Nonhuman primates are commonly used as experimental animals due to their biological resemblance to humans. In patients with cardiac disease, the levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) tend to increase in response to cardiac damage, and they are thus used as indicators for the diagnosis of human heart failure. However, no reference values for ANP and BNP have been reported for heart disease in nonhuman primates. In this study, we recorded the age, sex, and body weight of 202 cynomolgus monkeys, and performed evaluations to assess the ANP and BNP levels, electrocardiography and echocardiography, and accordingly divided the monkeys into two groups: healthy monkeys and those with spontaneous cardiac disease. Statistical analysis was performed to determine the relationship of ANP and BNP with the factors of age, sex, and body weight. No significant relationship was found between the levels of ANP and BNP and the factors of age, sex, and body weight. However, both the ANP and BNP levels were significantly different between the healthy monkeys and monkeys with valvular disease. Similar to humans, the ANP and BNP levels tended to increase with the progression of cardiac disease in monkeys. Based on these results, we concluded that ANP and BNP are indicators of cardiac disease in nonhuman primates, and that this nonhuman primate cardiac disease model is applicable for cardiology research in humans. 相似文献

为给猪细小病毒（Porcineparvovirus,PPV）主要非结构蛋白（NS1）基因选择良好的宿主表达系统提供参考依据,本研究运用EMBOSS在线分析软件的CHIPS和CUSP程序对PPVNS1基因进行密码子偏爱性分析。结果显示PPVNS1基因的CAI值为0．642,ENC值为39．703,这表明NS1在密码子使用上存在较明显的偏爱性,且第三位核苷酸尤其偏爱A或T;从与PPVNS1基因密码子使用频率比值上看,使用频率差异较大的在大肠杆菌有33个、酵母有26个、人有27个;PPVNS1基因共有71个大肠杆菌稀有密码子,并且还有多个稀有密码子多次串联成簇出现的情况。结果表明酵母等真核生物与其密码子偏爱性较为接近,可作为该基因体外表达宿主的首选。 相似文献

Infection and colonization with methicillin-resistant Staphylococcus aureus (MRSA) are now increasingly being reported in animals and people who work with animals, including horses and horse personnel. The objectives of this study were to evaluate the prevalence of MRSA colonization in veterinary personnel attending an international equine veterinary conference, and to identify risk factors for MRSA colonization in this group. Volunteers were recruited at the conference to provide a single nasal swab and complete a questionnaire regarding contact with the human health care system, contact with horses, and personal hand hygiene. Colonization with MRSA was found in 26/257 (10.1%) of study participants. Multivariable analysis showed an increased risk of MRSA colonization associated with having been diagnosed with or having treated a patient diagnosed with MRSA colonization or infection in the last year (odds ratio [OR] 8.41, 95% confidence interval [CI] 1.51–49.92, P = 0.015; OR 3.27, 95% CI 1.05–10.11, P = 0.039, respectively), whereas hand washing between infectious cases (OR 0.27, 95% CI 0.11–0.72, P = 0.009) and hand washing between farms (OR 0.35, 95% CI 0.14–0.98, P = 0.047) were protective. The prevalence of MRSA colonization among equine veterinary personnel found in this study was high compared to that of other studies of the general population. These data support previous suggestions that equine veterinary personnel are at increased risk of colonization with MRSA. This is the first study to demonstrate a statistically significant association between hand hygiene practices and a measurable clinical outcome in veterinary medicine. 相似文献

2007年8月,福州动物园1只25岁,体重150 kg的雄性(阉割)猩猩突然发病,出现口唇歪斜、半身不遂等症状。实验室检查结果表明血液和尿液常规指标,肾肝功能的生化指标等均未见异常。凝血酶原时间和活化部分凝血酶时间均缩短,纤维蛋白原浓度升高,提示了患病猩猩的血液处于高凝状态或有血栓形成,并且血液粘稠度高。经过静脉注射重组人组织型纤溶酶原激活剂溶解血栓,依达拉奉保护脑神经,甘露醇控制脑水肿;皮下注射低分子肝素钠和辅助治疗。15 d后,患病猩猩症状缓解并逐渐康复。根据患病猩猩的临床症状,实验室检查和治疗效果的分析,我们认为患病猩猩疑似脑血栓形成。 相似文献
