Abstract

Salicylamide glucuronide (SAMG) in 0-6 and 6-12 hours-urine specimens was determined after oral administration of salicylamide in 7 normal volunteers (NV), in 51 cases of various liver diseases and hyperbilirubinemias, and in 19 cases after drug administration, to predict the in vivo drug metabolism in man and its change by drugs. Maximal glucuronide formation was obtained by 1.0 g of salicylamide administered to NV; thus, this dosage was used in the present study. SAMG as percent of total salicylamide, the percent of SAMG, from 0-6 hours-urine specimens was high and constant in NV (71.3 +/- 8.3 (Mean +/- S.D.)). 0-0.08% of the total salicylamide was confirmed as free salicylamide in 0-12 hours-urine specimens of NV. The percent of SAMG of 0-6 hours-urine specimens was 57.2 +/- 8.6 in acute hepatitis, 66.6 +/- 10.9 in chronic hepatitis, and 48.6 +/- 10.7 in liver cirrhosis (mean +/- S.D.). Free salicylamide increased slightly in liver diseases. Serum bilirubin levels tended to be inversely correlated with the percent of SAMG. In most cases of Gilbert's syndrome, the percent of SAMG remained at a normal level. The percent of SAMG in cases with unconjugated hyperbilirubinemias of other geneses were almost within normal limits. Bu...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.
