Microspectrofluorometric study of monoamines in the auricle of the heart of Protopterus aethiopicus.

abstract：:As luminal fluid moves from the seminiferous tubule and enters the rete testis, its protein concentration declines from approximately 6 mg/ml to 1 mg/ml. It was therefore suggested that protein is either 1) utilized by the spermatozoa, 2) transported across the epithelium of the terminal segment of the seminiferous tu...
