The effect of chronic hypertension on acute hypertensive disruption of the blood-brain barrier has been studied in only two models of hypertension, with inconsistent results. The purpose of this study was to reinvestigate whether chronic hypertension has a consistent effect on acute hypertensive disruption of the blood-brain barrier and to determine whether one of the previously studied models ...

High blood pressure (hypertension) is a non-communicable disease that can cause death and many complications, especially complications related to the cardiovascular system. According data from Indonesian Basic Health Research (Riskesdas) in 2018, prevalence of hypertension Indonesia was 8.36%. Hypertension controllable risk factor for acute coronary syndrome. One causes rarely doing physical ac...

Cerebral vessels of the spontaneously hypertensive rat (SHR) are less susceptible to disruption of the blood-brain barrier to proteins during acute hypertension than normotensive controls. This protective adaptation in SHR during acute hypertension is thought to be due to cerebral vascular hypertrophy which leads to increased vascular resistance and attenuation of the increase in cerebral blood...

Acute aortic dissection is a common disease caused by primary tear in the aortic intima or rupture of vasa vasorum. Every year 5-30 per million are affected by that. Untreated aortic dissection (dissecting aortic aneurysm) carries a high mortality rate. More than 90% of acute dissections present with acute pain in chest or back or both. Aortic dissection may mimic other more common conditions...

The appearance of superoxide anion radical in cerebral extracellular space during and after acute hypertension induced by intravenous norepinephrine was investigated in anesthetized cats equipped with cranial windows. Superoxide was detected by demonstrating the presence of superoxide dismutase-inhibitable reduction of nitroblue tetrazolium. The superoxide dismutase-inhibitable rate of reductio...

One of the most common chronic medical conditions, affecting almost 30% of the population over the age of 20 years, and accounting for approximately 72 million people in the USA alone, is chronic hypertension [1]. While the chronic form of hypertension is more common than acute hypertension, the management of acute hypertension clinically represents a greater challenge. More frequent and severe...

During acute hypertension, Na(+)/H(+) exchangers (NHE3) retract from top to base of proximal tubule microvilli (MV) and Na(+) reabsorption decreases in proximal tubule. This study aimed to determine whether the actin-based motor myosin VI coordinately retracts with NHE3 in response to acute hypertension. BP was raised approximately 50 mmHg in rats for 20 to 30 min or sham treated, and kidneys w...

PURPOSE To consider the effect of chronic arterial hypertension on the susceptibility of the retina to acute IOP challenge. METHODS Anesthetized adult Long-Evans rats with normal (n = 5, receiving saline subcutaneously), chronic high blood pressure (BP) for 4 weeks (n = 15, Angiotensin II subcutaneously), and acute high BP for 1 hour (n = 10, Angiotensin II intravenously) underwent IOP elevat...
