Isolated innervated, rat and guinea-pig hemi-urinary bladder preparations.
Isolated innervated hemi-urinary bladder preparations of the rat and the guinea-pig have been described. In durability and behaviour to different frequencies of stimulation, the guinea-pig hemi-bladder is shown to give comparable results to those reported for the whole nerve-bladder. The rat hemi-bladder gave less durable contractions on prolonged stimulation. It is shown that the isolated guinea-pig hemi-bladder can be substituted for the isolated whole bladder preparation.
