Endocrine changes with prostatic carcinoma

Endocrine Changes with Aging

Over the last century, average life expectancy has dramatically increased. This can be attributed to medical advancements, including improvements in public health standards and living conditions as well as antibiotics and vaccination use, leading to an increase in youth survival and a shift in causes of death from infection to chronic conditions and non-communicable disease [1]. Old age, conven...

Cryoimmunologic Investigations in Patients With Prostatic Carcinoma

Arginase activity in prostatic tissue of patients with benign prostatic hyperplasia and prostatic carcinoma.

We studied arginase activity in human prostatic tissue in 15 patients with benign hyperplasia and 27 patients with prostatic carcinoma. Arginase specific activity is greater (p less than 0.0001) in prostatic carcinomas than in hyperplastic prostates. Arginase specific activity is correlated inversely (p less than 0.0001) with the histological grade of the tumor.

Prostatic hexosaminidase activity in patients with benign prostatic hyperplasia and prostatic carcinoma.

Hexosaminidase activity in prostatic tissue has been compared in 15 patients with benign prostatic hyperplasia and 15 patients with prostatic carcinoma. The ratio of enzymatic activity for the two substrates tested (p-nitrophenyl-2-acetamido-2-deoxy-beta-D-glucopyranoside and p-nitrophenyl-2-acetamido-2-deoxy-beta-D-galactopyranoside) was not significantly different in the two groups of patient...

Cystic Prostatic Carcinoma

We report a rare case of prostatic carcinoma associated with cystic degeneration. Cystic masses within the prostate are known. Benign cystic masses are more common and include congenital cysts of mullerian duct or mesonephric duct origin. Acquired cysts can be either retention cysts, parasitic or malignant in nature. Cysts accompanying prostatic carcinoma are moreover rare. The acute retention ...
