Absorption of lactulose in man

, : Absorption of lactulose in man. Digestion 6(3): 139-145

Lactulose absorption was studied in 6 normal subjects. Lactulose was detected in the blood of only one. No changes were observed in blood glucose, galactose or lactate during the 24 h of the study in any of the volunteers. The amount of lactulose excreted in the urine was less than 1% of the dose in 5 subjects and 2.8% in the 6th. Lactulose was detectable in urine 2 h after ingestion. At 8 h, the excretion was almost completed, ranging by then from 77 to 100% of the total amount excreted.

For more than 80 years, ecologists have debated whether reproduction by female insect herbivores and parasitoids is constrained by the time needed to find hosts (time limitation) or by the finite supply of mature eggs (egg limitation). Here we pre...

The sural nerve is a cutaneous nerve of the lower limb that innervates the posterolateral aspect of the lower leg, ankle, and foot. Considering this pattern, it is plausible that it contributes to the maintenance of postural stability. However, th...
