ABSTRACT
AIM:
To investigate the alteration of the vascular response to contracting material and the endothelium dependent vascular relaxation (EDVR) at different stages of type Ⅱ diabetes rats.METHODS:
Type Ⅱ diabetes rat model was established by high-energy diet and lower dose of STZ. At 12th and 20th weekends after injecting STZ, the vascular reactivities to phenylephrine (PHE) and KCl and the EDVR induced by Ach were measured respectively in the isolated aorta rings.RESULTS:
At 12th weekend after injecting STZ, the response to PHE increased, the reactivity to KCl kept unchanged, and the EDVR was damaged lightly. But at the 20 th weekend after injecting STZ, the response to PHE increased further and the reactivity to KCl markedly reinforced, and the EDVR was obviously damaged.CONCLUSION:
The response of great vessels to contracting material increased, but the EDVR attenuated at different stages of type Ⅱ diabetes rats. These changes are further reinforced along with the developing of disease duration.
