Vasoconstrictive Effect and Mechanisms of Taurine in Rat Abdominal Aortas 牛磺酸对大鼠腹主动脉的收缩作用及其机制的研究
During pregnancy, trophoblasts migrate from the placenta into uterine spiral arteries, transforming them into wide channels that lack vasoconstrictive properties. 怀孕期间,滋养层从胎盘迁移侵入子宫螺旋动脉,将这些动脉转化为缺乏收缩特性的管道。
METHODS: Hypoxia was induced in isolated aorta of guinea pig by gassing N2. The vasoconstrictive response of aorta to Ang ⅱ was recorded. 方法:冲氮气诱导离体豚鼠主动脉缺氧记录加AngⅡ后,主动脉的收缩变化。
This study suggests that long term residing at high altitude results in an increase in cerebral vasodilative response and a decrease in pulmonary vasoconstrictive response to acute hypoxia. 结果提示:高原移居平原者与世居平原者相比,脑血管缺氧性扩张反应较强,而肺血管缺氧性收缩反应较弱。
TURS resulted in rapid recovery in 26 patients after a prompt administration of intravenous 10% saline, vasoconstrictive drugs and diuretics. 经及时10%氯化钠溶液、血管活性药、利尿等治疗后,26例迅速恢复正常;
The effect of insulin on the vasoconstrictive effect of endothelin 1 ( ET 1) was evaluated on isolated WKY/ SHR aortic ring. 为观察胰岛素对内皮素-1(ET-1)缩血管作用的影响,将高血压大鼠(SHR)和正常血压大鼠(WKY)的离体主动脉环置于高出生理浓度的胰岛素环境中。
Effects of Temperature on the Vasoconstrictive Force of Norepinephrine in Rat Aorta 温度对去甲肾上腺素引起的大鼠主动脉收缩张力的影响
Effects of tetrodotoxin on biphasic vasoconstrictive responses to electric stimulation in rabbit saphenous artery 河豚毒素对电刺激诱发的兔隐动脉双相血管收缩反应的作用
Insulin increases the vasoconstrictive effect of endothelin 1 胰岛素增强内皮素-1的缩血管作用
The results show that the synthesis of vasoconstrictive prostaglandins ( PGE2 and PGF2a) in the renal medullary tissues of SHR is higher than that of normal rats, and this may have something to do with the development and maintenance of high blood pressure in SHR. 结果表明,SHR体内缩血管前列腺素(PGE2和PGF2a)合成量较正常大鼠升高,这可能与SHR高血压的出现和维持密切相关。
Endothelin ( ET) is a potent vasoconstrictive peptide which contains 21 amino acid residues. It has a molecular weight of 2492, free carboxyl and amino termini and has two intramolecular disulfide bonds. 内皮素(Endothelin,ET)是一种具有强收缩血管作用的二十一肽,有两个二硫键,分子量为2492,具有自由羧基和氨基。
METHODS Vasoconstrictive responses to Phe were recorded in the rabbit renal, femoral, saphenous, mesenteric, splenic and ear arteries. 方法采用兔离体肾动脉、股动脉、隐动脉、肠系膜动脉、脾动脉和耳中央动脉环标本的等长张力纪录法。
Comparison of vasoconstrictive effect of histamine on the isolated rabbit central and peripheral arteries in vitro and its mechanism 组胺对离体兔中枢和外周血管收缩作用的比较及其机理初探
Vasoactive peptides can regulate the vasoconstrictive and vasodilative function. 血管活性肽调整血管的舒缩功能。
Endothelin-1 ( ET-1) is the strongest vasoconstrictive peptide which could alter the kidney hemodynamic, Participates in the inflammatory response and remodeling of the renal vascular lesions, and as a result plays an important role in the process of vascular lesions in IgAN. 内皮素-1(Endothelin-1,ET-1)是目前所知机体内最强的缩血管活性多肽,可改变肾脏血流动力学,参与肾血管炎性反应及血管结构的重塑,在IgA肾病血管病变及疾病进程中具有重要作用。
any agent that causes a narrowing of an opening of a blood vessel: cold or stress or nicotine or epinephrine or norepinephrine or angiotensin or vasopressin or certain drugs
