systems and organs of the living organism 相似文献
