肠阻塞骡不同舌色的载体血液黏度和微循环功能的变化 总被引：1，自引：0，他引：1
研究采用无创伤性方法测定了45匹健康骡和130例肠阻塞病骡不同病理舌色的载体血液黏度和微循环的功能指标，结果表明：暗红、青紫、赤红和红这4种病理舌色的载体血液黏度均高于正常组（P＜0.01），正常组和淡红舌组之间差异不显著（P＞0.05），而且随着舌色由淡红→红→赤红→暗红→青紫的发展，血液黏度也逐步升高，MRT、MST也逐步升高，MHR则正好相反。这一结果说明血液流变学性的变化和微循环功能的改变对舌色的形成机理具有意义。 相似文献

研究利用人工气候仓模拟热应激环境,建立热应激仔猪模型。试验以64头2月龄中国试验用小型猪为研究对象,将其随机分为对照组、高温应激组、中草药复方提取物工治疗组和中草药复方提取物Ⅱ治疗组,通过Wintrobe测试分析红细胞压积,同时采用血液流变自动分析系统分析全血黏度等血液流变学参数,以期研究中草药复合提取物对热应激仔猪血液流变学指标影响的动态变化。结果显示：应激组仔猪全血黏度高切变率值在第10天显著高于对照组（P〈0．05）,红细胞变形指数在第6天和第10天显著低于对照组（P〈0．05）,红细胞压积在第1、3、6、10天均显著高于对照组（P〈0．05）。治疗组添加中草药提取物复合制剂后,血液流变学指标得到了明显恢复,尤其在热应激的第10天疗效果最明显（P〈0．05）。试验结果说明,热应激刺激对仔猪健康有显著影响,中草药提取复合物可以降低这种热应激产生的生理损伤,其中中草药提取复合物Ⅱ效果优于中草药提取复合物Ⅰ。 相似文献

奶牛围产期血液流变学主要指标的变化规律 总被引：14，自引：1，他引：13
为了解健康奶牛围产期血液流变学的变化规律，对１５头围产期（产前９０ｄ至产后３０ｄ）奶牛血液流变学的全血高、低切变率粘度，全血高、低切变率还原粘度，红细胞聚积指数，红细胞压积（ＰＣＶ），血浆粘度等５项指标进行了系统检测。结果表明，在产前９０～５ｄ，上述５项指标均呈下降趋势，且分别于分娩前１０、８、５、３、１ｄ降至最低水平；产后１～３ｄ内，除ＰＣＶ外，上述４项指标迅速升高达最高值，产后１周以后，随着泌乳量的逐日增加而逐渐恢复到常态。 相似文献

本试验旨在研究高脂饮食对犬生化指标和血液流变学指标的影响。选取本地50只健康的45日龄杂交犬,随机分为两组,正常组15只,高脂组35只,分别饲喂基础饲料(正常组)、高脂饲料(高脂组)。试验为12周。每隔1周,采集1次血清,用于检测血清生化指标。于试验最后1d,每组随机选择15只犬,采集抗凝血,用于检测血液流变学指标。结果表明:与正常组检测结果相比,高脂组犬血清中TC、TG和LDL-C浓度均显著升高(P0.01或P0.05)。高脂组犬的全血黏度、红细胞压积、血浆黏度、全血高低切相对指标和全血高切还原黏度均显著升高(P0.01或P0.05)。由此可见,给予犬高脂饮食可出现高脂血症,并且血液流变学指标会发生明显的变化,对于犬高脂血的临床诊断,具有理论指导意义。 相似文献

胎衣不下奶牛围产期血液流变学指标变化 总被引：1，自引：0，他引：1
测定胎衣不下(RFM)奶牛围产期的血液流变学指标变化,为采取有效的预防和治疗措施提供依据。对25头胎衣不下奶牛和30头正常奶牛,使用锥／板法测定不同切变率的全血粘度,使用全自动激光衍射法测定红细胞变形能力。对照组全血粘度随妊娠时间推移,在妊娠后期显著或极显著降低。RFM组在切变率为150／s时未见显著降低变化,切变率为38／s、10／s、5／s有降低表现,但显著高于对照组(妊娠275d),分娩后10 d显著高于产后第1天。PCV随妊娠时间推移呈降低变化,妊娠275 d对照组显著降低(P<0.05),产后第1天两组均呈升高变化,对照组显著升高(P<0.05),随后两组各时间点均显著或极显著降低。红细胞变形指数产后呈降低变化,其中RFM组产后第1天显著低于产前,第30天显著低于产后第1天。积分面积在妊娠第275天对照组极显著增加,两组产后第1天均显著低于产前,RFM组产后第10天极显著低于第1天(P<0.01)。以上结果提示产前和产后血液粘度处于较高水平和产后红细胞变形能力的持续低下是RFM奶牛血液流变学的异常变化。降低分娩前后的血液粘度和提高产后红细胞变形能力可能有效减少RFM和其他围产期疾病的发病率。 相似文献

