SUMMARY: The concentration of total protein measured by photocolorimetric methodology and reported as units per 100 mg of tissue decreased from the initial segment to the cauda epididymidis of the Golden hamster, being significant the numeric difference observed between these two regions.
The highest concentration was observed in the initial segment (11.8[+ or -]4.12 mg protein/100 mg tissue) and the lowest concentration in the cauda epididymidis (5.1[+ or -]0.48 mg protein/100 mg tissue), with the difference being significant.
Sperm count in the cauda epididymidis
did not change in 1,2,3,4,6,7-HxCN-treated rats on postnatal day 89, the age of sexual maturity, but the sperm count in the cauda epididymidis
did increase to approximately 180% of the control value on postnatal day 62.
