本文对正常人和异常人的结肠胀气进行了研究。结肠气体的体积在不同的个体之间有很大的差异。在正常受试者中观察到的值为1.48 ml。一下CO2、H2和N2是结肠胀气的恒定成分; O2存在于大多数样品中，而CH 4和H2S偶尔缺乏。平均浓度。各种气体中CO_2，9%，O_2，3.9%，CH_4，7.2%，H_2，20%，N_2，59%，H_2S，0.0003%。正常人消化布鲁塞尔芽甘蓝后，排出的肠胃气量显著增加，而乳糖和牛奶对肠胃气的数量和成分没有影响。在患有结肠炎综合征的患者中，没有多余的气体排泄可以证明。乳糖和牛奶的摄入同样对amt没有影响。和肠胃气的成分。心脏失代偿患者的排气量未增加。
A study was made on colonic flatus in normal and abnormal individuals. The volume of colonic gas was found to vary considerably between different individuals; the avg. value observed in the normal subjects was 1.48 ml./minute. CO2, H2 and N2 were constant constituents of colonic flatus; O2 was present in most of the samples, whereas CH4 and H2S were occasionally lacking. The mean concns. of the various gases were: CO2,9%; O2,3.9%; CH4,7.2%; H2,20%; N2,59%; and H2S,0.0003%. Digestion of brussels sprouts by normal individuals was followed by a marked increase in the volume of excreted flatus, whereas lactose and cow''s milk were without effect on the quantity and composition of the flatus. In patients suffering from the colitis syndrome no excess gas excretion could be demonstrated. Intake of lactose and cow''s milk was likewise without effect on the amt. and composition of flatus in these subjects. The vol. of gas excreted by patients with cardiac decompensation was not increased.
