Abstract

OBJECTIVE:

To study the kinetogenic effects of serum containing Semen Arecae, Dandelion, Semen raphani and Atractylodes macrocephala on the colonic smooth muscle cells of rats.

METHODS:

Serum containing Chinese materia medicas was made according to standard methods. Smooth muscle cells were isolated from the muscle layers of Wistar rat's colon, referred to modified Bitar's method. The contractile response of colonic smooth muscle cells to serum containing Chinese materia medicas (10%, 50%, 100% concentration) and other medicines (blank and 1 x 10(-3) mol/L acetylcholine) were separately observed. The contractility was presented by the decrease of the cell length between the drug groups and the control.

RESULTS:

Serum containing each Chinese materia medica can make dose-dependent contraction at different concentrations (P < 0.05), but the strongest effect of each serum had no significant difference (P > 0.05).

CONCLUSION:

Serum containing Semen Arecae, Dandelion, Semen raphani and Atractylodes macrocephala can make notable contraction on colonic smooth muscle cells in rats.
