Abstract
The localization of phosphatases in the epididymis of Madras Red ram during
postnatal development was studied. The alkaline phosphatase activity was weak in the preweaning
and pre-pubertal periods but with the onset of puberty it was better observed,
especially in the epididymal epithelium. In the ductus epididymidis, the activity in the
epididymal tubules was greater than that in the inter-tubular area. Regional variations in
the enzyme activity were observed in the different segments. The acid phosphatase activity
changed during different stages of postnatal development. The weak activity in the preweaning
and pre-pubertal periods changed to moderate and strong in the different regions,
with the onset of puberty. The reaction in the different segments of the epididymidis was
varied with respect to the basal and apical areas of the epithelium. The adenosine
triphosphatase activity in the pre-weaning and pre-pubertal periods was weak. It changed
to moderate and strong in the different regions, with onset of puberty. The activity in the
epididymis was greater in the epididymal tubules than in the inter-tubular area. The activity
in the cauda region of the epididymis was stronger compared to the moderate activity in the
corpus and caput regions.
