碘酊是兽医临床上一种常用外用消毒药,所以碘酊的配制是我们兽医工作者应掌握的普通知识,而在兽医生产实践中所配制应用的部分碘酊不合乎要求,可以看到碘酊中的碘片没有完全溶解,直到碘酊快用完还保留着大量的碘片结晶沉淀物,因而影响到碘酊的有效杀菌作用。现将配制... 相似文献

不同原料配置成的稀释粉对公猪精液品质的影响极为重要,选择合适的原料配置成的稀释粉不仅可以节约成本,还可以简化配制操作过程。柠檬酸是无色结晶或白色结晶状颗粒(乙级品略带黄色);无臭、味极酸;易溶于水和乙醇;微溶于乙醚;水溶液呈酸性反应。在多次配制稀释粉的过程中我们发现,由于柠檬酸吸水性较强,在研磨过40目筛很容易黏结。为减少研磨损失及其所带来的误差,方便快捷的配制稀释粉。 相似文献

Including Baytril, in various parts of the world many commercial preparations of enrofloxacin for parenteral administration are being employed for the treatment of bacterial diseases in cows. To optimize clinical responses and to minimize development of bacterial resistance to this agent, the copied pharmaceutical preparations must comply with some key pharmacokinetic features when bioequivalence studies are performed. To assess whether or not there was bioequivalence among nine commercial preparations of enrofloxacin and the original one, a controlled pharmacokinetic study was carried out. These was done utilizing the microbiological agar-diffusion test as quantitative/qualitative analytical method. A non-compartmental model defined kinetic variables. Results for Baytril revealed that maximal serum concentration (Csmax) was only matched by one preparation while area under the curve (AUC) of the serum concentration/activity of enrofloxacin and metabolites in time was not matched by any preparation. Time to Csmax (Tmax), elimination half-life, and shape of the time-serum concentrations of enrofloxacin profiles obtained for the nine generic preparations differ significantly somehow from the corresponding data obtained for the reference enrofloxacin. The need for studies to demonstrate bioequivalence becomes mandatory if similar preparations of enrofloxacin become commercially available. Enrofloxacin should be used selectively and cautiously to limit development of bacterial resistance. Non-bioequivalence of relevant pharmacokinetic values, such as Csmax and bioavailability (AUC) would facilitate development of bacterial resistance and limit the useful life span of this antibacterial agent. 相似文献

Four different treatments of bovine ketosis, using 3 different pharmaceutical preparations, were monitored. The main antiketogenic and glucogenic ingredients of the preparations were as follows: invert sugar (Metabol), prednisolone and dexamethasone (Predasen), the former preparations combined (Metabol & Predasen) and propylene glycol and dexamethasone (Dexaprol). Blood samples were drained from the ketotic cows prior to the treatment. The animals were sampled again 2 and 7 days after the first sampling. The whole blood concentrations of acetoacetate (AA concn), β-hydroxybutyrate (BHB concn) and glucose (glue concn) were determined. The measures of the antiketogenic and glucogenic efficacy of the various treatments applied were their ability to reduce the AA concn and BHB concn and to elevate the gluc concn.Invert sugar (Metabol) alone had no antiketogenic efficacy, although in some cases it led to a subjective clinical improvement as reported by the owners of the animals. Invert sugar and glucocorticoids (Metabol & Predasen) dexamethasone and prednisolone (Predasen) and dexamethason plus propylene glycol (Dexaprol) were equally effective in bringing the AA, BHB and glue concns to normal range. The mean glue concn of the cows treated with Dexaprol was higher than that of the cows in the other treatment groups at 2 days (P < 0.01). No other differences between the 3 antiketogenic treatments could be shown. 相似文献

