使用CM型氢气气体微分析仪对170名正常人进行乳糖吸收不良测验。年龄4~90岁。结果:乳糖吸收不良者(肺泡气含氢量>20ppm)133名,占78.24%。与国外报道东方人的结果相似。各年龄组相比,成人组乳糖吸收不良占85.4%,儿童组占48.48%。儿童组肺泡气含氢量的峰值显著低于成人组,且峰值出现时间又为各年龄组中最迟者。说明乳糖酶缺乏可能是个体发育中的现象。 相似文献

正常成年人对牛奶和酸牛奶中乳糖吸收程度和不耐受程度的调查 总被引:3,自引:0,他引:3
采用无损性、灵敏的氢气呼吸试验,对30名在摄入半磅牛奶和半磅酸牛奶后的成人乳糖吸收和不耐受程度进行了观察。结果表明。摄入牛奶后,4人牛奶乳糖完全吸收(13.3%),26人乳糖吸收不良(86.7%)。其中1人(3.3%)轻度吸收不良,16人(53.3%)中度吸收不良,9人(30%)重度吸收不良。 饮牛奶者和改饮酸牛奶者的不耐受率和不耐受指数分别为53.3%,6.7%和0.9,0.067。 牛奶乳糖吸收不良者在8小时内平均多排出的氢气量为60.34±30.57(ml),酸牛奶为14.97±13.64(ml)(p<0.01),提示酸牛奶中约75%的乳糖转化而吸收。酸牛奶有“自动消化乳糖”的作用,可弥补内源性乳糖酶的缺乏。 相似文献

Our digestive disease section performed lactose
tolerance tests in t31 normal Chinese using the
Hydrogen Breath Microlyzer Type CM made by
Quintron Instrument Corp., USA. Subject age rang-
ed from 4 t0 58 years. There were 81 males and 50
females, a male to female ratio of l.62:1. 103
(78.63%) of the subjects were lactose intolerant, their
pulmonary alveolar air hydrogen being greater than
20 ppm, similar to the percentages found in orientals
investigated in the USA. Comparison by age groups
showed that Iactose intolerance in adults was 85.85%,
lactose intolerance. Lactose intolerance was 4T83%
In children it was 47.83%. The alveolar air hydrogen
gas peak in children was significantly lower than that
of adults. The appearance of the hydrogen gas peak
was delayed in all children's age groups. This sug
gests that lactose intolerance is probably develop-
mental in all with this defect. We consider that
H7 breath test is of diagnostic value in many alimen-
tary disturbances. It is simple to perform and
worth further study. 相似文献
