Objective To develop a canine model of neurogenic bladder and to evaluate it with urodynamics. Methods Eight female dogs were divided into 2 groups:4 in suprasacral and 4 in infrasacral group.The spinal cord was transected at the level of 5th~6th lumbar intervertebra foramen,and sacral cord was kept intact in suprasacral model while in infrasacral model it was destroyed completely.The urodynamic studies were performed in each dog at the time points of preopertation and 6 months postoperation in both groups.The parameters included bladder capacity,detrusor pressure,bladder compliance and urethral pressure. Results The dogs after operation could never move their tails and keep their hips dry.Their hind limbs presented flaccid paralyses and the abdomens dilated during the first postoperative week.Then the mobility of the hind limbs in both groups recovered slowly,but the abdominal signs were improved obviously only in suprasacral dogs.In suprasacral group,bladder capacity and compliance were decreased by 37.3% and 52.1%,respectively, but detrusor pressure (33.3%) and urethral pressure (17.3%) were significantly increased( P

Objective To compare the timeliness, success and mortality rates between the modified carotid artery puncture method ( MCAPM) and standard suture method ( SSM) in the establishment of rat model of a middle cerebral ar?tery occlusion ( MCAO) . Methods Thirty?two male rats were randomly and equally assigned into MCAPM group and SSM group. The MCAO models were established by inserting a thread into the common carotid artery ( CCA) . 24 h after modeling, the rats of the two groups were evaluated with Bederson neurological scores, and the modeling success rate and mortality rate were analyzed. Results The suture insertion times, success rates and mortality rates of the MCAPM vs. SSM groups were (82?3 ±17?4) s versus (164?6 ± 22?0) s (P<0?01), 87?5% versus 68?75% (P>0?05), and 6?25% versus 18?75% (P>0?05). Conclusions MCAPM can be used to establish the rat model of MCAO due to its simplicity, mild wound and feasibility.
