命案现场往往都会留有大量血迹,例如:有时犯罪嫌疑人受伤逃跑时会在沿途留下点状血迹:有时犯罪嫌疑人会把粘有血迹的凶器和衣物藏匿起来等.为了开拓警犬在命案现场上的使用领域,根据凶案现场上的特点,我们有针对性地开展了血迹搜索犬的训练,依靠血迹气味开展追踪和搜索,并在实战中取得了一些实效,现将训练的体会总结如下: 相似文献

Determination of intracellular acid-base status is reported in this paper by the example of erythrocytic haemolysate in dog. The difference between intracellular and extracellular acid-base ratios is highly significant and is of clinical relevance. Differences between species and the need for further experimental verification of the method are discussed in some detail. Reference values are suggested for orientation, on the basis of 20 experimental dogs. 相似文献

A 4‐year‐old neutered female crossbred Shepherd was referred for a history of 10 days of anorexia, polyuria, polydipsia, polyadenomegaly, and diarrhea. On physical examination, the dog appeared quiet, responsive, and apyretic, with generalized and severe lymphadenomegaly. Hematologic abnormalities included neutrophilic leukocytosis with left shift, and lymphopenia. Blood smears revealed intracytoplasmic bacilli negatively stained with May–Grünwald–Giemsa in neutrophils and monocytes. Lymph node smears revealed pyogranulomatous adenitis with calcified deposits and many negative‐staining rod structures, both within the cytoplasm of neutrophils and macrophages, and free in the background. An acid‐fast stain (Ziehl–Neelsen) confirmed the diagnosis of mycobacterial infection. The dog was euthanized for public health and ethical reasons, and the postmortem examination revealed severe and generalized granulomatous and necrotizing lymphadenitis, panniculitis, and hepatitis, and infiltration of epithelioid macrophages in the lungs, colon, and spleen. Numerous acid‐fast bacilli, consistent with mycobacterial infection, were observed both in the cytoplasm of epithelioid macrophages and giant cells, and free in the background. Mycobacterium bovis was first confirmed by conventional PCR of organ extracts. Mycobacterium avium was detected in a culture of the same organs. Further PCR amplifications and sequencing revealed a coinfection with 2 different species of mycobacterium, one belonging to the Mycobacterium avium complex and the other to the Mycobacterium tuberculosis complex. 相似文献

Relationships between blood pressure and haemorrheological factors were examined in three groups of dogs characterised by different levels of blood pressure. The groups used were sight hounds (high pressure), retrievers (low pressure) and a mixed group with intermediate pressure. The three groups had different levels of haematocrit and blood viscosity at both high and low shear rates, with the sight hounds showing the highest and retrievers showing the lowest levels for each of the parameters. The plasma viscosities did not differ significantly between the groups. Blood pressure and blood viscosity or haematocrit were not correlated within dog groups, but when the dog groups were considered together, significant positive correlations existed between pressure and viscosity and pressure and haematocrit. 相似文献

Neutrophilic leukocytosis (136,800 WBC/microliters) and multiple bone infarcts were detected in a dog with renal tubular adenocarcinoma. The causes of the leukocytosis and bone infarcts were not determined, but these syndromes appear to be uncommon manifestations of cancer in animal and human patients. 相似文献

Milrinone, a therapeutic agent for acute congestive heart failure, has both inotropic and vasodilatory effects, but investigations of these effects of milrinone were almost all conducted under normoxia, and few reports have investigated how milrinone affects the hemodynamics and redistribution of regional blood flow under severe hypoxia. By using colored microspheres, we investigated how milrinone affects hemodynamics and the redistribution of regional blood flow under severe hypoxia. Twelve healthy mongrel dogs were divided into 2 groups. The milrinone group was infused with milrinone cumulatively at 25, 75 and 250 microg/kg for 5 min each. The intact group was infused with saline instead of milrinone. We measured the hemodynamics and cerebrum, cerebellum and kidney blood flow in both groups. Both groups were inspired with 10% oxygen. Milrinone induced significant decrease in mean pulmonary artery and pulmonary vascular resistance, compared with the intact group. In both groups slight decreases in mean arterial pressure, systemic vascular resistance and double-product were seen. In regional blood flow, milrinone-induced increases in blood flow were seen in the cerebrum, cerebellum, and especially in the kidneys. Milrinone's vasodilatory effects were sufficient even under hypoxia. And milrinone increased regional blood flow slightly in the cerebrum and cerebellum, and significantly in the kidneys. These results suggested that milrinone protects against hypoxia-induced organ damage especially in the kidneys. In addition, milrinone is very potent in improving severe congested hemodynamics which complicates hypoxic pulmonary vasoconstriction. 相似文献

