“…Mean body length measured 24.3 cm in males and 20.8 cm in females, and mean tibia length was 4.62 cm for males and 4.02 cm for females. There was little difference be tween these values and the measurements of rats in good condition {Berg and Harmison, 1957).…”

“…These weights were 25% lower than maximum weights at younger ages before disease set in {Berg and Harmison, 1957). Mean body length measured 24.3 cm in males and 20.8 cm in females, and mean tibia length was 4.62 cm for males and 4.02 cm for females.…”

“…Although the present finding of signi ficantly lowered PRA in aged rats differs from previous reports, this is probably due to differences between the ages of the rats. Since the average life span of rats is 24 months [2], the rats examined in the previ ous investigations were probably not suffi ciently old for the results to shed light on the influence of aging on the renin-angiotcnsin system.…”

To investigate the relation between renin content in each juxtaglomerular apparatus and reduction of plasma renin activity (PRA) with aging, the PRA and microdissected superficial or juxtamedullary single nephron renin content (SNRC) were determined in 5 young (3–6 months) and 5 aged (13–18 months) rats fed on a normal salt diet. The mean value of the PRA in the aged group was significantly lower than that of the young group. A highly significant correlation was found between the RPA and mean values of the superficial SNRC. The mean values of both the superficial and deep SNRC in the aged rats were significantly lower than those of the corresponding zones in the young rats. It is suggested that decreased synthesis of renin in each juxtaglomerular apparatus is an important factor in the decreased PRA observed with aging.

“…• Como já demonstrado em experimentos anteriores, o osso do rato assim como o do homem, não cresce continuamente durante a sua vida (KALU, 1991;YU et al, 1982;BERG & HARMISON, 1957). No rato, ocorre um rápido crescimento até 6 meses de idade.…”
