Dorsal Approach to the Caudal Pelvic Canal and Rectum Effect on Normal Dogs     

D. B. McKEOWN DVM    J. R. COCKSHUTT DVM    G. D. PARTLOW PhD  V. S. DE KLEER DVM 《Veterinary surgery : VS》1984,13(3):181-184

A dorsal surgical approach to the perineal area and rectum was made on 10 healthy, adult dogs. The rectococcygeal muscle was incised and the levator ani and external sphincter muscles were separated to the level of the caudal rectal nerve. All dogs were clinically normal throughout a 3 week postoperative observation period.  相似文献   

CHEMICAL WEED CONTROL IN BROADCAST-SEEDED FLOODED TROPICAL RICE     

S. K. DE  DATTA P. C. BERNASOR 《Weed Research》1973,13(4):351-354

Summary. Several new herbicides were tested for control of weeds in broadcast-seeded flooded tropical rice. Among the new herbicides, S-(2-methyl-l-piperidylcarbonyl-methyl)- O,O -di- n -propyl dithiophosphate (C-19490), S-(2-methyl-l-piperidylcarbonyl-methyl)- O,O -di- n -propyl dithiophosphate combined with 2-(1',2'-dimethylpropylamino)-4-ethylamino-6-methylmercapto- s -triazine [C-19490/C-18898 (C-288)], and N -secondary-butyl-4-tertiary-butyl-2,6-dinitroaniline (A-820) were highly selective in controlling Echinochloa crus-galli (barnyard grass) and other annual weeds under tropical conditions. S-(4-chlorobenzyl)- N,N -diethylthiol carbamate (benthiocarb) and N -(butoxymethyl)-2-chloro-2',6'-diethylacetanilide (butachlor) continued to look promising in our experiments. Only butachlor is widely used in Asia.

Screening of 170 Peruvian plant species for allelopathic activity by using the Sandwich Method     

CECILIA INES ONO MORIKAWA  RIE MIYAURA  MARIA DE LOURDES TAPIA Y FIGUEROA  ELSA LILIANA RENGIFO SALGADO  YOSHIHARU FUJII 《Weed Biology and Management》2012,12(1):1-11

Peru is one of the 20 botanically extremely diverse countries in the world, with >17 000 flowering plants, of which 30% are endemic. So far, no systematic research has been conducted on the screening of the allelopathic plants. In this study, the allelopathic activity of 170 species from 61 families of Peruvian plants that were collected from the three main regions of Peru – the Costa (Pacific coastline), the Sierra (Andean mountains), and the Selva (Amazonian rainforest) – was evaluated. The allelopathic activity was determined by the Sandwich Method, which can evaluate the activity of leaf leachates. The species that were found to be highly inhibitory in this screening, under the criterion of >90% inhibition of the radicle of lettuce (Lactuca sativa) seedlings, were Aristeguietia ballii and Diplostephium foliosissimum (Asteraceae) and Spondias mombin (Anacardiaceae). All of these species are native plants from Peru. This study gives a strong clue regarding the potential of isolating potent allelochemicals from these plants in the future.  相似文献   

吉林省农村居民消费结构的研究

共表达O型FMDV衣壳蛋白和绿色荧光蛋白重组腺病毒的构建     

刘蒙蒙  杨德成  周国辉  梁特  于力 《中国预防兽医学报》2012,34(2):83-86

为构建表达O型口蹄疫病毒(FMDV)的P12A3C基因及GFP基因的重组腺病毒rAdV-P12aEGFP2a3C,本研究以FMDV的2A基因序列为Linker,将报告基因EGFP插入FMDV的P12A与3C之间。重组腺病毒感染HEK-293细胞后可以观察到绿色荧光,表明EGFP蛋白获得表达。应用FMDV的VP2单克隆抗体4B2对重组病毒感染细胞进行western blot检测,反应条带与FMDV衣壳蛋白VP0和VP3的分子量大小相符,表明FMDV的完整衣壳蛋白和3C蛋白酶也均获得表达,而且EGFP的插入并未影响P1蛋白的表达和3C蛋白酶对P1的正确切割。重组腺病毒的生长特性分析表明,EGFP的插入也未影响该重组腺病毒的增殖特性。上述研究结果显示,表达FMDV衣壳蛋白P12A3C的重组腺病毒可以作为载体,以2A蛋白作为Linker表达一个小分子蛋白,为改进以腺病毒为载体的口蹄疫基因工程疫苗提供了新思路。  相似文献
