在过去的25年中,研究动物行为的科学—动物行为学(Ethology),业已发展成为畜牧学中一门成熟的分支学科。这一领域中的研究活动和教学素材已显示出不断增长的迹象。但是,总体说来还是不完整的,在动物行为学原理的认识方面以及畜牧科学工作者和生产者应用这些原理方面,还留下很多空白。本文重点放在近代和当前在动物行为学研究中被选择的若干领域,试图在研究的深度和在动物管理中最终应用这些资料的潜在可能两方面做出说明。有关今后关注的问题也做讨论。

AIM To investigate the effects of TRH in DVC on motility of the gallbladder in rabbits. METHODS After fasted for 15h - 18h , rabbits were anesthetized with urethane (1 0g/kg) . Gallbladder pressure (GP) was measured by a frog bladder perfused with normal saline. RESULTS After microinjection of TRH (8 8nmol, 1μl ) into DVC, GP was raised and the frequency of phasic contraction of gallbladder (FPCGB) increased. All the doses of TRH (0 13, 0 25, 0 50, 0 80, 1 30nmol , 1μl ) injected into DVC could excite the motility of gallblader. As the dose of TRH was enlarged, the amplitude and duration of the reaction increased. Effects of TRH in DVC on motility of the gallbladder could be completely abolished by atropine ( 0 2mg/g , i.v.) or vagotomy, but could not be inhibited by phentolamine iv (1 5mg/g) or propranolol iv (1.5mg/g) or by transecting the spinal cord. CONCLUSION Thyrotropin releasing hormone in DVC can excite motility of gallbladder. This effect was mediated by vagus nerves and peripheral M receptor. Its physiol.gical significance may be related to maintaining the phasic contraction of gallbladder in interdigestive period.

文中对牛、羊、猪的卵泡生长和排卵,丘脑下部—垂体—卵巢的互作,黄体功能和发情周期的调节等问题的现有观点和新的提法进行了综述。在整个发情周期中,卵泡持续不断地生长、退化和被其他的大卵泡代替。在这个过程中,卵巢内部因素似乎起重要作用。排卵前卵泡内雌二醇的浓度在LH的排卵前高峰到来之前一直增长,然后急速下降。人们提出了一个所谓控制卵泡类固醇合成的二细胞—二促性腺激素的模式,这个概念还提出,卵泡的雄激素是通过A5通路合成的,细胞内高浓度的雌二醇在LH峰出现之前抑制着孕酮的生产。有人认为卵巢组织能生产非类固醇的FSH和丘脑下部激素的抑制剂。我们的现代概念大概只是对黄体退化时发生的情况的部分解释。有例证说明前列环素（prostacyclin）和PGE2在黄体生长期分别对母牛和绵羊具有促黄体的作用。最近的一些研究认为催产素对牛、羊的黄体退化可能具有生理功能。磷酯的甲基化,看来对LH刺激黄体细胞腺甙酸环化酶（adeny-late cyclase）和后来孕酮生产的机制,是一个重要的调节步骤。促性腺激素的分泌有明显的间歇,依周期阶段和生殖状态而变化。引用的文献与下述观点是相吻合的,即在GnRH的脉冲式释放的连续影响和雌激素的控制下,LH的脉冲式释放量也依次逐渐增多,从而产生了排卵前的LH峰。已

Immuno-suppressive protein was generated in spleen and lymph node and released into serum in mice and rats under stress, which had strong suppressive effects on T and B lymphocyte proliferation. The present study showed that the serum from stressed mice presented a significant decrease in lymphocyte proliferation at 1, 12, 24, and 48 h after stress. There was not significant suppressive effect at 96 h. The half life of biological effect was 21.6

Immuno-suppressive protein, with a molecular weight of 155 and 370 ku, was generated in spleen and lymph node in stressed rats. It strongly inhibited lymphocyte proliferation. The results of activity assay, molecular weight determination and histological localization all demonstrated that under stress the immuno-suppressive protein was also generated in intestinal mucosa of rats.

The mechanism for transmission of sensory information concerning a specific sensory modality or submodality can be called a sensory channel, including the receptors, sensory pathways and the parts of the central nervous system that further process the sensory information . A certain sensory channel can be activated by a suitable stimulus. Sensory information is transduced by sensory receptor and is further transferred into central nervous system. The characteristics of a modality or submodality are mainly determined by the properties of the corresponding sensory receptors. However, besides the receptor properties, are there any other factors which have influence on the properties of a sensory modality? Is there a kind of gating mechanism existing which could selectively control the inputs of sensory information based on different sensory channels? Here we are trying to answer the above questions by studying the functional relationships between different mechanosensory modalities of leech.

A 4.34 liter two stage air lift photobioreactor incorporating Anabaena variabilis ATCC29413 mutant PK84 was used to study H 2 production. Results showed that H 2 production increased with increasing light intensity from 47 μE/(m 2·s) up to 190 μE/(m 2·s), but that further increase of light intensity decreased the H 2 production because of the inhibition due to the high pO 2. The data also indicated that longer argon gas charge resulted in more H 2 produced due to the increase of nitrogenase activities and heterocyst frequency, and that more than 1.3 L net H 2 was produced from this computer controlled photobioreactor.

An initial attempt reveals parameters of marked electric synapse on AP perceptive neuron of leech. The width of gap between marked AP and either neuro- or glio-process is 2-3 nm, the diameter of the hexagonal array of connexion is 8-9 nm with a central pole of 2-2.5 nm, the same as the structure of annular lamellar bodies internalized by AP-glia processes in the AP.
