查询词典 aorta

Our experiments demonstrated that norepinephrine-induced vasoconstrictive force, in rat aorta, was obviously modulated by temperature.

实验结果表明：在三种不同温度下，函数式中的常数X1间比较有显著性差异，P＜0.01；常数X2间比较无显著性差异，P＞0.05。

As the temperature of rat aorta was raised, the vasoconstrictive force and vasoconstrictive speed increased, and the effects of norepinephrine on vasculature were raised. The results suggest that the constant X1 for vasoconstrictive force is a factor sensitive to temperature.

认为NE引起的血管收缩张力的大小，显然也处于温度的影响之下；随着温度的升高，血管收缩张力变大，收缩速率变快，NE对血管的作用效力增强；且张力因子X1是温度敏感因子。

At the same time,the contents of angiotensin Ⅱand norepinephrine were decreased significantly in the medulla oblongata,hypothalamus,aorta,and left ventri-cle.The results suggest that in addition to the vasodilating effect nifedipine might als...

Aim: To study the effects of angiotensin receptor antaganist-valsartan on vascular hypertrophy、vasomotion function and aorta vascular smooth muscle cell EGF precursor mRNA expression in spontaneously hypertensive rats.

目的：本文探讨血管紧张素受体拮抗剂-缬沙坦对自发性高血压大鼠血管结构、功能以及主动脉血管平滑肌表皮生长因子前体 mRNA表达的影响。

Compared with SHRc , after 4 weeks, Pro-EGF mRNA expression level of SHRsv and SHRlv VSMC were significant lower.Conclusions: Valsartan decrease SBP of SHR, inhibit SHR VSMC proliferation, reverse vascular hypertrophy of thoracic aorta and mesenteric artery in SHR, improve the two arteries vasomotion function. Pro-EGF mRNA expression only in SHR VSMC, not in the VSMC of WKY. It indicated pro-EGF gene may play an important role in hypertension advance .

缬沙坦有效降压的同时，抑制SHR大鼠VSMC增殖，逆转其弹性血管和阻力血管的肥厚，明显改善其弹性血管和阻力血管的舒缩功能。pro-EGF mRNA只在SHR大鼠VSMC表达，而在WKY大鼠VSMC没有表达，提示pro-EGF基因可能在高血压的发生发展中起一定的作用，可能是高血压的一个病理机制。

This is a woundless, nonenzymatic method of obtaining highly purified primary endothelial cells of the rat aorta, especially practical for isolation and culture of small vascular endothelial cells.
