The nucleotides in normal human blood.
Approximately 15 ml. of venous blood were withdrawn and expressed into a chilled tube containing 0.30 ml. (300 U.S.P. units) of sodium heparin solution. After thorough but gentle stirring, 10.0 ml. were transferred by Folin pipette to 10 ml. of ice cold 10 per cent trichloroacetic acid. The mixture was thoroughly homogenized with a heavy stirring rod and centrifuged in the cold. The supernatant...
متن کاملBlood flow in the normal human retina.
The laser Doppler technique was used to measure the blood flow rate in 41 major vessels in ten eyes of healthy volunteer subjects. The specific relationship between blood flow rate, F, and vessel diameter, D, was determined for both retinal arteries and retinal veins. On average, F increased with increasing D at a power of 4.1, consistent with the presence of Poiseuille flow. In six eyes of six...
متن کاملOriginal Contributions Metabolism of Adenine Nucleotides in Human Blood
Biologically active concentrations of potently vasoactivc and platelet-active adenine nucleotides are generated in plasma by a variety of pathophysiological mechanisms. Although there is evidence that ATP and ADP are inactivated by endothelial ectonucleotidases, there has been little attempt to study the metabolic routes of their catabolism in blood or to assess the contribution of this process...
متن کاملProduction of cyclic nucleotides from normal human brain.
Concentrations of cyclic AMP and cyclic GMP in arterial and internal jugular venous (IJV) blood were determined at the resting wakeful state in thirty surgical patients without neurological deficits. The levels of cyclic AMP in artery and IJV were 32.1 +/- 3.0 and 40.0 +/- 4.1 pmol/ml (means +/- standard errors), respectively, while those of cyclic GMP in artery and IJV were 12.2 +/- 2.7 and 14...

Introduction: Cupping therapy (hejamat) is one of the therapeutic methods used in traditional medicine that it is still common in many of the contemporary societies. In spite of the progress of science, we have less information on the traditional and alternative medicine including cupping. With the study of mechanism of action of cupping, it will be more convincing for the traditional medic...
