实验动物采血方法 总被引：4，自引：0，他引：4
实验研究中，经常要采集实验动物的血液进行常规检查或某些生物化学分析，故必须掌握血液的正确采集、分离和保存的操作技术。采血方法的选择，主要决定于实验的目的所需血量以及动物种类。凡用血量较少的检验如红、白细胞计数、血红蛋白的测定、血液涂片以及酶活性微量分析法等，可刺破组织取毛细血管的血。当需血量较多时可作静脉采血。静脉采血时，若需反复多次，应自远离心脏端开始，以免发生栓塞而影响整条静脉。例如，研究毒物对肺功能的影响、血液酸碱平衡、水盐代谢紊乱，需要比较动脉血氧分压、二氧化碳分压和血液pH值以及K^＋、Na^＋、Cl^-离子浓度，必须采取动脉血液。 相似文献

1热应激对鸡只的危害
干扰鸡只的正常生理功能。热应激可使鸡的心跳速率增加，血压下降，呼吸加快，喘息，严重时可出现呼吸性碱中毒，血液pH值上升，血钠升高，血钾下降，钠钾比例失调（可促使心脏兴奋性增强），血液中葡萄糖、总蛋白质、球蛋白及白蛋白浓度均降低。 相似文献

动脉血压是指血液在动脉管内流动时对血管壁的压力,是由于每次心室收缩所产生的推动血液前进的力量和血液流经动脉时所遇到的外周阻力,这两种相反的力量互相作用形成的。测量血压的变化,在临床上有着重要的意义,可对疾病的临床诊断、护理及预后提供可靠的依据,在医学界已得到广泛应用。但不同方法、畜种及部位所测的结果不一样,因而应建立不同方法、畜种的正常值。目前在兽医上,只建立了部分家畜的血压正常值。骡 相似文献

为了研究在不同季节各月龄阶段安格斯牛的血液生理与生化指标变化,了解安格斯牛在新疆石河子地区的适应性,该试验分别于冬夏两季,在初生、10月龄、18月龄3个阶段各随机选取50头牛,分别于颈静脉与尾静脉采血进行生理生化指标分析。结果表明:初生阶段,总蛋白含量、血糖浓度、白细胞总数和红细胞数量在冬夏两季差异显著(P<0.05);10月龄阶段,甘油三酯浓度、尿素氮浓度、红细胞数量与白细胞总数在冬夏两季差异显著(P<0.05);18月龄阶段,甘油三酯浓度与白细胞总数在冬夏两季有显著差异(P<0.05);其余指标差异均不显著。安格斯牛对不同气候有相对较好的适应性,但夏季高温可能会影响安格斯牛的生产性能。 相似文献

本试验通过研究吉林梅花鹿不同生长阶段血液生理生化指标的差异情况,旨在为梅花鹿的健康检测、疾病防治、育种等提供依据和参考。选取吉林省左家、双阳、东丰地区哺乳仔鹿93头（公37头,母56头）、育成鹿135头（公40头,母95头）、成年鹿130头（公42头,母88头）,共358头,进行13项血液生理指标、19项生化指标检测。结果显示：哺乳公鹿与哺乳母鹿各项指标总体上差异不大,仅红细胞系统指标、血糖、肌酸激酶具有显著性差异（P<0.05）;红细胞压积、红细胞平均体积、平均血红蛋白含量、平均血红蛋白浓度、碱性磷酸酶、乳酸脱氢酶在不同性别的育成鹿与成年鹿中差异极显著（P<0.01）。不同生长阶段公鹿天门冬氨酸氨基转移酶、前白蛋白、总胆汁酸、血糖等差异显著（P<0.05）,红细胞系统、肌酸激酶、钙、无机磷、肌酐等差异极显著（P<0.01）,白蛋白、淀粉酶差异不显著（P>0.05）;不同生长阶段的母鹿淋巴细胞总数、红细胞总数、中性粒细胞总数差异显著（P<0.05）,白细胞总数、红细胞系统指标、天门冬氨酸氨基转移酶、丙氨酸氨基转移酶、肌酸激酶、钙、无机磷等差异极显著（P<0.01）,谷氨酰转肽酶、总胆汁酸、白蛋白差异不显著（P>0.05）。以上结果说明,不同生长阶段、不同性别的梅花鹿血液生理生化指标存在较大变异,部分指标的差异可能与梅花鹿生茸、性别等生物学特性有关。对上述生理生化指标的测定,获得了不同性别的梅花鹿在不同生长阶段生理生化指标的参考范围,可为梅花鹿选种育种、疾病诊断、资源开发利用提供一定的参考,也可为野生东北梅花鹿资源保护和健康评估提供依据。 相似文献

This experiment was conducted to investigate the effect of feeding phytoestrogens on milk composition, blood biochemical index and antioxidant capacity of dairy cows.A total of 40 Holstein cows were selected and randomly divided into 4 groups by health, age and lactation stage. The cows in control group was fed total mixed rations(TMR), and the other in 3 trial groups were fed TMR supplemented with 2.5 g dainzein(group Ⅰ), 35 g formononetin (group Ⅱ), 1.25 g dainzein and 17.5 g formononetin (group Ⅲ), respectively. The total duration of the trial was 127 d, the first 7 d of the trial was the preliminary period and the formal trial lasted for 120 d. The milk samples were collected in the trial of 0, 30, 60, 90, 120 d, respectively, and determination of milk composition. The blood samples were collected by jugular vein in the trial, and plasma was separated by 15 min, 3 500 r/min centrifugation, and saved at －20 ℃ for later use. The result showed as follows: Compared with the control group, the milk yield and milk protein yield in groups Ⅰ and Ⅲ were significantly increased (P< 0.05),the lactose yield in groups Ⅰ,Ⅱ and Ⅲ were significantly increased (P< 0.05), the T-AOC activity of blood in group Ⅲ was significantly increased (P< 0.05), the GSH-Px activity of blood in groups Ⅱ and Ⅲ were significantly increased (P< 0.05), the MDA activity of blood in groups Ⅰ and Ⅱ were significantly decreased (P< 0.05), the milk fat yield,lactose rate and TP, ALB, GLB of blood were not significantly increased (P> 0.05),the CAT, SOD activity of blood in trail groups had a upward trent. It was concluded that feeding phytoestrogens could enhance the milk yield, milk protein yield, lactose yield, the body's antioxidant capacity and immune function of Holstein cows. 相似文献

