چکیده
Antibodies specifically reacting with platelets only in the presence of EDTA. by the platelet immunofluorescence test. were found in the serum of 20 patients with pseudothrombocytopenia due to in vitro EDTA-dependent platelet agglutination. These antibodies reacted optimally at 0-4’C. In 1 9 patients. IgG antibodies were detected; in 8 patients. 1gM or IgA antibodies were also found. In one patient. only IgM antibodies were found. In 14 patients. the lgG antibodies were IgGi . but lgG2. lgG3. and lgG4 antibodies

متن کاملPseudothrombocytopenia: an immunologic study on platelet antibodies dependent on ethylene diamine tetra-acetate.
Antibodies specifically reacting with platelets only in the presence of EDTA, by the platelet immunofluorescence test, were found in the serum of 20 patients with pseudothrombocytopenia due to in vitro EDTA-dependent platelet agglutination. These antibodies reacted optimally at 0-4 degree C. In 19 patients, IgG antibodies were detected; in 8 patients, IgM or IgA antibodies were also found. In o...
متن کاملEffect of ethylene diamine tetra acetic acid chelator in the presence of chromium on growth and some physiological characteristics of sunflower.
Chromium is a heavy metal toxic for plants that due extensive industrial applications over the last decade, has become a serious environmental pollution. On the other hand, chelator dissolution and absorption of metal by the plant increase and their use in phytoremediation is important. The aim of this study was to evaluate the effect of different concentrations of chromium and ethylene diamine...
متن کاملCompleximetric determination of calcium in pathological and physiological specimens.
Titrimetric estimation of calcium with disodium ethylene diamine tetra-acetate (E.D.T.A., sodium edetate), as performed on serum (Baron and Bell, 1957), cannot be applied directly to most other biological specimens because of their high concentration of phosphate. A high ratio of phosphate to calcium in the material titrated causes a drawnout and inaccurate endpoint. A rapid procedure for calci...
متن کاملImmunological evidence for the presence of latent Ca2 dependent ATPase and carboxydismutase on the thylakoid surface.
Antibodies were prepared against carboxydismutase and latent Ca2® dependent ATPase (coupling factor) purified from Nicotiana tabacum. The antibodies against carboxydismutase inhi bit the enzymatic activity of the purified protein, while those against coupling factor inhibit the Ca2© dependent ATPase activity of the protein as well as the photophosphorylation of the chloro plasts. The antisera...
