Effect of luminal somatostatin on acid secretion and gastrin release

Scandinavian Journal of Gastroenterology
R G Fiddian-GreenP Kothary

Abstract

The mechanisms by which somatostatin inhibits acid secretion when infused into the lumen of the stomach have been examined in 20 healthy subjects. The acid secretory response to distension with 500 ml of neutral water was examined in nine successive 10-min test periods in each subject. Samples of serum and boiled neutral gastric juice were collected and frozen for later immunoassay for gastrin. Somatostatin was added to the distending fluid in a concentration of 600 pg/ml in the middle 3 test periods in 10 test subjects, and placebo added in the same 3 test periods in 10 control subjects. The addition of somatostatin inhibited the rate of acid secretion as compared with placebo alone in the control subjects (p < 0.025) without altering the concentration of immunoreactive gastrin in the serum but reducing the concentration of immunoreactive gastrin in gastric juice (p < 0.02). The data are consistent with the suggestions that the intraluminal administration of somatostatin inhibits antral gastrin release in a paracrinic manner and inhibits acid secretion indirectly by inhibiting lumina gastrin-mediated acid secretory activity.

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
