Agricultural Biotechnology 2018年第4期7卷 110-114,117页

作者： Huibin shi Zhilong TIAN Yuqin wang Zhibo WU Fang YANG jianping wang Mingxing CHU CaiHong WEI College of Animal Science and Technology Henan University of Science and TechnologyLuoyang 471003China Mutton Sheep Breeding Engineering Technology Research Center of Henan Province Luoyang 471019China Key Laboratory of Animal Genetics and Breeding and Reproduction of Ministry of Agriculture Institute of Animal ScienceChinese Academy of Agricultural SciencesBeijing 100193China

In many seasonally breeding species, photoperiod is an important factor involved in reproduction. Capra hircus breeds are normally considered short-day breeders. An experiment was carried out to evaluate whether or not photoperiodic regimens influence circulating hormone levels （prolactin, melatonin, thyrotropin stimulating hormine, luteinizing hormone,follicle stimulating hormone） of Henan huai local goat exposing to different photoperiodic regimens. The results showed that plasma levels of prolactin, melatonin, thyrotropin stimulating hormine, luteinizing hormone and follicle stimulating hormone were higher in the 8 L∶ 16 D photoperiodic regimen than that in the 16 L∶ 8 D photoperiodic regimen. Levels of those hormones decreased on day 7 and day 28 when the 16 L∶ 8 D photoperiodic regimen was used continuously. It was concluded that serum concentrations of the hormones increased in summer when short day （8 L∶ 16 D） was used and decreased when the goats were transferred from short day for 42 d to long day exposure for 28 d. We suggest that in summer, levels of hormones changing may be due to short day animals. Changing of related hormones is still determined by the mechanism of internal regulation of short day animal s exposure to light changes. Shortening light may also help increase the reproductive activity of goat and thus increase productivity.

This study established a dog model of acute multiple cauda equina constriction by experimental constriction injury （48 hours） of the lumbosacral central processes in dorsal root ganglia neurons. The repair effect of intrathecal injection of brain-derived neurotrophic factor with 15 mg encapsulated biodegradable poly（lactide-co-glycolide） nanoparticles on this injury was then analyzed. Dorsal root ganglion cells （LT） of all experimental dogs were analyzed using hematoxylin-eosin staining and immunohistochemistry at 1,2 and 4 weeks following model induction. Intrathecal injection of brain-derived neurotrophic factor can relieve degeneration and inflammation, and elevate the expression of brain-derived neurotrophic factor in sensory neurons of compressed dorsal root ganglion Simultaneously, intrathecal injection of brain-derived neurotrophic factor obviously improved neurological function in the dog model of acute multiple cauda equina constriction. Results verified that sustained intraspinal delivery of brain-derived neurotrophic factor encapsulated in biodegradable nanoparticles promoted the repair of histomorphology and function of neurons within the dorsal root ganglia in dogs with acute and severe cauda equina syndrome.

CONDUCTIVE LAYER IN THE CRUST IN NORTH CHINA AND ITS RELATION TO CRUSTAL TECTONISM

引用

Science in China,Ser.B 1984年第10期27卷 1093-1104页

作者：刘国栋史书林王宝钧 Institute of Geology State Seismological Bureau Beijing

Since 1976 observations of more than forty magnetotelluric （MT） sites have been carriedout in North China, and the conductive layer at the depths of 15-25 km with the longitudinaleonduetances of several hundreds to more than one thousand siemens have been found beneathmost of the MT sites. In this region, tho depth of the conductive layer is very close to thatof the minimum velocity layer determined by DSS. Most earthquakes have occurred above thislayer, and a lot of normal faults have vanished above this layer, too. The area, where thedepth and longitudinal conductance of the conductive layer are shallow and high, has a higherheat flow and stronger tectonism during the Cenozoic time. The authors suggest that the con-duetive layer in the crust boneath the plain might result from partial melting of the felsieminerals, while that beneath the surrounding areas from dehydration of the minerals withcrystal water.

Hu Sheep is a local sheep breed in the plain of Taihu, China. Due to the natural conditions in Taihu and human domestication, Hu Sheep is gradually featured with high adaptability, fast growth rate, early maturity and high productivity, which make them to be a unique and rare breed of sheep. In the present study, an experiment was conducted by means of instantaneous scan sampling, focal animal sampling and all-occurrence sampling to learn about Hu Sheep's behavior and activity pattern under certain feeding management and ecological condition. The result showed that the activity time budgets for several behaviors were different between rams and ewes, with respect to feeding (rams 30.60% vs. ewes 33.23%), ruminating (33.43% vs.35.30%); sleeping (19.92% vs. 13.69%), standing (4.13% vs. 5.26%), moving (8.10% vs. 7.46%), and other behaviors (3.86% vs.5.06%). A circadian activity rhythm was shown in some behaviors; e.g., total feeding time was greater in the daytime than at night, whereas resting time showed the opposite tendency. Moving mostly occurred in the daytime, and ruminating mainly occurred at night. Additionally, feeding activity occurred 32.22 times per day in rams and 31.73 times per day in ewes, whereas ruminating activity after feeding occurred 19.83 times per day in rams and 24.34 times per day in ewes. For each food bolus,the average ruminating time was 51.22 s in rams and 49.52 s in ewes, with 68.22 bouts of rumination per day in rams and57.35 bouts of rumination in ewes. By conducting the experiment, we studied and grasped the local Hu Sheep's main behavior and regularity which are of great significance on improving the feeding management and reducing diseases.

2008年汶川8.0级地震沿龙门山断裂带内的映秀—北川断裂和灌县—安县断裂产生了近300 km的同震地表破裂带。震后地质科学考察发现地表变形以逆冲为主,并伴有右旋走滑。地震地表破裂带大多沿古生代碳质泥岩、页岩和三叠系煤系地层内的滑动面出露地表,这些软弱地层为地震破裂带冲到地表提供了超低摩擦滑动带。我们发现在同震垂直和水平位错达6m左右的地表破裂带,地震的同震滑动发生在厚度约0.5～2cm的狭窄滑动带内,以发育新鲜的灰色断层泥为特征,这些断层泥是地震断层快速滑动过程中岩石—流体相互作用的结果。
