Studies were carried out on 32 one-day-old broiler chickens, which were divided into a control and 3 experimental groups. Chickens in the control groups were fed, for 8 weeks with basic feeds, while chickens in the experimental groups were fed basic feeds enriched with monensin-natrium at the following doses: group I — 100 ppm, group II — 70 ppm and group III — 50 ppm. During the course and at the end of the experiment liver, kidneys, pancreas and heart were removed from both the control and experimental chickens for microscopic examination. First structural changes in the form of a small degree fat — droplet formation in liver cells were observed after 4 weeks of the experiment. 8 weeks after the beginning of the experiment, a significant degree of fat — droplet formation and swelling of Golgi apparatus structure were noted. The changes observed were associated with side — effect of coccidiostatic action on the liver of the experimental broiler chickens.
The aim of the study was to trace the content and location of iron in three types of oligodendrocytes in the cortex frontalis of the brain of thirty-day old Wistar rats. The assessment was achieved in a LEO OMEGA 912 AB electron microscope, using the ESI spectroscope method of mapping iron (Electron Spectroscopic Imaging). Differentiated iron content in the three types of examined cells was indicated. The greatest accumulation of iron was found in dark oligodendrocytes, a smaller accumulation in medium oligodendrocytes and the smallest in light oligodendrocyts. The article discusses the dependency between cytoplasm density and iron content in investigated types of oligodendroglia.
The aim of the study was to trace the content and location of iron in three types of oligodendrocytes in the corpus callosum and capsula interna of the brains of thirty-day old Wistar rats. The evaluation was achieved by Leo Omega 912 AB electron microscope, using the spectroscopy method of mapping iron ESI (Electron Spectroscopic Imaging). A variety within the iron content of the three different types of examined cells was indicated. The greatest accumulation of iron displayed dark oligodendrocytes, lesser - medium and the least - light oligodendrocytes. The paper discussed the relation between cytoplasm density and iron content in the studied types of oligodendroglia.
