Anaplastic Gangliocytoma with Eosinophilic Cytoplasmic Granules in a Cow.

Formation of cytoplasmic granules in human eosinophilic myelocytes: an electron microscope autoradiographic study.

T HE CYTOPLASMIC GRANULES of eosinophils may be considered a form of lysosome, for they are membrane bounded structures containing, among other substances, hydrolytic enzymes.’ These granules appear in the immature cell as large membrane bounded structures with a homogeneous electron dense content; as the cell matures, a crystalloid inclusion commonly develops within the granule.2.3 Electron mi...

Intranuclear crystalloids associated with abnormal granules in eosinophilic leukocytes.

Ultrastructural evaluation of eosinophilic leukocytes from a 2-yr-old asymptomatic girl with chronic benign neutropenia (CBN) revealed a variety of morphological abnormalities. All eosinophils obtained from blood and marrow specimens contained multipole microcrystalloids in most of the mature cytoplasmic granules. An increase in crystalloid-free, immature granules in late (bilobed nuclei) eosin...

Eosinophilic myositis due to Sarcocystis hominis in a beef cow.

A case of eosinophilic myositis (EM) in an 8-year-old beef cow was investigated. The animal originated from a herd in which a high incidence of the disease had been observed in slaughtered adult females over a period of 2 years. Histologically, the lesions in the muscles were characterized as granulomas with a central core of degenerate eosinophils and remnants of necrotic muscle fibres, surrou...

Cytoplasmic mRNP granules at a glance.

Introduction From their transcriptional birth to their degradation, cellular mRNAs are coated with proteins in messenger ribonucleoprotein (mRNP) complexes. The mRNP composition controls every aspect of the life of the mRNA, from pre-mRNA processing to mRNA localization, translation and turnover. Transitions between these events are accompanied by major mRNP remodeling and exchange of mRNP prot...
