Age-related changes of glomerular basement membrane in normal rats.
The structural changes of the renal glomeruli in development and aging were investigated by electron microscopy in normal rats from 4 to 36 weeks of age at 4 weeks intervals after birth. Infantile rats had an uneven glomerular basement membrane which was characterized by double-layered or mossy appearances of the lamina densa. On the other hand, diffuse and hemispherical thickenings of the base...

Forty-five open-chest male Wistar rats at 6, 12, and 24 months of age were used in this study. Work performance of the...
متن کاملAge-related and light-associated retinal changes in Fischer rats.
Morphological changes in retinas of aging Fischer 344 rats were characterized. The numbers of photoreceptor cells gradually decreased as rats aged. The outer nuclear layer was 12 cells thick at 3 months, but was reduced to less than 8 cells by 18 months. The decrease of photoreceptor cells was more pronounced in rats housed under a light intensity of 32-ft-c than in rats housed under a light in...
متن کاملAge-related retinal function changes in albino and pigmented rats.
PURPOSE To investigate the effect of old age (3 vs. 18 months) on the retinal function of albino (Sprague-Dawley [SD]) and pigmented (Long-Evans [LE]) rats. METHODS Electroretinograms (ERG) were recorded in both albino (SD; 3 months old n = 16, 18 months old n = 16) and pigmented (LE; 3 months n = 16, 18 months n = 5) rats. Data are analyzed for photoreceptor, ON-bipolar, and retinal ganglion...
متن کاملEmotional changes related to age in rats--a behavioral analysis.
The present study investigated age-related differences in the emotional behavior of rats using factor analysis to identify motivational factors influencing spontaneous behavior in open field with illuminated center (OF), plus maze (EPM) and social interactions test. Animals of the same strain, bred under the same conditions, formed two experimental groups: young adults (YA, N=20) tested at the ...
