Abstract
OBJECTIVE
To observe the changes of interstitial cells of Cajal (ICC) in stomach and small intestine of rats with honey-stir-baked Radix Polygalae, crude Radix Polygalae and its saponins, so as to study mechanism of crude Radix Polygalae reducing the motility disorder in gastrointestinal tract.
METHODS
Immunohistochemical staining was used to investigate the distribution of c-kit positive ICC in stomach and small intestine.
RESULTS
Compared with control group, the c-kit positive ICC in stomach and small intestine of crude Radix Polygalae and its saponins groups were both markedly decreased in model group (both P < 0.01), while honey-stir-baked Radix Polygalae group can not (P > 0.05).
CONCLUSION
The motility disorder in gastrointestinal tract caused by crude Radix Polygalae and its saponins may be associated with the changes of ICC number in stomach and small intestine. Honey-stir-baked Radix Polygalae can protect ICC in some extent.
