1, They are known to counteract both the vasoconstriction and the enhanced platelet aggregation present in the initial phase of migraine.

2, Coronary vasoconstriction has been suggested by several case-reports but full cardiac investigations have seldom been carried out.

3, Vasoconstriction and vasodilatation are separate mechanisms.

4, Histamine causes vasoconstriction and increased permeability of small venules.

5, The main pathological changes of PAH are vasoconstriction and arteriole organization afterward.

6, Both acute or chronic hypoxia can cause vasoconstriction and vasoconstriction increase.

7, Abnormal vasoconstriction of digital arteries and cutaneous arterioles due to a local defect in normal vascular responses is thought to underlie the disorder .

8, Results The intrarenal vasoconstriction in different stages of cirrhosis was significantly difference.

9, The vasoconstriction sends the lower limb vascular occlusion, hypertension, the stroke and so on.

10, In normal human pulmonary circulation, the 5 - HT1B/1Dreceptor mediates pulmonary vasoconstriction.

11, Moreover, in 2 species, inhaled NO administered before the intravenous infusion of HBOC can prevent systemic vasoconstriction without causing methemoglobinemia.

12, Invigorate the coffee contains acid, can prevent blood clots, hemolytic and enhance vasoconstriction, reduce stroke risk.

13, Background cell - free, hemoglobin - based oxygen carrier ( HBOC ) is systemic vasoconstriction.

14, Conclusions - These findings demonstrate that HBOC can cause systemic vasoconstriction by scavenging NO produced by NOS 3.

15, AIM: The aim of this study is to investigate the possible role of potassium channel in hypoxic pulmonary vasoconstriction (HPV).

16, The basic pathological alteration of pulmonary hypertension involves three dependent elements:pulmonary vasoconstriction, pulmonary vascular remodeling and pulmonary microvascular thrombogenesis.

17, The addition of epinephrine to local anesthetic solutions produces vasoconstriction.

18, Objective To investigate the mechanism and to explore the measures of prevention and treatment of hypothermal vasoconstriction .

19, Objective To compare the relaxant characteristics of cromakalim,(http://sentencedict.com/vasoconstriction.html) forskoline and nitroglycerin on agonists - induced vasoconstriction.

20, An Often Unrecognized Cause of Thunderclap Headache: Reversible Cerebral Vasoconstriction Syndrome.

21, Pulmonary vascular smooth muscle cell is an important executor of vasoconstriction and a key contributor of pulmonary vascular structure remodeling.

22, To investigate the mechanism and to explore the measures of and treatment of hypothermal vasoconstriction.

23, Additionally low arterial pressure triggers an adrenergic response with sympathetic - mediated vasoconstriction and often increased heart rate.
