The isotope, electromagnetic and resistographic investigation showed phenoxybenzamine to be capable of producing different effects on the blood supply of different regions of the brain. The preparation enhanced the circulation of the vertebro-basilar system and decreased it in the carotic one. Phenoxybenzamine also significantly inhibited the nervous control of the cerebral circulation. It inhibited the reflex reaction of cerebral vessels, changed the cerebral blood flow by stimulation of cervical sympathetic nerves and was capable of protecting against experimental cerebrovascular disorders. These data allow one to recommend phenoxybenzamine in neurological and neurosurgical clinics for the treatment of cerebrovascular disorders in the vertebro-basilar arterial system.

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.
