Nanotechnology is the emerging development of the core information technology in the 1980s, and it has been widely used in life medicine, optoelectronics and other fields. Nanotechnology is effectively combined with parasitic disease reagents instrumentation, drug treatment, vaccine prevention and control, and has a comprehensive application in the nano-gold standard test strip test kit and equipment, nano-carrier targeted anthelmintic drugs, new nano-vaccine adjuvant of research and development, etc. It penetrates deeply into the medical field and is widely used in parasitology. With the starting point of the application of nanotechnology in parasitology, this paper focused on the pathogenic detection, anthelmintic drugs and vaccine adjuvants of parasitic diseases. The authors described the application of nano-technology, such as colloidal gold labeled immunoaffinity chromatography, microparticle material synthesis and biosensing, in the diagnosis and diagnosis of parasitic pathogens. The progress of new nano-insect repellent drug lipid carrier, chemical synthesis medicine and herbal medicine research and development had been discussed here, in addition to liposomes, polymer particles, and cytokines in vaccine adjuvants. This review could be expected as a reference for nanotechnology in in-depth research and better application in parasitology. 相似文献

近年来,中兽药在现代畜禽养殖、对抗动物疫病、调节改善动物免疫力方面都发挥了重要的作用,但是其在畜禽给药途径和生物利用度方面还存在一定不足。畜禽消化系统的不同导致给药方式必然存在不同,兽用中药配方颗粒使用方便,而且生物利用度高于中药散剂。目前尚无兽用中药配方颗粒的相关研究,本文对兽用中药配方颗粒的研究进展进行归纳总结,以期为兽用中药配方颗粒的开发利用提供依据。 相似文献

The understanding of heart failure is no longer based on a supply and demand model of pump failure. Rather, heart failure is seen as a complex pathophysiological process with activation of various neuroendocrine systems. The goals of treatment have changed towards modifying these counterproductive neuroendocrine systems and slowing myocardial maladaptation. Angiotensin converting enzyme inhibitors are the only licensed drugs in veterinary practice that have a direct effect on neurohormones in heart failure. The range of drug options in human medicine is greater and some of these drugs are also increasingly being used in veterinary cardiology practice. This review describes the neuroendocrine systems involved in heart failure and discusses the range of drugs available in human and veterinary medicine. In doing so, it concentrates on the evidence available from good quality randomised trials in both the veterinary field and, where relevant, the human medical field. 相似文献

This review provides a tutorial for individuals interested in quantitative veterinary pharmacology and toxicology and offers a basis for establishing guidelines for physiologically based pharmacokinetic (PBPK) model development and application in veterinary medicine. This is important as the application of PBPK modeling in veterinary medicine has evolved over the past two decades. PBPK models can be used to predict drug tissue residues and withdrawal times in food‐producing animals, to estimate chemical concentrations at the site of action and target organ toxicity to aid risk assessment of environmental contaminants and/or drugs in both domestic animals and wildlife, as well as to help design therapeutic regimens for veterinary drugs. This review provides a comprehensive summary of PBPK modeling principles, model development methodology, and the current applications in veterinary medicine, with a focus on predictions of drug tissue residues and withdrawal times in food‐producing animals. The advantages and disadvantages of PBPK modeling compared to other pharmacokinetic modeling approaches (i.e., classical compartmental/noncompartmental modeling, nonlinear mixed‐effects modeling, and interspecies allometric scaling) are further presented. The review finally discusses contemporary challenges and our perspectives on model documentation, evaluation criteria, quality improvement, and offers solutions to increase model acceptance and applications in veterinary pharmacology and toxicology. 相似文献
