Motion Picture Studies on Degranulation of Horse Eosinophils during Phagocytosis
Horse eosinophil function has been studied in vitro by means of phase contrast cinemicrophotography. Locomotion of horse eosinophils was inhibited by serum factors reacting with glass surfaces. Under appropriate conditions which eliminated this inhibitory effect, eosinophils moved about and ingested some particles as rapidly as did neutrophils. Eosinophils were attracted to and readily engulfed...
متن کاملElectron Microscope Studies on the Degranulation of Rabbit Peritoneal Leukocytes during Phagocytosis
Electron microscopic observations have established the mechanisms underlying degranulation of neutrophils and eosinophils during phagocytosis. The content of the granules is released into the phagocytic vacuole when their membranes fuse with the membrane lining the vacuole. The discharge mechanism appears to be applicable to the various morphological types of granules seen in rabbit polymorphs....
متن کاملPhagocytosis by human eosinophils.
E OSINOPHILS were first recognized as a distinctive type of granulocyte over 100 years ago,’ and were observed to be capable of phagocytosis by Mesnil in 1895.2 Despite a voluminous literature on the morphology and functions of these cells, their precise role in normal man and in various diseases remains unclear. In general, eosinophils from higher mammals resemble other granulocytic cells in t...
متن کاملNonpathogenic, environmental fungi induce activation and degranulation of human eosinophils.
Eosinophils and their products are probably important in the pathophysiology of allergic diseases, such as bronchial asthma, and in host immunity to certain organisms. An association between environmental fungal exposure and asthma has been long recognized clinically. Although products of microorganisms (e.g., lipopolysaccharides) directly activate certain inflammatory cells (e.g., macrophages)...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
