目前的国家兽药质量标准中,对西药的复方制剂收载较少。中华痢星注射液为我区某厂生产的一种西药复方制剂,根据使用说明,主要成份含痢菌净和喹乙醇,规格为:10毫升含喹乙醇400毫克、痢菌净200毫克。两者的单方制剂,国家质量标准是用分光光度法测定含量。两者复方制剂的含量测定,未见有报道。因痢菌净和喹乙醇的吸收峰相似,配成复方制剂后不能直接用分光光度法测定。笔者根据痢菌净溶于氯仿、喹乙醇几乎不溶于氯仿的特性,用氯仿提取痢菌净,把两者分离,再分别测定含量。实验表明,方法可靠,操作简单,不需添贵重仪器,便于药品的定量检测。1 仪器… 相似文献

通过了解痢菌净在不同溶剂及助溶剂的溶解情况,筛选并组合最佳溶剂,以制备高含量痢菌净溶液,为临床药剂开发提供参考依据。运用全波长扫描选取最适痢菌净检测波长,并建立痢菌净含量检测方法,测定不同溶剂及助溶剂对痢菌净的最大溶解量,组合形成可溶解高含量痢菌净溶液的混合溶剂。结果表明,痢菌净在373.0 nm、368.0nm、356.0 nm、254.0 nm、241.0 nm均有吸收峰,经与其他所选溶剂及助溶剂全波长扫描图谱比较,选取373为最适检测吸收波长。建立的痢菌净含量检测方法在1.25~20μg/m L浓度范围内,吸收度与浓度呈良好的线性关系,R2=0.9992。不同溶剂及助溶剂中,单一溶剂或助溶剂对痢菌净的溶解程度均较混合溶剂差,且以水杨酸钠效果最好,但其在350.0~500.0 nm区间有较低的吸收峰,对运用紫外分光光度法测定痢菌净含量有一定的影响,2种混合溶剂均有较好的溶解效果,混合溶剂1溶解量最大,达54.37 mg/m L。为以后痢菌净缓释药剂的开发奠定了基础。 相似文献

A simple method to determine the beta-blocker carazolol in swine kidneys is presented. Spiked samples, homogenised under alkaline conditions, were heated. Passage of the ether extracts through C18 and silica Sep-Pak cartridges yielded a fraction containing the carazolol in 88% recovery. In this fraction carazolol was determined by fluorescence spectrophotometry. By this method a level of 1 microgram/kg in spiked samples can be detected. Injection of 10 micrograms/kg body weight, 105 minutes before slaughter, resulted in carazolol contents in kidneys ranging from 11 to 25 micrograms/kg (n = 8). 相似文献

A minimally invasive method for delivering injectable therapeutic agents would be desirable for the treatment of intervertebral disc disease in dogs. The purpose of this study was to compare computed tomography (CT), ultrasonography (US), and fluoroscopy modalities for guiding percutaneous injection into canine intervertebral discs. Intervertebral discs of 14 dog cadavers were injected with a gelified ethanol therapeutic agent. Successful injectate placement and injectate leakage were determined based on necropsy inspection of discs. Injection into the nucleus pulposus was successful in 55 of 78 (71%) of all injected discs. Injections guided using CT and fluoroscopy were significantly more successful than US‐guided injections. Odds of successful injection without leakage were greater for CT vs. US (P = 0.0026) but there was no significant difference between CT and fluoroscopy (P = 0.0620). Injection success rates did not differ among vertebral sites or dog cadavers of varying weights. Forty‐nine (63%) of injection sites had injectate leakage outside the disc and 10 of these involved structures within the vertebral canal. The highest rate of injection success with the least amount of leakage was achieved with CT guidance. Findings indicated that CT, fluoroscopy, and US are feasible modalities for guiding percutaneous injection of a gelified ethanol therapeutic agent into the canine intervertebral disc, with moderate to high success rates for different regions of the spine. However, a moderately high rate of injectate leakage occurred outside of the disc and this should be taken into consideration for future safety and efficacy studies. 相似文献

Pork is traditionally low in docosahexanoic acid(DHA, C22:6n-3) and deficient in omega-3 fats for a balanced human diet. DHA as triglycerides was commercially prepared from the microalgae Schizochytrium and injected into fresh pork loins. Treatments of a mixed brine control(CON), 3.1% sunflower oil in mixed brine(SF) and a 3.1% DHA oil in mixed brine(DHA) were injected into pork loins at 10 mL/100 g and grilled at 205°C. After cooking, the CON and SF pork loins contained 0.03 to 0.05 mg DHA/g of pork and the DHA injected loins contained approximately1.46 mg DHA/g. This also changed the fatty acid profile of omega-6: omega-3 from, 5 to 1 in the CON pork, to a ratio of 1.7 to 1 in DHA pork. The appearance, odor, oxidation rates and sensory taste, as judged by a trained panel,determined the DHA injected meat to be, ‘slightly desirable' and gave lower ‘off flavour' scores, relative to the CON and SF injected pork. Pork can be fortified with DHA oil to 146 mg/100 g serving, which would meet half the recommended daily omega 3 fatty acid requirements for adult humans and would be desirable in taste. 相似文献
