Acid-base changes in milk and blood of rats in acidosis and alkalosis

The American Journal of Physiology
R YagilG M Berlyne


Lactating white rats (Rattus norvegicus) were subjected to metabolic and respiratory acidosis and metabolic alkalosis. Before and during the various treatments, the acid-base status of heart blood and milk was determined. Acute metabolic acidosis lowered the pH of plasma and milk; Pco(2) and bicarbonate concentrations in plasma were lowered, and in milk Pco(2) was raised and the bicarbonate concentration remained unchanged. Respiratory acidosis and acetazolamide caused a drop in blood pH and in blood and milk bicarbonate concentrations; milk pH remained unchanged, but Pco(2) was raised in both plasma and milk. Acute metabolic alkalosis raised the blood pH and milk Pco(2); plasma Pco(2) and bicarbonate concentrations in blood and milk remained unchanged. The data show that greater changes occur in acid-base parameters of blood than milk when animals are exposed to acidifying and alkalinizing stimuli.

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.
