Article: [Age-dependent changes of morphometric and histochemical characteristics of neurocytes in different ganglia of albino rats].
[show abstract] [hide abstract]
ABSTRACT: The aim of this study was to obtain the normative data on the age-dependent transformation of morphometric and histochemical characteristics of neurocytes in different ganglia in albino rats. Cell cross-sectional area, activities of cholinesterase (demonstrated with thioacetic acid method) monoamine oxidase (demonstrated with Glenner method) were measured in neurocytes of stellate, spinal, trigeminal and gastric ganglia in rats aged 2 to 360 days. Measurements were made with the help of "Bioscan" videoanalyzer. Informational analysis was used for the evaluation of the degree of maturation of neurocyte systems. General features, age- and organ-related peculiarities of morphometric and enzyme-histochemical characteristics were established for neurocytes of different ganglia, as well as a heterochronism of their definitive state attainment. The time of stabilization for neurocytes of stellate and I thoracic spinal ganglia was the age of 60 days, for those of trigeminal ganglion and intramural gastric ganglia -90 and 120 days, respectively. By this time, neurocyte systems turned from a determined state into a probabilistic-determined one, this transformation being considered as a population stabilization.Morfologiia (Saint Petersburg, Russia) 02/2004; 125(3):40-5. -
Article: [Enzyme and chemical characteristics of neurocytes of cervicothoracic ganglion of deafferented albino rats].
[show abstract] [hide abstract]
ABSTRACT: The influence of chemical deafferentation (capsaicin 50 mg/kg in dose) on age-related reorganisations of cervicothoracic ganglion neurocytes was studied. Disturbance of normal age dynamics of neurocyte area, change of neurocyte choline esterase and monoaminooxidase activity and ganglionic choroid plexus density within 6 months following neonatal administration of capsaicine were discovered. The changes were maximally manifested on d 30. Metric and histochemical parameters did not stabilise completely within observation terms.Morfologiia (Saint Petersburg, Russia) 02/2001; 119(2):25-8. -
Article: [Cellular composition of the spinal ganglion following neonatal administration of capsaicin in rats].
[show abstract] [hide abstract]
ABSTRACT: Single administration of 100 mg/kg of capsaicine to newborn rats causes 30% decline in neurocyte number, decrease of average area of section neurocytes and dystrophic changes of majority of cells developing in a month. In 3 and 6 months 60% decline of neurocyte number occur, increase of average neurocyte section area is retained, dystrophic changes in cells are less manifested. It was revealed through histogrammes that decline in neurocyte number was conditioned by reduction of fraction of small neurocytes. The results indicate the stable effect of chemical differentiation.Morfologiia (Saint Petersburg, Russia) 02/2000; 118(5):22-5. -
