The radioimmunoassay of histamine release from circulating basophils in an in vitro study as support for the in vivo active systemic anaphylaxis test in the guinea pig
Comparative Haematology International - Tập 2 - Trang 162-165 - 1992
An in vitro anaphylaxis test is described which explores the ability of compound re-challenge to induce histamine release from polynuclear basophils in whole blood of guinea pigs that had previously been sensitised. This test is used in drug safety, in support of the in vivo active systemic anaphylaxis test, which is sometimes required by regulatory authorities, when the observed clinical signs ar......
The role of the bone marrow in bovine trypanotolerance II. Macrophage function inTrypanosoma congolense-infected cattle
Comparative Haematology International - Tập 9 - Trang 208-218 - 1999
Sequential biopsies of sternal bone marrow (BM) of three trypanosusceptible Boran and three trypanotolerant N'Dama cattle were examined by light and transmission electron microscopy before and up to 112 days postinfection (DPI) withTrypanosoma congolense. Before infection, the percentage of cells of the mononuclear phagocyte system (MPS) including the macrophage (Mϕ) and the calculated index of Mϕ......
Comparative erythrocyte metabolism in three species of marsupials from Western Australia
Comparative Haematology International - Tập 9 - Trang 86-91 - 1999
A comparative study was carried out to investigate various aspects of erythrocyte metabolism in three species of marsupials located in the western part of Australia. The burrowing bettong (Bettongia lesueur) and the Barrow Island euro (Macropus robustus isabellinus) were captured on Barrow Island whereas the mainland euro (Macropus robustus erubescens) was captured from the Pilbara region of north......
Morphological study and determination of M/E ratio of the haematopoietic cells of the duck
Comparative Haematology International - Tập 7 Số 2 - Trang 117-121 - 1997
In order to study the morphology of the haematopoietic cells of the native ducks of the north of Iran, bone marrow samples were collected from the proximal tibiotarsus bone of 10 healthy adult ducks. The bone marrow smears were stained using the Giemsa technique. The results indicated that the development and formation of blood cells in the bone marrow of ducks were similar to other birds, whereas......
Serum thromboxane generation by platelets in calves and adult cows
Comparative Haematology International - Tập 3 - Trang 52-56 - 1993
Baseline values for platelet numbers and thromboxane A2 generation during clotting were established in three age groups of cattle. In phase I when a small number of animals (n=9−11 per group) were sampled mean platelet numbers were significantly lower in adult cows (322.2 ± 21.3 × 109/l) compared to yearling heifers and newborn calves (479.4 ± 31.1 and 529.0 ± 58.1 × 109/l, respectively). Thrombox......
Characterisation of busulphan-induced myelotoxicity in B6C3F1 mice using flow cytometry
Comparative Haematology International - Tập 3 - Trang 102-115 - 1993
Three experiments were carried out to investigate the myelotoxicity of busulphan in female B6C3F1 mice using the Technicon H*1 and the Sysmex R-1000 flow cytometers, instruments which produce a full blood count and a differential leucocyte count, and an automated reticulocyte count, respectively. In Experiment 1, a single dose of busulphan was administered at levels from 0 to 60 mg/kg and blood pa......
Effect of saccharides on plasma mediated haemagglutination and in vitro phagocytosis by haemocytes of the snailLymnaea stagnalis
Comparative Haematology International - Tập 8 - Trang 43-49 - 1998
To study the role of lectins in the defence system of the snailLymnaea stagnalis, saccharides were tested for their capacity to inhibit plasma-mediated haemagglutination of trypsinised and fixed mouse red blood cells (M-rbc) and fixed rabbit red blood cells (R-rbc).d-Arabinose,N-acetylneuraminic acid, fucoidan andd-melezitose were good agglutination inhibitors using both types of rbc.d-Fructose, h......
Implication of clinical pathology in assessment of animal health and in animal production and meat inspection
Comparative Haematology International - Tập 5 - Trang 149-157 - 1995
Clinical, zootechnical and industrial developments of the last decades have led to new ideas on monitoring systems for animal production and meat inspection. Quality assessment systems, integrated monitoring, risk assessment concerning consumer's health and monitoring for infectious animal diseases, are more relevant today than pathomorphological control of individual subjects. Published papers on......
