Abstract

Orchidectomy of cats resulted in a decrease of metallothionein (MT) in the dorsolateral and ventral lobes of the prostate and in the urethral gland to 21.2% (P<0.01), 88.4% (P>0.05) and 18.5% (P<0.01) of those of intact domestic cats respectively. With an increase of T dose to 5, 10, 15, 20, 25 #mu#g/kg bw, plasma T and MT contents in the dorsolateral lobe of prostate and urethral gland increased accordingly. Plasma T concentrations were positively correlated with MT contents in the dorsolateral lobe of prostate and urethral glands (P<0.01). Thus biosynthesis of MT in the dorsolateral lobe of prostate or in urethral gland could be induced by a stimulatory dose of T of 20#mu#g/kg bw.
