... region, and to a lesser degree in cells of the zona reticularis. Structural changes were seen in the mitochondria of these cells, which often became grossly enlarged and developed unusual electron-dense inclusions. In addition, the lipid droplets in the iron-deficient cells of these regions were much...

... swollen and disrupted mitochondria were found in groups S and S+T. The results suggest that administration of nandrolone decanoate may have some deleterious effects on the muscle respiratory system (capillaries and mitochondria). 4 04 1991 3 07 1991 16 7 2008 Acta Anal 1991;142:183-187...

...-chondrial matrix granules are more prominent than in those of the rat and mouse. Also distinctive are the Purkinje cells which, aside from their large size (30 µm) and lack of T-tubules, have atrial granule-like inclusions. These cells are well endowed with mitochondria (28% of cytoplasmic volume...

.... The luminal surface of cisterns of the granular endoplasmic reticulum and Golgi apparatus exhibited particles of 8-15 nm in diameter. The secretory canaliculi presented short microvilli which were irregularly arranged. The striated duct cells were characterized by rich mitochondria arranged vertically...

...A.S. Ayettey; C.N.B. Tagoe; R.D. Yates A comparative morphometric study of ventricular myocardial cells of the West African insect-eating bat, Pipistrellus pipistrellus the hamster and the rat revealed significant differences in volume fractions of mitochondria, myofibrils, lipid bodies and T...

... of severe cell injury, even though more extensive oedema is closely associated with sarcolemmal fragmentation. The fractional volume of mitochondria was smaller, whereas the fractional volume of lipid droplets was larger in cells with oedema than in cells without oedema. Morphometry Sarcolemma...

... with the outer mitochondrial membrane, nearby cytoplasm, endoplasmic reticulum and nuclear envelope. Once antrum formation has begun and the mitochondria have reached the dormant (storage) stage, cerium reactivity ceases. In adults, reaction occurs at the same stages of oocyte development but is weaker...

...Wayne Sampson; Ana Maria Montalvo The distance between mitochondria and the nearest plasma membrane was measured in actively secreting and nonsecreting exocrine glands in order to determine the effect of the secretory mechanism upon mitochondrial distribution. The greatest accumulation...

...M. Sharawy; G. Schuster; D. Pashley; P. Palmer Electron micrographs of resting and pilocarpine-stimulated acinar cells of mouse submaxillary glands revealed the majority of mitochondria in close association with lateral and basal portions of the acinar cell membranes. The qualitative observations...

... in the fine structure involved most of the organelles that are known to play vital roles in the biosyntheseis of corticosteroid hormones, namely, mitochondria, smooth endoplasmic reticulum (SER) and lipid droplets. The ultra-structural alterations showed remarkably wide variations at different time periods...

...W.D. Zwierzina Electron-microscopic investigations on the human adrenal cortex have been carried out in order to elucidate ultrastructural differences in the various zones. These studies indicate that certain differences in the ultrastructure of the mitochondria may be particularly useful...

... the entire cytoplasm and granular mitochondria with several peripheral cristae. Most cells, however, possess altered mitochondria, transformed into electron-dense masses, or clear vesicles with the possibility of digesting the ambient organelles. Other cells have clear vacuoles with similar digestive...

...Ruth Ludatscher; Michael Silbermann Premature female mice were injected daily with 1.5 mg/kg body weight of triamcinolone diacetate for 10 and 21 consecutive days. Electron-microscopic study of hepatocytes indicated the formation of ‘giant’ mitochondria concomitant with a marked increase...

... ratio, the chromatin appearance and the abundance of mitochondria. The three cellular types can phagocytose, but each one in a different way. The first one phagocytoses exclusively erythrocytes ‘by contact’ without emission of pseudopods; the second one phagocytoses degenerating nucleated cells...
