Abstract

The dogs and rabbits, electrical stimulation of the vertebral nerve reduced the pressure in the carotid and the vertebral--basillar arterial systems leaving the general arterial pressure unaltered. Simultaneously the values of pH, PO2 PCO2, and buffer bases decreased in the blood flowing from the dog brain. The data obtained suggest that stimulation of the vertebral nerve reduces the blood flow in the vertebral artery which, in conditions of occlusion of the contralateral vertebral artery, leads to the circulatory regional hypoxia of the brain.

COVID-19

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.
