Kidneys with a complete parenchymal bridge in the sinus, which is diagnostic for a duplex collecting system, were also excluded from the study. The children were between 1 month and 18 years old (mean age, 6.1 Â± 5.9 years).he objective of our study was to develop, by use of ultrasound, nomograms of renal parenchymal thickness, medullary pyramid thickness (height), renal length, and the ratio of medullary pyramid thickness to parenchymal thickness in healthy children.
erythropoietin. a glycoprotein hormone secreted by the kidney in the adult and by the liver in the fetus, which acts on stem cells of the bone marrow to stimulate red blood cell production (erythropoiesis).
Red blood cell hormone modulates the immune system. FULL STORY. New research reveals that a hormone best known for stimulating the production of red blood cells can modulate the immune response. The study finds that erythropoietin (EPO) has contrasting influences on infectious and inflammatory diseases and may be useful in the design of new therapeutic strategies. FULL STORY.
