[Influence of alum on intestinal flora in mice]
1Institute of Chinese Materia Medica, China Academy of Traditional Chinese Medicine, Beijing 100700.
Objective:
To observe the influence of alum on the intestinal microecological balance in normal microorganisms.
Method:
The mice were administered orally with alum of a small dosage(0.25/kg) and a large dosage(1 g/kg) for half a month, two months and three months, and a micro flora analysis of the mice was carried out at intervals of the above mentioned administrations.
Result:
The intestinal flora in the animals administered with alum was imbalanced. The counts of bifidobacteria and lactobacilli closely related to human physiological activities were decreased. The counts of pathogenic E. Coli significantly increased; and the longer the animals were treated with alum, the stronger the microecological balance was influenced.
Conclusion:
Alum could induce imbalance of the normal intestinal flora in mice.
