[Methods] The samples were extracted with 80% acetonitrile water(containing 0.1% formic acid), combined with QuEChERS extraction technology and C18 and PSA purification, analyzed by high performance liquid chromatography-mass spectrometry, and quantified by external standard method. The target substances were analyzed on ZORBAX Eclipse C18 chromatographic column using 0.2% formic acid water and 0.2% methanol as mobile phases. The gradient elution mode was used for chromatographic separation and multiple reaction detection. [Results] In the linear range of 0.5-50.0 ng/ml, the linear relationship of the 54 kinds of veterinary drug residues was good, with correlation coefficients(r~2) greater than 0.995, and the detection limits ranged from 0.30 to 1.00 μg/kg. The results showed that the recovery ranged from 75.4% to 118.2% when different matrixes were added for recovery. [Conclusions] This method is simple, efficient, accurate, stable, and highly operable. It is applicable to simultaneous batch screening of veterinary drug residues in animal-derived food, and has high practical application value.展开更多

Previous studies have identified a significant increase in infections with S. pseudintermedius. Samples were taken from the hospital environment by swabbing areas in the intensive care unit and anesthesia preparation room and bacterial species identified. Isolates obtained from patients were then examined regarding the ability to form biofilm, an important phenotype on hospital-related infection. In addition, veterinary hospital associated strains of S. pseudintermedius were used to determine the bactericidal effect of the used disinfectant, applying the hospital current protocol, by comparing the efficacy against S. pseudintermediius and a strain of Staphylococcus aureus from a dog. The isolates identified were resistant to commonly used antibiotics such as enrofloxacin and cephalosporins, and 45% percent of those were methicillin resistant. The environmental survey in the hospital identified S. pseudintermedius in the pre-anesthesia area, although the isolate was killed by the current used disinfection protocol. A few disease associated bacteria were evaluated for biofilm formation in comparison to a dog isolate of Staphylococcus aureus, demonstrating strong ability to form biofilms.展开更多

Three aspects are considered in the development of education in animal welfare （AW）： （1） introduction of AW in curricular education, nevertheless it has not been applied in the Facultad de Veterinaria, Universidad de la Repfiblica de Uruguay, up to now; （2） promotion of permanent education for graduates; （3） development of plans for dissemination, follow up, assessment and continuous improvement on AW affairs. Aiming to obtain information about the knowledge of veterinarians on AW during the practice of their professional duties, in September 2016, an on-line questionnaire was sent to the veterinarians who were in the Educaci6n Continua database. The questionnaire had four sections： a general gathering information and three additional sections, one for each veterinarian professional field （large animal＇s health and production, small animal＇s health and food industry）. From 1,804 questionnaires sent, 388 answers were obtained. There were 69% attended at least one AW course, and 89.9% were willing to attend another AW course. And 63.5% considered the information received to be very useful for their daily activities, 95% considered that AW should be included in the veterinary studies curriculum, while 53.3% declared not having knowledge about the regional animal welfare strategy （RAWS）. The majority of the veterinarians considered the acquired knowledge very useful and are eager to obtain more information. It is necessary to keep working to include AW in the veterinary studies curriculum as well as continuing with the diffusion of good practices and AW principles, based on the national and international norms.展开更多

These assays are important because of their superior ability to forecast fertility when compared with other tests, such as sperm motility. This major component of the sperm quality assessment has generated new investigations with the aim of developing tests that can detect membrane damage in a very early state. Using phospholipid transposition tests, early changes in membrane permeability and fluidity can be assessed in a large number of spermatozoa using fluorescent probes in combination with flow cytometry.展开更多

Achieving high pa...For veterinary medications administered per os, animal health companies strive to develop highly palatable dosage forms that are voluntarily accepted by animals to improve compliance and convenience. Achieving high palatability is often complex and difficult even without the presence of an active ingredient. This work compared acceptance and preference studies, as standardized methods are not established for informing formulation development or for more routine testing. Formulation development was followed by an acceptance study completed with laboratory Beagle dogs. One acceptance study and one preference study were completed in mixed breed dogs, also laboratory-housed, to gain wider representation of dog breed and age. Through these studies, we have evaluated both formulation parameters and palatability study conduct. In general, more complex palatants that have appealing taste, smell, and mouth feel enhance voluntary uptake. However, dosage forms that are too chewy may not be freely consumed even with complex palatants. The addition of aroma can entice dogs to prehend the tablet, as observed in one preference study. Preference studies in the veterinary pharmaceutical field identify the preferred first choice or first prehend, but not which product will be routinely voluntarily and fully consumed. Acceptance studies with cross-over treatment groups are used to quantify the full consumption of a dosage form when a dog is not given two choices at once. Since all dogs in acceptance studies are offered all treatment groups throughout the study, a comparison between degrees of consumption could suggest that one formulation might be preferred over another.展开更多

