BACKGROUND This study aims to present a novel method for using cardiovascular magnetic resonance (CMR) to non-invasively quantify the variation in pulmonary blood volume throughout the cardiac cycle in humans. METHODS 10 healthy volunteers (7 males, 3 female, age range 21-32 years) were studied. The blood flow in the pulmonary artery and all pulmonary veins was quantified during free breathin...

Currently, ultrasound machines are widely used in hospitals for the first diagnosis of various pathologies. There is also an Doppler method to determine and monitor blood flow. Through this method, it possible get information about general condition veins whether there any problems during examination clinic. But, does not have ability continuously veins. Continuous monitoring flow rate will fac...

Homocysteine is a chemical in the blood that is produced when an amino acid (a building block of protein) called methionine is broken down in the body. We all have some homocysteine in our blood. Elevated homocysteine levels (also called hyperhomocysteinemia) may cause irritation of the blood vessels. Elevated levels of homocysteine show an increased risk for (1) hardening of the arteries (athe...

•Almost all previous attempts to study the bronchial circulation have been limited to measurements of blood flow in the bronchial arteries and bronchopulmonary anastomoses. There have been two studies devoted to estimations of blood flow in the bronchial veins of the normal dog. In 1931, Berry and Daly perfused in dogs either the posterior bronchial artery of one lung or the entire aortic segme...

Received: May 08, 2017; Accepted: May 19, 2017; Published: May 22, 2017 A 49-year-old man was referred to us with a diagnosis of hematemesis by giant pipeline esophageal varices due to liver cirrhosis hepatitis C infection after carving a tattoo at 20-year age (Figures 1A & 1B). We reviewed the treatment strategy. Endoscopic injection sclerotherapy (EIS) was generally treated esophageal varices...

It has been documented that the cardiac musculature of many mammalia, including man, extends from the heart along the pulmonary veins to the lungs, and, at least in some rodentia, as far as the small venules, and that smooth muscle is not present (1-3). However, these reports are of structural studies only, and in the one publication where a speculation is made concerning the spread of the cont...

OBJECTIVE To investigate the effect of systemic administration of simvastatin on the retinal circulation. METHODS The effects of systemic administration of simvastatin on the retinal circulation after 90 minutes and after 7 days were studied in a placebo-controlled, double-masked, clinical trial among 12 healthy men. We used laser Doppler velocimetry to measure vessel diameter and blood veloc...

Varicose veins of the legs are known to have local secondary effects such as edema of the leg, eczema of the skin, ulceration and even hemorrhage. Sequelae such as thrombosis and phlebitis of the enlarged veins may in turn cause pulmonary emboli with their distressing pulmonocardiac symptoms. However, we can find no clear evidence in the medical literature that the pooling of blood in varicose ...
