Abstract

The influence was studied of 3 and 6 gamma/kg/min. dopamine on the blood volume in the liver, abdomen, chest, arms and legs in ten volunteers with healthy livers, and a comparison was made between the effect of dopamine and the blood volume changes caused in these body regions by inflatable whole-leg boots at a pressure of 40 mm Hg. Regional blood volumes and any induced changes were studied by means of 99 m Tc labelled autologous erythrocytes. A gamma camera with a pinhole collimator and a small computer was used, the field of vision of the camera being 148 cm in diameter. Changes in regional activity reflect changes in the regional blood volume. 1. Whole-leg compression at 40 mm Hg led to an increase in the blood volume of the liver, abdomen and chest, but to a reduction in the legs, while no significant change was observed in the arm blood volume. 2. On infusion of 3 gamma/kg/min. dopamine for 15 minutes no significant change occurred in the blood volume of the liver and abdomen. The chest blood volume increased, while the blood volume of the upper and the lower extremities showed a statistically significant decrease. 3. On infusion of 6 gamma/kg/min. dopamine for 10 minutes no significant change occurred in the blood volume...Continue Reading

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
