throughout the world, millions of muslims fast daily during the month of ramadan from sunrise (sahar) until sunset (iftar). considering the impacts of environment on physiological functions, we performed this study in order to examine the effects of ramadan fasting on some blood parameters of healthy volunteers and hypertensive patients. according to the results, there were no significant chang...

the human blood basal glucose level is a completely controlled range. information on the relationship between culture glucose concentration and changes in the cell's surface area, volume and surface area to volume (s/v) ratio are lacking. cancerous epithelial-like cell lines sw480, sw742 and t-47d were cultured in mediums nourished with 4.7 mm per liter of glucose as the control group and three...

THE ESTIMATION OF PLASMA VOLUME has become a very useful and widely applied tool in the diagnosis and treatment of clinical aberrations of water and electrolyte distribution. Methods utilizing the dilution of radioactive iodinated serum albumin (BISA), have been studied and applied extensively, and most of the strictly methodologic difficulties have been overcome. One step, however, that of inj...

Under physiological conditions and on average, the total volume of blood in the circulation is constant. The total blood volume (BV) and the separate volumes of plasma and erythrocytes vary according to climatic conditions, in pregnancy and in the presence of disease. Such changes can have clinical significance although they are rarely revealed in common clinical practice because of a lack of a...

• The development of catheterization and indicator dilution techniques has made it possible to measure the volume of circulating blood within many organs in the intact animal. Hirche and Lochner injected measured amounts of dye into the coronary arteries of dogs and recorded the subsequent time course of dye concentration in blood from the coronary sinus. From this single curve both coronary bl...

We have measured the effects of barium-induced cardiac contraction on the intramyocardial blood volume content of all vessels and have independently measured the blood volume content of vessels with a diameter greater than 100 ,um in rat myocardium. Measurements of total intramyocardial blood volume were made by using [1251]albumin as a plasma marker and technetium-99m as a red blood cell marke...
