Role of Bladder Nerve Growth Factor on the lower Urinary Tract Dysfunction

雌性Wbister大鼠出生后10周脊髓损伤后1周、2、3、4周膀胱重量分别为153.7<正负>51.7、241.2<正负>112.7、176.6<正负>136.6、544.0<正负>213.3 mg。体重分别为133.3<正负>7.5 g, 140.0<正负>8.2 g, 158.9<正负>16.6 g, 125.0<正负>16.6 g。对照大鼠出生后10、11、12、13、14周膀胱重量分别为60.6<正负bbb5.6、43.9<正负>6.2、42.2<正负>6.0、41.5<正负>6.5、40.5<正负>5.9 mg。身体重量显示分别为160.0 <加减> 4.5,162.0 <加减> 7.5,166.0 <加减> 8.0,161.0 < plus-miThe控制膀胱的神经生长因子测量11日12日13日,出生后14周显示分别为326.9,478.5,85.5,和65.7 ng / g湿重。脊髓损伤后1周、2周、3周、4周膀胱NGF含量分别为292.5、392.4、280.3、708.2 ng/ g湿重。我们没有发现对照组和脊髓损伤组膀胱NGF的数量有显著差异。在胸椎和腰椎交界处脊髓损伤的手术可能会降低骶骨排尿中枢的活动。膀胱NGF在各种下尿路神经源性功能障碍中的确切作用有待进一步研究。

In female Wbister rats, bladder weights at 1 week, and 2, 3, 4 weeks after spinal cord injury on 10 weeks after birth showed respectively 153.7<plus-minus>51.7, 241.2<plus-minus>112.7, 176.6<plus-minus>136.6, and 544.0<plus-minus>213.3 mg. Body weights showed respectively 133.3<plus-minus>7.5, 140.0<plus-minus>8.2, 158.9<plus-minus>16.6, and 125.0<plus-minus>16.6 g. In the control rats, bladder weights at 10, 11, 12, 13, 14 weeks after birth showed respectively 60.6<plus-minus>5.6, 43.9<plus-minus>6.2, 42.2<plus-minus>6.0, 41.5<plus-minus>6.5, and 40.5<plus-minus>5.9 mg. Body weights showed respectively 160.0<plus-minus>4.5, 162.0<plus-minus>7.5, 166.0<plus-minus>8.0, 161.0<plus-miThe amount of NGF measured in control bladders at 11, 12, 13, 14 weeks after birth showed respectively 326.9, 478.5, 85.5, and 65.7 ng/ g wet weight. While, the amount of NGF measured in the bladders at 1 week, and 2, 3, 4 weeks after spinal cord injury showed respectively 292.5, 392.4, 280.3, and 708.2 ng/ g wet weight. We could not find a significant difference between the amounts of bladder NGF in the both control and spinal cord injury groups.The procedure of the spinal cord injury at the junction of the thoracic and lumbar vertebrae might decrease the activity of the sacral micturition center. Further study is necessary to determine exact role of the bladder NGF on the various lower urinary tract neurogenic dysfunction.