The effects of various concentrations of furosemide and pentoxifylline on equine RBCin vitro were evaluated to facilitate better understanding of the potential effects of these drugs on blood flow properties. Furosemide induced increased mean cell volume (MCV), increased RBC potassium concentration, increased whole blood viscosity, and decreased the RBC filtrability. These data indicate that furosemide may block the RBC membrane transport pathways resulting in potassium and water retention. The increase in size and the resultant decrease in the surface-area-to-volume ratio may have caused the impaired RBC filtrability and increased blood viscosity. Pentoxifylline improved RBC filtrability without changing the RBC size or the potassium or chloride concentrations, suggesting that pentoxifylline may increase the deformability of the RBC membrane. The study indicated that pentoxifylline has potential therapeutic applications for improving microvascular blood flow but that furosemide may have adverse effects on blood flow.Abbreviations cP

Background: The Reflovet system is designed for chemical analysis of whole blood. However, plasma or serum is recommended for potassium analysis because of possible interference from RBC potassium. Because RBC potassium concentration is low in most canine erythrocytes, however, there should be little or no interference.
Objective: The objective of this study was to compare potassium results obtained in whole blood and in plasma from dogs using the Reflovet system.
Methods: Blood samples were collected from 104 dogs into lithium-heparin tubes. The potassium concentration was measured in whole blood, and subsequently the PCV was measured. Samples were centrifuged and the potassium concentration was measured in plasma. Comparisons were made using Deming's regression and Bland-Altman difference plots.
Results: There was very good correlation between results of potassium measurements in whole blood and plasma ( r = 0.93). Potassium values were moderately lower in whole blood: Potassiumblood = 0.912 × Potassium plasma + 0.119. Hemolysis had a negligible effect on the results, but the difference increased with the PCV value. In more than 90% of samples, the difference between the 2 measurements was ≤ 0.3 mmol/L.
Conclusion: There is only a negligible difference in most cases between potassium values in canine plasma and whole blood using the Reflovet system. 相似文献

Whole blood viscosity (WBV) was measured on six healthy horses and ten horses presented for colic surgery. A Wells-Brookfield cone-and-plate microviscometer at 6 rpm was used to determine WBV and WBV was adjusted for packed cell volume (PCV). The ten colic horses were divided into two groups: five horses that died or were euthanatized (group 1) and five horses that were discharged after surgery and medical therapy (group 2). The mean WBV for each group was compared using analysis of variance followed by Duncan multiple-range tests. Mean WBV of group 2 (5.81 +/- 1.48 centipoise [cp]) and normal horses (7.1 +/- 2.3 cp) was significantly (P less than 0.01) lower than group 1 (17.15 +/- 5.71 cp). This preliminary trial shows that horses that died or were euthanatized had a significantly higher WBV than horses surviving. Since viscosity was adjusted for PCV, the differences may represent changes in other factors such as fibrinogen, rouleaux formation, red blood cell deformability, PaO2, or intracellular calcium ion concentration. Thus, increases in WBV in horses with colic may indicate severely compromised regional perfusion that may lead to significant tissue damage. In this preliminary study, it appears that WBV may be a prognostic aid in horses with colic. 相似文献

Body condition and haematological indices provide powerful information when assessing wildlife health. Reference intervals for these indices can facilitate wildlife management, and would benefit initiatives to save the Critically Endangered geometric tortoise (Psammobates geometricus). We collected data from 126 geometric tortoises to establish baseline values reflecting variation over four seasons (spring 2000 to winter 2001) and among three groups (female, male and juvenile). We measured body condition index (BCI; mass to shell volume), blood urea nitrogen (BUN), plasma chloride, packed cell volume (PCV), haemoglobin concentration (Hb) and red blood cell count (RBC), and used PCV, Hb and RBC to calculate erythrocyte indices. BCI correlated poorly with haematological measures but had a strong inverse relationship with BUN. BCI did not vary among groups, but all groups had low condition indices in autumn, the end of the dry season. High BUN and chloride values in autumn indicate dehydration, particularly in males. Males had the highest PCV, Hb and RBC values, especially during summer and autumn when they moved long distances, likely pursuing mates. Female and juvenile indices were similar, except that female Hb was higher than juvenile Hb, possibly to meet female energy needs associated with their large size and reproductive metabolism. Low Hb levels in winter coincided with low temperatures and reduced movements. Our results illustrate how intrinsic and extrinsic factors influence the physiology of geometric tortoises and provide reference intervals to monitor their health. 相似文献
