AIM: To assess the benefit of inducing emesis in dogs that have ingested rodenticide bait containing brodifacoum (BDF), by determining the amount of BDF in bait recovered from the vomitus relative to the estimated amount consumed.
METHODS: Between 2014 and 2015 samples of vomitus from seven dogs that ingested rodenticide baits containing BDF were submitted by veterinarians in New Zealand. All seven dogs had been given apomorphine by the veterinarian and vomited within 1 hour of ingesting the bait. Some or all of the bait particles were retrieved from each sample and were analysed for concentrations of BDF using HPLC. Based on estimations of the mass of bait consumed, the concentration of BDF stated on the product label, and the estimated mass of bait in the vomitus of each dog, the amount of BDF in the vomited bait was calculated as a percentage of the amount ingested.
RESULTS: For five dogs an estimation of the mass of bait ingested was provided by the submitting veterinarian. For these dogs the estimated percentage of BDF in the bait retrieved from the vomitus was between 10–77%. All dogs were well after discharge but only one dog returned for further testing. This dog had a normal prothrombin time 3 days after ingestion.
CONCLUSIONS AND CLINICAL RELEVANCE: The induction of emesis within 1 hour of ingestion can be a useful tool in reducing the exposure of dogs to a toxic dose of BDF. The BDF was not fully absorbed within 1 hour of ingestion suggesting that the early induction of emesis can remove bait containing BDF before it can be fully absorbed. 相似文献

Nature's Concept. The ‘New Agriculture’ amidst Ecology,Economy and the Demythologization of the Gene
From worldwide discussions about the limits of agriculture has arisen a powerful vision of sustainable development. Phrases like ‘limitation’, ‘sustainability’, ‘sufficient supply’, ‘fair distribution’ and ‘productivity of resources’ are no longer hindrances but guidelines for a fairer and safer world. ‘Nature's Concept' focuses on biological and ecological principles. On this basis, criteria of action have to be defined in order to determine long‐term economic consequences of agri‐production. The costs of destruction of natural resources, such as reduction of genetic resources, changes to the world climate and soil degradation, are inestimably large. The long‐term effects show the real substance of the agri‐shift and the demands on research. The solution for sustainable agriculture is more than ever a scientific development of ‘tools’ for a sensible management of resources. Gene technology may be an option to reduce the ecological risks of agriculture, especially those of devastating land use. For this purpose, new education programmes with international links and interventions by states are crucial in order to solve conflicts when short‐term interests interfere with long‐term ecological values. The international agri‐centres could have a further impact to guarantee access to new techniques for all countries. Thus agriculture could finally become a major pillar in a fair world order. 相似文献

以植物叶蛋白浓缩物为材料,用胰蛋白酶在不同条件下对其进行水解。结果表明,胰蛋白酶作用于植物叶蛋白,其最佳水解温度为４０℃;最佳水解ｐＨ值为９;水解程度随酶量和反应时间增加而增加;各种不同种类的植物叶蛋白在相同条件下被胰蛋白酶水解的程度基本一致,证明了植物叶蛋白易被动物体内蛋白酶分解。 相似文献

Equine amnionitis and fetal loss: The case definition for an unrecognised cause of abortion in mares
KH Todhunter NR Perkins RM Wylie C Chicken AJ Blishen DJ Racklyeft G Muscatello MC Wilson PL Adams JR Gilkerson WL Bryden AP Begg 《Australian veterinary journal》2009,87(1-2):35-38
A series of abortions occurred in mares in New South Wales during 2004 that involved similar and unusual findings on post mortem examination of aborted fetuses and fetal membranes. The term Equine Amnionitis and Fetal Loss (EAFL) was developed to describe the condition. This form of abortion had not been previously recognised in Australia. The pathology alone is not specific for EAFL and diagnosis requires demonstration of a combination of certain pathological and bacteriological features. The purpose of this paper is to describe patterns considered consistent with EAFL cases as a working case definition for use by veterinarians and veterinary pathologists in identifying future cases of EAFL. More detailed papers are in preparation to fully describe the epidemiological, histopathological, and microbiological aspects of EAFL. 相似文献

Powdery mildew is an important pathogen of barley in many barley-growing areas. To identify molecular markers for the resistance gene Mlg located on chromosome 4H, a cDNA-AFLP approach was carried out on near-isogenic lines. Based on the identification of a differentiating fragment of 37 bp, which turned out to be part of a nucleoside diphosphate kinase as estimated by blastn , a CAPS marker has been developed, which co-segregated with Mlg in a population of 738 F2 -plants. Due to its co-dominant inheritance, clear banding pattern and close linkage this marker is well suited for marker-based selection procedures. 相似文献

Resistance to western flower thrips in greenhouse cucumber: effect of leaf position and plant age on thrips reproduction 总被引：1，自引：0，他引：1

Three greenhouse cucumber (Cucumis sativus L.) accessions, previously selected for low levels of damage after infestation
with Frankliniella occidentalis (Pergande), were tested for resistance against F. occidentalis in a no-choice greenhouse experiment
at the mature plant stage. The three accessions showed a strong reduction in thrips damage compared to the susceptible control.
The effects of leaf position and plant age of the four cucumber accessions on the reproduction of F. occidentalis were determined
in a leaf disc assay. Leaf position had a significant effect on thrips reproduction, whereas plant age, within the test range,
had not. In general, reproduction was higher on young leaves. Reproduction as measured on leaf discs from certain leaf positions
was strongly correlated with resistance of mature plants in the greenhouse, and can therefore be used as a quick test to screen
cucumber accessions for resistance against thrips.

Elevated phosphate concentrations at Safaga and Quseir, Red Sea, Egyptian coast, wererelated to some ecological and nutritional aspects of the macro-alga Cystoseira myrica during1985. The results obtained were compared with those recorded for a non-polluted control site atGhardaqa. Chemical analysis of surface seawater samples revealed that the concentrations of dissolvedphosphate at Safaga and Quseir were 3 and 20 times as much as that at Ghardaqa, respectively.The standing crop of C. myrica showed two peaks in spring and autumn. Maximum biomass yield(491 g m-2) and number of individuals (127 m-2) of C. myrica were recorded in the spring at theGhardaqa site. Quseir C. myrica samples contained significantly higher protein-N, total-N andtotal-P values but lower carbohydrate values than the Safaga and Ghardaqa samples (LSD at 1%level). Tissue N:P molar ratios for C. myrica, Laurencia papillosa and Ulva lactuca collected fromGhardaqa ranged from 68-98, compared to 30-59 for the same species collected at thephosphorus polluted sites at Safaga and Quseir. The carbon levels and the C:N ratios of C. myricaexhibited no significant variations in the three studied sites. However, the C:P ratios of Ghardaqaplants were significantly higher than those of Safaga and Quseir. 相似文献
