And Control

ABSTRACT Plasma levels of testosterone (T) and 5α-dihydrotestosterone (DHT) were determined by radioimmunoassay in 29 patients with benign prostatic hypertrophy (BPH) and in 56 control men of various ages. No significant difference was found in T, DHT nor DHT/T ratio between BPH and control subjects of similar age. Plasma DHT was higher in the prostatic than in the peripheral veins in 8/9 patients with BPH during laparotomy, indicating a prostatic secretion of DHT. No difference in the mean T nor the mean DHT was found in peripheral plasma before and after adenomectomy.

Human Prolactin

ABSTRACT The interaction between prolactin and zinc was examined in vitro in the human prostate gland. The results indicated that prolactin did not modulate the acute uptake of zinc into benign prostatic hypertrophy tissue whereas zinc, in contrast, increased the uptake of prolactin into the prostate gland. Our study further showed that the augmented uptake of prolactin by zinc was partly due to an increase in the non-specific binding properties of the peptide hormone. We were also able to demonstrate that the specific binding of 125I-labelled human prolactin to the receptor was reduced in the presence of zinc by a competitive mechanism. J. Endocr.

— Laser treatment of benign prostatic hypertrophy (BPH) has gradually become more widespread over the last few years. In the USA it is considered an alternative to endoscopic resection as far as insurance payments are concerned. Different methods are used but the most common and suitable one for urologists is the removal and coagulation of the prostatic tissue under visual control (VLAP or ELAP). The Authors report their personal experience in this type of treatment where good results are due to: 1) combination of a powerful, stable laser source 2) durable side-emission contact fibre 3) laser resector, which also in the absence of epicystostomy maintains a good flow during the operation. However, “laser resection” should still be considered an experimental procedure to be used for randomised protocols or on selected patients (high risk of bleeding, Jehovah's witnesses, carriers of pace-maker, etc.).