A method of arterial blood sampling acceptable for clinical purposes for acid-base estimations in dogs is described. A comparison of acid-base variables from fourteen canine arterial, venous and capillary blood samples revealed in most cases that venous and capillary blood samples showed unsatisfactory agreement with corresponding arterial blood samples. Two commercial automatic pH and blood-gas analysing systems are compared. 相似文献

Irregularly speculated red blood cells (IS-RBC) were quantified on fresh blood fixed in glutaraldehyde and were compared to RBC shape changes observed on Wright's-stained blood smears, RBC histograms, and RBC distribution widths (RDW). IS-RBC were infrequently found in healthy control dogs. Twenty dogs with increased IS-RBC were evaluated. The most common clinical diagnoses were lymphosarcoma (seven cases), glomerulonephritis (two cases), hemangiosarcoma (two cases), and chronic liver disease (two cases). Five cases had evidence of disseminated intravascular coagulopathy. In 12 of the 20 cases, keratocytes, schizocytes, and/or acanthocytes were detected in the monolayer area of blood smears. In the other seven cases, keratocytes, schizocytes, and/or acanthocytes were found only in thick areas of the smears. Acanthocytes were the most frequent cell type seen, while schizocytes were absent or present only in low numbers. RBC histograms had a shoulder on the left side of the tracing in six of the 20 cases, suggesting the presence of RBC fragments; however, cases with evidence of platelet aggregation had similar shoulders in RBC histograms. Red cell distribution widths were increased in 12 of the 20 cases with IS-RBC; however, the increase in RDW did not correlate with the presence of schizocytes and was most likely the result of reticulocytosis. This study suggests that quantitative evaluation of RBC shape is a more sensitive method for detection of mild RBC fragmentation when compared to blood smear evaluation, RBC histograms, or RDW. Additionally, acanthocyte-type cells were the most frequent shape change seen in dogs with evidence of RBC fragmentation. 相似文献

An EDTA‐anticoagulated blood sample collected from a 1.5‐year‐old, intact male, English Bulldog was submitted for a CBC. The CBC data and blood smear evaluation revealed borderline high hematocrit (54%, reference interval 37–55%), inappropriate rubricytosis, moderate leukopenia due to both mature neutropenia and lymphopenia, and mild thrombocytopenia. Numerous leukocytes showed evidence of karyolysis, pyknosis, and karyorhexis, and apoptotic bodies were frequent in the background. Many neutrophils had botryoid nuclei characterized by increased numbers of nuclear segments radially arranged with spoke‐like, delicate chromatin filaments connecting the segments centrally. The finding of botryoid nuclei and inappropriate rubricytosis was indicative of severe hyperthermia, such as heatstroke. The dog had been exercised a long time during conditions of high temperature and humidity until he collapsed. The dog was diagnosed with severe heatstroke, hypovolemic shock, disseminated intravascular coagulation, and multiorgan dysfunction syndrome. Despite aggressive treatment, the patient died of cardiopulmonary arrest. Botryoid nuclei are frequent in people with heatstroke. In the authors' experience, botryoid nuclei are seen commonly in dogs with heatstroke, but they have never been reported in veterinary medicine. The presence of petechiation with only mild thrombocytopenia and inappropriate rubricytosis also is suggestive of heatstroke and manifests ongoing life‐threatening vascular derangement. 相似文献
