Purpose: The present study was undertaken to compare the function of the urinary
bladder, reflex changes of the urinary bladder, and bladder outlet, during micturition
between mature male and female rats.
Materials and Methods: Mature male(n=6) and female(n=6) Sprague-Dawley rats
weighing 250 to 300gm were used. After each rat was anesthetized with urethane(1g/§¸
a simultaneous recording of the intravesical pressure and voided urinary volume during
micturition were recorded. And then, the urethra was ligated placing 4-0 silk tie just
distal to the bladder neck. Isovolumetric bladder contractions and urethral pressure were
recorded independently.
Results: The voided volume and intravesical pressure during micturltion showed no
significant differences between mature fema1e and male rats. During reflex bladder
contraction, isovolumetric bladder contractions and urethral pressure also showed no
significant differences between mature female and male rats. Administration of
N-nitro-L-arginine(L-NOARG, 15§·/§¸), a nitric oxide synthase inhibitor, intravenously
in female rats, reversibly decreased the magnitude(42.5%, p<0.05) and duration(35.4%,
p<0.05) of reflex urethral relaxation. There was no effect on reflex urethral relaxation in
male rats. Administration of L-NOARG 20§·/§¸ intravenously in male rats reversibly
decreased the magnitude(49.8%, p<0.05) and duration(38.7%, p<0.05) of reflex urethral
relaxation.
Conclusions: From the results, it appears that the function of the urinary bladder and
the reflex change of the urinary bladder and bladder outlet during micturition showed no
significant difference between male and female rats of similar weight. Howerever, the
dosage of L-NOARG showed difference of the decreasing level of the magnitude and
duration of the urethral relaxation.
