  colonic motility
Among the hypothyroidism patients, 56.6% had decreased gastric motility, especially in gastric body and greater gastric curvature; 86.6% had decreased colonic motility, especially in the left half of the colon.
      
These changes in transmission processes and excitability in tissue from constipated patients are discussed in relation to altered states of colonic motility found in people with idiopathic chronic constipation.
      
More importantly, the precise factors that contribute to this therapeutic effect, such as modulations in cytokine levels and alterations in colonic motility, are being clarified.
      
The measurement of colonic motility in surgically repaired patients with a long-standing postoperative abnormality of bowel function can identify several distinct motility disorders that are amenable to separate and individualized therapies.

A2-hr manometry of decending-sigmoid colon was performed in 20 patients with IBS and 9 healthy volunteers. Neostigmine was administered following 1 hour of basal recording to determine the motor response. Plasma levels of gut hormones were investigated simutaneously. At basal state, constipation-predominant IBS(Cp-IBS) showed less frequent contractions in sigmoid colon(SC) and a lower percentage of contractile time(PCT) both in the sigmoid and in the decending colon(DC), whereas in diarrhea predominant type...

A2-hr manometry of decending-sigmoid colon was performed in 20 patients with IBS and 9 healthy volunteers. Neostigmine was administered following 1 hour of basal recording to determine the motor response. Plasma levels of gut hormones were investigated simutaneously. At basal state, constipation-predominant IBS(Cp-IBS) showed less frequent contractions in sigmoid colon(SC) and a lower percentage of contractile time(PCT) both in the sigmoid and in the decending colon(DC), whereas in diarrhea predominant type (Dp-IBS)only the amplitude(AMP) of contractions in DC decreased. The motor index of SC was incrreased in Dp-IBS but decreased in Cp-IBS.Post-neostigmine motor response was different among the three groups. In Cp-IBS, the motor response of SC as well as DC was exaggerated in the initial 30 mins but attenuated in the late 30mins. Cp-IBS had higher basal plasma levels of VIP and NT, and higher SST following neostigmine stunlation. Dp-IBS showed higher basal plasma SP Ievel than that in the controls, and NT level was persistently lower than that in Cp-IBS. Our data suggest that decending-siginoid colonic motility and its response to cholinergic stimulation are altered but is heterogeneous in both types of IBS.Abnormal release of certain gut hormones may be involved in its mechanisms.

对20例肠易激综合征(IBS)和9例健康志愿者的降-乙状结肠动力进行检测,并观察其对胆碱能刺激(新斯的明)的反应),同时测定刺激前后血中胃肠激素水平。结果表明,便秘型的乙状结肠或降结肠收缩频率和时间多降低,尤以降结肠明显,对新斯的明刺激的反应性较低;腹泻型在基础状态下,乙状结肠的收缩频率、持续时间及幅度略高或近似于正常,且动力指数升高。刺激后乙状结肠和降结肠收缩的某些指标增长高峰前移。表明结肠的反应性增高。患者血中SP、VIP、SST和NT的水平与正常有异,可能与动力变化有关。

The intensity of the stress effect on colonic motility was evaluated in eshour cold-restraint stressed rats. The contractile motility was recorded before, during and 1h and 60 hrs after stress. Motor responses to intraveveous exogenous peptides (VIP, SP, SST, NT) and to feedng were determined both during control and post-stYess periods. The motor indexes (MI) of both proximal and distal colon were elevated significantly during stress and persisted till 60 hrs after stress. Motor response to SP was enhanced markedly...

The intensity of the stress effect on colonic motility was evaluated in eshour cold-restraint stressed rats. The contractile motility was recorded before, during and 1h and 60 hrs after stress. Motor responses to intraveveous exogenous peptides (VIP, SP, SST, NT) and to feedng were determined both during control and post-stYess periods. The motor indexes (MI) of both proximal and distal colon were elevated significantly during stress and persisted till 60 hrs after stress. Motor response to SP was enhanced markedly in the post-sttessed period- Response to feeding was delayed and reduced in magnitude and duration. Besides, the fecal pellets were investigated for 72 hrs during pre-and poststress sessions. The number of fecal pellets was decreased but its water content was increased within 60 hrs after stress. The overall results suggest that stress has residual and multi-effect on colonic motility which may be relevant to the pathogenesis of colonic motor disorder.

对大鼠结肠收缩活动及排粪质量的观察发现,持续6小时的寒冷束缚应激引起其结肠动力显著增强,应激解除后60小时仍未恢复。应激尚可改变进食和P物质等生理性刺激引起的结肠动力反应。提示应激扰乱结肠运动的后续效应是多方面的,进一步支持应激与功能性肠病的可能联系。

Objective To explore the potential role of gut peptide in stress induced colonic motor disorder.Methods In 9 conscious Wistar rats pre equipped with strain gauge transducers on ascending and descending colon,colonic motility was recorded before,during and after stress.And colonic transit was evaluated by instilling 51 Cr into the cecum through chronically implanted cannula in each group of 16 rats with or without stress,and then calculating the geometric center(GC) of radioactivity.The contents of VIP,SP,NT,SST,MOT and Leu ENK in plasma,colonic mucosa and muscle layer were assessed in 16 stressed and 16 control rats.Exogenous peptides(VIP,SP,SST,NT)were intravenously administered in 9 rats to determine the colonic motor response.Also,the effects of peptides on colonic circular muscle strips were investigated.Resuits Motor activity was increased after stress,whereas colonic transit was delayed.In the stressed rats,plasma levels of VIP and Leu ENK were higher than those in controls.The content of Leu ENK in muscle tissue decreased.Both in vivo and in vitro studies showed that SP and NT excited,whereas VIP and SST inhibited colonic motor activity.Conclusion Release of certain peptides is altered by stress.Increased release of ENK and VIP may be involved in stress induced colonic motor disorder and in the regulation of“stress hormone”release.
