Cerebral metabolic and hemodynamic activities of l-eburnamonine in the anesthetized dog. A comparison with vincamine

P LacroixJ B Le Polles


1. The cerebral metabolic and hemodynamic activities of l-eburnamonine (l-E) were investigated in anesthetized dogs and compared with those of vincamine (Vi). 2. The injection of l-E (2 mg/kg i.v.) increased vertebral, carotid and femoral blood flows (VBF, CBF, FBF) while corresponding resistances decreased. aortic blood flow (A0 BF) and systolic ejection volume (SEV) increased. Cerebral O2 and glucose consumption (CMRO2, CMRG) increased as did the O2 extraction coefficient and the O2 supply. This last increase was due to the simultaneous increase of VBF, hemoglobin (Hb) and arterial pO2.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
