Colonic myoelectrical activity in XXXX and @entity1142 .

@entity1 @entity235 @entity294 @entity158 @entity490 @entity1142 @entity1744 @entity1049
The electrical activity of the colon was recorded during 10 hour sessions from 4 to 8 sets of electrodes carried on a 1.5 m probe in 11 control volunteers and in 35 @entity1 with @entity1744 manifested by chronic @entity1142 , @entity294 and/or @entity158 . The patterns of electrical spiking activity were compared with that obtained from @entity235 with induced @entity294 or @entity1142 . In both @entity1 and @entity235 , two types of electrical activity were identified: short spike bursts (SSB) lasting 0.6 to 2.4 sec and long spike bursts (LSB) lasting 6.4 to 25 sec. The SSBs occurred at a maximum frequency of 13 per min. in @entity1 , while the LSB never exceeded 3 per min. Characteristic changes in the myoelectrical activity mainly coincided with disorders. In a group I containing 19 @entity1 , most of them exhibiting @entity1142 , the level of activity was 62% higher than in healthy subjects with an increase in the SSB hourly frequency of 170 to 420%. The colonic activity was similarly increased in constipated @entity235 . In a group II containing 11 @entity1 suffering from soft feces or watery @entity294 , the LSB activity was significantly reduced. In a group III containing 5 @entity1 , diffuse @entity490 occurred after eating despite a reduction of the electromotor feeding responses and the absence of colonic postprandial rushes. The results indicate that the functional @entity1049 in @entity1 corresponded mainly to 3 specific patterns of myoelectrical activity, one of them (Group I) being reproduced in experimentally constipated @entity235 .