Three aspects are considered in the development of education in animal welfare （AW）： （1） introduction of AW in curricular education, nevertheless it has not been applied in the Facultad de Veterinaria, Universidad de la Repfiblica de Uruguay, up to now; （2） promotion of permanent education for graduates; （3） development of plans for dissemination, follow up, assessment and continuous improvement on AW affairs. Aiming to obtain information about the knowledge of veterinarians on AW during the practice of their professional duties, in September 2016, an on-line questionnaire was sent to the veterinarians who were in the Educaci6n Continua database. The questionnaire had four sections： a general gathering information and three additional sections, one for each veterinarian professional field （large animal＇s health and production, small animal＇s health and food industry）. From 1,804 questionnaires sent, 388 answers were obtained. There were 69% attended at least one AW course, and 89.9% were willing to attend another AW course. And 63.5% considered the information received to be very useful for their daily activities, 95% considered that AW should be included in the veterinary studies curriculum, while 53.3% declared not having knowledge about the regional animal welfare strategy （RAWS）. The majority of the veterinarians considered the acquired knowledge very useful and are eager to obtain more information. It is necessary to keep working to include AW in the veterinary studies curriculum as well as continuing with the diffusion of good practices and AW principles, based on the national and international norms.
文摘Artemisinin,a constituent of Artemisia annua L.,is a well-known antimalarial drug.Artemisinin-type drugs also inhibit cancer growth in vitro and in vivo.Herbal extracts of A.annua inhibit the growth of cancer cell lines.Here,we report on the use of capsules containing powder of Herba Artemisiae annuae to treat pet sarcoma.The surgical tumor removal as standard treatment was supplemented by adjuvant therapy with A.annua.One cat and one dog with fibrosarcoma survived 40 and 37 months,respectively,without tumor relapse.Two other dogs suffering from fibrosarcoma and hemangioendothelial sarcoma also showed complete remission and are still alive after 39 and 26 months,respectively.A.annua was well tolerated without noticeable side effects.These four cases indicate that A.annua may be a promising herbal drug for cancer therapy.

文摘As an important guarantee for the prevention and control of animal diseases,veterinary drugs have important functions in improving animal production performance and product quality and maintaining ecological balance.They are an important guarantee for the healthy development of animal husbandry,food safety and public health.However,the irrational use and abuse of veterinary drugs and feed pharmaceutical additives are widespread,causing harmful substances in animal foods and damage to human health,and threatening the sustainable development of the environment and animal husbandry as well.In order to ensure human health,it is urgent to develop a simple,rapid,high-sensitivity,high-throughput and low-cost veterinary drug residue detection technology.In this paper,the sample pretreatment methods and detection techniques for the analysis of veterinary drug residues in animal foods were reviewed.
文摘Thanks to the increasing use of flow cytometry in research in veterinary spermatology, many new membrane integrity assays have been developed over the past decade. These assays are important because of their superior ability to forecast fertility when compared with other tests, such as sperm motility. This major component of the sperm quality assessment has generated new investigations with the aim of developing tests that can detect membrane damage in a very early state. Using phospholipid transposition tests, early changes in membrane permeability and fluidity can be assessed in a large number of spermatozoa using fluorescent probes in combination with flow cytometry.
文摘For veterinary medications administered per os, animal health companies strive to develop highly palatable dosage forms that are voluntarily accepted by animals to improve compliance and convenience. Achieving high palatability is often complex and difficult even without the presence of an active ingredient. This work compared acceptance and preference studies, as standardized methods are not established for informing formulation development or for more routine testing. Formulation development was followed by an acceptance study completed with laboratory Beagle dogs. One acceptance study and one preference study were completed in mixed breed dogs, also laboratory-housed, to gain wider representation of dog breed and age. Through these studies, we have evaluated both formulation parameters and palatability study conduct. In general, more complex palatants that have appealing taste, smell, and mouth feel enhance voluntary uptake. However, dosage forms that are too chewy may not be freely consumed even with complex palatants. The addition of aroma can entice dogs to prehend the tablet, as observed in one preference study. Preference studies in the veterinary pharmaceutical field identify the preferred first choice or first prehend, but not which product will be routinely voluntarily and fully consumed. Acceptance studies with cross-over treatment groups are used to quantify the full consumption of a dosage form when a dog is not given two choices at once. Since all dogs in acceptance studies are offered all treatment groups throughout the study, a comparison between degrees of consumption could suggest that one formulation might be preferred over another.
文摘Thousands of tons of pharmaceutically active substances are used in veterinary medicines in intensive livestock and poultry production, but most of the drugs are poorly absorbed by animals and excreted with the animal feces. The veterinary medicines can cause various kinds of harmful impact to the environment. Now the relevant research has been a hot all over the world. With the feces excreted to the environment, the veterinary medicines can be accumulated in the soil and water, and produce all sorts of reaction. Some medicines can cause toxic effect to animals, plants and microorganisms. The article summarized the residue, the environmental impact, the transformation and the development direction of the veterinary medicine in the environment to supply frame of reference for further research.

文摘This study was conducted to investigate the effects of extracts of 4 Tibetan veterinary drugs on bacterial diarrhea, and to guide the clinical treatment of the disease. The inhibitory effects of the extracts of the 4 Tibetan veterinary drugs, Veronica ciliate Fisch, Usnea diffracta Vain, Sophoraflavescens var. flavescens, Lamiophlomis rotata （ Benth. ） Kudo on 14 common diarrheagenic bacteria were detected by K-B diffusion method and micro-broth dilution method. Optimization was performed on prescriptions of the 4 Tibetan veterinary drugs using orthogonal design software, and a mouse bacterial diarrhea model was established with a clinical isolate, Salmonella blegdam. According to the LD50 value of the optimal prescription of the 4 Tibetan veterinary drugs, the established mouse bacterial diarrhea model was treated in 3 dose groups, i. e. , the high, middle and low dose groups （0. 060, 0. 030 and 0. 020 g/ml, respectively）. The results showed that the 4 Tibetan veterinary drugs had very good inhibitory effects on most of the tested diarrheagenic bacteria, and among them, U. diffracta had better inhibitory effects on all the tested bacteria. The optimal prescription of the d Tibetan veterinary drugs （high dose, 0.06 g/ml） exhibited very good inhibitory effect on mouse diarrhea, indicating that the prescription has very good anti-diarrhea effect, which is beneficial to the clinical treatment of such disease and the development of Tibetan veterinary drugs.
