The serum level of erythropoietin was measured in 31 patients with anemia secondary to chronic infection or malignancy and compared with erythropoietin levels in 23 patients with iron-deficiency anemia and 14 patients with primary hematopoietic diseases. Erythropoietin levels varied directly with the degree of anemia in patients with iron deficiency or primary hematopoietic disorders. There was...
BACKGROUND Doxorubicin is a highly effective antineoplastic drug, but its clinical use is limited by its adverse side effects on the heart. We investigated possible protective effects of erythropoietin against doxorubicin-induced cardiomyopathy. METHODS AND RESULTS Cardiomyopathy was induced in mice by a single intraperitoneal injection of doxorubicin (15 mg/kg). In some cases, human recombin...
Erythropoietin, known for its role in erythroid differentiation, has been shown to be neuroprotective during brain ischaemia in adult animal models. Although high levels of erythropoietin receptor are produced in embryonic brain, the role of erythropoietin during brain development is uncertain. We now provide evidence that erythropoietin acts to stimulate neural progenitor cells and to prevent ...
Erythropoietin, a plasma glycoprotein produced primarily by the kidney, is a growth and differentiation factor for erythroid progenitor cells. Production of renal erythropoietin is regulated by modulation of mRNA levels in response to changes in tissue oxygenation. Exposure to cobalt, a nonphysiologic stimulus for erythropoietin production, also acts by inducing mRNA accumulation. To determine ...
Pregnant women often develop anemia concomitant with the increase in serum erythropoietin levels, which are actually lower than those of nonpregnant anemic women due to the possible suppressive effect of endogenous estradiol on erythropoietin induction. The anemia, derived from hemodilution, does not act as a drive for erythropoietin induction, but iron deficiency, often observed during pregnan...
PURPOSE Erythropoietin is responsible for regulating the growth and development of red blood cells. Reports conflict on whether skeletal muscle is able to produce erythropoietin and release it into circulation and if exercise affects this. We set out to determine how erythropoietin is regulated in skeletal muscle and to determine whether skeletal muscle-derived erythropoietin can stimulate eryt...
OBJECTIVE To examine the number and volume of red blood cell transfusions (RBCTs) in very and extremely low birthweight infants under restrictive red blood cell transfusion guidelines without erythropoietin administration, and to compare the results with those reported in similar infants receiving erythropoietin. METHODS From April 1996 to June 1999, all RBCTs given to infants with a birth we...
The expression of the hypoxia-inducible protein erythropoietin in tumour cells correlates with levels of tumour hypoxia. Our aim was to look for an interrelation of directly measured oxygenation levels, the presence of tissue erythropoietin and its receptor. Data of tumour oxygenation status, plasma and tissue erythropoietin and its receptor in a group of spontaneously occurring tumours in 15 d...
Background: Methanol is a highly toxic alcohol and causes such severe side effects as CNS depression, blindness, acute renal failure and even death. Methods: Patients were three male referrals (aged 29-56 years) to the poisoning center at Taleghani Hospital, Urmia, Iran, in 2020. They had unknowingly ingested methanol. Their chief problems were bilateral blindness and metabolic acidosis. Upon ...
