And the ressults were as follows. 1. In the cases with normal blood pressure, both the glomerular filtration rate and the renal blood flow ran parallel to age and decreased in comparative speed after 60 years old, and the filtration fraction showed no difference with that of youth and the reabsorption rate of the renal capillaries declined in some degree. 2. In the old age, with hypertension, the glomerular filtration rate showed a insignificant decline in comparison with that of the cases with normal blood pressure, and it declined with age.
