to elucidate the phenotypic expression of proliferating prostatic cells , rats were castrated , and the regenerating process of involuted ventral prostates during testosterone propionate ( tp ) administration was investigated by examining morphology , [ 5-125i ] iododeoxyuridine ( 125i-udr ) uptake , dna content , weight , acid phosphatase , and delta 4-steroid 5 alpha-reductase ( 5 alpha-reductase ) activities .
