Prostate gland and epididymis phosphatase isoenzymes: comparisons of young adult and aged rats.
Relative activities of acid and alkaline phosphatases in rat reproductive tissue were studied in young adult (10-12 months) and aged (30-34 months) rats. Prostatic alkaline phosphatase alone increased in aged animals. Moreover, prostate preparations contain two isoenzymes of alkaline phosphatase whereas only one was found in epididymal tissues. Age-associated changes in the prostatic alkaline phosphatase isoenzyme ratios were observed. No significant age-related changes in acid phosphatase tartrate sensitivity were found. Techniques for the preparation of prostate and epididymis tissue extracts are reported.
This article is the second of two parts. The first one was published in the issue no 2 of this same journal. The preseni study uses the dependency index and the youth ratio to describe the aging process both at regional and municipal levels. Our data show a yet moderate aging process in (he region. with an uneven distribution throughout the different municipalities.
