Abstract

To clarify whether neutrophils and platelets are implicated in the pathogenesis of focal hepatocellular necrosis in endotoxaemia, we examined the relationship between the changes in neutrophils and platelets in peripheral blood and the degree of focal hepatocellular necrosis and serum transaminase activity in rats after endotoxin injection. The number of neutrophils in the peripheral blood decreased rapidly during the first hour after endotoxin injection and then increased. This initial decrease might be caused by the adhesion of neutrophils to pulmonary capillary walls, and the subsequent increase might be caused by granulocyte colony-stimulating factor mediated by endotoxin. However, there was no relationship between the degree of focal hepatocellular necrosis and the number of neutrophils sticking to the walls of hepatic sinusoids or the changes in the neutrophil count in the peripheral blood. The number of platelets in the peripheral blood decreased rapidly after endotoxin injection. There was a statistically significant relationship between the number of platelets in the peripheral blood and the level of serum transaminase activity: the fewer the platelets, the more severe was focal hepatocellular necrosis. The present stu...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.
