“…This discrepancy could be attributed to the segment examined, as has been found in the camel in which supranuclear and basal reactions were encounted in the middle segment and in the initial and terminal segments respectively. With regard to non-specific esterase, and with the exception of the ram in which maximal activity was noted in the middle segment (Moniem & Glover, 1972), the observations on the camel are similar to those in the epididymides of rat, rabbit and hamster (Allen & Slater, 1957;Moniem & Glover, 1972) and bull (Erkmann, 1971).…”

Studies of the functional activity of the lining epithelia have included absorption of vital dyes such as trypan blue and India ink (Mason & Shaver, 1952;Shaver, 1954;Macmillan, 1957;Macmillan & Clegg, 1963;Burgos, 1964Burgos, , 1967Sedar, 1966;Friend & Farquhar, 1967), incorporation of isotopes (Orgebin-Crist, 1964) and sperm and fluid résorption under normal and experimental conditions (Crabo & Gustafsson, 1964;Crabo, 1965;Nicander, 1965;Holstein, 1967;Hoffer, Hamilton & Fawcett, 1973).…”

“…The delimitation and segmentation of the proximal part in mouse epididymis whose structure complexity was recognized (Benoit, 1926; Allen and Slater, 1957; Blecher and Kirkeby, 1978; Takano, 1980; Soranzo et al, 1982) was investigated by the systematic application of macroscopical, histological, ultrastructural, and histochemical observations.…”

Regional differences in the proximal part of mouse epididymis were reported to provide a morphological baseline for studies on functional zonation of this part that is critical in sperm maturation. Macroscopical, histological, ultrastructural, and histochemical observations permitted us to subdivide this part into five segments, characterized by epithelial height, nuclear position, cytological and histochemical features of principal cells. Segment I corresponded to the initial segment previously described in rodents. Segment II differed from segment I by endoplasmic reticulum (ER) and dictyosomes aspect in principal cells, apical alkaline phosphatase and Ca2+-dependent ATPase activities. Segment III was characterized by spermatozoa package, high content of cells in multivesicular bodies, mitochondria shape, complex interdigitating membranes, and strong periodic acid-Schiff (PAS)-positive cell border. Segments IV and V presented the same cytological features but differed by their esterase activity. In the principal cells of each segment, dense spherical concretions were scattered in ER caveolae. Cells with apical nuclei were classified into two groups. The cells of the first group presented the same morphological and histochemical features as the adjacent principal cells and were scattered in the five segments ("apical cells"). The cells of the second group differed from the others by their goblet shape, a dense cytoplasm, and a high mitochondria succinate-D activity. They presented different cytological and histochemical features depending on their localization in segments I ("narrow cells"), II ("prominent cells"), or III, IV, V ("mitochondria goblet-cells"). The possible relationships between epithelium structure and epididymal functions were herein discussed.

“…The distribution of alkaline phosphatase activity has been reported in the epididymides of the mouse [Allen and Slater, 1957], rat [Maneely, 1959;Marian and Risley, 1963], hamster [Malone and Bower, 1962], rabbit [Nicander, /1958aLinnelz and Amann, 1968], stallion, ram and bull [Nicander, /1958b, But, other than for the work of Allen and Slater 11959] and Allan [1961] in the epididymis of the mouse, no com plete studies of the distribution of the other enzymes mentioned above appear to have been undertaken on mammalian epididymides.…”

The activity of enzymes hydrolyzing sodium-β-glycerophosphate, adenosine triphosphate, adenosine monophosphate, and glucose-6-phosphate in the epididymides of adult ram, rabbit, rat and hamster has been investigated histochemically. The enzymes hydrolyzing sodium-β-glycerophosphate, adenosine triphosphate and adenosine monophosphate were rather similar in their distribution in the intertubular connective tissue of the epididymides of the four species studied. However, the distribution and activity of these enzymes in the stereocilia varied. There was a high activity in the stereocilia of the middle segments of ram, rabbit and rat and in the proximal part of the terminal segment of hamster epididymides. Glucose-6-phosphatase was distributed homogeneously in the epithelial cells of the epididymides throughout the duct. The possible functions of these enzymes in the mammalian epididymis are briefly discussed.