OBJECTIVE: To determine the effects of intravenous (IV) butorphanol on the cardiopulmonary system and on the bispectral index (BIS) in isoflurane-anesthetized alpacas. STUDY DESIGN: Randomized, blinded cross-over experimental trial. ANIMALS: Eight healthy, young (3 +/- 1 SD years) adult female alpacas weighing 64 +/- 9 SD kg. METHODS: Alpacas were anesthetized with isoflurane by mask followed by tracheal intubation and maintenance of anesthesia with isoflurane in oxygen and intermittent positive pressure ventilation. Animals were assigned to two treatments, butorphanol (0.1 mg kg(-1), IV) and saline (0.01 mL kg(-1), IV) in a randomized manner allowing a 2-week interval between treatments. Cardiovascular variables included systolic, diastolic, and mean arterial blood pressure, heart rate, pulmonary arterial pressure, pulmonary arterial occlusion pressure (PAOP), central venous pressure, cardiac output, and pulmonary temperature (TEMP). Cardiac index, systemic vascular resistance (SVR), and pulmonary vascular resistance (PVR) were calculated. Bispectral index was also measured. Arterial and mixed venous blood samples were collected for blood gas analysis. All variables were recorded at baseline (time 0) and at 5, 10, 15, 30, 45 and 60 minutes following injection and were analyzed by using repeated-measures ANOVA (p < 0.05). PAOP, PVR, and BIS were analyzed by paired t-tests. RESULTS: Butorphanol decreased SVR at all times when compared with the baseline, but no difference was detected between treatments. TEMP decreased with time in both treatments, but they were not different from each other. Other cardiovascular, BIS, and blood gas variables were not different between groups. CONCLUSION AND CLINICAL RELEVANCE: We conclude that butorphanol had minimal effects on the cardiovascular system of the alpacas, causing a mild decrease in SVR. 相似文献

OBJECTIVE: To compare blood glucose (BG) concentrations measured with a portable blood glucose meter in blood samples obtained with a marginal ear vein (MEV) nick technique, from a peripheral venous catheter, and by direct venipuncture in healthy cats and cats with diabetes mellitus. DESIGN: Prospective study. ANIMALS: 1 0 healthy cats and 11 cats with diabetes mellitus. Procedure-On day 1, blood samples were collected every hour for 10 hours by the MEV nick technique and from a peripheral venous catheter. On day 2, blood samples were collected every hour for 10 hours by the MEV nick technique and by direct venipuncture of the medial saphenous vein. RESULTS: For all cats, mean BG concentration for samples collected by the MEV nick technique was not significantly different from mean concentration for samples obtained from the peripheral venous catheter. For healthy cats, mean BG concentration for samples collected by the MEV nick technique was not significantly different from mean concentration for samples obtained by direct venipuncture. For cats with diabetes mellitus, mean BG concentration for samples collected by the MEV nick technique was significantly different from mean concentration for samples obtained by direct venipuncture; however, for the range of concentrations examined, this difference was not clinically important. Conclusions and Clinical Relevance: Results suggest that for the range of concentrations examined, the MEV nick technique is a reasonable alternative to venous blood collection for serial measurement of BG concentrations in cats. 相似文献

Viral isolation, polymerase chain reaction (PCR), dot blot hybridization (DBH), and indirect enzyme-linked immunosorbent assay
(iELISA) were used for the diagnosis of lumpy skin disease in clinically infected, fevered, and apparently normal dairy cows.
Lumpy skin disease virus (LSDV) was isolated from skin biopsies and blood samples collected from clinically infected cows
in percentages of 72% and 20%, respectively. The virus recovered from blood samples collected from fevered cows in percentage
of 33.3%. Both PCR and DBH detected viral DNA in 100% of skin biopsies collected from clinically infected cows whereas the
detection rates in blood samples collected from clinically infected animals were 100% and 84% using PCR and DBH, respectively.
Viral DNA was detected in blood samples collected from fevered cows using PCR and DBH in percentages of 77.8% and 66.6%, respectively.
Only 19.1% of blood samples collected from in-contact cows was positive for both of PCR and DBH. Detection rates of antibodies
against LSDV using iELISA in serum samples collected from clinically infected and fevered cows were 56% and 11.1%, respectively,
whereas all in-contact cows had no antibodies against the virus. 相似文献

Blood gas values were compared in blood collected from cut toenails and femoral arteries in 50 healthy crossbred dogs that were sedated and allowed to breathe room air spontaneously. Blood samples from cut toenails were collected by microcapillary technique with Natelson tubes. Femoral artery samples were collected by arterial puncture. Blood values for PO2, PCO2, pH, and HCO3 were compared. There was good correlation for pH, PCO2, and bicarbonate, but not for PO2. Microcapillary samples should be collected in 10 seconds or less for the most accurate results. A metal mixing "flea" was unnecessary. When properly handled, the Natelson tube technique provides an alternative method for collection of blood gas samples. 相似文献
