Surgical repair of a peritoneopericardial diaphragmatic hernia in a pregnant dog

Objective: To describe the surgical repair and pre‐ and postoperative management of a peritoneopericardial diaphragmatic hernia (PPDH) in a pregnant dog. Case summary: A pregnant dog was presented for vomiting, lethargy, and pale mucous membranes. Pulsus paradoxus was noted on physical examination. The dog was diagnosed with a PPDH via thoracic radiographs, abdominal ultrasound, and an echocardiogram. The hernia was surgically repaired and the dog received supportive medical care until the puppies were old enough to be delivered via cesarean section. The mother and all puppies survived. New or unique information provided: This is the first report that describes the surgical repair and postoperative management of a PPDH in a pregnant dog.     

水稻根面争论产碱菌1AG4的分离、鉴定及其固氮和对病原菌的拮抗作用

从水稻(Oryza sativa L.)越光根面分离到一株固氮菌株 1AG4,经生理生化特性鉴定,归类为争论产碱菌(Alcaligenes paradoxus)。1AG4 的固氮酶乙炔还原活性(ARA)为13.06 C2 H4 nm ol/m l·h,固定15N2 活性(N2 FA)为 2.052 15N a.e.% ,表明 1AG4 具有较强的固氮能力。平皿拮抗试验证明 1AG4可拮抗包括水稻三大病害病原菌在内的 14 种植物病原菌(Xanthom onas oryzae pv. oryzae ZHE173、Thanatephorus cucum eris、Piricularia oryzae Cavara、Alternaria longipes(Ellis etEverhart) Tisdale etW adkins、Cochliobolus sativus、Colletotrichum agaves Cavara、Colletotrichum lagenarium (Passerini)Ellis et Halsted、Colletotrichum panacicola Uyeda et Takim oto、Fusarium oxysp orum f. niveum 、Helm inthosporium turcicum Passerini、Phytophthora parasitica Destur、Verticillium albo-atrum Reinkeet Berthold、Phytophthora m elonis Katsura、Pseudom onas solanacearum Sm ith)的生长     

大牙土天牛消化道系统的形态解剖

本文系统地研究了大牙土天牛（ＤｏｒｙｓｔｈｅｎｅｓｐａｒａｄｏｎｘｕｓＦａｌｄｅｒｍａｎｎ）消化道的形态构造。通过解部发现其消化道包括前、中后肠。前肠为直管状，无嗉囊及前胃。中肠占消化道的６１％～６９％，前端膨大，后端细并转折为三段。后肠较短，具隐肾结构。     

大牙土天牛的初步研究

本文在１９９４年以来调查、观察、饲养大牙土天牛的基础上，对其各虫期形态特征进行了详细描述，对其生物学特性进行了较系统的观察和研究，并提出可行的防治建议。     

Experimental Assessment of a New rDNA-Based Method for the Identification of Merluccius capensisand Merluccius paradoxusin Commercial Products

Abstract

There has been great interest in the identification of Cape hakes, Merluccius capensisand Merluccius paradoxus, by non-morphological methods. The information provided by a ribosomal DNA-based method will allow investigators to precisely identify the species of Cape hake in commercial samples. The first test consisted in the PCR amplification of a 193 bp fragment from the ITSl-rDNA to assess the presence of DNA from hakes. Positive tests were followed by a second test consisting of the amplification and digestion of the PCR fragment from the ITS1 sequence, to determine the identity of the commercial species. A single restriction enzyme provided full diagnosis of the species present in the samples. Since this new method is simple, reliable, and reproducible and can be performed in a working day, it allows the genetic traceability of Cape hakes across the food chain. This could also help management of the fisheries.     

水稻根面争论产碱菌1AG4的分离、鉴定及其固氮和对病原菌的拮抗作用

 从水稻(Oryza sativa L.)越光根面分离到一株固氮菌株1AG4,经生理生化特性鉴定,归类为争论产碱菌(Alcaligenes paradoxus)。1AG4的固氮酶乙炔还原活性(ARA)为13.06 C₂H₄ nmol/ml°h,固定¹⁵N₂活性(N₂FA)为2.052 ¹⁵N a.e.%,表明1AG4具有较强的固氮能力。平皿拮抗试验证明1AG4可拮抗包括水稻三大病害病原菌在内的14种植物病原菌(Xanthomonas oryzae pv.oryzae ZHE173、Thanatephorus cucum eris、Piricularia oryzae Cavara、Alternaria longipes(Ellis et Everhart) Tisdale etW adkins、Cochliobolus sativus、Colletotrichum agaves Cavara、Colletotrichum lagenarium(Passerini) Ellis et Halsted、Colletotrichum panacicola Uyeda et Takimoto、Fusarium oxysporum f.niveum、Helminthosporium turcicum Passerini、Phytophthora parasitica Destur、Verticillium albo-atrum Reinkeet Berthold、Phytophthora melonis Katsura、Pseudomonas solanacearum Smith)的生长