The commercial use of sheep for the production of milk and milk products is attractive to farmers actively diversifying their dairy interests due to the impact of the quota system. As intensification of milking increases, flock sizes will enlarge and the incidence of ovine mastitis will inevitably increase. The pharmaceutical industry and the veterinary practitioner will be required to provide advice and data upon the performance of currently available bovine intramammary preparations for the sheep. This study produces evidence to confirm that one available bovine intramammary preparation, when infused into milking sheep, produced a withholding time approximately three times as long as that defined for the cow. Following a course of three infusions over a period of 24 hours after consecutive milkings, milk was not acceptable for human consumption or for the production of cheese and yoghurts until 136 hours following the final infusion. This situation is likely to be representative of that which will occur with other intramammary products used in the ovine species following infusion with bovine intramammary preparations. 相似文献

Ivermectin (IVM) is a broad-spectrum antiparasitic drug extensively used in veterinary medicine. The composition of the pharmaceutical preparation affects IVM absorption and its systemic availability. After the introduction of the first approved IVM formulation (propylene glycol/glycerol formal 60:40) used at 200 microg/kg, different pharmaceutical modifications have been assayed to extend IVM persistent endectocide activity. Recently, IVM 3.15% long-acting (IVM-LA) preparations to be administered at 630 microg/kg to cattle were introduced into the veterinary pharmaceutical market. The work reported here was designed to evaluate the comparative IVM absorption pattern and plasma concentration profiles obtained after subcutaneous administration of the classic pioneer IVM formulation (1%) and two different commercially available IVM-LA preparations (3.15%) to cattle. Twenty-eight Holstein heifers were divided in four experimental groups (n=7) and treated subcutaneously as follows--Group A: IVM 1% given at 200 microg/kg, Group B: IVM 1% administered at 630 microg/kg, Group C: IVM-LA (A) injected at 630 microg/kg and Group D: IVM-LA (B) given at 630 microg/kg. Blood samples were taken between 0.5 and 90 days post-treatment and IVM plasma concentrations were determined by HPLC with fluorescence detection. There were no differences in the persistence of IVM plasma concentrations after the administration of IVM 1% formulation at the two used dose levels (200 and 630 microg/kg). Higher peak plasma concentration (C(max)) and shorter mean residence time (MRT) were obtained for IVM 1% given at 630 microg/kg (Group B) compared to the treatments with both IVM-LA preparations. The IVM-LA (A) formulation showed a more extended absorption process than IVM-LA (B) preparation, which accounted for a longer persistence of detectable IVM plasma concentrations. The parasitological implications of the observed differences in peak plasma concentrations (C(max) values) and in the IVM concentration levels measured from day 20, and afterwards until day 90 post-treatment, between the different preparations assayed need to be elucidated. The characterization of the absorption patterns and kinetic behaviour obtained after injection of these novel long-acting formulations used at three times the therapeutic dose recommended for the classic IVM preparation in cattle is a further contribution to the field. 相似文献

医院药学人才培养导向的《药理学》教学改革探索 《畜牧与饲料科学》2014,35(3):44-44
《药理学》是医药院校临床与基础专业的重要必修课之一,其课程教学内容主要包括药物的作用、作用机制、药物的临床应用和药物的不良反应等。医院药学人才培养导向主要是地方本科院校针对医院药剂科及药学相关部门科室培养的药学人才,该类人才不同于高端研发型药学人才,要求其具有丰富而又实用的药学基本知识和药品检验等基本技能,能熟练适应于医院工作条件。医院药学导向的人才培养也是应用型人才的一类,就该类人才导向的药理学教学改革进行了探讨。 相似文献

In 2010, three new active pharmaceutical ingredients were released on the German market for horses and food-producing animals. These were gamithromycin (Zactran?), a new macrolide antibiotic, Monepantel (Zolvix?), a broad spectrum anthelmintic with a novel mechanism, and Pergolide (Prascend?), the first dopamine receptor agonist for animals. Two substances have been approved for additional species. The tetracycline antibiotic doxycycline is now also authorized for turkeys and the nonsteroidal anti-inflammatory drug firocoxib from the group of cyclo-oxygenase-2 (COX-2) inhibitors is now available for horses. Furthermore, four new preparations with an interesting new pharmaceutical form, one drug with a new formulation and two drugs, which are interesting because of other criteria, were added to the market for horses and food producing animals. 相似文献
