[Effects of Sijunzi Decoction on urine's xylose excretion rate and ATP in mucosa of spleen deficiency rats].

Objective: To observe the effects of Sijunzi Decoction on D-xylose excretion rate and ATP content in the mucosa membranes of small intestines of rats with spleen deficiency.

Methods: Spleen deficiency model rats were made by reserpine injection. D-xylose excretion rate was measured with p-bromoaniline method, and the ATP content of small intestines mucosa was detected with bioluminescence method. The correlation between D-xylose excretion rate and ATP content of mucosa was also analyzed.

Results: Rats' body weight and D-xylose excretion rate decreased after reserpine injection (P < 0.01, vs control group), but increased after treated with Sijunzi Decoction (P < 0.05, vs model group). The ATP content of mucosa showed no significant difference between model group and control group. There was obviously positive correlation between the change of urine's D-xylose excretion rate and mucosa ATP content.

Conclusion: Sijunzi Decoction has the activity of improving xylose absorption in spleen deficiency rats, but no obvious effect on their mucosa ATP content. The reducing of urine's D-xylose excretion rate in spleen deficiency rats is accompanied with the decrease of mucosa ATP content.
