类固醇的滥用会破坏胃肠道功能. 适度的运动可以抵消对肠道移动性和结构的一些有害影响.
科学领域:
- 胃肠病学 胃肠病学
- 药理学 药理学是指药理学的学科.
- 运动生理学 运动生理学
背景情况:
- 合成安卓类固醇 (AAS) 的滥用可能会损害胃肠道 (GI) 恒温.
- 有或没有运动的AAS对胃肠道过渡,收缩性和组织学的影响需要进一步调查.
研究的目的:
- 为了检查纳德罗隆二甲酸 (ND) 和中度游泳对肠道过渡,运动收缩性和大鼠肠道组织学的影响.
- 评估ND,运动和胃肠道功能之间的相互作用.
主要方法:
- 雄性Wistar大鼠在4周内通过肌内注射给予ND或载体.
- 群体接受了适度的游泳 (60分钟,体重超负荷为5%) 或保持久坐.
- 评估的参数包括胃排空,肠道过渡,体外肠道收缩性,肠道形态测量和十二指肠丸细胞.
主要成果:
- 在久坐不动的老鼠中,ND加速了胃的排空,并减缓了小肠的穿行速度.
- ND 减少了小的高度和粘膜的厚度,同时增加了十二指甲肌层的厚度.
- 适度的运动改善了肠道通道,并减少了下粘膜的厚度.
- 结合ND和游泳加速了胃排空,改变了十二指肠收缩性,增加了巨细胞,并降低了的高度.
结论:
- 纳德罗隆二甲酸显著改变肠道形态和功能,导致动力障碍,特别是在久坐的人群中.
- 适度的运动显示出补偿作用,减轻了ND的一些有害的胃肠道影响.
- AAS和运动之间的相互作用对肠道生理学产生了复杂的后果.
