    Abstract:
    The structure of different components from lumbar ganglia of the cat sympathetic trunk were studied in norm and 6h after intramuscular administration of prednisolone (5 mg/kg). Paraffin sections were stained with azocramine after Heidenhain, Wallart and Houette, azure II -- eosin. Biometry of different ganglial structures was performed by G.G. Avtandilov's dotted method. It was demonstrated that as a response to prednisolone administration, certain morphological changes appeared in all ganglial components. The walls of capillaries grew thicker, endothelial nuclei protruded into their lumen. Collagenous fibres of the connective tissue capsule and ganglial stroma grew thicker and acquired twisted appearance, the amount of the basilar substance increased. Simultaneously, there was a sharp increase of the nuclear section area in perineuronal ganglia. The total area of neuronal sections in the ganglia also increased at the expense of both increasing area of neuronal cytoplasm and hypertrophy of their nuclei.
