Fig. (4) Tianma increased the contractile force and elasticity of the
thoracic aortic rings. Comparison of maximum contractile force
developed in response to 80 mM K+ and increasing concentrations
(CRCs) of PE in aortic rings from tianma-treated rats and controls.
The isolated endothelium-intact arterial rings were studied with the
endothelium left intact and data are presented as tension (g) per
milligram tissue wet weight (g/mg wet weight of aorta). Values
represent an average of 2x8 individual experiments. An asterisk
indicates a significant difference from the control value (*P < 0.05
compared to the control group).
