Extracellular volume regulation and growth.
We have formalized extracellular and intracellular volume interaction with each other and the influence of these processes on the type of cell growth. The linearized model was verified by stereo metric solution and the results were compared with experimental data. Two theoretical solutions were found: Solution 1, extracellular volume (ECV) was calculated to be about 23% of total body volume (TV...
متن کاملRegulation of extracellular fluid volume and blood pressure by pendrin.
Na(+) is commonly designed as the culprit of salt-sensitive hypertension but several studies suggest that abnormal Cl(-) transport is in fact the triggering mechanism. This review focuses on the regulation of blood pressure (BP) by pendrin, an apical Cl(-)/HCO(3)(-) exchanger which mediates HCO(3)(-) secretion and transcellular Cl(-) transport in type B intercalated cells (B-ICs) of the distal ...
متن کاملThe extracellular regulation of growth factor action.
The concept that growth factors act as autocrine and paracrine regulators of cell growth and differentiation was introduced over a decade ago (Sporn and Todaro, 1980). Since then significant advances have been made in understanding the regulation of growth factor expression and interaction with high affinity plasma membrane receptors. More recently, structural analysis and in vitro experiments ...
متن کاملBlood volume and extracellular fluid volume in anesthesia.
From every day experience we find that the accepted standards and indices for the quantitative adequacy of the circulating blood, such as hemoglobin-gms and hematocrit percents, are not adequate and do not reflect volume or mass. The laboratory tests that we have habitually adopted as guidelines denote percentage concentration per unit volume and not absolute amounts. There is all the differenc...
متن کاملDynamic Regulation of Cell Volume and Extracellular ATP of Human Erythrocytes
INTRODUCTION The peptide mastoparan 7 (MST7) triggered in human erythrocytes (rbcs) the release of ATP and swelling. Since swelling is a well-known inducer of ATP release, and extracellular (ATPe), interacting with P (purinergic) receptors, can affect cell volume (Vr), we explored the dynamic regulation between Vr and ATPe. METHODS AND TREATMENTS We made a quantitative assessment of MST7-depe...
